Heavy vehicle anti-overturning retarder - has centrifugal acceleration detector emitting signal to solenoid operated brake valve and alarm circuit

摘要

The anti-overturning retarder is for heavy road vehicles with a high centre of gravity, detecting the critical centrifugal acceleration on entering a curve and automatically acting on the vehicle brakes. It has a centrifigual acceleration detector (1) emitting an electrical signal, together with a solenoid valve receiving the signal and actuating the vehicle brakes at the same time as audible and visual signals, e.g. a buzzer and red stop lights at the rear. The detector can comprise sealed housing in which a steel ball (3) on the end of a pendulum arm works in a damping liq. (4).
