Listening clamp for a vibroacoustic diagnosis tool used mainly in the automotive industry

摘要

The invention relates to a clamp (10) which is used mainly in a vibroacoustic diagnosis tool during an automobile maintenance or after-sales assistance opération, including two hinged arms (11, 12), each comprising a jaw (13, 14) at one end and a handle (15, 16) at the other end. A pad (20) is mounted on each jaw (13, 14) via a ball-and-socket joint (21), such that the pad (20) ensures effective contact between the clamp (10) and the part being tested, and séparâtes the body of the clamp from the listening part. The invention is useful in the field of motor vehicles. The invention is also useful in the vibroacoustic diagnosis of motor vehicles or motor vehicle subunits.

主权项

1. A listening clamp for an acoustical vibration analysis tool, the listening clamp comprising a body formed of two arms hingedly connected and pivotable about an axis of articulation, each arm comprising a jaw at one end and a handle at another end, the arm further comprising a pad mounted in each jaw by means of a swiveling articulation such that the pad ensures contact between the listening clamp and a structure to be tested while decoupling the body from the structure; the listening clamp further comprising an accelerometer; at least one of the pads comprising a plate pivotally mounted to the jaw to which the at least one pad is mounted and a ball which is in contact with and protrudes from the plate, the ball being operative to collect the vibrations coming from the structure to be tested; said accelerometer being mounted to one of said at least one pad and said jaw.
