Abstract
The utility model discloses a vehicular ABS (Anti-lock Brake System) wheel speed sensor which is characterized by comprising a shell, a pole shaft, an induction coil, a coil rack and a permanent magnet, wherein the pole shaft, the induction coil, the coil rack and the permanent magnet are arranged in the shell; the pole shaft is sleeved in the inner hole of the coil rack and is provided with a head part used for sensing the position change of an automobile hub tooth socket; the tail part of the pole shaft is adhered to the permanent magnet; and the induction coil is arranged on the coil rack. The vehicular ABS (Anti-lock Brake System) wheel speed sensor disclosed by the utility model has the advantages of simple structure, convenience for assembly, low cost and reliable performance.
Description
Technical field
The utility model relates to a kind of sensor, what be specifically related to is a kind of automobile-used ABS wheel speed sensors.
Background technology
Automobile-used ABS wheel speed sensors is applied to the automotive wheel anti-lock braking system; Be installed in the automotive hub place, each one of each wheel is after car moves; Teeth groove on the sensor roller hub gear ring produces ac sine waveform signal and passes to controller (ECU); Make controller (ECU) under emergency braking condition, learn the information that sensor provides, wheel is braked, thereby realize wheel anti-lock function.The automobile-used ABS wheel speed sensors complex structure of prior art, the mould input is more, and assembling is inconvenient, cost is higher, and particularly unstable than multiparameter in finished product assembling back appearance, antijamming capability is not strong, and performance reliability is relatively poor.
Summary of the invention
In view of the problem that present known technology exists, the technical matters that the utility model will solve be to provide a kind of simple in structure, easy to assembly, cost is low, the automobile-used ABS wheel speed sensors of dependable performance.
For solving the problems of the technologies described above, the utility model takes following technical scheme to accomplish:
Automobile-used ABS wheel speed sensors; It is characterized in that: said automobile-used ABS wheel speed sensors comprises shell and pole axis, inductive coil, coil former and the permanent magnet installed in the enclosure; Pole axis is set in the endoporus of coil former; Pole axis is provided with the head that induction automotive hub tooth slot position changes, and the afterbody of pole axis and said permanent magnet recline, and inductive coil is installed on the coil former.
The cutting magnetic line effect that the utility model utilizes teeth groove and the relative motion of sensor pole axis on the automotive hub gear ring to produce; The same ac sine waveform signal that produces, the same with the prior art output characteristics, but said structure is just combined by inductive coil, permanent magnet and pole axis three big parts simply; Simple in structure, easy to assembly, cost is low; And at the back parameter stability of finished product assembling, antijamming capability is strong, dependable performance.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is the structural representation of the utility model.
Embodiment
Accompanying drawing has been represented the technical scheme and the embodiment of the utility model, combines accompanying drawing to further describe each relevant details and principle of work thereof of embodiment below again.
With reference to accompanying drawing 1; The automobile-used ABS wheel speed sensors of this kind comprises nylon outer shell 5 and the pole axis 1, inductive coil 2, coil former 3 and the permanent magnet 4 that are installed in the nylon outer shell 5, and pole axis 1 adopts the pure iron material; Pole axis 1 fixed cover is located at the endoporus of coil former 3; Pole axis 1 is provided with the head 1a that induction automotive hub tooth slot position changes, and the afterbody of pole axis 1 and said permanent magnet 4 recline, and inductive coil 2 is installed on the coil former 3; Coil former 3 is installed at nylon outer shell 5 internal fixation, and inductive coil 2 has signal output terminal 6 and 7.
Above-mentioned automobile-used ABS wheel speed sensors is work like this: sensor is installed in the automotive hub place; Each one of each wheel, the head of sensor pole axis 1 is over against the teeth groove of wheel hub gear ring, after car moves; Teeth groove and pole axis 1 relative motion produce the cutting magnetic line effect; So inductive coil 2 produces the ac sine waveform signal the same with the prior art output characteristics, and through signal output terminal 6,7 signal is passed to controller (ECU), makes controller (ECU) can under emergency braking condition, learn the information that sensor provides; Wheel is braked, thereby realized wheel anti-lock function.
