All-electric four-axis periodic cycle test bench and experimental method

Abstract

The invention discloses an all-electric four-axis periodic cycle test bench and a test method, comprising a base, two left transverse guide rails arranged on the left part of the base, two right transverse guide rails arranged on the right part of the base, The left sliding base on the upper part, the right sliding base on the right part of the base, the left arc magnetic track and the left arc guide rail on the left sliding base, the right arc magnetic track and the right arc on the right sliding base Guide rail, the left swing base connected with the left arc magnetic track and the left arc guide rail, the right swing base connected with the right arc magnetic track and the right arc guide rail, the left gear box arranged on the left swing base, located on the right Swing the right gearbox on the base. The invention has the characteristics of high motor transmission efficiency, little influence on the motor by load changes, and high stability of the direct drive motor system.

Description

technical field [0001] The invention relates to the technical field of test benches, in particular to an all-electric four-axis periodic cycle test bench with energy recovery function, good stability, small footprint and convenient maintenance and an experimental method. Background technique [0002] The speed universal joint is an important part in the transmission system of a car. Its function is to transmit the power of the engine from the transmission to the driving wheel of the car to meet the requirements of the outer end of the drive shaft of the car; to transmit the power of the engine to the wheels smoothly and reliably. ; Compensate the beating of the suspension at the inner end of the car. Drive the car at high speed. Thus, a test bench conforming to the "Automobile Industry Standard of the People's Republic of China" QC / T 1020-2015 was born. [0003] Existing technology: adopt mechanically closed structure (commonly known as square machine), hydraulic continuou...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the invention is to overcome the low hydraulic transmission efficiency and large energy consumption of the test bench in the prior art; the hydraulic system is less stable due to the influence of oil temperature and load changes; the pressure system occupies a large area and the daily maintenance is cumbersome In order to solve the shortcomings, an all-electric four-axis periodic cycle test bench and experimental method with energy recovery function, good stability, small footprint and convenient maintenance are provided.
