Technical Field

The utility model belongs to the technical field of automobile parts, concretely relates to car floating caliper disc brake pincers body.

Background

The main functions of a vehicle brake system are to decelerate or even stop a running vehicle, to stabilize the speed of a vehicle running downhill, and to immobilize a stopped vehicle in place (including on a slope), which may be classified as a drum brake and a disc brake. The automobile brake system directly influences the running safety and the parking reliability of the automobile, and has important significance for the research of the automobile brake system. The automobile floating caliper disc brake caliper body is used as one of key parts of an automobile braking system, and the existing automobile floating caliper disc brake caliper body has the defects of heavy structural mass and the like.

SUMMERY OF THE UTILITY MODEL

In view of this, the present invention provides a light-weight floating caliper disc brake caliper body for an automobile.

In order to achieve the above purpose, the utility model provides the following technical scheme:

the utility model provides a car floating caliper disc brake pincers body, its pincers body pincers back of the body comprises the rotator of lower floor, the reinforcement on upper strata, and the projection of reinforcement on the rotator is type W type.

Furthermore, the thickness of the reinforcing body protruding rotating body is gradually increased from the inner end close to the wing plate of the clamp body to the middle position and then is continuously gradually decreased from the inner end to the outer end far away from the wing plate of the clamp body.

Furthermore, the rotating body is provided with two through holes for reducing weight and braking heat dissipation of the caliper body, and the through holes correspond to the spaces on two sides of the reinforcing body respectively.

Furthermore, the rotating body is of an equal-thickness structure, the thickness of the rotating body is 5-15mm, and the rotating angle is 40-90 degrees.

Furthermore, the back of the clamp body and the body of the clamp body are integrally cast.

The utility model has the advantages that:

1. the utility model provides a car floating caliper disc brake pincers body has alleviateed pincers body structure quality under the condition that guarantees pincers body structural rigidity and intensity and do not reduce to reduce the quality of car disc brake system, and then reduced whole car quality, reduced the energy resource consumption when the car goes.

2. The utility model provides a car floating caliper disc brake pincers body, it is simple feasible to make, easily popularizes and applies.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the means of the instrumentalities and/or combinations particularly pointed out in the appended claims.

Detailed Description

The present invention will be further described with reference to the following embodiments. Wherein the showings are for the purpose of illustration only and are shown by way of illustration only and not in actual form, and are not to be construed as limiting the present patent; for a better explanation of the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

As shown in fig. 1-2, in the present embodiment, the caliper back 1 of the floating caliper disc brake caliper for an automobile is composed of a lower layer of rotating body 4 and an upper layer of reinforcement 3, and the projection of the reinforcement 3 on the rotating body 4 is W-like, that is: the caliper body comprises a caliper body caliper back 1, wherein the caliper body caliper back 1 has a structure with A, B, C radii in the same cross section, the reinforcement 3 is arranged between A, B and is a transmission path of stress borne by the caliper body when the brake system works, and the rotating body 4 is arranged between B, C to support the reinforcement 3; meanwhile, the thickness of the reinforcing body 3 protruding out of the rotator 4 is gradually increased from the inner end close to the wing plate 2 of the forceps body to the middle position and then is continuously gradually decreased outwards to the outer end far away from the wing plate 2 of the forceps body to be stopped; and the rotating body 4 is provided with two through holes 5 for weight reduction and braking heat dissipation of the caliper body, and the two through holes 5 correspond to the spaces on the two sides of the reinforcement body 3 respectively, so that the abrasion states of the brake disc and the friction block can be observed conveniently. By adopting the scheme, the clamp structure reduces the structural quality of the clamp body, is simple and feasible to manufacture and is easy to popularize and apply.

The rotating body 4 in the embodiment is of an equal-thickness structure, the thickness of the rotating body is 5-15mm, and the rotating angle is 40-90 degrees; the thickness is preferably 8mm, and the rotation angle is 45 degrees, so that the use condition can be met.

The caliper body back 1 and the caliper body in the embodiment are integrally cast. The overall rigidity of the clamp body is better.

Through simulation, fig. 3 is a CAE analysis result graph of the automobile floating caliper disc brake caliper body satisfying the deformation demand in the present embodiment, and the center deformation of the piston cavity cylinder hole is 0.158mm when the brake hydraulic pressure is 7 MPa. Fig. 4 is a CAE analysis result chart of the automobile floating caliper disc brake caliper body satisfying the stress requirement in the embodiment, and the stress is 370.2MPa when the brake hydraulic pressure is 7 MPa. The performance effect is better.

Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the scope of the claims of the present invention.
