Abstract
The utility model discloses a wear-resistant diaphragm spring which comprises a diaphragm spring body. The wear-resistant diaphragm spring is characterized in that a protection device is mounted at the end of a release finger of the diaphragm spring body and provided with a friction seat, a center hole is arranged in the friction seat, a wedge groove is arranged on an inner ring surface of the center hole, a connecting sleeve extending outwards is mounted in the wedge groove, one side of the connecting sleeve is provided with a beveled edge clamped into the wedge groove, the other side of the connecting sleeve is provided with an outer folded edge extending outwards, the end of the release finger of the diaphragm spring body is positioned between the friction seat and the outer folded edge of the connecting sleeve, and an elastic disc is further mounted between the folded edge of the connecting sleeve and the release finger of the diaphragm spring body. The manufacturing requirement of the diaphragm spring is lowered, the end of the release finger of the diaphragm spring is effectively prevented from wearing, comprehensive performances of the diaphragm spring and a release bearing are improved, the service life is greatly prolonged, and the diaphragm spring is mainly used for an automobile clutch.
Description
Technical field
The utility model relates to the component technical field of automobile diaphragm spring clutch, especially a kind of wear-resisting type diaphragm spring.
Background technique
Diaphragm spring clutch generally is by release bearing pulling or promotes driving that diaphragm spring realizes clutch and separate; traditional diaphragm spring does not arrange any protective gear; the separation finger ends of diaphragm spring directly contacts with release bearing; usually cause the separation finger ends of diaphragm spring to be subjected to inordinate wear, directly influenced usability and the working life of clutch.Therefore, a kind of wear-resisting type diaphragm spring that can address the above problem well of design is very to be necessary.
Summary of the invention
The purpose of this utility model be exactly to solve traditional diaphragm spring directly with release bearing contact cause diaphragm spring separate the finger tip serious wear, problem such as usability is relatively poor and working life is short, a kind of wear-resisting type diaphragm spring is provided.
Concrete scheme of the present utility model is: improve at traditional diaphragm spring, it includes the diaphragm spring body; It is characterized in that: the separation finger ends of described diaphragm spring body is equipped with protective gear; this protective gear has the friction seat; have mesopore in the friction seat; have wedge slot on the inner ring surface of mesopore; the connecting sleeve of outside stretching, extension is housed in the wedge slot; this connecting sleeve one side is provided with the hypotenuse that is stuck in the wedge slot; opposite side is provided with the outer flanging of outside stretching, extension; the separation finger ends of diaphragm spring body between the outer flanging of friction seat and connecting sleeve, the outer flanging of connecting sleeve with the elasticity video disc also is housed between the finger separating of diaphragm spring body.
The key groove α of wedge slot described in the utility model is 60 °.
The utility model has installed protective gear additional in the separation finger ends of diaphragm spring, avoided the separation finger ends of diaphragm spring directly to contact with release bearing, brought following benefit: 1. because the separation finger ends of diaphragm spring no longer directly contacts with release bearing, make the manufacturing of shape, run-out tolerance and hardness of separation finger tip of diaphragm spring require all to have reduced; The separation finger tip that 2. can prevent diaphragm spring is worn, and has improved the working life of diaphragm spring; 3. improved the performance that engages of diaphragm spring with release bearing, using effect is more desirable.
Description of drawings
Fig. 1 is plan view of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: 1-diaphragm spring body, 2-separate and to refer to, 3-protective gear, 4-rubs, 5-wedge slot, the hypotenuse of 6-connecting sleeve, 7-connecting sleeve, 8-mesopore, the outer flanging of 9-connecting sleeve, 10-elasticity video disc.
Embodiment
Referring to Fig. 1 and Fig. 2, the utility model includes diaphragm spring body 1; Particularly: the separation finger ends 2 of described diaphragm spring body 1 is equipped with protective gear 3; this protective gear 3 has friction seat 4; have mesopore 8 in the friction seat 4; have wedge slot 5 on the inner ring surface of mesopore 8; the key groove α of wedge slot 5 is 60 °; the connecting sleeve 7 of outside stretching, extension is housed in the wedge slot 5; these connecting sleeve 7 one sides are provided with the hypotenuse 6 that is stuck in the wedge slot 5; opposite side is provided with the outer flanging 9 of outside stretching, extension; the separation of diaphragm spring body 1 refers to that 2 end is between the outer flanging 9 of friction seat 4 and connecting sleeve; the outer flanging 9 of connecting sleeve also is equipped with elasticity video disc 10 with separating between the finger 2 of diaphragm spring body 1, has namely constituted the utility model.
Claims (2)
1. a wear-resisting type diaphragm spring includes the diaphragm spring body; It is characterized in that: the separation finger ends of described diaphragm spring body is equipped with protective gear; this protective gear has the friction seat; have mesopore in the friction seat; have wedge slot on the inner ring surface of mesopore; the connecting sleeve of outside stretching, extension is housed in the wedge slot; this connecting sleeve one side is provided with the hypotenuse that is stuck in the wedge slot; opposite side is provided with the outer flanging of outside stretching, extension; the separation finger ends of diaphragm spring body between the outer flanging of friction seat and connecting sleeve, the outer flanging of connecting sleeve with the elasticity video disc also is housed between the finger separating of diaphragm spring body.
