Deadweight detection device for whole vehicle and detecting method thereof based on oil gas or air spring

Abstract

The invention relates to the technical field of automobile weight detection, in particular to a finished automobile deadweight detection device and a detection method thereof based on an oil-gas suspension or an air suspension. In order to solve the problem that the weighing of an automobile is limited by time and place in the prior art, the invention provides the finished automobile deadweight detection device based on the oil-gas suspension or air suspension. The device comprises an automobile suspension elastic element, a pressure sensor and a signal processor, wherein the pressure sensor is arranged on the automobile suspension elastic element and the pressure sensor is connected with the signal processor. The finished automobile deadweight detection device and the detection method thereof can be directly applied to heavy off-road vehicles and platform lorries. As vehicles are provided with oil-gas suspensions and air suspensions widely, and have considerably broad prospect in the next decades, the device and the method thereof can be applied widely, and can weigh the vehicles which needs to be weighed at any time and place.

Description

technical field [0001] The invention relates to the technical field of vehicle weight detection, in particular to a vehicle self-weight detection device and a detection method based on an oil-gas or air suspension. Background technique [0002] The measurement of vehicle gross weight is already a very mature technology. The widely used "pound room" can measure the weight of the whole vehicle by driving the car into it; the more professional axle load measuring instrument can accurately measure the axle load of the car by placing the axle load measuring instrument under the wheel. Load, calculate the weight of the vehicle. However, these mature technologies all have common disadvantages: they must be at a fixed location, and the car must be driven into the "weight room" to be measured; the tonnage is limited. To the large tonnage "pound room". In addition, when the car is loaded with goods at the dock, media factory, mine, construction site, etc., it becomes very difficult...

Problems solved by technology

However, these mature technologies all have common disadvantages: they must be at a fixed location, and the car must be driven into the "weight room" to be measured; the tonnage is limited. To the "pound room" of large tonnage

In addition, when the car is loaded with goods at the dock, media factory, mine, construction site, etc., it becomes very difficult or even impossible to measure the weight of the whole vehicle; Loading cargo without compromising driving safety due to overloading
