Abstract

The invention discloses a stepped n-gear wet clutch structure, which is characterized by comprising a casing, an oil delivery pipe, a piston, a sealing ring, a stop washer, a return spring, a clutch plate, a gear shaft, a gear ring gear and a gear transmission structure, The movement of the piston is controlled by the hydraulic pressure, the return spring accelerates the return speed of the piston, the sealing ring prevents the leakage of hydraulic oil, the stop washer fixes the position of the clutch plate, the gear shafts are all hollow shafts, and are nested layer by layer. Circle solid connection. The structure of the invention has large bearing capacity, good heat dissipation performance and wide application range; the stepped shell design shape saves space and is compact in structure; adopts the concept of modularization, can be extended continuously and has wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of clutch design, in particular to a stepped n-speed wet clutch structure. Background technique [0002] With the development of our country's national economy and the progress of science and technology, the automobile industry has achieved unprecedented rapid development. In the aspect of automobile drive train, wet clutch is a key component of automatic transmission. In-depth research is carried out on its engagement control and dynamic performance of the engagement process. It is of great significance to the development of my country's automobile industry. [0003] At present, there are mainly two types of clutches: wet and dry. For dry clutches, the cost is low and the mechanical transmission efficiency is high. When the dry clutch is used, frequent gear shifting is required. If the heat dissipation is not timely, it will easily cause failure. The wet clutch absorbs heat through the transmission oil, an...
