Housing with two aligned housing parts for a unit of a vehicle drive train

A housing (1) for an assembly of a vehicle drive-train comprising:

• a first housing component (1A),
• a second housing component (1B),
• the first and the second housing components (1A, 1B) being aligned with and coupled to one another, and
• a shaft (6) for supporting a structural element (7) of the assembly being arranged inside the housing (1),
• the shaft (6) being respectively supported in the first and in the second housing components (1A, 1B), and
• the shaft (6) being configured to align the first and the second housing components (1A, 1B) with one another.

A transmission for a vehicle drive-train, comprising:

• at least one transmission stage,
• a housing (1) for accommodating structural elements of the transmission stage on an inside of the housing,
• the housing (1) having a first housing component (1A) and a second housing component (1B),
• the first and the second housing components (1A, 1B) being aligned with and coupled to one another,
• a shaft (6) for supporting a structural element (7) of the assembly arranged inside the housing (1),
• the shaft (6) being respectively supported in the first and in the second housing component (1A, 1B), and
• the shaft (6) being configured to align the first and the second housing components (1A, 1B) with one another.

A method for producing a housing (1) having a first housing component (1A) and a second housing component (1B), the first and the second housing components (1A, 1B) are aligned with and coupled to one another, and a shaft (6) for supporting a structural element (7) of the assembly arranged inside the housing (1), the shaft (6) is supported respectively in the first and in the second housing component (1A, 1B), the shaft (6) being configured to align the first and the second housing components (1A, 1B) with one another, the method comprising:

• producing the first housing component (1a)
• producing the shaft (6);
• producing the second housing component (1B);
• inserting one end of the shaft (6) into an opening or recess (1D) in an end face of the first housing component (1A) such that an other end of the shaft (6) projects beyond the end face;
• bringing together the first and the second housing components (1A, 1B) so that the other end of the shaft (6) is inserted into an opening or recess (1D) in an end face of the second housing component (1B), such that a first alignment stage of the housing components (1A, 1B) with one another occurs;
• and
• bringing the first and the second housing components (1A, 1B) closer together such that a centering collar (1C) on one of the end faces fits together with a corresponding shoulder (1E) on the other end face, such that a further alignment stage of the housing components (1A, 1B) with one another occurs.
