Description
Technical Field
The utility model relates to a disc brake, especially the disc brake pincers body based on wedge auto-lock clamp plate fixed mode.
Background
The disc brake has the advantages of good high-temperature resistance under high load, stable braking effect and better suitability for braking under severe road conditions, so national regulations actively promote the application of the disc brake in commercial vehicles and tend to replace drum brakes. The pressure plate is a part for fixing and keeping the friction plate in the disc brake, and the pressure plate is required to be fixed reliably and convenient to maintain and disassemble.
At present, the domestic disc brake pressure plate fixing structure is as follows: firstly, drilling a tangential hole on a clamp body, fixing a pressure plate by using a shaft pin, and preventing the shaft pin from falling off by using a split pin; and secondly, a radial threaded hole is processed on the clamp body, the pressing plate is fixed by a bolt, and the bolt is prevented from loosening by a thread fastening glue. The two structures need to process mounting holes on the clamp body, and the holes are positioned in the tangential direction and the radial direction of the circular arc of the clamp body, so that the processing of the holes needs a machine tool to be provided with a fifth shaft or is completed on two devices in two processes. The equipment investment is large, and the processing efficiency is low.
Disclosure of Invention
The utility model aims at providing a disc brake pincers body based on wedge auto-lock clamp plate fixed mode utilizes the wedge to eliminate the clearance between pincers body boss and the clamp plate to reach the purpose of fixed clamp plate, and prevent not hard up of clamp plate through the auto-lock power on wedge inclined plane.
Therefore, the technical scheme of the utility model is that: disc brake caliper body based on wedge auto-lock clamp plate fixed mode, including disc brake caliper body, clamp plate, the one end of disc brake caliper body is equipped with clamp plate slot, its characterized in that: the disc brake caliper further comprises a wedge-shaped stop block and a screw, a rectangular boss with a positioning groove is cast at the other end, opposite to the pressure plate slot, of the disc brake caliper body, and a rectangular hole is formed in the pressure plate; during clamp plate slot was inserted to clamp plate one end, the rectangular hole cover of clamp plate was on the rectangle boss, and the rectangular hole outside card of clamp plate was on the constant head tank of rectangle boss, and wedge dog was put into the space between the rectangular hole of clamp plate and the rectangle boss from below, and screw and wedge dog threaded connection, the lower part terminal surface roof pressure of screw were on disc brake pincers body, utilized the inclined plane of wedge dog to eliminate the clearance between rectangle boss and the clamp plate.
The technical scheme is limited as follows: the wedge dog corresponds to 2 lateral walls of clamp plate length direction, and one of them lateral wall has the inclined plane, and another lateral wall is vertical, and this kind of structure setting has simplified the structure when reaching the purpose only to one processing inclined plane of wedge dog, has reduced the processing cost.
The utility model has the advantages that: the utility model adopts reasonable structure, eliminates the clearance between the rectangular boss and the pressing plate by the inclined plane of the wedge-shaped block, thereby achieving the purpose of fixing the pressing plate and preventing the wedge-shaped block from loosening by the self-locking force of the inclined plane; the clamp body is provided with the pressing plate without additional processing, so that the processing cost is reduced.

Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1-3, the disc brake caliper body based on the wedge-shaped self-locking pressure plate fixing mode comprises a disc brake caliper body 1, a pressure plate 2, a wedge-shaped stop block 3 and a screw 4, wherein one end of the disc brake caliper body 1 is provided with a pressure plate slot 1-1, the other end of the disc brake caliper body, which is opposite to the pressure plate slot, is cast with a rectangular boss 1-2 with a positioning groove 1-2-1, and the pressure plate 2 is provided with a rectangular hole 2-1; one end of a pressing plate 2 is inserted into a pressing plate slot 1-2-1, a rectangular hole 2-1 of the pressing plate is sleeved on a rectangular boss 1-2, the outer side of the rectangular hole 2-1 of the pressing plate is clamped on a positioning groove 1-2-1 of the rectangular boss, a wedge-shaped stop block 3 is placed into a gap between the rectangular hole 2-1 of the pressing plate and the rectangular boss 1-2 from the lower side, a screw 4 is in threaded connection with the wedge-shaped stop block, the lower end face of the screw 4 is propped against a disc brake caliper body 1, and the gap between the rectangular boss and the pressing plate is eliminated by utilizing the inclined face of the wedge-shaped.
As shown in fig. 4, one structure of the wedge block 3 is: the wedge-shaped stop block is provided with a threaded hole 3-1, the wedge-shaped stop block corresponds to 2 side walls in the length direction of the pressing plate, one side wall 3-2 is provided with an inclined plane, the other side wall 3-3 is vertical, and the structure is only used for processing one inclined plane of the wedge-shaped stop block 3, so that the structure is simplified and the processing cost is reduced while the purpose is achieved.
For those skilled in the art, simple combination, equivalent replacement, and further improvement without departing from the technical concept of the present invention shall be included in the protection scope of the present invention.
