Electric servo hydraulic power source drive system of four-foot robot

Abstract

An electric servo hydraulic power source drive system of a four-foot robot comprises a quantitative gear pump. The oil outlet of the quantitative gear pump is connected with the inlet of a high-pressure oil pipe. The outlet of the high-pressure oil pipe is connected with the inlet of a left oil supply pipe and the inlet of a right oil supply pipe. The left oil supply pipe is connected with a left hydraulic pump in series. The outlet of the left oil supply pipe is connected with the inlet of a left overflow pipe and the inlet of a left supercharging oil pipe. The middle of the left overflow pipe is connected with a left overflow valve in series. The outlet of the left supercharging oil pipe is connected with the oil inlet of a left front leg oil supply pipe and the oil inlet of a right rear leg oil supply pipe. The right oil supply pipe is connected with a right hydraulic pump in series, and the outlet of the right oil supply pipe is connected with the inlet of a right overflow pipe and the inlet of a right supercharging oil pipe. The middle of the right overflow pipe is connected with a right overflow valve in series. The outlet of the right supercharging oil pipe is connected with the oil inlet of a right front leg oil supply pipe and the oil inlet of a left rear leg oil supply pipe. According to the purpose, the electric servo hydraulic power source drive system of the four-foot robot is light, large in effective volume, constant in oil supplementing pressure, long in driving mileage, low in noise, long in service life, and stable and reliable in 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...
