Abstract: The invention relates to a floating-caliper disc brake of a motor vehicle including a brake holder firmly attached to the vehicle and a floating caliper that is mounted on the brake holder so as to be axially displaceable. In this arrangement, the floating caliper is displaceably mounted on the brake holder, preferably by means of at least one pin guide. A radial fixation of the floating caliper on the brake holder is carried out by a locking element that is detachably secured to the floating caliper and with a portion is axially displaceably arranged on the brake holder. To improve ease of displacement of the floating caliper and to prevent undesirable radial movements of the floating caliper, the locking element is secured to the floating caliper so as to be adjustable in its radial position. As a result, it is possible to adjust a defined radial clearance between the floating caliper and the brake holder.

Abstract: The present invention relates to a spot-type disc brake with a brake housing straddling a brake disc, with at least one brake pad that is arranged in the brake housing so as to be slidable in the actuating direction and cooperates tribologically with the brake disc upon brake application, with at least one actuating device arranged in the brake housing to apply an actuating force to the brake pad, and with a spring assembly for the active adjustment of a clearance between the brake pad and the brake disc after brake application. To simplify the configuration of the spring assembly, the spring assembly comprises exactly one spring which is secured detachably in the spot-type disc brake and is supported on the brake pad and on the brake housing. A spring of this type is arranged advantageously symmetrically within the brake housing to prevent an undesirable inclined positioning of the brake pads.

Abstract: A disc brake for automotive vehicles in which the brake disc is straddled radially from the inside by a fist-shaped brake housing. The supporting and guide elements of the housing consist of a supporting bearing (34) and a movable bearing (7). The supporting bearing (34) connects the housing (8) with the holder (6). The housing 8 is swivelable about the supporting bearing (34). The housing (8) takes support on the movable bearing (7) which comprises a pin (3) rigidly coupled directly to the wheel suspension (38). By coupling the movable bearing (7) directly to the wheel suspension and supporting the lining in a tangential direction directly on the entering side, maximum utilization of the radial space, an increase of the effective radius, and a reduction of the thermal load of the brake are achieved.

Abstract: A spot-type disc brake in which a brake carrier elastically mounts a brake frame on a pair of guide rods so as to allow limited axial tilting. The brake carrier has a pair of axial arms receiving the brake pads therebetween and each attached to a radial member facing an inner connecting member connecting brake frame arms, and the guide rods extending axially therebetween. The brake frame arms straddle the carrier arms, and a spring element acts to press a contact area on one connecting portion of the carrier arms into engagement with central area on an outer connecting member fixed between the brake frame arms. A space between a pair of radially extending limbs of the brake carrier receives the actuating device mounted on another connecting member extending between the brake frame arms. Guide pins fixed to the brake carrier extend through oblong openings in the brake pads.

The brake lining is connected to the arms in a positive locking fit in the direction of the circumference of the brake disc in such a manner that the frictional force occurring at the brake lining is transmitted to both arms at least in the presence of more elevated brake application forces. The arms with surfaces facing each other form a guide which is open in radially outward direction and serves to accommodate and guide the brake shoe. One arm in the vicinity of the brake disc is formed with a groove extending in the direction of brake application and is open outwardly.
