A chassis frame module for an electric vehicle may include a chassis frame including a pair of side frames, a pair of inclined frames connected to front ends of the respective side frames, respectively, and a distance between the pair of inclined frames decreases toward the front, a front frame connected to the inclined frames, and a rear frame connected to rear ends of the pair of side frames, a battery disposed between the pair of side frames, and a plurality of wire assemblies disposed between the side frame and the battery and in a longitudinal direction of the side frame, and being configured to house a wire in an internal space thereof.

The present disclosure relates to a chassis (1) for a motor vehicle, comprising a passenger compartment cell (2), a front frame (3) and a rear frame (4), which are arranged along a longitudinal direction (100) of the chassis (1). The frame front (3) and the rear frame (4) each comprise two longitudinal members (31, 32; 41, 42) and a cross member (35; 45) forming a substantially C-shaped structure. The chassis (1) allows the adjustment of the track width and/or the pitch of the motor vehicle. To adjust the track width, the chassis (1) is adapted for the attachment of each longitudinal member (31, 32; 41, 42) of a frame (3, 4) to the passenger compartment cell (2) at a plurality of positions that are spaced apart in the transverse direction, in such a way as to allow an adjustment of the transverse distance between the two longitudinal members (31, 32; 41, 42). To adjust the pitch, each longitudinal member (31, 32; 41, 42) of a frame (3, 4) is provided with at least one attaching assembly (53) for attaching a suspension (7) of a respective wheel of the motor vehicle. The attaching assembly (53) is adapted for attaching the suspension (7) at a plurality of positions that are spaced apart in the longitudinal direction, in such a way as to allow an adjustment of the longitudinal distance of the suspension (7) from the passenger compartment cell (2).
