Abstract

A subframe assembly for a vehicle includes a multipart subframe having two spaced-apart longitudinal members and two spaced-apart cross members connecting the longitudinal members. A transfer case is supported on the subframe between the longitudinal and cross members and has an input shaft in driving relation to two output shafts, and a bearing element which extends in axis-parallel relation to the input shaft and which is shifted in a direction of one of the longitudinal members and projects from the transfer case. A first one of the cross members is crossed by a portion of the transfer case at a crossing section and has two shell parts connected to one another at least at one area. Each shell part has a bracket, with the bracket of one shell part and the bracket of the other shell part jointly forming a bearing mount for the bearing element.

First claim

What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims and includes equivalents of the elements recited therein:

1. A subframe assembly for a vehicle, comprising:
a multipart substantially horizontal subframe having two longitudinal members in spaced-apart relationship, and two cross members disposed in spaced-apart relationship and connecting the longitudinal members;
a transfer case supported on the subframe between the longitudinal and cross members, said transfer case having an input shaft in driving relation to two output shafts, and a bearing element which extends in axis-parallel relation to the input shaft and which is shifted in a direction of one of the longitudinal members and projects from the transfer case,
wherein a first one of the cross members is crossed by a portion of the transfer case at a crossing section and has two shell parts connected to one another at least at one area, the shell parts both extending in a longitudinal direction of the one cross member and are spaced from one another in a transverse direction of the one cross member, each said shell part having a bracket extending vertically upwardly from the shell part, with the bracket of one of the shell parts and the bracket of the other one of the shell parts jointly forming a bearing mount for the bearing element.

2. The subframe assembly of claim 1 , wherein the first one of the cross members has a curved portion which crosses underneath the portion of the transfer case.

3. The subframe assembly of claim 1 , wherein the first one of the cross members has a cross section which substantially corresponds in an area of the curved portion to a remainder of the first one of the cross members.

4. The subframe assembly of claim 1 , wherein the input shaft extends substantially at level with the longitudinal members.

5. The subframe assembly of claim 1 , wherein the two shell parts form together a downwardly open profile, as viewed in a vertical vehicle direction.

6. The subframe assembly of claim 1 , wherein the transfer case has two of said bearing element, wherein a second one of the cross members has two bearing mounts for receiving the bearing elements.

7. The subframe assembly of claim 6 , wherein the two bearing mounts are sized to extend widthways through the second one of the cross members.

8. The subframe assembly of claim 1 , wherein the first one of the cross members is arranged at a leading end of the subframe, as viewed in a longitudinal vehicle direction.

9. The subframe assembly of claim 1 , wherein the shell parts are formed as malleable sheet metal parts.

10. The subframe assembly of claim 1 , wherein the subframe is configured as a welding assembly.

11. A vehicle, comprising a subframe assembly which includes a multipart substantially horizontal subframe having two longitudinal members in spaced-apart relationship, and two cross members disposed in spaced-apart relationship and connecting the longitudinal members, a transfer case supported on the subframe between the longitudinal and cross members, said transfer case having an input shaft and a bearing element which extends in axis-parallel relation to the input shaft and which is shifted in a direction of one of the longitudinal members and projects from the transfer case, wherein a first one of the cross members is crossed by a portion of the transfer case at a crossing section and has two shell parts connected to one another at least at one area, the shell parts both extending in a longitudinal direction of the one cross member and are spaced from one another in a transverse direction of the one cross member, each said shell part having a bracket extending vertically upwardly from the shell part, with the bracket of one of the shell parts and the bracket of the other one of the shell parts jointly forming a bearing mount for the bearing element,
wherein a first one of the cross members is crossed by a portion of the transfer case at a crossing section and has two shell parts connected to one another at least at one area, the shell parts both extending in a longitudinal direction of the one cross member and are spaced from one another in a transverse direction of the one cross member, each said shell part having a bracket extending vertically upwardly from the shell part, with the bracket of one of the shell parts and the bracket of the other one of the shell parts jointly forming a bearing mount for the bearing element.
