Abstract

The utility model relates to a clutch compensator of a mechanical gearbox automatic transmission system, which can automatically compensate wear extent according to the wearing state of clutch discs automatically. A compensator is arranged on an oil cylinder of a clutch, after the clutch returns to an initial position, a clutch lever pushes an ejector rod of the compensator to return to the initial position. The worn distance of the clutch is the same as the moved distance of the lever when returns to the initial position to cause a sensor to be relatively moved so as to play a role in automatic compensation of the wear extent.

Description

The clutch compensator

Affiliated technical field

The utility model is a kind of clutch compensator of mechanical gear box automatic speed-changing system, can be automatically according to the state of wear of clutch plate, and automatic compensate for wear amount.

Background technique:

At present, the clutch of mechanical gear box automatic speed-changing system generally still adopts the dry type friction clutch, and this clutch in use can fair wear and tear, will cause half hitch to close the skew of Signal Matching point after the wearing and tearing.On the other hand, may wear to certain state, with cisco unity malfunction, exceed allowed band, will threaten the safety of driving as wearing and tearing as untimely adjustment.

Summary of the invention:

Bring the skew of half hitch chalaza in order to overcome the wearing and tearing of dry type friction clutch, can't compensate and exceed the alarm-free deficiency of allowed band automatically, the utility model provides a kind of clutch compensator, whether the wearing and tearing that this compensator can not only be measured clutch exceed allowed band, what and can compensate half hitch automatically and close the position according to wear extent.

The utility model solves the used technological scheme of its technical problem: compensator is contained on the clutch oil cylinder, after clutch is got back to initial position, clutch lever promotes the compensator push rod, get back to initial position, clutch abrasion is how many distances, lever is got back to the also removable same distance of initial position, will promote push rod mobile phase same distance.The front and back push rod is contained in the compensator body, and sensor frame couples together the front and back push rod, and sensor is contained on the sensor frame.Load onto nut on the sensor and sensor frame is fastening, but up-down adjustment, to guarantee the gap of transducing signal.Load onto eccentric shaft on the body, adorn torsion spring on the eccentric shaft, make eccentric shaft push down the tapering of back push rod all the time, then load onto stage clip on the push rod, add a pretightening force opposite with the clutch abrasion direction to push rod.When push rod was promoted left by clutch lever, clutch was opened, and after the thrust cancellation, because spring thrust and eccentric shaft are pressed in the conical surface place of back push rod all the time, thereby push rod can't move to right and returns original position.Because sensor is contained on the sensor frame, together moves with the front and back push rod.Thereby the signal of the sensor same distance that also moves to right, play the effect of automatic compensate for wear amount.Adorn a displacement transducer on the compensator body, when displacement amount reached wearing and tearing permitted value range limit, super scope alarm signal was sent in displacement transducer work.Nut cap by the body right-hand member is adjusted initial tension of spring, and top cover plays encapsulation effect.Load onto seal ring in the eccentric shaft end cap, play supporting, sealing, dustproof effect.When needs reset, utilize the square on the eccentric shaft, eccentric shaft is clockwise rotated, push rod can reset under the effect of spring.

The beneficial effects of the utility model are in the process of dry type friction clutch wearing and tearing, can compensate automatically, guarantee the clutch energy normal reliable work of automatic speed-changing system, when the wearing and tearing ultralimit, report to the police automatically, and compact structure, good manufacturability is suitable for producing in batches.

Description of drawings:

Fig. 1 is that A of the present utility model is to view.

Fig. 2 is a plan view of the present utility model.

Fig. 3 is a B-B of the present utility model portion view.

Among the figure 1, preceding push rod, 2, body, 3, sensor frame, 4, the back push rod, 5, end cap nut, 6, preloading spring, 7, torsion spring, 8, eccentric shaft, 9, seal ring, 10, the clutch oil cylinder, 11, the clutch compensation sensor, 12, eccentric shaft end cap, 13, top cover, 14, seal ring, 15, clutch lever, 16, clutch oil cylinder piston bar, 17, displacement transducer, 18, sensor signal source, 19, the displacement signal source, 20, nut.

In Fig. 1, compensator is contained on the clutch oil cylinder 10, after clutch is got back to initial position, push rod 1 was got back to initial position before clutch lever 15 promoted compensation, clutch abrasion what, clutch lever 15 is got back to after the initial position also mobile phase same distance, push rod 1 mobile phase same distance before promoting.Preceding push rod 1 is contained in the body 2, and sensor frame 3 is preceding push rod 1 and back push rod 4, and clutch compensation sensor 11 is contained on the sensor frame 3, but nut 20 up-down adjustment, to guarantee the gap of transducing signal.Load onto eccentric shaft 8 on the body 2, load onto torsion spring 7 on the eccentric shaft 8, make eccentric shaft 8 push down the tapering of back push rod 4 all the time, unlikely returning then loaded onto preloading spring 6 on the push rod 4, gives the back push rod 4 one pretightening forces.Behind clutch abrasion, when being pushed to the right side, when clutch is opened once more by clutch lever 15, after the thrust cancellation, because the thrust of preloading spring 6 and eccentric shaft 8 under the effect of torsion spring 7, are pressed in the tapering of back push rod 4 all the time, thereby back push rod 4 can't move to left and returns start bit.Because clutch compensation sensor 11 is contained on the sensor frame 3, together move with preceding push rod 1 back push rod 4, thereby the signal of clutch compensation sensor 11 same distance that also moves to right, play the effect of automatic compensate for wear amount.Load onto position transducer 17 on compensator body 2, when displacement amount reached friction damage amount tolerance limit value, super scope warning sign was sent in displacement transducer 17 work.Pretightening force by end cap nut 5 preloading springs 6 of body 2 right-hand members.13 encapsulation effect of top cover are loaded onto seal ring 14 in the eccentric shaft end cap 12, play supporting, sealing, dustproof effect.When needs reset, utilize 4 squares of eccentric shaft 8 tops processing, eccentric shaft 8 clockwise directions are rotated, preceding push rod 1 and back push rod 4 can reset under the effect of preloading spring 6.On the clutch oil cylinder piston bar 16 sensor signal source 18 is housed, displacement signal source 19 is housed on the sensing support 3.
