Problems solved by technology

As a result, the assembly of the axle auxiliary frame on the body can become significantly more difficult or impossible
In addition, it is impossible to introduce fixtures in after-sales service situations
In addition, fully tempered sleeves are very expensive to manufacture
Finally, the known sleeves have the disadvantage that they cannot be connected firmly enough to the axle auxiliary frame

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 present invention relates to a fastening system and an axle subframe. The fastening system 1 is used to fasten the axle subframe 2 to a car body, is equipped with a supporting member 3 with a car body side 4, a subframe side 5 and a supporting gap 6 and a sleeve 7 with a first end part area 8, a second end part area 9 and a sleeve gap 10. The subframe side 5 of the supporting member 3 is at the first side 11 of a first wall 12 of the axle subframe 12, and the second end part area 9 of the sleeve 7 is at the second wall 13 of the axle subframe 2, so that the supporting gap 6 and the sleeve gap 10 are arranged coaxially mutually. The supporting gap and the sleeve gap are used to thread a rod for connecting the axle subframe and a fixing device of the car body, the car body side 4 is equipped with an installing surface 14 used for installing the car body, and the supporting member 3 has a larger 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 ...
