Title: Innovations of Hans-Joachim Schulz

Introduction

Hans-Joachim Schulz is a notable inventor based in Wedemark, Germany. He has made significant contributions to the field of vehicle braking systems, holding a total of three patents. His work focuses on enhancing the safety and efficiency of trailer braking mechanisms in tractor-trailer vehicles.

Latest Patents

One of his latest patents is a trailer control valve device for the trailer brakes of a tractor-trailer. This invention involves a brake pressure control valve that regulates the braking pressure in the trailer brake system. It allows the trailer brake pressure to develop to a preset level ahead of the braking pressure in the tractor brake system during a pilot phase of brake operation. The preset level can be adjusted using a member that is part of the auxiliary valving, which controls when the pilot phase of operation ends. Additionally, a limit stop is arranged with this adjustable member to prevent the advance trailer brake pressure from exceeding a specified safe maximum value.

Another significant patent is an apparatus for the control of brake pressure in a trailer pulled by a tractor. This apparatus features a two-circuit controllable relay valve as the trailer control valve. The first circuit is controlled by the brake valve of the tractor, while the second circuit can be connected to a distribution valve with a pressure medium source. The activation of the distribution valve is controlled to ensure that the second circuit connects with the pressure medium source before or at the beginning of the activation of the first circuit. This innovation allows for the trailer's brake pressure to be increased prior to the tractor's brake pressure, enhancing overall braking performance.
