Motion or force take-off device for motor vehicles
First Claim
1. A power transmission device for transmitting power from a motor vehicle wheel to a driven machine, or from a driving machine to said motor vehicle wheel, comprising:
- a box frame, two parallel pulley shafts mounted for rotation in said box frame, each of said pulley shafts having a cylindrical outside surface extending along an axis, circular shaft ribs disposed on said outside surface which extend in juxtaposed planes perpendicular to said axes, an endless belt extending between and surrounding said pulley shafts, said belt having an inner surface provided with longitudinal juxtaposed belt ribs interfitting with said shaft ribs, said belt having a width at least as great as the width of the motor vehicle wheel and having an outside surface frictionally engaging said wheel, a distance between said pulley shafts causing said wheel to bear on said pulley shafts and on a portion of said belt facing said wheel and extending between said pulley shafts, at least one of said pulley shafts being connected to said driven or driving machine, a bottom frame lying under said box frame, said box frame being pivotally mounted on said bottom frame about a swivel axis, said swivel axis being substantially perpendicular to said belt and extending in a plane transverse to said pulley shafts, situated in an axially median region thereof.

Abstract
The field of the invention relates to installations for transmitting motion or power to any measuring apparatus or to apparatus requiring a rotary drive. The device of the invention comprises a box frame, and an endless belt rotating over two parallel pulley shafts driving an external transmission system. Said belt and the pulley shafts are of the poly-V type in order to prevent the belt from slipping sideways off of the pulleys, and to prevent the vehicle escaping the frame. The box frame is pivotally mounted on a swivel frame which is free to swivel relative to a fixed frame in order to keep the belt in alignment with the vehicle wheel, either by direct adjustment or by automatic adjustment. The assembly is mounted on shock absorbers, and its height may be adjusted by standing it on an elevator platform. The speed of rotation of the vehicle engine is regulated by a tachometer and a regulator assembly.
