Double-spring structure clutch pedal servomechanism, including pedal support, pedal arm, pedal, pedal is hinged by pedal arm and pedal support, and dual spring resistance gauge is provided between pedal arm and pedal support, and pedal arm power-assisted of dual spring resistance gauge in rotary course gradually increases；Due to the stiffness variation of dual spring cause spring force will not sharpness decay, therefore pedal power-assisted will not sharpness decay, reduce the pedal force that customer tramples, improve the comfortableness that client's pedal is trampled, the problem of efficiently solving the decay of pedal power-assisted sharpness.

Description

Double-spring structure clutch pedal servomechanism

Technical field

The utility model patent belongs to a kind of double-spring structure clutch pedal, especially a kind of double-spring structure clutch Pedal servomechanism.

Background technology

With Global Auto industrial expansion and growth in the living standard, requirement of the people to car comfort is increasingly Height, it requires that pedal can realize the change of spring rate during trampling, and avoids driver in pushes pedals to lower dead center position Put pedal power-assisted sharpness attenuation problem.Current most of clutch pedal power assistant springs are using single torsion spring, torsion spring, compression bullet Spring, the change of spring rate, thus pedal pedal when down stroke will be trampled can not be realized during pedal is trampled The shortcomings that sharpness decay be present in power-assisted.

The content of the invention

The purpose of this utility model is to provide a kind of double-spring structure clutch pedal servomechanism, the mechanism solve from Clutch pedal will trample at final position the problem of pedal power-assisted sharpness decays in pedal.

In order to solve the above-mentioned technical problem, the technical solution of the utility model is：Double-spring structure clutch pedal power-assisted Mechanism, including pedal support, pedal arm, pedal, pedal are hinged by pedal arm and pedal support, it is characterised in that：Pedal arm Dual spring resistance gauge is provided between pedal support；The dual spring resistance gauge is by spring conductor rod, spring fairlead, big bullet Spring, center base, little spring are formed, and front end and the pedal arm of spring conductor rod are hinged, tail end and the pedal branch of spring conductor rod Frame is hinged, and spring fairlead, big spring, center base, little spring are set gradually from front to back on spring conductor rod, wherein greatly Spring and little spring are slidably connected in compressive state, spring fairlead and center base and spring conductor rod.

Beneficial effect：The utility model compares Single spring structure pedal, because the stiffness variation of dual spring causes spring force Will not sharpness decay, therefore pedal power-assisted will not sharpness decay, reduce the pedal force that customer tramples, improve client's pedal The comfortableness trampled, efficiently solve the problem of pedal power-assisted sharpness decays.

Embodiment

As shown in Figure 1, Figure 2 and Figure 3, double-spring structure clutch pedal servomechanism, including pedal support 1, pedal arm 2nd, pedal 3, the tail end of pedal arm 2 are provided with clutch pump installation bearing pin 201, pedal shaft 202, pedal arm upper pin 203, pedal The tail end of arm 2 is hinged with pedal support 1 by pedal shaft, and pedal 3 is fixed on the front end of pedal arm 2；Pedal arm and pedal Dual spring resistance gauge 4 is provided between support, dual spring resistance gauge is by spring conductor rod 401, spring fairlead 402, big spring 403rd, center base 404, little spring 405 are formed, and front end and the pedal arm 2 of spring conductor rod 401 pass through pedal arm upper pin 203 Be hinged, pedal support 1 is provided with pedal support upper pin 101, and tail end and the pedal support 1 of spring conductor rod 401 pass through pedal Support upper pin 101 is be hinged, and spring fairlead 402, big spring 403, center base 404, little spring 405 are on spring conductor rod Set gradually from front to back, wherein big spring and little spring are oriented in compressive state, spring fairlead and center base and spring Bar is slidably connected.

As shown in Figure 4 and Figure 5, job description：1）Setting：Pedal centre initial position is C1, pedal travel position be C2, C3, pedal centre final position are C4, and pedal shaft center is O, are corresponded in pedal arm upper pin during initial pedal position Heart position A1, pedal travel to C2, C3 corresponds to pedal arm upper pin center A2, A3 respectively, when pedal is in final position Corresponding pedal arm upper pin center A4, pedal support upper pin center B；2）Pedal is inverse in C1 initial positions, pedal Hour hands rotate, and when turning to C2 by C1, pedal arm upper pin moves to A2 around pedal shaft O by A1, and two springs are to pedal arm The direction of upper pin A1 active forces is 2 points of B-A1 extended line direction, and A1 points move around O points, and big spring is limited by center base Position, little spring are limited between center base and spring conductor rod tail end after compressing certain distance, and now small spring force is more than big Spring spring force, big spring are not worked, and center base is not subjected to displacement with respect to big spring, in the triangle of 3 points of compositions of O, A1, B In, A1 and B distance are minimum, and the elastic force of little spring is maximum, and two springs produce clockwise moment to pedal arm upper pin, now Two springs produce returning place force effect to pedal；When pedal travel to C2 positions, A1 points move to A2, and now A2 is in 2 points of O and B Line on, two springs are BO directions to pedal arm bearing pin force direction, and the arm of force zero, now pedal force is zero.3）When Pedal rotates counterclockwise, and when pedal turns to C3 by C2, O moves to A3, two springs pair to pedal arm upper pin by A2 around the shaft The direction of pedal arm bearing pin active force is 2 points of B, A2 line of centres direction, and A2 points move around O points, and now big spring is still middle Base is spacing, and little spring spring force is still greater than the spring force of big spring, and big spring do not worked, and center base is not sent out with respect to big spring Raw displacement, in the triangles of 3 points of compositions of O, A3, B, 2 points of A1 and B distance suitably increase, i.e., pedal arm upper pin and step on The distance of board mount upper pin suitably increases, and little spring suitably extends, and spring force diminishes, and two springs produce to pedal arm bearing pin Anticlockwise moment, now two springs are to pedal generation power-assisted effect.4）When pedal travel is reduced to C3 positions, small spring force Identical with high spring force, big spring is equal with little spring spring force to reach balance.When pedal rotates counterclockwise, C4 is turned to by C3 When, O moves to A4 to pedal arm upper pin by A3 around the shaft, and now little spring reaches equal with big spring spring force, center base It is moved, big spring works simultaneously with little spring, and spring integral stiffness diminishes, and causes spring force to diminish, and large and small spring is from pressure Contracting state gradually recovers elastic deformation, and the potential energy discharged is converted into helping the kinetic energy that is rotated around pedal shaft axle of pedal arm, and two Individual spring produces anticlockwise moment to pedal arm upper pin, and now two springs produce power-assisted effect to pedal.6）Pedal arm exists The power-assisted of dual spring resistance gauge gradually increases in rotary course, compared to Single spring structure pedal, due to the stiffness variation of dual spring So that spring force will not sharpness decay, therefore pedal power-assisted will not sharpness decay, reduce the pedal force that customer tramples, carry The comfortableness that high client's pedal is trampled.
