Abstract
Claims
1. A brake piston, comprising a connecting block (1), characterized in that: The upper surface of the connecting block (1) is connected to a stainless steel block (4), and the connecting block (1) and the stainless steel block (4) have the same diameter. A threaded mounting groove (5) is provided at the center of the upper surface of the stainless steel block (4). A limiting ring (6) is fixed to the upper surface of the stainless steel block (4) on the outside of the threaded mounting groove (5), and the center points of the limiting ring (6), the stainless steel block (4) and the connecting block (1) are located on the same vertical line. A zinc block (8) is provided above the threaded mounting groove (5), and a ceramic gasket is inlaid on the top surface of the zinc block (8). The bottom of the zinc block (8) is located inside the limiting ring (6), and a heat dissipation mechanism (9) is provided between the limiting ring (6) and the zinc block (8).
2. The brake piston of claim 1, wherein: The top of the connecting block (1) has two mounting slots arranged from bottom to top, and the first sealing ring (2) and the second sealing ring (3) are respectively connected inside the two mounting slots.
3. The brake piston of claim 1, wherein: A circular mounting protrusion is connected to the center of the lower surface of the zinc block (8). The outer surface of the circular mounting protrusion is provided with a thread that matches the thread groove on the inner wall of the threaded mounting groove (5). The diameter of the circular mounting protrusion is the same as the diameter of the threaded mounting groove (5).
4. The brake piston of claim 1, wherein: The heat dissipation mechanism (9) includes a copper ring (901) and heat dissipation fins (902). The copper ring (901) is located between the limiting ring (6) and the zinc block (8), and the inner and outer surfaces of the copper ring (901) are tightly fitted with the zinc block (8) and the limiting ring (6) respectively. Multiple heat dissipation fins (902) are connected at equal angles on the outer surface of the copper ring (901).
5. The brake piston of claim 4, wherein: The end of the heat dissipation fin (902) away from the copper ring (901) has a zigzag structure, and the multiple copper rings (901) are not in contact with the stainless steel block (4).
6. The brake piston of claim 5, wherein: Each of the copper rings (901) has a notch (7) on its outer side, and the notch (7) is opened at an equal angle on the upper surface of the limiting ring (6), and the width of the notch (7) is greater than the thickness of the copper ring (901).
7. The brake piston of claim 1, wherein: The connecting block (1) has a cavity (10) inside, and a reinforcing mechanism (11) is provided inside the cavity (10). The reinforcing mechanism (11) includes a mounting block (1101) and a connecting rod (1102). The mounting block (1101) is located in the middle of the cavity (10), and the upper and lower surfaces of the mounting block (1101) are fixedly connected to the inner wall of the cavity (10). Multiple connecting rods (1102) are evenly distributed on the outer surface of the mounting block (1101), and the end of the connecting rod (1102) away from the mounting block (1101) is in contact with the inner wall of the cavity (10).
