Abstract
The utility model provides a novel brake shoe, is including installing the brake shoe board on the braking piece, be provided with the last web and the lower web that are parallel to each other on the brake shoe board, its characterized in that: the outer sides of the upper web plate and the lower web plate are fixed with the surface of the brake shoe plate through reinforcing ribs respectively, weight reducing grooves are formed in the side plate walls of the upper web plate and the lower web plate, and the weight reducing grooves are located between the adjacent reinforcing ribs. The utility model has the advantages of high strength, low production cost, convenient processing and long service life.
Description
Technical Field
The utility model relates to the field of automobile parts, in particular to a novel brake shoe.
Background
The brake shoe is a part which is pushed outwards by the action of a brake cam or a push rod and expands and presses the brake drum to brake, is arranged on the brake drum, and is one of key parts in an automobile brake system. The brake shoe is a friction coupling of a drum brake, and should have a stable friction coefficient in addition to strength and rigidity required as a member. The operation principle of the brake shoe is that when a brake is stepped on, two half-moon-shaped brake shoes expand under the action of a brake wheel cylinder to support the brake shoe, and the brake shoe drives the connected brake pad to rub the inner wall of the brake drum, so that the brake shoe has the function of reducing speed or stopping. However, the brake shoes on the market are often severely worn due to low strength, so that the service life of the brake shoes is short, the running time is short, and the production cost is increased.
Disclosure of Invention
The utility model aims to overcome the defects and shortcomings of the prior art and provide a novel brake shoe which is high in strength, low in production cost, convenient to process and long in service life.
In order to achieve the above purpose, the technical solution of the utility model is as follows: the utility model provides a novel brake shoe, is including installing the brake shoe board on the braking piece, be provided with the last web and the lower web that are parallel to each other on the brake shoe board, its characterized in that: the outer sides of the upper web plate and the lower web plate are fixed with the surface of the brake shoe plate through reinforcing ribs respectively, weight reducing grooves are formed in the side plate walls of the upper web plate and the lower web plate, and the weight reducing grooves are located between the adjacent reinforcing ribs.
The reinforcing ribs are in irregular right-angle shapes.
And the upper web plate and the lower web plate are both provided with braking holes.
The brake shoe plate, the web plate and the lower web plate are of an integrally formed structure.
Compared with the prior art, the utility model has the following advantages:
1. compared with a welding brake shoe, the brake shoe has better overall performance and simpler process, and the overall mechanical strength of the brake shoe can be greatly improved and the service life of the device can be prolonged no matter the brake shoe plate, the web plate and the lower web plate are integrally formed into an integrally formed structure or the reinforcing ribs are arranged between the upper web plate, the lower web plate and the brake shoe plate.
2. The weight-reducing grooves are formed in the upper web plate and the lower web plate between the adjacent reinforcing ribs, so that the weight of the device can be reduced under the condition that the overall strength is not reduced, the material loss of the device can be reduced, and the production cost is reduced.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Fig. 2 is a top view of the present invention.
Fig. 3 is a side view of the present invention.
In the figure: the brake block comprises a brake block 1, a brake shoe plate 2, an upper web plate 3, a lower web plate 4, reinforcing ribs 5, weight reduction grooves 6 and brake holes 7.
Detailed Description
The present invention will be described in further detail with reference to the following description and embodiments in conjunction with the accompanying drawings.
Referring to fig. 1-3, a novel brake shoe comprises a brake shoe plate 2 installed on a brake pad 1, wherein an upper web 3 and a lower web 4 which are parallel to each other are arranged on the brake shoe plate 2, brake holes 7 are installed on the upper web 3 and the lower web 4, the brake shoe plate 2, the upper web 3 and the lower web 4 are of an integrally formed structure, the outer sides of the upper web 3 and the lower web 4 and the surface of the brake shoe plate 2 are fixed together through irregular right-angle-shaped reinforcing ribs 5, weight reduction grooves 6 are formed in the side plate walls of the upper web 3 and the lower web 4, and the weight reduction grooves 6 are located between the adjacent reinforcing ribs 5.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
