Detailed description of the invention
Auxiliary brake device for automobile of the present utility model will be described below in detail on the basis of combining accompanying drawing.Car auxiliary brake of the present utility model fills
Putting and include mechanical component and two parts of Electronic Control Unit, wherein mechanical component part includes: support (1), and support (1) and automotive floor panel are solid
Connection；The pilot sleeve (2) hinged with support (1)；The electric pushrod (3) being arranged in pilot sleeve (2), electric pushrod (3) is built-in
Elongate or shorten under the effect of motor (2.4)；The brake pedal shaft (4) hinged with electric pushrod (3), brake pedal shaft (4) revolves counterclockwise
The braking of automobile can be realized after Zhuaning；Return spring (not shown), return spring can make brake pedal shaft turn clockwise thus release automobile
Braking.
Support (1) is fixed on automotive floor panel, and pilot sleeve (2) and support (1) are hinged, and electric pushrod (3) can be in pilot sleeve (2)
Inside sliding axially, during braking, electric pushrod (3) extends at pilot sleeve (2), drives brake pedal shaft (4) to rotate counterclockwise, it is achieved vapour
The braking of car；After brake release, electric pushrod (3) is retracted, brake pedal shaft (4) dextrorotation under the effect of return spring (not shown)
Turn, release automobile brake.Time not braking, electric pushrod (3) is in the state of retraction, now pilot sleeve (2) and electric pushrod (3) it
Between can slide axially, brake pedal shaft (4) can be the most flexible under the effect of driver pedal, and therefore, this set complemental brake system is not
Original brakes can be produced any impact.
The Electronic Control Unit part of the complemental brake system of this utility model includes: input interface (2.1), CAN driver (2.2), single-chip microcomputer
