Description
Technical field
The utility model relates to a kind of elastic member, particularly a kind of power assistant spring of clutch.
Background technique
Along with the application of torquey engine on passenger car increases, there is passenger vehicle engine moment of torsion even to reach 350Nm～400Nm.The in the situation that of limited space, the moment of torsion that needs clutch compressing disc to provide very high impacting force could transmit motor, in this case, the Separating force of clutch is inevitable very high, and the very high meeting of Separating force causes pedaling force very high, the travelling comfort that impact is driven.Therefore, need to design a kind of power assistant spring and reduce Separating force under the prerequisite that guarantees clutch torque transmission capacity.
Model utility content
Technical problem to be solved in the utility model is that a kind of power value characteristic of utilizing belleville spring will be provided, and reduces Separating force in the situation that not affecting impacting force.
In order to solve above technical problem, the utility model provides a kind of power assistant spring of clutch, and this power assistant spring is a belleville spring, and it is stuck between clutch cover and diaphragm spring, and the shirt rim of belleville spring is inclined to cone angle gradually by interior radial outer diameter.
The internal diameter of described power assistant spring is provided with a plurality of radially slotted eyes, and external diameter is provided with a plurality of and breach support rivet Spielpassung, the displacement axially and radially of constraint power assistant spring.
Described breach is uniformly distributed on the external diameter of power assistant spring.
The working principle of clutch is to utilize diaphragm spring to produce impacting force, thereby transmitting torque, in the time of will cutting off moment of torsion transmission, for overcoming impacting force, thereby utilize lever principle to produce Separating force, so Separating force is produced by impacting force.Utilize the power value characteristic of power assistant spring just can realize under the prerequisite that guarantees impacting force and reduce Separating force.
Superior effect of the present utility model is:
1) utilize the power value performance curve of power assistant spring, can in the situation that not affecting impacting force, reduce certain Separating force; 2) lower Separating force can reduce the pedaling force on car load, improves the travelling comfort of driving.

Embodiment
Refer to shown in accompanying drawing, the utility model will be further described.
As Figure 1-Figure 5, the utility model provides a kind of power assistant spring of clutch, and this power assistant spring 5 is a belleville spring, and it is stuck between clutch cover 1 and diaphragm spring 6, and the shirt rim of belleville spring is inclined to cone angle gradually by interior radial outer diameter.
As shown in Fig. 2-Fig. 7, the internal diameter of described power assistant spring 5 is provided with a plurality of radially slotted eyes 51, and external diameter is provided with a plurality of and breach 52 support rivet 4 Spielpassung, the displacement axially and radially of constraint power assistant spring.Support ring 3 is stuck between diaphragm spring 6 and support rivet 4.
On the external diameter of described power assistant spring 5, be uniformly distributed nine breach, every 40 °, a breach 52 be just set.Each breach 52 is to form at one section of R=7.5mm arc of two sections of R=8mm arc intermediate light slips, and breach 52 tops are 73.5 ± 0.2mm from the central point distance of power assistant spring.
On the internal diameter of described power assistant spring 5, be uniformly distributed nine slotted eyes 51, every 40 °, a slotted eye 51 be just set.The end of slotted eye 51 is circular arc, circular arc R=3.5mm; The width of slotted eye 51 is 8mm+0.5mm.The internal diameter of power assistant spring is evenly equipped with nine slotted eyes 51, is that the pretightening force of power assistant spring on diaphragm spring separation finger contributes to improve the height difference between 18 separation fingers of diaphragm spring because every two slotted eyes just in time cover the adjacent separation finger of diaphragm spring.
The material of described power assistant spring is C75S DIN EN10132-4, expects thick 0.8mm, by mould punching and heat treatment, is formed.
Height difference on axial between power assistant spring 5 internal-and external diameters has determined the size of cone angle.As shown in Figure 3, the height difference between power assistant spring 5 internal-and external diameters on is axially 4.5 ± 0.2mm, and establishing cone angle is α, α=arcsin[height difference 4.5/ (external diameter 155-contacts internal diameter 114)], releasing cone angle is 9 °～10 °.
As shown in Figure 8, clutch cover 1, support ring 3, support rivet 4, diaphragm spring 6 and power assistant spring 5 are riveted and formed in an operation by support rivet 4.These parts are placed from bottom to top according to the order of support rivet 4, support ring 3, diaphragm spring 6, power assistant spring 5, clutch cover 1 successively, and the head that support rivet 4 is contacted with clutch cover 1 flattens the assembling that completes power assistant spring 5.
Power assistant spring 5 its shirt rim when free state is to be certain cone angle, and when being assembled to assembly, power assistant spring 5 is stuck in the centre of diaphragm spring 6 and clutch cover 1, the cone angle compressed (as Fig. 6) of power assistant spring 5, power assistant spring 5 becomes plain film, produces power value, has retrained axial deformation.Fig. 6 and Fig. 7 have described the kinematic relation of power assistant spring and diaphragm spring, in clutch diaphragm spring 6 deformation processes, diaphragm spring 6 separation fingers move to the left, power assistant spring 5 is to free state distortion (as Fig. 7), clutch diaphragm spring 6 returns in the process of original state, diaphragm spring 6 moves to the right, and power assistant spring 5 is again compressed.
As shown in Figure 9 and Figure 10, by two figure contrasts, can be found, power assistant spring 5 can reduce maximum separation power about 200N.By adjusting cone angle, thickness, the internal-and external diameter equidimension of power assistant spring 5, to meet different clutches, for difference, reduce the demand of Separating force.
Above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any technical solutions of the utility model content that do not depart from, any simple modification of above embodiment being done according to technical spirit of the present utility model, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
