Description

Improved single diaphragm clutch

Technical Field

The utility model relates to a separation and reunion derailleur technique specifically relates to a modified single diaphragm clutch.

Background

The window of a torsion spring of the damper used in the single diaphragm clutch is rectangular, the torsion spring is limited by adopting a clamping disc structure, the torsion spring can only do front and back linear motion, the elasticity of the spring is easily damaged, and the service life of the spring is short.

SUMMERY OF THE UTILITY MODEL

The present invention provides a single diaphragm clutch, which changes the motion track of the torsion spring and prolongs the service life of the torsion spring.

The utility model discloses the concrete technical scheme who takes is:

the utility model provides a modified single diaphragm clutch, includes clutch case, driving plate, diaphragm spring, support ring, pressure disk, shock absorber, the shock absorber includes friction disc, bumper shock absorber dish, driven plate hub, driven plate body, torsion spring, wherein, the torsion spring external diameter equals the thickness sum of bumper shock absorber dish, driven plate hub, driven plate body, and a torsion spring window frame is the arc, respectively is equipped with a spring limiting plate about the window, spring limiting plate fixed mounting covers the torsion spring window on bumper shock absorber dish and driven plate body.

Preferably, a certain gap is left when the limiting plate covers the torsion spring window.

Preferably, the limit plate is welded or riveted on the damper disc or the driven disc body.

Preferably, the limiting plate is arc-shaped.

The utility model has the advantages that:

1. compared with the clamping disc structure, the limiting plate of the utility model has simple and rapid working and convenient assembly, disassembly and welding;

2. the limiting plate fixedly guides the torsion spring to move (compress) along the arc-shaped window, so that the damage of force to the elasticity of the spring can be effectively reduced, and the service life of the spring is prolonged;

3. a certain gap is reserved on the limiting plate on the torsion spring window, and heat generated by the operation of clutch parts can be effectively dissipated through the gap.

Detailed Description

To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.

Example 1

An improved single diaphragm clutch is shown in fig. 2 and 3, and comprises a clutch cover 1, a transmission plate 2, a diaphragm spring 3, a support ring 4, a pressure plate 5 and a damper, wherein the damper is specifically improved, the damper is shown in fig. 1 and comprises a friction plate 61, a damper plate 62, a driven plate hub 63, a driven plate body 64 and a torsion spring 65, wherein the outer diameter of the torsion spring 65 is equal to the sum of the thicknesses of the damper plate 62, the driven plate hub 63 and the driven plate body 64, the torsion spring 65 is arranged in a torsion spring window, a frame of the torsion spring window is arc-shaped, spring limiting plates 66 are respectively arranged above and below the window and are arc-shaped, and the spring limiting plates 66 are welded on the damper plate 62 and the driven plate body 64 to cover the torsion spring window.

When the flywheel type engine works, power output by the engine is transmitted to the flywheel, the flywheel transmits the power to the friction plate, the friction plate transmits the power to the driven plate body, the driven plate body obtains the power to drive the torsion spring to rotate, and the torsion spring is compressed and becomes arc-shaped.
