Technical field
The utility model relates to brake more particularly to a kind of automobile hydraulic self energizing effort drum type clearance self-regulating brakes.
Background technique
Automotive brake is constantly worn due to friction plate in use, the gap between brake-shoe and brake drum by
Gradual change is big, influences the braking effect of vehicle.User is required to carry out manual setting to brake clearance at this time.Due to road conditions and use
The factors such as habit, friction plate abrasion degree is different, is not reaching the time required on operation instructions or fare register friction
Piece has worn out seriously, and user is still unaware, has brought great hidden danger to traffic safety.Simultaneously because between manually adjusting
The process of gap is quite cumbersome, the more difficult independent operation of ordinary user.
Utility model content
The applicant is directed to disadvantage mentioned above, has carried out Improvement, provide a kind of automobile hydraulic self energizing effort drum type clearance from
Adjust brake.
Technical solution used by the utility model is as follows:
A kind of automobile hydraulic self energizing effort drum type clearance self-regulating brake, including back-plate also connect on the back-plate
Wheel cylinder is connect, the wheel cylinder two sides connect brake-shoe, and brake-shoe connects friction plate, and the back-plate is located at braked wheel
Fulcrum post is connected on the upside of cylinder, the fulcrum post connects two brake-shoes by return spring, and two brake-shoes are far from wheel cylinder
One end by regulating mechanism connect, the regulating mechanism include be threadedly coupled adjusting bolt and adjusting nut, the adjusting
Connection adjusts ratchet on nut, adjusts the setting of ratchet side and adjusts shift plate, the adjusting shift plate is rotatably connected on by straight pin
It on the brake-shoe of side, adjusts shift plate side and is supported by torsional spring, and adjust shift plate and be also connected with driving spring, driving spring connection
Drawstring, drawstring is around the adjusting guide holder and bearing pin connection on the side brake-shoe.
As a further improvement of the above technical scheme:
The attachment base of drawstring one end setting connection driving spring, the attachment base include connecting hole and spring guiding
Slot.
The wheel cylinder is oil cylinder, and the wheel cylinder connects master cylinder.
The beneficial effects of the utility model are as follows: the automobile hydraulic self energizing effort drum type clearance self-regulating brake is mounted on
In brake drum, when wheel cylinder drives brake-shoe to be braked, while adjusting shift plate can be pulled to overcome torsional spring by drawstring
Elastic force is rotated around straight pin, can be rotated by adjusting plectrum driving pawl and adjusting nut, adjusting nut rotation can pass through
Screw drive adjusts bolt and moves out, to compensate gap between brake-shoe and brake drum automatically, makes brake-shoe and brake drum
Gap average value remains in the reasonable scope, it is ensured that brake works normally.
Detailed description of the invention
Fig. 1 is the top view of the automobile hydraulic self energizing effort drum type clearance self-regulating brake of the utility model.

Specific embodiment
With reference to the accompanying drawing, illustrate the specific embodiment of the present embodiment
As shown in Figure 1 and Figure 2, the automobile hydraulic self energizing effort drum type clearance self-regulating brake of the present embodiment, including back-plate
1, wheel cylinder 3 is also connected on back-plate 1, wheel cylinder 3 is oil cylinder, and wheel cylinder 3 connects master cylinder, wheel cylinder 3
Two sides connect brake-shoe 4, and brake-shoe 4 connects friction plate 41, and back-plate 1 is located at connection fulcrum post 5 on the upside of wheel cylinder 3, branch
5 are consigned by two brake-shoes 4 of connection of return spring 51, two brake-shoes 4 pass through regulating mechanism far from one end of wheel cylinder 3
6 connections, regulating mechanism 6 include the adjusting bolt 61 and adjusting nut 62 being threadedly coupled, and connection adjusts ratchet on adjusting nut 62
621, it adjusts the setting of 621 side of ratchet and adjusts shift plate 63, adjust the braking that shift plate 63 is rotatably connected on side by straight pin 631
It on hoof 4, adjusts 63 side of shift plate and is supported by torsional spring 64, and adjust shift plate 63 and be also connected with driving spring 65, driving spring 65 is logical
72 connection stay cord 7 of attachment base is crossed, attachment base 72 includes connecting hole 721 and spring guide groove 722, the connection driving bullet of connecting hole 721
The hook of spring 65, spring guide groove 722 guarantee to remain consistent with 7 direction of drawstring when driving spring 65 stretches, prevent from driving
65 discontinuity of spring causes 65 transposition of drawstring 7 and driving spring, and drawstring 7 is around the adjusting guide holder on the side brake-shoe 4
71 connect with fulcrum post 5.
The automobile hydraulic self energizing effort drum type clearance self-regulating brake is in use, be mounted in brake drum, master cylinder pair
The pressurization of 3 fuel feeding of wheel cylinder, can be driven two sides brake-shoe 4 and is flared out, be adjacent to brake drum and rotate with brake drum, work as brake-shoe
When 4 contact fulcrum post 5, that is, braking is generated, in the process, since brake-shoe 4 opens, the adjusting guide holder 71 on brake-shoe 4
It moves out, can be held by drawstring 7 and driving spring 65 and adjust shift plate 63, when pulling force overcomes the torsion of adjusting 63 side of shift plate
The elastic force of spring 64 can pull and adjust shift plate 63 around the rotation of straight pin 631, when the gap between brake-shoe 4 and brake drum reaches
When certain design value, adjusts shift plate 63 and adjust the movement of 621 engagement place of ratchet greater than a tooth pitch, start to stir one at this time
Tooth makes adjusting nut 62 turn over the angle of a tooth, so that adjusting bolt 61 extends certain distance, 4 outer diameter of brake-shoe accordingly increases
Big certain value, this process play gap adjustment compensation effect, it is ensured that brake clearance guarantees braking in normal range of operation
Device works normally.
Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model
Range is referring to claim, and without prejudice to the basic structure of the utility model, the utility model can make any shape
The modification of formula.
