Thebase plate 1 is provided with asealing plate 18, after thepedal 2 is stepped on, the connecting part of thepedal 2, the first connectingrod 6, the second connectingrod 7 and thegas column spring 5 are all embedded in a groove formed by thesealing plate 18, thesealing plate 18 is of a groove-shaped structure, and the sealing plate and thebase plate 1 are of an integral structure formed in one step, so that the sealing of front and rear spaces is realized.

During installation, thebase plate 1 is installed on a reserved position of a vehicle body, the fixingplate 12 is connected with the transmission rod to realize connection with the clutch in the vehicle, and the connection structure is the same as the connection mode of the existing pedal and the clutch. Thepedal 2 is then stepped on a number of times to sense the clutch elevation and thereby determine whether theadjuster bolt 17 needs to be installed in thebolt hole 3 and the position of the adjuster bolt adjusted.

The operation of thepedal 2 is divided into two steps, a step-on step and a reset step, and each step comprises three states, namely an initial state, a critical state and a final state.

In the step of stepping on the pedal, the pedal is rotated in a positive direction,

in an initial state, the first connectingrod 6 abuts against the shiftingpiece 8, thetorsion spring 9 is in a compressed state, the piston rod of thegas column spring 5 extends out, and the blockingpiece 14 abuts against the adjustingbolt 17 or the first limitingpiece 15;

when the clutch moves from the initial state to the critical state by overcoming the resistance of the clutch, thetorsion spring 9 provides assistance and gradually resets, theair column spring 5 provides resistance and gradually compresses, and the resistance of the clutch is continuously increased. Because the torsion spring is compressed and deformed maximally and has the greatest elasticity at this stage, theair column spring 5 and the clutch spring just start to be compressed, the included angle between the first connectingrod 6 and the second connectingrod 7 is continuously increased, the moment is reduced, the resistance of theair column spring 5 is limited by the moment and is not large, and the power of the assisting force and the pedaling is larger than the resistance.

When the critical state is reached, theair column spring 5 is compressed to the maximum deformation, and the first connectingrod 6 and the second connectingrod 7 are collinear.

When the critical state moves to the final state, thegas column spring 5 resets to provide assistance, the first connectingrod 6 is separated from the shiftingpiece 8, the resistance of the clutch spring continues to increase, and due to the change of the included angle between the first connectingrod 6 and the second connectingrod 7, although the deformation of thegas column spring 5 is gradually reduced, the assistance can still be stably provided.

When thepedal 2 is released, a resetting step is carried out, the pedal drives theshaft sleeve 5 to rotate in the reverse direction, the whole body passes through the steps of a final state, a critical state and an initial state, the power assistance in the step of stepping is shifted to resist and the resistance is shifted to assist, but the pedal is reset under the pushing of the clutch spring due to the fact that the driving force of stepping is lost.

Example 1

Parameter changes in the lower column process:

without the booster, the delivery of the rotation of the connecting part of thepedal 2 along thebushing 4 is ≤ α as a variable, and the pedal force F required for the stationary state of the pedal is maintained at ≤ α, which is positive if the force contributes to the pedal depression and negative if the force hinders the pedal depression. The angle is in degrees and the force is in N.

∠α	F4

24	220
		48	420

Example 2

Parameter changes in the lower column process:

the device is connected with a clutch of an automobile, the delivery of the rotation of the connecting part of thepedal 2 along theshaft sleeve 4 is & lt alpha as a variable, the treading force F required when the pedal is kept still under the & lt alpha is kept, if the force is helpful to treading the pedal, the numerical value is positive, and if the force is in order to hinder the treading of the pedal, the numerical value is negative. The angle is in degrees and the force is in N.
