AI Technical Summary

Benefits of technology

This configuration provides a compact, lightweight suspension system that allows independent damping of each wheel, maintaining vehicle balance and comfort by isolating road bumps and potholes without affecting other wheels, while potentially reducing vehicle weight and enhancing traction.

Problems solved by technology

There are several examples of in-wheel suspension systems which require complicated connections to the vehicles' chassis or the use of an expensive electrical suspension system in connection to an electrical motor.
Such systems cannot be implemented to every vehicle.

Embodiment Construction

[0041]In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to obscure the present invention.

[0042]Aspects of the invention may be related to an in-wheel suspension system that may include three arms in a Watt's linkage configuration all been assembled inside an inner rim of a wheel. Such a suspension system may be compact, light-weight and may further allow the damping of each wheel separately, such that a bump or pothole in a road under one wheel may not affect at all any one of the other suspension systems of the other wheels. The in-wheel suspension system according to some embodiments of the invention may further include a shock absorbing unit for da...

Abstract

An in-wheel suspension system includes an assembly with a main arm that is pivotally connected at a connection point on the main arm to a shaft point of a wheel, a first linkage unit pivotally connected at one end to a first end of the main arm, and a second linkage unit pivotally connected at one end to a second end of the main arm. At least one second end of the first linkage unit and at least one second end of the second linkage unit, that are not connected to the main arm, are pivotally connectable each to a reference frame at a defined distance between them, such as to form a substantially “Z” like shape.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The invention generally relates to suspension systems for vehicles, and more particularly to in-wheel suspension systems for vehicles.BACKGROUND OF THE INVENTION[0002]Suspension systems are the systems configured to suspend a vehicle chassis above its wheels, to maintain good grip on the road while isolating the vehicle systems from road shocks and impacts. These can be contradicting demands that require compromising. Commonly used suspension systems, either rear or front, include: springs, shock absorbers and the linkages between to the vehicle's chassis and the wheels, all of which are external to the wheels.[0003]In-wheel suspension systems have several advantages as well as challenges that must be overcome. Such suspension systems can reduce the weight of the vehicle and allow flexible damping of each wheel separately. There are several examples of in-wheel suspension systems which require complicated connections to the vehicles' chassis or ...
