DISPOSITIVO DE EMPUJE PARA MOTORES DE ARRANQUE DE MOTORES DE COMBUSTION INTERNA.

摘要

An axially shiftable rotatable rod is mounted with radial clearance in the hollow output shaft of a motor. A pinion is fixed on the rod and at least in part located outwardly beyond the shaft so that it can mesh with a gear of a combustion engine to be started. A sleeve surrounds the rod fixed with the pinion and has an outer steep-pitch thread. A motion-transmitting coupling is provided including a first coupling element mounted in the shaft for rotation therewith and a second coupling element carried by the sleeve for rotation therewith. The coupling elements are provided with mechanically interlockable coupling projections and damping means is located between the sleeve and the first coupling portion and serves for damping axially directed forces.
