Abstract

The embodiment of the invention discloses a vibration damper and a speed changer, which relate to the technical field of power transmission systems, and are invented for solving the problem that the existing vibration damper has high technical difficulty. The vibration damper is pressed in an input shaft of the speed changer, and comprises a base body and an elastic part; the elastic part covers the surface of the base body; and the elastic part is in interference fit with spline teeth of the input shaft of the speed changer to form an interference part. The vibration damper is applied to the automobile speed changer.

Description

technical field [0001] The invention relates to the technical field of power transmission systems, in particular to a vibration damping device and a transmission. Background technique [0002] Mechanical transmission is widely used in various industrial fields. However, during the transmission process, different degrees of torsional vibration (referred to as torsional vibration) usually occur. It not only affects the normal power transmission, but also has adverse effects on the running comfort and noise control of the overall vehicle. [0003] For example, for the transmission system of an automobile, the power of the engine needs to be transmitted to the driving wheels of the vehicle through the transmission, and the crankshaft of the engine and the input shaft of the transmission are generally engaged with each other through splines to realize power transmission. Due to the vibration of the engine, the crankshaft of the engine will produce torsional vibration, and the in...
