Twin-type load-sensitive brake force reducing valves

To achieve the best possible adjustment of braking forces to the widest range of vehicle load conditions, a load-sensitive brake force reducing valve is used to regulate the hydraulic pressure on the rear wheel brakes. For vehicles with diagonal brake circuit split, either two individual proportioning valves or one valve with two control units for the rear wheel brakes is used.

In the new Twin regulators, two identical control units operating independently of each other are placed parallel to each other in one housing. A spring load is applied to them by means of a common lever. This permits regulating the two brake circuits to the rear axle separately from each other. If one circuit fails, the remaining intact brake circuit can continue to operate without being influenced by the failure.

The basis for our development work in the field of brake force regulation, are lightweight brake force proportioning valves designed in a modular system. Compared with conventional regulators these regulators have the following advantages:

• ATE utilizes its technologies as a world market leader in the brake field to manufacture OE quality brake force reducing valves.
• Weight cut by around 50 % due to use of extruded aluminum sections.
• Compact design, little installation space required.
• Mechanical or hydraulic activation of load-sensitive brake force reducing valve possible.
• Modular system, the same regulating cell design for all regulator types.
• Stainless steel and aluminum protect them against corrosion.
