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 detection, in particular to a gearbox no-load test inertia loading mechanism, including an inertia flywheel, a translation slide, a transmission shaft, a butt joint and a braking mechanism, wherein the inertia flywheel and the transmission shaft are installed On the translation slide table, inertia flywheel shafts are provided on both sides of the inertia flywheel, wherein the inertia flywheel shaft on the front side of the inertia flywheel is connected to the transmission shaft, and the end of the transmission shaft away from the inertia flywheel is connected to the The butt joint is connected, and the front end of the butt joint is provided with an application pin for docking with the gearbox to be tested, and the butt joint is driven to move by the translation slide table, and a buffer is provided between the transmission shaft and the butt joint The spring used, the inertia flywheel shaft on the rear side of the inertia flywheel is connected with the brake mechanism, and the inertia flywheel is controlled to start and stop by the brake mechanism. The present invention can apply external inertia to the gearbox under test according to the actual situation when the gearbox is subjected to no-load test.

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...
