Abstract
Abstract A noise absorbing member is positioned at the speedometer end of the speedometer cable extending from the transmission for absorbing noise vibrations due to the mechanical coupling between the cable and the speedometer. In addition, the noise absorbing member axially aligns the cable and the driven members of the speedometer providing a smoother responding speedometer indicator dial absent flutter.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
204 words
In a motor vehicle speedometer drive arrangement including: a drive member having a rate of rotation responsive to the speed of the vehicle; a flexible shaft having one end thereof coupled to said drive member for transmitting the rotational motion of said drive member, the other end of said flexible shaft terminating in an elongated tip having a substantially rectangular cross section; a speedometer frame member having an extending tubular cylindrical section; an elongated magnet shaft journalled for rotation in the tubular cylindrical extension of said frame member having means at one end adapted for receiving the rectangular core tip of said other end of said flexible shaft; a magnet connected to the other end of said magnet shaft and rotatably driven by the rotational motion of said flexible shaft generating a magnetic field; and an indicating means responsive to said magnetic field for indicating thE speed of the vehicle, the improvement comprising: a cylindrical tubular noise absorbing member encircling said core tip adapted to be compressively received in said one end of said magnet shaft, said member axially aligning said flexible shaft in said magnet shaft and having an inner diameter that is less than the cross-sectional diagonal dimension of the core tip,
Claim 2
Dependent Claim
