Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of power-assisted auxiliary mechanism of clutch pedal.
Background technology
For the vehicle of manual retaining, power-transfer clutch is the vitals of automobile dynamic system, and it is being undertaken cutting off between power and the driving engine and bonded assembly work.And the most directly operating unit that carries out this work is exactly a clutch pedal, and it is the control member of autoclutch assembly, is automobile and chaufeur " man-machine " interactive portion.In normal driving, clutch pedal is one of vehicle drive " five big controls ", and frequency of usage is very high.
Realize the separation of power-transfer clutch through handling clutch pedal, need clutch pedal to have certain displacement stroke, chaufeur is trampled clutch pedal and is disengaged the clutch; At this moment; Clutch pedal needs return, in order to make the clutch pedal return complete, is connected with boost pump on the general clutch pedal assembly; When boost pump is decontroled clutch pedal at chaufeur, provide power-assisted to make the complete return of clutch pedal.Though but boost pump provides power-assisted when the clutch pedal return, when clutch pedal is stepped on, form resistance also, and clutch pedal step on low more, resistance is big more, thereby causes that clutch pedal tramples not thorough.And when the clutch pedal return, return is high more, and power-assisted is more little, thereby causes that the clutch pedal return is not thorough.This defective makes the clutch pedal operating effort not steady, thereby has influenced the maneuvering performance of automobile.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed a kind of power-assisted auxiliary mechanism of clutch pedal, and it is more complete that the power-assisted auxiliary mechanism of this clutch pedal can make clutch pedal trample with return.
The purpose of the utility model can realize through following technical proposal: a kind of power-assisted auxiliary mechanism of clutch pedal; Comprise pedal support and be hinged on the pedal arm on the pedal support; It is characterized in that; Between pedal support and pedal arm, be provided with torsion spring, an end of this torsion spring is connected on the pedal arm, and the other end is connected on the above-mentioned pedal support.
Torsion spring one end is connected on the pedal support, is connected on the pedal arm after the other end compresses.When pedal arm rotated around its hinge-point, torsion spring one end that is connected on the pedal arm moved thereupon, and torsion spring also moves thereupon, and this torsion spring has a torque direction conversion flex point in moving process.Be operated and stroke is crossed a half at pedal, the moment of torsion of torsion spring is that pedal arm provides a downward power-assisted, make trample lighter, more thorough.When decontroling pedal, pedal arm is done the return rotation and stroke is crossed a half, and the torque direction of torsion spring changes, and for pedal arm provides a restoring force that makes progress, makes that the pedal arm return is more complete.
On pedal arm and the hinged place that is in pedal arm and pedal support be installed with an assister bar.Make torsion spring in the pedal arm rotation process, form the flex point that a torque direction changes through assister bar, the power-assisted of torsion spring passes to pedal arm through this assister bar.
Said assister bar is fixed on the above-mentioned pedal arm through the mode of welding.Assister bar is welded on the pedal arm, need not to design again pedal arm, practices thrift cost.
One end of said torsion spring is hinged on the free end of above-mentioned assister bar.One end of torsion spring is bent into an inside axial pin, and this is axially worn to establish and is hinged on the assister bar, can rotate relative to assister bar.
One end of said torsion spring is hinged on the above-mentioned assister bar free end through a lubricative axle sleeve.Through sheathed lubricative axle sleeve on the axial pin of torsion spring one end, reduce the friction between torsion spring and the assister bar, lubricative axle sleeve is fixed in the hinge hole of assister bar.
The other end of said torsion spring is installed axle sleeve through one and is hinged on the above-mentioned pedal support.The other end of torsion spring also can rotate relative to pedal support, axle sleeve is installed can be made and be connected more firmly between torsion spring and the pedal support, and the two ends of torsion spring all can be rotated; Therefore; In the pedal arm rotation process, torsion spring also can be along with rotation, thereby forms the flex point that a torque direction changes.
Compared with prior art, the power-assisted auxiliary mechanism of this clutch pedal has the following advantages:
1, because pedal arm rotates and through receiving the power-assisted of torsion spring after the half stroke, thus trample lighter, more thorough.
2, because making progress, pedal arm receives the power-assisted of torsion spring after rotation and the process half stroke, so the pedal arm return is more complete.
3, because this auxiliary mechanism realizes that through welding an assister bar and connecting a torsion spring so simple in structure, cost is low.

The specific embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
As shown in Figure 1, a kind of power-assisted auxiliary mechanism of clutch pedal comprises pedal support 3 and pedal arm 2, and pedal support 3 is connected on the vehicle body, and pedal arm 2 is hinged on the pedal support 3, rotates relative to pedal support 3.On pedal arm 2 and the hinged place that is in pedal arm 2 and pedal support 3 be installed with an assister bar 4, both need not to design again pedal arm 2 through being welded to connect, and practice thrift cost.Between pedal support 3 and assister bar 4, be provided with torsion spring 1, an end of torsion spring 1 is installed axle sleeve 6 through one and is hinged on the above-mentioned pedal support 3, can rotate relative to pedal support 3, installation axle sleeve 6 can make between torsion spring 1 and the pedal support 3 be connected more firm.The other end of torsion spring 1 is bent into an inside axial pin; This axial pin is hinged on above-mentioned assister bar 4 free ends through a lubricative axle sleeve 5; Can rotate relative to lubricative axle sleeve 5; Lubricative axle sleeve 5 is fixed in the hinge hole of assister bar 4, and lubricative axle sleeve 5 can reduce the friction between torsion spring 1 and the assister bar 4.Torsion spring 1 forms the flex point that a torque direction changes through assister bar 4 in pedal arm 2 rotation processes.Because the two ends of torsion spring 1 all can relatively rotate, thus at pedal arm 2 when its hinge-point rotates, torsion spring 1 one ends that are hinged on the assister bar 4 move thereupon, torsion spring 1 also moves thereupon, torsion spring 1 has a torque direction conversion flex point in moving process.Be operated and stroke is crossed a half at pedal, the moment of torsion of torsion spring 1 is that pedal arm 2 provides a downward power-assisted, make trample lighter, more thorough.When decontroling pedal, pedal arm 2 is done the return rotation and stroke is crossed a half, and the torque direction of torsion spring 1 changes, and for pedal arm 2 provides a restoring force that makes progress, makes that pedal arm 2 returns are more complete.
Specifically, as shown in Figure 2, the line between the hinge-point of an end of torsion spring 1 and the hinge-point of assister bar 4, assister bar 4 and pedal arm 2, two hinge-points is a critical line.When pedal arm 2 is positioned at a half of its rotational travel, torsion spring 1 is vertical with critical line with assister bar 4 bonded assemblys one end, torsion spring power-assisted F
0Be directly passed to the hinge-point of pedal arm 2 along critical line, the rotation of pedal arm 2 is not produced the power-assisted effect.
As shown in Figure 3, when pedal continues to be operated, and pedal arm 2 rotates a half that surpasses its stroke, and the angle between torsion spring 1 and assister bar 4 bonded assemblys, one end and the critical line is greater than 90 °, torsion spring power-assisted F
