A motor oil pump assembly includes: a motor component; an oil pump component, where the oil pump component is supported on an end cover of the motor component; an inner sound insulation enclosure, where the inner sound insulation enclosure encloses the oil pump component, and the inner sound insulation enclosure and the oil pump component define an inner sound insulation cavity filled with low-pressure oil; and a pre-tightening buffering component, where the pre-tightening buffering component is pressed between an upper end cover of the oil pump component and the inner sound insulation enclosure, and the pre-tightening buffering component is in communication with a high-pressure cavity of the oil pump component.

Motor oil pump assembly, steering system, and vehicle

A hydraulic system of an electric vehicle may comprise: an oil container; a first and a second clutch driving circuits connected in parallel; an internal pump driven by a driving system of the electric vehicle; a first check valve connected in series at an outlet side of the internal pump; an external pump driven by an external pump motor; and a second check valve connected in series at an outlet side of the external pump. The first check valve and the internal pump connected in series and the second check valve and the external pump connected in series are connected in parallel between the oil container and the first and second clutch driving circuits.

Hydraulic system, driving system and electric vehicle

A drive system of an electric vehicle includes a drive motor, a transmission and a hydraulic system. The transmission has an input shaft, a countershaft, an output shaft, a first transmission unit placed between the countershaft and the output shaft, a first clutch, a second transmission unit placed between the countershaft and the input shaft, and a second clutch. The drive motor is attached to the input shaft, which is attached to the countershaft to provide power of the drive motor to the countershaft; the first clutch is configured for linking or cutting off the power transmission between the countershaft and the first transmission unit; and the second clutch is configured for linking or cutting off the power transmission between the countershaft and the second transmission unit. The first transmission unit has a first transmission ratio greater than a second transmission ratio of the second transmission unit.

Drive system of an electric vehicle

A hybrid power driving system for a vehicle comprises an internal-combustion engine, a first electric motor, a second electric motor, a planetary coupling mechanism, a speed-reduction mechanism and a differential mechanism. An output shaft of the internal-combustion engine is connected with an input shaft of the first electric motor, and an output shaft of the first electric motor is connected with an output shaft of the second electric motor via a first clutch. The output shaft of the second electric motor is connected with one of a sun gear and a ring gear of the planetary coupling mechanism at a position of the output shaft along its axial direction. And the output shaft of the second electric motor is connected with the other one of a sun gear and a ring gear at another position of the output shaft along the axial direction via a second clutch.

Hybrid power driving system and gear position operation method thereof

A hybrid vehicle includes a battery system, an internal combustion engine, a first motor/generator, a second motor/generator, and an engageable clutch assembly. The engageable clutch assembly is disposed between the internal combustion engine and the first motor/generator. When engaged, the engageable clutch assembly couples the rotor spindle of the second motor/generator with the hollow rotor shaft of the first motor/generator. The engageable clutch assembly may also operate in a first mechanical mode that selectively engages and disengages the internal combustion engine from the second motor/generator, or operate in a second mechanical mode that dampens shock between the internal combustion engine and the first motor/generator when the international combustion engine operates at a rotational speed that is different than a rotational of the first motor/generator.

Hybrid vehicle having engageable clutch assembly coupled between engine and traction motor

A hybrid vehicle has a power system with a torsional coupling. The power system includes a battery system for receiving, storing and providing electrical power, an internal combustion engine configured to provide rotational power through a flywheel, a first motor-generator, a second motor-generator, a control system, and a torsional coupling. The torsional coupling may absorb rotational shock caused by angular or rotational speed differences between the engine and the first motor-generator. The torsional coupling includes a driven plate assembly, a cover assembly and an interconnecting plate assembly. The interconnecting plate assembly may include a plurality of shock absorbing elements that absorb shock and vibration between the engine and the motor-generator.

Hybrid vehicle having torsional coupling between engine assembly and motor-generator

A hybrid vehicle includes two front wheels, two rear wheels, an internal combustion engine, a first motor/generator, and a second motor/generator. The first motor/generator may be rotatably coupled to the internal combustion engine, and the second motor/generator may be rotatably coupled to at least one wheel of the hybrid vehicle. The first motor/generator, the second motor/generator and a gear transmission are housed within the engine compartment and are located between two front wheels and arranged in a substantially linear manner. The first motor/generator, the second motor/generator, and the gear transmission are located substantially above a centerline of the front wheels of the vehicle.
