Problems solved by technology

However, in the prior art, the hydraulic oil needs to enter the oil cavity of the balance piston first. When the oil cavity of the balance piston is filled, part of the hydraulic oil enters the oil cavity of the friction plate group. The hydraulic oil is not filled in time, causing the friction plate The temperature rises and most of the hydraulic oil flows away through the gaps in the automatic transmission, resulting in hydraulic oil waste

Abstract

The invention relates to the technical field of automatic transmissions, and provides a starting clutch for a transmission. The starting clutch comprises a piston device and a friction device. The friction device comprises a friction plate set, an inner hub and an outer hub. An oil cavity is formed between the inner hub and the friction plate set. The piston device comprises a main piston and a balance piston, and a balance piston cavity is formed between the main piston and the balance piston. The main piston is arranged on a piston support. The piston support is provided with an oil supply part, an oil supply channel is formed in the oil supply part, a sealing steel sleeve is arranged on the inner side of the piston support, and the sealing steel sleeve is provided with a sealing part. When oil is supplied, part of hydraulic oil enters the balance piston cavity through a first oil way, the other part of the hydraulic oil directly enters the oil cavity of the friction plate set, and the supplementing efficiency of the hydraulic oil is improved; the sealing steel sleeve extends to the inner side of the oil supply part, and a first sealing element is arranged, so that the hydraulicoil is prevented from flowing away from the gap of the clutch, and waste of the hydraulic oil is avoided; and meanwhile, the oil supply amount of the friction plate set is ensured.

Description

technical field [0001] The invention relates to the technical field of automatic transmissions, in particular to a starting clutch for a transmission. Background technique [0002] The automobile transmission is a set of speed change devices used to coordinate the engine speed and the actual driving speed of the wheels, and is used to exert the best performance of the engine. The transmission can generate different gear ratios between the engine and the wheels during the running of the car, and realize the transmission of different gear speeds. [0003] The transmission is divided into manual and automatic. The manual transmission is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations; while the automatic transmission AT is composed of a hydraulic torque converter, a planetary gear and a hydraulic control system. Power transmission and gear combination to achieve variable speed and torque. [0004] Among ...
