Title: The Innovative Contributions of Alain Landrot

Introduction

Alain Landrot is a notable inventor based in Le Creusot, France, recognized for his significant contributions to engineering and design. With a total of six patents to his name, Landrot has made strides in the field of transportation technology, particularly in the development of safety mechanisms for bogies in subway systems.

Latest Patents

One of Landrot's latest patents is a flexible connection device between a bogey side beam and an axle-box. This innovative device is designed to be placed between a flexible side beam of a bogey frame and an arm of an axle-box. The unique feature of this invention is that the stiffness of the connection is greater in the vertical direction than in the horizontal directions. This design allows for the decoupling of the side beam from the axle-box, which reduces stress at the interfaces during transverse and vertical movements of the bogey frame. Additionally, it permits relative displacements between the side beam and the axle-box.

Another significant patent by Landrot is for a safety wheel, which is intended for use in subway coach bogies running on pneumatic tires. This safety wheel is strategically positioned between the chassis of the bogie and the corresponding tire. It features an outer peripheral zone that includes both a braking portion and a guiding portion, with the braking portion being significantly harder than the guiding portion. This is achieved through selective tempering of the braking portion using cooling liquid from peripheral nozzles. The result is a safety wheel that boasts a considerably longer lifespan compared to those found in prior art.
