Abstract
The utility model discloses a kind of brakes with anti-pollution function, including braking fuse-box and the friction plate being mounted in the braking fuse-box, rocker arm shaft mounting hole is provided on the braking fuse-box, rocker arm shaft is provided in the rocker arm shaft mounting hole, rocker arm is installed, the rocker arm shaft is connected in the rocker arm shaft mounting hole by multiple sealing bearings on the rocker arm shaft.The utility model skid resistance is small, is effectively reduced the abrasion of rocker arm shaft Yu rocker arm shaft mounting hole, while preventing muddy water that can enter by fixing clearance in braking fuse-box.
Description
Technical field
The utility model relates to brake field more particularly to a kind of brakes with anti-pollution function.
Background technique
The short distance trip of people will largely depend on electric vehicle, bicycle or motorcycle, vehicle in recent years
Brake be related to the safety rided, traditional drum brake brake mostly uses rocker arm to drive rocker arm shaft rotation, and left and right is rubbed
Pad is strutted by rocker arm shaft, and the excircle sidewall extrusion brake hub of left and right friction plate makes vehicle braking, but in the prior art, such as
Shown in Fig. 3, rocker arm shaft is directly installed on braking fuse-box, and rocker arm shaft will appear abrasion after being used for a long time, and muddy water can lead to
Crossing fixing clearance and entering braking fuse-box causes brake to lose braking effect, causes traffic accident, is based on this, designs a kind of tool
There is the brake of anti-pollution function, prevent muddy water from entering braking fuse-box, to improve the service life of brake, guarantees driver's
Safety.
Utility model content
The purpose of the utility model is to provide a kind of brake with anti-pollution function, after solution rocker arm shaft is used for a long time
It will appear abrasion, muddy water can enter the problems in braking fuse-box by rocker arm shaft fixing clearance.
In order to solve the above technical problems, the utility model adopts the following technical solution:
A kind of brake with anti-pollution function of the utility model, including brake fuse-box and be mounted in the braking fuse-box
Friction plate, be provided with rocker arm shaft mounting hole on the braking fuse-box, be provided with rocker arm shaft in the rocker arm shaft mounting hole, it is described
Rocker arm is installed, the rocker arm shaft is connected in the rocker arm shaft mounting hole by multiple sealing bearings, described to shake on rocker arm shaft
It is provided with end cover between arm and braking fuse-box, the end cover is socketed on the rocker arm shaft, and the sealed end
Lid is threadedly attached on the braking fuse-box.
Further, flexible dirt proof sleeve is set between the rocker arm and end cover, and the elasticity dirt proof sleeve is socketed in
On the rocker arm shaft, and the left and right ends of the elastic dirt proof sleeve are against the opposite face of the rocker arm and end cover respectively
On.
Further, the elastic dirt proof sleeve is set as rubber bellows.
Further, the quantity of the sealing bearing is set as two.
Compared with prior art, the advantageous effects of the utility model:
A kind of brake with anti-pollution function of the utility model is reduced by installing sealing bearing on rocker arm shaft
The abrasion of rocker arm shaft and rocker arm shaft mounting hole prevents muddy water to enter by rocker arm shaft and the abrasion gap of rocker arm shaft mounting hole
It brakes in fuse-box, while end cover and elastic dirt proof sleeve is set between rocker arm and braking fuse-box, further improve and shake
The installation sealing effect of arm axle and rocker arm shaft mounting hole.The utility model skid resistance is small, is effectively reduced rocker arm shaft and shakes
The abrasion of arm axle mounting hole, while preventing muddy water that can enter by fixing clearance in braking fuse-box.
Detailed description of the invention
The utility model is described in further detail for explanation with reference to the accompanying drawing.
Fig. 1 is the cross-sectional view for the brake that the utility model has anti-pollution function；
Fig. 2 is the partial enlarged view at the A of Fig. 1；
Fig. 3 is the mating connection schematic diagram of rocker arm shaft and rocker arm shaft mounting hole in the prior art.
Description of symbols: 1, fuse-box is braked；2, friction plate；3, rocker arm shaft mounting hole；4, rocker arm shaft；5, bearing is sealed；

Specific embodiment
As shown in Fig. 1 to 2, a kind of brake with anti-pollution function, including brake fuse-box 1 and be mounted on braking fuse-box 1
In friction plate 2, brake fuse-box 1 on be provided with rocker arm shaft mounting hole 3, rocker arm shaft 4, rocker arm are provided in rocker arm shaft mounting hole 3
Rocker arm 6 is installed, above-mentioned parts and its installation method belong to the prior art, and those skilled in the art completely can be on axis 4
Implement, details are not described herein.Muddy water can be entered by rocker arm shaft mounting hole 3 in braking fuse-box 1 in order to prevent, and is reduced and shaken
The abrasion of arm axle 4, rocker arm shaft 4 are connected in rocker arm shaft mounting hole 3 by multiple sealing bearings 5, and sealing bearing 5 reduces rocker arm shaft
Muddy water is prevented to enter in braking fuse-box 1 while 4 abrasion.
In order to further increase sealing effect, end cover 8, end cover are provided between rocker arm 6 and braking fuse-box 1
8 are socketed on rocker arm shaft 4, and end cover 8 is threadedly attached on braking fuse-box 1, between rocker arm 6 and end cover 8
Flexible dirt proof sleeve 7 is set, and elastic dirt proof sleeve 7 is socketed on rocker arm shaft 4, and the left and right ends of elastic dirt proof sleeve 7 are supported respectively
On the opposite face of rocker arm 6 and end cover 8.
In the present embodiment, elastic dirt proof sleeve 7 is set as rubber bellows, and the quantity of sealing bearing 5 is set as two.
In the prior art, the reset of rocker arm 6 generally passes through torsional spring 9 and is resetted, and torsional spring 9 is socketed in rocker arm shaft 4, torsional spring 9
Two hook ends be hooked in respectively braking fuse-box 1 and rocker arm 6 on, torsional spring 9 belongs to conventional technical means, and details are not described herein, In
In the present embodiment, in order to not influence the installation of torsional spring 9, elastic dirt proof sleeve 7 is located at the inside of torsional spring 9.
Embodiment described above is only that the preferred embodiment of the utility model is described, not to the utility model
