Abstract

A landing gear apparatus (10) for supporting the trailer portion of a tractor-trailer (22) is provided. The landing gear apparatus (10) includes a drive leg (24), an actuation mechanism (12), a drive mechanism (14), a motor (16), and a controller (18). The drive leg (24) has a first member (30) slidably received within a second member (32), The actuation mechanism (12) is engaged with the first member (30) and operable to actuate the first member (30) relative to the second member (32) between a retracted position and an extended position. The drive mechanism (14) is disposed within the drive leg (24). The drive mechanism (14) includes an output shaft (50), an input shaft (48), an intermediate shaft (52), a first gear (54), a second gear (50), and a pair of intermediate shaft gears (58, 60). The first gear (54) is mounted on the output shaft (50) and engaged with the actuation mechanism (12). The second gear (50) is mounted on the input shaft (48). The intermediate shaft gears (58, 60) are mounted on the intermediate shaft (52). The input shaft (48) is selectively axially movable between a first position where the first gear (54) and second gear (50) are engaged and in contact with one another, and a second position where the first gear (54) and the second gear (50) are not in contact with one another. The motor (16) is coupled to the intermediate shaft (52) of the drive mechanism (14). The controller (18) selectively controls the motor (16) to operate the drive mechanism (14) and the actuation mechanism (12) to actuate the first member (30) and second member (32) between the retracted position and the extended position.
