Abstract
A variable speed transmission disposed in a housing includes a transmission input shaft and a transmission output shaft. A power take off is disposed in the housing and includes a power take off output shaft and a clutch/brake mechanism having a clutch input hub engaged to and driven by the transmission input shaft, a cage engaged to the clutch input hub, a brake stator and a brake rotor and carrier being selectively engageable with the cage and alternately selectively engageable with the brake stator. An output hub is rotatably driven by the brake rotor; and a biasing member is disposed between the cage and the brake rotor to bias the brake rotor to engagement with the brake stator.
Claims22
A drive apparatus, comprising:
- a variable speed transmission disposed in a housing and having a transmission input shaft and a transmission output shaft;
- a first clutch assembly engaged to the transmission output shaft, wherein the first clutch assembly is also engaged to and selectively drives a first axle shaft;
- a second clutch assembly engaged to the transmission output shaft, wherein the second clutch assembly is also engaged to and selectively drives a second axle shaft;
- a power take off comprising a power take off output shaft and a clutch/brake mechanism, the clutch/brake mechanism comprising:
- a cage engaged to a clutch input hub;
- a brake stator engaged to the housing;
- a carrier selectively engageable with the cage and alternately selectively engageable with the brake stator;
- an output hub engaged to the carrier;
- and
- an actuation fork moveable between a first, engaged position where the carrier is engaged to the cage to cause rotational force to be transmitted from the clutch input hub to the output hub, and a second, disengaged position.
A drive apparatus, comprising:
- a variable speed transmission disposed in a housing and having a transmission input shaft and driving a transmission output shaft;
- a power take off comprising a power take off output shaft and a clutch/brake mechanism, the clutch/brake mechanism comprising:
- a clutch input hub engaged to and driven by the transmission input shaft;
- a cage engaged to the clutch input hub;
- a brake stator engaged to the housing;
- a brake rotor assembly comprising a brake rotor and a carrier, wherein the brake rotor is directly engaged to and rotates with the carrier through a toothed engagement, the brake rotor assembly being selectively engageable with the cage and alternately selectively engageable with the brake stator;
- an output hub rotatably driven by the brake rotor;
- and
- a biasing member disposed between the cage and the brake rotor to bias the brake rotor to engagement with the brake stator.
A drive apparatus, comprising:
- a variable speed transmission disposed in a housing and comprising a hydraulic pump driven by a pump shaft;
- an input shaft extending into the housing and engaged to and driving the pump shaft;
- a power take off comprising a power take off output shaft and a clutch/brake mechanism, the clutch/brake mechanism comprising a clutch input hub engaged to and driven by the pump shaft and an output hub driving the power take off output shaft, wherein the input shaft is at least partially disposed in the housing and at least a portion of the input shaft is located between the hydraulic pump and the clutch/brake mechanism.
A drive apparatus, comprising:
- a variable speed transmission disposed in a housing and having an input shaft having a first axis of rotation and driving a transmission output shaft;
- a power take off comprising a power take off output shaft and a clutch/brake mechanism, wherein the power take off output shaft has an axis of rotation that is collinear with the first axis of rotation, and the clutch/brake mechanism comprises:
- a clutch input hub engaged to and driven by the input shaft;
- a cage engaged to the clutch input hub;
- a brake stator engaged to the housing;
- a brake rotor assembly comprising a brake rotor, the brake rotor assembly being selectively engageable with the cage and alternately selectively engageable with the brake stator;
- an output hub rotatably driven by the brake rotor;
- and
- a biasing member disposed between the cage and the brake rotor to bias the brake rotor to engagement with the brake stator.
