Embodiment Construction

[0012] Such as figure 1 As shown, the quadruped robot electric servo hydraulic source of the present invention includes a quantitative gear pump 2 driven by a servo motor 1. The oil outlet of the quantitative gear pump 2 is connected to the inlet of the oil discharge pipe 4, and the middle part of the oil discharge pipe 4 is from front to back An oil discharge pipe check valve 5, a filter 6 and an accumulator 7 are provided in sequence, and the oil discharge pipe 4 is respectively connected with the left front leg oil supply pipe 8, the right front leg oil supply pipe 9, the left rear leg oil supply pipe 10 and the right rear leg oil supply pipe. The oil inlet of the oil pipe 11 is connected; the filter 6 can filter the oil to ensure the cleanliness of the oil in the system.

[0013] The oil supply pipe 8 of the left front leg has 4 oil outlets, and each oil outlet of the oil supply pipe 8 of the left front leg is respectively connected with the P working oil port of a left fr...

Abstract

The invention provides an electric servo hydraulic source of a four-leg robot. The electric servo hydraulic source comprises a quantitative gear pump (2) driven by a servo motor (1), and an oil outletof the quantitative gear pump (2) is connected with an inlet of an oil drainage pipe (4); an oil drainage pipe one-way valve (5), a filter (6) and an energy accumulator (7) are sequentially arrangedin the middle of the oil drainage pipe (4) from front to back; and the oil drainage pipe (4) is connected with oil inlets of a left front leg oil supply pipe (8), a right front leg oil supply pipe (9), a left back leg oil supply pipe (10) and a right back leg oil supply pipe (11). According to the electric servo hydraulic source of the four-leg robot provided by the invention, the weight is light,the effective volume is large, oil supplementation pressure is constant, the endurance mileage is long, noise is low, the service life is long, and performance is stable and reliable.

Description

technical field [0001] The invention relates to an electric servo hydraulic source for a quadruped robot. Background technique [0002] The power sources of quadruped robots are divided into two categories: engines and motors. The disadvantage of the engine as the power source of the robot is that it is noisy, and the disadvantage of the motor as the power source of the robot is its heavy weight and short cruising range. Contents of the invention [0003] The purpose of the present invention is to provide a quadruped robot electric servo hydraulic source with light weight, large effective volume, constant oil supply pressure, long cruising range, low noise, long service life, stable and reliable performance of the quadruped robot electric servo hydraulic source . [0004] The quadruped robot electric servo hydraulic source of the present invention comprises a quantitative gear pump driven by a servo motor, the oil outlet of the quantitative gear pump is connected to the ...
