A kind of clutch pressure plate structure of the present invention, comprise cover plate, pressing plate and diaphragm spring, between described cover plate and described pressing plate, there is cavity, described diaphragm spring is located in described cavity, the middle part of described pressing plate is provided with center hole, described diaphragm spring is connected with described pressing plate by a dish-shaped supporting ring, and described diaphragm spring is between described pressing plate and described dish-shaped supporting ring, described pressing plate is provided with Cheng “ ∟ " shape overhead structure, described overhead structure comprises the supporting portion extended in described cavity by the edge of the center hole of described pressing plate, the limited part extended to the direction of the central axis away from described center hole by the end of described supporting portion, described supporting portion is through described dish-shaped supporting ring and described diaphragm spring, and described dish-shaped supporting ring and described diaphragm spring are all between described pressing plate and described limited part, described dish-shaped supporting ring comprises in trumpet-shaped dish-shaped supporting ring body, the two ends of described dish-shaped supporting ring body have opening, the less one end of described dish-shaped supporting ring body upper shed is towards described limited part, the larger one end of described dish-shaped supporting ring body upper shed is towards described diaphragm spring, the less one end of described dish-shaped supporting ring body upper shed is provided with the in-flanges that the central axis to described dish-shaped supporting ring body extends, one end that the upper shed of described dish-shaped supporting ring body is larger is provided with outward extending flanging, described flanging is close to described diaphragm spring, described flanging is evenly provided with oil storage tank in the plane of described dish-shaped supporting ring, described supporting portion is provided with the groove with described in-flanges tabling.
Further, described cover plate is provided with the lug boss at the edge that can withstand described diaphragm spring.
Further, described pressing plate is provided with the scrobicular ring of a circle to described cavity sunken inside, and described scrobicular ring is conflicted on described diaphragm spring.
Further, described oil storage tank is made up of two groups of cross one another oil grooves.
Owing to have employed said structure, clutch pressure plate assembly of the present invention decreases kind and the quantity of part; The performance of clutch pressure plate assembly can be increased substantially, particularly can improve the lift of clutch pressure plate assembly; The force value of dish-shaped supporting ring is controlled in required scope, not only can overcome the Separating force of diaphragm spring and the pressure of diaphragm spring and pressing plate pretension, and in use the frictional damping between diaphragm spring and pressing plate can be controlled in very little scope, be equivalent to the impacting force that improve clutch pressure plate assembly, that is suitably can reduce the thickness of diaphragm spring under the prerequisite ensureing identical clutch pressure plate assembly impacting force, thus reduce cost of production; The working life of clutch pressure plate assembly can also be increased substantially in addition, wherein overhead structure is formed by riveting process, to reach the object of installing diaphragm spring and dish-shaped supporting ring, and in overhead structure, be provided with groove, groove carries out spacing to dish-shaped supporting ring, in the spacing reference of riveting process further groove as riveting die set, preventing diaphragm spring from riveting tension affects and clutch performance.Pressing plate, diaphragm spring can be pressed on together by butterfly support ring, and can play compensating action after pressing plate, diaphragm spring wearing and tearing, so butterfly support ring can eliminate clutch use loosening of occurring between long period rear film spring and pressing plate; Butterfly support ring arranges flanging coordinate with diaphragm spring, enlarge active surface, flanging is provided with oil storage tank, runs off to prevent lubricant oil, flanging can strengthen elasticity and can reduce the wearing and tearing between butterfly support ring and diaphragm spring, increases the service life further.
