The invention relates to transport machinery, and more particularly to a vehicle driven by muscle power of the driver.

Currently known bike /see ed. mon. N 1104045, CL A 62 K 5/02), containing frame, at least three wheels, a seat, a pedal-and-rod drive, front wheel steering with steering shaft and tie rods, rear wheels, while the frame is made of two chaste, pivotally interconnected by means of horizontal axis, the upper ends of the front frame interlocked by means of the resilient seat with steering column mounted on the specified axis, covering the steering shaft, one end of which is placed a gear with a steering wheel, and with the other end connected with the steering rod with the rear wheels of a Bicycle. Also known bike (see U.S. patent N 4740004, 280-269, class B 62 K 5/08), the awn of rotation around the vertical axis and connected to the steering actuator. The latter contains a vertical shaft mounted to rotate on the frame, a wheel mounted on the upper end of the shaft, and a transverse rod connected middle part of the shaft and the front wheels. To the lower end of the shaft attached to the basket for cargo.

The closest technical solution is the vehicle [1] , driven by muscle power of the driver containing the base that hosts the crank-pedal chain drive, while the driven sprocket located on an additional element, the seat is configured to move along the front of the base and fixing in any of the intermediate positions, overrunning clutch for connecting the drive wheels, rear wheel, two front steered wheels, the associated wheel around the driver from below, and the relationship of the front wheels between a made in the form of driveline, the base is made of pivotally connected horizontal axis parts connected by a shock absorber, each of the front wheels mounted on a hollow axis, within which is rotatably shaft associated with this wheel, and the outer end is behind the axle. The disadvantage of the criminal code of the management.

The objective of the invention is to simplify the construction, increase ease of use and management.

This is achieved in that in the vehicle driven by muscle power of the driver containing the base that hosts the crank-pedal drive chain predica, while the driven sprocket located on an additional element, the seat is configured to move along the front of the base and fixing in any of the intermediate positions, overrunning clutch for connecting the drive wheel, rear wheel, two front steered wheels, the associated wheel around the driver from below, and the relationship of the front wheels between a made in the form of driveline, the base is made of pivotally connected horizontal axis parts connected by a shock absorber, each of the front wheels mounted on a hollow axis, within which is rotatably shaft associated with this wheel, and the outer end is behind the axle, the wheel is made in the form samoobrazovyvalas pipe, and its relation to the wheels through hard rods installed with the possibility of rotation around the vertical axis. Transport creditmortgage posted sleeve, associated with it by rolling the spline, while the driven sprocket of the chain drive is mounted on the control shaft and its sleeve with the relevant parties, through the drive shafts are connected with the inner ends of the shafts installed in each axis, and the outer ends of these shafts connected to the wheels via a freewheel clutches.

In addition, the vehicle may have a PTO transmission in the form of a flexible shaft.

In Fig. 1 is a perspective view of the vehicle of Fig. 2 is a top view in Fig. 1; Fig. 3 - section a-a in Fig. 2.

The vehicle driven by muscle power of the driver (see Fig. 1-3), contains a base, made in the form of two pivotally connected by a horizontal axle parts - front 1 and rear 2, which additionally interconnected by the damper 3. On the front part 1 of the base installed bike the drive, including the carriage 4 with two cranks 5 and 6 pedals, wheel sprocket 7, the ratchet with the slave sprocket 8, the circuit 9, and a front 10 and rear 11 switches the transmission. On the front part 1, the Foundation also established a beam 12 of the mounting of the front wheels, a seat 13, the steering mechanism and to the Ah 15, closed protective shields 16, has a drive shaft 17, on which is mounted the said ratchet with guest stars 8.

Inside the drive shaft 17, being with him in the movable splined connection, there are two bushings 18 (right and left), forming a sliding link.

On the ends of the beam 12 is pivotally mounted brackets 19 (right and left), with the possibility of rotation around the vertical axis 20. Each bracket 19 a cantilever hollow shaft 21, on which the bearings 22 mounted wheel 23, secured with a spring washer 24. Inside axis 21 on the bearings 25 is a shaft 26, the outer end of which, the speaker for the axle, rigidly connected with the driving member of the clutch 27, and the wheel - with her slave link. The inner end of the shaft 26 is connected with the sleeve 18 sliding link through a double universal joints or flexible shaft 28.

Installed on the front part 1 of the base seat 13 has the ability to guides 29 and fixation in any of the intermediate positions.

On the front part 1 of the base is also pivotally mounted on the bracket of the steering wheel 30 can be rotated around a vertical axis, which is fixed to the wheel 31 in the form of Samoobrona is 32 (left and right), moreover, the coordinates of the corresponding axis of the hinge rod relative to the axis of rotation of the wheel bracket 19 and the rotation of the steering bracket 30 are located in a particular geometric dependencies.

On the back 2 base rear wheel, brake, and also the trunk.

The vehicle operates as follows.

In rectilinear motion when pedaling torque is transmitted from the drive sprocket 7 through a chain transmission to the driven sprocket 8, the driving shaft 17 and the slotted sleeve 18. Each of the slotted bushing transmits rotation through the corresponding dual hinge clutch 28 or the flexible shaft to the wheel shaft 26, which by means of the freewheel 27 causes the rotation of the wheel. Upon termination effects pedal freewheel 27 (right and left) will open and the vehicle continues to move under the action of the inertial force.

When turning the steering wheel each wheel by means of the rod 32 is rotated to the appropriate angle, the double universal joints 28 (or flexible shafts) with sliding link transmit rotation of the drive wheels 23, compensating for the geometric offset of the axes of the drive shaft 17 and wheels. The presence in each Coles and to simplify the design.

1. The vehicle driven by muscle power of the driver containing the base that hosts the crank-pedal drive and chain transmission, while the driven sprocket located on an additional element, the seat is configured to move along the front of the base and fixing in any of the intermediate positions, overrunning clutch for connecting the drive wheel, rear wheel, two front steered wheels, the associated wheel around the driver from below, and the relationship of the front wheels between a made in the form of a cardan transmission, the base is made of pivotally connected horizontal axes of the parts connected by the absorber, kaidon of front wheels mounted on a hollow axis, within which is rotatably bodies associated with this wheel, and the outer end is behind the axle, wherein the wheel is made in the form Samoobrona curved pipe and its connection with wheels made by rigid rods installed with the possibility of rotation around the vertical axis, it is provided with a sliding element made of a drive shaft mounted for rotation, inside of which is placed VTI installed on the control shaft, and its sleeve with the relevant parties, through the drive shafts are connected with the inner ends of the shafts installed in each axis, and the outer ends of these shafts connected to the wheels via a freewheel clutches.

2. Vehicle under item 1, characterized in that the cardan transmission is made in the form of a flexible shaft.
