Abstract
A clearance self-regulation and wear compensation mechanism for a disc brake comprises a brake caliper body, a piston, a rectangle ring, a dustproof ring, a brake support, a friction plate and a brake and is characterized in that a friction resistance sleeve and a friction resistance ring are additionally arranged behind the piston. The clearance self-regulation and wear compensation mechanism for the disc brake has the advantages that the early-stage damage of the friction plate caused by pull friction can be effectively avoided; the mechanism has the automatic compensation function for the wear of the friction plate and does not need to be regulated by a user, thereby reducing the use difficulty and the maintenance difficulty; and the structure is simpler, the assembly difficulty and the maintenance difficulty are low, and the reliability is high.
Description
Technical field the utility model relates to field of mechanical technique, particularly disk brake clearance self-regulating and wear compensation mechanism.
The application of background technique disc brake with floating caliper on automobile is very ripe, and its concrete working principle is as shown in Figure 1, through the distortion return of the interior rectangular loop of braking clamp body (1) (3); Form brake clearance; When the driver steps on brake petal, produce hydraulic coupling, promote piston (2) reach; Rectangular loop (3) is driven by piston (2) and produces distortion, and piston (2) withstands on brake disc (7) with friction plate (6) and goes up the realization braking; When the driver loosened the brake, hydraulic coupling disappeared, and under the effect of rectangular loop (3) deformation force, piston (2) is retreated, and realized that braking separates.
For meeting the market requirement; Need disc brake with floating caliper be applied on the self-propelled combine; Because keep the existing chassis of combine-harvester drive mechanism, and that the position between brake calipers and brake disc can't be accomplished with the automobile that kind is accurate, so there is the serious problem of dawdling.
The purpose of summary of the invention the utility model provides a kind of disk brake clearance self-regulating and wear compensation mechanism; This clearance self-regulating and wear compensation mechanism are a solution that proposes to the problem that exists in the background technique; Have relatively simple for structure; Assembling and maintenance difficulty are low, the advantage that reliability is high.
The purpose of the utility model realizes through following technological scheme: a kind of disk brake clearance self-regulating and wear compensation mechanism; Comprise braking clamp body, piston, rectangular loop, dust ring, brake holder, friction plate and brake disc, it is characterized in that having increased surface friction drag cover and surface friction drag ring at the back at piston.
Reinstall a pull bar and return spring in the surface friction drag cover described in the technique scheme.
The early stage damage that this disk brake clearance self-regulating and wear compensation mechanism effectively avoid friction plate to cause because of dawdling; Band friction disc wear automatic compensation function, and do not need artificial adjustment, reduced the use maintenance difficulty; Relatively simple for structure, assembling and maintenance difficulty are low, and reliability is high.
Description of drawings Fig. 1 is the structural representation of original disk type braker.
Fig. 2 is the structural representation of the utility model.
Among the figure, braking clamp body (1), piston (2), rectangular loop (3), dust ring (4), brake holder (5), friction plate (6), brake disc (7), surface friction drag ring (8), surface friction drag cover (9), seal ring (10) and return spring (11).
Embodiment is described further the utility model below in conjunction with accompanying drawing and embodiment.
Fig. 2 is the structural representation of the utility model, has increased by one group of surface friction drag ring (8) and surface friction drag cover (9) in piston (2) back, and surface friction drag ring (8) closely contacts with braking clamp body (1) internal surface, produces surface friction drag.Reinstall a pull bar and return spring (11) in the surface friction drag cover (9) and realize the braking return, the return pull bar is fixed on piston (2) through screw thread and goes up compression retracteding position spring (11) simultaneously, with the preset brake clearance of surface friction drag cover (9) design.
Forces associated parameter in the present embodiment:
After F1 surface friction drag ring is press-fited the cylinder hole of caliper into, the axial friction of generation.
During F2 spring working state, to the pulling force of piston.
During F3 spring pre-compression force state, to the pulling force of piston.
The axial rub resistance that F4 seal ring assembling back produces.
The size of each power: F1＞F2＞F3＞F4
After the assembling, return spring (11) is by after the precompression, and piston (2) is produced tensile force f 3, because of F3 much smaller than F1, piston (2) is close to surface friction drag cover (9), is in the bottom in the cylinder hole of braking clamp body (1).
After the driver stepped on brake petal, brake fluid promoted piston (2) reach through the oil-through hole on the surface friction drag cover (9); After eliminating preset brake clearance, friction plate (6) is adjacent to brake disc (7), produces braking; Return spring this moment (11) is produced spring force F2 by further compression, but because of F2＜F1; Surface friction drag cover this moment (9) keeps motionless under power F1 effect in the home position.
When friction plate (6) wearing and tearing; When causing brake clearance greater than prepsetting gap, hydraulic oil can promote piston (2) earlier and overcome reach, after prepsetting gap is eliminated; Hydraulic coupling can further increase; And overcome making a concerted effort of F1, F2, F3, and drive piston (2) and move a segment distance forward with surface friction drag cover (9), eliminate the wearing clearance that weares and teares and cause.
After the driver loosens the brake; Hydraulic coupling disappears; Piston (2) is adjacent to surface friction drag cover (9) under power F2 effect again, and the resistance F1 on the surface friction drag cover (9) will be much larger than F2; So surface friction drag cover (9) keeps motionless at reposition, continue to keep preset brake clearance between return pull bar and surface friction drag cover (9).
Through the service testing on reaper; Braking moment satisfies the car load requirement, 20 kilometers/hour of F-Zeros, 5.5 meters of average stopping distances; Stopping distance is 5.85 meters farthest, satisfies the longest 6 meters requirement in the requirement of JB/T5117-2006 full-feeding combine harvester technical specifications fully; Clearance automatic compensation is good, and the problem of dawdling is resolved, and residue is held in the palm the moment 8N.m that stagnates, and has reached the standard-required of automobile industry, satisfies the reaper needs fully; Friction disc wear is mended automatically, has effectively reduced maintenance cost.
