Abstract
The utility model discloses an electromagnetic brake which comprises a brake base plate. A drive brake shoe and a driven brake shoe are oppositely arranged on the brake base plate. A brake shoe restoring spring is arranged between the drive brake shoe and the driven brake shoe. A brake pillar is installed on the brake base plate and between first end portions of the drive brake shoe and the driven brake shoe. The brake pillar is connected with a brake arm. An electromagnet is installed on the brake arm. A hand brake positioning device is arranged between the first end portions of the drive brake shoe and the driven brake shoe. The hand brake positioning device comprises a hand brake revolving shaft installed on the brake base plate in a rotation mode. One end of the hand brake revolving shaft is provided with a poking piece which stretches the drive brake shoe and the driven brake shoe open. The other end of the hand brake revolving shaft is provided with a hand brake arm. The electromagnetic brake is compact in structure, high in reliability, capable of simultaneously achieving car running brake and car parking brake and capable of greatly reducing manufacture cost.
Description
Technical field
The utility model relates to the break technical field, especially relates to a kind of electromagnetic brake.
Background technique
Drum brake is outwards to open the purpose that skidding is realized in the friction brake drum inboard by brake shoe, and that electromagnetic brake has speed of response is fast, characteristic of simple structure and more and more being used, at present, electromagnetic brake of the prior art does not generally have the parking brake parking braking function, therefore need to cooperate separately the parking brake break to use, so not only the structure of break is just not compact, and the manufacture cost of break improves greatly.
The model utility content
Technical problem to be solved in the utility model is: a kind of electromagnetic brake is provided, and compact structure, the reliability height can be realized service brake and parking braking simultaneously, manufacture cost reduces greatly.
For solving the problems of the technologies described above, the technical solution of the utility model is: electromagnetic brake, comprise braking bottom board, described braking bottom board is provided with the neck brake shoe that is oppositely arranged and from brake shoe, described neck brake shoe and be provided with brake-shoe return spring between the brake shoe, be rotatablely equipped with brake posts on the described braking bottom board, described brake posts is arranged at described neck brake shoe and between the first end of brake shoe, described brake posts is connected with brake arm, on the described brake arm electromagnet is installed, described neck brake shoe and be provided with the parking brake positioning device between the first end of brake shoe, described parking brake positioning device comprises that rotation is installed on the parking brake rotating shaft on the described braking bottom board, one end of described parking brake rotating shaft is equipped be used to strutting described neck brake shoe and from the plectrum of brake shoe, the other end of described parking brake rotating shaft is equipped with the parking brake brake arm.
Preferably, in the described parking brake rotating shaft thrust block and nut are installed, described thrust block and nut are arranged at the both sides of described braking bottom board respectively.
Preferably, described neck brake shoe and between the second end of brake shoe, be provided with slack adjuster.
Preferably, described slack adjuster comprises adjustable lever cover and the adjustable lever by being threaded, described adjustable lever cover periphery is provided with ratchet, described adjustable lever cover leans mutually with the second end of described neck brake shoe, described adjustable lever leans mutually with described the second end from brake shoe, described neck brake shoe and adjust spring from being provided with the gap between the second end of brake shoe.
Adopted technique scheme, the beneficial effects of the utility model are: be provided with the parking brake positioning device owing to the neck brake shoe of electromagnetic brake and between the first end of brake shoe, the parking brake positioning device comprises that rotation is installed on the parking brake rotating shaft on the braking bottom board, one end of parking brake rotating shaft is equipped with plectrum, the other end of parking brake rotating shaft is equipped with the parking brake brake arm, therefore this break not only can be realized service brake, and can realize parking braking, both unite two into one, structure is compacter, and manufacture cost reduces greatly.
Owing to lead brake shoe and between the second end of brake shoe, be provided with slack adjuster, when long-time use, the neck brake shoe can be adjusted brake drum and neck brake shoe and reach the braking effect of the best from the gap between the friction plate of brake shoe when making braking effect not good from brake shoe because of wearing and tearing by the ratchet of adjusting play controlling device.
