Embodiment Construction

[0021] Combine below Attached picture The patent of the present invention is further described.

[0022] A high heat capacity SiCp / A356 composite wheel-mounted brake disc, Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 shown.

[0023] The total height of the disc body is 51.5 mm, the outer diameter of the friction ring 1 is Ф640 mm, and the inner diameter is Ф350 mm. The thickness of the inner and outer diameters of the disc body friction ring 1 is smaller at 27 mm, and the thickness at the middle diameter is larger at 33 mm. Such as figure 2 shown.

[0024] The high ribs 2 are radially arranged, 3 high ribs 2 form a group, a total of 6 groups are evenly distributed along the circumferential direction, and the angle between two adjacent high ribs 2 is 6°, Such as figure 2 shown. The top thickness of the high rib 2 is 8mm, the root length of the high rib 2 is 125mm, and the end face and side slope of the high rib 2 are 5...

Abstract

The invention relates to high-heat-capacity SiCp/Al composite material wheel-mounted brake disc bodies. The high-heat-capacity SiCp/Al composite material wheel-mounted brake disc bodies are made of SiCp/Al composite materials. Each high-heat-capacity SiCp/Al composite material wheel-mounted brake disc body comprises a friction ring (1), high plate bars (2), connection columns (3), short plate bars (4), positioning columns (5), bolt holes (6) and positioning grooves (7), wherein the section of the friction ring (1) is trapezoid; every three high plate bars (2) fall into one set, and totally six sets of high plate bars (2) are evenly distributed in the circumferential direction; each combined bar A is composed of one high plate bar (2) and one connection column (3), and twelve combined bars A are evenly distributed in the circumferential direction; each combined bar B is composed of two high plate bars (2), one short plate bar (4) and one positioning column (5), and six combined bars B are evenly distributed in the circumferential direction; the bolt holes (6) are formed in the connection columns (3); and the positioning grooves (7) are formed in the positioning columns (5). The two disc bodies are located on the two sides of a wheel, axial positioning between the disc bodies and the wheel is achieved through bolts, and circumferential positioning between the disc bodies and the wheel is achieved through positioning pins. The disc bodies deform concertedly, the internal temperature is even, and stress is small.

Description

technical field [0001] The invention relates to the field of urban rail transit, in particular to a high heat capacity SiCp / Al composite material wheel-mounted brake disc body. The disc body is cast and is suitable for urban rail trains and fast freight cars with a speed below 140km / h. Background technique [0002] Brake discs, as the basic brake components of rail transit trains, play a vital role in ensuring the safe operation of trains. As "energy saving and environmental protection" has attracted more and more attention from countries all over the world, lightweight technology has also been widely used in various industries related to the national economy and people's livelihood. The lightweight of rail trains is of great significance in reducing energy consumption, saving traction kinetic energy, and reducing train operating costs. In particular, reducing the weight of components such as brake discs and brake pads can significantly reduce the unsprung weight of the bog...
