摘要： An electric brake assembly for a planetary reduction drive includes a first housing defining a brake housing compartment, first and second stators disposed within the brake housing compartment, and a rotor disposed within the brake housing compartment between the first and second stators. The rotor has a spline engaging an output shaft of a motor. The electric brake assembly also includes a brake end cap coupled to the first housing and defining a cylindrical volume, a plug movably disposed in the cylindrical volume of the brake end cap, a spring disposed within the cylindrical volume of the brake end cap and compressed by the plug to apply a spring biasing force for pressing the second stator against the rotor, and an electric brake coil positioned adjacent to the second stator to electromagnetically pull the second stator away from the rotor when energized.

摘要： A control assembly for use with a vehicle having a pivot arm for controlling output of the vehicle includes a bracket, a yoke attached to the pivot arm, and a shaft engaged to the yoke and extending into the bracket. The pivot arm is rotatable about a first axis of rotation between a neutral position and a plurality of forward positions and a plurality of reverse positions. When in the neutral position, the pivot arm may also rotate about a second axis of rotation between an operative position and a stopped position, and a switch may be engaged when the pivot arm is rotated to the stopped position. A return to neutral assembly may provide a return force to the pivot arm when it is rotated about the first axis of rotation away from the neutral position.

摘要： A power distribution assembly integrated into the lower engine housing of an internal combustion engine, the assembly having a drive train with a T-box output configuration and power take off driven by the crankshaft of the engine. The drive train may power the input shafts of a pair of independent, variable drive transmissions. In one embodiment, a single actuator engages a manual clutch/brake mechanism that controls the output shaft of the power take off. In other embodiments, an electric clutch generates magnetic actuation to control of the power take off mechanism. In further embodiments, a hydraulic clutch/brake assembly allows control of the power take off, and an additional hydraulic clutch assembly may be used to control the outputs of the T-box.

摘要： A valve plate or end cap includes a running surface having a pair of arcuate kidney ports formed thereon. The running surface also includes a plurality of pressure gradient grooves formed on the running surface, each pressure gradient groove having a proximal end adjacent to a respective one of the ends of one of the kidney ports and a distal end. The distal end of one of the pressure gradient grooves associated with one kidney port may overlap the distal end of a pressure gradient groove associated with the other kidney port. The distal end of at least one of the pressure gradient grooves is located outside the circumference of a pitch circle that passes through the center of each kidney port. The distal end of at least one of the other pressure gradient grooves is located inside the pitch circle circumference.

摘要： A variable speed drive includes a transmission in a housing with a rotatable control shaft for moving the transmission between neutral and drive positions. A rotary damper is engaged to an external control arm which rotates the control shaft. A return to neutral mechanism is engaged to the control shaft to return the transmission to neutral. The external damper may be a viscous fluid damper having a plate, a rotor element with a first set of concentric projections, and a stator element with a second set of concentric projections that mesh with the first set of concentric projections. A method is provided for assembling a damper subassembly and a return arm subassembly, and connecting the damper subassembly to the housing, connecting the control arm to the control shaft and connecting the return arm subassembly to the control shaft for ease of assembly.

摘要： A reduction drive assembly includes a planetary gear assembly. The planetary gear assembly includes a first gear carrier that includes a first plate and projections extending therefrom. The first plate defines first support openings. The planetary gear assembly includes a second gear carrier that defines second support openings and joint openings. The joint openings receive the projections to couple the first and second gear carriers. The planetary gear assembly includes a sun gear coupled to an output shaft and disposed between the first and second gear carriers. The planetary gear assembly includes planet gears disposed around the sun gear between the first and second gear carriers. Each of the planet gears has a carrier pin. Each carrier pin is received by one of the first support openings and one of the second support openings to retain the planet gears between the first and second gear carriers.

摘要： A performance learning system and method is provided for a utility vehicle. The performance learning system includes a propulsion system, a plurality of sensors disposed on the vehicle and capable of acquiring operational data associated with the vehicle, a processor, and a memory configured to store historical operational data. The processor can be configured to receive the operational data from the sensors, generate and transmit a command to control the propulsion system based on the operational data and the historical operational data, and update the historical operational data based on the operational data. The operational data may include characteristics associated with one or more of an operator of the vehicle or an operating environment of the vehicle. The systems and methods may optimize the performance of the utility vehicle for particular environments and conditions in which the utility vehicle is being operated and increase operator satisfaction.
