front and rear cross members, said lateral longitudinal members converging at respective front and rear corner-joint parts with the front and rear cross members; at least one rear control arm console having console wings, with a rear wheel control arm of a wheel suspension of the motor vehicle being articulately connected between the console wings, one of the console wings having a mounting section; and at least one mount support for supporting an aggregate mount for a drive aggregate of the vehicle, wherein the mount support is formed on the mounting section of the one of the console wings. ## Claims ### Claim 1 An auxiliary frame for a front axle of a two-track motor vehicle comprising: lateral longitudinal members extending in a longitudinal direction of the motor vehicle; front and rear cross members, said lateral longitudinal members converging at respective front and rear corner-joint parts with the front and rear cross members; at least one rear control arm console having console wings, with a rear wheel control arm of a wheel suspension of the motor vehicle being articulately connected between the console wings, one of said console wings having a mounting section; and at least one mount support formed as a guide sleeve for supporting an aggregate mount for a drive aggregate of the vehicle, said mount support being formed on the mounting section of the one of the console wings. ### Claim 2 (depends on 1) The auxiliary frame of claim 1, wherein the rear corner-joint parts are configured as a respective welding group, and wherein the cross member, the longitudinal member, a flat stiffening element and the vehicle body are connected on the welding group. ### Claim 3 (depends on 2) The auxiliary frame of claim 2, wherein the cross member, the longitudinal member, the flat stiffening element and the vehicle body are connected on the welding group with a force fitting or material bonding connection. ### Claim 4 (depends on 1) The auxiliary frame of claim 1, wherein the mount support is constructed as a guide sleeve which is providable as a separate component, and which delimits a bearing eye for the aggregate mount. ### Claim 5 (depends on 1) The auxiliary frame of claim 1, wherein the mounting section has a connection contour, which partially encloses an outer circumference of the mount support and is connected with the mount support in a materially bonding manner. ### Claim 6 (depends on 5) The auxiliary frame of claim 5, wherein the connection contour is a cutting edge which delimits a hole in the respective formed sheet metal part. ### Claim 7 (depends on 1) The auxiliary frame of claim 1, wherein the mounting section has a connection contour, which continuously encloses an outer circumference of the mount support and is connected with the mount support in a materially bonding manner. ### Claim 8 (depends on 1) The auxiliary frame of claim 1, wherein the corner-joint parts each have a respective base body, which is connected with at least one of the console wings of a respective one of the corner-joint parts in a materially bonding manner. ### Claim 9 (depends on 8) The auxiliary frame of claim 8, wherein the at least one console wing is provided as a separate component and is connected with the base body in a materially bonding manner. ### Claim 10 (depends on 8) The auxiliary frame of claim 8, wherein the base body and the console wing are respective formed sheet metal parts. ### Claim 11 (depends on 8) The auxiliary frame of claim 8, wherein the console wings of the rear control arm console are connected with the base body as separate components in a materially bonding manner. ### Claim 12 (depends on 11) The auxiliary frame of claim 11, wherein the console wings of the rear control arm console are formed sheet metal parts. ### Claim 13 (depends on 8) The auxiliary frame of claim 8, wherein the longitudinal member, the rear cross member, a flat stiffening element and the at least one console wing of the rear control arm console converge star-like at the base body. ### Claim 14 An auxiliary frame for a front axle of a two-track motor vehicle comprising: lateral longitudinal members extending in a longitudinal direction of the motor vehicle; front and rear cross members, said lateral longitudinal members converging at respective front and rear corner-joint parts with the front and rear cross members; at least one rear control arm console having console wings, with a rear wheel control arm of a wheel suspension of the motor vehicle being articulately connected between the console wings, one of said console wings having a mounting section; and at least one mount support for supporting an aggregate mount for a drive aggregate of the vehicle, said mount support being formed on the mounting section of the one of the console wings, wherein the one of the console wings of the rear control arm console has an end that protrudes from the auxiliary frame, said end being provided with a vehicle body connection point at which the one of the console wings is connectable to the vehicle body. ### Claim 15 (depends on 14) The auxiliary frame of claim 14, wherein the mounting section is configured hollow cylindrically, said mount support being insertable into the hollow cylindrical mounting section. ### Claim 16 (depends on 15) The auxiliary frame of claim 15, wherein the mount support is weldable to the mount support being weldable to the hollow cylindrical mounting section. ### Claim 17 An auxiliary frame for a front axle of a two track motor vehicle comprising: lateral longitudinal members extending in a longitudinal direction of the motor vehicle; front and rear cross members, said lateral longitudinal members converging at respective front and rear corner-joint parts with the front and rear cross members; at least one rear control arm console having console wings, with a rear wheel control arm of a wheel suspension of the motor vehicle being articulately connected between the console wings, one of said console wings having a mounting section; and at least one mount support for supporting an aggregate mount for a drive aggregate of the vehicle, said mount support being formed on the mounting section of the one of the console wings, wherein the rear corner-joint parts are separate components on which the longitudinal members and cross members and the one of the console wings of the rear control arm console are connected. ### Claim 18 An auxiliary frame for a front axle of a two-track motor vehicle comprising: lateral longitudinal members extending in a longitudinal direction of the motor vehicle; front and rear cross members, said lateral longitudinal members converging at respective front and rear corner-joint parts with the front and rear cross members; at least one rear control arm console having console wings, with a rear wheel control arm of a wheel suspension of the motor vehicle being articulately connected between the console wings, one of said console wings having a mounting section; and at least one mount support for supporting an aggregate mount for a drive aggregate of the vehicle, said mount support being formed on the mounting section of the one of the console wings, wherein the corner-joint parts each have a respective base body, which is connected with at least one of the console wings of a respective one of the corner-joint parts in a materially bonding manner, and wherein the rear corner-joint parts have a multilayered construction in which the mount support, the one of the console wings of the rear control arm console and the base body are arranged above one another other in a vertical direction of the motor vehicle. ### Claim 19 (depends on 18) The auxiliary frame of claim 18, wherein the one of the console wings of the rear control arm console and the base body are aligned with each other in the vertical direction of the motor vehicle.
