A steering system for a wheel of a vehicle comprises a pivot member having multiple pivot-node locations, and connectable at a first pivot-node location to a sub-frame of the wheel, a steering rod actuatable to rotate the wheel about a steering axis and mechanically coupled with the pivot member to be co-pivotable with the pivot member, and a suspension-connector rod having a first end that is connected to the pivot member at a second pivot-node location, and having at a second end that is connectable to a suspension arm linking the wheel of the vehicle to the sub-frame. When the steering system is installed in the vehicle, a lateral force acting upon the wheel is transmitted via the steering rod to the pivot member so as to rotate the pivot member, and the rotation is effective to transmit a substantially-vertical force vector to the sub-frame.

Steering systems for vehicles

A wheel suspension system can include a wheel interface having a wheel interface axis about which a wheel rotates when connected to the wheel interface, and an arm connected to the wheel interface and rotatable with respect to the wheel interface about a first axis, wherein the arm is connectable to a reference frame and rotatable with respect to the reference frame about a second axis. In some embodiments, the first axis and the second axis are offset with respect to the wheel interface axis. In some embodiments, the first axis and the second axis are off-parallel.

Wheel suspension system with off-wheel-center arm

Generally, a suspension system for a wheel of a vehicle is disclosed. The system may include at least one pair of arms each including a first arm and a second arm. Each of the first arm and the second arm of the at least one pair of arms may have a first end adapted to be rotatably connected to a wheel interface and a second end adapted to be rotatably connected to a reference frame of the vehicle, while the first arm and the second arm may be set across each other and define a mobile steering axis at a virtual intersection therebetween such that the mobile steering axis moves with respect to the reference frame when the wheel interface changes its steering angle relative to the reference frame.

Vehicle corner modules (VCMs) connectable to a VCM-connection interface of a reference-frame of a vehicle platform, for regulating motion of a vehicle. When a wheel is mounted on a wheel-hub assembly of the VCM, a vehicle-connection interface of the VCM is disposed within a cylindrical footprint of the wheel. At least one of the at least one subsystem of the VCM is accommodated between the wheel-hub assembly and the vehicle-connection interface. Vehicle platforms are connectable to the VCMs. The connection of the vehicle platform to the VCM may include connection of subsystems of the VCM to electronic or flow subsystems mounted on the vehicle platform by connection of two portions of a multi-interface connection-element.
