Description

Clutch cover assembly for compensating maximum load and minimum load of diaphragm spring

Technical Field

The utility model belongs to the technical field of automobile clutch and specifically relates to a clutch case assembly of compensation diaphragm spring maximum load and minimum load.

Background

The clutch is a device for transmitting power or playing a role in cutting off between an engine and a gearbox of a vehicle, the driven disc is abraded due to frequent use of the clutch, the load of the clutch is increased when the driven disc is excessively abraded, simultaneously, the pedal force is increased, and for a vehicle with larger engine power, if the difference between the maximum load and the minimum load of a diaphragm spring of the clutch is increased, the fall is excessively large when the pedal is stepped, and the pedal feeling of a driver is influenced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a clutch case assembly of the biggest load of compensation diaphragm spring and minimum load can compensate diaphragm spring's biggest load and minimum load difference.

The purpose of the utility model is realized through the following technical scheme:

a clutch cover assembly for compensating the maximum load and the minimum load of a diaphragm spring comprises a clutch cover, a pressure plate, the diaphragm spring and a buffer piece, wherein the clutch cover is arranged on the pressure plate, the inner end of the spring of the diaphragm spring extends into a position between the clutch cover and the pressure plate, and a buffer piece is arranged between the inner end of the spring and the clutch cover.

The buffer piece is made of rubber.

And a buffer supporting piece is arranged between the inner end of the diaphragm spring and the clutch cover, and the buffer piece is arranged in the buffer supporting piece.

The buffer support piece is concave, the clutch cover is provided with jacks, two sides of the buffer support piece are respectively inserted into the corresponding jacks, and the buffer piece is arranged in a notch of the buffer support piece.

The utility model discloses an advantage does with positive effect:

1. the utility model discloses be equipped with the bolster between clutch case and diaphragm spring, the bolster is tensile or the compression plays the cushioning effect between diaphragm spring and clutch case when starting the footboard to can compensate the biggest load of diaphragm spring and minimum load difference.

2. The utility model discloses the drop is too big when avoiding the pedal, effectively improves the sensation that the driver stepped on the pedal.

figure 2 is a cross-sectional view of the embodiment of figure 1,

figure 3 is a schematic structural view of another embodiment of the present invention,

figure 4 is a cross-sectional view of the embodiment of figure 2,

fig. 5 is a schematic view of a drop compensating load curve of the present invention.

The clutch cover comprises a diaphragm spring 1, a spring inner end 101, a spring outer end 102, a clutch cover 2, a lower convex portion 201, a limiting ring 202, a stud 203, a buffer piece 3, a pressure plate 4, a pressing sheet 401, a buffer supporting piece 5 and an inserting hole 6.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1-4, the utility model discloses a clutch case 2, pressure disk 4, diaphragm spring 1 and buffer 3, clutch case 2 is located on pressure disk 4, and the inner 101 of spring of diaphragm spring 1 stretches into between clutch case 2 and the pressure disk 4, and be equipped with buffer 3 between the inner 101 upside of spring and the clutch case 2. The utility model discloses the during operation, the similar lever of diaphragm spring 1 can make diaphragm spring 1's spring outer end 102 receive decurrent power after the footboard starts to make diaphragm spring 1's spring inner 101 rebound and remove the pressure to pressure disk 4, this is the well-known technique in the field, the utility model discloses set up bolster 3 between diaphragm spring 1's spring inner 101 and clutch case 2 and play the cushioning effect, thereby can compensate the biggest load of diaphragm spring and minimum load difference.

As shown in fig. 2 and 4, a lower protrusion 201 and a stud 203 are arranged on the clutch cover 2, a stop collar 202 is arranged on the lower side of the stud 203, and the diaphragm spring 1 passes through the lower protrusion 201 and the stop collar 202 to realize a lever effect.

As shown in fig. 2 and 4, the pressure plate 4 is provided with a pressing plate 401 having an upper protrusion, and the lower side of the spring inner end 101 of the diaphragm spring 1 abuts against the upper protrusion of the pressing plate 401.

The buffer parts 3 are made of rubber, the rubber is EPDM (ethylene Propylene diene monomer), and a plurality of buffer parts 3 can be uniformly distributed along the circumferential direction of the clutch cover 2 at equal intervals.

As shown in fig. 1 to 2, the buffer member 3 may be directly provided between the spring inner end 101 of the diaphragm spring 1 and the clutch cover 2.

As shown in fig. 3 to 4, a buffer support 5 may be provided between the spring inner end 101 of the diaphragm spring 1 and the clutch cover 2 to prevent the buffer member 3 from being worn, the buffer support 5 is concave, the clutch cover 2 is provided with a plurality of insertion holes 6, two sides of the buffer support 5 are respectively inserted into the corresponding insertion holes 6, the buffer member 3 is disposed in the recess of the buffer support 5, and the buffer support 5 prevents the buffer member 3 from being worn and also prevents the buffer member 3 from being separated due to the centrifugal force.

The utility model discloses the theory of operation does:

the utility model discloses the during operation, the similar lever of diaphragm spring 1 can make diaphragm spring 1's spring outer end 102 receive decurrent power after the footboard starts to make diaphragm spring 1's the inner 101 rebound of spring and remove the pressure to pressure disk 4, the utility model discloses set up bolster 3 between diaphragm spring 1's the inner 101 of spring and clutch case 2, the bolster is tensile or the compression plays the cushioning effect between diaphragm spring and clutch case when starting the footboard, thereby can compensate the diaphragm spring maximum load and minimum load difference, the drop is too big when avoiding the pedal, effectively improves the sensation of pedal when the driver drives. The utility model discloses specific compensation effect is seen in fig. 5, wherein the condition of load curve one for not adopting bolster 3, and the condition of load curve two for adopting bolster 3, and the difference of maximum load and minimum load obviously diminishes.
