Title:
MEASUREMENT SYSTEM FOR CALIBRATING AUTOMOBILE SPRING PARAMETER
Document Type and Number:
WIPO Patent Application WO/2018/072096
Kind Code:
A1
Abstract:
Provided is a measurement system for calibrating an automobile spring parameter, comprising: a mounting pit (11) recessed in the ground (10), two carrier plates (12) diposed across the mounting pit (12) from left to right; two force applying devices (20) provided at the left and right sides inside the mounting pit (11) respectively and provided with a jack (27), an oil passage to which the jack (27) is externally connected being connected to an oil pressure sensor (28); a chassis fixing device (30) provided around the mounting pit (11); and a deformation sensor (50) mounted at a spring (55) of a wheel (54). When the measurement system is used, an automobile (51) is parked on the ground (10), the wheel (54) is rolled on the two carrier plates (12), a chassis height of the automobile (51) is fixed by the chassis fixing device (30), the carrier plates (12) and the wheel (54) are lifted by the jack (27), the oil pressure sensor (28) measures a jacking force of the jack (27), the deformation sensor (50) measures a corresponding spring deformation amount, such that a relationship between the stress and deformation of the spring (55) of each wheel (54) can be calibrated. When the automobile (51) is loaded, the spring deformation amount of each wheel (54) is measured and converted to a stress, and then stresses are added up to obtain an overall load of the automobile (51).
