According to the clutch pedal erecting by overhang of the utility model one not shown embodiment, comprise: clutch pedal; The clutch pedal arm, it is connected with described clutch pedal, and is arranged between initial position and maximum trampling position, to rotate around a fulcrum; And power assistant spring, the first end of described power assistant spring is fixed, the second end is connected with described clutch pedal arm, and described clutch pedal arm is applied to elastic force, when described clutch pedal arm is in described maximum trampling position, described power assistant spring applies the trampling assist torque to described clutch pedal arm.Wherein, described power assistant spring can be extension spring, can be also stage clip.
Clutch pedal erecting by overhang of the present utility model adopts power assistant spring to reduce clutch pedal power, has characteristics simple and reliable for structure.And solved limitations and the high problem of treadle effort improving cost that the clutch maneuvering system is arranged.
Fig. 1 is the installing condition schematic diagram according to the clutch pedal erecting by overhang of the utility model one embodiment.Fig. 2 is another schematic diagram of the erecting by overhang of clutch pedal shown in Fig. 1, for clarity sake, has omitted the parts such as pedal base.
Clutch pedal erecting by overhang as shown in Figure 1-2 comprises: clutch pedal 6; Clutch pedal arm 1; Power assistant spring 10; Pedal pivotal axis 5; Power assistant spring lower bracket 8; Power assistant spring pilot bar 11; Rotating axle bushing 13; Upper support support 2; Lower support support 3 and pedal base 4.Upper support support 2; Lower support support 3 and pedal base 4 are for supporting whole clutch pedal erecting by overhang.Power assistant spring pilot bar 11 is for guiding the direction of power assistant spring.The lower end of power assistant spring pilot bar 11 and power assistant spring lower bracket 8 are hinged, and power assistant spring lower bracket 8 is fixedly attached to clutch pedal arm 1.The upper end of power assistant spring pilot bar 11 and rotating axle bushing 13 are hinged, and rotating axle bushing 13 is fixing with respect to upper support support 2.The upper end of power assistant spring 10 is against rotating axle bushing 13, lower end abutment power assistant spring lower bracket 8.
One end of clutch pedal arm 1 is connected with clutch pedal 6, and is arranged between initial position (position shown in Fig. 1) and maximum trampling position (position shown in Fig. 2), to rotate around pedal pivotal axis 5, thereby realizes clutch function.
The first end of power assistant spring 10 (and the upper end in Fig. 1 and Fig. 2) is fixing, and the second end is connected with described clutch pedal arm, and described clutch pedal arm is applied to elastic force.Be understandable that, in this patent, the first end of power assistant spring 10 is fixing, and not to refer to that first end is completely fixed motionless, and refer to that the point of action of the first end of power assistant spring 10 fixes.In fact, along with the rotation of clutch pedal arm, the angle of the first end of power assistant spring or change towards meeting.Also it is pointed out that in this patent, the second end clutch pedal arm of power assistant spring 10 is connected, and refers to that the second end of power assistant spring and clutch pedal arm are in transmission connection, to elastic force of clutch pedal arm effect.In the embodiment shown in Fig. 1-2, power assistant spring 10 is stage clips.
At the initial position shown in Fig. 1, a conter clockwise torque of 10 pairs of clutch pedal arms of power assistant spring, 1 effect, thereby as pull back spring.In the maximum trampling position shown in Fig. 2,10 pairs of clutch pedal arms of power assistant spring 1 act on a clockwise torque (trampling assist torque), thereby can reduce the pedal force of chaufeur, and now power assistant spring 10 is as the trampling power assistant spring.A midway location place between described initial position and maximum trampling position at described clutch pedal arm, the center conllinear of the direction of the elastic force of power assistant spring 10 and pedal pivotal axis 5, the torque of 10 pairs of clutch pedal arms 1 of power assistant spring is zero, and this midway location can be called the free suspension position.
When the clutch pedal arm is between described initial position and free suspension position, power assistant spring applies aligning torque to described clutch pedal arm, thereby can save original special-purpose pull back spring; When the clutch pedal arm is between free suspension position and maximum trampling, power assistant spring provides the trampling assist torque, can reduce required clutch trampling power.That is to say, do not need special-purpose pull back spring just can realize the effect of pedal return and trampling power-assisted simultaneously.
Advantageously, the angle between described initial position and described free suspension position is less than or equal to the angle between described free suspension position and described maximum trampling position.
Angle between described initial position and described free suspension position is less than or equal to 20 degree and is more than or equal to 5 degree, for example 5 degree, 10 degree, 15 degree or 20 degree or other suitable angles.
Preferably, described clutch pedal erecting by overhang further comprises the vapour-pressure type clutch booster be in transmission connection with described clutch pedal arm.
Described clutch pedal erecting by overhang can be applied to vehicle, particularly is applied to middle heavy card.
Fig. 3 a-3c is the schematic diagram that the situation of the elastic force that the clutch pedal erecting by overhang of another embodiment of the utility model bears in initial position, free suspension position and maximum trampling position is shown.
In Fig. 3 a, clutch pedal arm AB is in initial position, and the power assistant spring first end is against the D point of the arm CD be connected with clutch pedal arm AB, and the other end is against attachment point P.The direction of elastic force now is as shown in arrow F1.Elastic force now produces anticlockwise moment, for making clutch pedal arm AB return.
In Fig. 3 b, clutch pedal arm AB rotates to the free suspension position from initial position (position shown in dotted line Fig. 3 b) around fulcrum O.In the free suspension position, arm CD has also rotated to position shown in Fig. 3 b, and now the direction of elastic force is as shown in arrow F2, and through fulcrum O, thereby the moment that elastic force produces is zero.
In Fig. 3 c, clutch pedal arm AB further rotates to maximum trampling position around fulcrum O from the free suspension position.In maximum trampling position, arm CD has also rotated to position shown in Fig. 3 c, and now the direction of elastic force is as shown in arrow F3.Elastic force now produces clockwise moment, for reducing required clutch trampling power.
Fig. 4 illustrates the utility model schematic diagram of clutch pedal erecting by overhang situation of elastic force when initial position, free suspension position and maximum trampling position of an embodiment again.In this embodiment, it is upper that an end of pull back spring acts directly on clutch pedal arm AB, and the other end acts on attachment point.When initial position, free suspension position and maximum trampling position, the direction of elastic force is respectively as shown in arrow F1, F2 and F3.
Finally it is to be noted: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit.Although with reference to previous embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: its technical scheme that still can put down in writing aforementioned each embodiment is modified, perhaps part technical characterictic wherein is equal to replacement (for example, adopt extension spring to replace the stage clip in above-described embodiment---now need to change the position of attachment point); And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
