Disc brake

摘要

A disc brake includes a brake caliper, in which two brake pads can be pressed against a brake disc when in operation. A brake pad on the action side is actuatable via a brake plunger of a brake application device. The brake plunger is led through an opening of a closure cover that closes a receiving chamber of the brake caliper. A bellows rests against the brake plunger and, on the other side, against the closure cover to seal the receiving chamber. A secondary seal is retained on the closure cover, which secondary seal is arranged concentrically to the bellows and rests against the brake plunger. The secondary seal is configured to rest slidingly against the brake plunger.

主权项

1. A disc brake for use with a brake disc, comprising:
a brake caliper in which are arrangeable two brake pads that are pressed against the brake disc in use, the caliper comprising a receiving chamber; a brake application device having at least one brake plunger by which an action-side of one of the two brake pads is actuatable; a closure cover configured to close off the receiving chamber of the caliper, wherein the brake plunger is guided through an opening of the closure cover and the closure cover having an essentially planar surface facing the action-side one of the two brake pads in regions away from the closure cover opening; a corrugated bellows configured to seal-off the receiving chamber, one end of the corrugated bellows bearing against the brake plunger and another end against a first side of the closure cover without extending beyond the essentially planar closure cover surface toward the receiving chamber; and a secondary seal held on an opposite second side of the closure cover without extending to the first side of the closure cover, the secondary seal being arranged concentrically with respect to the corrugated bellows, wherein the secondary seal bears slidingly against the brake plunger.
