The technical field

The present invention relates generally to off-road vehicles and, in particular, to a transmission node for off-road vehicles, which combines the functions of a torque limiting and brake.

The level of technology

Off-road vehicles are usually equipped with a brake system with discs and brake pads to ensure braking off-road vehicles. U.S. patent No. 6883630, the content of which is incorporated here by reference, describes the nodes of the front disc brakes installed on the left and right connection elements of the universal joint, passing the left and right of the front differential, each of which is connected to the respective left and right axle shafts that transmit power from the front differential to the front wheels. Left and right brake caliper is rigidly mounted on the hull design of the front differential. The rear brake system described in U.S. patent No. 6883630 consists of a single node, disc brakes, United with spider universal joint in the front from the rear corner of the transmission connecting the drive shaft that goes from the engine to the rear corner of the transmission. Thus, a single disc brake rotates with the drive shaft, while the rear caliper is ormosa is rigidly connected to the hull design of the rear corner of the transmission.

Although this system works well and provides sufficient braking in dry and wet conditions, there are conditions, such as when off-road vehicle moves through the water or swamp, where the friction between the brake pads and the brake disc is reduced and, thus, the braking force is also reduced. There are other cases when the brake discs can be covered with dirt or other contaminants, and, thus, the braking force can also be reduced.

Rear-wheel drive conventional off-road vehicle has a rigid drive shaft connected between the motor and the rear hub angular gear. Drive shaft transmits torque from the transmission to the engine left and right rear axle shafts for rotation of the wheels and providing a driving force to the rear wheels. The torque is transmitted continuously from the engine to the wheels. In some cases, when the wheels of off-road vehicles rise from the ground, for example, when the off-road vehicle jumps over bumps, while the torque is still transmitted to the wheels from the engine, powertrain components generate very high torque when the wheel again abruptly come in contact with the ground under the weight of the vehicle. To prevent failure of the drivetrain components on who should have the appropriate size, respectively, and thus should be larger/heavier and more expensive than it would be if they were designed only to work with the torque of the engine.

To reduce the size of components, preserving the longevity and prevention of failures in the transmission are friction clutches. A friction clutch is a series of alternating leading and trailing discs that are put into contact with each other spring mechanisms such as Belleville springs or a set of standard spiral springs. Leading the disks are connected with the previous transmission side of the transmission and driven disks connected with the subsequent transmission side of the transmission. Torque must pass through the master and slave disks to pass from the engine to the wheels and Vice versa. The amount of torque which the friction clutch can transmit without slipping between the master and slave drives are determined by the power supplied to the disk stack by a spring mechanism. Force required for the spring mechanism, is determined by the maximum torque it can withstand the components of the transmission. Any torque that is higher than the maximum torque will cause slippage within the slip clutch that will protect driveline components.

Thus there is a need for an off-road vehicle having a compact transmission, which mitigates some of the disadvantages of conventional transmissions and brake systems for off-road vehicles.

Preferably, the engine includes the as well as the transmission or transmission, in the working position connected with it (not shown), such as the node engine/powertrain described in published patent application U.S. No. 2006-0231322, the full contents of which are incorporated here by reference. System 50 of the front wheel includes a drive shaft or the drive shaft 52, which is connected and transmits power between the transmission and the gear 54. It should be noted that the gear 54 may be a differential gear type, which permits relative rotational movement between the left and right wheel nodes 18 and 19. May also be used in the differential-type Visco-LokŪ. In Fig. 2 shows the gear 54, as the differential gear type, but you can use any other type of transmission unit, which is capable of transmitting torque between the drive shaft 52 and the wheel nodes 18, 19. The gear 54 in the operating position is connected to each wheel hub 56 of the front wheels of the nodes 18, 19 through the respective shafts 58, 60. Shafts 58, 60 are designed for power transmission between the gear 54 and the hub 56. It should be noted that each axle 58, 60 may include one or more universal joints or connections with grooves and balls, which provide for power transmission and motion the wheel of the nodes 18, 19. Front brake system 62 includes a pair of brake discs 64 on both sides of transmissional the node 54 and a corresponding pair of calipers 66 brakes. Calipers 66 brake rigidly mounted on the housing front gear 54, while the disks 64 are connected directly with the left and right half shafts 58, 60.

Rear transmission 70 of the vehicle 10 includes a transmission node 100, mounted on the rear side 13 of the frame 12, which in the working position is connected with the engine/transmission (not shown) via a second drive shaft 78 and in the working position is connected with the rear hub 72 of the rear wheel of the nodes 20 and 21 through the respective shafts 74, 76. The transmission node 100 contains a gear 115 (Fig. 4 and 5), ensuring the transfer of the right angle between the second drive shaft 78 and the axes 74, 76, which may be a differential gear or dedifferentiated type rear brake mechanism 150 (Fig. 4 and 5) and the mechanism 170 torque limiting (Fig. 4 and 5), so that the transmission node 100 combines all the main power transmission and control system rear-wheel drive 70 in a compact design.

As shown in Fig. 3, the transmission node 100 has a main body 102 having a rear portion 104 containing a gear mechanism, and the front portion 106 that contains the rear brake mechanism 150 and the mechanism 170 torque limit. The rear portion 104 of the main body 102 is closed the side cover 112 of the casing, while the front portion 106 of the main body 102 is closed front the second cover 114 of the housing. Side cover 112 of the housing and the front cover 114 of the housing attached to the main body 102 by means of fixing means 117, such as bolts. The front portion 106 of the main body 102 includes a piston 80 of the hydraulic brakes and the inlet opening 82 for the working fluid, which is connected by line 84 hydraulic brakes (Fig. 1). The main body 102 includes three transverse mounting bracket 107, 108 and 109 for attaching the rear portion 104 of the main body 102 to the frame 12 by means of fasteners inserted through them, and two longitudinal bracket 110 and 111 for attaching the front portion 106 of the main body 102 to the frame 12 by means of fixing means.

As shown in Fig. 4 and 5, which are the three-dimensional image of the transmission node 100, node 115 bevel gear transmission consists of a crown gear 116 and the pinion 130 and is located inside the main body 102 and held them. Crown gear 116 mounted within the cavity 105 of the rear portion 104 of the main body 102 and is attached and held by a pair of ball bearings 118, 120, which allow rotation of the crown gear 116 around the transverse axis 121 of the rotation with minimal friction. Crown gear 116 has a Central hole 122 having slots 124 on its inner wall which are adapted for engagement with splined ends on the of WASA 74, 76 (2), inserted, when the transmission node 100 is installed on the vehicle 10 during Assembly of the vehicle 10. Leading gear 130 contains a bevel gear part 132, an elongated portion 134, protruding from one end of the bevel gear part 132, and a portion 136 of the shaft protruding from the other end of the bevel gear 132. The elongated part 134 pinion 130 is inserted into the cavity 138 of the rear portion 104 of the main body 102 and is retained for rotational movement of the needle bearing 140. The portion 136 of the shaft pinion 130 is retained for rotational movement by a bearing 142 mounted within the front portion 106 of the main body 102. Bevel gear portion 132 pinion 130 engages with a crown gear 116 at point 146 and rotational movement of the pinion 130 around the longitudinal axis 148 is converted into rotational movement of the crown gear 116 around the transverse axis 121 of the rotation.

It should be noted that illustrates the transmission node 100 contains a node bevel gear 115 dedifferentiated type, while it can be a differential type or any other type of gear, which is able to transfer power between the drive shaft 78 and the wheel nodes 20, 21.

The portion 136 of the shaft pinion 130 is connected to the rear brake mechanism with which the present from node 150 clutch for braking in wet conditions. The outer member 152 of the friction clutch is connected with the portion 136 of the shaft pinion 130. The outer member 152 of the friction clutch has an internal splined hole 153 which engages with the splined end 154 of part 136 of the shaft pinion 130. The outer member 152 of the slip clutch attached to the portion 136 of the shaft pinion nut 130 164. Node 150 clutch braking in wet conditions the package contains a fixed disks 156 and rotating discs 158. Fixed disks 156 have grooves in their outer peripheral surfaces and engage with the slots 159 on the inner wall 160 of the front portion 106 of the main body 102 and are thus fixed. Rotating disks 158 have grooves on their inner circumference and engage with the slots 162 on the outer element 152 friction clutches and thus rotate together with the pinion 130.

Node 150 clutch braking in wet conditions is actuated ball actuator 166 of the inclined surface includes a leading Cam 167, a driven Cam 168 located adjacent to the package fixed disks 156 and rotating discs 158, and many steel balls 171 (figa). Leading Cam 167 relies on a needle bearing 165 so that it can easily rotate. Leading Cam 167 includes several grooves 163 of variable depth (figa), which are steel the ariki 171, and the lever 169 which is connected with a hydraulic piston 80 and is controlled by the mechanism 44 rear brake set left on the steering wheel 26 (Fig 1), or pedal (not shown). In operation, when the mechanism 44 to actuate the rear brake is pressed by the driver, the working fluid is supplied under pressure to the hydraulic piston 80, which, in turn, presses on the lever 169 which rotates the Cam 167. The working fluid within the brake piston 80 is sealed from the internal space in the main body 102, so that mixing with the brake fluid medium does not occur. As shown in figa leading Cam 167 is based on needle bearings 165 to facilitate its rotation. Leading Cam 167 contains several grooves 163 of variable depth (shown only one) on the side facing the slave fist 168. In the grooves 163 variable depth steel balls inserted 171. On figa leading Cam 167 does not rotate, and steel balls 171 delayed the bottom of the slots 163 variable depth so that the leading Cam 167 and a driven Cam 168 is separated by a distance dl. When the mechanism 44 to actuate the rear brake is pressed by the driver, the leading Cam 167 is rotated in the direction R1, as shown in figv, so that the clutch Cam 168 is pushed in the direction P1 of the steel balls 171, rising in the basics 163 variable depth, and to the stationary disks 156 and rotating disks 158 is attached axial force. Stationary discs 156 are pressed against the rotating discs 158, resulting in a slowdown of the outer member 152 with a friction clutch connected to the rotating disk 158. As the outer member 152 of the friction clutch is connected with the pinion 130, which is connected with a crown gear 116, the braking force is effectively attached to the rear wheel assemblies 20, 21, thus slowing the movement of the vehicle 10.

It is implied that, although the illustrated drive system hydraulic brakes, node 166 inclined surface with the ball can operate a cable connected at one end with the lever 169 which rotates the Cam 167, and the other end of the mechanism 44 rear brakes installed on the left on the steering wheel 26 (Fig 1).

As shown in figure 4 and 5, the outer member 152 of the friction clutch is also part of the mechanism 170 torque limit, which is a preceding transmission with respect to the host 150 braking in wet conditions. Mechanism 170 torque limiting consists of a friction clutch comprising an outer element 152 of the friction clutch, the inner element 176 friction clutches, wheel discs 182 and driven disks 180, the presser element 178 and the bias element in the form of Belleville springs 18. The outer member 152 of the slip clutch includes an annular front portion 174 having an inner wall 186, which has a lot of grooves 188, which receive corresponding external teeth 190 (5) of the slave disk 180 so that the driven disks 180 rotate together with the outer element 152 of the friction clutch. Internal element 176 of the slip clutch has a Central portion 192 of the shaft having a splined end 195, made with the possibility of connection with the drive shaft 78 (figure 2). Internal element 176 of the friction clutch comprises a cylindrical wall 196, having a set of grooves or slots 198 for receiving the internal teeth (not shown) leading drive 182 so that the leading discs 182 rotate with the inner member 176 of the friction clutch. Internal element 176 of the slip clutch also includes a flange portion 202. Internal element 176 of the friction clutch is held in an aligned position relative to the longitudinal axis 148 of rotation and held a short shaft 194, protruding from the nut 164, and the ball bearing 200, mounted on the front cover 114 of the main body 102. Spring washers 184 adjacent to the inner portion 204 of the retainer plate 178 and keep the master and slave disks 180, 182 in coupled state to a specified pressure corresponding to the set maximum torque limit for the mi of which the master and slave disks 180, 182 will slip, thereby eliminating potential damage due to excessive torque acting on the various components of the rear actuator 70. Force required to banana mechanism is determined by the maximum torque distributed to the components of the transmission. Any torque above the specified maximum torque will cause slippage leading and trailing disks 180, 182 within mechanism 170 torque limit that will protect driveline components.

The main body 102 filled with lubricating fluid medium, which lubricates the gear 115, the rear brake mechanism 150 and the mechanism 170 torque limit, so that the main components of the transmission node 100 are lubricated with the same fluid medium, which eliminates the need to seal the main components from each other. Only the hydraulic piston hydraulic brake 80 is sealed relative to the main body 102.

Leading gear 130, the node 150 clutch braking in wet conditions and mechanism 170 torque limiting coaxially with the longitudinal axis 148 so that the node 150 clutch braking in wet conditions and mechanism 170 torque limit are very close to each other and the transmission node 100 compact.

To the to shown in Fig. 7 is a schematic view in plan of the transmission of the vehicle 10, the power from the node 215 of the engine/transmission is transmitted to the front and rear wheels nodes 18, 19, 20, 21 through the drive shaft 52 and 78 connected to the node 215 engine/powertrain. The drive shaft 52 is connected with the front gear 54, which transmits the driving force from the node 215 of the engine/transmission to the left and right axle shafts 58 and 60. Brake discs and calipers 64, 66 are located on both sides of the front gear 54 and provide a braking force for the front wheels of the nodes 18, 19. The drive shaft 78 is connected to the transmission node 100. The transmission node 100 driving force from the node 215 engine/powertrain initially passes through the mechanism 170 torque limit and then through the gear 115, which transmits driving force to the left and right axle shafts 74 and 76. Node 150 clutch braking in wet conditions is between mechanism 170 torque limit and the gear 115 and provides a braking force for the rear wheel of the nodes 20, 21. As shown, the node 150 clutch braking in wet conditions, the mechanism 170 torque limit and the drive shaft 78 are aligned, providing a compact design of the transmission node 100.

In Fig. 8 shows a schematic view in plan of a second variant implementation of the transmission of the vehicle is which includes two transmission unit 100 and 240; one in the front part 220 transmission and one in the rear part 222 of the transmission. The rear portion 222 of the transmission is identical to the rear of the transmission of the vehicle 10, shown in Fig. 1, 2 and 7, while the front part 220 includes the second transmission node 240, which is identical to the transmission node 100, but oriented in the opposite direction. The driving force from the node 215 of the engine/transmission is transmitted to the front wheel assemblies 230, 232 through the drive shaft 234 and through the front of the transmission node 240. The driving force from the drive shaft 234 initially passes through the mechanism 270 torque limit and then through the node 225 bevel gear mechanism that transmits the driving force of the left and right front axle shafts 258 and 260. The node 250 clutch braking in wet conditions is between mechanism 270 torque limit and the node 225 bevel gear transmission and provides a braking force for the front wheel nodes 230, 232.

In Fig. 9 shows a schematic view of the third variant of execution of the transmission, including the transmission node 300. As shown, the transmission node 300 contains a mechanism 370 torque limiting and node 350 clutch braking in wet conditions, but is separated from the node 315 bevel gear. The motor 215 is connected to the transmission node 300 through the drive shaft 378 and transmissio the hydrated node 300 is connected to the node 315 bevel gear through a short shaft 379. Mechanism 370 torque limiting and node 350 clutch braking in wet conditions are aligned and housed in the same housing 301, which has a relatively smaller and more compact than the main body 102 of the transmission node 100.

In Fig. 10 shows a schematic view of a fourth variant of execution of the transmission, including the transmission node 500. As shown, the transmission node 500 includes a mechanism 570 torque limit, the node 550 clutch braking in wet conditions and the node 515 bevel gear transmission. The transmission node 500 also includes a differential 510, in the working position connected with a crown gear 516 node 515 bevel gear, which permits relative rotational movement between the left and right wheels 20 and 21. The motor 215 is connected to the transmission node 500 drive shaft 578. The mechanism 570 torque limit and the node 550 clutch braking in wet conditions are aligned in the main body 501 of the transmission node 500. The node 515 bevel gear transmission and differential 510 are also located in the main body 501. Also envisaged that the node 515 bevel gear transmission and differential 510 may be located separately from the main body 501 is similar to the transmission node 300 shown in Fig. 9.

In Fig. 11 and 12 until the ANO specialized vehicle 430. Specialized vehicle 430 has a frame 432, which includes a body 434 of the vehicle. Four wheel 436 is suspended on the frame 432 by means of suspension elements (not shown). Each of the four wheels 436 has a bus 438. It is assumed that a specialized vehicle 430 may have six or more wheels 436. As shown in Fig. 12, a pair of seats 440, each of which has a base 441 and 442 back, installed in the transverse direction next to each other on the frame 432 to accommodate the driver and passenger of a specialized vehicle 430.
