摘要： The present invention relates to a method to control a hybrid powertrain, comprising a combustion engine, an electric machine, a gearbox with input shaft and output shaft, wherein the combustion engine and the electric machine are connected to the input shaft. The method comprises the following steps: a) disconnecting the combustion engine from the input shaft with a coupling device, b) engaging a starting gear in the gearbox, which starting gear is higher than the gear at which the combustion engine's torque at idling speed is able to operate the input shaft, c) generating a torque in the input shaft with the electric machine, d) accelerating the electric machine, and e) connecting the combustion engine to the input shaft with the coupling device when the electric machine has reached substantially the same rotational speed as the combustion engine. The invention also relates to a hybrid powertrain and a vehicle.

摘要： A belt pulley decoupler for the drive torque transmission between a belt of a starter-generator belt drive and the starter generator is provided. A hub is fastened on a generator shaft of the starter generator. A decoupler spring is configured to transmit drive torque of the belt from the belt pulley to the hub when the starter generator is powered. A rotary stop has a stop part on the belt pulley and a stop part on the hub. The rotary stop is configured to transmit drive torque of the generator shaft from the hub to the belt pulley when the starter generator is driving the belt. The decoupler spring is loaded in both torque directions and participates in the transmission of the drive torque from the hub to the belt pulley when the starter generator is driving the belt.

摘要： The invention discloses a lower pair arc stop-block overrunning clutch comprising an outer rotating element, an inner rotating element, a friction block assembly, a wedge assembly, a first propeller assembly, a first elastic element and a synchronized push-block assembly, wherein a plurality of friction blocks of the friction block assembly are connected end to end and arranged between a first rotating ring and a second rotating ring; an drive element drives the first propeller assembly to press the synchronized push-block assembly to achieve synchronization of the friction block assembly; the first propeller assembly strikes the friction block assembly and is relatively stationary to push the friction block assembly for generating reverse rotation relative to a driven element; the wedge assembly is wedged to generate a radial pressure on the friction block assembly so that the friction block assembly can achieve lower pair arc stop, thereby achieving the transfer of torque.

摘要： An engine assembly may include an internal combustion engine and an expander couplable to the internal combustion engine in a force transmitting manner. The engine assembly may also include a pulley mounted rotatably on a shaft of the expander. The pulley may be coupled to the internal combustion engine in a force-transmitting manner via a belt drive. The engine assembly may further include a first driver plate connected non-rotatably to the pulley and a second driver plate arranged adjacent thereto and connected non-rotatably to the shaft. The engine assembly may additionally include a clutch device including at least one actuating device and a coupling wheel. The coupling wheel may contact the first driver plate and the second driver plate when the clutch device is closed such that the pulley is connected with the shaft of the expander in a driving manner.

摘要： A starter for an internal combustion engine may include a support, an electric motor for driving a pinion in rotation, and a solenoid drive configured to axial adjust the pinion between an active position and a passive position. The solenoid drive may include a ferromagnetic plunger stop, a plunger axially adjustable, and a cylindrical coil arrangement surrounding a cylindrical coil interior. The plunger stop may include a cylindrical section projecting into the coil interior. The plunger may be arranged axially opposite the cylindrical section and, when the pinion is in the active position, protruding axially into the coil interior. When the pinion is in the passive position, a face-side plunger end may be arranged axially in a proximal end portion. The cylindrical section may extend into the coil interior such that a face end is closer to the proximal end portion than to a distal end portion.
