Abstract
The utility model discloses a system, particularly a pulse ring for a vehicle wheel speed sensor. The utility model is directly processed by the end face in the opening direction of a brake drum, or the end face is added with materials to form pulse teeth 10, wherein, a vehicle wheel speed sensor 1 is installed on a brake bottom plate 3 and is contacted with the pulse teeth 10, and consequently, the vehicle wheel speed is accurately measured.
Description
The utility model belongs to vehicle wheel speed sensors pulse ring, particularly a kind ofly utilizes the end face processing of braking hub opening direction or at the end face additional materials, thereby forms the vehicle wheel speed sensors pulse ring of pulse teeth.
Modern vehicle is more and more used the motion of electronic installation control vehicle, such as anti-blocking brake system of automobile (ABS).The vehicle movement control system need be obtained wheel wheel speed signal accurately, it is rotation by the extra-pulse ring that existing the most frequently used wheel wheel speed signal obtains, the vehicle wheel speed sensors that is fixed on the vehicle bridge is produced with wheel velocity change electric pulse or the voltage that produces varying strength, thereby obtain the wheel wheel speed.At present, in the automotive brake of nearly all drum-type structure, additional pulse ring all is that edge is enclosed within on the vehicle hub, and the vehicle wheel speed sensors then is fixed on the car brakeing base plate, see accompanying drawing 1 (the 1st, the vehicle wheel speed sensors; The 2nd, sensor stand; The 3rd, back-plate; The 4th, the braking hub; The 5th, detent; The 6th, the extra-pulse ring; The 7th, swivel bearing; The 8th, oil sealing; The 9th, steering knuckle or semiaxis).The shortcoming of this mounting means is:
The vehicle wheel speed sensors is installed difficulty.Carrying out when the vehicle wheel speed sensors installs, need be to the wheel hub of vehicle, semiaxis or steering knuckle are processed, forms a mating surface after, the extra-pulse ring of edge cover through processing again;
Maintenance of vehicle wheel speed sensors and replacing are inconvenient.Because brake drum surrounds back-plate, wheel hub, carries out the maintenance and the replacing of vehicle wheel speed sensors if desired, needs removing vehicle tyres usually and dismantles arrestment mechanism, gear train, need expend a large amount of man-hours and manpower;
Need certain clearance between vehicle wheel speed sensors and the extra-pulse ring.Because extra-pulse ring edge is enclosed within on the hub for vehicle wheel, is braked hub and surrounds, make the gap adjustment and determine inconvenient;
Existing vehicle wheel speed sensors output signal strength is influenced by sensor and the pulse ring gap and the relative velocity that add.The common extra-pulse ring that is installed on the vehicle hub is less owing to diameter, and is also less with the relative velocity of vehicle wheel speed sensors, and corresponding sensor output signal intensity is also less;
Because vehicle produces a large amount of heats in the process of braking, the braking hub is inner because heat radiation is bad, and temperature is the highest may be above 400 degrees centigrade.Bad working environment has improved the requirement to the vehicle wheel speed sensors like this, and make cost increase: the reliability to the vehicle wheel speed sensors also has very big influence simultaneously;
In the process of carrying out extra-pulse ring edge cover and the installation of vehicle wheel speed sensors, usually can be to the wheel hub of vehicle, steering knuckle, semiaxis are removed the processing of material, and this intensity that adds trade union's destruction parts forms potential safety hazard to vehicle;
Some vehicle is because structure is special, and braking hub inner space is narrow and small, and additional pulse ring and vehicle wheel speed sensors can't be installed in the space that extra-pulse ring and vehicle wheel speed sensors are not installed at all, can't measure the speed of wheel.
The purpose of this utility model is to utilize the end face processing of braking hub opening direction or at the end face additional materials at the design of the shortcoming of above-mentioned existence is a kind of, thereby forms the vehicle wheel speed sensors pulse ring of pulse teeth.
The purpose of this utility model is by following scheme implementation: utilize the end face processing of braking hub opening direction or at the end face additional materials, thereby form pulse teeth; Thereby vehicle wheel speed sensors and sensor stand are installed on back-plate and are processed corresponding breach and obtain the wheel wheel speed signal so that pulse teeth is contacted with the vehicle wheel speed sensors.
Because adopt the utility model, the installation, maintenance of vehicle wheel speed sensors, replacing and gap adjustment will be very convenient, vehicle wheel speed sensors condition of work will be improved greatly; Simultaneously, this vehicle wheel speed sensors pulse ring can not destroyed steering knuckle, and the intensity of main stressed member such as semiaxis, wheel hub can improve signal quality and be applicable to various car wheel structures simultaneously.
Accompanying drawing 2 is structural representations of the present utility model.In conjunction with the accompanying drawings 2 and embodiment, further describe structure of the present utility model and principle of work.
Structure of the present utility model such as accompanying drawing 2:1 are the vehicle wheel speed sensors; The 2nd, sensor stand; The 3rd, back-plate; The 4th, the braking hub; The 5th, detent; The 7th, swivel bearing; The 8th, oil sealing; The 9th, semiaxis, steering knuckle; The 10th, pulse teeth on the braking hub end face.
Principle of work of the present utility model is the additional pulse ring 6 on the cancellation accompanying drawing 1, directly process or additional materials on end face at the end face of braking hub opening direction, thereby form pulse teeth 10, the vehicle wheel speed sensors is installed on back-plate 3 and pulse teeth 10 is contacted with vehicle wheel speed sensors 1.
In wheel of vehicle when rotation,, braking hub 4 rotate thereupon, pulse teeth 10 rotations of processing on the braking hub 4, thus be installed in the speed that vehicle wheel speed sensors 1 on the back-plate 3 is measured wheel exactly, reach the purpose of accurate measurement.
Owing to adopt the utility model to make the installation site of vehicle wheel speed sensors 1 transfer to detent 5 outsides from partly or entirely being positioned at detent 5 inside, the installation site of vehicle wheel speed sensors 1 will not be influenced by detent 5 inner structures will, almost can carry out on all vehicles; Because move outside vehicle wheel speed sensors 1 position, vehicle wheel speed sensors 1 will not be subjected to the influence of detent high temperature; Do not need braking hub 4, back-plate 3, steering knuckle, semiaxis 9 important spare parts such as grade are processed, and have guaranteed the intensity of part; Pulse teeth 10 increases to some extent with respect to vehicle wheel speed sensors 1 line of motion speed, and signal intensity will increase; The installation of vehicle wheel speed sensors 1, debugging and replacing no longer need to dismantle detent 5, can directly operate on it.Utilizing braking hub 4 end faces processing pulse teeth 10 is brand-new thinkings, and for traditional vehicle wheel speed sensors arrangement, it will be a revolution, can expect, in the near future, have more braking hub and will adopt such version.Such frame mode is with the application of propelling vehicle vehicle movement control system on vehicle.
