Abstract
The utility model discloses a diaphragm spring of a pull-type diaphragm spring clutch of a heavy vehicle, which solves the problem that the clutch separate pull ring is easy to get away from the diaphragm spring. The diaphragm spring can effectively lead the separate pull ring to be fixed with the diaphragm spring together, and thus causes the clutch not to fail due to the falling off of the separate pull ring or the attenuation of diaphragm spring force value when the diaphragm spring works normally. The structure thereof is as follows: the diaphragm spring comprises a circular diaphragm spring, the small end of which is provided with a spring separate finger device; the shape of the spring separate finger device is matched with that of the external part of the separate pull ring; one side of the big end of the diaphragm spring is an extruded fillet and the other side is a chamfer angle of the vehicle; and the positive surface and the negative surface of the window are extruded fillets.
Description
Technical field
The utility model relates to the pull-type diaphragm spring clutch diaphragm spring of a kind of heavy-duty car.
Background technique
At present, the problem that pull-type diaphragm spring clutch exists is that the draw ring that connects release bearing and diaphragm spring is deviate from from diaphragm spring, and the too early decay of diaphragm spring power value, thereby causes clutch to lose efficacy.
Summary of the invention
The purpose of this utility model is exactly in order to solve the problem that the clutch separation draw ring is deviate from easily from diaphragm spring, provide a kind of heavy-duty car pull-type diaphragm spring clutch diaphragm spring, it can be effectively be fixed together with diaphragm spring separating draw ring, makes it can draw ring is not deviate from or the decay of diaphragm spring power value causes the clutch inefficacy because of separating in proper functioning.
For achieving the above object, the utility model adopts following technological scheme:
The pull-type diaphragm spring clutch diaphragm spring of a kind of heavy-duty car, it comprises the circular film spring, and described diaphragm spring small end is provided with spring and separates finger device, and spring separates the finger device shape and separates the draw ring outside and be complementary; Big end one side of diaphragm spring is the extruding fillet, and opposite side is the car chamfering, and the window tow sides are the extruding fillet.
Described spring separates finger device and is divided into three long separation according to not isometric principle and refers to that group is separated with three weak point and refer to group, and each long separation refers to organize and separates the finger group with weak point and distribute alternately; Wherein each short separation refers to that group has refer to two short separation, and three groups have six short separation and refer to that they are spacedly distributed along circumference; Refer to that group has six long separation to refer to each long separation, and three groups have 18, and each of every group refers to be spacedly distributed to each other long the separation.
Interval between described each adjacent separation refers to is 5mm.
The utility model is in the design of diaphragm spring, with the small end of diaphragm spring with separate the part that draw ring is connected and be optimized processing, diaphragm spring separates and refers to according to not isometric principle and engage the surface of separating draw ring design, diaphragm spring is increased with the contact area that separates draw ring, in the whole using process of clutch, can not cause draw ring from diaphragm spring, to deviate from; Cylindrical turning, big end one side of diaphragm spring extruding fillet, another sidecar chamfering, window tow sides extruding fillet avoids the stress of diaphragm spring in proper functioning to concentrate, and effectively prevents situations such as the power value decay of diaphragm spring or fracture.
The beneficial effects of the utility model are, in proper functioning, can be fixed together with diaphragm spring separating draw ring effectively, make it can draw ring is not deviate from or the decay of diaphragm spring power value causes the clutch inefficacy because of separating in proper functioning.
Description of drawings
Fig. 1 is that separation of the present utility model refers to structure situation;
Fig. 2 is a cross-section structure situation of the present utility model.
Refer to 1. long separation among the figure, refers to 2. short the separation, 3. window tow sides extruding fillet, 4. car chamfering, 5. extruding fillet.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
In Fig. 1, in the design of diaphragm spring, diaphragm spring separates and refers to according to not isometric principle and engage the surface of separating draw ring design, six short separates and refers to that 1 is divided into three groups and separates with three group leaders and to refer to 2 (totally ten eight long separation refer to, per six is one group) distribute alternately, diaphragm spring is increased with the contact area that separates draw ring, in the whole using process of clutch, can not cause draw ring from diaphragm spring, to deviate from.
In Fig. 2, the diaphragm spring cylindrical turning, the big end one side extruding of diaphragm spring fillet 5, opposite side is a car chamfering 4, and window tow sides extruding fillet 3 is arranged at the window place, and window tow sides extruding fillet 3 specifications are R2-3, gap between adjacent separation refers to remains on about 5mm, very convenient to the installation of diaphragm spring like this, and can avoid the stress of diaphragm spring in proper functioning to concentrate, effectively prevent situations such as the power value decay of diaphragm spring or fracture.
