The invention relates to wheeled vehicles (CCC) with all the leading managed multi-turn wheels and the body, with remote control.

For the prototype accepted technical solution for patents for invention, EN 2291808, 2003 "Wheeled vehicle", 2342275, 2008 "Mechanisms of wheeled vehicles and the application for invention No. 2008151806 "Remotely controlled wheeled vehicle," the decision to grant a patent for an invention which issued 10.11.2009,

Remotely managed the CCC contains a wheeled platform with at least three wheel pairs, rotatable relative to the Central vertical axis of the wheeled platform body, the tower with the mechanism of stabilization of its position, support rollers, a battery, two electric motors to provide movement and rotation of the body, the Central gear, the transmission to the chassis, the actuator, brake, depreciation wheels and unit equipment for remote control of the vehicle. The transmission provides transmission of torque from the left motor through the left bevel gear, the Central gear, the follower wheel which is connected with a leading asterisk first chain drive to each wheel pair by the same chain with the tensioner on the led star and, United with driveshafts cross-axle differentials. The rotation of the body relative to the wheeled platform is from the right motor for the second bevel gear, the Central gear, the follower wheel which is connected to the upper part of the body of the wheeled platform. Turn all wheel pairs occurs when the rotation of the body relative to the wheeled platform from the bottom of the shaft of the Central gear connected with the body and with a cylindrical pinion gear, follower wheel which is connected with a leading asterisk second chain of transmission, each of the rotary column by means of a chain driven sprocket connected to the rotary columns. The mechanical brake of the type installed between the gearbox and the first toothed bevel gear, the Central gear. Depreciation of the wheels is accomplished by installing a spring leaf springs and telescopic shock absorbers on the rotary column wheelset. Stabilization of the position of the turret relative to the cardinal directions in the horizontal plane is achieved when turning the CCC by turning it relative to the body in the opposite direction and at the same angle with the help of cylindrical and bevel gears in the Central gearbox.

The disadvantage of the prototype design is the complexity of the drive and control mechanism is ZMA stabilization of the tower.

The technical result of the invention, modifying, simplifying the design of the drive and control mechanism for stabilizing the position of the turret.

The declared design of the CCC with remote control contains a wheeled platform with at least three wheel pairs, rotatable relative to the wheeled platform body, the tower with the mechanism of stabilization of its position, support rollers, a battery, two electric motor for driving the tool, rotate the body and wheel pairs, the Central gear, the transmission to the chassis, the actuator, brake, depreciation wheels and unit equipment for remote control means. The rotation of the body relative to the Central vertical axis of the wheeled platform is from the right of the motor via a coupling on the right gear bevel gear, the Central gear, the follower wheel which is rigidly connected to the Central vertical axis with the bottom of the chassis of a wheeled platform. Turn all wheel pairs occur synchronously and at the same angle as the body when it is rotated about a Central vertical axis of the wheeled platform by means of a pipe rigidly connected to the horizontal support shaft of the Central gear and two leading chain sprockets gears and the driven sprocket rigidly connected with turn signals the mi loudspeakers and enclosures cross-axle differentials wheelset. Stabilization of the position of the turret relative to the cardinal directions in the horizontal plane while maneuvering of the vehicle is achieved by combining it with the case wheeled platform with controllable gear clutch, the leading half coupling rigidly connected with the driven toothed bevel wheel gear drive transmission rotating body and the Central vertical axis, and the guest-driven half-coupling mounted on the shaft, rigidly attached to the tower is movable without rotation and has two fixed positions: the lower - inclusion, and the top - off stabilization of the tower.

The design of the CCC with remote control is illustrated by drawings, where: figure 1 is a kinematic diagram of the drive and control mechanism for stabilizing the position of the turret (side view, the right pair of wheels is conventionally rotated by 90°); figure 2 - is a kinematic diagram of the drive rotation of wheel pairs (top view without the body and the upper part of the wheeled platform).

In the design of the CCC with remote control without changes, as a prototype, remain (1, 2): General layout of the wheeled platform 1 with four wheel pairs 2, body 3, tower 4, the supporting rollers 5, a battery, two electric motors to provide movement means 6 and the rotation body 7, the Central gear 8, transmit the Oia with chassis, brake 9, the attenuation of wheels and unit equipment for remote management tool.

Differences between the design of the CCC is shown in figure 1, 2.

The actuator includes a drive rotation body 3 and the wheel 2 pairs.

Changed the drive rotation body 3 (Fig 1) relative to the wheeled platform 1 by changing the location and installation of the driven toothed bevel wheel transmission 11 in the Central gear 8. The rotation of the body 3 relative to the Central vertical axis 10 of the wheeled platform 1 is carried out from the right of the motor 7 through the coupling on the right gear bevel gear 11 of the Central gear 8, the follower wheel which is rigidly connected to the Central vertical axis 10 with the bottom of the chassis of the wheeled platform 1. The leading wheel, circling a stationary follower wheel, rotate the wheel.

Modified and simplified drive rotation of the wheel 2 pairs (1, 2) by replacing the cylindrical gear and chain drives two chain transmission with a transmission ratio of 1:1 and a rigid connection of the leading sprocket 12 with the body 3. Each chain transmission consists of a sprocket 12, the drive circuit 13, a tension device 14 and two driven sprockets 15. Turn all wheelset 2 occurs synchronously and at the same angle as the body 3 when it is rotated about a Central vertical axis of the wheel 10 the platform 1 through the pipe 16, rigidly connected to the horizontal support shaft 17 of the Central gear 8 and with two leading stars 12 chain transmission. The driven sprocket 15 is rigidly connected with the rotary columns 18 and frame cross-axle differentials 19 wheelset 2. If necessary, the movement of the CCC on the two tracks are two of the disconnection mechanism from rotation and fixation of two adjacent wheelset 2, or limitation of the rotation body 3 and the other two driven wheel pairs at an angle of 180° is similar to the design of the CCC with manual control.

Significantly improved and simplified mechanism for stabilizing the position of the turret 4 (figure 1) by replacing the two spur and bevel gears, one driven gear clutch 20. Used the design of the CCC - constant orientation of the chassis of the wheeled platform 1 relative to the cardinal directions in the horizontal plane while maneuvering the CCC. Stabilization of the position of the turret 4 is achieved by combining it with the case of the wheeled platform 1 with the managed gear clutch 20. The leading half coupling rigidly connected with the driven toothed bevel wheel gear 11 of the drive rotation body 3 and the Central vertical axis 10. Driven driven half-coupling mounted on the axis 21, is rigidly connected to the tower 4, the movable bezvremenija and has two fixed positions: the lower of (I) - inclusion, and the upper (II) - off stabilization of the tower 4.

Thus, the proposed simplified design of the drive and control mechanism for stabilizing the position of the turret eliminates the disadvantages of the prototype, which increases the reliability and durability of the work of the CCC.
