The invention discloses a primary rubber spring of a metro vehicle. The primary rubber spring is composed of an inner barrel, a rubber body and an outer sleeve, so that a framework can be installed on an axle box in a hanging mode, and the height of the framework and the height of a compartment floor are reduced. And meanwhile, the framework can adopt straight square steel tubes or I-shaped steel, so that the framework structure is simplified, and the cost is reduced. The rubber body is provided with an arc-shaped free surface, so that the primary rubber spring has vertical variable stiffness to meet the vibration reduction requirement of metro vehicles.
本发明公开了一种地铁车辆一系橡胶弹簧:采用由内筒、橡胶体及外套组成的一系橡胶弹簧,使得构架能够以吊挂的方式安装在轴箱上,以降低构架和车厢地板的高度。同时构架可以采用平直的方钢管或工字钢,简化了构架结构,降低成本。橡胶体具有弧形的自由面,从而使得一系橡胶弹簧具有垂向的变刚度,以满足地铁车辆的减振要求。
