| 20110281681 | DRIVING MECHANISM FOR A VEHICLE - A driving mechanism has a drive source which is coupled via a clutch to an oil lubricated transmission, and a transmission module which is present parallel to the transmission. The transmission module has a planetary gearing of which a first rotational member is bearing supported on an insert sleeve attached to an operating cylinder for the clutch and is connected to a connecting plate which is attached to a first clutch portion of the clutch. A second rotational member is connected to a connecting gear. A third rotational member is formed by a ring gear which has side guards maintain grease inside the planetary set of gears. | 11-17-2011 |
| 20120172174 | LINEAR ACTUATOR AND METHOD OF OPERATION THEROF - A linear actuator is disclosed. The linear actuator includes a housing, a linear output member, and a rotary lock assembly. The linear output member includes a radial groove and is axially movable from a retracted position within the housing. The rotary lock assembly is constrained from axial motion within the housing and includes a rotor and a lock. The rotor is capable of rotation from a first to a second position. When the linear output member is in the retracted position, the rotor surrounds the radial groove. When the rotor rotates to the first position, the lock engages the radial groove and prevents axial motion of the output member from the retracted position. | 07-05-2012 |
