Abstract
The invention discloses a brake device and particularly relates to a brake down pump. According to the brake down pump, synchronous braking of two brake pads can be effectively guaranteed, the production and use cost is reduced, and installation is convenient. The brake down pump comprises a pump body, oil cylinders and the brake pads. The oil cylinders comprise the first oil cylinder and the second oil cylinder. An oil inlet and an exhaust hole are formed in the pump body and formed between the first oil cylinder and the second oil cylinder. The oil inlet is connected with the first oil cylinder and the second oil cylinder through an oil inflow pipe. The exhaust hole is connected with the first oil cylinder and the second oil cylinder through an exhaust pipe. The height, relative to the pump body, of the exhaust hole is larger than that, relative to the pump body, of the oil inlet.

Background technology
The lower pump of brake is a kind of device utilizing hydraulic drive to reach to brake purpose, is widely used in
In braking device for motor vehicle；Under existing brake, pump includes the pump housing, oil cylinder and brake block, oil cylinder
Including the first oil cylinder and the second oil cylinder, brake block includes first brake sheet and the second brake block, the
One oil cylinder and the second oil cylinder are connected with first brake sheet and the second brake block hydraulic drive respectively, pump
It is provided with fuel feed hole and steam vent, fuel feed hole and steam vent on body and is separately positioned on the two of the pump housing
Side, and communicate with the first oil cylinder and the second oil cylinder respectively；In braking procedure, brake fluid is from entering
Oilhole enters the first oil cylinder, subsequently enters the second oil cylinder, and is discharged in steam vent by air,
And the first oil cylinder and the second oil cylinder hydraulic drive first brake sheet and the second brake block respectively, carry out
Braking；, there is brake fluid and successively respectively enter the first oil cylinder and the second oil cylinder in this mode of braking,
And then cause nonsynchronous problem of braking, not only reduce braking quality, and make under brake
The production of pump and use cost increase, and install inconvenience.
Summary of the invention
For solving above-mentioned technical problem, the present invention provides one that two brake blocks can be effectively ensured
Synchronous brake, reduces and produces and use cost, installs the lower pump of the most conveniently brake.
Pump under the brake of the present invention, including the pump housing, oil cylinder and brake block, oil cylinder includes the first oil
Cylinder and the second oil cylinder, the pump housing is provided with fuel feed hole and steam vent, described fuel feed hole and steam vent
Being arranged between described first oil cylinder and the second oil cylinder, described fuel feed hole passes through oil inlet pipe and institute
Stating the first oil cylinder and the second oil cylinder is connected, described steam vent is by exhaustor and described first oil cylinder
Being connected with the second oil cylinder, the height of the most described pump housing of described steam vent is more than described fuel feed hole
The height of the pump housing relatively.
Further, described steam vent being additionally provided with vent cap, described vent cap is installed
On described steam vent, one end of described vent cap is by connecting outside band and described steam vent
Side is connected.
Further, described brake block includes first brake sheet and the second brake block, the first oil cylinder
It is connected with first brake sheet and the second brake block hydraulic drive respectively with the second oil cylinder, described first
The side of brake block and the second brake block relative wheel is provided with friction plate, described friction plate bag
Including brake portion and guide part, described guide part is positioned at the both sides in described brake portion, described guide part
More than 120 ° and it is less than 150 ° with the angle of friction part.
Further, described guide part is 135 ° with the angle in described brake portion.
Compared with prior art the invention have the benefit that fuel feed hole and steam vent are arranged at
Between first oil cylinder and the second oil cylinder, fuel feed hole is by oil inlet pipe and the first oil cylinder and the second oil cylinder
Being connected, steam vent is connected by exhaustor and the first oil cylinder and the second oil cylinder, steam vent relative
The height of the pump housing is more than the fuel feed hole height relative to the pump housing；So, brake fluid can synchronize to enter
First oil cylinder and second so that brake net synchronization capability is stable, and due to fuel feed hole and steam vent
It is set together, is convenient to process and mount, cost-effective.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of brake block in the present invention
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is made the most in detail
Describe.Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
As it is shown in figure 1, pump under the brake of the present invention, including the pump housing 1, oil cylinder 2 and brake block
5, oil cylinder includes the first oil cylinder and the second oil cylinder, and the pump housing is provided with fuel feed hole 3 and steam vent
4, fuel feed hole and steam vent are arranged between the first oil cylinder and the second oil cylinder, and fuel feed hole passes through
Oil inlet pipe and the first oil cylinder and the second oil cylinder are connected, steam vent by exhaustor and the first oil cylinder and
Second oil cylinder is connected, and the height of the relative pump housing of steam vent is more than the fuel feed hole height relative to the pump housing
Degree；So, brake fluid can synchronize to enter the first oil cylinder and second so that brake net synchronization capability
Stable, and owing to fuel feed hole and steam vent are set together, are convenient to process and mount, save into
This.
Pump under the brake of the present invention, steam vent is additionally provided with vent cap, and vent cap is installed
On steam vent, one end of vent cap is connected with the outside of steam vent by connecting band；Actual
In using, vent cap is usually the vent cap of rubber material.
Pump under the brake of the present invention, brake block includes first brake sheet and the second brake block, first
Oil cylinder and the second oil cylinder are connected with first brake sheet and the second brake block hydraulic drive respectively, and first
The side of brake block and the second brake block relative wheel is provided with friction plate, and friction plate includes stopping
Car portion 6 and guide part 7, guide part is positioned at the folder of the both sides in brake portion, guide part and friction part
Angle is more than 120 ° and less than 150 °.；So, the friction plate one end on brake block is provided with
The prerotation vane of 30～60 degree of chamferings, thus slow down the power of the changing trains or buses resistance to friction plate, prevent from rubbing
Pad comes off so that product firm and durable.
Pump under the brake of the present invention, guide part is 135 ° with the angle in brake portion；45 degree of chamferings
