Wheel rim driving hydraulic system with load response

A hydraulic system and wheel-side drive technology, which is applied in the direction of fluid pressure actuators, servo motors, servo motor components, etc., can solve the problems that the moving distance cannot be too far, the moving action time cannot be too long, and the driving cannot be achieved. The road system is simple and reasonable, takes up little space, and prevents idling

Abstract

The invention relates to a wheel rim driving hydraulic system with load response. The wheel rim driving hydraulic system comprises a first oil port, a second oil port, a left driving oil cylinder, a left driving motor, a right driving oil cylinder and a right driving motor, wherein the left driving motor and the right driving motor are connected in series and are connected between the first oil port and the second oil port; the left driving oil cylinder and the right driving oil cylinder are connected in parallel; rodless cavities of the left driving oil cylinder and the right driving oil cylinder are connected to the first oil port; and rod cavities of the left driving oil cylinder and the right driving oil cylinder are connected to the series connection part of the left driving motor andthe right driving motor. The wheel rim driving hydraulic system has a load response function; and in a moving process, force applied to a vehicle tire is increased, pressure applied to the motors isalso increased, and the thrust of the oil cylinders is also increased, so that the motors rotate to drive wheels to rotate, and the phenomenon of slipping caused by insufficient friction force or thephenomenon that the vehicle tire is extruded due to too large thrust of the oil cylinders is avoided.

Description

technical field [0001] The invention relates to the field of hydraulic systems, in particular to a wheel-side drive hydraulic system with load response. Background technique [0002] In the case of vehicles which do not have their own drive, this may be the case for example trailers, motorhomes, boats etc. In order to facilitate the movement and removal of non-driven vehicles in the decoupled state, an electric drive device is generally installed on a vehicle without a drive. This drive device is installed on the outside of the wheel, usually in front of or behind the wheel that the drive unit should drive. in the area. Contact with the wheels of the vehicle in a frictional engagement, and the rotation of the drive unit drives the wheels to rotate. The existing driving devices are all in the form of electric driving, and the driving torque of the electric driving device is relatively small, and the installation space requirement is large. Unable to drive large-tonnage veh...
