Description
Technical field
The utility model discloses a kind of drum to stop, the drum referred more particularly to for electric motor car is stopped.
Background technique
It is utilize brake shoes to contact brake drum Inner edge when braking that drum is stopped, and the frictional force produced by contact is to suppress tyre rotation to reach brake object.Traditional electric motor vehicle drum brake is primarily of parts compositions such as braking top, shoe plate group, cam, brake lever, and cam and fixing pin are point-blank.Certain angle is rotated by brake lever band moving cam, shoe plate group is expanded outwardly, thus reach brake object, traditional cam is vertically arranged, even if rotate larger angle, the scope that shoe plate group expands outwardly is also very micro-, is reflected in practical application, needs to hold more greatly the power of stopping and just can reach required braking effect.Moreover owing to rotating larger angle, make friction plate frictional wear serious, the friction plate life-span has a strong impact on.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of drum that can reduce skidding stroke and stops.
In order to solve the problems of the technologies described above, the utility model provides a kind of drum and stops, form primarily of lid of stopping, shoe plate group, brake lever and cam, cam is fixedly connected with brake lever and can with brake lever at lid rotation with in surface of stopping, shoe plate group upper end is fixed on to stop by fixing pin and is covered, and shoe plate group periphery is provided with friction plate, and described shoe plate group top and bottom are respectively equipped with return spring, described cam and the diameter line covered of stopping corresponding to its position are an angle, and this angle is 10-35 °.
As further improvement of the utility model, described cam and the diameter line covered of stopping corresponding to its position are an angle, and this angle is 18-30 °.
As further improvement of the utility model, described cam and the diameter line covered of stopping corresponding to its position are an angle, and this angle is 25 °.
Further improve as of the present utility model, described shoe plate group lower end is respectively equipped with fixed tabs, and fixed tabs is fitted respectively with the left and right both sides of the cam under static state respectively.
Adopt said structure, its beneficial effect is: this drum is stopped by the cam inclination 10-35 ° arranged by conventional vertical, during brake, cam rotates less angle can make the generation of shoe plate group compared with the separation of large scale, namely stop compared to traditional drum, reduce the braking distance of brake, leave stroke space for subsequent use.Due to the reduction of the braking distance of brake, friction plate frictional wear is significantly reduced, extends the working life of brake greatly.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model drum is stopped.
Fig. 2 is that traditional drum is stopped structural representation.
In figure: 1-stops lid, 2-shoe plate group, 3-brake lever, 4-cam, 5-fixing pin, 6-friction plate, 7-return spring, 8-fixed tabs.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Embodiment one:
As Fig. 1, shown in 2, a kind of drum is stopped, primarily of lid 1 of stopping, shoe plate group 2, brake lever 3 and cam 4 form, cam 4 is fixedly connected with brake lever 3 and can with brake lever 3 at lid 1 rotation with in surface of stopping, shoe plate group 2 upper end is fixed on by fixing pin 5 and is stopped on lid 1, shoe plate group 2 periphery is provided with friction plate 6, described shoe plate group 2 top and bottom are respectively equipped with return spring 7, described cam 3 is an angle with the diameter line of the lid 1 of stopping corresponding to its position, this angle is 10-35 °, described shoe plate group 2 lower end is respectively equipped with fixed tabs 8, fixed tabs 8 respectively with the left side of the cam 3 under static state, fit respectively in right both sides.
To be tilted 10-35 ° by the cam 4 that conventional vertical is arranged, can be learnt by geometry principle, the cam 4 be obliquely installed rotates less angle can make shoe plate group 2 produce separation compared with large scale.Laboratory data shows, shoe plate group 2 is separated same distance each other, the angle that the cam 4 be obliquely installed rotates is the 1/2-1/4 of cam 4 rotation angles vertically arranged, thus the utility model is stopped compared to traditional drum, when reaching same braking effect, skidding stroke reduces greatly, and the required power of stopping of manually holding reduces greatly.Thus, this drum is used to stop safety and reliability.Due to the reduction of the braking distance of brake, friction plate frictional wear is significantly reduced, extends the working life of brake greatly.
Embodiment two:
Described cam 3 is an angle with the diameter line of the lid 1 of stopping corresponding to its position, and this angle is 18-30 °, can be learnt by geometry principle, and the cam 4 be obliquely installed rotates less angle can make shoe plate group 2 produce separation compared with large scale.Laboratory data shows, shoe plate group 2 is separated same distance each other, the angle that the cam 4 be obliquely installed rotates is the 1/3-1/4 of cam 4 rotation angles vertically arranged, thus the utility model is stopped compared to traditional drum, when reaching same braking effect, skidding stroke reduces greatly, and the required power of stopping of manually holding reduces greatly.Thus, this drum is used to stop safety and reliability.Due to the reduction of the braking distance of brake, friction plate frictional wear is significantly reduced, extends the working life of brake greatly.
Embodiment three:
Described cam 3 is an angle with the diameter line of the lid 1 of stopping corresponding to its position, and this angle is 25 °, can be learnt by geometry principle, and the cam 4 be obliquely installed rotates less angle can make shoe plate group 2 produce separation compared with large scale.Laboratory data shows, shoe plate group 2 is separated same distance each other, the angle that the cam 4 be obliquely installed rotates is 1/4 of cam 4 rotation angles vertically arranged, thus the utility model is stopped compared to traditional drum, when reaching same braking effect, skidding stroke reduces greatly, and the required power of stopping of manually holding reduces greatly.Thus, this drum is used to stop safety and reliability.Due to the reduction of the braking distance of brake, friction plate frictional wear is significantly reduced, extends the working life of brake greatly.
Any employing and the similar drum designed by technical characteristics of the utility model are stopped and will be fallen within protection domain of the present utility model.
