specific Embodiment 1

[0030] The special equipment driving system of the present invention is mainly applied to wheel-leg composite equipment, that is, engineering equipment including both driving wheels and leg-foot mechanisms.

[0031] The engineering equipment mainly used in the special equipment driving system of this embodiment includes a car body, and the front and rear ends of the car body respectively have a pair of front wheels and a pair of rear wheels. There are three leg and foot mechanisms arranged at the upper interval, that is, a wheel-leg composite equipment with four wheels and six legs. When this kind of composite equipment is in use, the leg-foot mechanism can be folded and retracted so that the wheels touch the ground. It can be used in a manner similar to a traditional vehicle. The leg-foot mechanism can be stretched out to touch the ground and output drive together with the wheels. This is the wheel-leg composite drive mode. Of course, under some usage requirements, the leg-fo...

Abstract

The invention relates to a special equipment driving system. It specifically includes: power module, rear hydraulic drive system and control system; rear hydraulic drive system includes: rear drive hydraulic pump, rear drive hydraulic motor, leg and foot hydraulic actuators and rear drive hydraulic oil circuit; rear drive hydraulic oil circuit includes leg The foot hydraulic oil circuit and the rear wheel hydraulic oil circuit; the leg foot hydraulic oil circuit and the rear wheel hydraulic oil circuit are respectively provided with a switch module, downstream of the switch module, the leg foot hydraulic oil circuit is connected to the rear wheel hydraulic oil circuit and can The rear wheel hydraulic oil circuit supplies energy in one direction; when the rear wheel is driven, the rear drive hydraulic pump directly drives the rear drive hydraulic motor to output torque through the rear wheel hydraulic oil circuit, and then drives the rear wheel to rotate; The oil circuit is cut off, and the rear drive hydraulic pump supplies energy to the rear wheel and the leg and foot hydraulic actuators simultaneously through the leg and foot hydraulic oil circuit. The special equipment driving system of the present invention makes the bearing capacity of the equipment stronger and can adapt to more and wider use requirements.

Description

technical field [0001] The invention relates to a special equipment drive system. Background technique [0002] With the continuous development of equipment manufacturing technology, new types of equipment that can adapt to more use environments and occasions have also emerged one after another. For example, a wheel-leg compound robot disclosed in the Chinese invention patent with application publication number CN112590964A includes two pairs of four driving wheels on both sides of the main body, and six leg-foot mechanisms on the left and right sides and the front and rear ends of the main body. , through the mutual cooperation of the wheels and legs, the wheeled mode, the legged mode and the obstacle surmounting mode can be realized. However, this kind of wheel-leg composite equipment is driven by electricity, and its carrying capacity is poor, and its performance is poor in some harsh environments such as low temperature on plateaus and dangerous mountains.
