The object of this invention is to provide a kind of automobile clutch release system, it can after the friction disc wear of clutch be thinning, and auto-compensation clutch separation points to the distance of rear movement.
Automobile clutch release system of the present invention, comprise pedal, adjusting nut, drag-line, fork, release bearing, clutch, drag-line screw rod, support, pedal is connected with one end of drag-line, the other end of drag-line is connected with shift fork, described release bearing and fork are connected, and the separation finger on clutch and release bearing are connected; Described drag-line screw sleeve is on drag-line, and adjusting nut is assemblied on drag-line screw rod; Also comprise drag-line crust, adjustment spring, compensate nut and torsion spring; Described adjusting nut is with a joint hollow shaft, and hollow shaft sleeve on drag-line screw rod and drag-line, and passes the via hole on support; Described adjustment spring housing is on the hollow shaft of adjusting nut, and two ends are conflicted respectively in the nut head and support of adjusting nut; The hollow shaft of adjusting nut has outside thread through one end of support, assembling compensation nut it on; In compensation nut, be provided with torsion spring, one end is fixed on and compensates on nut, and the other end is fixed on support, and the end face of compensation nut and support is fitted; Described drag-line crust is between drag-line screw rod and pedal, and drag-line passes from drag-line crust, and the two ends of drag-line crust are fixedly connected with vehicle body and drag-line screw rod respectively.
Further, the hollow shaft on adjusting nut coordinates with standoff gap.
Further, before clutch abrasion, the compressive strain power of described adjustment spring equals maximum separation power before clutch abrasion.
Further, the end of described drag-line is connected with the end of fork by ball pivot.
Automobile clutch release system of the present invention, owing to having said structure, drag-line crust limits the movement locus of drag-line, when drag-line is pulled, drag-line crust is produced to the effect of power, drag-line crust by this reaction force acts on adjusting nut, work as clutch abrasion, clutch maximum separation power will become large, when pushing down on the pedal, the reaction force acting on drag-line crust also will become large, compress adjustment spring under the effect of adjusting nut, adjusting nut and compensation nut move backward relative to support, and by compensating nut by this displacement locking.Owing to moving behind the position of adjusting nut, move behind the position that namely drag-line is connected with fork, thus the distance of moving after separation finger after compensate for clutch abrasion, achieve the auto-compensation to clutch abrasion.

Embodiment
In order to explain technological scheme of the present invention further, below by coming by reference to the accompanying drawings, the present invention will be described in detail.
See described in Fig. 1 to Fig. 3, automobile clutch release system, comprise pedal 14, adjusting nut 2, drag-line 10, fork 7, release bearing 11, clutch 6, drag-line screw rod 9, support 8, drag-line crust 1, adjustment spring 3, compensate nut 4 and torsion spring 5, pedal 14 is connected with one end of drag-line 10, the other end of drag-line 10 is connected by the end of ball pivot with fork 7, described release bearing 11 is connected with fork 7, and the separation finger 13 on clutch is connected with release bearing 11; Described drag-line screw rod 9 is enclosed within drag-line 10, and adjusting nut 2 is assemblied on drag-line screw rod 9; Described adjusting nut 2 is with a joint hollow shaft, and hollow shaft sleeve on drag-line screw rod 9 and drag-line 10, and passes the via hole on support 8, with support 8 Spielpassung.Described adjustment spring 3 is enclosed within the hollow shaft of adjusting nut 2, conflicts respectively in the nut head and support 8 of adjusting nut in two ends.The hollow shaft of adjusting nut 2 has outside thread through one end of support 8, assembling compensation nut 4 it on; In compensation nut 4, be provided with torsion spring 5, one end is fixed on and compensates on nut 4, and the other end is fixed on support 8, and compensation nut 4 is fitted with the end face of support 8; Described drag-line crust 1 is between drag-line screw rod 9 and pedal 14, and drag-line 10 passes from drag-line crust 1, and the two ends of drag-line crust 1 are fixedly connected with vehicle body and drag-line screw rod 9 respectively.Before clutch abrasion, the compressive strain power of described adjustment spring equals maximum separation power before clutch abrasion, and namely before clutch abrasion, whole system is stressed is less than clutch maximum separation power, now adjusts spring indeformable.
Working principle of the present invention is as follows:
Under pedaling force F effect, drag-line produces pulling force, one end due to drag-line crust is fixed on vehicle body, the motion of drag-line is produced and hinders (orbiting motion that namely can only limit along drag-line crust), when pulling drag-line, drag-line crust will be subject to the effect of reaction force, and this power is passed through drag-line screw acting on adjusting nut.During known pedal, adjusting nut is by end thrust to the right, and this thrust just acts on adjustment spring.According to clutch characteristics, when after clutch abrasion, clutch maximum separation power becomes large, and namely pull the pulling force of drag-line also will become large, the known reaction force acting on drag-line crust during drag-line that pulls also becomes large.When after clutch abrasion, under pedaling force F effect, now adjust spring to be compressed, adjusting nut opposite brackets together with compensation nut moves backward, and now compensation nut and support there will be gap, under the twisting force of torsion spring, compensate nut meeting automatic tightening, make the end face compensating nut all the time near the end face of support, avoid after pedaling force F disappears, adjustment recoil of spring.After completing above-mentioned compensation, compared with before compensation, move behind the position of adjusting nut, move behind the position that namely drag-line is connected with fork, thus the distance of moving after separation finger after compensate for clutch abrasion, its effect is as shown in Figure 3.Along with the clutch later stage continues wearing and tearing, pulling force suffered by drag-line heart yearn continues to increase, and adjustment spring also can continue to be compressed, and compensating nut can continued compensation.
