Description
Technical field
The utility model relates to brakes more particularly to a kind of Hydraulic Double to lead shoe drum clearance self-regulating brake.
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, provides a kind of Hydraulic Double neck shoe drum clearance self-regulating system
Dynamic device.
Technical solution used by the utility model is as follows:
A kind of Hydraulic Double neck shoe drum clearance self-regulating brake, including brake feet, wheel cylinder and brake-shoe, braked wheel
Cylinder includes cylinder body and piston, and pistons end connection adjusts bolt, and piston is bolted brake-shoe by adjusting, on the outside of brake-shoe
Friction plate is connected, the adjusting is bolted adjusting ratchet, and the adjusting ratchet side setting adjusts shift plate, the adjusting shift plate
It is rotatably connected on cylinder body by positioning bolt, the adjusting shift plate connects return spring, and the return spring other end connects self-regulated
Support plate, the self-regulated support plate connects piston, and self-regulated support plate also sets up the supported end that bearing adjusts shift plate.
As a further improvement of the above technical scheme:
Support slot is arranged in the supported end of told self-regulated support plate, and locating slot is arranged in the adjusting shift plate of cooperation.
The wheel cylinder is oil cylinder, and the wheel cylinder connects master cylinder.
The beneficial effects of the utility model are as follows: the Hydraulic Double leads shoe drum clearance self-regulating brake, is mounted on braking
In drum, wheel cylinder can drive self-regulated support plate to move while driving brake-shoe movement to be braked, and be self-regulated support plate
It can be driven by return spring and adjust shift plate rotation, adjusting ratchet wheel can be driven by adjusting shift plate, adjusting ratchet wheel is
Bolt can be made to adjust by screw thread to external-adjuster, to compensate gap between brake-shoe and brake drum automatically, make brake-shoe and system
Dynamic drum gap average value remains in the reasonable scope, it is ensured that brake works normally.

Specific embodiment
With reference to the accompanying drawing, illustrate the specific embodiment of the present embodiment
As shown in Figures 1 to 4, the Hydraulic Double neck shoe drum clearance self-regulating brake of the present embodiment, including brake feet 1,
Wheel cylinder 3 and brake-shoe 4, wheel cylinder 3 include cylinder body 31 and piston 32, and the connection of 32 end of piston adjusts bolt 33, and living
Plug 32 connects brake-shoe 4 by adjusting bolt 33, connects friction plate 41 on the outside of brake-shoe 4, adjusts the connection of bolt 33 and adjusts ratchet
331, it adjusts the setting of 331 side of ratchet and adjusts shift plate 5, adjust shift plate 5 and be rotatably connected on cylinder body 31 by positioning bolt 51, adjusted
It saving shift plate 5 and connects return spring 52,52 other end of return spring connects self-regulated support plate 6, and self-regulated support plate 6 connects piston 32,
Told self-regulated support plate 6 adjusts the supported end of shift plate 5 close to the setting bearing of 5 one end of shift plate is adjusted, and opens up support slot on supported end
61, locating slot 53 is set in the adjusting shift plate 5 of cooperation, guarantees self-regulated support plate 6 and adjust shift plate 5 precisely to support, wheel cylinder 3
For oil cylinder, wheel cylinder 3 connects master cylinder.
The Hydraulic Double neck shoe drum clearance self-regulating brake is in use, be mounted in brake drum, and master cylinder is to braking
When 3 fuel feeding of wheel cylinder pressurizes, high oil pressure pushes piston 32 to move out in cylinder body 31, and piston 32 can drive brake-shoe 4 to outward transport
Dynamic, i.e., 32 can be braked by the friction plate 41 in 4 outside of brake-shoe with brake drum compression, and piston will drive during stretching out
Self-regulated support plate 6 moves out, and can be pulled by return spring 52 and adjust shift plate 5 and rotate around positioning bolt 51, and with rubbing
The moving distance of the continuous abrasion of pad 41, piston 32 increases, then adjusts 5 rotational angle of shift plate and constantly become larger, and dials until adjusting
Plate 5, which drives, adjusts the rotation of ratchet 331, and adjusting the rotation of ratchet 331 can make to adjust by screw thread bolt 33 to external-adjuster, can make
The brake-shoe 4 of two sides moves out, and brake-shoe 4 and brake drum gap average value can be made to remain in the reasonable scope, it is ensured that
Brake works normally, and when 32 retracted for clearance of piston, and self-regulated support plate 6 can be driven to reset, and is supported by self-regulated support plate 6
Shift plate 5 is adjusted, can make to adjust the reset of shift plate 5.
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.
