Description
Technical field
It is specially a kind of for the light-duty of light truck and middle-size and small-size car the utility model is related to brake technical field
Wedge brake.
Background technology
Currently, domestic use traditional drum brake mostly using bogie, the car of air braking system：By braking gas
Room provides brake force, then is transmitted to brake-shoe by adjusting arm, camshaft and generates brake force.Except most of car and a small amount of load-carrying
Vehicle mostly uses hand regulation arm, i.e., by manually aperiodically adjusting brake clearance using outside automatic adjusting arm.That thus brings asks
Topic is：1, there are the excessive risks for causing brake force to reduce even forfeiture in gap；2, cause the brake clearance of each wheel inconsistent,
Will appear when emergency braking brake partially, turn around, the grave dangers such as whipping；3, to the vehicle equipped with ABS, signal acquisition mistake can be caused
And implementation deviation, the normal work of ABS system is influenced, hidden danger is brought to vehicle safety.
Due to the limitation of the factors such as state's internal friction materials, cost, the brake force of disk brake can't fully meet vehicle
Brake request.Currently, the only heavy front axle in part uses domestic disk brake.
Invention content
The purpose of this utility model is to provide a kind of light-duty brakes with automatic regulating brake gap, in solution
State the problem of being proposed in background technology.
To achieve the above object, the utility model provides the following technical solutions：A kind of light wedged brake, including bottom
Plate, the self-regulated device being fixed on the bottom plate and shoes, the outside for being set to the shoes and rigidly connected with the shoes
Not uniform thickness friction plate；The self-regulated device include mandril and it is symmetrically arranged, constitute in the self-regulated device independently arranged gap from
Two voussoirs of regulating mechanism；The mandril of the self-regulated device is 12-20 degree with the axial angle of the bottom plate.
Further, the self-regulated device is secured by bolts in the bottom plate, and the shoes is fixed on described by axis pin
Bottom plate.
Further, the bottom plate uses punch welding casting and forming；The shoes use is rushed welding structure and is made.
Further, the light-duty brake further includes return spring.
Further, the light-duty brake further includes dust board.
Further, the light-duty brake is used for light truck or middle-size and small-size car.
Further, the specification of the light-duty brake is diameter 310-320mm.
Compared with prior art, the utility model has the beneficial effects that：1, the light-duty brake by brake clearance from
Gas chamber thrust is converted into brake force by dynamic modulator, and braking efficiency is high, and reaction is rapider.Required gas chamber specification is than traditional drum
Formula brake it is small, air consumption is small, save oil consumption.2, the brake clearance automatic modulator of the light-duty brake is equipped with two inner rooms
Gap automatic mechanism, and the axial angle of the mandril of self-regulated device and bottom plate is 12-20 degree, during braking return, respectively
The automatic excessive gaps eliminated between two shoes friction plates and brake drum, remain the constant setting gap of vehicle, improve system
Dynamic safety.3, using not uniform thickness friction plate, abrasion storage level and stock utilization are improved.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the side structure schematic view of the utility model.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to Fig. 1, a kind of embodiment provided by the utility model：A kind of light wedged brake is used for light truck
Or middle-size and small-size car；It is fixed on including bottom plate 1, the self-regulated device 2 being secured by bolts on the bottom plate 1, by axis pin 4 described
Shoes 3 on bottom plate 1, not uniform thickness friction plate 8；The not uniform thickness friction plate 8 be set to the outside of the shoes 3 and with it is described
Shoes 3 is rigidly connected；The self-regulated device 2 includes mandril 7 and symmetrically arranged two voussoirs 9, and described two voussoirs 9 constitute institute
State independently arranged clearance self-regulating mechanism in self-regulated device 2；The mandril 7 and the axial angle of the bottom plate 1 of the self-regulated device 2 be
12-17 degree effectively controls brake clearance in the range of setting, improves the safety of light-duty brake.
The bottom plate 1 uses punch welding casting and forming；The use of the shoes 3 is rushed welding structure and is made.
The light-duty brake further includes return spring 6, and the return spring 6 brakes return for shoes.
The light-duty brake further includes dust board 5, is effectively protected foreign matter and does not enter light-duty brake, improves light-duty system
The service life of dynamic device.
The specification of the light-duty brake is diameter 310-320mm.
The operation principle of the light-duty brake is：Wedge-type gas chamber pushes the mandril 7 of the self-regulated device 2, the top
Bar 7 pushes two voussoirs 9 to move, to which the thrust of wedge-type gas chamber is converted to hanging down to the shoes 3 by the self-regulated device 2
