Document Type and Number:
WIPO Patent Application WO/2015/122148
Kind Code:
A1
Abstract:
A railway vehicle wheel comprises: a wheel (10) provided with a plate section (13); and brake discs (1) provided with circular plate sections (2) which have front surfaces (2a) serving as slide surfaces and which also have fin sections (3) provided protruding from the back surfaces (2b) of the circular plate sections (2). The two brake discs (1) grip the plate section (13) of the wheel (10) with the slide surfaces of the brake discs (1) facing outward and are fastened within the regions of the slide surfaces. A smallest cross-section section, the cross-sectional area of which is the smallest in a cross-section of the space between the wheel (10) and a brake disc (1), the cross-section being taken circumferentially across the space, is present in a region formed by the outer peripheral surface (2c) of the circular plate section (2) and by the inner peripheral surface (12b) of a rim section (12). In a region starting at and outward of the smallest cross-section section, the outer peripheral surface (2c) of the circular plate section (2) extends along the inner peripheral surface (12b) of the rim section (12). The brake discs of the railway vehicle wheel have a simple shape and can be manufactured with high productivity, and an aerodynamic sound during high-speed traveling can be effectively reduced.
