The invention relates to the technical field of hydraulic drive, and particularly discloses a novel multi-output-shaft hydraulic drive device. The novel multi-output-shaft hydraulic drive device comprises hydraulic radial plunger motors which are oppositely arranged through connecting pieces. Each hydraulic radial plunger motor comprises a motor shell, swinging cylinder bodies, plungers and an oil distributor, wherein the swinging cylinder bodies are arranged in the motor shell and provided with trunnions, the plungers are located in the swinging cylinder bodies and are in sliding fit with the swinging cylinder bodies, and the oil distributor is located in the corresponding connecting piece and provides high-pressure oil for the swinging cylinder bodies; and the plungers are installed on swinging spherical hinges, and the swinging spherical hinges are installed on output crank shafts through bearings. Each hydraulic radial plunger motor further comprises a synchronization-differential motion control valve for receiving signals. The synchronization-differential motion control valve and the oil distributors are connected through oil conveying pipes, and oil conveying channels are arranged between the oil distributors and the swinging cylinder bodies. When a vehicle needs to turn, the control signals are transmitted to the control valves so that the control valves can be in a differential motion state; and when the vehicle needs to drive linearly or a road surface is slippery, the control valves can be arranged at the synchronization station so that the control valves can be equivalent to differential locks.
Description
technical field [0001] The invention relates to the technical field of hydraulic drive and is suitable for driving vehicles, in particular to a hydraulic drive device with multiple output shafts. Background technique [0002] Traditional hydraulic motors have only one output shaft and can only output power in one direction. When multiple drives are required, multiple motors are required to be assembled together, which takes up a lot of space and the structural layout is limited. Contents of the invention [0003] The purpose of the present invention is to provide a multi-output shaft hydraulic driving device, which is suitable for driving a vehicle and can control different states for vehicle steering and straight driving respectively. [0004] In order to achieve the above object, the present invention adopts the following technical solution: a multi-output shaft hydraulic drive device, including a hydraulic radial piston motor, characterized in that: the hydraulic radia...
