Abstract
The utility model discloses an electronic induction counting device of a speedometer of a motorcycle, belonging to the technical field of an electronic induction counter. The electronic induction counting device comprises a sensor and an induction body that are arranged in a relative rotation way; the sensor is connected with the speedometer of the motorcycle by a lead; the sensor is fixed on a front axle of the motorcycle; the induction body is fixed in an end cover of a barrel body; an opening end of the barrel body is fixed on a front rim flange of the motorcycle; the front rim flange is rotatably arranged on the front axle by a bearing; and the axial inductive gap is left between the sensor and the induction body, thereby ensuring the fixed inductive gap between the induction body and the sensor of the electronic induction counting device and avoiding the damage to the sensor by the induction body caused by the too small inductive gap or inaccurate counting of the speedometer caused by the too big inductive gap in the driving process. The electronic induction counting device has reasonable structure and can be widely applied in the production and manufacturing industry of motor tricycles.
Description
Technical field
The utility model relates to electronic induction counter technical field, relates in particular to a kind of electronic induction counting assembly that is used for motorcycle speed of a motor vehicle mileometer.
Background technology
At present, what the mileometer of most of motor tricycles used is worm and gear cable type machinery mileometer, its signal transfer mode is the contact transmission, mutual friction mutually between flexible axle and the axle sleeve, when vehicle wheel rotational speed when higher, the accuracy of this mileometer is not very high, also exists flexible axle simultaneously and ruptures easily, causes mileometer to be scrapped.
The motor tricycle that has has adopted electronic odometer, its signal transfer mode is contactless transmission, in recent years along with the raising of industrial level, the motor tricycle that has is being adorned Hall element formula counter, for example Chinese utility model patent CN2570791Y, the disclosed electronic speed sensor of instructionss such as CN2867348Y, solved the defective that the contact speed pickup exists, but because of structural design unreasonable, general magnet steel all be installed in the synchronous rotation axis of wheel on, sensor is installed on the fixing outer cover, induction gap between magnet steel and the sensor is very little, because the existence of machining precision own or alignment error, in the vehicle ' process, produce diameter run-out, the phenomenon that the magnet steel dish breaks the Hall element probe often takes place, perhaps respond to excesssive gap because diameter run-out makes, produce recording error, the vehicle speed mileage data that reflect on instrument are because error accumulation is bigger with real vehicle speed mileage gap.
The utility model content
Technical problem to be solved in the utility model is: a kind of electronic induction counting device for motorcycle speedometer is provided, the inductor of assurance electronic induction counting assembly and the induction gap between the sensor are fixed, avoided in the process of moving perhaps responding to excesssive gap and causing the speedometer counting inaccurate because the too small inductor that causes in induction gap damages sensor.
For solving the problems of the technologies described above, the technical solution of the utility model is: electronic induction counting device for motorcycle speedometer, comprise the sensor and the inductor that relatively rotate installation, and described sensor is connected with the speedometer of described motorcycle by lead; Described sensor is fixed on the front axle of described motorcycle; Described inductor is fixed in the end cap of a cylindrical shell, and the openend of described cylindrical shell is fixed on the front rim flange of described motorcycle; Described front rim flange is rotated by bearing and is installed on the described front axle; Has axial induction gap between described sensor and the described inductor.
As a kind of improvement, described sensor is a Hall element, and described inductor is a magnet steel.
As further improvement, described front axle is provided with axially extending bore, and described lead runs through described through hole.
As further improvement, the lead traversing through end of described through hole is provided with seal.
Owing to adopted technique scheme, the beneficial effects of the utility model are: owing to inductor and sensor are installed in respectively on the cylindrical shell that rotates synchronously with wheel and the front axle of fixing in relative rotation, has axial induction gap between sensor and the inductor, in the process of moving, avoided the diameter run-out that causes because of machining precision or alignment error influence to the induction gap, even certain diameter run-out is arranged between vehicle front-wheel axle and the rim shoulder, just make the axis of inductor and the axis of sensor depart from, but can not make the probe that in rotation process, damages sensor of inductor, be unlikely to make the induction excesssive gap yet and cause the vehicle speed mileage counting inaccurate.
Because front axle is provided with axially extending bore; the lead of sensor passes from through hole; the lead traversing through end of through hole is provided with seal; lead is sealed in the through hole; make that the lead of sensor can not be damaged in the process of moving; protect the lead of sensor, reduced dust and rainwater simultaneously and entered into the electronic induction counting assembly, influenced its counting precision.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model example structure synoptic diagram;
Fig. 2 is the cut-open view of A-A among Fig. 1;
Among the figure: 1, rim shoulder, 2, magnet steel, 3, cylindrical shell, 31, end cap, 4, Hall element, 5, front axle, 6, seal, 7, lead.
Embodiment
As depicted in figs. 1 and 2, a kind of electronic induction counting device for motorcycle speedometer comprises the sensor and the inductor that relatively rotate installation, and sensor is preferably Hall element 4, inductor is preferably magnet steel 2, and Hall element 4 is connected with the speedometer of motorcycle by lead 7; Hall element 4 is fixed on the front axle 5 of motorcycle; Magnet steel 2 is fixed in the end cap 31 of a cylindrical shell 3 by multiple mode such as inlaying or bonding, and the openend of cylindrical shell 3 is fixedly installed on the front rim flange 1 of motorcycle by screw thread or flange; Front rim flange 1 is rotated by bearing and is installed on the front axle 5; Have axial induction gap between Hall element 4 and the magnet steel 2, the setting value in induction gap is 1～3 millimeter.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the present utility model.
