Suspension structure for an outboard motor
The granted patent US12071212B2 outlines a suspension structure specifically designed for outboard motors. This structure includes a clamp bracket for attachment to a hull, a main body support that is positioned lower than two defined positions when the motor is in a tilt-down state, and a coupling that allows for rotational movement about a tilt shaft. The main body support is strategically located between the first and second positions, which are aligned in the axial direction of the tilt shaft. When the outboard motor is tilted down, the main body support's position creates an imaginary triangle with the first and second positions as vertices. The design ensures that when thrust forces are applied parallel to the tilt shaft, compressive and tensile forces are effectively managed through the coupling.
Further claims detail the structural components and functionality of the suspension system. The first and second positions are specified to be spaced apart along the tilt shaft's axial direction. The main body support is designed to bear the weight of the outboard motor, and additional features include a held portion positioned higher than the main body support and a second coupling that allows for up-and-down movement. The coupling can be either unitary or consist of separate members connecting the main body support to the first and second positions. Overall, the patent presents a comprehensive framework for enhancing the stability and performance of outboard motors through its innovative suspension structure.
