Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1. multiturns are counted coil, 2. iron-core element, 3. bent axle target wheel, 4. housing, 5. magnet steel, 6. plug, 7. contact pin, 8. ring stiffener.
Embodiment
Below in conjunction with accompanying drawing and principle of work, the utility model is described in further detail, but is not the restriction to the utility model protection domain.
As shown in Figure 1, a kind of new automobile crankshaft position sensor, comprises housing 4, is arranged on the iron-core element 2 in housing 4 and counts coil 1 around the multiturn of iron-core element 2 outsides.Iron-core element 2 and multiturn are counted the disposable injection molding packaging of coil 1 in housing 4.Housing 4 left ends are provided with opening, and iron-core element 2 left ends are through corresponding with bent axle target wheel 3 positions after opening.Housing 4 right-hand members are provided with plug 6, and plug 6 centers are provided with contact pin 7, between iron-core element 2 and contact pin 7, are provided with magnet steel 5.The outer ring of housing 4 is provided with ring stiffener 8, and ring stiffener 8 is arranged on plug 6 end tops.Plug 6 snaps onto on housing 4 by some grooves and pit.The iron-core element that iron-core element 2 is made for permanent magnet, housing 4 is PA66+GF30 moulding.
The utility model when work, when the tooth in bent axle target wheel 3 and groove are with the different distance cutting sensor magnetic lines of force, and by sensor, cause that its magnetic resistance sensing changes, and then produce variable output pulse signal; In the waveform of output pulse signal and unit interval, the rate of change of magnetic resistance can directly reflect speed and relative and relative position upper dead center of the rotation of bent axle, and the sinusoidal wave change frequency of output signal is directly proportional to speed and the target wheel number of teeth that bent axle target wheel is rotated.
The utility model has improved product application flexibility, effectively reduces the degree-of-difficulty factor of installation, and simple and compact for structure, sturdy and durable; Main composition amount of parts is few, and assembly technology is easy; Be applicable to producing in enormous quantities, production cost is low, can meet automobile industry widespread demand.
