Abstract

A caliper of the disc brake is axially displaceable relative to a carrier, a bolt (6) being guided in a bore (4) of the caliper or the carrier and provided with a resilient guide element (8) seated in the bore. For the purpose of defining the radial movements of the bolt within the bore a stop element (28) is provided. In order to avoid contact between the stop element (28) and the guide bolt (6), the stop element (28) is integrated into the resilient guide element. As shown, stop element (28) is a metal ring in an annular groove (26) in a recess (24) on the outer periphery of element (8), and the outer diameter of stop element (28) over that of bore (4) is smaller by twice as much as the permitted deformation of guide element (8). <IMAGE>

Description

SPECIFICATION Spot-type disc brake This invention relates to spot-type disc brakes and in particular to a bolt guide for the caliper of a floating caliper spot-type disc brake of the kind comprising a brake carrier and a caliper axially displaceable thereto and embracing a brake disc and brake shoes, the brake carrier and the caliper including at least one bolt guided in a bore of the caliper and of the brake carrier, respectively, a resilient guide element for the bolt, seated in the bore, and a fixed stop element for defining radial movements of the bolt within the bore.
In a known bolt guide a stop element is provided which is located between two guide elements in the bore. If a resilient deformation of the guide elements is exceeded by a predetermined amount, the stop element will come into contact with the bolt.
It is an object of the invention to provide a bolt guide which avoids a contact between the stop element and the guide bolt.
According to the invention in its broadest aspect, a bolt guide for the caliper of a floating caliper spot-type disc brake is characterised in that the stop element is integrated into the resilient guide element.
The invention provides in simple manner a bolt guide in which the resilient path of deformation is limited to a maximum value and in which a contact between the stop element and bolt is avoided. Another advantage resides in that the stop element is arranged in a manner relatively protected against corrosion.
The construction of the conventional flexible guide elements will be largely maintained. As the stop element is integrated into the resilient guide element, this will also facilitate assembly thereof.
According to a preferred embodiment of the invention, the stop element is comprised of a metal ring, providing for a rotationally-symmetrical arrangement which has a uniform effect in all directions.
According to another embodiment the stop element is disposed on the outer periphery of the resilient guide element. The guide element has on its outer periphery a circumferential recess in which is provided an annular groove in which the stop element is located. The outer diameter of the stop element over that of the bore is smaller by twice as much as the permitted deformation of the resilient guide element.
As the stop element utilises only a part of the overall guide length of the guide element, the function of the resilient guide element will be fully maintained. However, in the event that the deformation of the guide element exceeds the permitted amount, the stop will come into contact with the surrounding bore wall, and the force from the "nick moment" causing the deformation, via the stop and the mass of the resilient guide element, will be transmitted between the latter and the bolt.
An embodiment of the invention will now be described by way of example with reference to the single figure of the accompanying drawings.
The drawing shows a partial longitudinal section through a bolt guide for the caliper of a floating caliper spot-type disc brake. Only the guide area is shown of caliper 2 of the disc brake; it includes a bore 4 provided in the direction of the path of movement of the caliper. The only part of the brake carrier shown is guide bolt 6 inside bore 4, with an annular space remaining between guide bolt 6 and bore 4 of the brake carrier 2, in which is disposed a resilient guide element 8.
The resilient guide element 8, generally, is in the form of a sleeve closed at one end.
Provided on the outer side of the guide element are two circumferential shoulders 10, 1 2 forming on the outer periphery a groove of substantially rectangular cross-section which is engaged by brake carrier 2. Guide element 8 is axially secured in brake carrier 2 in substantially undisplaceable manner by means of the shoulders 10, 1 2. Provided on the inner wall of guide element 8 are circumferential guide ribs 14, 16, 18 and 20 and a broader guide ridge 22. The guide element with the guide ribs and the guide ridge, respectively, is in abutment with the outer side of the guide bolt 6. Provided on the outer periphery of guide element 8, in the plane of the guide ridge, is a recess 24 in which is formed an annular groove 26 in which is seated a stop element 28 formed here as a metallic ring.The outer diameter of the stop element 28 relative to bore 4 is so dimensioned as to be smaller by twice as much as the permitted deformation of the guide element 8.
1. A bolt guide for the caliper of a floating caliper spot-type disc brake of the kind comprising a brake carrier and a caliper axially displaceable thereto and embracing a brake disc and brake shoes, the brake carrier and the caliper including at least one bolt guided in a bore of the caliper and brake carrier, respectively, a resilient guide element for the bolt, seated in the bore, and a fixed stop element for defining radial movements of the bolt within the bore, characterised in that the stop element (28) is integrated into the resilient guide element (8).
2. A bolt guide according to claim 1, characterised in that the stop element (28) is a metal ring.
3. A bolt guide according to claim 1 or 2, characterised in that the stop element (28) is disposed on the outer periphery of the resilient guide element (8).
