摘要： A drive includes an electric motor disposed in a housing and driving a motor shaft, a Hall effect sensor adjacent to the motor, a power and control assembly, and a pinion gear driven by the motor shaft. A planetary gear reduction assembly is driven by the pinion gear, and an output axle has an axis of rotation that is offset from and parallel to the motor shaft axis of rotation. The reduction drive is substantially bilaterally symmetrical about a plane passing through the motor shaft axis of rotation and the output axle axis of rotation. The power and control assembly comprises a control board oriented perpendicular to a power board and includes a heat dissipation apparatus that applies multi-point, localized, indirect pressure to a plurality of field effect transistors mounted on the power board.

摘要： A combination starter-generator device includes an electric machine and a gear set configured to couple the electric machine and the engine in first and second power flow directions. The gear set is configured to operate in one of at least a first mode, a second mode, or a third mode in the first power flow direction and at least a fourth mode in the second power flow direction. The starter-generator device includes a clutch arrangement with at least one clutch selectively coupled to the gear set to effect the first, second, and third mode in the first power flow direction and the fourth mode in the second power flow direction; and a cam plate configured to shift the at least one clutch between a disengaged position and an engaged position relative to the gear set.

摘要： A method is provided for starting an internal combustion engine with a driveshaft for a motor vehicle. A starting process is carried out, by which the internal combustion engine is started and thereby transferred from a deactivated state into a powered operation, wherein the starting process is carried out by a pinion starter and by a belt starter, by which the driveshaft is driven during the starting process.

摘要： To suppress generation of noise during cranking, a pinion gear is fixed to a drive shaft of a starter starting an internal combustion engine. The pinion gear rotates a ring gear provided to the internal combustion engine by meshing therewith. The pinion gear includes gear teeth and an annular hollow portion located radially inside of the gear teeth. The annular hollow portion accommodates a vibration absorber to absorb vibration generated in the gear tooth.

摘要： A combination starter-generator device is provided for a work vehicle having an engine. The starter-generator device includes an electric machine and a gear set configured to receive rotational input from the electric machine and from the engine and to couple the electric machine and the engine in a first power flow direction and a second power flow direction. The gear set is configured to operate a first, second, or third gear ratio in the first power flow direction and a fourth gear ratio in the second power flow direction. At least one clutch is selectively coupled to the gear set to effect the first, second, and third gear ratios in the first power flow direction and the fourth gear ratio in the second power flow direction. A magnetic cam assembly is configured to shift the at least one clutch from a disengaged position into an engaged position.

摘要： The invention relates to an electromagnetic starter relay having an armature that is axially adjustably arranged, and having a pull-in winding, a hold-in winding and a switching winding. The hold-in winding is connected in series to the pull-in winding, wherein, in a phase stage of the meshing phase only the pull-in winding can be energised and in a different phase stage both the pull-in winding and the hold-in winding can be energised.

摘要： An integrated starter and generator (ISG) system of a vehicle includes: a planetary gear set including a sun gear, a planet carrier, and a ring gear as rotation elements of the planetary gear set; and an integrated starter and generator (ISG) functioning as a motor and a generator, and including a stator and a rotor. The planetary gear set and the ISG are disposed in a crankshaft pulley of an engine such that torque of a crankshaft of the engine is increased and is transmitted to the ISG when generating electricity and torque of the ISG is decreased and is transmitted to the crankshaft of the engine when starting.
