Description
Technical field
The present invention relates to pure electric automobile brake fluid system, particularly to a kind of for pure electric automobile hydraulic braking
Vacuum boost system.
Background technology
The most existing pure electric automobile brake fluid system use hydraulic vacuum assist type, this structure mainly by:
Electric vacuum pump, controller for vacuum pump, vacuum tank, vacuum tube, vacuum booster form.The power-assisted energy is carried by electric vacuum pump
Confession, vacuum controller controls the start and stop of vacuum pump by vacuum values set in advance；Vacuum-energy can be produced during vacuum pump work；Produce
Raw vacuum-energy is stored in vacuum tank；Vacuum tube connects vacuum pump, vacuum tank, vacuum booster, in order to transmit vacuum-energy；Very
Empty booster consumes vacuum-energy and provides power-assisted for braking.As this system vacuum controller lost efficacy, driver cannot predict in time
Braking system faults, in case of emergency cannot brake.
It addition, current competing product vehicle brake vacuum system all configures single controller for vacuum pump+little volume vacuum tank.Client
Use road conditions more complicated, such as: the frequency that during long and steep downgrade, driver touches on the brake is higher, more large and fast to the demand of vacuum-energy,
Single controller for vacuum pump+little volume vacuum tank form control device is susceptible to fault, and vacuum space is too small, and vacuum pump can not
Feeding vacuum-energy in time, cause vacuum servo not enough, brake efficiency reduces, and causes stopping in time time serious.
Summary of the invention
The present invention seeks to: a kind of vacuum boost system for pure electric automobile hydraulic braking is provided, prevent from running over
Cheng Zhong, when vacuum controller breaks down, driver cannot obtain vehicle trouble in time, causes vehicle accident.
The technical scheme is that
A kind of vacuum boost system for pure electric automobile hydraulic braking, described vacuum boost system includes vacuum tank, vacuum
Pump and vacuum booster, described vacuum pump and vacuum booster are connected to vacuum tank by vacuum tube respectively, on described vacuum tank
It is provided with two vacuum controllers in parallel, the vacuum values of described vacuum controller detection vacuum tank, controls vacuum pump work and produce
Raw vacuum-energy, is also associated with voice vacuum warning system simultaneously on vacuum controller, when vacuum values is less than setting value, control language
Sound vacuum warning system sends voice alarm.
Preferably, the vacuum controller that said two is in parallel can form complete loops with miscellaneous part respectively.
Preferably, when described vacuum values is less than setting value, controls voice vacuum warning system and send voice alarm.
Preferably, described vacuum controller is also associated with instrument warning system, when vacuum values is less than setting value, controls
Instrument warning system sends display lamp warning.
Preferably, the volume of described vacuum tank is a certain liter.
The invention have the advantage that
Vacuum boost system for pure electric automobile hydraulic braking provided by the present invention, changes existing vacuum boost system
Enter for dual controller+big volume vacuum tank form, two controller parallel connections, and all can control vacuum pump start and stop, can independent be
Unite other assembly constitute complete loops, it is ensured that two vacuum controller at least a normal job, i.e. vacuum during complex road condition
System can normally work, the vacuum booster demand to vacuum-energy when a certain liter capacity vacuum tank can guarantee that brake continuously.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings and embodiment the invention will be further described:
Fig. 1 is the structure principle chart of vacuum boost system of the present invention；
Wherein: 1-vacuum tank, 2-vacuum pump, 3-vacuum booster, 4-vacuum tube, 5-vacuum controller.
Detailed description of the invention
Embodiment:
As it is shown in figure 1, the disclosed vacuum boost system for pure electric automobile hydraulic braking, described vacuum servo
System includes vacuum tank 1, vacuum pump 2 and vacuum booster 3, and described vacuum pump 2 and vacuum booster 3 are respectively by vacuum tube 4
Being connected to vacuum tank 1, relatively low because of vacuum system vacuum values during vehicle launch, electric vacuum pump is started working, the vacuum-energy of generation
Being stored in vacuum tank, when braking generation demand, vacuum tank provides vacuum-energy by vacuum tube to vacuum booster, reaches to help
Power effect.
Being provided with two vacuum controllers 5 in parallel on described vacuum tank 1, described vacuum controller 5 detects vacuum tank
Vacuum values, sends vacuum pump control signal to vacuum pump, controls vacuum pump work and produces vacuum-energy, simultaneously vacuum controller on also
Connecting and have voice vacuum warning system and instrument warning system, when vacuum values is less than setting value, controlling the warning of voice vacuum is
System sends voice alarm, instrument warning system sends display lamp warning.
Because comprising the Yunnan-Guizhou Plateau in view of pure electric coach sales region, road conditions ramp is many, requires the highest to brakes,
There is hidden danger in the single vacuum controller+little volume vacuum tank of conventional vacuum system configuration: 1, conventional vacuum system configuration only 1 is true
Empty pump controller, when breaking down, vacuum pump cannot work and cause vacuum not enough, and brake fade easily causes security incident；2、
The vacuum-energy that little volume vacuum tank stores is limited, and when vacuum deficiency, controller control vacuum pump is started working, but vacuum pump carries
Speed for vacuum is much smaller than vacuum booster wear rate, causes vacuum servo not enough, and brake efficiency reduces, and reduction is driven easypro
Adaptive, causes security incident time serious.For this kind of deficiency, this invention configuration dual controller+big volume vacuum tank, use 2
Controller for vacuum pump, sets up double-loop control system, and every controller can help with vacuum pump, vacuum tank, vacuum tube, vacuum
Power device constitutes independent loop, original for vacuum tank volume is promoted to large volume, has both ensured when single controller breaks down another
One controller can normally work, demand to vacuum-energy when meeting again long and steep downgrade.
Above-described embodiment, only for technology design and the feature of the explanation present invention, its object is to allow person skilled in the art
Will appreciate that present disclosure and implement according to this, can not limit the scope of the invention with this.All according to master of the present invention
Want the modification that the spirit of technical scheme is done, all should contain within protection scope of the present invention.
