A method for assembling a carrier subassembly for use with a planetary gear train comprises inserting a gear so that the bore of the gear surrounds the bore of the carrier member, and aligning an assembly guide having a bore by engaging a portion of the assembly guide with an alignment feature of the carrier subassembly such that the bore of the assembly guide is aligned with the bore of the carrier member.

The present invention relates to a speed reducer for a vehicle. The speed reducer includes: a gear housing configured to enclose a worm wheel and a worm shaft and including one of a first magnetic member and a second magnetic member, which generate attractive force or repulsive force therebetween as current is applied to a position facing the worm shaft in an axial direction; a first bearing coupled to an end of the worm shaft at an opposite side to a motor shaft-coupling portion; and a moving member coupled, at one side thereof, to an outer race of the first bearing and including, at a remaining side thereof, a remaining one of the first and second magnetic members, so that the moving member is axially moved according to the attractive force or the repulsive force.

A transmission includes an input shaft, configured for receiving torque applied by a motor, a gear system, a differential, at least one output shaft, and a disconnect unit which is switchable between an engaged and a disengaged state. In the engaged state the input shaft is connected to the output shaft via the gear system and the differential for driving the at least one output shaft, and in the disengaged state the at least one output shaft is disconnected from the input shaft. An (electric) vehicle including such a transmission.

A transmission for a power train of a motor vehicle has a first stationary housing part having a first axial contact surface, a second stationary housing part, and a first sealing element on the second stationary housing part, the first sealing element being axially compressible. Additionally, the transmission includes a first planetary gear set including a planet carrier, at least one planet gear, a sun gear, and a ring gear. The planet carrier is fixed relative to one or both of the first stationary housing part and the second stationary housing part. One side of the planet carrier rests against the first axial contact surface, where the first sealing element acts on another side of the planet carrier to axially preload the planet carrier against the first axial contact surface to prevent the planet carrier from tilting relative to a rotation axis of the first planetary gear set.

Methods, apparatus, systems, and articles of manufacture are disclosed. An example apparatus includes a tubular or cylindrical body including a shaft, a shoulder, and a neck, the shaft coupled to the shoulder, the shoulder coupled to the neck, the shoulder having a greater diameter than respective diameters of the shaft and the neck. The example apparatus includes a plug coupled to the shoulder at a first plug edge and coupled to a first fastener at a second plug edge, the first fastener including a hole. The example apparatus includes a second fastener coupled to the first fastener, the second fastener extending through the tubular body, the plug, and the first fastener.

An example adjustable angle bracket is provided. The adjustable angle bracket can include a base having a rectangular shape. The adjustable angle bracket can include a first lug having a top edge and a bottom edge, where the bottom edge of the first lug is coupled to the base, and where the first lug defines a first set of slots. The adjustable angle bracket can include a second lug having a top edge and a bottom edge, where the bottom edge of the second lug is coupled to the base, and where the second lug defines a second set of slots. The first set of slots can define a plurality of angles relative to a direction D orthogonal to the base. The second set of slots can define the plurality of angles relative to the direction D.

An electric drive gearbox assembly with stepped hole positioning is disclosed. Specifically, the electric drive gearbox assembly comprises a first housing, a second housing and a positioning pin. The first housing is provided with a first positioning hole on its connecting surface. The second housing is provided with a second positioning hole corresponding to the first positioning hole. The first housing and the second housing are positioned and connected through the first positioning hole, the second positioning hole and the positioning pin. The first positioning hole and/or the second positioning hole are stepped holes. The stepped hole comprises a guiding section close to an open end of the stepped hole and an engaging section far away from the open end of the stepped hole. An aperture of the guiding section is larger than an aperture of the engaging section. The guiding section is used to guide the positioning pin into the engaging section. In the electric drive gearbox assembly, the first housing can be pre-positioned when assembled with the second housing, and the first housing can be radially adjusted relative to the second housing during pre-positioning, so as to facilitate the positioning and assembly of the first housing and the second housing, and promote automated and batch assembly of the electric drive assembly.

The utility model discloses a stepped hole positioning electric drive gearbox assembly. The stepped hole positioning electric drive gearbox assembly specifically comprises a first shell, a second shell and a positioning pin. A first positioning hole is formed in the connecting surface of the first shell, a second positioning hole corresponding to the first positioning hole is formed in the second shell, and the first shell and the second shell are in positioning connection through the first positioning hole, the second positioning hole and a positioning pin; the first positioning hole and/or the second positioning hole are/is stepped holes, each stepped hole comprises a guiding section close to the hole opening and a matching section away from the hole opening, the hole diameter of the guiding section is larger than that of the matching section, and the guiding section is used for guiding the positioning pin to enter the matching section. In the electric drive gearbox assembly, the first shell can be pre-positioned when being assembled with the second shell, and the first shell can be radially adjusted relative to the second shell during pre-positioning, so that the first shell and the second shell can be conveniently positioned and assembled, and the electric drive gearbox assembly can be automatically and massively assembled.
