Abstract

The invention discloses an automobile transmission assembly fatigue life test bench, which relates to the technical field of automobile part manufacturing. The automobile transmission assembly fatiguelife test bench comprises a speed-up box, a speed-up box output end flange, a coupling, a cylinder input end flange, a cylinder assembly and a support assembly, wherein the support assembly comprisesa support body; the support body is provided with a horizontal through hole; the horizontal through hole is internally provided with a sleeve; the sleeve is fixed in the support body through screws;the right end surface of the support body is provided with a cylindrical boss; the boss is connected with a mounting plate with a groove matched with the boss; the cylinder assembly is provided with astepped shaft; and the stepped shaft is fixed in the horizontal through hole through the bearing. The problem of a long bench debugging process at an early stage of the current automobile transmission assembly fatigue life test can be solved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an automobile transmission assembly fatigue life test bench. Background technique [0002] During the fatigue life test of the transmission assembly, the input speed of the driving motor is high and the torque is large, so it is necessary to ensure that the power connection of each component has a good coaxiality, and the coaxiality of the power connection of each component is directly It affects the smooth progress of the fatigue life test of the transmission assembly. Better coaxiality can make the power transmission smoothly. During the test, the vibration and noise of the bench are small; During the test, the bench will vibrate greatly, the noise will be high, and even the test bench will be damaged; the common fatigue life test bench of automobile transmission assembly is as follows: figure 1 As shown, it mainly consists of drive motor, gearbox 1, gearbox o...
