specific Embodiment approach 1
[0021] Embodiment 1: In this embodiment, a method for manufacturing an aluminum-ceramic composite brake disc is carried out according to the following steps:
[0022] 1. Prefabrication of ceramic skeleton disc core: According to the actual needs of the friction surfaces of the left and right brake discs, the ceramic skeleton with pores is manufactured as the blanks of the left disc 3, the right disc 4 and the connecting column 5, and the left disc 3, The right disk 4 and the connecting column 5 are combined to form a disk core, and the disk core assembly is obtained after cooling;
[0023] 2. Aluminum alloy smelting and casting disc body: use a smelting furnace to smelt aluminum alloy to obtain molten aluminum; put the disc core group obtained in step 1 into a extrusion casting mold, inject molten aluminum into the extrusion casting mold, The pressure is applied and maintained by the pressurizing equipment to complete the impregnation of the molten aluminum into the disk core ...
specific Embodiment approach 2
[0026] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the aluminum-ceramic composite brake disc is composed of a disc core 1 and a disc body 2; the disc core 1 is composed of a left disc 3, a right disc 4 and Composed of connecting columns 5; the left plate 3, the right plate 4 and the connecting column 5 are all ceramics, the centers of the left plate 3 and the right plate 4 are provided with symmetrical through holes, and the left plate 3 and the right plate 4 are placed in the left and right center, The inner sides of the left disc 3 and the right disc 4 are evenly distributed with several cylindrical pits 6; the left disc 3 and the right disc 4 are connected through evenly arranged connecting posts 5 through fusion heat sealing; the disc body 2 It is made by extrusion casting of aluminum alloy, and the left side of the disc body 2 is provided with a boss protruding from the left disc 3, and several threaded holes 7 are machined on the surface ...
specific Embodiment approach 3
[0027] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that: the porous ceramics described in step one are foamed ceramics or foamed ceramics; the porosity of the porous ceramics is 5% to 50% %. Others are the same as those in Embodiment 1 or 2.
