Disc Brake, Brake Actuation Mechanism For Such A Disc Brake And Method For Brake Adjustment

摘要

A disc brake including a brake actuation mechanism and an adjustment mechanism, which is configured to provide, in addition to a reduction of the clearance between a brake pad and a brake disc during brake application, a further increase of the clearance during brake release motion with a value, which may be smaller, equal or larger than the previous clearance reduction. The brake actuation mechanism for that purpose could provide a different regulator unit. Moreover, the invention suggests a method for adjusting the clearance between a brake pad and a brake disc providing a clearance increase during brake release motion, accordingly.

主权项

1. A disc brake comprising a brake caliper, which straddles at least one brake disc, and a brake actuation mechanism comprising:
an amplification mechanism for introducing a clamping force, a thrust element for transmitting the clamping force via a brake pad onto the brake disc, in which, at the release state of the disc brake, a clearance is set between said brake pad and the brake disc, an adjustment mechanism for compensation of wear of said brake pad and/or said brake disc during brake actuation, the adjustment mechanism being configured to act on said thrust element and comprising a first regulator unit being configured to reduce said clearance between the brake disc and the brake pad during brake actuation motion, characterized by a second regulator unit being configured to, during brake release motion, increase said clearance with a value, which may be smaller, equal or larger than the clearance reduction.
