Abstract
The utility model relates to a non-contact type gear sensing device. The non-contact type gear sensing device comprises a gear-shifting drag arm and a gear sensor, wherein the gear-shifting drag arm is fixedly connected with a magnetic induction device, the gear sensor is arranged in the induction range of the magnetic induction device, the gear sensor and the magnetic induction device are independently installed, when gear-shifting operation is carried out, the magnetic induction device rotates along with the gear-shifting drag arm, further the relative positions of the magnetic induction device and the gear sensor change, the variation of magnetic flux of the magnetic induction device is received through the gear sensor, and therefore the gear sensor monitors gear information variations, signals are output accurately and stably, and the service life of the gear sensor is long.
Description
Technical field
The utility model relates to a kind of shift sensing device, specifically, relates to a kind of contactless shift sensing device, belongs to field of mechanical technique.
Background technique
Shift sensor is mounted in a kind of angle transducer on automatic gearbox, be mainly used in automatic gearbox control system, the automatic transmission shift axle position information that automatic gearbox control system provides by shift sensor is implemented accurate motion control, realizes the combination of moving gear shift and swing gearshift and the clutch of transmission shift fork shaft.Shift sensor is most important observing and controlling link in automatic transmission control system, and whether the measurement of shift sensor has accurately determined reliability, the Security of automatic transmission and the smoothness of controlling.At present, conventional shift sensor mostly belongs to contact-type shift sensor.
In realizing process of the present invention, inventor finds at least to exist in prior art following problem, touch sensor adopts piece-picking type structure more, when gearshift is rotated, plectrum is connected with contact, owing to frequently sliding in contact, parts easily produce wearing and tearing, cause bad connection, cannot guarantee accuracy and the stability of signal output, be restricted working life.
Model utility content
The technical problems to be solved in the utility model is for above deficiency, a kind of contactless shift sensing device is provided, the accuracy of output signal in prior art and poor stability and shift sensor short defect in working life have been overcome, adopt after shift sensing device of the present utility model, there is accuracy and good stability and the shift sensor long service life of output signal.
For solving above technical problem, the utility model by the following technical solutions: a kind of contactless shift sensing device, is characterized in that: described shift sensing device comprises gearshift torque arm and shift sensor;
Described gearshift torque arm is fixedly connected with magnetic-inductive device;
Described shift sensor is arranged in the induction range of described magnetic-inductive device.
An optimized project, described shift sensor is connected with sensor stand, and sensor stand is fixedly connected with gear box casing.
The utility model adopts after above technological scheme, compared with prior art, have the following advantages: gearshift torque arm is fixedly connected with magnetic-inductive device, in the induction range of magnetic-inductive device, be provided with shift sensor, shift sensor is fixedly connected with gear box casing, shift sensor and magnetic-inductive device be independent installation respectively, while shifting gears operation, magnetic-inductive device rotates with gearshift torque arm, and then cause the relative position of magnetic-inductive device and shift sensor to change, the magnetic flux that receives magnetic-inductive device by shift sensor changes, thereby realize the monitoring of shift sensor to gear information change, output signal is accurate, stable, and the long service life of shift sensor.
Below in conjunction with drawings and Examples, the utility model is elaborated.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of shift sensing device in the utility model embodiment;
Accompanying drawing 2 is another structural representations of shift sensing device in the utility model embodiment;
In figure,
The 1-torque arm of shifting gears, 2-shift sensor, 3-magnetic-inductive device, 4-sensor stand, 5-shifting shaft.
Embodiment
Embodiment, as depicted in figs. 1 and 2, a kind of contactless shift sensing device, comprise gearshift torque arm 1 and shift sensor 2, gearshift torque arm 1 is fixedly connected with magnetic-inductive device 3, shift sensor 2 is arranged in the induction range of described magnetic-inductive device 3, and shift sensor 2 is connected with sensor stand 4, and sensor stand 4 is fixedly connected with gear box casing.
Magnetic-inductive device 3 and shift sensor 2 be independent installation respectively, gearshift torque arm 1 is fixedly connected with shifting shaft 5, when shifting shaft 5 rotates, gearshift torque arm 1 is rotated with magnetic-inductive device 3 thereupon, relative position between magnetic-inductive device 3 and shift sensor 2 changes, magnetic flux by shift sensor 2 changes thereupon, shift sensor 2 is by the variation output signal of induced flux, the rotation of indirect monitoring shifting shaft 5, contactless, effectively avoided the defect of long duration of action lower contact easy-to-rust wearing and tearing, output signal is accurate, stable, and the long service life of shift sensor.
The above is giving an example of the utility model preferred forms, and the part of wherein not addressing is in detail those of ordinary skills' common practise.Protection domain of the present utility model is as the criterion with the content of claim, and any equivalent transformation carrying out based on technology enlightenment of the present utility model, also within protection domain of the present utility model.
