Embodiment Construction

[0066] exist figure 1 The axle subframe 2 shown in section in , has a subframe upper part 20 with a first wall 12 and a subframe lower part 21 with a second wall 13 , which are connected to one another. The subframe upper part 20 has a first recess 22 which is arranged in alignment with a second recess 23 of the subframe lower part 21 . A subregion of the support sleeve 30 is introduced through the first recess 22 . The support sleeve 30 has a first support sleeve region 31 , a second support sleeve region 32 and a central support sleeve recess 34 extending in the longitudinal direction of the support sleeve 30 , which is designed for the insertion of the fastening means ( For example, part of a bolt shank or pin shank). The first support sleeve region 31 has a support ring 33 at one end of the support sleeve 30 , which is placed on the side of the first wall 12 facing away from the second wall 13 and is welded thereto by means of a weld seam 24 . One end of the second supp...

Abstract

The invention relates to a fixing system and an axle auxiliary frame, the fixing system (1) is used to connect the axle auxiliary frame (2) to the body of the vehicle, which has a body side (4), an auxiliary frame side ( 5) and a support (3) with a support recess (6) and a sleeve (7) with a first end region (8), a second end region (9) and a sleeve recess (10). The subframe side (5) of the support (3) is at the first side (11) of the first wall (12) of the axle subframe (2) and the second end region (9) of the sleeve (7) ) can be arranged at the second wall (13) of the axle auxiliary frame (2) such that the bearing recess (6) and the sleeve recess (10) are arranged coaxially with each other. The bearing recesses and sleeve recesses are designed for the passage of the rods of the fastening means connecting the axle auxiliary frame to the bodywork. The body side (4) has a mounting surface (14) for mounting the body, and the support (3) has greater hardness than the sleeve (7).

Description

technical field [0001] The invention relates to a fastening system for connecting an axle auxiliary frame to a body of a vehicle and an axle auxiliary frame for connecting an axle to the body of a vehicle. Background technique [0002] The steerable front axle of a motor vehicle often has an axle subframe, on which transverse arms guiding the wheels are arranged on both sides. Known axle subframes are constructed as a multi-part plate structure and have, for example, two assembled subframe parts, which are also referred to as subframe upper part or subframe lower part. In order to connect the axle subframe to the body of the motor vehicle or to the carrier element of the body in shell, the subframe upper part and the subframe lower part have coaxial recesses for the insertion of connecting bolts. [0003] In order to strengthen the joint of the axle subframe at the body, a sleeve is used, which can be inserted into the recess and prevents the upper part of the subframe and ...
