Abstract

The invention discloses a vehicle inertia table with clutches. The vehicle inertia table comprises a control unit, a front roller group, a rear roller group, a flywheel group, the clutches, a front / rear roller group transmission device and a roller group mobile guide rail, wherein the front roller group is supported on the roller group mobile guide rail of the vehicle inertia table, and the clutches are arranged at main rollers of the front roller group and the rear roller group in a left-right way. When a vehicle slips neutrally, the rotation inertia of a vehicle wheel can be measured according to slipping time corresponding to the moments when left clutches and right clutches of the main rollers are connected and disconnected; when the vehicle slips with shift, rotation inertias of an engine flywheel and four wheels can be measured when the vehicle is at different shifts; and by combining the two processes, the rotation inertia of the engine flywheel can be measured when the vehicleis at different shifts. The vehicle inertia table can be used for measuring the rotation inertia of the vehicle wheel, total rotation inertia of the engine flywheel and the wheels when the vehicle isat different shifts and the rotation inertia of the engine flywheel when the vehicle is at different shifts and has a very good application value.

Description

technical field [0001] The invention relates to the technical field of automobile detection, in particular to a vehicle inertia inspection platform with a clutch. Background technique [0002] The chassis dynamometer needs to simulate the load generated by the acceleration inertia of the vehicle when loading, but how to measure the acceleration inertia of the vehicle, especially the rotational inertia, lacks a fast and effective testing method. [0003] The published invention patent CN106989938A "Loading and Inertia Detection Method for Automobile Dynamics" is a bench test for various types of automobiles on a chassis dynamometer with a relatively large equivalent inertia, using the loading force of the power absorbing device and the inertia of the bench as the load. A measure of instantaneous power at the rated torque point. The disclosed invention patent CN107907345B "Detection method of automobile power inertia bench test" is to use the equivalent inertia of the bench a...
