Abstract

The invention discloses a double-mass flywheel for a double-clutch automatic speed changer. A convex and a concave springs are arranged between a main flywheel body and an auxiliary flywheel body of the double-mass flywheel, power output teeth are arranged in the middle part of a middle disc (41) of a middle disc assembly of the double-mass flywheel, the middle disc is provided with a convex spring cover (412) for assembling an idle speed shock absorption spring of the middle disc assembly, the concave teeth of a middle disc cover (42) of the middle disc assembly adopts a sawtooth shaped structure, the short teeth of the sawtooth shaped structure are of an n-shaped teeth structure (421), and the long teeth (422) tilt to form an upward slope shape. According to the flywheel, torsional oscillation and resonance of a transmission system caused by fluctuation of an engine torque at an idle speed and in a common working condition are avoided, noise of the speed changer and a vehicle body is eliminated, and comfort of the taking is remarkably improved. Meanwhile, power input teeth and the power input teeth of a double-clutch cover assembly are enabled to be maintained in a certain connection status to realize compensation function, the abrasion gap which is unrecoverable caused by hard contact connection between teeth is effectively overcome, and the performance and the use effect of a product is improved.

Description

technical field [0001] The invention relates to an automobile clutch, in particular to a dual-mass flywheel of a dual-clutch automatic transmission. Background technique [0002] The clutch is an important part in the automobile transmission system. It is mainly composed of a flywheel, a clutch cover assembly, a driven disc assembly, a release bearing, a pressing mechanism and an operating mechanism. Its important function is to ensure reliable torque transmission. [0003] With the continuous improvement of human living standards and the vigorous development of the automobile industry, higher requirements are put forward for the comfort of vehicle operation. In particular, the advent of dual-clutch automatic transmission (DCT), a high-end product characterized by improving comfort, fuel consumption and emissions, has significantly improved driving comfort, and the unprecedented smoothness can be improved under driving conditions. Fuel efficiency and reduced CO2 emissions. ...
