一种常接触式防止钢弹簧断裂的方法及垂向止挡
摘要：
一种常接触式防止钢弹簧断裂的方法及垂向止挡，在橡胶主体上方设回转体状的橡胶凸台，在机车空载时橡胶凸台就与构架导筒接触；调节橡胶凸台和橡胶主体的直径或高度能调节垂向止挡的刚度；调节橡胶主体上的环形平直段与水平面之间的夹角，能调节垂向止挡的变刚度；橡胶凸台与橡胶主体通过环形圆弧段连接，调节垂向止挡的环形圆弧段的段数能调节垂向止挡变刚度的次数；底座嵌在垂向止挡的橡胶主体中，使底座能对垂向止挡进行限位，调节底座的高度能调节垂向止挡限位的位置和垂向止挡的刚度；通过调节垂向止挡的刚度、变刚度和限位的位置来减小钢弹簧承受的垂向载荷，降低机车运行过程中钢弹簧产生的金属疲劳，从而防止钢弹簧断裂。
摘要（英）：

A vertical backstop for preventing steel spring break, wherein the vertical backstop (1) is located in the steel spring (2), characterized in that the vertical backstop (1) comprises a rubber main body (11), a rubber convex platform (12) and a pedestal (13), wherein a revolve solid shaped rubber convex platform (12) is provided above the rubber main body (11), the rubber main body (11) is provided with an annular straight section and an annular arc section (115), the rubber convex platform (12) is connected with the rubber main body (11) via the annular arc section (115), a pedestal (13) is provided underneath the rubber main body (11), and the bottom of the rubber main body (11) is provided with a cavity (114), wherein the rubber main body (11), the rubber convex platform (12) and the pedestal (13) are an entirety.
