The utility model comprises a wave sheet (1), a friction sheet (5), a holding disc (7), a damp disc (8), and a disc hub (13), a damping disc (19), a damping spring (3,4,16), a rivet (2,6), a limit pin (20), and a damp compacting sheet (10) as well as a disc spring (11, 15) and a damping spring spacer (17) and a nylon compacting sheet (18); wherein the damp disc (8) is provided with a spring window (81), while the limit pin (20) is the flat block shape, and a plurality of limit slots (82) are evenly arranged on the edge of the damp disc(8); wherein the limit slots (82) are provided with a concave port (83) in the middle part and matched with the limit pin (20). The utility model can be applied to the automobile clutch field.

Description

The pre-vibration damping driven disc in the big drift angle of clutch

Technical field

The utility model relates to the pre-vibration damping driven disc in the big drift angle of a kind of clutch.

Background technique

Automobile clutch is the vitals of transmission system.Being used in the driven disc of the pre-vibration damping structure of existing clutch band that damping tray is rotated the drift angle, to play the position limit pin of position-limiting action be cylindrical, and its sectional area is bigger.In order to cooperate with position limit pin and to avoid the spring window, guarantee the intensity of damping tray simultaneously, the restraining groove central angle at existing damping tray outer rim place can not be excessive, caused the deflection angle of driven disc less like this, and the moment of torsion of Chuan Diing is less simultaneously.

The model utility content

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides the big drift angle of clutch that a kind of deflection angle is big, moment of torsion is big pre-vibration damping driven disc.

The technological scheme that the utility model adopted is: the utility model comprises corrugated sheet, friction plate, clamping disk, damping tray, dish hub, damping disk(-isc), shock-absorbing spring, rivet, position limit pin, damping fin, damping clamping piece, belleville spring, shock-absorbing spring pad, nylon clamping piece, described damping tray is provided with the spring window, described position limit pin is the flat bulk, described damping tray outer rim is provided with circumferentially uniform restraining groove of some edges, described restraining groove middle part is provided with recess, and described restraining groove and described position limit pin are suitable.

Described restraining groove and described spring window respectively have four, and described restraining groove and described spring window are in circumferential interlaced arrangement.

Described position limit pin is flat an of cross.

The beneficial effects of the utility model are: because position limit pin described in the utility model is the flat bulk, described damping tray outer rim is provided with circumferentially uniform restraining groove of some edges, described restraining groove middle part is provided with recess, described restraining groove and described position limit pin are suitable, minor face by described position limit pin matches with described restraining groove, described restraining groove and the end face that described position limit pin card ends are reduced than existing product at radial dimension, thereby can avoid described spring window, promptly also can there be described restraining groove at the outer rim place of described spring window central angle correspondence, thereby the deflection gap between described limiting stopper and the described damping tray is strengthened, the deflection angle of described damping tray is strengthened, and then make moment of torsion increase, the intensity that guarantees described damping tray simultaneously meets the demands, avoided the existence of existing cylindrical position limit pin to make restraining groove can not be positioned at the drawback at the outer rim place of spring window central angle correspondence, so the utility model damping tray deflection angle is big, the moment of torsion that transmits during work is big, can satisfy multiple driven disc drift angle and torque demand;

Because restraining groove described in the utility model and described spring window respectively have four, described restraining groove and described spring window are in circumferential interlaced arrangement, such structure has guaranteed the intensity of described damping tray, so the utility model can strengthen deflection angle under the situation that damping tray intensity does not reduce, improve moment of torsion;

Because position limit pin described in the utility model is flat an of cross, described position limit pin is easy to assembly, so the utility model is easy to assembly.
