Description

FIELD OF THE INVENTION The invention relates to a transport engineering, in particular to the design of drives for driving wheels.

The aim of the invention is to improve the controllability in the implementation of the rotation of the vehicle on heavy operating conditions.

Figure 1 shows a pneumohydraulic drive wheel drive diagram, in Figure 2 a diagram of the action of forces during rotation.

Vehicle 1 (FIG. 1) has controllable wheels 2, sensor 3

Sh

The obstacle of a sports vehicle, 3 angles of rotation of the vehicle, gives a signal to an active redistribution that pumps from elastic connection 5 to increasing the left driving wheel to the right wheel (FIG. 2, the control required for resistance).

associated with the device 4, the active redistribution of the working fluid between the elastic links 5 and 6 mounted on the driving wheels 7,. eight.

The role of the device 4 for active redistribution of the working fluid can be performed, for example, by a hydraulic pump 9 together with a hydraulic distributor 10. The role of elastic connections 5, 6 in this drive is performed by hydraulic cylinders 11-14 and pneumohydraulic accumulators 15 and 16. Hydraulic cylinders can be of various types: piston , membrane, moment, etc. The angle of rotation of the vehicle can also be of various types: mechanical, hydraulic, electrical. Hydraulic couplings 17, 18 are used to transfer the working fluid to the rotating wheels 7, 8.

The drive works as follows.

When you turn the vehicle, for example, to the right, you may
