Abstract
The utility model discloses a magnetic sensitive sensing wheel which comprises a base, a nylon connecting ring and a magnetic ring, wherein the base is fixedly connected into a through hole of the nylon connecting ring; a clamping ring is arranged at one end of the nylon connecting ring; a clamping groove is arranged at the position of the magnetic ring, which is corresponding to the clamping ring; and the magnetic ring is fixedly connected to the nylon connecting ring through matching between the clamping groove and the clamping ring. The magnetic sensitive sensing wheel has the advantages of high strength and low weight.
Description
Technical field
The utility model relates to electric motor of automobile accessory field, is specifically related to the sensing wheel on a kind of electric motor of automobile.
Background technology
Sensing wheel and electromagnetic sensor combine in automobile, are called induction crankshaft position sensor.The effect of induction crankshaft position sensor is to provide the rotating speed of engine and the angular signal of bent axle to automotive control system.Engine speed is that automotive control system is judged engine operation condition, selects the Main Basis of control program and definite control initial parameter, also is that automotive control system calculates necessary basic parameter to a working cycle air amount of engine amount.
Sensing wheel is as core parts in the induction crankshaft position sensor, on the structure, it is a discoid part, be evenly distributed with magnetic material in circumferential edge, accept the magnetic material electric signal by the inductance sensor device, and change into rotating speed and position signalling, offer automotive control system.And the sensing wheel dynamic test system is the precision that detects the sensing wheel element, and provide complete dynamic data analysis, it is the electromechanical integrated product that integrates the technology such as computing machine, automatically detection, mechanical drive, measuring accuracy and automaticity are high, are the automated test devices that Prospect in Modern Auto Manufacture Industry is badly in need of.
Traditional sensing wheel adopts the machine-shaping of magnetic material one, and the sensing wheel cost that this technique obtains is higher and physical strength is lower, therefore is necessary existing sensing wheel is made improvements.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of with low cost, sensing wheel that physical strength is high.
The utility model is achieved by the following technical solution: a kind of magnetosensitive sensing wheel, comprise pedestal, nylon abutment ring and magnet ring, described pedestal is fixedly connected in the through hole of nylon abutment ring, be provided with snap ring on one end of described nylon abutment ring, described magnet ring is provided with draw-in groove corresponding to the position of snap ring, and magnet ring is connected on the nylon abutment ring by being fixed of draw-in groove and snap ring.
The utility model compared with prior art, have following beneficial effect: production cost is low, quality is little and physical strength is high.
