Dual-axle vehicle corner assembly

A dual-axle vehicle corner assembly comprising:

• a sub-frame;
• a first arm connected to the sub-frame and rotatable with respect to the sub-frame about a first arm axis, the first arm having a first axle axis about which a first wheel rotates when connected to the first arm;
• a second arm connected to the sub-frame and rotatable with respect to the sub-frame about a second arm axis, the second arm having a second axle axis about which a second wheel rotates when connected to the second arm;
• and
• a suspension system comprising a piston assembly interconnecting the first arm and the second arm, the piston assembly is to controllably increase and decrease a length of the piston assembly to control a distance between the first axle axis and the second axle axis;
• wherein the first arm axis, the first axle axis, the second arm axis and the second axle axis are substantially parallel to each other,
• wherein the piston assembly comprising:
• a housing connected to the first arm;
• a first spring-loaded member and a second spring-loaded member positioned within the housing, the first spring-loaded member and the second spring-loaded member being parallel to each other and being connected to the second arm;
• wherein springs of the first spring-loaded member and the second spring-loaded member are preloaded to set the distance between the first axle axis and the second axle axis.
