The adjusting range of characteristic more more stable greatly it is easy to realize crutches point power-assisted, can preferably debug out and meet design requirement
Spring force curve, makes pedal characteristic meet design requirement.
In the boosting mechanism of above-mentioned clutch pedal assembly, described pedal arm has bushing one, described bushing is a set of
On described fixed part, described fixed part is fixed on pedal arm by bushing one.By the design of bushing one, can play slow
Punching acts on, and reduces the abrasion between power-assisted torsion spring and pedal arm, avoids producing abnormal sound simultaneously.
In the boosting mechanism of above-mentioned clutch pedal assembly, described pedal support is additionally provided with two bushings two, described
Fixation is plugged in corresponding bushing two respectively at the two ends of power-assisted torsion spring.The design of two bushings two, can play buffering important,
Decrease the abrasion between power-assisted torsion spring and two ends and pedal support, avoid producing abnormal sound simultaneously.
In the boosting mechanism of above-mentioned clutch pedal assembly, on described pedal shaft, also fixation is arranged with axle sleeve, described steps on
Tight fit between plate arm and axle sleeve.The abrasion being designed between reduction pedal arm and pedal shaft of axle sleeve, it is to avoid produce abnormal sound.
In the boosting mechanism of above-mentioned clutch pedal assembly, described pedal support is additionally provided with upper limit cushion pad and lower limit
Bit buffering pad, described pedal arm can be leant with upper limit cushion pad or lower limit cushion pad by swing.Upper cushion pad and
Lower cushion pad can limit the oscillating stroke of pedal arm, can play preferable cushioning effect, it is to avoid the abrasion of pedal arm simultaneously again.
Compared with prior art, the boosting mechanism of this clutch pedal assembly has advantages below：By adopting power-assisted torsion spring
With the double-spring structure of return torsion spring, be equivalent to two spring effect superpositions, bigger to the adjusting range of spring force characteristics, hold very much
Easily realize crutches point power-assisted, can preferably debug out the spring force curve meeting design requirement, improve the assist characteristic of pedal,
