The body of the first chock is essentially a mirror-image of the second chock body. The low profile of a wheel chock allows each to be positioned under a vehicle the rocker panel of which has its lower edge only 148 mm (5.82 inches) above the surface upon which the vehicle's tire rests, so that the installed chock height is reduced to 47.6 mm (1.87″) under the components of the vehicle's body. The assembly may include a pair of “active” chocks; or, one active chock and one anchor chock. A single window in the upper portion of the stepped-box provides access for a strap of a wheel harness, which strap is wrapped around a torque tube in an active chock. The torque tube in one chock is rotatable in a direction opposite to that of the torque tube of the other chock. With a pair of active chocks, hooks on straps of a prior art harness are eliminated because it is difficult and time-consuming to manipulate a tire harness with its straps and hooks to secure the tire between the wheel chocks. When one chock is an anchor chock, one end of the strap is provided with a hook which is anchored to a rod or tube which is substituted for the rotatable torque tube. | 2009-08-20 |

The radial dimension of the annual passage should be keep as uniform as possible so as not to cause unwanted variations in the reaction. This has proven difficult in prior constructions owing to the small radial dimension (e.g. 50-300 micrometers) and inevitable manufacturing tolerances in the bearings supporting the rotor. In apparatus of the invention the rotor is suspended within the stator passage by a flexible connection between the drive motor shaft and the rotor and uniformity is maintained by the so-called hydrodynamic effect which will become operative in such a narrow passage. Thus, if any part of the rotor surface moves radially from the central position closer to the stator surface the liquid viscosity produces a force that moves the rotor back to the central position. Preferably the flexible connection consists of two serially connected flexible connectors. | 2009-08-20 |
