Pneumatically actuable disc brake

摘要

A pneumatic disc brake has a caliper which straddles a brake disc, brake pads pressable against the brake disc, wherein a brake-application-side brake pad can be actuated by a brake lever of a brake application device pivotable about an eccentric axis. Against the end side, the brake lever bears a brake ram which is coupled at the other side to the brake pad or to a guide plate coupled thereto. Two pressure rams are aligned in the same direction and spaced apart from the brake ram. The pressure rams are connected in each case to the caliper and to the brake pad or to the guide plate and have a self-energizing device. The caliper has spherical-cap-shaped bearing receptacles in which rest corresponding plain bearing elements, by which the brake lever, and the pressure rams are supported on the caliper.

主权项

1. A pneumatic disc brake for use with a brake disc, comprising:
a caliper for straddling the brake disc, the caliper comprising spherical cap-shaped bearing receptacles in an interior thereof; a brake application device arranged in the caliper, the brake application device having a brake lever pivotable about an eccentric axis against a brake ram for displacing a brake application side brake pad against the brake disc; two pressure rams aligned with the brake ram and spaced apart from the brake ram; a self-energizing mechanism operatively configured with respect to the two pressure rams; plain bearing elements adapted to engage in the spherical cap-shaped bearing receptacles, the spherical cap-shaped bearing receptacles and plain bearing elements supporting the brake lever and the two pressure rams on the caliper on a side of the brake lever and the two pressure rams that faces away from the brake disc, wherein a snap connection is provided between the brake ram and the brake pad.
