A commercial vehicle suspension system motion track vehicle measurement system and measurement method thereof

Abstract

A commercial vehicle suspension system movement track vehicle measurement system, including four cable sensors, two measuring points located on the front axle and no relative movement with the front axle during vehicle driving, four cable sensors and two measuring points The points are all located on the same plane, and the four wire sensors are fixed side by side on the outside of the frame longitudinal beam. Every two wire sensors are connected to a measurement point, and the four wire sensors are connected to the signal processor. Under normal circumstances, the signal processor receives the detection signals from the No. 1 cable sensor, the No. 2 cable sensor, the No. 3 cable sensor, and the No. 4 cable sensor in real time, and fits the motion trajectory of the front axle according to these signals, that is, the vehicle under different working conditions can be obtained. The trajectory of the vehicle suspension system. The design not only has high measurement accuracy, but also has a simple structure and measurement method.

Description

technical field [0001] The invention belongs to the technical field of vehicle testing, and in particular relates to a vehicle measurement system and a measurement method for the movement trajectory of a commercial vehicle suspension system. Background technique [0002] In the actual use of commercial vehicles, there are often phenomena such as interference deviation during braking, steering wheel shimmy on bumpy roads, etc. In response, it is necessary to obtain the movement trajectory of the suspension system under various working conditions, so as to adjust and improve the steering system and the amount of motion interference between the suspension system. [0003] For the determination of the amount of motion interference of the steering system and suspension system of a commercial vehicle, Chinese patent: application publication number CN108007700A, the invention patent of the application publication date of May 8, 2018 discloses a motion interference amount of the ste...

Problems solved by technology

[0004] The test system needs to be carried out on a bench. On the one hand, a special bench needs to be built, which is costly; The frame test results cannot approach the real value. At the same time, because the system needs to collect and convert the road load data of the real vehicle, the test cycle is long
