Description
Technical field
The present invention relates to automobile mechanical technical fields, and in particular to a kind of electric boosted brake system.
Background technique
Brake booster is the brake power assisting device being widely used from light-duty vehicle to compact car, can be substantially divided into
Vacuum servo, hydraulic booster and air pressure assisted.
Traditional vacuum servo brake is entirely that brake power-assisted is realized at vacuum by this engine operating air-breathing row.Allusion quotation
If type feature is exactly that engine is flame-out, vacuum servo will soon fail.At this time braking ability is greatly reduced.So
It can only normally step on after automobile flameout and brake three times, just lose power-assisted stepping on later.Brake pedal can not be stepped on any more, and natural braking effect is difficult
The defects of to guarantee, while hydraulic booster is there is also oil leaking pollution, and structure is complicated.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of efficient electricity of braking
Dynamic servobrake system.
The purpose of the present invention can be achieved through the following technical solutions: a kind of electric boosted brake system, the system packet
Include the push rod connected in the middle part of foot pedal, tail end and foot pedal by shaft and the brake block connecting with push rod front end, the system
System includes the electric drive unit for pushing push rod to be moved forward and backward along its axis.Pass through the driving of electric drive unit, power-assisted
The back-and-forth motion of push rod is braked light, sensitive when realizing low speed；Braking efficiency height, swift advantage when high speed.
The electric drive unit servo motor, the worm couple engaged with servo motor shaft, the worm gear snail
Bar pair is in T shape, the worm screw of worm gear and integrated setting including top horizontal setting in worm gear bottom center, the worm gear
It is engaged with servo motor shaft, the bottom of the worm screw is equipped with gear and engages with push rod.
Power-assisted rack gear is equipped in the middle part of the push rod, the power-assisted rack gear is equipped with the tooth engaged with worm screw bottom gears.
The power-assisted rack gear is hollow structure, and both ends inner wall is equipped with internal screw thread, and is screwed onto the middle part of push rod.In
Empty power-assisted rack gear, and existing brake assist system is replaced by small-sized servo motor, worm couple, can effectively it mitigate
Vehicle weight.
The foot pedal is L-shape, and the top for being located at " L " vertical portion is rotatably connected on automobile, and the push rod
Tail end and foot pedal on be located at the intermediate connection of " L " vertical portion.
The foot pedal is located at " L " horizontal component equipped with pressure sensor, the control of the pressure sensor and automobile
Device connection processed, the servo motor are connect with controller.When people steps on foot pedal, pressure sensor senses pressure, and will letter
Number controller is passed to, when pressure reaches certain numerical value, controller judges that people wishes brake, therefore controls servo motor rotation
Turn, drives power-assisted rack gear to advance by worm couple, so that brake block be pushed to brake；After people unclamps foot pedal, pressure
The signal of pressure is passed to controller by sensor, and after pressure is less than certain numerical value, controller judges that people thinks releasing of brake,
Control servo motor rotates backward, and drives power-assisted rack retreats by worm couple, brake terminates.
Compared with prior art, the beneficial effects of the present invention are embodied in following several respects:
(1) transmission efficiency is got higher, and degree of safety improves；
(2) complete vehicle weight is alleviated, it is compact-sized, easy for installation, it lays foundation for unmanned, automatic Pilot；
(3) system noise is reduced, comfort and safety are improved；
(4) low speed brake is light, sensitive, brakes strong, high-efficient, reaction at a high speed fastly.
Detailed description of the invention
Fig. 1 is connection schematic diagram of the invention；
Fig. 2 is the structural schematic diagram of power-assisted rack gear of the present invention.
Wherein, 1 is foot pedal, and 2 be shaft, and 3 be worm couple, and 4 be servo motor, and 5 be power-assisted rack gear, and 6 be gear,
7 be push rod.
Specific embodiment
It elaborates below to the embodiment of the present invention, the present embodiment carries out under the premise of the technical scheme of the present invention
Implement, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to following implementation
Example.
Embodiment 1
A kind of electric boosted brake system, the system include being connected in the middle part of foot pedal 1, tail end and foot pedal 1 by shaft 2
Push rod 7 and the brake block that is connect with 7 front end of push rod, system include the electricity for pushing push rod 7 to be moved forward and backward along its axis
Dynamic driving unit.By the driving of electric drive unit, the back-and-forth motion of power-assisted push rod 7 is braked light, clever when realizing low speed
It is quick；Braking efficiency height, swift advantage when high speed.
Electric drive unit servo motor 4, the worm couple 3 engaged with 4 shaft of servo motor, worm couple 3 are in T
Font, the worm screw of worm gear and integrated setting including top horizontal setting in worm gear bottom center, worm gear and servo motor 4
Shaft engagement, the bottom of worm screw are equipped with gear 6 and engage with push rod 7.
Power-assisted rack gear 5 is equipped in the middle part of push rod 7, power-assisted rack gear 5 is equipped with the tooth engaged with worm screw bottom gears 6.
Power-assisted rack gear 5 is hollow structure, and both ends inner wall is equipped with internal screw thread, and is screwed onto 7 middle part of push rod.Using hollow
