Dry-type dual-clutch hydraulic combination and separation bearing assembly

Abstract

The invention belongs to the technical field of car clutch separation, and relates to a dry-type dual-clutch hydraulic combination and separation bearing assembly, in particular to a dry-type dual-clutch hydraulic combination and separation bearing assembly adopted on a pony car. The dry-type dual-clutch hydraulic combination and separation bearing assembly comprises a first separation bearing, a first piston, a second piston, a cylinder and a second separation bearing. Two coaxially-arranged hydraulic cavities are arranged at one end of the cylinder. The two coaxially-arranged hydraulic cavities of the cylinder are connected with the first piston and the second piston respectively in a sliding mode. The two independent separation bearings and a separation mechanism are combined into a whole, hydraulic force is adopted for alternately pushing the first piston and the second piston to axially slide in a reciprocating mode inside the two axially-arranged hydraulic cavities, the first separation bearing and the second separation bearing are driven to alternately extrude two diaphragm springs to be separated so as to achieve combination and separation of a dry-type clutch, variable speed gear shifting is achieved, the separation mechanism is simplified, the mutual positions are compact, the boundary dimension is small, the weight is low, separation is stable, and no impact noise is generated.

Description

technical field [0001] The invention relates to a dry-type double-clutch hydraulic combination release bearing assembly, in particular to a dry-type double-clutch hydraulic combination release bearing assembly used in a small car, and belongs to the technical field of automobile clutch separation. Background technique [0002] Dual clutch is a kind of transmission mechanism that can transmit power and cut off power. Its function is mainly to ensure that the car can start smoothly, reduce the impact load of the transmission gear and prevent the drive train from overloading when shifting gears. The dry double clutch has two sets of clutches that work alternately with each other, and needs to be equipped with two sets of independent release bearings and release mechanisms. Compared with the traditional single clutch, it has a complex structure, large dimensions, and heavy weight. Therefore, when used in small cars, the relevant parts must be designed more compactly to meet the...

Problems solved by technology

This form of switching gear has the following defects: in the process of frequent gear switching, the separation sleeve slides reciprocally on the shaft sleeve of the gearbox I for a long time, and is extremely easy to wear between each other; the separation fork and the two shift forks on the separation sleeve The supporting surface is in point contact, and the impact noise is large. At the same time, uneven wear easily occurs at the contact point of the supporting surface of the shift fork, resulting in a bad operating feeling and difficulty in shifting gears.
