ABSTRACT:
In a highly compact odometer an electric motor which drives a mechanical display thereof, is disposed within the set of annular figure wheels used in the display and drivingly connected to said wheels through a worm and worm wheel drive train. In the case of integrated "total" and "trip" odometers a multipole rotor having a torque capacity adequate for driving both odometers is disposed within the set of figure wheels used for the "total" odometer display while the coil is disposed within the "trip" odometer set. Yokes extend between the sets of wheels to provide a magnetic connection between the coil and rotor. To prevent reversing of the odometer and gear chatter in the drive train a one-way clutch type bearing is used to support the output shaft of the electric motor.
