Abstract
The utility model discloses a hydraulic self-regulation break. The hydraulic self-regulation break comprises a brake bottom plate, wherein the brake bottom plate is provided with a leading brake shoe and a slave brake shoe which are oppositely arranged, a brake shoe return spring is arranged between the leading brake shoe and a slave brake shoe, and a hydraulic braking pump is arranged between the opposite ends of the leading brake shoe and the slave brake shoe; the two ends of the hydraulic braking pump respectively push against the end parts of the leading brake shoe and the slave brake shoe, a gap self-regulation device is arranged between the opposite end parts and comprises a regulator and a regulating shifting fork; the regulator comprises a regulating rod sleeve and a regulating rod which are connected through a thread, and ratchet wheels are arranged at the periphery of the regulating rod sleeve; and the regulating shifting fork is articulated to the slave brake shoe, the regulate shifting fork pushes against the ratchet wheels, and a shifting fork return spring is arranged between the regulating shifting fork and the leading brake shoe. The hydraulic self-regulation break provided by the utility model realizes automatic regulation of a gap between a brake drum and a friction disc, so that the braking gap arranged between the brake drum and the friction disc is always in the optimal state, the security is greatly improved, and complicated steps of manual regulation are avoided.
Description
Technical field
The utility model relates to the break technical field, especially relates to a kind of hydraulic pressure self-regulating break.
Background technique
drum type hydraulic brake is to drive brake shoe by the brake fluid press pump outwards to open the purpose that skidding is realized in the friction brake drum inboard, because drum brake is by friction catch, inevitably can cause the wearing and tearing of brake drum and friction plate, thereby the gap that causes brake drum and friction plate becomes large, the braking response time is increased, strengthen the driving risk, at present, the gap that the drum brake that uses on vehicle adopts manual tune to produce because of wearing and tearing mostly, when needs are regulated the friction gap, the personnel of needing repairing carry out manual tune at the bottom of climbing to car, so not only waste time and energy, and the bad assurance of brake clearance.
The model utility content
Technical problem to be solved in the utility model is: a kind of hydraulic pressure self-regulating break is provided, simple in structure, reliability is high, realized the automatic adjusting in brake drum and friction plate gap, make the brake clearance between brake drum and friction plate be in all the time the optimum state, greatly improve Security, avoided simultaneously the loaded down with trivial details step of regulating manually.
for solving the problems of the technologies described above, the technical solution of the utility model is: hydraulic pressure self-regulating break, 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 brake shoe, described neck brake shoe and be provided with hydraulic braking pump between an opposed end of brake shoe, the two ends of described hydraulic braking pump respectively with described neck brake shoe with lean mutually from the end of brake shoe, be provided with the clearance self-regulating engagement positions between described opposed end, described clearance self-regulating engagement positions comprises regulator and regulates shift fork, the two ends of described regulator lean mutually with described neck brake shoe with from the second end of brake shoe respectively, described regulator comprises adjustable lever cover and the adjustable lever that is threaded connection, described adjustable lever cover periphery is provided with ratchet, described adjusting shift fork is articulated in described from brake shoe, described adjusting shift fork and described ratchet offset, be provided with the shift fork Returnning spring between described adjusting shift fork and described neck brake shoe.
Preferably, described from the brake shoe the hinged hand-braking arm that is equipped with.
Adopted technique scheme, the beneficial effects of the utility model are: due to the neck brake shoe of hydraulic pressure self-regulating break and be provided with the clearance self-regulating engagement positions between the opposed end of brake shoe, realized the automatic adjusting in brake drum and friction plate gap, make the brake clearance between brake drum and friction plate be in all the time the optimum state, greatly improved Security, avoided simultaneously the loaded down with trivial details step of regulating manually, simple in structure, reliability is high.
Owing to being installed with the hand-braking arm from brake shoe, therefore, this break also has parking braking function.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation;

Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
as shown in Figure 1, hydraulic pressure self-regulating break, comprise braking bottom board 1, braking bottom board 1 is provided with the neck brake shoe 2 that is oppositely arranged and from brake shoe 3, lead brake shoe 2 and be provided with brake-shoe return spring 4 between brake shoe 3, lead brake shoe 2 and be provided with hydraulic braking pump 5 between an opposed end of brake shoe 3, the two ends of hydraulic braking pump 5 lean mutually with neck brake shoe 2 and end from brake shoe 3 respectively, be provided with the clearance self-regulating engagement positions between above-mentioned opposed end, the clearance self-regulating engagement positions comprises: regulator 6 and adjusting shift fork 7, the two ends of regulator 6 lean mutually with neck brake shoe 2 with from the second end of brake shoe 3 respectively, regulator 6 comprises adjustable lever cover 8 and the adjustable lever 9 that is threaded connection, adjustable lever cover 8 peripheries are provided with ratchet 10, regulate shift fork 7 and be articulated in from brake shoe 3, regulate shift fork 7 and offset with ratchet 10, regulate between shift fork 7 and neck brake shoe 2 and be provided with shift fork Returnning spring 11.
In addition, the hinged hand-braking arm 12 that is equipped with from the brake shoe 3 makes this break have parking braking function.
The utility model has been realized the automatic adjusting in brake drum and friction plate gap, make brake drum and neck brake shoe 2 and be in all the time the optimum state from the brake clearance between the friction plate of brake shoe 3, greatly improved Security, avoided simultaneously the loaded down with trivial details step of regulating manually, simple in structure, reliability is high.
The utility model is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done are within all dropping on protection domain of the present utility model.
