A fast centering and positioning device and method for chassis transmission system testing

Abstract

The invention discloses a quick centering positioning device and a quick centering positioning method for a chassis transmission system test. The quick centering positioning device comprises a test bench base, wherein a longitudinal driving sliding table is arranged on the test bench base, and a longitudinal driving unit is arranged on the longitudinal driving sliding table; by taking the axial line of an output shaft of the longitudinal driving unit as the center, two transverse loading sliding tables and a transverse sliding table driving device used for driving the two transverse loading sliding tables to perform equidistance and synchronous movement in the same or reverse directions are arranged on the test bench base; a loading unit is arranged in the center of each transverse loading sliding table, each loading unit is connected with an output shaft of a rear axle of a tested chassis, and the longitudinal driving unit is connected with an input shaft of the tested chassis. The invention also discloses the quick centering positioning method for the chassis transmission system test. The quick centering positioning device and the quick centering positioning method for the chassis transmission system test can adapt to the width change of rear axles of different series of chassis, so that chassis transmission systems of vehicles such as different tractors can be rapidly mounted, centered and positioned accurately on the test bench in the transmission system test.

Description

technical field [0001] The invention relates to a testing device and method for a chassis transmission system, in particular to a fast centering and positioning device and method for testing a chassis transmission system. Background technique [0002] For some vehicles such as tractors, the transmission chassis is an integral transmission chassis, which consists of four parts: transmission system, driving system, steering system and braking system. The function of the chassis is to support and install the tractor and other vehicle engines and their components and assemblies to form the overall shape of the tractor and other vehicles, and receive the power of the engine to make the tractor and other vehicles move and ensure normal driving. The power from the engine of a vehicle such as a tractor is transmitted to the drive wheels through the transmission system. Among them, the chassis transmission system has functions such as deceleration, speed change, reversing, power int...

AI Technical Summary

Problems solved by technology

The installation and adjustment personnel are required to have high technical proficiency, the installation process is time-consuming and labor-intensive, and the adjustment accuracy may not meet the requirements

If the adjustment accuracy does not meet the requirements, test the eccentricity of the power input shaft of the drive shaft and the chassis, and the eccentricity of the test loading shaft and the output shaft of the chassis; resulting in the following consequences: a small eccentricity may increase the additional load of the motor and increase the vibration of the test bench; eccentricity When it is large, it will increase the motor load and the vibration of the test bench, and may cause damage to the connecting device, damage to the motor overload trip and damage to the chassis transmission system
