The invention discloses a primary suspension device of a suspension type freight sky train. The device is arranged between a framework and an integrated transmission case. The integrated transmissioncase is formed by integrating a transmission case and an axle box and is in transmission connection with a wheel set; four spiral steel springs are symmetrically arranged at an upper part of the integrated transmission case and positioned on two sides of the wheel set; and the four spiral steel springs are connected with the framework, two axle box pull rods which are symmetrical in a radial direction of the wheel set are arranged on the side, located on the wheel set, of the middle of the integrated transmission case, the two axle box pull rods are connected with the framework, and the spiralsteel springs and the axle box pull rods are arranged in the inner side of the wheel set. The suspension device aims at the suspension type freight sky train so that the freight sky train can inheritadvantages of a small occupied space, flexible marshalling, low energy consumption and low manufacturing cost of a passenger transport sky train, and meanwhile, freight efficiency can be improved.

    本发明公开一种悬挂式货运空铁的一系悬挂装置,设置在构架和集成传动箱之间,所述集成传动箱为传动箱和轴箱集成为一体,且与轮对传动连接;所述集成传动箱上部位于轮对两侧对称布置有四个螺旋钢弹簧,四个所述螺旋钢弹簧与所述构架连接,所述集成传动箱中部位于轮对一侧设置有沿轮对径向对称的两个轴箱拉杆,两个所述轴箱拉杆与所述构架连接,所述螺旋钢弹簧和轴箱拉杆内置于轮对内侧。该悬挂装置针对悬挂式货运空铁,使货运空铁能够继承客运空铁占地空间小、编组灵活、能源消耗低、制造成本低的优点,同时能提高货运效率。
