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. The special equipment driving system specifically comprises a power module, a rear hydraulic driving system and a control system; the rear hydraulic driving system comprises a rear-drive hydraulic pump, a rear-drive hydraulic motor, a leg and foot hydraulic execution component and a rear-drive hydraulic oil way; the rear-drive hydraulic oil way comprises a leg and foot hydraulic oil way and a rear wheel hydraulic oil way; the leg and foot hydraulic oil way and the rear wheel hydraulic oil way are each provided with a switch module, and the leg and foot hydraulic oil way is connected with the rear wheel hydraulic oil way and can supply energy to the rear wheel hydraulic oil way in a one-way mode on the downstream portions of the switch modules; when the rear wheels are driven, the rear-drive hydraulic pump directly drives the rear-drive hydraulic motor to output torque through the rear-wheel hydraulic oil way, and then the rear wheels are driven to rotate; and during wheel-leg combined driving, the rear wheel hydraulic oil way is cut off, and the rear-drive hydraulic pump supplies energy to the rear wheels and the leg-foot hydraulic execution component at the same time through the leg-foot hydraulic oil way. According to the special equipment driving system, the bearing capacity of the equipment is higher, and the special equipment driving system 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.
