Description
Technical Field
The invention relates to the technical field of processing and manufacturing of snow sweeper, in particular to a device for mounting a drive axle angle sensor on a snow sweeper.
Background
At present, on airport snow removing equipment and road snow removing equipment, in order to accurately measure the angle conversion and displacement of a drive axle and cannot increase the load of the drive axle, an angle sensor of the drive axle is generally arranged on hydraulic oil cylinders of a front drive axle and a rear drive axle, such as the hydraulic oil cylinder 10 in fig. 1, and the angle sensor generally rotates an integral displacement sensor. Because the displacement sensor is arranged inside the oil cylinder, when the oil cylinder works, the pressure inside the oil cylinder is high, the displacement sensor is soaked in high-pressure hydraulic oil for a long time, the service life is influenced, and the replacement cost is high.
Disclosure of Invention
The invention aims to solve the problem that the service life of a sensor is short and the replacement cost is high due to the fact that the conventional mounting position of a drive axle angle sensor of a snow sweeper is not proper.
In order to solve the problems, the technical scheme of the invention is as follows: this snow sweeper transaxle angle sensor installation device is including installing the angle sensor between front drive axle and rear drive axle, angle sensor is the non-contact magnetic induction formula rotation angle sensor including sensor magnetic head and sensor response end, angle sensor installs under the pivot that turns to between front drive axle and the rear drive axle on the left side or the right of the direction of travel, it is equipped with the apron to turn to the pivot bottom, the apron in the below that turns to the pivot is equipped with the recess, sensor response end install in the recess bottom of apron, sensor magnetic head install in directly over the sensor response end turn to the pivot bottom, sensor magnetic head bottom surface with there is interval space between the sensor response end top surface.
In the above technical solution, a more specific solution may be: the cover plate is arranged at the bottom of the swing arm on the outer side of the lower part of the steering shaft pin.
Further: and a sensor mounting seat is arranged at the bottom of the steering shaft pin right above the groove of the cover plate, and the sensor magnetic head is mounted at the bottom of the sensor mounting seat.
Further: the sensor mounting seat and the sensor magnetic head are both positioned in the cover plate groove.
Due to the adoption of the technical scheme, compared with the prior art, the invention has the following beneficial effects:
this snow sweeper transaxle angle sensor installation device chooses for use the non-contact magnetic induction formula rotation angle sensor who includes sensor magnetic head and sensor response end, this kind of sensor reliability is high, high durability and convenient installation, the cost is low, and install it under the pivot of turning to between the front drive axle on the left side of direction of travel or the right and the rear drive axle, when the transaxle turns to, the sensor magnetic head of installing on the pivot of turning to is quiescent condition, install the sensor response end in the swing arm and rotate with the center that turns to the pivot, when sensor magnetic head and sensor response end relative rotation motion, the sensor response end is through the change of judging the transaxle angle with the magnetic field change that the sensor magnetic head produced, the problem that the sensor is damaged by pressure in the hydro-cylinder for a long time has both been solved, can be accurate measure.
