Abstract
The utility model discloses a hub-type vehicle speed sensing device which comprises a vehicle frame, a hub, a permanent magnet and a Hall element, wherein the hub is mounted on the vehicle frame in a rotating manner through a bearing, the permanent magnet is mounted on the hub, the Hall element is mounted on the vehicle frame, and the position where the Hall element is mounted on the vehicle frame faces the permanent magnet on the hub. Since the permanent magnet and the Hall element are mounted on the hub and the vehicle frame respectively and face each other with a certain distance, the vehicle speed is detected by sensing the change in magnetic field of the permanent magnet through the Hall element. The hub-type vehicle speed sensing device has the advantages of simple structure and rapid response.
Description
Technical field
The utility model relates to a kind of motor vehicle, particularly relates to a kind of hub-type speed of a motor vehicle induction installation.
Background technology
General motorcycle is shown in the speed of a motor vehicle on the instrument panel; The speed of a motor vehicle induction installation that is the wheel through being installed in motorcycle is mostly reached; And speed of a motor vehicle induction installation was that main this mechanical type speed of a motor vehicle induction installation also has its shortcoming with the mechanical type in the past: (1) sensitivity is not enough: when the wheel of motorcycle to slowly run; The beat of pointer amplitude of this instrument panel is very little, even does not change.(2) reaction time is long: under speed sharply changed, the pointer of this instrument panel can't change at once thereupon, and it is because due to the characteristic of the material of the inertia of physical construction itself and physical construction itself.
The utility model content
The purpose of the utility model is to provide a kind of sensitive hub-type speed of a motor vehicle induction installation.
For realizing above-mentioned purpose, the technical solution of the utility model is:
The utility model is a kind of hub-type speed of a motor vehicle induction installation, and it comprises vehicle frame, wheel hub, permanent magnet, Hall element; Described wheel hub is installed on the vehicle frame through bearing is rotatable; Permanent magnet is installed on wheel hub, corresponding with the permanent magnet on the wheel hub at installation Hall element and Hall element on the vehicle frame in the installation position on the vehicle frame.
The profile of described permanent magnet is circular, square, strip.
After adopting such scheme, because the utility model permanent magnet is installed in respectively on wheel hub and the vehicle frame with Hall element, relative at interval, the changes of magnetic field of utilizing Hall element to respond to permanent magnet is detected the speed of a motor vehicle, and is simple in structure, be quick on the draw.
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the front elevation that the utility model permanent magnet is installed in first embodiment of wheel hub;
Fig. 3 is the front elevation that the utility model permanent magnet is installed in second embodiment of wheel hub;
Fig. 4 is the front elevation that the utility model permanent magnet is installed in second embodiment of wheel hub.
Embodiment
Like Fig. 1, shown in Figure 2, first embodiment of the utility model hub-type speed of a motor vehicle induction installation, it comprises vehicle frame 1, wheel hub 2, permanent magnet 3, Hall element 4.
Described wheel hub 2 is installed on the vehicle frame 1 through bearing is rotatable; Permanent magnet 3 is installed on the spoke 21 of wheel hub 2, corresponding with the permanent magnet 3 on the wheel hub 2 at installation Hall element 4 and Hall element 4 on the vehicle frame 1 in the installation position on the vehicle frame 1.
Like Fig. 3, shown in Figure 4, permanent magnet 3 also can be installed on the fitting surface 22 of wheel hub 2.
The profile of described permanent magnet can be other shapes such as circular, square or strip.
The emphasis of the utility model just is: utilize the changes of magnetic field of Hall element induction permanent magnet to detect the speed of a motor vehicle.
The above; Be merely the utility model preferred embodiment; The installation position of permanent magnet on wheel hub can have multiple; So can not limit the scope that the utility model is implemented with this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
Claims (2)
