Problems solved by technology

[0003] The traditional no-load detection work for the assembled gearbox usually only locates the gearbox on the detection mechanism, and then connects the input shaft spline of the gearbox to the docking spline of the driving part of the detection mechanism, and then The gearbox is driven by the drive motor to test the assembly quality and performance of the gearbox under the condition of no external torque. Obviously, the traditional inspection method cannot completely simulate the situation that the gearbox has a flywheel rotating in a real vehicle. The data obtained from the load test is difficult to reflect the real quality and performance indicators of the gearbox no-load test

Abstract

The invention relates to the field of automobile gearbox test, and specifically relates to a gearbox no-load test inertia loading mechanism. The mechanism comprises an inertia flywheel, a translation slide, a drive shaft, a butt joint and a brake mechanism, wherein the inertia flywheel and the drive shaft are mounted on the translation slide, the two sides of the inertia flywheel are equipped with an inertia flywheel shaft, the inertia flywheel shaft on the front side of the inertia flywheel is connected with the drive shaft, the end, away from the inertia flywheel, of the drive shaft is connected with the butt joint, the front end of the butt joint is equipped with an applying pin which is used for being in butt-joint with a gearbox to be detected, the butt joint is driven by the translation slide to move, a spring for buffer is arranged between the drive shaft and the butt joint, the inertia flywheel shaft on the rear side of the inertia flywheel is connected with the brake mechanism, and the inertia flywheel starts or stops rotating under control of the brake mechanism. During no-load test of a gearbox, an external inertia can be applied to the gearbox under test according to actual circumstances.

Description

technical field [0001] The invention relates to the field of automobile gearbox detection, in particular to an inertia loading mechanism for a gearbox no-load test. Background technique [0002] The gearbox is one of the important components of the automobile transmission system, and also one of the most important components in the composition of the automobile. Due to the special importance of the gearbox, there are strict requirements for the performance testing of the gearbox after assembly. After the gearbox is assembled, it is necessary to carry out relevant no-load inspections without external torque. These inspections mainly include noise detection, shift performance detection, odometer sensor detection, reverse gear switch detection, and neutral gear switch detection. and other testing items to ensure the assembly quality of the gearbox. [0003] The traditional no-load detection work for the assembled gearbox usually only locates the gearbox on the detection mechan...
