Bent axis type plunger hydraulic pump/motor

Abstract

The invention discloses a bent axis type plunger hydraulic pump / motor. The bent axis type plunger hydraulic pump / motor comprises a casing, an end cover, a rear cover, a motor main shaft, a mandrel, a plunger component, a cylinder body and a valve plate, wherein the end cover and the rear cover are fixed at the front end of the casing and the rear end of the casing, the motor main shaft, the mandrel, the plunger component, the cylinder body and the valve plate are installed inside the casing, one end of the motor main shaft extends out of the end cover, a ball socket disk is arranged at the other end of the motor main shaft, one end of the mandrel and one end of the plunger component are arranged inside the ball socket disk respectively, the other end of the mandrel is arranged inside a mandrel hole at the center of the cylinder body, the other end of the plunger component is arranged inside a plunger hole of the cylinder body, the rear cover contacts with the valve plate, the rear cover is provided with an inner cavity, a driving mechanism which is connected with the valve plate is arranged inside the inner cavity, and the valve plate is driven by the driving mechanism to move along the contact surface of the rear cover. The valve plate is driven by the driving mechanism to move along the rear cover, so that the pouring amount angle of the valve plate is changed, and the output volume can be adjusted, that is, the larger the pouring amount angle is, the higher the output volume is.

Description

technical field [0001] The invention belongs to a hydraulic pump / motor, in particular to an inclined-axis plunger hydraulic pump / motor. Background technique [0002] Inclined-axis plunger hydraulic pump / motor is mainly used for hydraulic drive of walking machinery. The traditional inclined-axis plunger hydraulic pump / motor mainly includes a casing, which is fixed on the front and rear ends of the casing, and the rear cover. The motor shaft, mandrel, plunger parts, cylinder body and distribution plate inside the housing; one end of the motor shaft protrudes from the end cover, and the other end is provided with a ball-and-socket plate, and one end of the mandrel and plunger parts is respectively set in the ball-and-socket In the disc, the other end of the mandrel is connected with the distribution plate, and one end of the plunger part is arranged in the cylinder body. The hydraulic pump / motor adopting the above structure has the advantages of simple processing of the plunge...

AI Technical Summary

Problems solved by technology

However, due to the fixed connection between the valve plate and the rear cover, the existing oblique-axis plunger hydraulic pump / motor cannot realize the corresponding adjustment of its displacement.
