Abstract

The utility model discloses an automobile clutch pedal mechanism, which has long service life and reliable performances and comprises a pedal, a pedal handle, a hinged shaft and an oil pump piston rod. The hinged shaft is a stepped shaft, and a bearing is installed on a thick shaft of the hinged shaft in sleeved mode. The upper portion of the pedal handle is integrally welded with an outer ring of the bearing. The upper end of the oil pump piston rod is installed on a thin shaft of the hinged shaft and matched with the thin shaft in rotating mode, and nuts are screwed at both ends of the hinged shaft. In the automobile clutch pedal mechanism, the hinged shaft is a stepped shaft, the bearing and the oil pump piston rod are respectively installed on different shaft sections of the hinged shaft and no friction occurs to each other. The upper portion of the pedal handle is integrally welded with the outer ring of the bearing, enabling the pedal handle to have an indirect matching relationship with the hinged shaft through the bearing instead of having a direct relationship with the hinged shaft. Therefore, no friction occurs between the hinged shaft and the pedal handle. Due to the adoption of the bearing, not only friction is reduced but also resistance caused by stepping the pedal is reduced, service life is greatly increased, and performance of the clutch pedal mechanism is more reliable.

Description

Car clutch pedal mechanism

Technical field

The utility model relates to a kind of car clutch pedal mechanism.

Background technology

Existing car clutch pedal mechanism mainly is made up of pedal, treadle lever, hinge and oil pump piston bar, and treadle lever top is provided with axis hole, and hinge penetrates in this axis hole.During work, following pedal also drives treadle lever and moves down, and makes the oil pump piston bar promote oil pump work.Because said structure rubs axis hole and hinge on the treadle lever, after the time was long, axis hole ground increasingly, has influenced the stroke of power-transfer clutch, often causes clutch not thorough, and engage a gear is had some setbacks, and had just also usually occurred the phenomenon of stopping working during engage a gear.Long-term use causes damage to parts such as clutch segment, platen, change speed gear boxs, easily causes traffic accident when serious.

Summary of the invention

The purpose of this utility model provides the car clutch pedal mechanism of a kind of long service life and dependable performance.

The technical solution of the utility model is: comprise pedal, treadle lever, hinge and oil pump piston bar, described hinge is a stepped shaft, be set with bearing on the thick axle of hinge, treadle lever top and outside race are welded as a whole, oil pump piston bar upper end is contained on the thin axle of hinge, and cooperate with thin axle rotation, the hinge two ends are rotary with nut.

Technique effect of the present utility model is: hinge is a stepped shaft, and bearing is divided on the different shaft parts of hinge with the oil pump piston bar, does not rub each other; Treadle lever top and outside race are welded as a whole, make treadle lever not with hinge generation direct relation, but by bearing and hinge indirect matching relationship takes place, therefore, hinge and treadle lever can not rub.Because the effect of bearing, not only reduced the resistance that friction force has also reduced time pedal, improve service life greatly, and the performance of clutch pedal mechanism is more reliable.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail, but does not constitute any restriction of the present utility model.Illustrated in figures 1 and 2, the utility model comprises pedal, treadle lever 4, hinge 1 and oil pump piston bar 5, described hinge 1 is a stepped shaft, be set with bearing 2 on the thick axle of hinge 1, treadle lever 4 tops and outside race are welded as a whole, oil pump piston bar 5 upper ends are contained on the thin axle of hinge 1, and hinge 1 two ends are rotary with nut 6.Generally speaking, outside race is difficult to welding, is head it off, can add snare 3 of cover on outside race, and snare 3 and outside race interference fit are welded as a whole treadle lever 4 tops and snare 3 then.For the sake of assurance, can axis hole be set, it is sleeved on the hinge 1, be one with snare 3 welderings then on treadle lever 4 tops.Even after the solder joint sealing-off, treadle lever 4 still is enclosed within on the hinge 1 like this, clutch pedal mechanism still can normal operation, the reliability and the safety of clutch operating when having improved driving.Operating process is as follows: the pin push down on the pedal, pedal drives treadle lever 4 and moves down, treadle lever 4 drives the outside race rotation makes hinge 1 move down simultaneously, and the oil pump piston bar 5 that is contained on the hinge 1 moves down synchronously, and the lower end of oil pump piston bar 5 acts on and opens relevant work on the oil pump.When returning when lifting pedal, whole process is opposite with said process, does not repeat them here.Trample and return in the process of lifting at pedal, also have the cooperation of some peripheral auxiliaries, as spring etc., because of these structures all belong to prior art, industry those of ordinary skill is all known, and is not described in detail in this.
