Abstract
A vehicle level detector detects a change in the elevation of a vehicle body as reflected in a change in the relative distance between a suspension member for wheels of the vehicle and the vehicle body. The detector comprises a magnet and a magnetoelectric transducer element disposed in opposing relationship. One of the magnet and the transducer element is disposed for displacement relative to the other in accordance with a varying elevation of the vehicle body, thus permitting a change in the elevation of the vehicle body to be detected by sensing the displacement.
Claims19
A vehicle level detector which detects a change in the elevation of a vehicle body as reflected in a change in the relative distance between a suspension member and a lower surface of the vehicle body, comprising at least two magnetoelectric transducer elements which are fixedly mounted on the lower surface of the vehicle body and spaced apart a given distance, a movable magnet disposed in opposing relationship with the transducer elements, and an actuating member connected between the magnet and the suspension member for actuating the magnet in accordance with a change in the relative distance between the suspension member and the vehicle body, a displacement of the magnetic selectively activating or deactivating the transducer elements, thereby producing a signal indicative of the elevation of the vehicle body.
A vehicle level detector for detecting a change in the elevation of a vehicle body as reflected in a change in relative distance between a suspension member and the vehicle body, comprising:
- a detector housing secured on a vehicle body;
- a magnet and magnetoelectric transducer element disposed within said detector housing in opposing relationship, one of said magnet and magnetoelectric transducer element is secured on the internal surface of said detector housing and the other is movable with respect to said one of them secured on said housing,
- whereby said the other one movable with respect to the one secured to said detector housing being adapted to be displaced relative to one another corresponding to varying of the vehicle body.
A vehicle level detector for detecting a change in the elevation of a vehicle body as reflected in a change in relative distance between a suspension member and the vehicle body, comprising:
- a detector housing secured on the lower surface of the vehicle body;
- a magnet and magnetoelectric transducer element disposed within said detector housing in opposing relationship, said magnetoelectric transducer element being secured to the internal surface of said detector housing and said magnet being movable relative to said magnetoelectric transducer element,
- whereby said transducer element and said magnet being adapted to be displaced relative to the other corresponding to varying of elevation of the vehicle body with respect to the suspension member.
A vehicle level detector for detecting a change in the elevation of a vehicle body as reflected in a change in the relative distance between said vehicle body and a suspension member, comprising:
- a hollow detector housing secured onto the lower surface of said vehicle body;
- and
- a magnet and a magnetoelectric transducer element disposed within said detector housing in opposing relationship, said magnetoelectric transducer element being secured on the internal periphery of said detector housing and having at least two poles each of which are located in aparted relationship with respect to the other and said magnet being substantially vertically movable with respect to said transducer element corresponding to varying of relative distance between said vehicle body and suspension member.
A vehicle level detector for detecting a change in the elevation of a vehicle body as reflected in a change in the relative distance between said vehicle body and a suspension member, comprising:
- a detector housing secured onto the lower surface of said vehicle body;
- a magnet and magnetoelectric transducer element disposed within said detector housing in opposing relationship with respect to one another, said transducer element being secured onto the internal periphery of said detector housing and have at least two poles in aparting relationship with respect to one another and said magnet being substantially vertically movable with respect to said transducer element;
- a means for connecting said magnet to said suspension member to transmit relative displacement between said vehicle body and said suspension member and thereby to move said magnet with respect to said transducer element corresponding to varying of distance between said vehicle body and said suspension member.
- in the relative distance between the suspension member and the vehicle body, a displacement of the magnet selectively activating or deactivating the transducer elements, thereby producing a signal indicative of the elevation of the vehicle body.
