Technical Field

The invention relates to the technical field of brake pads, in particular to a novel drum brake.

Background

The drum brake is fixed with the tire and rotates at the same speed. When braking, the Brake Shoes (Brake Shoes) are pushed by hydraulic pressure to contact the inner edge of the Brake drum, and the friction force generated by the contact is used to restrain the rotation of the tire so as to achieve the purpose of braking. The drum brake consists of a brake bottom plate, a brake cylinder, a brake shoe and other relevant connecting rods, a spring, a pin nail and a brake drum. Currently, the wheel is only commonly adopted for front and rear wheels. The drum brake has low cost and higher absolute braking force, and is widely applied to front and rear wheels of a vehicle related to the drum brake. Brake block one slice in current market takes shape, traditional drum is stopped and is mostly not had waterproof construction, so that outside water very easily through the drum lid of stopping flow in the drum circle of stopping, cause various serious harm to the part in the drum circle of stopping, it can influence brake sensitivity and brake performance like this to go the brake leather block surface and produce the water film easily to go in rainy day, brake block one slice takes shape and at the easy laying dust in-process brake leather block surface of going, can influence the brake leather block and brake performance when braking and can produce abnormal sound and influence.

To solve the above-mentioned drawbacks, we propose a new drum brake for this purpose.

Disclosure of Invention

The invention aims to provide a novel drum brake to solve the problems in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a novel drum is stopped, includes two semi-circular brake hooves, and is two sets of the outside round of semi-circular brake hoof is connected with the brake leather slab respectively, the upper end middle part of brake leather slab is equipped with the fretwork mouth, and is two sets of through spring coupling between the semi-circular brake hoof.

As a further optimization of the technical scheme, the novel drum brake is characterized in that the springs are arranged in two groups and are respectively connected to the upper ends and the lower ends of the two semicircular brake shoes.

As further optimization of the technical scheme, the novel drum brake is characterized in that the edge part of the upper end of the semicircular brake shoe is provided with a connecting lug.

As further optimization of the technical scheme, the novel drum brake is characterized in that the semicircular brake shoe and the connecting lug are integrally formed.

As further optimization of the technical scheme, the hollow-out opening accounts for 25% -50% of the total area of the brake leather sheet.

Compared with the prior art, the invention has the beneficial effects that: the invention changes the traditional brake pad structure, improves the brake sensitivity and the brake performance, reduces dust accumulation and avoids abnormal sound generated in the brake process; the middle part of the brake leather sheet is provided with a hollow-out opening which accounts for 25-50% of the area of the brake leather sheet, so that the braking distance can be shortened, and the braking performance is greatly improved; the positions of the hollow holes can be used for removing water when the vehicle is driven in rainy days; the fretwork mouth position is better to go dirt, reduces the carbon deposit, reduces the brake sound, improves brake leather sheet life, has changed the structure setting that traditional brake leather sheet one piece was formed, has solved and has gone the easy water film that produces in brake leather sheet surface, the easy dust deposit in the in-process brake leather sheet surface of going in rainy day, can abnormal sound and brake performance when the brake leather sheet braking that leads to.

In the description of the present invention, unless otherwise specified, the terms "upper", "lower", "left", "right", "front", "rear", "top", "bottom", and the like, indicate orientations or state relationships based on the orientations or state relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that a referred mechanism or component must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a novel drum is stopped, includes two semi-circular brake hooves 2, and is two sets of semi-circular brake hooves 2's outside round is connected with brake skin 1 respectively, brake skin 1's upper end middle part is equipped with fretwork mouth 4, and is two sets of connect through spring 3 between the semi-circular brake hooves 2.

Specifically, the springs 3 are arranged in two groups and are respectively connected to the upper ends and the lower ends of the two semicircular brake shoes 2, and the upper ends and the lower ends of the two semicircular brake shoes 2 are connected through the springs 3; specifically, the edge part of the upper end of the semicircular brake shoe 2 is provided with a connecting lug which is better connected with the other group of semicircular brake shoes 2; specifically, the semicircular brake shoe 2 and the connecting lug are integrally formed, so that production and manufacturing are facilitated. Specifically, the hollowed-out openings 4 account for 25% -50% of the total area of the brake pad 1, so that water and dust can be removed quickly and effectively, the braking distance can be shortened, and the braking performance can be improved.

Specifically, during the use, change traditional brake block structure, be equipped with fretwork mouth 4 on brake skin 1, can prevent effectively that water from getting into semi-circular brake hoof 2's inside, when water gets into the gap from semi-circular brake hoof 2, water can flow down owing to be equipped with fretwork mouth 4 on through brake skin 1 from the dead weight, can not ponding, effectively play hydrophobic, the water conservancy diversion effect, and is same, can also play the effect of separating to dust, dust can drop from fretwork mouth 4, and once more, can also shorten brake stroke.

In summary, the following steps: the brake sensitivity and the brake performance can be improved, dust accumulation is reduced, and abnormal sound is avoided in the brake process; the middle part of the brake leather sheet 1 is provided with the hollow-out opening 4 which occupies 25-50% of the area of the brake leather sheet 1, so that the braking distance can be shortened, and the braking performance is greatly improved; in addition, the hollow-out opening 4 is formed in the middle of the brake leather sheet 1 and occupies 25% -50% of the area of the brake leather sheet 1, so that water can be removed from the position of the hollow-out opening 4 when the bicycle is driven in rainy days; and thirdly, the middle part of the brake leather sheet 1 is provided with a hollow-out opening 4, the hollow-out opening occupies 25% -50% of the area of the brake leather sheet 1, the position of the hollow-out opening can better remove dust, reduce carbon deposition, reduce brake noise and prolong the service life of the brake leather sheet.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
