Abstract
The utility model relates to a brake, comprising a bottom plate; the bottom plate is provided with two braking shoes; one ends of the two braking shoes are hinged; a resetting device is respectively arranged among the hinged ends of the two braking shoes and the bottom plate; the resetting devices are resetting springs, and the structure is simpler; and when an automobile brakes under the special conditions of climbing a slope or being bad for the contact surface of the braking shoes and a braking drum, the resetting springs enable the hinged ends of the braking shoes to be rapidly reset, therefore, the friction of a friction pair is avoided and the service life of the friction pair is prolonged.
Description
Technical field
The utility model relates to a kind of break, belongs to field of mechanical technique.
Background technique
Drum brake is a kind of braking device that brakes to rotatablely moving, drum brake comprises base plate, base plate is provided with two brake shoes, be respectively arranged with friction plate on two brake shoes, two brake shoes, one end is hinged, two brake shoe the other ends are provided with brake pump, be provided with Returnning spring between two brake shoes, realize separately braking of brake shoe by brake pump, realize resetting of two brake shoes by Returnning spring, and be a kind of suspension structure for neck from the drum brake of shoe type, the brake pump end of brake shoe is realized resetting by Returnning spring, the brake shoe rounded end, the end that promptly suspends is realized resetting by the collision that brake shoe deadweight and brake drum rotate brake shoe, automobile is in that climbing or brake shoe and brake drum surface of contact are bad etc. when in particular cases braking, brake shoe deadweight and brake drum can not overcome frictional force between brake shoe and base plate to the striking force of brake shoe, the brake shoe rounded end can not reset, cause dragging of friction pair to rub, loss power causes the too high meeting of wheel hub temperature to occur: one, seriously stopping partially when bringing to a halt under the driving situation continuously; Two, continuously driving causes temperature constantly to raise and keeps certain hour, causes the friction pair of brake shoe to be burnt out, and it is original 1/4 that frictional force has only, and braking distance is long, causes security incident easily.
At present, some break employing " V " type elastic plectrum is stirred regulator and is come auxiliary braking hoof rounded end to reset, but the installation of " V " type plectrum is cumbersome, requires break that special structure and installing space are arranged, the structure more complicated; Elastic plectrum is softer in addition, and the power of auxiliary reset is less, can not 100% guarantees thorough brake off, and above-mentioned braking defective still has the possibility of existence; Owing to brake when driving a vehicle is more frequent, plectrum one direct acting makes the plectrum premature fatigue lose efficacy easily, shortens its working life simultaneously.
The model utility content
Problem to be solved in the utility model is at above problem, provide a kind of simple in structure, brake shoe is resetted fast, thereby prolong the friction pair break in working life.
For addressing the above problem, the technological scheme that the utility model adopted is: a kind of break, comprise base plate, and described base plate is provided with two brake shoes, one end of two brake shoes is hinged, it is characterized in that: be respectively equipped with resetting means between the rounded end of described two brake shoes and the base plate.
As further improvement in the technical proposal:
Described resetting means is a Returnning spring.
The utility model is taked above technological scheme, has the following advantages: Returnning spring is set respectively between the rounded end of two brake shoes and the base plate, and relatively simple for structure; When automobile in that climbing or brake shoe and brake drum surface of contact are bad etc. when in particular cases braking, this Returnning spring resets the brake shoe rounded end rapidly, thereby has avoided the friction of friction pair, has prolonged the working life of friction pair.
The utility model is described in further detail below in conjunction with drawings and Examples.
