Automobile flywheel assembly

Abstract

The invention discloses an automobile flywheel assembly comprising a flexible disc, a gear ring and a first mass block. The gear ring is arranged on the periphery of the flexible disc. The first massblock is arranged on the disc body of one side of the flexible disc. According to the automobile flywheel assembly provided by the invention, the mass of the flexible disc is increased through the first mass block so as to increase inertia of the flexible disc, and compared with similar design in the prior art, the automobile flywheel assembly has the advantages that on the premise that the layoutof an engine and a hydraulic torque converter is not changed, and the layout of other related parts is not influenced, rotational inertia is increased, and buffering and vibration abilities of a screw machine are improved. The automobile flywheel assembly provided by the invention is convenient to maintain and manage, meanwhile common materials are adopted, and the automobile flywheel assembly can be manufactured conveniently.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to an automobile flywheel assembly. Background technique [0002] With the development of social economy and industrial technology, the requirements for machining and manufacturing precision of mechanical devices are increasing day by day. [0003] The automotive flexible flywheel assembly is assembled at the end of the engine to provide power input for the gearbox. This flywheel is used with an automatic gearbox. The engine starting ring gear is near the end of the crankshaft, and a hydraulic torque converter is connected to the rear end. The hydraulic torque converter is a non-rigid coupling with liquid as the working medium. The flywheel can ensure a smooth start of the car and attenuate the torsional vibration of the drive train, and is widely used in passenger cars. [0004] In recent years, due to the increasingly fierce automobile competition, reducing manufacturin...

Problems solved by technology

Engine costs account for a high proportion of vehicle costs. At present, OEMs have a large number of four-cylinder engines. If three-cylinder engines are used instead of four-cylinder engines, engine costs will be effectively reduced; The layout and the layout of the hydraulic torque converter are inconvenient to change

The existing solution is: add an additional moment of inertia disk to achieve, but adding an additional moment of inertia disk increases the thickness in the axial direction, which will cause changes in the layout of the existing engine and torque converter, and greatly increase the cost. Increase trial production time and risk
