Embodiment Construction

[0034] In the drawings, the same reference numerals are used for the same or similar components, although repeated descriptions are omitted for brevity.

[0035] figure 1 A perspective view of an axle device 1 with an axle subframe 2 according to the invention is shown. A coupling position 3 for connecting a suspension arm not shown in detail here is provided on the axle subframe 2. The entire axle device 1 is coupled to a vehicle body not shown in detail from below. To this end, a plurality of connection locations 4 are provided on the axle subframe 2 and are connected to different corresponding locations of the vehicle body. In addition, figure 1 The rear body connecting device h is shown, which extends as an extension of the axle subframe 2. A predetermined bending position K is provided between the rear body connecting device h and the axle sub-frame 2. In the event of a collision, the axle sub-frame 2 moves downwards around the predetermined bending position A to move to t...

Abstract

The present invention relates to an axle arrangement (1) used for a motor car. A wishbone or double wishbones are coupled to a motor car body over an axle auxiliary frame (2) and the axle auxiliary frame (2) is provided with a front body attachment (5) for connecting with the motor car body. The front body attachment (5) is in threaded connection with the motor car body, and is disengaged from the motor car body when a force threshold value is reached. Hereon when a corresponding force is introduced, destructive damage to the motor car body is prevented through the axle auxiliary frame (2), thereby reducing maintenance cost in specific motor car accidents. According to the axle arrangement provided by the invention, the front body attachment (5) is constructed to an integrated tower-shaped deep punched component. The deep punched component has high torsion resistance and furthermore the structural tissue of the deep punched component is not affected because of no welding technical connector or other similar connections.

Description

Technical field [0001] The invention relates to an axle device for automobiles according to the features of the preamble of claim 1. Background technique [0002] Nowadays, axle devices are used in automobiles, which are connected to a self-supporting body as a separate complex component. The axle device itself here includes at least an axle sub-frame, and various other components of the axle device are connected to the axle sub-frame. These components include, for example, a plurality of guide rods, which kinematically couple the wheel or wheel frame to the axle subframe. The guide rod may be, for example, a double-wishbone guide rod or a single guide rod, which jointly form a four-bar or five-bar rear axle. The guide rod itself is connected to the axle subframe through a rubber-metal support and is connected to the wheel frame on the wheel side, and the wheel is connected to the wheel frame through a corresponding hub. [0003] The axle subframe is basically a bending and tors...
