    • 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 10A 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.
    • 本发明提供一种能够根据碰撞时的冲击水平而使减震器的功能开启和关闭的减震结构,从而降低了更换减震器的频率。 在构成减震装置10A的负载操作单元11的后表面上安装有负载传递轴12和减震器13。 负载传递轴12穿过减震器的中心并且经由经由径向延伸的销15连接到支撑单元14。 减震器13的后端与支撑单元14之间具有间隙。 销15具有形成在其上的切口槽21。 当施加小负载时,负载从负载操作单元11通过负载传递轴12,销15和支撑单元14传递到主体,使得负载不被施加在减震器13上。 当施加大负载时,销15从形成有切口槽21的位置断开,封闭板17的表面与支撑单元14碰撞,从而使负载传递到减震器13,冲击是 有效吸收。

    • A car structure is provided which has the required strength against vertical load and vibration while avoiding increase in weight of the structure. At an entrance 6 of the railroad car structure 20 in which a side structure 2 is formed by a hollow member, the side structure 2 and a frame 7 are coupled via an L-shaped fitting 10. The L-shaped fitting 10 consists of a first joint part 10a which is in the form of a plate and couples a vehicle outer face plate 8 and a vehicle inner face plate 9 and a second joint part 10b which is in the form of a plate and butt welds a part of the first joint part 10a near the vehicle outer face plate 8 and the frame 7. Plate thickness of the second joint plate 10b is larger than plate thickness of the vehicle outer face plate 8. As a result, the required strength against vertical load can be ensured without increasing the plate thickness of the vehicle outer face plate 8, in other words, with little increase in weight of the structure.
    • 提供了一种汽车结构,其具有对垂直载荷和振动的所需强度,同时避免了结构的重量增加。 在侧面结构2由中空构件形成的铁路车辆结构体20的入口6处,侧面结构2和框架7经由L形配件10联接。 L形配件10包括第一接合部分10a,其为板的形式,并且将车辆外表面板8和车辆内表面板9和第二接头部分10b的形式 在车辆外表面板8和框架7附近的板和对接焊接第一接合部分10a的一部分。 第二接合板10b的板厚比车辆外面板8的板厚大。 结果,可以在不增加车辆外面板8的板厚度的情况下,即,结构的重量增加很小的情况下,能够确保所需的抗垂直载荷的强度。

    • The invention provides a transportation device having a shock absorbing device with a reduced non-collapse region. Shock absorbers 14 and 17 constituting a shock absorbing device 10A provided on a transportation device is connected respectively to shock absorbers 17 and 20 disposed rearward therefrom via connecting members 23 and 26 having ashtray-like cross-sectional shapes. The shock absorber 20 disposed at the rearmost position is connected via welding to a base 29. Collapse regions 15, 18 and 21 of the shock absorbers 14, 17 and 20 are collapsed by the load applied to the shock absorbers 14, 17 and 20, and their lengths are shortened. Non-collapse regions 16 and 19 of the shock absorbers 14 and 17 overlap respectively with the non-collapse regions 19 and 22 of the shock absorbers 17 and 20 disposed rearward therefrom. Therefore, the non-collapse regions 16, 19 and 22 fit within a recessed portion of the connecting members 23 and 26, and the overall longitudinal length of the non-collapse regions of the shock absorbing device can be shortened.
    • 本发明提供了具有减小的非崩溃区域的减震装置的运输装置。 构成设置在运送装置上的减震装置10A的减震器14和17分别通过具有烟灰缸状横截面形状的连接构件23和26分别连接到其后方设置的减震器17和20。 设置在最后位置的减震器20通过焊接连接到基座29。 减震器14,17和20的折叠区域15,18和21被施加到减震器14,17和20的负载折叠,并且它们的长度被缩短。 减震器14和17的非塌陷区域16和19分别与设置在其后方的减震器17和20的非塌陷区域19和22重叠。 因此,非塌陷区域16,19和22装配在连接构件23和26的凹陷部分内,并且可以缩短减震装置的非塌陷区域的整个纵向长度。
