A gear unit includes a shaft, in particular an input shaft, a flange part and a housing part. The input shaft is supported by bearings in the housing part, and a fan is connected to the shaft in a torsion-proof manner. The housing part includes cooling fins, in particular cooling fins that extend in the axial direction, i.e. in the axis direction of the shaft, the cooling fins have an offset and/or stepped configuration, and the flange part surrounds the offset or stepped region of the cooling fins, in particular in the manner of a housing.

There is provided a work vehicle including a partition wall to keep partition between a first space zone as part of an internal space of the transmission case in which a differential mechanism is located and a second space zone as part of the internal space which is adjacent to the first space zone. An upper space is disposed above the partition wall and configured to allow lubricating oil scooped up from the first space zone by a ring gear to flow in the second space zone. A flow-out path is disposed below the upper space and configured to allow the lubricating oil to flow out of the second space zone to the first space zone.

A transmission includes a housing part and a cover. A bead which borders a surface region of the housing part is molded onto the housing part, and a precision-machined surface is formed on the bead. The cover is connected to the housing part, and a seal, e.g., a flat seal, which is arranged on the surface, is arranged between the cover and the surface. A spatial region is delimited by the cover and the surface region and the bead. A bearing cover is arranged in the spatial region, and the bearing cover is connected to the housing part and rests against another surface which is formed on an additional bead. The other surface has an interrupted configuration.

There is provided a work vehicle including an oil outlet port and a partition part. The oil outlet port opens to a bottom portion in one end side of a transmission case in a vehicle body front-back direction and a vehicle body left-right direction. The oil outlet port takes out a lubricating oil from an interior of the transmission case. The partition part divided an internal space of the transmission case into a first space zone along a sidewall portion of the transmission case, and a second space zone other than the first space zone. The partition part brings the first space zone into a sealed state.

A housing for a motor-transmission unit with at least two housing sections which have in each case at least one accommodation segment for receiving a motor and an internally-toothed, internal ring gear segment for receiving a gear of a planetary gear unit, wherein the housing sections can be or are connected with each other and wherein, in the assembled state, the accommodation segments of the housing sections together form at least one accommodation compartment for holding the motor, and the internal ring gear segments of the housing sections together form an internal ring gear for mating with a gear on the planetary gear unit.

This invention is directed toward a powertrain for a road cleaning vehicle. In particular, the powertrain includes a hydrostatic gearbox (34) having a casing (50) for directing power from a primary gearbox to a drivetrain and/or one or more road cleaning tools. The casing (50) comprises first and second sections (51, 52) and a plurality of passageways (107, 107) defined by the edges of both the first and second sections (51, 52). An input shaft is provided having an integral gear extending orthogonally therefrom and having an outer portion extending outside of the internal volume of the casing.

A dual-independent powertrain for a vehicle includes a transmission enclosure that houses a first transmission and a second transmission that are mechanically decoupled from each other. The enclosure includes a central frame, a first enclosure cover that interfaces with the central frame to collectively define a first transmission region on a first side of the central frame, and a second enclosure cover that interfaces with the central frame to collectively define a second transmission region on a second side of the central frame. The first transmission is housed within the first transmission region, and the second transmission is house within the second transmission region. Each transmission includes a motor-interfacing shaft that interfaces with a respective electric motor, a drive-interfacing shaft that interfaces with a respective drive wheel of a vehicle, and a multi-stage gear train mechanically coupling the motor-interfacing shaft and the drive-interfacing shaft.

Systems are provided for a split differential housing. The split differential housing is bisected at an axis on a vertical plane. The split differential housing comprises a first housing member coupled to a second housing member at an interface centered on the vertical plane, wherein the axis is coaxial with a central axis of a drive axle.

A divisible housing of a fluid machine for a transmission to be received in the divisible housing is provided. The transmission provided for receiving in the divisible housing includes a large wheel and at least two pinion shafts which are in engagement with the large wheel. The divisible housing includes a first housing element and a second housing element which is connected to the first housing element via a parting joint. The at least two pinion shafts may be received in the parting joint. The parting joint includes a parting joint step, the at least two pinion shafts being receivable in the parting joint on both sides of the parting joint step.
