Diaphragm type spring clutch

Abstract

The invention relates to a diaphragm type spring clutch. The diaphragm type spring clutch comprises a pressing plate, a clutch cover, a diaphragm, an inner supporting ring, an outer supporting ring and a plurality of diaphragm rivets, wherein the diaphragm rivets are uniformly distributed in the circumferential direction, shoulders are arranged at the left ends of the diaphragm rivets, pointed bulges with tooth tops facing rightwards are arranged on the right end surfaces of the shoulders, concave arc surfaces are arranged on the pointed bulges, the diaphragm rivets are used for sequentially connecting the inner supporting ring, the diaphragm, the outer supporting ring and the clutch cover together from left to right, and the concave arc surfaces on the diaphragm rivets are tightly attached to the inner supporting ring; the diaphragm comprises a diaphragm spring main body and separation fingers which are uniformly distributed on an inner ring of the diaphragm spring main body, and reinforcing ribs which are upwards convex are respectively arranged at the centers of the separation fingers along the radial direction. The diaphragm type spring clutch disclosed by the invention is simple in structure, convenient to assemble, disassemble and maintain, capable of overcoming the defect of large idle stroke of a clutch assembly and reducing a separating force of the clutch assembly, high in production efficiency, low in cost, safe and reliable.

Description

technical field [0001] The invention relates to the field of clutches, in particular to an automobile diaphragm spring clutch. Background technique [0002] The clutch is composed of a friction plate, a spring diaphragm, a pressure plate and a power output shaft. It is arranged between the engine and the gearbox, and is used to transfer the torque stored on the engine flywheel to the gearbox to ensure that the vehicle is transmitted to the gearbox under different driving conditions. The appropriate driving force and torque of the driving wheels belongs to the category of powertrain. The existing diaphragm type automobile clutch is composed of a pressure plate, a clutch cover, a diaphragm, an inner support ring and an outer support ring. The clutch cover is provided with several circumferentially evenly distributed flaps. When installing the inner support ring, the clutch cover is The inner support ring is installed between the clutch cover and the diaphragm by bending the t...

AI Technical Summary

Problems solved by technology

The existing diaphragm type automobile clutch is composed of a pressure plate, a clutch cover, a diaphragm, an inner support ring and an outer support ring. The clutch cover is provided with several circumferentially evenly distributed flaps. When installing the inner support ring, the clutch cover is The inner support ring is installed between the clutch cover and the diaphragm when the tongue is turned and bent, the assembly workload is relatively large, the assembly efficiency is low, the inner support ring is prone to breakage, and the disassembly workload is large

Moreover, the rigidity of the ordinary diaphragm spring separation finger is poor, resulting in a large invalid separation stroke of the clutch assembly, a small lift of the pressure plate, and a large separation force, and the reliability of mechanical properties is low.

At the same time, there are problems such as heavy pedal force, difficult gear shifting, and early failure of the clutch on the whole vehicle
