摘要： An electric vehicle transmission mechanism which is applied to drive a chain wheel of an electric vehicle is provided. The electric vehicle transmission mechanism includes a transmission shaft, an output shaft, a lower bearing and an upper bearing. The transmission shaft is connected to the chain wheel and has a transmission axial direction, and the transmission shaft includes a transmission portion. The output shaft includes an output portion engaged with the transmission portion, and the output shaft has an output axial direction substantially perpendicular to the transmission axial direction. The lower bearing is sleeved on the output shaft. The upper bearing is sleeved on the output shaft and located between the lower bearing and the output portion.

摘要： A power tool includes a motor disposed in a motor housing, a handle extending downward from the motor housing, a main switch provided on the handle and configured to switch the motor ON and OFF, and a state-changing operation part located on a lower portion of the motor housing or on an upper-end portion of the handle. The state-changing operation part is located upward of the main switch and is configured to effect a change of a rotational state of the motor, other than a direction of rotation of the motor, or an illumination level of a light.

摘要： A transmission arrangement for a motor vehicle includes a first planetary gear set and a second planetary gear set. A first dog element is axially between the second and third dog elements and is rotationally fixed to the first ring gear. A first shift element shiftable to rotationally fix the first dog element to one or both of the first sun gear and the first planet gear carrier and a second shift element shiftable to rotationally fix the first shift element to one of the rotary elements of the second planetary gear set. A second dog element is rotationally fixed to the second sun gear and is rotationally fixable by the first shift element to one or both of the first sun gear and the first planet gear carrier. A third dog element is rotationally fixed to the second sun gear and connectable to the first ring gear by the second shift element.

摘要： A two-speed transmission alternately establishes two speed ratios between a primary drive pulley and one or more accessories pulleys of an accessory drive system. The two-speed transmission includes concentric input and output shafts fixed to input and output pulleys respectively. When an actuator is disengaged, a one-way clutch transfers power between the input shaft and the output shaft. The input shaft is fixed to the planet carrier of a planetary gear set and the output shaft is fixed to the sun gear of the planetary gear set. When the actuator is engaged, the ring gear of the planetary gear set is held establishing an overdrive speed relationship between the input pulley and the output pulley.

摘要： A drive system includes a planetary gear set having first and second rotatable input members connected in driven relation with respective first and second power sources, and a rotatable output member connected in driving relation with a working piece, the first and second rotatable input members being connected in differentially rotatable communication with the output member. The input members are operable to vary the rotation and direction of the output member and the connected working piece. In an aspect, the output member is rotatable about an axis for driving the working piece, and the first and second input members are also rotatable about the axis. In a further aspect, the first and second input members include coupling regions for coupling the first and second power sources on-axis with the drive system. In a further aspect, the second power source is a hydraulic input motor concentric with the first input member.

摘要： An electric drive for a motor vehicle includes a housing, an output shaft, an electric engine, which has a stator and a rotor rotatable relative to the stator, a planetary gear set arranged in the housing, which has a sun gear, a ring gear and a planetary carrier, which is non-rotatably connected to the output shaft, having a first switching element, by means of which the ring gear can be non-rotatably coupled to the rotor, and a second switching element, by means of which the ring gear can be non-rotatably coupled to the housing. The first switching element and the second switching element are coupled to each other via a first coupling element and thereby can be operated together by a single first actuator common to the first switching element and the second switching element.

摘要： A front end accessory drive system is disclosed. The system includes a hub configured to drivingly engage with a crankshaft and a gear transmission system. A one-way clutch includes a first bearing ring connected to an end of a plurality of planet pins of the gear transmission system, and a second bearing ring connected to a sun gear of the gear transmission system. A pump configured to direct hydraulic fluid through a hydraulic fluid circuit. A clutch pack is in fluid connection with the hydraulic fluid circuit. The clutch pack includes at least one clutch plate supported by the gear transmission system, such that a portion of the gear transmission system is grounded via frictional engagement of the at least one clutch plate in an actuated state of the clutch pack.
