Abstract

The invention provides a shock absorbing structure capable of turning the function of the shock absorber on and off according to the level of shock during collision, thereby reducing the frequency of replacing shock absorbers. On a rear surface of a load operating unit 11 constituting a shock absorbing device 10 A are attached a load transmitting shaft 12 and a shock absorber 13. The load transmitting shaft 12 is passed through the center of the shock absorber and is connected to a supporting unit 14 via a pin 15 that extends toward the radial direction. The rear end of the shock absorber 13 faces the supporting unit 14 with a clearance therebetween. The pin 15 has notched grooves 21 formed thereto. When small load is applied, the load is transmitted from the load operating unit 11 through the load transmitting shaft 12 , the pin 15 and the supporting unit 14 to the main body, so that the load is not applied on the shock absorber 13 . When large load is applied, the pin 15 breaks from where the notched grooves 21 are formed, by which the surface of the closing plate 17 collides against the supporting unit 14 , so that the load is transmitted to the shock absorber 13 and the shock is absorbed effectively.

Description

technical field [0001] The present invention relates to a conveyor for predicting collisions of rail vehicles such as railway vehicles and monorail vehicles, and motor vehicles due to collisions. In particular, the present invention relates to a conveyor provided with a collision absorbing device composed of a collision absorbing material made of a material excellent in collision absorption characteristics for absorbing a collision during a collision. Background technique [0002] In recent years, in railroad vehicles, in order to ensure the safety of crew members and passengers at the time of collision, it is desired to provide a crushing area that absorbs the collision at the time of collision. In this regard, the following structure is proposed. A collision absorbing device is provided at the lengthwise end of the vehicle body of the front vehicle (including the last vehicle, the same below) and the middle vehicle, and the absorbing material installed at the extreme end o...

Problems solved by technology

Therefore, in the case of a structure in which the collision absorbing material is easily collapsed by effectively absorbing a collision, a load acts on the collision absorbing material every time a small collision occurs, and the collision absorbing material needs to be replaced every time, which may cause hinder operation and increase cost

In addition, in order to avoid this situation, when the impact absorbing material is made into a strong structure, the impact absorbing characteristics deteriorate, and when a large impact occurs, the impact absorbing material may not function effectively.
