Abstract
The invention discloses an adjusting device based on an automotive brake adjusting arm. The adjusting device comprises an adjusting arm body, a plug pin arranged at the front end of the adjusting arm, a circular ring arranged at the lower part of the plug pin and used for fixing, a cylindrical pin arranged in the middle of the adjusting arm and a spring connected with the circular ring and the cylindrical pin and arranged between the circular ring and the cylindrical pin; a plurality of equally-spaced arc grooves are formed in a plug pin gasket; the cylindrical pin is mutually clamped with the arc grooves through the spring. The implementation of the adjusting device based on the automotive brake adjusting arm has the beneficial effects that the elasticity stability of the adjusting arm is improved, the adjusting arm is simple in structure and convenient to assemble, the plug pin processing steps are reduced, and the production cost of the whole adjusting arm is reduced.
Description
Technical field
The present invention relates to the field of braking adjusting-arm, more particularly, relate to a kind of regulating device based on braking automobile adjustment arm.
Background technique
The braking of vehicle generally all utilizes the contact friction function between brake shoe and brake drum to realize.In the process of driving, meeting contact friction continually between brake shoe and brake drum, make gap between the two become large, this can affect the Security of vehicle brake mechanism work.So all adjustment arm can be provided with in the arrestment mechanism of vehicle, in order to adjust the brake clearance between brake shoe and brake drum, make brake clearance between the two can keep a steady state value, to ensure the Security of vehicle brake mechanism work.Current braking automobile adjustment arm is the important component part in motor vehicle braking system, and the braking adjusting-arm of prior art is assemblied by parts such as housing, worm screw, worm gear and linings usually.
The regulating mechanism of current adjustment arm comprises latch, nut, plum-blossom sleeve, locking screw, locking hoodle, extruding hoodle and extrusion spring, because the front-end face extruding hoodle of locking screw exists certain gap, and extrude stressed larger, spring force is caused to reduce, reduce the working life of extrusion spring, accessory is more, assembles more complicated, and latch manufacturing procedure is many, add the cost of production of whole adjustment arm simultaneously.
Summary of the invention
Technical problem to be solved by this invention is, a kind of regulating device based on braking automobile adjustment arm is provided, the prior art problem that working life in order to solve prior art is low, accessory is more, manufacturing procedure is complicated and cost of production is higher, realize that regulating mechanism structure is simple, easy to assembly, latch manufacturing procedure reduces, saved the cost of production of whole adjustment arm.
The present invention solves the problems of the technologies described above, there is provided the following technological scheme solved: a kind of regulating device based on braking automobile adjustment arm, it comprises adjustment arm body, be arranged at the latch of adjustment arm front end, to be arranged at below latch for fixing annulus, to be arranged at the straight pin in the middle part of adjustment arm and to connect annulus and straight pin and the spring be arranged between annulus and straight pin;
Described stub key washer is provided with multiple equally spaced arc groove, described straight pin is clamped mutually by spring and arc groove.
In the regulating device based on braking automobile adjustment arm of the present invention, the groove direction of described arc groove extends along adjustment arm direction.
In the regulating device based on braking automobile adjustment arm of the present invention, described latch is provided with hexagon nut.
In the regulating device based on braking automobile adjustment arm of the present invention, described straight pin is provided with stub key washer, for the stressed degree of damping spring.
Implement the regulating device based on braking automobile adjustment arm of the present invention, have following beneficial effect: the elastic stability that improve adjustment arm, structure is simple, easy to assembly, and its latch manufacturing procedure reduces, and has saved the cost of production of whole adjustment arm.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the structural representation of the regulating device based on braking automobile adjustment arm of the present invention;
1, latch, 2, annulus, 3, spring, 4, straight pin, 5, stub key washer, 6, adjustment arm body.
Embodiment
In order to make object of the present invention, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, be the structural representation of the regulating device based on braking automobile adjustment arm of the present invention; Based on a regulating device for braking automobile adjustment arm, it comprises adjustment arm body, be arranged at the latch of adjustment arm front end, to be arranged at below latch for fixing annulus, be arranged at the straight pin in the middle part of adjustment arm and connect annulus and straight pin and the spring be arranged between annulus and straight pin;
Described stub key washer is provided with multiple equally spaced arc groove, described straight pin is clamped mutually by spring and arc groove.
In the regulating device based on braking automobile adjustment arm of the present invention, the groove direction of described arc groove extends along adjustment arm direction.
In the regulating device based on braking automobile adjustment arm of the present invention, described latch is provided with hexagon nut.
In the regulating device based on braking automobile adjustment arm of the present invention, described straight pin is provided with stub key washer, for the stressed degree of damping spring.
Compared with prior art, implement the regulating device based on braking automobile adjustment arm of the present invention, there is following beneficial effect: the elastic stability that improve adjustment arm, structure is simple, easy to assembly, its latch manufacturing procedure reduces, and has saved the cost of production of whole adjustment arm.
The above embodiment only have expressed embodiments of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
