Abstract

A chassis for an electrically powered vehicle, including a front wheel suspension and a rear wheel suspension, each having longitudinal control arms arranged on both sides and a torsion spring actively connected to the longitudinal control arms. The chassis includes a battery housing receiving a propulsion battery. A front transverse carrier extends between the respective longitudinal control arms of the front wheel suspension, and a rear transverse carrier extends between the respective longitudinal control arms of the rear wheel suspension. The respective transverse carriers are rigidly connected to the battery housing and couple the longitudinal control arms and the torsion spring.

Claims20

Dependent claims

A vehicle comprising:

a front wheel suspension including a left front longitudinal control arm, a right front longitudinal control arm, and a front torsion spring actively connected to at least one of the left front longitudinal control arm and the right front longitudinal control arm;
a rear wheel suspension including a left rear longitudinal control arm, a right rear longitudinal control arm, and a rear torsion spring actively connected to at least one of the left front longitudinal control arm and the right rear longitudinal control arm;
a battery housing;
a front transverse carrier rigidly connected to the battery housing and rotatably supporting the left front longitudinal control arm and the right front longitudinal control arm;
a rear transverse carrier rigidly connected to the battery housing and rotatably supporting the left rear longitudinal control arm and the right rear longitudinal control arm;
the left front longitudinal control arm and the right front longitudinal control arm each having a wheel supporting end and a transverse carrier mounting end, the front transverse carrier coupled to the transverse carrier mounting end of each of the left front longitudinal control arm and the right front longitudinal control arm;
the left rear longitudinal control arm and the right rear longitudinal control arm each having a wheel supporting end and a transverse carrier mounting end, the rear transverse carrier coupled to the transverse carrier mounting end of each of the left rear longitudinal control arm and the right rear longitudinal control arm;
and
the wheel supporting end of the left front longitudinal control arm and the right front longitudinal control arm positioned adjacent to the battery housing and the wheel supporting end of the left front longitudinal control arm and the right rear longitudinal control arm positioned adjacent to the battery housing.
