Drive shaft mounted emergency brake

Abstract

An emergency braking system for a vehicle, said system being independent of the primary service braking system for the vehicle, wherein the system includes a first cone-shaped copper brake member mounted coaxially on the vehicle drive shaft for limited axial movement but is prevented from rotation by cooperation with a housing fixed to the vehicle chassis, and a second cone-shaped copper brake member fixed coaxially on the drive shaft for rotation with the drive shaft and telescopically received in the first brake member. A cable extends from the first brake member to the cabin of the vehicle so that the driver can move the first brake member axially into contact with the second brake member to slow or stop the vehicle. The first brake member is normally biased out of contact with the second brake member.

Dependencies are inferred from the claim text.
