A keyless rotation transfer unit may include a spline forming a pulley coupling force between an inner circumference of a shaft hole of a pulley and an outer circumference of a keyless shaft end forming one end of a shaft, with the keyless shaft end inserted into the shaft hole, and a flange nut screw-fastened to the keyless shaft end coming out of the shaft hole and forming a screw fastening force to press one surface of the pulley. In particular, the screw fastening force forms a shaft fastening force that causes a bearing to pressurize the other surface of the pulley, the bearing is coupled to the keyless shaft end and located at the rear of the pulley, and the flange nut forms a pulley holding force using the screw fastening force and the shaft fastening force.

An accessory drive, including a planetary gear set with a plurality of components arranged to be concentrically disposed around a crankshaft of an internal combustion engine. The plurality of components includes: a sun gear; a planet carrier; a ring gear; and a planet gear meshed with the sun gear and the ring gear. A first component of the planetary gear set: is arranged to non-rotatably connect to a rotor of an electric motor/generator; and is arranged to connect to a power transfer component for least one accessory. A second component of the planetary gear set is arranged to non-rotatably connect to the crankshaft. For a starting mode of the accessory drive, the electric motor/generator is arranged to: rotate the first component of the planetary gear set; and rotate the second component of the planetary gear set with respect to the first component of the planetary gear set.

Various embodiments include an isolation ring for isolating the end windings of a stator of an electrical machine, the isolation ring comprising: a protrusion with a conductor guide for receiving a conductor, wherein the protrusion comprises: a pressing flap with an inner guiding surface; and a pocket with a temperature sensor arranged in the pocket. The inner guiding surface faces the pocket. The pressing flap and the pocket are arranged so an end of the conductor inserted in the conductor guide is guided between the inner guiding surface and the temperature sensor, and the end is pressed against and/or guided to the temperature sensor.

A work machine comprises a work unit that performs work on a travel path, an internal combustion engine configured to generate power for driving the work unit, a traveling unit including a front wheel and a rear wheel, an electric motor configured to generate power for driving a first wheel of the front wheel and the rear wheel, and a first clutch for switching between transmission and discontinuation of the power from the internal combustion engine to a second wheel of the front wheel and the rear wheel.

A vehicle includes an engine, a motor, and a controller. The engine and motor are each configured to deliver torque to a torque converter impeller. The controller is programmed to, responsive to a demanded impeller torque exceeding an upper motor torque threshold while the motor alone is delivering torque to the impeller, increase motor torque to a value that is less than the threshold and that depends on a torque converter bypass clutch torque capacity and a torque converter turbine speed.
