摘要： A variable transmission may include a segmented pulley and a nested pulley located at least partially within the segmented pulley. The spacing between the components of the first segmented pulley may be varied to alter the transmission ratio of the variable transmission by altering the effective diameter of the segmented pulley. The nested pulley may also be a segmented pulley. In some embodiments, one of the pulleys may be rotationally fixed, and the variable transmission may comprise a compact infinitely variable transmission. The eccentricity of the compact infinitely variable transmission may be significantly less than the eccentricity of other infinitely variable transmission designs. In other embodiments, a nested pulley structure may be used to provide a compact continuously variable transmission.

摘要： A transmission speed control system for a walk-behind lawn mower includes a transmission, a transmission positioning assembly, and an electronic control unit. The transmission is tiltable about and operably engaged with a drive axle shaft. The transmission positioning assembly tilts the transmission between first and second angular positions. A belt tension between a drive belt and a transmission pulley of the transmission continuously increases from a minimum belt tension when the transmission is in the first angular position to a maximum belt tension when the transmission is in the second angular position. The rotational drive force exerted on the drive axle shaft by the transmission and a resulting driving speed of the lawn mower vary proportionally with the belt tension. The electronic control unit controls the transmission positioning assembly to tilt the transmission based on target and detected driving speeds.

摘要： A belt drive system for a vehicle, such as a combine harvester. The belt drive system uses a driven pulley which is selectively engageable with a driven shaft to supply rotation to the shaft. The pulley is mounted on a fixed, i.e. non-rotating, housing using suitable bearings, such that the bearings of the pulley continue to rotate and are dynamically loaded for all rotation conditions of the driven pulley, i.e. whether the pulley is engaged with the shaft or not. This prevents damage to the bearings due to false brinelling.

摘要： A belt pulley decoupler is provided for transmitting drive torque from belts of an auxiliary unit belt drive to the shaft of one of the auxiliary units, including: a belt pulley, a hub secured to the shaft, and a series circuit arranged in the drive torque flow between the belt pulley and the hub and including a decoupler spring and a wrap-around band that extends in the direction of the rotational axis of the belt pulley decoupler and is arranged radially between the belt pulley and the decoupler spring. Both ends of the wrap-around band open out radially when the drive torque is transmitted, the first end of the wrap-around band is braced against the inner surface of a first sleeve rotationally fixed in the belt pulley, and the second end of the wrap-around band is braced against the inner surface of a second sleeve rotationally mounted in the first sleeve.

摘要： A continuously variable transmission (CVT) system, which turns the rear wheels of a lawn mower or similar vehicle at different speeds in a coordinated method with the front steering wheels in order to achieve the best turning radius (including a tight or zero turn radius, if desired) under most conditions. The system comprises two stages: the first stage comprising a Fixed Center Distance CVT pulley system, and the second stage comprising dual CVTs (e.g., left and right) that input into dual gear reducers (left and right), which are mechanically connected to the rear wheels. The second stage dual CVTs (left and right) are synchronized with the steering wheel, thus achieving different rear wheel speeds and/or directions based on the steering wheel position.

摘要： Disclosed here are inventive systems and methods for a powertrain of an electric vehicle (EV). In some embodiments, said powertrain includes a continuously variable transmission (CVT) coupled to an electric drive motor, wherein a control system is configured to control the CVT and/or the drive motor to optimize various efficiencies associated with the EV and/or its subsystems. In one specific embodiment, the control system is configured to operate the EV in an economy mode. Operating in said mode, the control system simultaneously manages the CVT and the drive motor to optimize the range of the EV. The control system can be configured to manage the current provided to the drive motor, as well as adjust a transmission speed ratio of the CVT. Other modes of operation are also disclosed. The control system can be configured to manage the power to the drive motor and adjust the transmission speed ratio of the CVT taking into account battery voltage, throttle position, and transmission speed ratio, for example.
