Abstract (en)
A drive mechanism (10) has a frame (16), a driven member (14) and a first element (20) rotatable relative to the frame (18). A driving element (24) is mounted on and rotatable with the first element (20). Apparatus (34), such as a hydraulic motor (40) and pinion gear (38), engages and rotates the driving element (24). Apparatus (36), such as a brake (42) and pinion gear (44) engages and controllably blocks the driving element (24) from rotation. Final drive apparatus (66) transfers rotational motion from the first element (20) to the driven member (14), which can be, for example, a drum (14) of a compactor inside of which the drive mechanism (10) is located. The orientation of the elements of the drive mechanism (10) reduces its width which frees more area inside the space limited drum (14) and eliminates the need to mount components exteriorly to the drum (14) where they can be damaged.
