Abstract
The utility model discloses an automotive brake comprising a brake drum, a couple of brake shoes disposed inside the brake drum, brake discs installed at back sides of the brake shoes, return springs, two ends of each of which are respectively hooked on the two brake shoes, and a couple of distance adjusting mechanisms connected between the two brake shoes; and each distance adjusting mechanism comprises a piston oil cylinder, a couple of pistons disposed in the piston oil cylinder, and thread structures for connecting the pistons and the brake shoes. Brake reliability and vehicle safety performance are increased by the automotive brake, and the automotive brake is high in practicality and worth to be popularized.
Description
Technical field
The utility model relates to the braking technology field of vehicle, relates in particular to a kind of automotive brake.
Background technique
At present, in the braking technology of vehicle, in the time of brake, the brake shoe of drum brake outwards opens, and friction brake drum inner side, reaches the object that driving is braked.And the complex structure of existing automotive brake reacts sensitive not, the effect of braking is bad.
Model utility content
The utility model, in order to solve the above-mentioned deficiency of prior art, has proposed a kind of automotive brake.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of automotive brake, comprise brake drum, be placed in a pair of brake shoe of inside brake drum, the brake block that is arranged on the brake shoe back side, two ends be hooked on respectively the return spring on two brake shoes and be connected in a pair of distance adjustor between two brake shoes, described distance adjustor comprises piston oil-cylinder, is located at pair of pistons and the worm structure that is connected described piston and described brake shoe in piston oil-cylinder.
Further, described worm structure comprises and is fixed on the screw of described brake shoe and is located at the screw on piston.
Compared with prior art, the piston oil-cylinder that the utility model adopts drives the work of two brake shoes, wherein, what the piston of piston oil-cylinder adopted is worm structure docking brake shoe, such structure is more stable, and brake response is also sensitiveer, has improved retardation efficiency, and total is simple, practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, model utility is described in detail.
As shown in Figure 1, the automotive brake the utility model proposes, comprise brake drum 1, brake drum 1 inside is provided with a pair of brake shoe 2, the back side of brake shoe 2 is fixedly mounting brake block 3, between two brake shoes 2, hook between return spring 4, two brake shoe 2 two ends and is designed with a pair of distance adjustor, and distance adjustor comprises piston oil-cylinder 5, is located at the interior pair of pistons 6 of piston oil-cylinder 5 and the worm structure that is connected described piston 6 and brake shoe 2.Worm structure comprises and is fixed on the screw 7 of brake shoe 2 and is located at the screw 8 on piston.
In the utility model, when piston oil-cylinder is worked, pour brake fluid, piston is to two Slideslips, and brake shoe 2 expands outwardly, and the brake block 3 on brake shoe 2 is rubbed mutually with brake drum 1, reaches the object of brake.
Wherein, between brake shoe 2 and piston 6, adopt worm structure to dock, make total more firm, thereby make braking effect also sensitiveer.
Above-described embodiment has only been expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the utility model patent and protection domain should be as the criterion with appended claims.
