The object of the present invention is achieved like this: it comprises neutral sensor cluster 12 and neutral head stack 10, described neutral sensor cluster 12 is made up of sensor 1, sensor stand 2, plug 3, buckle 4, rivet 15, sensor stand 2 and sensor 1 usefulness rivet 15 riveted fixing, buckle 4 is connected plug 3 on the sensor stand 2; Described neutral head stack 10 is stifled 6 by connecting plate 5, dividing plate 7, back, magnet 8, the firm frame 9 of magnet are formed, and magnet 8 blocks up 6 by dividing plate 7, back and is fixed in the firm frame 9 of magnet, is connected with connecting plate 5 at last; Neutral head stack 10 is connected with gearbox shifting device 14, and neutral sensor cluster 12 is connected with gearbox casing 13.
The present invention also has some technical characteristicss like this:
1, described sensor 1 comprises 2 magnetic Hall transducers;
2, stifled 6, the magnet 8 of described dividing plate 7, back constitutes magnetic heads 11, and magnetic head 11 is oppositely arranged and leaves the gap with sensor 1;
3, described neutral head stack 10 is connected and fixed by socket head screw, nut and gearbox shifting device 14, and neutral sensor cluster 12 is connected and fixed with gearbox casing 13 usefulness bolts.
Beneficial effect of the present invention is:
1, has neutral gear and, can be applied in hybrid vehicle or have on the automobile of start and stop function in the shelves authentication function.
2, reach the energy-saving and emission-reduction purpose.When waiting red signal, identification neutral gear signal motor auto extinguishing.
3, utilize 2 road signals, by 2 magnetic Hall transducer controls, the one tunnel is the neutral gear signal respectively, other one the tunnel is Transmitted chains state relay control signal, two paths of signals for often open, normally closed interlocking state, the signals collecting end can carry out verification to two paths of signals, thus the failure judgement state.

(5) embodiment
The present invention is described further below in conjunction with the drawings and specific embodiments:
This example comprises neutral sensor cluster and neutral head stack.In conjunction with Fig. 1, described neutral sensor cluster is made up of sensor 1, sensor stand 2, plug 3, buckle 4, rivet 15.Sensor stand 2 and sensor 1 usefulness rivet 15 riveted fixing; Buckle 4 is connected plug 3 on the sensor stand 2.In conjunction with Fig. 2, described neutral head stack 10 is stifled 6 by connecting plate 5, dividing plate 7, back, magnet 8, the firm frame 9 of magnet are formed.Magnet is fixed in the firm frame 9 of magnet by dividing plate 7, back stifled 6, is connected with connecting plate 5 at last.
In conjunction with Fig. 3, neutral head stack 10 is connected and fixed by socket head screw, nut and gearbox shifting device 14, neutral sensor cluster 12 is connected and fixed with gearbox casing 13 usefulness bolts, and magnetic head 11 comprises stifled 6, the magnet 8 of dividing plate 7, back, and keeps magnetic head 11 and sensor 1 to leave certain interval.In selector when work, drive neutral head stack 10 and rotate, and magnetic head 11 produces relative movement with sensor 1, and sensor 1 transfers out signal by plug 3.In the gear shift angular range of pivot angle in the neutral gear signal definition of head stack, the magnetic Hall element magnetic flux in the sensor 1 is saturated, neutral gear signal output high level (EMS draws on the inside), and Transmitted chains state relay control signal is a low level; When the pivot angle of the head stack gear shift angular range greater than the neutral gear signal definition, the magnetic Hall element magnetic flux in the sensor 1 is lower than the magnetic saturation value, neutral gear signal output low level, and Transmitted chains state relay control signal is an open-circuit condition.This two paths of signals sends EMS to and is used for the control of automobile start and stop function.
In conjunction with Fig. 6-Fig. 7, the principle process of present embodiment is:
1, have neutral gear and in the shelves authentication function, neutral gear and gear selecting state all are considered as neutral gear, and shift shaft is to be defined as neutral gear in the scope of center ± 12 ° (error ± 2 °) with the neutral gear, is at shelves outside the neutral gear range of definition.
2, neutral switch provides 2 road signals, and by 2 magnetic Hall transducer controls, the one tunnel is the neutral gear signal respectively, other one the tunnel is Transmitted chains state relay control signal, two paths of signals for often open, normally closed interlocking state, the signals collecting end can carry out verification to two paths of signals, thus the failure judgement state.
1. under the shelves state: neutral gear signal output zero-level (normally closed attitude), Transmitted chains state relay control signal open circuit (normal ON state);
2. under the neutral state: neutral gear signal output open circuit (normal ON state), Transmitted chains state relay control signal ground connection (normally closed attitude);
3, adopt contactless " the electronics neutral switch " of magnetic Hall to improve and use the life-span, it is convenient to install.
4, parameter request:
Operating temperature: (40～125) ℃
Security level: IP65
Operating voltage: (10～16) V
