Abstract

A spot-type disc brake with a floating-caliper comprises a brake support member and a brake caliper that is arranged at the wheel axle in a manner slidable parallel to the brake disc axis by a single guide element (5,6) includes brake shoes which are replaceable tangentially relative to the brake disc. The brake support member is constructed in the shape of a retaining element which is arranged on one side of the brake disc parallel to the disc and which may be constructed integrally with the wheel axle. The brake shoes are retained either on the disc entry side in the brake caliper (2) or on the disc exit side at the brake support member (1) or in the brake caliper by retaining elements. On the side opposite to the retaining elements, i.e. on the disc entry side or on the disc exit side, the brake shoes are supported in the brake caliper.

Claims

1. A spot-type disc brake comprising a brake support member disposed on one side of and parallel to a brake disc,

a brake caliper embracing the edge of said brake disc, said caliper having an arm having a first opening through which a bushing passes to slidably mount said caliper to said support, said caliper having a second opening on a disc entrance side thereof with respect to a main direction of rotation of said disc, a pin received in the second opening in the caliper and extending parallel to a rotational axis of said brake disc,

a pair of brake shoes each disposed on a different side of said brake disc and each including a pad carrier and a friction pad fastened to the carrier, each of said pad carriers having an opening at said disc entrance side thereof through which said pin passes, each of said pad carriers also having a suspension tab extending from a disc exit side thereof, said caliper having a complementary guide edge against each suspension tab of said pad carriers abut,

whereby said pad carriers are slidably supported in said caliper for movement parallel to the rotational axis of said brake disc.

2. The disc brake of claim 1 wherein an edge section of each pad carrier adjacent said pin opening abuts a complementary support surface on said caliper.

3. A spot-type disc brake comprising a brake support member disposed on one side of and parallel to a brake disc

a brake caliper embracing the edge of said brake disc, said caliper having an arm having a first opening through which a bushing passes to slidably mount said caliper to said support, said caliper having a second opening on a disc exit side thereof with respect to a main direction of rotation of said disc, a pin received in the second opening in the caliper and extending parallel to a rotational axis of said brake disc,

a pair of brake shoes each disposed on a different side of said brake disc and each including a pad carrier and a friction pad fastened to the carrier, each of said pad carriers having an opening at said disc exit side thereof through which said pin passes, each of said pad carriers also having a suspension tab extending from a disc exit side thereof, said caliper having a complementary guide edge against each suspension tab of said pad carriers, abut,

whereby said pad carriers are slidably supported in said caliper for movement parallel to the rotational axis of said brake disc.
