Road vehicle severe braking warning device - has pressure sensor in brake fluid circuit to close circuit of additional braking lights at preset pressure level

摘要

The hydraulic equipment has a third cylinder (2) and a pedal (3) to operate brakes (5 - 8) on the wheels (9 - 12). Pressure on the pedal closes a switch (13) in a circuit (14) joining one battery (16) terminal (15) to lamps (18). There is also a pressure sensor (20) for brake fluid. This closes a circuit (21) when a present pressure level is reached. The circuit (21) joins the terminal (15) of the battery to a terminal (22) of two lamps (23) each near the lamps (18). The effect is that with a normal application one set of lamps light and with severe braking both sets light, so warning following vehicles.
