Hand Brake Valve For Braking Systems Of Pneumatically Braked Motor Vehicles

摘要

A hand brake valve (1) for braking systems of pneumatically braked motor vehicles includes a rocking lever (2) pivotably guided in a lever housing (4) and connected to a control element (9, 10) for actuating the hand brake valve mechanism (7), the rocking lever bears a shift handle (3) and is configured to be pivoted into different operating positions guided in a shift gate (13), wherein the rocking lever comprises a locking element (12) that cooperates with the shift gate and that slides along a curved sliding path (15) of the shift gate, wherein a locking groove (16) is radially formed in the curved sliding path (15), the locking element being snapped into said locking groove in the locked position, and wherein the hand brake valve comprises an electrical switching element (22) configured to be actuated exclusively in the locked position.

1. A hand brake valve (1) for braking systems of pneumatically braked motor vehicles, comprising:
a rocking lever (2) pivotably guided in a lever housing (4) and connected to a control element (9, 10) for actuating a hand brake valve mechanism (7), the rocking lever bears a shift handle and is configured to be pivoted into different operating positions by being guided in a shift gate (13), wherein the rocking lever (2) comprises a locking element (12) that cooperates with the shift gate (13) and that slides along a curved sliding path (15) of the shift gate (13), wherein a locking groove (16) with groove walls (17, 18) and a groove base (19) is radially formed in the curved sliding path (15), the locking element (12) being snapped into said locking groove in a locked position, and wherein the hand brake valve (1) comprises an electrical switching element (22) configured to be actuated exclusively in the locked position of the locking element (12) in the locking groove (16), and wherein an actuating member (28) of the electrical switching element (22) is arranged at least partially in the locking groove (16) and radially above the groove base (19) and is configured to be directly actuated by the locking element (12).
