Dynamic device is of great significance to the development for pushing China's electric car and brake-by-wire technology.
To realize that biggish output brake force, existing automobile electromechanical brake design are often filled using The gear deceleration
Set the purpose to realize deceleration force amplifier.But since the installation space of brake is limited, need to make full use of horizontal and vertical sky
Between, or more efficient force-increasing mechanism is used, to realize more compact exquisite brake executing agency.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of automotive electronics wedge brake, and driving system may be implemented
It is dynamic, and there is self-energizing.
The technical solution of the utility model are as follows:
The automotive electronics wedge brake includes braking clamp body 1, and upside friction plate 2 is fixedly connected with braking clamp body 1, under
Side friction plate 3 is fixedly connected with upper voussoir 4, and upside friction plate 2 and downside friction plate 3 are separately positioned on the two sides of brake disc 8；Under
Voussoir 5 is fixedly mounted on braking clamp body 1, and rectangular channel 5A is provided on lower wedge block 5, and motor 6 is fixedly mounted on lower wedge block 5,
The output shaft of motor 6 is connect with gear 9, and the lower end of rack gear 7 and the rectangular channel 5A of lower wedge block 5 cooperate, and rack gear 7 can be in rectangular channel
Sliding in 5A, gear 9 and rack gear 7 are intermeshed；The centre of upper voussoir 4 is provided with mounting base 4B, and the upper end of rack gear 7 passes through bolt
10, nut 11 is connect with the mounting base 4B on upper voussoir 4, and the lower end of upper voussoir 4 is provided with flange 4A, and roller 12 and flange 4A are cut with scissors
Chain link, and the contact of incline plane of roller 12 and lower wedge block 5 are equipped with extension spring 13 between upper voussoir 4 and lower wedge block 5.
Working principle: when braking, motor 6 drives gear 9 to rotate, and 9 drive rack 7 of gear is slided along rectangular channel 5A, in turn
Voussoir 4 and downside friction plate 3 generate frictional force, realize braking close to brake disc 8 in promotion；When releasing braking, motor 6 is inverted,
Rack gear 7 moves back, and voussoir 4 moves back in drive, under the action of extension spring 13, the return speed of voussoir 4 in quickening, and then accelerate
Release braking.
What the utility model can achieve has the technical effect that
The utility model structure is simple, deft design, by brake disc, downside friction plate, upper voussoir, roller, lower wedge block group
At wedge structure have self-energizing；When braking, after downside friction plate and brake disc, in the speed band of brake disc
Under dynamic, downside friction plate and upper voussoir can be made the more to press the more tight to brake disc, realize self energizing effort function, thus electric when reducing braking
The driving moment of machine, energy saving.
