Cross mutual intermediate duct to realize, the technological deficiency of the technical scheme is：Overall volume is big, weight is big, structure is not compact, response
Time is slow, while being also not easy to main engine plants' design system installation site when entrucking is laid out.It would therefore be highly desirable to improve.It is described antilock
Dead brakes ABS, full name is Anti-lock Brake System, be it is a kind of have prevent wheel lock up, shorten automobile system
Dynamic distance, reduction tire wear, the vehicle safety control system for the advantages of preventing Vehicle Driving Wandering, whipping, it is based on conventional brake
System works.In the case where wheel is close to locking, corresponding wheel brake pressure will be released and require or measuring car
Wheel keeps constant during accelerating again, and brake pressure is stepped up after accelerating again.It is single equivalent to each wheel
" point is stopped ".The Anti-slip regulation system ASR, full name is Acceleration SlipRegulation, is Anti-slip regulation system
It is TCS.When vehicle wheel rotation, vehicle body is motionless or translational speed of automobile is less than the wheel linear velocity for rotating wheel
When, just there is relative slip between wheel tyre surface and ground, this slip referred to as " is trackslipped ", to be different from wheel during automobile brake
Locking and the wheel " dragging cunning " produced.Trackslipping for driving moment, equally can decline wheel and the adhesive force on ground.Vehicle skidproof
It is when wheel trackslips, by imposing brake force to the car that trackslips or controlling the power output of engine to turn electronic control system
To suppress trackslipping for wheel, to avoid the decline of vehicle traction and riding stability.
Patent No. ZL201710088978.1 Chinese invention patent discloses a kind of commercial car brakes compact
Back axle brake module, belongs to vehicle brake technology field.This brakes compact back axle brake module include upper valve body and
