Abstract
A drive system for a rotary-, pivot- and propelling-drive of a vehicle especially for an excavating machine with a planetary gear transmission and a brake installation that includes a brake disk with brake surfaces which are arranged between brake lamellae. A support of the brake lamellae takes place by way of teeth for the planet wheels of the transmission which are already present on the inside of the housing (in a ring gear) whereby the hub of the brake disk is axially displaceably retained in already present teeth of the sun gear of the transmission.
