Abstract
A landing gear system including a landing gear actuator assembly arranged to selectably provide an increased torque output to a cross-shaft adaptor rotationally coupled to a cross-shaft of a trailer landing gear assembly. A rotational engagement mechanism is arranged to, in response to a remote signal, shift a rotational engagement mechanism to selectably couple the cross-shaft adaptor with a light gear set or selectably couple the cross-shaft adaptor with a heavy gear set. The landing gear actuator includes a slip-clutch assembly to dampen, reduce, or eliminate rotational shock caused when retracting or extending the legs of the landing gear system.
Claims19
A landing gear actuator assembly, comprising:
- an input shaft arranged to receive rotational motion generated by a motor;
- a cross-shaft adaptor arranged to couple the landing gear actuator assembly to a cross-shaft of a trailer landing gear assembly;
- a gear set associated with a first torque output of the landing gear actuator assembly;
- and
- a rotational engagement mechanism arranged to selectably couple the rotational motion of the input shaft to the gear set to rotate the cross-shaft adaptor using the gear set;
- wherein the rotational engagement mechanism is arranged to translate between a first position and a second position, wherein the first position is associated with a transfer of the first torque output from the gear set to the rotational engagement mechanism and the second position is associated with a neutral mode.
A landing gear system, comprising:
- a first landing gear leg rotationally engaged with a cross-shaft of a trailer landing gear assembly;
- and
- a landing gear actuator assembly comprising:
- an input shaft arranged to receive rotational motion generated by a motor;
- a cross-shaft adaptor arranged to couple the landing gear actuator assembly to a cross-shaft of a trailer landing gear assembly;
- a gear set associated with a first torque output of the landing gear actuator assembly;
- and,
- a rotational engagement mechanism arranged to selectably couple the rotational motion of the input shaft to the gear set to rotate the cross-shaft adaptor;
- wherein the rotational engagement mechanism is arranged to translate between a first position and a second position, wherein the first position is associated with a transfer of the first torque output from the gear set to the rotational engagement mechanism and the second position is associated with a neutral mode.
