Abstract
The utility model discloses a brake drum dynamic balance weight-removing groove structure mainly includes brake drum, weight-removing groove structure, arch, and design processing weight-removing groove structure on the brake drum external diameter sets up in the arch of brake drum circumference to weight-removing groove structure is annular grooving form. The utility model reduces the time consumption for processing the brake drum, reduces the processing cost, and solves the problems of long time consumption and high cost for processing the brake drum caused by too many times of punching processing; the brake drum is far away from the friction surface machining of the brake drum, the influence of the machining on the roundness of the friction surface is reduced to the maximum extent, the problem of poor consistency of form and position tolerance of the friction surface caused by the fact that the weight reduction position of the brake drum is too close to the friction surface due to dynamic balance is solved, and the problems of clamping stagnation, uneven friction of a friction plate and the like easily occurring in the whole vehicle test are avoided.
Description
Technical Field
The utility model relates to a field of brake drum, concretely relates to brake drum dynamic balance weight-removing groove structure.
Background
The conventional dynamic balance de-weighting of the brake drum uses a structure for punching holes in an inner groove, and usually 6-8 holes are needed to be punched for completing the dynamic balance de-weighting, so that the punching process has more times, long processing time and high cost. In addition, the holes are punched to be close to the inner side friction surface of the brake drum, and the problems of poor roundness and jumping consistency of the friction surface and the like caused by punching for multiple times are solved.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a novel brake drum dynamic balance weight-removing groove structure.
The purpose of the utility model is accomplished through following technical scheme: the dynamic balance weight-removing groove structure of the brake drum mainly comprises the brake drum, a weight-removing groove structure and a protrusion, wherein the weight-removing groove structure is designed and processed on the outer diameter of the brake drum, the weight-removing groove structure is arranged in the protrusion on the circumference of the brake drum, and the weight-removing groove structure is in an annular groove cutting form.
The utility model has the advantages that: the utility model reduces the time consumption for processing the brake drum, reduces the processing cost, and solves the problems of long time consumption and high cost for processing the brake drum caused by too many times of punching processing; the brake drum is far away from the friction surface machining of the brake drum, the influence of the machining on the roundness of the friction surface is reduced to the maximum extent, the problem of poor consistency of form and position tolerance of the friction surface caused by the fact that the weight reduction position of the brake drum is too close to the friction surface due to dynamic balance is solved, and the problems of clamping stagnation, uneven friction of a friction plate and the like easily occurring in the whole vehicle test are avoided.

Description of reference numerals: the brake drum comprises a brake drum 1, a punching structure 2, a weight-removing groove structure 3 and a protrusion 4.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the attached drawings, the dynamic balance weight-reducing groove structure of the brake drum mainly comprises the brake drum 1, the weight-reducing groove structure 3 and a protrusion 4, wherein the weight-reducing groove structure 3 is designed and machined on the outer diameter of the brake drum 1, the weight-reducing groove structure 3 is arranged in the protrusion 4 on the circumference of the brake drum 1, and the weight-reducing groove structure 3 is in an annular groove cutting form. The weight-removing groove structure 3 reduces the complexity of a processing process while ensuring dynamic balance, and changes multiple times of processing into one-time forming, thereby ensuring the consistency of products and particularly realizing low quality performance failure rate of brake drums in the same batch.
The utility model discloses a theory of operation: when the drum brake is used for braking, a brake shoe and a cylindrical friction surface of the brake drum 1 are rubbed, and the brake drum 1 is greatly stressed at the moment, so that the brake drum 1 is easy to have the problem of low joint rate of the friction surface and a friction plate in the braking process, and the problems of clamping stagnation, poor return and the like of the friction plate can be caused if the form and position tolerance such as roundness, coaxiality and the like of the friction surface of the brake drum 1 is poor at the moment. In the prior technical scheme, the cut-off part of the dynamic balance weight-removing hole of the brake drum 1 is close to the friction surface, and the process of punching for multiple times is adopted, so that the probability of poor form and position tolerance, particularly poor roundness of the friction surface of the brake drum 1 is increased, and the dynamic balance annular weight-removing groove is formed in the outer side of the brake drum 1, so that the friction surface can be far away from the friction surface for processing on the basis of one-step forming, the jamming occurrence rate of the brake drum 1 is reduced, the product processing time is reduced, the processing process cost is reduced, the occurrence of jamming and incapability of returning of a brake shoe is restrained, and the problems of large dragging, poor stability and the like of a drum brake are fundamentally solved.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
