Abstract: A wiper motor having a gearbox housing which comprises a pot-shaped main body for forming a receiving space for a gear mechanism is disclosed. An opening in the main body can be closed by a gearbox cover, and a plurality of latching connections, which act in the direction of a joining direction between the main body and the gearbox cover, are formed between the main body and the gearbox cover. Each comprise an elastically deformable first latching element and a second latching element which interacts with the first latching element in a form-fitting manner, and wherein centring means are provided on the gearbox housing for the play-free positioning of the gearbox cover relative to the main body in a rotational angle position, which extends perpendicularly to the joining direction, between the main body and the gearbox cover.

Abstract: Techniques for joining nodes and subcomponents are presented herein. An additively manufactured first node or subcomponent has a groove. An additively manufactured second node or subcomponent has a tongue configured to extend into and mate with the groove to form a tongue-and-groove connection between the first and second node or subcomponent. In some aspects, the tongue-groove connection may extend substantially around a periphery of the node or subcomponent. In other aspects, a first subcomponent having a fluid pipe interface may be coupled via a tongue-groove connection to a second subcomponent having a fluid pipe interface, thereby enabling fluid to flow between subcomponents of the resulting integrated component.

Abstract: Embodiments of a system, method and apparatus for a gear are disclosed. For example, a metallic gear hub can include an axis of rotation and metallic gear teeth. The metallic gear teeth can be smaller than a final gear teeth size of the gear. The metallic gear teeth can be co-planar with the axis. In addition, the metallic gear teeth can be non-orthogonal to the axis. A polymer layer can be located on the metallic gear teeth to form polymer gear teeth on the metallic gear teeth. The polymer gear teeth can form the final gear teeth size of the gear.

Abstract: A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. A shift control circuit operates a shift actuator using a first opposing pulse command and a first actuating pulse command, and releases pressure with shift actuating and opposing volumes of the shift actuator upon determining a shift completion event.
