Publication number: 20240010298Abstract: A flexible coupling mechanism may be used to suspend a structural component, such as a propulsion pod, from a support member, such as a strut of a hydrofoil watercraft. The flexible coupling mechanism may include multiple vibration isolating mounts configured to extend through the support member to suspend the structural component. The vibration isolating mounts may include a plurality of elastomeric bushings configured to prevent direct contact between a component rigidly coupled to the support member and a component rigidly coupled to the structural component. The elastomeric bushings may include a tapered outer profile configured to provide a nonlinear force feedback profile in response to rotation of the support member relative to the structural component.Type: ApplicationFiled: September 21, 2023Publication date: January 11, 2024Inventors: Donald Lewis Montague, Joseph Andrew Brock, Tomasz Pawel Bartczak, Matthew Campbell Greaves, Alec Korver, Jamieson Edward Schulte, Dmitri Stepanov

Publication number: 20230398855Abstract: A wheel assembly for an electrical vehicle. The wheel assembly comprising a hub integral with an electrical motor, and a fluid actuated fail-safe brake fitted to the assembly with at least one braking surface for frictional engagement with the rotor of the electrical motor. The brake in its non-actuated state is engaged with the rotor, and when fluidally actuated the brake is released to allow rotation of the rotor. A solenoid valve having a normally open state is in fluid communication with the pressurised fluid used to fluidally actuate the brake, and the solenoid valve is a closed when electrically powered thereby allowing fluid actuation to release the brake. In the event of a loss of electrical power the solenoid valve will revert to the normally open state, so that the brake is non-actuated and applies a braking force to the rotor.Type: ApplicationFiled: October 21, 2021Publication date: December 14, 2023Inventors: Julian BROADBENT, Nicholas FARMER, Matthew Campbell GREAVES
