Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0025] Reference Figure 1-Figure 5 A high-stability front brake caliper for automobiles, comprising a bracket 1 and two sets of friction components, the left and right side walls of the bracket 1 are respectively provided with a hydraulic mechanism and a claw, the two sets of friction components are respectively connected to the hydraulic mechanism and the claw through a plurality of bolts 6, the hydraulic mechanism comprises two hydraulic cylinders 2 fixedly mounted on the side wall of the bracket 1, the claw comprises a plurality of blocking columns 3 fixedly mounted on the side wall of the bracket 1, the friction component comprises a friction plate 4 and a steel back 5, the friction plate 4 and the steel back 5 are fixedly connected;

[0026] The driving shaft end of the hydraulic cylinder 2 and the surfaces of the blocking columns 3 on both sides are provided with threaded grooves, the surface of the steel back 5 is provided with a threaded opening 7, the surface of the friction plate 4 is provided with a plurality of through openings 8 respectively connected with the plurality of threaded openings 7, the left and right side walls of the friction plate 4 are provided with mounting grooves 9, the groove wall of the mounting groove 9 is provided with a through opening connected with the through opening 8, a locking rod 10 is slidably inserted in the through opening, the locking rod 10 is connected to the friction plate 4 through a telescopic component, the telescopic component includes a telescopic spring 12 sleeved on the locking rod 10, one end of the locking rod 10 is fixedly installed with a mounting block, the two ends of the telescopic spring 12 are respectively fixedly connected with the groove wall of the mounting groove 9 and the surface of the mounting block, and the side wall of the end with a larger diameter of the bolt 6 is circumferentially provided with a plurality of locking grooves 11 for inserting the ends of the locking rod 10;

[0027] When installing the friction assembly, first control the locking rod 10 to move in a direction away from the friction plate 4 until the end of the locking rod 10 moves out of the through opening 8. At this time, align the threaded openings 7 on the surface of the steel back 5 with the multiple threaded grooves, and then insert the multiple bolts 6 from the multiple through openings 8 respectively, and threadedly install them in the threaded openings 7 and the threaded grooves until the larger end of the bolt 6 abuts against the through opening 8. The installation of the friction assembly can be completed, and the side wall of the larger end of the bolt 6 will correspond to the position of the locking rod 10. At this time, release the locking rod 10, and the end of the locking rod 10 will quickly move and reset under the elastic potential energy of the telescopic spring 12, and insert it into the locking groove 11 corresponding to its own position, thereby locking the bolt 6 and limiting the rotation of the bolt 6, thereby improving stability and eliminating the safety hazard of loosening of the connection due to the rotation of the bolt 6. When the friction assembly needs to be disassembled, it is necessary to first control the end of the locking rod 10 to move out of the locking groove 11, and after releasing the lock on the bolt 6, rotate the bolt 6 to move it out of the threaded groove and the threaded opening 7.

[0028] A U-shaped handle 13 is fixedly mounted on the surface of the mounting block. The surface of the handle 13 is provided with anti-skid patterns. The handle 13 is convenient for controlling the movement of the locking rod 10 , and the anti-skid patterns can increase the friction between the palm and the contact surface of the handle 13 .

[0029] The end surface of the bolt 6 with a larger diameter is provided with a socket, and a hollow rod 14 with a closed end is inserted into the socket. The hollow rod 14 is connected to the bolt 6 through a mounting component, and the mounting component includes a telescopic rod 19 fixedly mounted on the end surface of the bolt 6 with a larger diameter and a mounting ring 20 fixedly sleeved on the hollow rod 14. The outer ring wall of the mounting ring 20 is fixedly connected to one end of the telescopic rod 19 through a connecting rod. The end of the hollow rod 14 with an open end is fixedly installed with a suction cup 15. The surface of the hollow rod 14 is provided with a There is an air inlet 16, and a rotating port is opened at one end of the hollow rod 14 which is closed, and a rotating shaft 17 is installed in the rotating port for sealing and rotation. A cover 18 for covering the air inlet 16 is fixedly installed at one end of the rotating shaft 17 located in the hollow rod 14 through a connecting rod. The rotating shaft 17 is connected to the hollow rod 14 through an elastic component, and a rotating disk is fixedly installed at one end of the rotating shaft 17 located outside. The elastic component includes a torsion spring 21 sleeved on the rotating shaft 17, and the two ends of the torsion spring 21 are respectively fixedly connected to the rotating disk and the hollow rod 14;

[0030] When the bolt 6 rotates to abut against the through-port 8, the suction cup 15 can be controlled to move and abut against the wall of the through-port 8 by pressing the telescopic rod 19. Since the air inlet 16 is covered by the cover 18, when the suction cup 15 abuts against the through-port 8, the gas in the hollow rod 14 will slip out from the gap between the contact surface of the suction cup 15 and the through-port 8, so that the suction cup 15 will be attracted to the wall of the through-port 8, thereby further limiting the rotation of the bolt 6 and improving stability again.

[0031] When it is necessary to release the adsorption, it is only necessary to rotate the rotating shaft 17 to control the rotation of the cover 18 until the cover 18 rotates to no longer cover the air inlet 16. At this time, the gas in the outside will enter the hollow rod 14 from the air inlet 16, thereby releasing the adsorption of the suction cup 15. When the rotating shaft 17 is released, the rotating shaft 17 and the cover 18 will quickly rotate and reset under the elastic potential energy of the torsion spring 21, and the cover 18 will rotate again to cover the air inlet 16.

[0032] In the utility model, when installing the friction component, first control the locking rod 10 to move in the direction away from the friction plate 4 until the end of the locking rod 10 moves out of the through opening 8. At this time, the threaded openings 7 on the surface of the steel back 5 are aligned with the multiple threaded grooves respectively, and then multiple bolts 6 are respectively inserted from the multiple through openings 8 and threadedly installed in the threaded openings 7 and the threaded grooves until the larger end of the bolt 6 abuts against the through opening 8. The installation of the friction component can be completed, and the side wall of the larger end of the bolt 6 will correspond to the position of the locking rod 10. At this time, release the locking rod 10, and the end of the locking rod 10 will quickly move and reset under the elastic potential energy of the telescopic component, and be inserted into the locking groove 11 corresponding to its own position, thereby locking the bolt 6 and limiting the rotation of the bolt 6, thereby improving stability and eliminating the safety hazard of loosening of the connection due to the rotation of the bolt 6.

[0033] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
