Abstract
In an electropneumatic brake system for a towed vehicle having at least two axles, such as a drawbar trailer, one axle is assigned a first modulator at least with an anti-lock function and another axle is assigned a second modulator at least with an anti-lock function and an additional function. Both modulators are connected to a reservoir pressure, and both modulators load wheel brake cylinders via brake pressure lines. The second modulator is connected to a control line and the first modulator has a connector for a control line. A control line leads from the connector for the control line on the first modulator to the brake pressure line between the second modulator and at least one of its wheel brake cylinders.
Claims8
An electropneumatic brake system for a towed vehicle having at least two axles, the brake system comprising first and second modulators, the first modulator being assigned to one of the at least two axles and operable to effect at least an anti-lock function, the second modulator being assigned to another of the at least two axles and operable to effect at least an anti-lock function and an additional function, the first and second modulators being connected to a reservoir pressure and configured to load wheel brake cylinders via brake pressure lines, the second modulator being connected to a second control line, and the first modulator being connected via a connector to a first control line leading to the one of the brake pressure lines between the second modulator and at least one wheel brake cylinder of the second modulator.
