AI Technical Summary

Technical Problem

Existing braking systems in vehicles, such as anti-lock braking systems (ABS) and electronic stability programs (ESP), are limited in their effectiveness and require precise timing, and cannot be reused once activated, while flywheel energy storage devices in hybrid vehicles do not effectively increase wheel contact force during braking or acceleration.

Method used

A flywheel energy storage device with a pivotable rotational axis is used to increase wheel contact force by pivoting the axis of rotation, leveraging the gyroscope's resistance to maintain its position, generating a counterforce that enhances braking or acceleration forces.

Benefits of technology

The solution increases wheel contact force, shortening braking distance and reducing collision speed, particularly during straight-line braking, and improves safety by enhancing braking and acceleration forces, especially when combined with ESP systems.

Abstract

Device (20) for operating a vehicle (1), in particular a motor vehicle, which has at least two wheel axles (2, 3) each with two wheels (4, 5; 6, 7), and a braking device (9) for braking the wheels (4, 5; 6, 7) of the two wheel axles (2, 3), wherein the device has a flywheel energy storage device (10) comprising at least one flywheel (11) and a bearing device rotatably mounted the flywheel (11) about an axis of rotation (13), wherein the bearing device has means for pivoting the axis of rotation (13), characterized in that the device (20) is designed to pivot the axis of rotation (13) of the bearing device to the rear when the braking device (9) is activated, so that a wheel contact force of the wheels (4, 5; 6, 7) of the wheel axle (2, 3) located at the front in the direction of travel of the vehicle (1) is increased.
