Problems solved by technology

[0005] Although the dual-mass flywheel can play a very good role in the operation of the vehicle, there is a situation that, in the bench test of some engines before leaving the factory, especially in the cold start and hot start of the engine In the test, it is possible to require the two mass bodies of the dual mass flywheel to remain rigidly connected to verify the specific working conditions of the engine

Abstract

The invention relates to a dual-mass flywheel, comprising a primary mass body, a secondary mass body and a detachable connecting device, wherein the connecting device rigidly connects the primary mass body and the secondary mass body in an installed state . Through the detachable connection device, the primary mass body and the secondary mass body can be rigidly connected during, for example, the engine bench test, and after the bench test is completed, the connection device is disassembled to restore the dual mass flywheel to normal The working condition meets the requirements of the engine test.

Description

technical field [0001] The present invention relates to a dual-mass flywheel, and in particular to a dual-mass flywheel capable of detachably and rigidly connecting a primary mass body and a secondary mass body. Background technique [0002] Usually, the rear end of the engine of the vehicle is provided with a flywheel, which is made of cast steel, has a certain quality, and is fixed on the rear end face of the crankshaft of the engine with engine bolts, and is provided with teeth on its outer periphery to communicate with the starter. The gears etc. are meshed to drive the crankshaft to rotate and start. The flywheel not only works when the engine starts, but also stores and releases energy after the engine starts to improve the uniformity of engine operation, and at the same time transmits engine power to the clutch. [0003] However, this traditional flywheel has certain limitations, that is, the natural frequency between the engine and the transmission cannot be reduced...
