Abstract
The instantaneous load sensor of a motor vehicle is incorporated in a suspension assembly of the vehicle, and comprises a suspension element (1) fastened via an elastic mechanism (3) to a rod (5) carried by a yoke (7). The rod (5) is a blind hollow tube, in which a slot (12) has been made substantially in the axis of the suspension element (1) and opposite the latter, so as to allow the elastic mechanism (3) to penetrate into the tube (5), a sensor (10) of the pressure prevailing in the tube hermetically closing the open end of the tube.
Claims1
A suspension assembly for a motor vehicle, comprising a suspension element fastened via elastic means to a rod carried by yoke ,and the rod including an instantaneous vehicle load sensor of the motor vehicle, the instantaneous load sensor comprising said rod being a blind hollow tube containing a fluid and in which a slot has been made substantially in an axis of said suspension element and opposite said suspension element so as to allow said elastic means to penetrate into and to move out of said hollow tube as an instantaneous function of vehicle loading, and a pressure sensor hermetically closing end of said tube and detecting a change in pressure of the fluid in said hollow tube as a result of said elastic means movement into and out of said hollow tube.
