Anti-locking brake system for a land vehicle

An anti-locking brake system for a land vehicle for traction control and vehicle dynamics control comprising:

• a pump for actuating a wheel brake, said pump removes brake fluid from a brake pressure generating unit and supplies it to the wheel brake;
• a first valve arrangement connectively disposed between the brake pressure generating unit and an input connection of the pump where, in a non-actuated normal position, blocks the connection between the brake pressure generating unit and the input connection of the pump and in at least one actuated position establishes a primary flow connection between the brake pressure generating unit through the pump to the wheel brake;
• a first electromagnetic valve arranged in a connection between an output connection of the pump and the brake pressure generating unit which, in a non-actuated normal position, establishes the connection between the output connection of the pump and the brake pressure generating unit and blocks the output connection in an actuated position;
• a second electromagnetic valve arranged in a direct connection to the wheel brake and is also connected to the wheel brake and the input connection of the pump which, in a non-actuated normal position blocks the connection between the wheel brake and the input connection of the pump and establishes the input connection in an actuated position;
• a third electromagnetic valve arranged in a connection between the output connection of the pump and the wheel brake which establishes the connection between the output connection of the pump and the wheel brake in a non-actuated position and blocks the output in an actuated position;
• wherein during a maintain pressure operating phase the first valve arrangement is in the non-actuated position, the first electromagnetic valve is in the actuated position, the second electromagnetic valve is in the non-actuated position, the third electromagnetic valve is in the actuated position;
• and
• wherein during a reduce pressure actuating phase the first valve arrangement is in the non-actuated position and the first, second and third electromagnetic valves are each in the actuated position, wherein the brake fluid flows only into the temporary store.

An anti-locking brake system for a land vehicle for traction control and vehicle dynamics control comprising:

• a pump for actuating a wheel brake, said pump removes brake fluid from a brake pressure generating unit and supplies it to the wheel brake, wherein
• a valve arrangement is disposed between the brake pressure generating unit and an input connection of the pump which is a 2-connection/3-position valve and blocks the connection between the brake pressure generating unit and the input connection of the pump in a non-actuated (normal) position;
• the valve arrangement establishes a secondary flow connection between the brake pressure generating unit and the input connection of the pump in a first actuating position;
• the valve arrangement establishes a primary flow connection directly between the brake pressure generating unit and the input connection of the pump in a second actuating position;
• and
• the primary flow connection has a larger flow cross section than the secondary flow connection.
