Problems solved by technology

Although the synchronous driving method can increase the traction force of the vehicle when driving, when the vehicle is in a field environment with complex working conditions, it will cause the vehicle to walk on uneven roads, because the paths traveled by each wheel at the same time are different. The same, causing one or several wheels to slip, reducing the traction efficiency of the vehicle
[0004] There are also cumbersome hydraulic servo valve control methods, such as the T4 hydraulically driven and co

Embodiment Construction

[0020] Embodiments of the present invention are described below with reference to the accompanying drawings:

[0021] figure 1 Middle: On the actual vehicle, the electromagnetic reversing valve 3, the diverter 5, the double variable plunger pump 9, the engine 8, and the manual pilot valve 7 are respectively fixed on the frame; the wheel hydraulic motor 1 is installed on the wheel hub ; Duplex variable plunger pump 9 is connected to the engine through a coupling; flow divider 5, electromagnetic reversing valve 3, wheel hydraulic motor 1, and manual pilot valve 7 are connected through hydraulic pipelines.

[0022] The double-connected plunger variable pump converts the mechanical energy provided by the engine into hydraulic energy, and the output flow of the pump is evenly distributed to the wheel side hydraulic motor through the electromagnetic reversing valve through the flow divider, and then the hydraulic energy is converted into mechanical energy through the motor, providin...

Abstract

The invention relates to a full-hydraulic wheel multi-motor independent-drive system, in particular to the application shunt and hydraulic resistance control technology to realize a system for traction balance drive control for each wheel of a full-hydraulic vehicle. A full-hydraulic multi-wheel independent-drive traction balance control system comprises an engine, a duplex variable piston pump, a manual pilot valve, an electromagnetic reversing valve and in-wheel hydraulic motors; the hydraulic elements are connected through hydraulic pipelines; the system is characterized by further comprising a shunt (5) and a throttling device (4); the shunt (5) is fixed on a vehicle frame; the inlet of a hydraulic loop is connected with the duplex variable piston pump (9), and the outlet is connected with the in-wheel hydraulic motors (1) on one side through the electromagnetic reversing valve (3) respectively; and the throttling device (4) is installed between adjacent in-wheel hydraulic motors (1) at the outlet of the shunt (5).

Description

technical field [0001] The invention relates to a full-hydraulic wheel-side multi-motor independent drive system, in particular to a system that uses a flow divider and hydraulic resistance control technology (throttle device) to realize the balanced drive control of the traction force of each wheel of a full-hydraulic vehicle. Background technique [0002] The mobile machinery with a good hydraulic drive system, under the condition of using a smaller power engine, has improved productivity and reduced fuel consumption compared with purely mechanical transmission and hydraulic transmission models, and the labor intensity of operators has also been greatly reduced; Compared with the same power mechanical transmission transmission device, it is lighter in weight and smaller in size, and has a large transmission range, which can realize stepless transmission; flexible installation layout, easy to change the driving system; and can use the hydraulic transmission system to achieve...
