Description
Technical field
The utility model relates to a kind of automobile clutch pedal with torsion spring assist function, belongs to the auto pedal technical field of structures.
Background technology
At present, known automobile clutch pedal structure is made up of elements such as clutch pedal support, clutch pedal arm, swivel pin, nyliners.The principle of work of pedal is a lever principle.Clutch pedal support, nyliner, swivel pin, pedal arm are assembled together, pedal arm is rotated relative to pedal support around swivel pin.By adjusting the position of the relative pedal arm of swivel pin, select suitable lever ratio, realize increasing pedal stroke, reduce the effect of the pedal force of pedal.
In this conventional confguration, when pedal effort can increase along with the increase of engine torque.If want to reduce treadle effort, must select big lever ratio for use, will certainly cause the increase of pedal stroke like this.When the distance that the stroke of pedal is stipulated above human engineering, can cause handling difficulty, traveling comfort descends.Traditional pedal can not make the pedal control difficulty, fatiguability keeping transmitting ratio unmodified situation to reduce treadle effort.
Summary of the invention
Can not be in order to overcome existing pedal in the defective that keeps reducing under the pedal stroke unmodified situation treadle effort, a kind of automobile clutch pedal of the utility model design with torsion spring assist function, this pedal can be on the basis of treadle effort that has designed and travel relationships, has mechanically aided function, reduce treadle effort once more, can not cause the increase of pedal stroke simultaneously.
The technical solution of the utility model is: the automatic clutch with torsion spring assist function of the present utility model is stepped on and is comprised pedal support, by swivel pin and pedal support pivotally attached pedal arm, pull back spring, between the middle part of pedal arm and pedal support, torsion spring is installed, torsion spring is symmetrically arranged in the both sides of pedal arm, it is spacing by pedal arm that arm is turned round in the centre of torsion spring, and two are stretched out about torsion spring, and to turn round arm spacing by pedal support.
Described torsion spring is symmetrically arranged by two single torsion springs, and two adjacent arms of turning round of single torsion spring link together, and arm is turned round in the centre that constitutes torsion spring, and two were stretched out about two single torsion spring outsides were turned round arm and are turns round arm.
The centre of described torsion spring is turned round and is established the first lubricated nyliner of antifriction between arm and the pedal arm.
The second lubricated nyliner of antifriction is established in turning round that two are stretched out about described torsion spring between arm and the pedal support.
Described torsion spring is hinged with being connected of pedal arm and pedal support.Turn round arm at pedal arm apart from the centre of the position assembling torsion spring of S. A. 75-80mm.
The beneficial effects of the utility model are: can be when not changing the clutch pedal transmitting ratio, and effectively the pedal force of chaufeur only adopts a double torsion spring in the force aid system of pedal, and is simple in structure.
Description of drawings
Fig. 1 is an overall structure scheme drawing of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is that torsion spring is installed enlarged drawing.
The specific embodiment
Fig. 1, Fig. 2 are structural representations of the present utility model: the automatic clutch with torsion spring assist function of the present utility model is stepped on and is comprised pedal support 1, by swivel pin 2 and pedal support 1 pivotally attached pedal arm 3, pull back spring 4, torsion spring 5 is installed between the middle part of pedal arm 3 and pedal support 1, torsion spring 5 is symmetrically arranged in the both sides of pedal arm 3, it is spacing by pedal arm 3 that arm is turned round in the centre of torsion spring 5, and two are stretched out about torsion spring 5, and to turn round arm spacing by pedal support 1.
Described torsion spring 5 is symmetrically arranged by two single torsion springs, and two adjacent arms of turning round of single torsion spring link together, and arm 5a is turned round in the centre that constitutes torsion spring 5, and two were stretched out about two single torsion spring outsides were turned round arm and are turns round arm 5b.
Turn round arm 5a at pedal arm 3 apart from the centre of the position of S. A. 75-80mm assembling torsion spring 5, the centre is turned round arm 5a and is installed in first nyliner 6 on pedal arm 3.It is lubricated that nyliner plays antifriction.
Fig. 3 is that torsion spring installation enlarged drawing: 3a is the installation sheet of torsion spring 5 on pedal arm 3.
When pedal arm 3 clockwise rotated, the centre of torsion spring 5 was turned round the B point of arm 5a on pedal support 1 and is rotated, and turned round arm 5b when the C point rotates for two about the other end, rotated around swivel pin 2 with pedal arm.Torsion spring 5 is in compressive state, produces a twisting force on pedal arm 3, and the size of torsion reduces with the increase of the distance that B point, C are ordered, and the direction of torsion is pointed to C by B on the line of 2 of BC.Turn round in the process of arm 5b with the motion of C point for two about torsion spring 5, when the C point moved to 2 lines of D, B, the torsion of 5 pairs of pedal arms 3 of torsion spring was by the axis of swivel pin 2, and the arm of force is 0, and this moment, the power-assisted effect was 0.When the rotation of C point with pedal arm 3, when moving to D, B line, the relative swivel pin 2 of torsion produces an anticlockwise moment, in this section stroke, 3 resistance effects of 5 pairs of pedal arms of torsion spring, along with the C point more and more near D, B line, anticlockwise moment reduces gradually, and resistance is more and more littler, until to 0.When the C point is crossed D, the B line continues to move downward, the torsion of 5 pairs of pedal arms 3 of torsion spring produces a clockwise moment, along with the C point away from D, B line, moment increases gradually, until to greatest limit, begins subsequently to reduce, until 0.In this section stroke, 3 power-assisted effects of 5 pairs of pedal arms of torsion spring when clockwise moment is maximum, also are that the power-assisted effect is best the time.Can see from path of motion with upper pedal arm, cw motion along with pedal arm 3, the moment of 5 pairs of pedal arms 3 of torsion spring is to be reduced to 0 gradually, oppositely be increased to maximum, be reduced to 0 process once more, and in the both sides of D, B line, the moment effect that torsion spring 5 produces is symmetrically distributed.Generally, design when can obtain lower treadle effort like this, can also obtain the effect of the rapid return of pedal arm at the end position of pedal stroke when the assist torque cw was reduced to 0.
In clutch pedal, pedal arm is connected by swivel pin with pedal support, assembles a double torsion spring, makes double torsion spring one end and pedal arm hinged, and the other end and pedal support are hinged.When chaufeur is trampled clutch pedal arm one end,, pedal force and the stroke other end from pedal arm is spread out of by the rotation of pedal arm around swivel pin.When pedal arm when swivel pin rotatablely moves, torsion spring compressive state again recovers elastic deformation gradually, the elastic potential energy that discharges changes into the kinetic energy that helps the rich swivel pin of pedal arm to rotate, and reduces the pedal force of chaufeur.Thereby realized not changing under the prerequisite of pedal stroke and transmitting ratio, reduced the purpose of pedal force.
