Abstract

A housing for a crankshaft starter generator is designed so as to be divisible and/or a crankshaft starter generator without a housing and with a stator is designed so as to be divisible.

First claim

The invention claimed is:

1. A crankshaft starter generator (CSG) housing divided circumferentially into at least two housing parts, the CSG housing is designed to be arranged between an engine and a transmission, and the CSG housing is designed to be divisible so that in a connected state, in which the CSG housing is connected to the engine and the transmission, one of the at least two housing parts is removable while others of the at least two housing parts remain connected to the engine and the transmission.

2. The crankshaft starter generator housing according to claim 1 , wherein in a fitted state, in which the CSG housing accommodates a rotor of a starter generator, the one of the at least two housing parts is removable to expose a partial region of teeth of the rotor.

3. The crankshaft starter generator housing according to claim 1 , wherein the at least two housing parts are of equal size.

4. The crankshaft starter generator housing according to claim 1 , wherein the at least two housing parts include one of two housing halves and four housing quarters.

5. The crankshaft starter generator housing according to claim 1 , further comprising a stator arranged in a positionally fixed manner on the inside of the housing, the stator having at least two stator parts.

6. The crankshaft starter generator housing according to claim 5 , wherein the at least two stator parts correspond to the at least two housing parts of the CSG housing such that each of the at least two stator parts is arranged on a radial inner of a corresponding one of the at least two housing parts.

7. The crankshaft starter generator housing according to claim 5 , wherein each of the at least two stator parts has a dedicated power line leadthrough to a central control unit.

8. The crankshaft starter generator housing according to claim 5 , wherein a power line leadthrough of the starter is arranged at an intersection of two of the at least two housing parts of the CSG housing.

9. The crankshaft starter generator housing according to claim 5 , further comprising grooves into which power line leadthrough cables emerging from the stator are placed, the grooves being surrounded and fixed in a watertight and dirttight manner by the CSG housing, the grooves being introduced at an intersection of two adjacent ones of the at least two housing parts of the CSG housing.

10. The crankshaft starter generator housing according to claim 1 , wherein the CSG housing comprises at least one of open cooling ducts and closed cooling ducts for transporting away the heat arising from the stator, wherein the cooling ducts are arranged in individual one of the at least two housing parts such that the cooling ducts of adjacent ones of the at least two housing parts fluidically connected.

11. The crankshaft starter generator housing according to claim 5 , wherein a cooling duct wall is at least partially formed by the stator, wherein the corresponding point of the stator is preferably coated with a rust prevention coating.

12. The crankshaft starter generator housing according to claim 10 , further comprising a tube element introduced at a first end region into a cooling duct of one of the at least two housing parts and introduced by a second, opposite end region into a cooling duct of an adjacent one of the at least two housing parts.

13. The crankshaft starter generator housing according to claim 12 , wherein the tube element is provided with at least one of a bevel, a conical design, a fit and a seal at least one of the end regions.

14. The crankshaft starter generator housing according to claim 5 , further comprising a sealing element arranged between the CSG housing and the stator.

15. The crankshaft starter generator housing according to claim 14 , wherein at least one of cooling ducts and power line leadthroughs are incorporated into the sealing element.

16. The crankshaft starter generator housing according to claim 5 , wherein the stator comprises an element that one of engages with a corresponding recess of one of the at least two housing parts and projects out of the CSG housing.
