Technical Field
The invention relates to an automobile driving device, in particular to a hydraulic four-wheel driving device.
Background
At present, the existing automobile driving device mostly adopts a two-wheel driving device, the driving power of the two-wheel driving device is small, and the requirement of high-power operation cannot be met; most of automobile driving systems are electric, pneumatic and oil-electricity mixed, the system load capacity is small, and the dust resistance and the interference resistance are weak.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a hydraulic four-wheel drive device which can meet the requirements of high-power operation and lower walking speed.
The technical scheme of the invention is as follows: the motor output end is connected with the input end of the duplex gear pump, one path of the duplex gear pump is connected with the hydraulic motor, the output end of the hydraulic motor is connected with the input end of the speed reducer through the first coupler, the front axle is connected with the output end of the speed reducer through the third coupler, and the rear axle is connected with the output end of the speed reducer through the second coupler, so that the aim of advancing and retreating of the whole vehicle is fulfilled; the other path of the duplex gear pump is connected with the input end of the steering cylinder, and the steering cylinder controls the steering of the whole vehicle through the steering pull rod.
The invention has the beneficial effects that: the load capacity and the dust resistance and the interference resistance of the whole vehicle are greatly enhanced. The device is suitable for occasions with short-distance reciprocating flexible task execution, heavy load and severe dust environment.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Fig. 2 is a P-direction view of fig. 1.
Fig. 3 is a schematic structural diagram of the present invention after hiding the motor and the dual gear pump.
