Abstract
Abstract A frame for a vehicle having two side members, two longitudinal members and two cross members. Each side member extends between a respective front wheel and rear wheel, and the two longitudinal members are arranged in at least one end region of the vehicle and, throughout at least portions of their lengths, are laterally displaced with respect to the side members in the direction toward the longitudinal axis of the vehicle. The cross members extend in opposite directions from the longitudinal propeller shaft tunnel of the vehicle and have projecting portions extending into the end region of the vehicle, these projecting portions supporting downwardly inclined ends of respective ones of the longitudinal members. The cross members are force-transmittingly connected with the tunnel, with the corresponding side members, and with a base plate, and are provided with attachments for supporting an axle mount.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
186 words
A frame for a vehicle, particularly a motor vehicle, the frame having a. means forming two side members each extending between a respective front wheel and rear wheel of the vehicle; b. means forming two longitudinal members arranged in at least one end region of the vehicle, said longitudinal members, throughout at least portions of their lengths, being laterally displaced with respect to the side members in the direction toward the longitudinal axis of the vehicle, said longitudinal members having downwardly inclined ends; c. means forming a central longitudinal propeller shaft tunnel; d. means forming two cross members which extend in opposite directions from said longitudinal propeller shaft tunnel of the vehicle, said cross members having projecting portions extending into said end region of the vehicle and supporting said downwardly inclined ends of respective ones of said longitudinal members; e. means forming a bottom plate extending from said tunnel to each of said side members; and f. said cross members being force-transmittingly connected with said tunnel, with the corresponding side members, and with said bottom plate, and being provided with attachments for supporting an axle mount.
Claim 2
Dependent Claim
186 words
A frame for a vehicle, particularly a motor vehicle, the frame having a. means forming two side members each extending between a respective front wheel and rear wheel of the vehicle; b. means forming two longitudinal members arranged in at least one end region of the vehicle, said longitudinal members, throughout at least portions of their lengths, being laterally displaced with respect to the side members in the direction toward the longitudinal axis of the vehicle, said longitudinal members having downwardly inclined ends; c. means forming a central longitudinal propeller shaft tunnel; d. means forming two cross members which extend in opposite directions from said longitudinal propeller shaft tunnel of the vehicle, said cross members having projecting portions extending into said end region of the vehicle and supporting said downwardly inclined ends of respective ones of said longitudinal members; e. means forming a bottom plate extending from said tunnel to each of said side members; and f. said cross members being force-transmittingly connected with said tunnel, with the corresponding side members, and with said bottom plate, and being provided with attachments for supporting an axle mount.
Claim 3
Dependent Claim
26 words
A frame as defined in claim 1, wherein each cross member is closed off by an upwardly inclined, bent over end part of said bottom plate.
Claim 4
Dependent Claim
32 words
A frame as defined in claim 2, wherein each cross member has, throughout substantially its length, a section which, taken in a longitudinal plane of the vehicle, is at least approximately trapezoidal.

A frame as defined in claim 1, wherein said cross members are box girders.
Claim 6
Dependent Claim
41 words
A frame as defined in claim 1, wherein at least said downwardly inclined ends of said longitudinal members, said cross members, said side members, said bottom plate, and said propeller shaft tunnel are arranged at least approximately at the same level.
Claim 7
Dependent Claim
33 words
A frame as defined in claim 1, wherein said means forming said two cross members are constituted by separate components each of which serves as a respective one of said two cross members.
