Abstract
The invention discloses a contactless neutral position sensor. The sensor comprises an inducting target block and a sensor body, wherein the inducting target block is fixed on a gear-shifting control shaft, and the sensor body is fixed on a gear-shifting control shaft fixing body which is fixed on the casing of a gear box. In the contactless neutral position sensor, the signal error problem brought by temperature, fit clearance and design tolerance is overcome; meanwhile, the sensor body and magnet are integrated and fixed inside the gear box, thereby avoiding that a signal is influenced due to dust adsorption; and the contactless neutral position sensor adapts to the gear box with different shift displacements by labeling the neutral position scope, and has good universality.
Description
Technical field
The present invention relates to the automobile variable speed case apparatus, particularly a kind of contactless neutral gear sensor.
Background technique
At present, the world energy sources crisis, vehicle increases, the greenhouse effect aggravation, corresponding requirements is all made to the vehicle fuel consume in countries in the world, simultaneously respective specified is also made in emission from vehicles.The vehicle start stop system is having major contribution aspect fuel-economizing and the minimizing discharging; One of start stop system essential elements is the neutral gear sensor; The neutral gear sensor is passed to central processing unit (CPU) with the neutral gear signal; Central processing unit (CPU) combines tach signal and engine load signal to judge whether energy surplus of motor again, and then the storage of definite generator electric energy.Develop a highi degree of accuracy, the neutral gear sensor of good reliability, most important to the proper functioning of safeguards system start stop system.And present many neutral gear sensors all are switch types, and this neutral gear sensor causes the systemic-function non-normal working owing to magnet absorption iron filings cause the signal variation easily, also can bring signal errors because of temperature, fit up gap, design tolerance simultaneously.In application facet, can not bring into play the advantage of present mixed power, oil-saving effect is not clearly; In addition, this sensor directly separately is fixed in the gearbox outside to magnetic field and sensor body, after long-term the use, owing in poor performance aspect preventing dust, sensor is lost efficacy in use for some time.
Summary of the invention
The objective of the invention is; Solve the problem that signal is provided to control unit during at the neutral gear regional location when gearbox; Solve present switch type neutral gear sensor the neutral gear signal can only be provided on one point; And overcome owing to magnet absorption iron filings cause that signal changes and cause the systemic-function non-normal working, improve VE Vehicle Economy.
For realizing above-mentioned purpose; The technological scheme that the present invention adopts is; Contactless neutral gear sensor comprises induction targets piece and sensor body, and said induction targets piece is fixed on the gear shift control axle; Said sensor body is fixed on the gear shift control axle fixed body, and gear shift control axle fixed body is fixed on the gear box casing.
Said sensor body is that the programmable hall element is housed in the housing, and programmable hall element one side is pasted with magnet, and the programmable hall element is fixed on the retainer, and fixes through the packing filling.
Said induction targets piece is corresponding with the magnet positions in the said sensor body, and the gap is 0.5mm～2.5mm.
Advantage of the present invention is; Overcome owing to temperature, fit up gap, design tolerance bring signal errors; Sensor body and magnet are integrated simultaneously; Be fixed in gearbox inside and avoid dust absorption and influence signal, and can be through demarcating the gearbox that the neutral gear scope adapts to different gearshift displacements, versatility is better.Its manufacturing process is simple, and versatility is stronger, and is safe and reliable; Can make the fuel economy of vehicle better at whole neutral gear zone induction neutral gear signal.

Embodiment
Combine accompanying drawing and embodiment that the present invention is described further at present; Referring to Fig. 1 to Fig. 4; Contactless neutral gear sensor comprises induction targets piece 1 and sensor body 3, and induction targets piece 1 is fixed on the gear shift control axle 2; Sensor body 3 is fixed on the gear shift control axle fixed body 4, and gear shift control axle fixed body 4 is fixed on the gear box casing.Said sensor body 3 is in the housing 5 programmable hall element 9 to be housed, and programmable hall element 9 one sides are pasted with magnet 7, and programmable hall element 9 is fixed on the retainer 6, and fixes through packing 8 fillings.Said induction targets piece 1 is corresponding with magnet 7 positions in the said sensor body 3, and the gap is 0.5mm～2.5mm.
Embodiment 1:Contactless neutral gear sensor comprises induction targets piece 1 and sensor body 3, and the induction targets piece 1 that uses low carbon steel to process is ring-type, and a side is provided with a projection, and induction targets piece 1 is sleeved on the gear shift control axle 2 through interference fit.Sensor body 3 is fixed on the gear shift control axle fixed body 4, and gear shift control axle fixed body 4 is fixed on the gear box casing.Sensor body 3 is in the housing 5 programmable hall element 9 to be housed, and programmable hall element 9 one sides are pasted with magnet 7, and programmable hall element 9 is fixed on the retainer 6, and fixes through insulation filler 8 fillings.Said induction targets piece 1 is corresponding with magnet 7 positions in the said sensor body 3, and the gap is 1.5mm.
Embodiment 2:Contactless neutral gear sensor; Comprise induction targets piece 1 and sensor body 3; The induction targets piece 1 that uses low carbon steel to process is cuboid, and the centre is provided with the hole with gear shift control axle 2 equal diameters, and the hole of induction targets piece 1 is sleeved on the gear shift control axle 2 through interference fit.Sensor body 3 is fixed on the gear shift control axle fixed body 4, and gear shift control axle fixed body 4 is fixed on the gear box casing.Said sensor body 3 is in the housing 5 programmable hall element 9 to be housed, and programmable hall element 9 one sides are pasted with magnet 7, and programmable hall element 9 is fixed on the retainer 6, and fixes through 8 fillings of epoxy resin packing.Said induction targets piece 1 is corresponding with magnet 7 positions in the said sensor body 3, and the gap is 2.0mm.
The present invention is through induction targets piece 1 and 3 motions of sensor body, makes programmable hall element 9 that signal condition is offered engine management system.When gear shift Control Shaft 2 drives 1 motion of induction targets piece in gearshift procedure; The motion of the induction targets piece 1 that is processed by low carbon steel causes the intensity in magnet 7 magnetic fields to change, and the Strength Changes in magnet 7 magnetic fields is by 9 inductions of programmable hall element and produce signal, when signal amplitude reaches when demarcating threshold value; Meeting drive integrated circult module; Produce the neutral gear signal, make the neutral gear signals reverse, output neutral gear complementary signal through circuit design.If gear rests on the neutral gear, neutral gear signal output high level signal; If gear is in gear, the output gear signal is a high level signal, and promptly the neutral gear signal is a low level; When gear shift Control Shaft 2 is selecting in the shelves process, because induction targets piece 1 does not change magnitude of field intensity, do not change the programmable hall element state, contactless neutral gear sensor keeps original signal condition, promptly is in neutral state.Make engine management system make handled,, reduce pollution emissions to reach the raising VE Vehicle Economy in neutral position.The present invention can measure the neutral gear signal in a wider context, adapts to the gearbox of different model simultaneously through the angle of demarcating gearshift, and versatility is better; Make the generation signal be divided into two-way through circuit design, two paths of signals is complementary, offers control unit and is used for diagnosis and fault treatment, improves security of system.
