Close and be arranged on first support (6), when pedal assembly (7) are into deep step on, disability switch is triggered, motor (14) enter from
By state.
In detail, in electrically-controlled component motor (14) receive shallowly step on a signal after start turning, drive shaft coupling (13) fortune
Dynamic, shaft coupling (13) drives braking shaft (5) movement, and follow-up work mode is identical as mechanical braking mode, passes through cam
(1), brake main pump (3) realizes braking function.
Electrically-controlled component includes automatically controlled clamp in second embodiment provided by the invention, and control card cramp joint receives pedal assembly
(7) start brake-by-wire mode after shallowly stepping on a signal.Automatically controlled clamp are arranged at front and back wheel, when receive shallowly step on signal after,
Automatically controlled clamp generate brake force.
Electrically-controlled component includes hub motor (14) in third embodiment provided by the invention, which receives
Start brake-by-wire mode after shallowly stepping on a signal to the pedal assembly (7).Hub motor (14) controls the operation of wheel, works as wheel
After hub motor (14) receives brake signal, hub motor (14) generates braking force control vehicle deceleration or stopping.
Specifically, integrated form braking system includes third bracket (4), and brake main pump (3) is fixed on the third bracket (4)
On.In order to which brake main pump (3) rationally puts setting third bracket (4) with stable, third bracket (4) is fixed on vehicle frame.
It is provided in second support (2) in the present invention, second support (2) is preferably u-bracket.The setting of u-bracket, it is convenient
Braking shaft (5) passes through the bracket and plays fixed function to it.
In order to facilitate the installation of, it is preferable that at least one face of u-bracket opens up non-closed pore.Brake shaft (5) and the
Two brackets (2) are fixedly connected, if braking shaft (5) and second support (2) are welded, then circle cannot be opened up in u-bracket
Through-hole, otherwise the braking shaft (5) with second support (2) can not be mounted on second support (2) by through-hole.It at this moment can be
Non- closed pore is opened up in u-bracket realizes the installation with second support (2) braking shaft (5).As shown in the figure have one it is non-close
Closed pore.
Because of the presence of non-closed pore, integrated form braking system further includes the 4th bracket (9), and the 4th bracket (9) is mounted on
The u-bracket opens up non-tight nose end, and the 4th bracket (9) passes through braking shaft (5).4th bracket (9) is mounted on second
On frame (2), the 4th bracket (9) plays a supportive role to braking shaft (5) and facilitates the installation of braking shaft (5).
The second, four brackets are usually to be made of metal material with braking shaft (5), preferably increase T-type axis in assembling process
It covers (12), is contacted on the inside of T-type axle sleeve (12) with braking shaft (5), T-type axle sleeve (12) outside and second support (2) or the 4th
Frame (9) contact.T-type axle sleeve (12) is made of rubber, nylon elastomeric material, is provided with metal when being conducive to avoid vehicle driving
Collision generates noise between metal, is also conducive to the reliability for improving vehicle.
In addition to T-type axle sleeve (12), integrated form braking system may also include cartridge sleeve (11) and axis with plum blossom retaining ring (10)；
Cartridge sleeve (11) is sleeved on T-type axle sleeve (12) and embedded between T-type axle sleeve (12) T-type side and second support (2)；Axis uses plum
Flower retaining ring (10) is sleeved in braking shaft (5), and axis is contacted with plum blossom retaining ring (10) with T-type axle sleeve (12) T shape side.It is arranged in this way
Purpose is to keep T-type axle sleeve (12) fixed.
Specifically, T-type axle sleeve (12) and cartridge sleeve (11) material are nylon or rubber.T-type axle sleeve (12) and cylindrical shaft
(11) setting is covered between bracket and braking shaft (5), and its material is nylon or rubber, play reduces during rotation
The effect of noise between contact.
In addition, the present invention provides a kind of method using integrated form braking system, for above-mentioned integrated form braking system,
It uses the method for integrated form braking system are as follows: under normal circumstances, position is shallowly stepped on using pedal assembly (7) and realizes line traffic control dynamic model
Formula；When brake-by-wire failure, steps on position deeply using pedal assembly (7) and realize mechanical braking mode.
Under this kind of mode, under normal circumstances, i.e., brake-by-wire under normal circumstances, is used only brake-by-wire and realizes that braking is dynamic
Make, when only On-line Control moves failure, mechanical braking is just activated, and passes through the purpose that deep pedal realizes braking.
Integrated form braking system should also include brake system control module, which can be separately provided, can also
To be integrated in other control modules, which inputs information, induction disability switching signal, and controls motor
(14), electronic clamp, hub motor are made whether to need to carry out braking maneuver.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
