Abstract

The utility model relates to an adjusting-proof clutch, belonging to the technical field of automobile parts, which is characterized in that a concave convex tooth profile adjusting ring A, a concave convex tooth profile adjusting ring B engaged with the concave convex tooth profile adjusting ring A, between A and B hung a tensile spring, a film spring and a supporting ring fixed in the cover, the outer edge of the film spring pressed on the outer edge of the adjusting ring B, one end of a limit locking plate fixed on an adjusting polar, the other end of a limit locking plate clipped in the opening of the outer edge of the adjusting ring B, one end of the adjusting polar fixed on the cover and the other end of the adjusting polar inserted in the pressure plate groove through the spring A, with the following beneficial effects: with stable pressing force and separating force, no need of adjusting the clearance of the separable bearings of the separation system which needs only enough and stable space to prevent from the faults caused by adjusting improper and/or not in time.

Description

Exempt to adjust clutch

Technical field

The invention belongs to technical field of automobile components.

Background technique

Automobile clutch plays torsion pass, separates multiple functions such as transmission, vibration damping and overload protection in power train, the concern performance of whole automobile of the quality of its quality, but existing its deficiency of friction clutcch of using is: 1) for clutch after the friction disc wear attenuation, the helical spring decrement of coil clutch diminishes, impacting force diminishes gradually, phenomenons such as shaking, skid can appear in clutch, when skidding overlong time, the Friction Disk Surface temperature raises very fast, friction plate is ablated, thereby clutch can not use; Clutch can not in time cut off the transmission of power of motor car engine and power train, causes the gearshift difficulty; The lift of platen is not enough, the clutch transmits friction torque is produced inadequately impact and noise, and riding comfort reduces.The artificial gap of adjusting release bearing in the piece-rate system of our needs when this situation occurring, the wearing and tearing that come the friction compensation sheet are to keep the Separating force of clutch, impacting force and installment state maintenance basically identical.2) for diaphragm spring clutch, when wear extent has been crossed the later friction disc wear of impacting force curve peak, equally the problems referred to above can appear.

Summary of the invention

The purpose of this utility model is:

Provide a kind of self can the compensate for wear amount exempt to adjust clutch.

The technical solution of the utility model is:

On platen, be fixed with concavo-convex profile of tooth adjustment ring A, concavo-convex profile of tooth adjustment ring B and the corresponding interlock of adjustment ring A, adjust ring B and adjust between the ring A and hang with extension spring, diaphragm spring and support ring riveted fixing are in lid, the diaphragm spring outer is pressed in to be adjusted on the ring B outward edge, and spacing jam plate one end is fixed on to be adjusted on the post, and another termination of spacing jam plate is stuck in to be adjusted in the ring B outward edge gap, adjustment post one end is fixed on and covers, and adjusts the post the other end and is plugged in the platen groove by spring A.

The beneficial effects of the utility model are:

Because impacting force and Separating force are stable, need not to adjust the release bearing gap of piece-rate system, piece-rate system only needs enough and stable space, adjusts untimely and adjusts improper and fault that cause with regard to having avoided like this.

Wherein: the 1st, lid, the 2nd, a bucking a rivet, the 3rd, support ring, the 4th, diaphragm spring, the 5th, limiting board, the 6th is adjusted post, the 7th, spacing jam plate, the 8th, jump ring, the 9th, spring A, the 10th, spring B, the 11st, straight pin, the 12nd, platen, the 13rd is adjusted ring A, the 14th, adjusts ring B, the 15th, extension spring, the 16th, driver blade.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further:

Its basic principle is to keep the diaphragm spring mounting point to stablize when friction disc wear to remain unworn installment state, compensation mechanism works continuously according to the friction plate thickness of wearing and tearing gradually, this automatic compensation structure is mainly by two compensated loops (as shown in Figure 1) and three extension springs, a spacing jam plate, a limit is lived compositions such as post, and structure as shown in Figure 3.

Diaphragm spring and lid, support ring rely on rivet together, adjust and encircle in the opening slot that under the effect of spacing tapered end plate adjustment post, is pressed on the platen, the rivet at driver blade two is riveted on respectively on lid and the platen, make each component on lid, diaphragm spring, platen and the platen be connected to an axially movable only integral body, between limiting stopper and the adjustment post is welding, between spacing jam plate and the adjustment post is welding, and adjusting between the ring is to match by convex-concave to be connected with extension spring.

Behind the friction disc wear, outer ring, diaphragm spring dish district (work circle) pressing adjustment ring and platen to shift to flywheel together, and at this moment clutch cover drives and adjusts post and the flywheel displacement dorsad of spacing jam plate, and adjusting to encircle between B and the spacing jam plate just has certain interval L, shown in Figure 5.

When the system operation clutch separation, lift outer ring, diaphragm spring dish district (work circle), adjust ring A and adjust the impacting force that ring B has not had diaphragm spring, frictional force disappears substantially, and two adjust ring relatively rotates by the power of draw ring, until paste and, two adjust ring highly increases, the gap of adjusting between ring B and the spacing jam plate disappears, and diaphragm spring is got back to initial installment state again, has finished automatic adjustment work.

Claims

1, a kind ofly exempts to adjust clutch, mainly comprise lid, platen, it is characterized in that: on platen, be fixed with concavo-convex profile of tooth adjustment ring A, concavo-convex profile of tooth adjustment ring B and the corresponding interlock of adjustment ring A, adjust ring B and adjust between the ring A and hang with extension spring, diaphragm spring and support ring riveted fixing are in lid, the diaphragm spring outer is pressed in to be adjusted on the ring B outward edge, spacing jam plate one end is fixed on to be adjusted on the post, another termination of spacing jam plate is stuck in to be adjusted in the ring B outward edge gap, adjustment post one end is fixed on and covers, and adjusts the post the other end and is plugged in the platen groove by spring A.
