Abstract

A subframe for a motor vehicle includes at least one transverse structure oriented in a transverse direction of the vehicle, a first and a second longitudinal member oriented in a longitudinal direction of the vehicle and connected to the at least one transverse structure by respective first and second cast joints respectively arranged between the first longitudinal member and the at least one transverse structure and the second longitudinal member and the at least one transverse structure, the first and second cast joints each having bearing connection points for fastening an engine bearing. The subframe also includes connection parts, one of which is provided for each of the first and second cast joints, the connection parts each having at least one other bearing connection point for fastening the engine bearing, and multiple bearing sites via which the connection parts are fastenable on the at least one transverse structure and on the bearing connection points of the first and second cast joints.

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 for a motor vehicle, comprising:
at least one transverse structure oriented in a transverse direction of the vehicle;
a first and a second longitudinal member oriented in a longitudinal direction of the vehicle and connected to the at least one transverse structure by respective first and second cast joints respectively arranged between the first longitudinal member and the at least one transverse structure and the second longitudinal member and the at least one transverse structure, said first and second cast joints each having bearing connection points for fastening an engine bearing; and
separate connection parts, one of said connection parts provided for each of the first and second cast joints, said connection parts each having at least one other bearing connection point for fastening the engine bearing, and multiple bearing sites via which the connection parts are fastenable on the at least one transverse structure and on the bearing connection points of the first and second cast joints, said connection parts being spaced apart in vertical direction from the at least one transverse structure so that a passage is formed between the at least one transverse structure and each of the connection parts.

2. The subframe of claim 1 , wherein the at least one transverse structure comprises a transverse member and a shear field, and the connection parts each have two said bearing sites on a side facing the at least one transverse structure, said connection parts being fastened with the transverse member and the shear field via the bearing sites.

3. The subframe of claim 2 , wherein the two bearing sites are arranged and the connection parts are configured so that a free corridor is formed in the transverse direction of the motor vehicle.

4. The subframe of claim 1 , wherein the connection parts are connected with the cast joints and the transverse structure by means of threaded connections.

5. The subframe of claim 1 , wherein the connection parts are configured as cast parts.
