Problems solved by technology

[0004] At present, most of the weighing methods for load-bearing vehicles are through the weighbridge or the external weighing system, and the weighing data during the driving process of the vehicle cannot be obtained in real time; if the corresponding sensor is installed on the vehicle, the weighing data can be directly measured. But the corresponding sensor position is quite difficult to choose
In order to better obtain real load data, it

Abstract

The invention discloses a sensing system by detecting deformation quantity of a vehicle axle housing to weigh the load. The weighing sensing system based on deformation quantity detection of the vehicle axle housing comprises a sensing element and a data processing device; and the weighing sensing system also comprises an elastic body for carrying the sensing element, wherein the sensing element is arranged inside the elastic body, and the elastic body is arranged on a neutral plane position on the surface wall of the vehicle axle housing. Due to the adoption of the weighing sensing system based on the deformation quantity detection of the vehicle axle housing, technical weaknesses of the prior art that detection data cannot reflect the real load situation and the service life of the sensing element is influenced because the stress deformation can cause unnecessary internal stress influence on the sensing element can be overcome, relative precision of the detection can be realized, and the sensing element can be effectively protected.

Description

[0001] Technical field [0002] The invention belongs to the field of weighing sensing, and particularly relates to a sensing system that achieves the purpose of load weighing by detecting the deformation of the automobile axle housing. Background technique [0003] Sensing elements are the forefront and most important components for obtaining information in engineering inspection systems. Its task is to convert the information (mostly non-electricity) that is of interest to the measured object or production (mostly non-electricity) into a corresponding signal (mainly electricity) that is easy to process and transmit. The device that takes the sensor element as the core, is equipped with a certain supporting and fixing mechanism, and is connected by mechanical and electrical means to transmit the obtained signal is called a sensor. [0004] At present, the weighing method of heavy vehicles is mostly through the platform scale or external weighing system, which cannot obtain the wei...
