Abstract

A snow proof mechanism for a spring system used in a high speed EMU; a low-temperature resistant snow proof shield (5) of an integral vulcanized structure is disposed conforming to an air spring capsule (6) and an upper air spring cover plate pinch plate (2); low-temperature resistant snow proof shields are fixedly connected to both the upper air spring cover plate pinch plate and the upper air spring cover plate via an external flying ring (4) and hose clamp (3). The snow proof shield occupies the space between the air spring and the upper cover, thus avoiding precipitation, ensuring the performance of the air spring, and satisfying operation requirements at -40°C.

Description

高速动车组用弹簧系统防雪机构Snow system for spring system for high-speed EMU
技术领域 Technical field
　　本实用新型涉及高速动车组用弹簧系统防雪结构。 The utility model relates to a snowproof structure of a spring system for a high-speed motor train.
背景技术 Background technique
随着中国高铁技术的发展，高速动车组技术已日趋成熟，但目前缺少能够适应高寒地区运行的具有防冰雪功能的高速动车组转向架用弹簧系统防雪装置，因此，实用新型一种能够满足高寒运行要求的高速动车组用弹簧系统防雪装置是十分必要的，该装置可有效填补空气弹簧上盖板与胶囊之间的空隙，避免了大量的冰雪进入该间隙，从而保证了车辆运行时空气弹簧发挥正常的运行功能。 With the development of China's high-speed rail technology, high-speed EMU technology has become increasingly mature, but there is currently no spring system snow protection device for high-speed EMU bogies that can adapt to the operation of high-cold areas. Therefore, the utility model can meet the high cold. It is very necessary to run the required spring system snow protection device for high-speed EMU. The device can effectively fill the gap between the upper cover of the air spring and the capsule, avoiding a large amount of ice and snow entering the gap, thus ensuring the air spring when the vehicle is running. Play a normal running function.
