A mechanical unlocking mechanism for electronic parking is provided, which comprises a parking cam assembly, a pawl assembly, a pull rod assembly and a parking gear; the parking cam assembly comprises a parking guide shaft and a parking cam, the parking cam is sleeved on the parking guide shaft, at least a first convex part and a second convex part are provided at two sides of the parking cam, and a connecting part is provided on the second convex part; the pull rod assembly is connected with the parking cam via the connecting part, and the pull rod assembly pulls the second convex part to drive the parking cam to rotate; the parking gear can be fixed or rotatable according to the pawl assembly being in a first position where the parking gear parks in or a second position where the parking gear parks out as the parking cam rotates.

Mechanical unlocking mechanism for electronic parking

A mechanical unlocking mechanism for electronic parking is provided, which comprises a parking cam assembly, a pawl assembly, a parking gear, a pull cord assembly and an actuating assembly, wherein the pull cord assembly comprises a pull wire and a guide shaft screw, each of two ends of the pull wire is provided with a pull wire ball head rod, the pull wire ball head rod is connected with an end of the pull wire and is connected with an end hole of the parking guide shaft or the actuating assembly via the guide shaft screw sleeved on the pull wire. The mechanical unlocking mechanism according to the present disclosure provides an emergent mechanical unlocking function when the parking motor is powered off, and the driver can perform manual mechanical unlocking in the cab without getting off the vehicle, so it has high safety and good operation comfort.

A longitudinal multi-shift electrically driving power assembly, wherein the longitudinal multi-shift electrically driving power assembly includes an electric motor and a plurality of sets of gearboxes, each of the gearboxes is a single-shift reduction gearbox or a multi-shift reduction gearbox, the gearboxes are connected in series to form a gearbox assembly, and an output shaft of the electric motor and an input shaft of the gearbox assembly are integrally manufactured. The power assembly employs the plurality of sets of gearboxes that are connected in series, which improves the performance of the power assembly without adding a power source.

Electric drive powertrain having vertically-positioned multi-stage gearboxes

The present disclosure discloses an oil-lubrication mechanism for a fore bearing of a water-cooled electric motor and an electric-motor driving assembly, which solves the problems of conventional grease lubrication of the fore bearing of water-cooled electric motors such as serious bearing heat generation and bearing failure and low life caused by easy outflowing of the grease. The oil-lubrication mechanism includes a gear-splashing oil-storage structure provided in a gearbox or a reduction gearbox, and a bearing-baffle oil-storage structure provided at a front end of the water-cooled electric motor; and a gear in the gearbox or the reduction gearbox in operation throws a lubricating oil into the gear-splashing oil-storage structure, and the lubricating oil is delivered via the oil conduit into the bearing-baffle oil-storage structure, thereby lubricating the fore bearing of the water-cooled electric motor, and subsequently the lubricating oil flows back into the gearbox or the reduction gearbox via the oil return tube. In the present disclosure, the lubricating oil that splashes inside the gearbox or the reduction gearbox is introduced into the fore bearing of the water-cooled electric motor, which enables the fore bearing of the water-cooled electric motor to be lubricated by the oil, thereby reducing the heat generation of the fore bearing of the water-cooled electric motor, and improving the life of the fore bearing and the reliability of the electric motor.
