Title: Innovator Michel Grenier: Pioneering Vehicle Braking Systems

Introduction

Michel Grenier, an inventive mind based in Dampmart, France, has made remarkable contributions to the field of vehicle braking systems, earning a total of five patents throughout his career. His innovative designs focus on enhancing safety and efficiency in braking mechanisms, particularly for railroad vehicles.

Latest Patents

One of Grenier's latest patents includes a **Vehicle Park Braking System**, which features a disk brake mechanically connected to at least one wheel of the vehicle. This system utilizes a brake caliper actuated by a threaded rod, ensuring that the threaded connection is irreversible by axial forces alone. Notably, the brake linings are made from an elastomeric material that exhibits a high friction coefficient when the disk is stationary. This design provides a compact parking brake with significant power and remote indication capabilities, making it especially advantageous for railroad vehicles.

Another notable invention is the **Spring Brake Unit and its Application to a Braking System**. This invention consists of a braking unit characterized by an axial actuating helical spring maintained in the release position through a screw-nut system, which is driven by an electric motor. The unit operates by having the spring exert force on the brake with the assistance of a hydraulic master cylinder, thereby integrating a spring braking system for vehicles, which can include a built-in park brake.

Career Highlights

Throughout his career, Michel Grenier has had the opportunity to work with esteemed companies such as Wabco Westinghouse and Wabco Westinghouse Equipements Ferroviaires. His experiences at these organizations have undoubtedly enriched his understanding of vehicle brake technologies and systems, facilitating the development of his innovative patents.

Collaborations
