Friction pair system of double clutch

Abstract

The invention discloses a friction pair system of a double clutch. The friction pair system is characterized in that a friction material is adhered onto one surface of the steel disc bracket of each of friction plates, and the other surface of the steel disc bracket of each of the friction plates is a smooth surface; the friction plates are arranged and mounted on one side of a dual disc in sequence; all the surfaces, where the friction materials are mounted, of the friction plates directly face one side of the dual disc; and the steel disc bracket of a previous friction plate is in contact with the friction material of the last friction plate, and heat generated by friction among the components is dissipated. According to the friction pair system of the double clutch, the heat dissipationeffect of the clutch is effectively optimized, and the clutch is prevented from losing effectiveness due to the excessive temperature; meanwhile, the heat dissipation burden on the dual disc, the friction plates and the steel disc brackets is reduced, the design thickness of the friction pair system is reduced correspondingly, the axial length of the clutch is reduced, and the arrangeability of the clutch is obviously improved.

Description

technical field [0001] The invention relates to a clutch of a motor vehicle transmission system, in particular to a friction pair system used in a double clutch structure. Background technique [0002] In the field of dual clutch configurations for motor vehicle drive trains, a friction pair system in which friction plates 2 are arranged at intervals in a plurality of dual plates 1 is usually used, such as figure 1 , figure 2 As shown, the number of dual plate 1 is one more than that of friction plate 2. The counter sheet 1 is a mating friction element 202 with a steel sheet structure providing a contact surface for friction. The friction plate 2 is based on the steel plate bracket 201, with friction elements 202 pasted with black friction material on both sides. The driven speed torque generated by friction completes the transmission of power from the engine to the gearbox. Because the friction and sliding surfaces are outside the friction material 202 on both sides of...

Problems solved by technology

[0003] The object of the present invention is to provide a new type of friction pair system for improving the poor heat dissipation of the clutch. The steel plate bracket of the friction plate of the system can simultaneously absorb the heat generated by the friction surface slipping, so that the clutch friction pair system can be better. Heat dissipation effect, provide more reliable clutch function and effectively prolong the service life of the clutch
