Drive device

摘要

A clutch for driving a pair of output axles for a drive mechanism includes a driven clutch bevel gear mounted on a clutch shaft. A pair of clutch rings is disposed on opposite sides of the bevel gear and slidable along a clutch shaft, to selectively engage a pair of driven gears. A pair of clutch arms engages the clutch rings for moving each clutch ring between its engaged and disengaged positions, and a plurality of springs disposed along the clutch shaft biases the clutch rings to their respective engaged positions. The drive mechanism may include a mounting member having a running surface for a hydraulic motor, a pair of arms on opposite sides and extending away from the running surface, wherein the clutch shaft extends between and is supported by the pair of arms.

主权项

1. A drive apparatus, comprising
a mounting member disposed in a housing and having a first side and a second side opposite to the first side, a motor running surface on the first side and a pair of arms located on opposite sides of the mounting member and extending away from the second side; a hydraulic motor rotatably disposed on the motor running surface and driving a motor shaft, the motor shaft having a proximal end disposed on the first side of the mounting member and extending through the hydraulic motor and the mounting member whereby a distal end of the motor shaft is located on the second side of the mounting member, a first gear on the distal end of the motor shaft between the pair of arms; a clutch support shaft extending between and supported by the pair of arms; a clutch gear rotatably disposed on the clutch support shaft and having a first end and a second end, the clutch gear comprising a bevel gear portion driven by the first gear; a pair of clutch rings driven by the clutch gear and slidably disposed on opposite ends of the clutch support shaft and a pair of second gears disposed on opposite ends of the clutch support shaft, wherein each clutch ring is slidable between a first, engaged position where it engages and drives one of the pair of second gears, and a second, disengaged position where it does not drive the said one of the pair of second gears; and a first clutch arm and a second clutch arm, the first clutch arm engaged to one of the pair of clutch rings to move said one of the pair of clutch rings from its respective first, engaged position to its second, disengaged position, and the second clutch arm engaged to the other of the pair of clutch rings to move said other of the pair of clutch rings from its first, engaged position to its second, disengaged position, wherein the first clutch arm and the second clutch arm may be operated independently of each other.
