Quadruped robot electroservohydraulic source drive system

Abstract

The quadruped robot electric servo hydraulic source drive system includes a quantitative gear pump, the oil outlet of the quantitative gear pump is connected to the inlet of the high-pressure oil pipe, and the outlet of the high-pressure oil pipe is connected to the inlet of the left oil supply pipe and the inlet of the right oil supply pipe; There is a left hydraulic pump in series on the oil supply pipe, the outlet of the left oil supply pipe is connected with the inlet of the left overflow pipe and the left booster oil pipe, the left overflow valve is connected in series in the middle of the left overflow pipe, and the outlet of the left booster oil pipe is connected with the inlet of the left booster oil pipe. The oil inlet of the left front leg oil supply pipe is connected with the oil inlet of the right rear leg oil supply pipe; the right hydraulic pump is connected in series on the right oil supply pipe, and the outlet of the right oil supply pipe is connected with the outlet of the right overflow pipe and the right booster oil pipe. The inlet is connected, the middle part of the right overflow pipe has a right overflow valve in series, and the outlet of the right booster oil pipe is connected with the oil inlet of the right front leg oil supply pipe and the oil inlet of the left rear leg oil supply pipe. The purpose is to provide a quadruped robot electro-servo hydraulic source drive system with light weight, large effective volume, constant oil supply pressure, long cruising range, low noise, long service life, stable and reliable performance.

Description

technical field [0001] The invention relates to an electric servo hydraulic source drive system for a quadruped robot. Background technique [0002] The drive system of existing quadruped robot can be divided into two categories based on the difference of the power source, which is driven by the engine alone and driven by the motor alone. The disadvantage of only relying on the engine as the power source of the robot is high energy consumption, low efficiency, and high noise; the disadvantage of completely using batteries and motors as the power source of the robot is that the driving motor needs to have a lot of power, which leads to battery life. And the motor is very heavy and the cruising range is short. Contents of the invention [0003] The purpose of the present invention is to provide a quadruped robot electric servo hydraulic source drive system with light weight, low energy consumption, constant oil supply pressure, long cruising range, low noise, long service l...
