Abstract
The invention discloses a limiting device of a torsional damper of a clutch driven disc for a heavy vehicle. The limiting device comprises an upper cover plate, a lower cover plate, an inner disc hub, an outer disc hub, a damping spring and limiting pins. The upper cover plate and the lower cover plate are respectively provided with six concentric circular holes, six oblong holes are arranged on the outer disc hub, the center of the oblong holes is coincided with the center of the six circular holes on the upper cover plate and the center of the six circular holes on the lower cover plate, the limiting pins penetrate through the oblong holes of the outer disc hub to be mounted in a concentric circle between the upper cover plate and the lower cover plate, and each limiting pin is of a step structure with a thicker middle and two thinner ends. Torsion damping and limiting effects are realized by turning the limiting pins on the oblong holes of the outer disc hub, extract impact higher than extreme torque can be carried, the service life of the torsional damper is prolonged, and accordingly the service life of the driven disc is prolonged.
Description
Technical field
The present invention relates to the automobile clutch technical field.
Background technique
At present; The clutch driven plate torsion damping does not have limit function mostly; Bear the torsional impact beyond the torsion damping by shock-absorbing spring fully, such device will certainly cause the premature damage of shock-absorbing spring and dependency structure, thereby shortens the working life of driven disc vibration damper.
Summary of the invention
Technical problem to be solved by this invention is the deficiency to existing technology, and a kind of clutch driven plate with limit stoper is provided.
For solving this technical problem; The invention provides a kind of heavy goods vehicles and use the clutch-disc damper limit stoper; Comprise upper cover plate, lower cover plate, inner disc hub, coil hub and damping spring outward; Also comprise position limit pin, be respectively equipped with six concentric circle holes on said upper cover plate and the lower cover plate, said outer dish hub is provided with six slotted holes; The center of this slotted hole overlaps with six circular hole centers on upper cover plate and the lower cover plate, and the slotted hole that said position limit pin passes outer dish hub is installed in the concentric circle between upper cover plate and the lower cover plate.
Said position limit pin is middle slightly thick, the slightly thin hierarchic structure in two.
Beneficial effect: the present invention is coiled outside on the hub length circular hole to rotate through position limit pin and is realized torsion damping and position-limiting action, can bear the additional impact beyond the torque limit, prolongs torsional vibration damper working life, thereby prolongs driven disc working life.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of outer dish hub of the present invention.
Among the figure: 1 position limit pin, 2 lower cover plates, 3 shock-absorbing springs, 4 inner disc hubs, 5 outer dish hubs, 6 upper cover plates, 7 slotted holes.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done specific descriptions.
Shown in Figure 1 is structural representation of the present invention.
Fig. 2 is the structural representation of outer dish hub of the present invention.
The present invention includes position limit pin 1, upper cover plate 6, lower cover plate 2, inner disc hub 4, coil hub 5 and damping spring 3 outward.
Be respectively equipped with six concentric circle holes on said upper cover plate 6 and the lower cover plate 2, coil hub 5 outward and be provided with six slotted holes 7, the center of this slotted hole 7 overlaps with six circular hole centers on upper cover plate 6 and the lower cover plate 2.
The slotted hole 7 that said position limit pin 1 passes outer dish hub 5 is installed in the concentric circle between upper cover plate 6 and the lower cover plate 2, leans on the circular hole location of upper cover plate 6 and lower cover plate 2.
Said position limit pin 1 is middle slightly thick, the slightly thin hierarchic structure in two, thereby realizes that position limit pin 1 is connected with lower cover plate 2 perfect rigidities with upper cover plate 6.
The present invention is when free state; Position limit pin 1 is positioned at slotted hole 7 centers of outer dish hub 5, and when shock-absorbing spring 3 was compressed, position limit pin 1 externally coiled hub 5 mutually with upper cover plate 6 and lower cover plate 2 and rotates; When position limit pin 1 is interfered with slotted hole 7 edges; Limit stoper begins to work, and this moment, the moment of torsion on the shock-absorbing spring 3 can not increase again, then the circular hole that coils hub length circular hole 7, upper cover plate 6 and lower cover plate 2 by position limit pin 1, is outward born.
The present invention is coiled outside on the hub length circular hole to rotate through position limit pin and is realized torsion damping and position-limiting action, can bear the additional impact beyond the torque limit, prolongs torsional vibration damper working life, thereby prolongs driven disc working life.
The above-mentioned embodiment of the present invention just illustrates, and is not only, all within the scope of the present invention or the change that is equal in the scope of the present invention all surrounded by the present invention.
Claims (2)
1. a heavy goods vehicles is used the clutch-disc damper limit stoper; Comprise upper cover plate (6), lower cover plate (2), inner disc hub (4), coil hub (5) and damping spring (3) outward; It is characterized in that: also comprise position limit pin (1); Be respectively equipped with six concentric circle holes on said upper cover plate (6) and the lower cover plate (2); Said outer dish hub (5) is provided with six slotted holes (7), and the center of this slotted hole (7) overlaps with six circular hole centers on upper cover plate (6) and the lower cover plate (2), and said position limit pin (1) passes outward that the slotted hole (7) of dish hub (5) is installed in the concentric circle between upper cover plate (6) and the lower cover plate (2).
2. heavy goods vehicles according to claim 1 is used the clutch-disc damper limit stoper, it is characterized in that: said position limit pin (1) is middle slightly thick, the slightly thin hierarchic structure in two.
