Problems solved by technology
[0005] Usually the polar axis of the magnetic induction sensor head is perpendicular to the tooth end on the gear ring, and there is a gap of 1mm between the polar axis and the tooth end, and the size of the gap affects the signal amplitude of the sensor, thereby affecting whether the sensor outputs a correct signal, and then Affect the effect of precise braking of the vehicle. It is inevitable to encounter bumps during driving, which makes the offset between the tooth end on the gear ring and the pole axis of the magnetic induction sensor head, that is, the size of the gap changes, which in turn affects the sensor. signal amplitude, which has a certain impact on vehicle braking

Embodiment
[0040] An ABS car sensor of this embodiment, refer to Figure 1-10 : Including the axle tube 1, the axle tube 1 is fixed with the wheel axle of the automobile; the outer circumference of the axle tube 1 is fixed with a ring seat 4, and the ABS gear ring 2 and the fixing ring 5 are respectively detachable and installed on both sides of the ring do 4;
[0041] Specifically, refer to Figure 2-7, the ring seat 4 is provided with several groups of first fixing holes 14 at equal angles (this technical solution preferably has 10 groups of first fixing holes 14). One side is respectively provided with the same number of screw rods 17 as the first fixing holes 14 and one-to-one correspondence. At the same time, the fixing ring 5 is composed of two sets of semi-circular rings, and the side of the fixing ring 5 facing the ring seat 4 and the side facing away from the ring seat 4 A second fixing hole 15 and a third fixing hole 16 corresponding to the first fixing hole 14 in one-to-one c...

The invention relates to the technical field of sensors, in particular to an ABS automotive sensor, which includes a shaft tube, an ABS ring gear and an ABS wheel speed sensor. The other side is detachably installed with the ABS ring gear, and a dust cover is rotatably connected between the outer side of the ring base and the outer side of the fixed ring, and the front side of the dust cover is provided with a fixed tube parallel to the axis of the shaft tube; Disassemble the ABS ring gear, ABS wheel speed sensor and the attached parts, so as to facilitate maintenance or replacement, through the rotating connection between the dust cover and the ring seat, and the fixing of the ABS wheel speed sensor and the dust cover, and through the action of the elastic parts , so that the vibration of the ring seat synchronously drives the ABS wheel speed sensor to vibrate, so that the position of the ABS wheel speed sensor and the ABS ring gear does not change, that is, the pole axis of the ABS wheel speed sensor and the tooth end of the ABS ring gear are effectively avoided. Effectively avoid certain errors.
Description
technical field [0001] The invention relates to the technical field of sensors, in particular to an ABS automobile sensor. Background technique [0002] An ABS sensor is a sensor used to measure the rotational speed of a car's wheels. For modern cars, wheel speed information is essential. Vehicle Dynamic Control System (VDC), Automotive Electronic Stability Program (ESP), Anti-lock Brake System (ABS), and automatic transmission control systems all require wheel speed. speed information. Therefore, the ABS sensor is one of the most critical sensors in modern cars. [0003] Usually, ABS sensors mainly include: magnetoelectric wheel speed sensor and Hall wheel speed sensor. The magnetoelectric wheel speed sensor generally includes a magnetic induction sensor head and a ring gear. The magnetic induction sensor head is composed of a permanent magnet, a pole shaft and an induction coil. The magnetic induction sensor head is a static part, while the ring gear is a moving part. ...
