Embodiment Construction

[0028] 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 and has 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 sub-frame 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 ).

Abstract

The invention relates to a body structure for a double-track vehicle, the rear axle of which has a subframe (1) with lateral subframe longitudinals extending in the direction of travel (FR) Carrier (3) with a traction battery (2) for the vehicle electric motor arranged in front of the subframe (1) in the longitudinal direction of the vehicle (x), the subframe (1) being positioned forward in the direction of travel (FR) by at least one The subframe support (13) of the part is connected on the vehicle body, and the subframe support includes a support core (31) as an inner support part and a support receiver (35) as an outer support part, between the support core and the support A damping unit (33) is arranged between the receptacles, characterized in that at least one of the longitudinal subframe supports (3) extends in the vehicle longitudinal direction (x) in order to form the front subframe support (13). Extended forward is a subframe-side bearing part (31), which is connected to a further battery housing-side bearing part (35) with the damping unit (33) interposed therebetween.

Description

technical field [0001] The invention relates to a body structure for a double track vehicle. 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 are connected to one another by trans...
