Embodiment Construction

[0029] exist figure 1 shows in a perspective view the arrangement of a rear subframe 1 for the rear axle of the vehicle and a traction battery 2 at the front in the vehicle longitudinal direction x, which can be installed in an electrically driven motor vehicle. The subframe 1 is in figure 1 The center is configured as a rectangular closed structure and has subframe longitudinal supports 3 spaced apart from one another in the vehicle transverse direction y as well as a front transverse support 5 and a rear transverse support 7 . The two transverse supports run in the transverse vehicle direction y and connect the two subframe longitudinal supports 3 to one another at the front and rear corner points. The two subframe longitudinal bearings 3 extend forward and rearward along the vehicle longitudinal direction x correspondingly beyond the corner joints to form a longitudinal bearing front section 9 and a longitudinal bearing rear section 11 ( image 3 ).

[0030] The subframe...

Abstract

The invention relates to a vehicle body structure for a two-track vehicle. A rear axle of the vehicle body structure has an auxiliary frame (1), which has side auxiliary frame longitudinal bearing components (3) extending in a driving direction (FR). A traction battery (2) used for a vehicle motor is arranged in front of the auxiliary frame (1) along a longitudinal direction (x) of a vehicle. The auxiliary frame (1) is connected to a vehicle body through at least one front auxiliary frame bearing component (13) along the driving direction (FR). The auxiliary frame bearing component includes a bearing core (31) taken as an interior bearing component and a bearing acceptor (35) taken as an exterior bearing component. A vibration absorption unit (33) is arranged between the bearing core and the bearing acceptor and is characterized by forming the front auxiliary frame bearing component (13). At least one auxiliary frame longitudinal bearing component (3) extends towards the front of the longitudinal direction (x) of the vehicle to form an auxiliary frame side bearing component (31), which is connected to other battery-housing-side bearing component (35) in a situation that the middle of the bearing component is connected to the vibration absorption unit (33).

Description

technical field [0001] The invention relates to a body structure for a double-track vehicle according to the preamble of claim 1 . Background technique [0002] In electrically driven vehicles, the rear wheels can be driven by means of at least one electric machine. The electric motor can be supported by the rear axle carrier or the rear subframe on which the wheel control arms of the wheel suspensions for the rear wheels are articulated laterally. In order to supply the electric machine, the traction battery can be mounted in the direction of travel in front of the subframe at the rear of the vehicle. For the best use of the installation space, it is advantageous if the traction battery adjoins the axle carrier as closely as possible. [0003] An electrically driven vehicle is known from document WO 2014 195 104 A1. The rear-side subframe mounted in the body structure has lateral subframe longitudinal supports extending in the longitudinal direction of the vehicle, which...
