Abstract
A sensing pulse ring structure for wheel speed consists of a brake drum, a brake bottom plate, a pulse gear ring and a sensor and is characterized in that the pulse gear ring device is arranged at the opening direction to the brim of the brake drum where the pulse ring gear can be processed, or the precast pulse gear ring can be fixed on the brake drum in an installation way; the sensor is positioned on the brake bottom plate by a support to align the pulse gear ring. Compared with the prior art, the utility model has the advantages that: 1. the installation site of the sensor can not be influenced by the inner structure of the brake and can be operated on nearly all the models of cars; 2. the sensor is positioned at the outer side of a brake, thereby being not influenced by the high temperature produced by the braking mechanism; 3. when the pulse gear ring is installed, a wheel hub, the brake bottom plate and other key devices do not need to be processed, therefore, no original components are damaged; 4. the pulse gear ring has a relatively larger diameter, the signal intensity can be improved according to the enhancement of the sensor speed; 5. the brake drum does not need to be disassembled when the sensor is installed, adjusted and replaced; the operation can be carried out directly.
Description
Technical field
The utility model relates to a kind of pick-up unit of wheel velocity.
Background technology
The kinetic control system of vehicle need obtain wheel velocity accurately.Main wheel velocity signal obtain manner is a magneto-electric at present, promptly by the rotation of pulse ring, makes the speed pickup that is fixed on the vehicle bridge produce the curtage of the varying strength that changes with wheel velocity, thereby obtains wheel velocity signal.Existing magneto-electric sensing mode as shown in Figure 1, its structure is that pulse ring 6 edges are enclosed within on the vehicle hub 7, speed pickup 1 is fixed on car brakeing base plate 3 by support 2, the motion of wheel hub 7 makes also movement therewith of pulse ring 6, the motor message of pulse ring 6 is detected by speed pickup 1, pass through the receiving circuit collection and treatment again, thereby obtain faster rotating wheel.The above-mentioned this mode of obtaining wheel velocity has following weak point:
1. sensor is installed difficulty, need process wheel hub or steering knuckle during sensor installation, and forming behind the mating surface again, edge overlaps pulse ring;
2. carrying out pulse ring and sensor when installing, can carry out the processing that interest is removed material to wheel hub and back-plate usually, this trade union that adds causes to a certain degree destruction to wheel hub and back-plate;
3. replacing sensor and maintenance are inconvenient, because brake drum surrounds the back-plate wheel hub, in the time of or changing the sensor maintenance, wheel and arrestment mechanism, gear train will be wiped and are unloaded usually;
4. need certain clearance between sensor and the pulse ring, but enclose, inconvenience is adjusted in the gap because of sensor is braked bulge;
5. the pulse ring diameter that is installed on the wheel hub is less, and the relative velocity of itself and sensor is also less, corresponding output signal intensity a little less than;
6. because vehicle produces a large amount of heats in braking procedure, brake drum is inner because heat radiation is bad, and the rising meeting of temperature causes bad influence to sensor;
7. the vehicle of some brake drum inner structure compactness, the space that pulse ring and sensor are not installed.
Summary of the invention
The purpose of this utility model is to propose a kind of wheel velocity sensing pulse ring structure, adopt this frame mode can so that the installation, maintenance of sensor, replacing and gap adjust more convenient, the working environment of sensor improve and adaptability wider.
For achieving the above object, the utility model adopts following technical scheme:
A kind of wheel velocity sensing pulse ring structure, form by brake drum, back-plate, pulse ring gear and sensor, it is characterized in that: the pulse ring gear is arranged at the opening direction of brake drum by edge, this pulse ring gear can process by edge by the opening direction at brake drum, perhaps prefabricated pulse ring gear is fixed on the brake drum by the mode of installing; With support sensor is installed on the back-plate, during installation with sensor alignment pulse ring gear.
With existing technology contrast, the utlity model has following advantage:
1. the installation site of sensor is not influenced by the detent inner structure, almost can carry out on all vehicles;
2. sensor is positioned at the detent outside, and sensor will not be subjected to the influence that arrestment mechanism produces high temperature;
3. installing when forming the pulse ring gear does not need vitals such as wheel hub, back-plate are processed, and does not damage original parts;
4. the pulse ring gear has bigger diameter, and with respect to the movement velocity increase of sensor, signal intensity will increase;
5. the installation of sensor, debugging and replacing do not need dismounting braking clappers, can directly operate.
With accompanying drawing the utility model is further described below:
