Abstract

See full text

A tamping unit for tamping sleepers of a track includes a lowerable tool carrier and oppositely positioned tamping tools. Each tamping tool is connected via a pivot arm to a squeezing drive for producing a squeezing motion and to an electric vibration drive for producing a vibratory motion. The electric vibration drive includes an eccentric shaft which, together with a rotor of an electric motor, is mounted merely in an eccenter housing. A stator of the electric motor with a motor housing is flange-mounted to the eccenter housing. As a result of the omission of a separate motor mounting, the motor housing has a particularly small overall depth.
