Abstract

The present disclosure relates to a frame structure for a vehicle comprising a front wheel suspension arrangement for suspending a pair of front wheels of the vehicle and a rear wheel suspension arrangement for suspending a pair of rear wheels of the vehicle, wherein the frame structure comprises a load bearing frame arrangement arranged to be positioned at a transversal center portion of the vehicle, the load bearing frame arrangement comprising a first member and a second member, each of the first and second members forming a diagonal extension as seen in a transversal cross section of the load bearing frame arrangement, wherein the diagonal first and second members extend longitudinally between the front wheel suspension arrangement and the rear wheel suspension arrangement, wherein the diagonal extension of the first member interconnects with the diagonal extension of the second member forming a connection point between the first and second members.

First claim

1 . A frame structure for a vehicle comprising:
a front wheel suspension arrangement for suspending a pair of front wheels of the vehicle, and a rear wheel suspension arrangement for suspending a pair of rear wheels of the vehicle, wherein the frame structure comprises:
a load bearing frame arrangement arranged to be positioned at a transversal center portion of the vehicle,
the load bearing frame arrangement comprising:
a first member, and
a second member,
wherein each of the first and second members form a diagonal extension as seen in a transversal cross section of the load bearing frame arrangement,

wherein the first and second members extend longitudinally between the front wheel suspension arrangement and the rear wheel suspension arrangement, and wherein the diagonal extension of the first member interconnects with the diagonal extension of the second member forming a connection point between the first and second members.

2 . The frame structure of claim 1 , wherein the connection point is positioned along the diagonal extension of the first and second members.

3 . The frame structure of claim 1 , wherein the connection point is positioned at the transversal center portion of the vehicle.

4 . The frame structure of claim 1 , wherein the first and second members are connected to each other by a fastening element to form the connection point.

5 . The frame structure of claim 1 , wherein the diagonal extension of the first member interconnects with the diagonal extension of the second member forming an X-shaped, longitudinally extending, load carrying beam.

6 . The frame structure of claim 1 , further comprising a plurality of brackets connected to the load bearing frame arrangement.

7 . The frame structure of claim 6 , wherein each of the plurality of brackets is connected to the load bearing frame arrangement and extends transversally away from the connection point.

8 . The frame structure of claim 6 , wherein each of the plurality of brackets are positioned along the longitudinal extension of the load bearing frame arrangement at a predetermined distance from each other.

9 . The frame structure of claim 1 , further comprising an upper panel structure fixed to a vertical upper portion of the load bearing frame arrangement.

10 . The frame structure of claim 9 , wherein the upper panel structure comprises an extension in the transversal and longitudinal direction of the load bearing arrangement.

11 . The frame structure of claim 9 , wherein the upper panel structure comprises an access lid positioned vertically above the connection point.

12 . The frame structure of claim 9 ,
wherein the upper panel structure is fixated to a vertical upper portion of the plurality of brackets.

13 . The frame structure of claim 6 , further comprising an upper panel structure fixed to a vertical upper portion of the load bearing frame arrangement,
wherein the upper panel structure is fixated to a vertical upper portion of the plurality of brackets.

14 . The frame structure of claim 1 , further comprising a lower panel structure fixated to a vertical lower portion of the load bearing frame arrangement.

15 . A vehicle comprising:
a front wheel suspension arrangement for suspending a pair of front wheels of the vehicle, a rear wheel suspension arrangement for suspending a pair of rear wheels of the vehicle, and a frame structure of claim 1 , wherein the frame structure extends between the front wheel suspension arrangement and the rear wheel suspension arrangement.

16 . The vehicle of claim 15 , further comprising:
an electric machine for propelling the vehicle, and a plurality of vehicle batteries electrically connected to the electric machine, wherein the vehicle batteries are connected to the load bearing frame arrangement transversally outside the connection point.

17 . The vehicle of claim 15 , wherein the connection point of the frame structure is positioned at the transversal center portion of the vehicle.

18 . The vehicle of claim 15 , wherein the first and second members of the frame structure are connected to each other by a fastening element to form the connection point.

19 . The vehicle of claim 15 , wherein the frame structure further comprises a plurality of brackets connected to the load bearing frame arrangement.

20 . The vehicle of claim 15 , wherein the frame structure further comprises an upper panel structure fixed to a vertical upper portion of the load bearing frame arrangement.
