20140212212 | DRIVE FOR ROTATING DRUM - A drive mechanism for driving a drum, such as a mulcher drum comprises an intermediate shaft coupled to drive the drum by way of a flexible coupling. The flexible coupling may be located on an inside of a hub of the drum. A hydraulic or other motor is coupled to drive the intermediate shaft by a splined coupling. Lubrication of the splined coupling is enhanced by a supply of grease contained in a central passage within the intermediate shaft. The drive mechanism may be direct drive from a hydraulic or other suitable motor. The drive mechanism can be compact and robust against collateral damage resulting from failure of drum support bearings. | 07-31-2014 |
20080210478 | Walking Beam Suspension for Tracked Vehicle - A suspension for a tracked vehicle includes a bogie wheel assembly which has a pair of bogie wheels mounted to a walking beam. The walking beam is coupled to a body of the vehicle by a transversely-extending arm. The arm may be coupled to the body by a spherical bearing which permits angular rotation in at least two directions. The walking beam is connected to the body by shear members arranged in an inverted-V configuration. The shear members may be elastomeric springs. | 09-04-2008 |
