Description

Technical Field

[0001] The utility model relates to the technical field of transmission test benches, in particular to a flywheel inertia adjustment device for a test bench. Background Art

[0002] Common transmission test benches need to be equipped with flywheels with large inertia for the input or output motor ends. Large inertia flywheels can ensure the stability of the speed, alleviate the impact of torque shock on the motor during gear shifting and other tests, and can also simulate the inertia of the entire vehicle when the transmission is installed on the actual vehicle. However, the large inertia flywheels currently installed on the test benches are almost all fixed inertia and cannot be adjusted. Different transmissions have different rated torques and different matching vehicle masses. The test bench flywheel inertia needs to be adjusted according to actual conditions to be closer to the actual vehicle working conditions.

The slide assembly can be moved forward and backward and fixed under the push and pull of the moving mechanism. The slide assembly is composed of a slide seat, a torque measuring disc, a dual disc, a dual disc shaft, a clamping force sensor, an adjustment seat, a test piece clutch cover assembly, a test piece driven disc and a slide moving mechanism. However, this patent still cannot adjust the inertia according to the structure, and cannot adjust the test bench flywheel inertia according to actual conditions. Therefore, it is urgent to design a variable flywheel group and its inertia adjustment device to quickly and conveniently adjust the rotational inertia of the transmission system.
