AI Technical Summary

Technical Problem

Existing braking systems for rail vehicles, particularly track-laying machines, suffer from high wear due to friction-based braking, risk of overheating, and inefficiency in energy dissipation, especially on steep gradients, without adequate consideration for rotational mass components.

Method used

A modular braking device that converts translational energy into various forms such as mechanical, electrical, or thermal energy, utilizing a fluid system for energy recuperation, and includes a transformer and current collector to feed back electrical energy into a trackside supply or store it in a vehicle-side storage, reducing wear and overheating risks.

Benefits of technology

The modular braking device reduces wear on friction brakes, minimizes overheating, and enhances energy efficiency by recycling kinetic energy, saving weight and costs while maintaining effective braking performance.
