Hydraulic braking system

An external force-supported hydraulic braking system of a wheeled vehicle, comprising:

• two brake circuits each having a main brake line configured to be connected to a pressure-carrying supply line or to a pressureless return line via a brake valve, and further having a number of wheel brake lines branching from the main brake line and each leading to a wheel brake cylinder of a wheel brake, comprising a valve assembly of an ABS system which at each wheel brake has an inlet valve, with a check valve connected in parallel, arranged in the corresponding wheel brake line, and an outlet valve leading from the respective wheel brake cylinder into a return line, and comprising a valve assembly of a TCS system, by means of which a pressure line can be connected directly to the main brake lines and the return lines can be blocked,
• wherein the valve assembly of the TCS system has a single TCS control valve formed as a 6/2-way magnetic switching valve configured to, in a non-actuated state, block a pressure-carrying main pressure line against two bypass lines each leading directly to a respective main brake line and connect the two return lines to a pressureless collective line, and further configured to, in the actuated state, connect the main pressure line to the two bypass lines and block the two return lines against the collective line.
