The shaft shoulder is equipped with anti-nylon axis bowl 2 and positive nylon axis bowl 8 for limiting to bearing 3 on bearing 3, two axis bowl outer circles are set
It is equipped with screw thread, be connected with vehicle frame and is fixed.Pcb board 6 is installed on sleeve 7, is welded with Hall, monolithic on the pcb board 6
Machine and resistance etc..
Magnet ring 4 used in existing sensor structure, is a full circle, and magnetic pole 5 is obtained after 4 surface of magnet ring fixed point magnetizes
Magnetic pole point, the magnetic line of force is not strong, and validity date is short；Magnet ring is mounted on the outside of the axis both ends shaft shoulder more, is easy after installation by axis
Pressure-bearing is bad, is easy to be broken by extraneous barrier when riding；Its magnetic induction line is vertical with axis axis, and the circuit board for filling Hall can occupy
Much room in axis vertical direction；Meanwhile existing sensor can destroy the space structure layout of existing complete vehicle structure.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, provide one kind and are not readily susceptible to damage, dress
Be easy and in ride, will not pulse-losing the sensor for being installed on electrical bicycle middle shaft middle position.
A kind of sensor being installed on electrical bicycle middle shaft middle position, including axis, in described axis or so two
Side is respectively arranged with a shaft shoulder, the outside in each shaft shoulder and outer wall close to the shaft shoulder is separately installed with a bearing, and one
Sleeve covers on axis and left and right ends are fixed with the outer ring inner side end of bearing respectively, solid on the axis between two shaft shoulders
Surely it is cased with a magnet ring, 12 axis parallels are uniformly provided on the same circumferencial direction of the magnet ring in the installation of axis
Hole is inlaid with magnet steel in each mounting hole, and the magnet steel and mounting hole are interference fitted, and the magnet ring is by two
Divide docking to form an annulus, is provided with circuit board recess on the sleeve, is placed with PCB in the circuit board recess
Plate is welded with Hall on the pcb board, and the Hall is arranged close to magnet ring, effectively to receive the magnetic on magnet ring
The magnetic line of force signal of steel.
The utility model has the advantage that compared with existing utility model
1. magnet ring is hatch frame, therefore can be assemblied in the middle position of mandrel of the both ends with the shaft shoulder, will not be by when riding
To damage；
2. magnetic field used in is provided by magnet steel, and magnet steel used and magnet ring are separate structure, and magnetic force is more stable, protects the magnetic phase more
It is long；
3. existing space is more reasonably utilized in axis in magnet steel axis parallel, without changing existing structure, to drop
Low research and development cost；
4. axis used in is general common axis, does not need to do any i.e. mountable structure of change.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the existing sensor being installed on electrical bicycle middle shaft；
Fig. 2 is the half-section diagram for the sensor that the utility model is installed on electrical bicycle middle shaft middle position；
Fig. 3 is the decomposition texture schematic diagram for the sensor that the utility model is installed on electrical bicycle middle shaft middle position；
