Vehicle corner modules and systems and methods for installation thereof
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.
1. A method for installing a Vehicle Corner Module (VCM) on a reference frame of a vehicle, the VCM including a sub-frame having a vehicle-connection interface for reversible mechanical connection of the VCM to the VCM-connection interface of the reference frame; a wheel-hub for mounting of a wheel thereon; and at least one subsystem of the vehicle, selected from a group of subsystems consisting of a drive subsystem, a steering subsystem, a suspension subsystem, and a braking subsystem, the method comprising:
aligning the vehicle-connection interface with the reference-frame, such that the vehicle-connection interface is disposed between upper and lower surfaces of the reference frame; and
without changing the height alignment between the vehicle-connection interface of the VCM and the reference-frame, mechanically connecting the at least one VCM to the reference-frame by engagement of the vehicle-connection interface with a VCM-connection interface of the reference frame, and, following the engagement, moving the VCM-portion relative to the vehicle-platform-portion until they are connected,
wherein moving the VCM-portion relative to the vehicle-platform-portion includes actuating motion of the VCM-portion by a mechanical mechanism that extends between a back portion of the VCM and a front portion of the VCM.
2. The method of claim 1 , further comprising connecting the VCM to multiple electronic or flow subsystems of the vehicle by connecting a VCM-portion of a multi-interface connection-element, mounted on the sub-frame, to a vehicle-platform portion of the multi-interface connection-element, forming part of the reference frame.
3. The method of claim 1 , wherein the mechanically connecting comprises moving the VCM laterally, in a direction perpendicular to a longitudinal axis of the reference-frame, for the vehicle-connection interface to engage the VCM-connection interface.
4. The method of claim 1 , wherein the mechanically connecting includes moving the VCM longitudinally, in a direction parallel to a longitudinal axis of the reference-frame, for the vehicle-connection interface to engage the VCM-connection interface.
5. The method of claim 1 , wherein:
the VCM-connection interface comprises a bar extending from the reference frame in a direction parallel to a longitudinal axis of the reference frame,
the vehicle-connection interface comprises a clamp including an opening, the clamp adapted to be clamped onto the bar, and
the mechanically connecting includes mounting the clamp onto the bar.
6. The method of claim 5 , wherein the mounting of the clamp onto the bar includes sliding of the clamp onto the bar.
7. The method of claim 6 , further comprising connecting at least one bumper to the reference frame, wherein the connecting of the bumper occurs after the sliding of the clamp.
8. The method of claim 6 , further comprising connecting at least one bumper to the reference frame, wherein the connecting of the bumper occurs prior to the sliding of the clamp.
9. The method of claim 2 , wherein each of the VCM-portion and the vehicle-platform-portion of the multi-interface connection-element comprises a plurality of connection interfaces, each associated with one of a plurality of electronic or flow subsystems.
10. The method of claim 1 , wherein only one of the VCM-portion and the vehicle-platform-portion is movable, and the other is stationary.
11. The method of claim 1 , wherein the mechanical mechanism actuating motion of the VCM-portion is remote to the location of the VCM-portion.
12. The method of claim 1 , wherein the mechanical mechanism comprises a fastener connected to the VCM-portion by a connector cable, and wherein the actuating motion comprises operating the connector fastener to transfer movement actuation forces from the fastener to the VCM-portion.
13. The method of claim 1 , wherein the mechanical mechanism comprises a fastener connected to the VCM-portion, and wherein actuating motion comprises operating the fastener to transmit movement actuation forces to the VCM portion by fluid communication via the conduit.
14. The method of claim 1 , wherein actuation of motion of at least one of the VCM-portion and the vehicle-platform portion is by an electrical motor.
15. The method of claim 14 , wherein the electrical motor is adapted to be remotely operated by a remote controller.
16. The method of claim 2 , wherein the connecting is carried out from a front side of the VCM, regardless of the positioning of the VCM connector within the VCM.
17. The method of claim 2 , wherein each of the VCM-portion and the vehicle-platform-portion of the multi-interface connection-element comprises a plurality of connection interfaces, each associated with at least one electronic subsystem and at least one flow subsystem of the multiple electronic and/or flow subsystems.
18. The method of claim 1 , wherein only the VCM-portion is movable and the vehicle-platform-portion is stationary.
