Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the embodiment shown in accompanying drawing:

[0016] refer to Figure 1~4 : a kind of road transport vehicle eccentric load detection device that the present invention relates to, is particularly suitable for the road transport vehicle that adopts leaf spring as suspension system, comprises reflector 4, photoelectric position sensitive sensor 6, semiconductor The laser 7 and the reflector 4 are placed in the box body 3, and the box body 3 is fixed on the end of the leaf spring 1 by corresponding fixtures, such as the outer side of the leaf spring 1 near the lifting lug 2 or the spring support 9, and the photoelectric position sensitive sensor 6. The semiconductor lasers 7 are fixed horizontally side by side in the middle box body 5, and the middle box body 5 is also fixed on the outer side of the middle part of the leaf spring 1 by corresponding clamps. The reflector 4 and the photoel...

Abstract

The invention relates to a highway transport vehicle unbalance-loading detecting device, comprising a semiconductor laser (7), a photo-potential sensitive sensor (6) and a reflecting mirror (4); the semiconductor laser (7), the photo-potential sensitive sensor (6) and the reflecting mirror (4) are respectively arranged at the outer side of steel plate springs (1) at the two sides of an axle; wherein, the semiconductor laser (7) and the photo-potential sensitive sensor (6) are fixed at the outer side of the middle part of the steel plate springs (1) side by side, and the reflecting mirror (4) is fixed at the same side near the end parts of the steel plate springs (1); the mirror surface of the reflecting mirror (4) is right opposite to the photo surface of the photo-potential sensitive sensor (6), laser ray transmitted by the semiconductor laser (7) and reflected by the reflecting mirror is coincided with the center of the photo surface of the photo-potential sensitive sensor when the vehicle is in idle load; when the vehicle is in full load, the reflection ray falls in the photo surface of the photo-potential sensitive sensor (6). The device has simple structure, and can accurately judge the unbalance loading of the operating vehicles, thus providing necessary guarantee for safety operation of the highway transport vehicles.

Description

Technical field: [0001] The invention relates to an eccentric load detection device for a road transport vehicle, which is mainly suitable for a road transport vehicle using a leaf spring as a suspension system, and belongs to the technical field of road transport vehicle safety detection. Background technique: [0002] The unbalanced load of road transport vehicles is an extremely important factor causing traffic safety accidents, especially in the case of high speed, emergency steering, etc., the unbalanced load of vehicles can easily cause rollover and cargo falling off, resulting in vicious traffic accidents. Existing road transport vehicle load measurement methods mainly involve the weighing of the vehicle axle load and the total vehicle weight, and rarely involve the unbalanced load of each axle of the vehicle, that is, the detection of the vehicle's unbalanced load. Invention content: [0003] The purpose of the present invention is to provide a road transport vehic...
