Description
Technical field
The invention belongs to anti-block braking system of car (hereinafter referred to as " ABS ") field, and in particular to a kind of ABS wheels side coordinates
System.
Background technology
Existing automobile nearly all standard configuration ABS system, for preventing wheel lock up, during operator brake, produces
Severity of braking it is excessive when, namely vehicle rim brake produce brake force be more than transferable attachment between tire and road surface
During power, wheel will be changed into simple sliding state from pure rolling state, namely locking operating mode occur, and the wheel lock up in braking procedure
Operating mode belongs to dangerous working condition, and vehicle can be caused to be in whipping state or lose directional stability, and now ABS is functioned to.
When vehicle severity of braking is excessive, the central electronic control device of ABS system is recognized by the wheel speed signal that wheel speed sensors are obtained
Go out the locking tendency of one or more wheels and thus calculate the pressure control device acted on corresponding brake chamber
The control situation of (hereinafter referred to as " ABS magnetic valves ").According to the adhesion condition between wheel condition, tire and track, by means of
ABS magnetic valves come realize brake air chamber pressure decline, keep or set up so that control vehicle rim brake produce system
The size of power, while preferable severity of braking is obtained, regulation wheel condition is allowed in interval to optimal slip rate.
ABS wheel side coupled systems are one of core components of ABS system, for giving ABS system central electronic control device
Sensitive, effective, stable, reliable wheel speed signal and wheel condition signal are provided, its performance directly affects the property of ABS system
Energy.ABS wheel side coupled systems include ABS gear rings, matched wheel speed sensors and other related accessories composition.At present for
Non- wheel edge deceleration driving axle vehicle, ABS wheel side coupled systems are arranged near wheel hub mostly, and ABS gear rings are fixed on wheel hub, tooth

Further, the ABS gear rings circumference tooth forms radial direction gap and coordinates with wheel speed sensors, and fit clearance is
0.1~0.7mm.
Further, the ABS gear rings are directly integrated with wheel side input bead, and in wheel side input bead connection
Process rectangle or involute spline tooth in the circumferential end faces of flange, transverse tooth thickness 8mm to 15mm scopes, number of teeth amount is from 30 to 120 models
In enclosing, circumference uniform distribution.
Further, there is a through hole on the wheel speed sensors clamping device 6, while in hub reduction gear assembly knuckle
A through hole and the bolt hole being engaged with the through hole on wheel speed sensors clamping device are processed on shell, wheel speed sensors are clamped
Device is installed in through hole by bolt, and wheel speed sensors are fixed by gripping apparatus grips.
Further, the ABS wheels side coupled system protective stent 5 is toroidal, is symmetrically welded reinforcement at two,
Two installation through-holes are processed on reinforcement, knuckle shell is provided with the bolt hole being engaged with the through hole on protective stent, led to
Bolt is crossed to be fixed on hub reduction gear assembly knuckle shell, the circumferential end faces of protective stent 5 processing two be arranged symmetrically half
Circular hole, left and right wheels side is general, and wheel speed sensors form gap and coordinate by this hole with ABS gear rings circumference tooth.
Compared with prior art, advantages of the present invention is as follows：
ABS wheels side coupled system of the invention is arranged in outside hub reduction gear assembly shell, and system axial, radially loading are matched somebody with somebody
And adjustment space is abundant, gear ring structure shape can be designed rationally；Gear ring is located in atmospheric environment, without fluid parcel, is not interfered with
Output wheel speed signal quality；Gear ring directly with wheel side input bead integrate, reduce systematic part quantity, reduce processing and
Assembly process, drop weight cost declining；Wheel speed sensors coordinate after clamping device is fixed with the chucking power for setting with the gear ring flank of tooth,
Shift wheel speed sensors onto extreme position, sensor end face and gear ring end contact in advance, then rotated in wheel side input bead
During, wheel speed sensors to be pushed open, wheel speed sensors end face forms optimal fit clearance with gear ring end face；Left and right wheel ABS
