Introduction

Roy Campbell, an industrious inventor from Worcestershire, GB, is recognized for his contributions to the field of automotive braking systems. With an impressive portfolio of 21 patents, Campbell's work demonstrates remarkable innovation in enhancing vehicle safety and efficiency.

Latest Patents

Among his latest patents are groundbreaking designs for self-energizing disc brakes. This innovative compound disc brake includes a pair of pressure plates featuring a sophisticated ball and ramp camming mechanism. One of these plates is a driven plate, securely keyed to a rotating axle shaft, while the other acts as an input plate mounted via the camming mechanism. The input plate boasts a larger diameter and contains a torque-transmitting mechanism that effectively conveys torque from the primary braking device to the central region of the input plate. The resultant braking system ensures a swift and effective separation of the pressure plates for optimal engagement with stationary braking surfaces.

Additionally, he has developed vehicle disc brakes of the liquid-cooled type. The design incorporates a rotatable member with annular braking faces and a series of angularly spaced liquid supply slots. These slots emanate from a position within the disc, facilitating enhanced cooling and performance during braking. Some embodiments of this invention serve dual purposes, acting either as a braking member or as a turbo disc pump member.
