The purpose of this utility model is achieved in that
A kind of car clutch pedal with work-saving device and adjustable stroke, comprise pedal support, bearing, clutch pedal switch, collision block, pedal arm and foot pedal pad, with the middle and upper part bottom of clutch mass cylinder push rod bonded assembly bearing installation at pedal arm, collision block is installed in the bottom, middle and upper part of pedal arm, the next door of bearing, the contact of clutch pedal switch contacts with collision block on being contained in pedal arm to gather the signal of pedal of clutch operation, feature is: be equipped with by power assistant spring at the top of pedal arm, the work-saving device that jump ring and shifting block are formed, in the welded top of pedal arm the pedal arm rotating shaft, in pedal arm rotating shaft the inside plastic bushing and bushing pipe are installed, bearing pin passes the pedal arm rotating shaft, plastic bushing, bushing pipe and pedal support, by the bearing pin nut pedal arm and pedal support are connected together, make pedal arm to rotate around bearing pin; Top left at pedal arm is fixed with the shifting block that band is linked up with, and the two ends of power assistant spring are fixed on the pedal support by spring bushing, and the centre of power assistant spring is stuck in the hook of shifting block by jump ring.
Be fixed with the pedal limiting bracket in band limit mounting hole in the left side, middle part of pedal arm, the nut of caging bolt down, the screw rod of caging bolt is clamped on the pedal limiting bracket by fastening screw nut and captive nut after being upward through the limit mounting hole of pedal limiting bracket.
The utility model is set up power assistant spring by the top at pedal arm, and design the installation site of power assistant spring according to clutch driving disc separating force curve, first section that is implemented in pedal stroke suitably increases treadle effort, back segment at pedal stroke alleviates treadle effort, to improve the traveling comfort that pedal of clutch is handled.The utility model has also been set up a caging bolt at the middle part of pedal arm, realize adjusting to the pedal of clutch total kilometrage by regulating caging bolt.Therefore, the utlity model has by on pedal, install additional work-saving device with the operating effort that alleviates pedal, the traveling comfort, the pedal stroke that improve pedal control can regulate, advantage simple in structure, easy for installation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 be among Fig. 1 A-A to scheme drawing;
Fig. 3 is the right elevation of Fig. 1;
Fig. 4 is the principle instruction diagram of work-saving device.
The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
A kind of car clutch pedal with work-saving device and adjustable stroke, comprise pedal support 1, bearing 2, clutch pedal switch 3, collision block 4, pedal arm 5 and foot pedal pad 10, be installed in the bottom, middle and upper part of pedal arm 5 with clutch mass cylinder push rod bonded assembly bearing 2, collision block 4 is installed in the bottom, middle and upper part of pedal arm 5, the next door of bearing 2, the contact of clutch pedal switch 3 contacts with collision block 4 on being contained in pedal arm 5 to gather the signal of pedal of clutch operation, be equipped with by power assistant spring 14 at the top of pedal arm 5, the work-saving device 17 that jump ring 13 and shifting block 15 are formed, in the welded top of pedal arm 5 pedal arm rotating shaft 18, inwall in pedal arm rotating shaft 18 is equipped with plastic bushing 22 and bushing pipe 23, bearing pin 16 passes pedal arm rotating shaft 18, plastic bushing 22, bushing pipe 23 and pedal support 1, by bearing pin nut 24 pedal arm 5 and pedal support 1 are connected together, make pedal arm 5 to rotate around bearing pin 16; Welded band in the top left of pedal arm 5 and linked up with 11 shifting block 15, the two ends of power assistant spring 14 are fixed on the pedal support 1 by spring bushing 20, and the centre of power assistant spring 14 is stuck in the hook 13 of shifting block 15 by jump ring 15.
Be fixed with the pedal limiting bracket 9 in band limit mounting hole 19 in the left side, middle part of pedal arm 5, the nut of caging bolt 6 down, after the screw rod of caging bolt 6 is upward through the limit mounting hole 18 of pedal limiting bracket 9, be clamped on the pedal limiting bracket 9 by fastening screw nut 8 and captive nut 7.
