INTERNAL EXPANDING SHOE BRAKE, IN PARTICULAR WEDGE-ACTUATED SIMPLEX BRAKE, WITH AN ACTUATOR FOR EXPANDING BRAKE SHOES |
摘要 |
An internal expanding shoe brake comprises expansion pistons (17) for forcing opposing brake shoes (2) apart. In each expansion piston (17) one adjusting pin (30) is axially movably arranged and presses against a brake shoe web (4) by means of a pressure piece (34). Said pressure piece (34) is supported on the adjusting pin by means of a ball joint so as to pivot in any direction. In order to prevent the adjusting pin (30) from being twisted inside the expansion piston (17), an anti-rotation element is provided and comprises a pressure piece projection (39) which projects over the ball joint surface (36) of the pressure piece (34), said projection interlockingly engaging in a receiving opening (40) of the adjusting pin (30) with lateral play and forming a rotational coupling connection. |
