Definitions

• the present invention relates to a caliper for a disc brake. It particularly relates to a caliper for a disc brake for a truck.
• the brake caliper has a Sate I frame designed to cover the brake disc and an enclosure for receiving an application mechanism for applying the disc brake.
• Such calipers usually have a saddle frame designed as a casting, which forms a cover of the housing and between the housing and an opposite thereto provided saddle back usually forms tension struts, which connect the saddle back with a mounting side end of the caliper, and a brake shoe abutment, which is supported, especially when braking on the saddle satges.
• a part of such a caliper is known, which is formed from two pieces of sheet metal, which bear against each other.
• the sheet metal pieces form a receptacle for a Zuspannelement the Zuspannmechanik and cylindrical recordings, which are fixed and floating bearings for holding a movable brake shoe.
• the usual today saddle frame are, however, designed as a casting, which is associated with various disadvantages. So cast components are very heavy. Casting with lost molds is uneconomical. The wall thickness is due to the process at greater than 10mm.
• the present invention is based on the problem to provide a Bremssattei, which can be produced more cost-effectively and then more economically and should have a lower weight.
• a brake caliper with the features of claim 1 is proposed by the present invention.

• the housing is bounded on the top side by a cover and unilaterally by a bottom segment.
• the enclosure should be substantially completely closed, in particular on the ground, in order to prevent the ingress of soiling and foreign bodies into the enclosure, as this may impair the application mechanics.

• the metal tubes are not necessarily closed circumferentially. Further, the sheet metal pipes are not necessarily provided inside the enclosure. Rather, the bearings are usually at the level of the housing and are essentially covered by the saddle frame, preferably the cover, but outside the housing for the Zuspanmechanik. As can be seen, the caliper according to the invention can then be made solely from semi-finished sheet metal.
• the bearings are not formed by forming one of the sheet metal elements, they are usually formed by deflected lengths, which are formed from prefabricated pipe semi-finished products. All sheet metal materials are preferably made of a good weldable material, so that the support and a bearing of the moving parts of a disc brake forming parts of the caliper can be firmly connected by welding to a unit. Since castings can be dispensed with in the manufacture of this frame, the caliper can be produced with a low weight.
• the use of metal sheets moreover allows the targeted selection of a material which has been hardened in a certain way by rolling and possibly heat treatment and which optimally meets the mechanical requirements which are placed on a brake caliper.
• the selected sheet material should, on the one hand, have a good strength but, on the other hand, also a good forming and / or bending workability.
• the saddle frame is formed by a uniform sheet metal element, which also forms a saddle back.
• the saddle frame usually forms that part of the caliper that forms the cover segment, the two tie rods and the saddle ends connecting the tie rods end together. Move back between the cover segment and the saddle is usually a space for receiving the brake disc
• this recess is dominated by the inner segment, which preferably forms a holder for at least one of the brake shoes.
• the inner and the outer segment and the ground segment are formed by a one-piece, formed sheet metal element.
• the outer segment and the inner segment are usually formed by edges around mutually parallel axes, so that the two segments extend parallel to each other at right angles to the ground segment.
• the bottom segment is usually bent up to at least one, regularly to both end sides in the direction of the cover segment to Form the enclosure laterally bounding walls.
• the outer and inner segments and the ground segment are usually connected to each other by welding together to first prepare the claimed after this development prefabricated component as a solid unit and later connect with other parts of the caliper.
• the seat back is formed integrally on the saddle frame, preferably on the cover segment.
• the saddle back is stiffened with a stiffening element that leaves a cavity between itself and the saddle back.
• the stiffening element usually forms the contact surface for one of the brake shoes, which is mounted on the saddle back.
• the saddle back or the stiffening element preferably carries a fastening element which serves to hold a brake pad retaining clip, which projects beyond the saddle frame and spans the brake disc.
• This fastener is usually butt welded.
