Plate arm 1, when pedal arm 1 does not rotate i.e. clutch pedal assembly does not work when, the elastic force of torsionspring 7 is equal to the interior of clutch general pump
The power and extension spring 10 that pass to pedal arm 1 is pressed to pass to the returning place force sum of pedal arm 1, so as to ensure that clutch pedal
When assembly does not work, pedal arm 1 is located at initial position (position when i.e. pedal arm 1 does not rotate).
When stepping on pedal, pedal arm 1 rotates around rotary shaft 3, and fixed pin shaft 4 follows pedal arm 1 to move together, and presses
To clutch general pump, power is sent in clutch hydraulic system, now torsionspring is supplied to pedal arm 1 one to help its rotation
Power-assisted, so as to contribute to driver more easily control to use clutch；When unclamping pedal, internal pressure of the pedal arm 1 in clutch general pump
With overcome in the presence of the returning place force of extension spring 10 torsionspring 7 elastic force act under return to initial position.
The clutch pedal assembly that the present invention is provided is consolidated by the anchor point to torsionspring 7 and torsionspring support 8
The restriction of fixed point, it is ensured that torsionspring 7 can constantly apply the power for promoting its rotation to pedal arm 1 when pedal arm 1 rotates,
It efficiently avoid that pedal use feeling is excessively heavy, and the returning place force provided by extension spring 10 pedal arm 1, it is ensured that
Pedal unclamps bumper step arm 1 can return in time.
As shown in Figures 5 to 7, in order to which more easily torsionspring 7 is positioned on pedal support 2, and ensure to reverse
The transmission of the elastic force of spring 7, clutch pedal assembly of the invention also includes the spring installation axle 9 being connected with the pedal support 2,
The first spring arm 71 has the first bending segment 711 extended towards the spring installation axle 9, so, passes through the first spring arm 71
Bending place and spring installation axle 9 cooperation, it is convenient to torsionspring 7 is positioned on pedal support 2.Above-mentioned be connected can lead to
The modes such as welding or bolt connection are crossed to realize.
In order to ensure the stability of the elastic force of torsionspring 7 transmission, the deterioration of the use feeling of pedal, the first spring arm are prevented
71 the second bending segments 712 and the 3rd bending segment 713 including being sequentially connected, wherein, second bending segment 712 is reversed from described
The spring body 73 of spring 7 extends towards the second spring arm 72, and the 3rd bending segment 713 is directed away from the direction of the spring body 73
Extension, and be connected with first bending segment 711.
In order to which more firmly the first spring arm 71 is positioned in spring installation axle 9, first bending segment 711 and described
There is 45 degree of angle (i.e. angle α in Fig. 6) between three bending segments 713.
Further, in order to ensure the elastic force of torsionspring 7 transmission stability, prevent the deterioration of the use feeling of pedal, institute
State the second bending segment 712 parallel with the central shaft of the spring body 73, the 3rd bending segment 713 and first bending segment
711 is in the same plane, and the plane where both (the first bending segment 711 and the 3rd bending segments 713) and the spring body 73
Central shaft it is perpendicular.
In a preferred embodiment of the invention, one end of the torsionspring support 8 is connected with the pedal arm 1,
Gap 81 is provided with the other end of the torsionspring support 8, above-mentioned be connected can be real by modes such as welding or bolt connections
It is existing；
The second spring arm 72 has the 4th bending segment 721 extended towards the first spring arm 71, the 4th bending
Section 721 is engaged with the gap 81, and this set is conducive to that the second spring arm 72 easily is positioned at into torsionspring support 8
On.
Further, in order to prevent torsionspring 7 from distorting, pedal is caused to use unstable, the torsionspring support 8 is
Platy structure, first bending segment 711 and the torsionspring support 8 are in the same plane, the 4th bending segment 721
It is perpendicular with the torsionspring support 8.
Because the elastic force of torsionspring 7 and the internal pressure of clutch general pump may change with the use of clutch,
Therefore, it is also provided with being used to adjust the torsionspring 7 in the torsionspring support 8 on the torsionspring support 8
The adjusting hole 82 of anchor point, the number of above-mentioned adjusting hole 82 and position can be set according to the actual requirements, and the present invention is not to this
Further repeat.
In order to ensure stability that extension spring 10 and torsionspring 7 are used, the center of the spring body of the extension spring 10
Line and the center line of the spring body 73 of the torsionspring 7 are perpendicular.
In order to prevent torsionspring support 8 from being rocked during use, have influence on that clutch pedal assembly uses is steady
It is qualitative, via 61 is provided with the caging bolt support 6, the torsionspring support 8 is passed through from the via 61.
Although the present invention is described with reference to above example, the present invention is not limited to above-described embodiment,
And be only defined by the appended claims, those of ordinary skill in the art easily can modify and change to it, but simultaneously
Without departing from the essential idea and scope of the present invention.
