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.
Claims13
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 light gear set associated with a first torque output of the landing gear actuator assembly, the light gear set comprising a light gear wheel having a first width;
- a heavy gear set associated with a second torque output of the landing gear actuator assembly, the second torque output greater than the first torque output;
- a first gear stage connected to the light gear set and the heavy gear set, the first gear stage arranged to increase an initial motor torque of the motor, the first gear stage comprising a light gear wheel having a second width, wherein the first width is greater than the second width;
- and,
- a rotational engagement mechanism arranged to selectably couple the rotational motion of the input shaft to the light gear set and selectably couple the rotational motion of the input shaft to the heavy gear set to rotate the cross-shaft adaptor using the light gear set or the heavy gear set.
