如图1是本发明的结构示意图，图2是本发明的滚子滑动机构的结构示意图，一种适应小半径曲线的转向架及机车，包括转向架架体1、驱动电机6、车轮轮体7、叉头8、牵引杆体9和端头10，车轮轮体7固定连接在车轴上，车轴转动连接在转向架架体1上，驱动电机6的机体固定在转向架架体1上，驱动电机6的输出轴端固定在车轴端头处，牵引杆体9一端固定有叉头8，牵引杆体9另一端固定有端头10，叉头8固定连接在转向架架体1上，所述转向架架体1上固定有装配框2，装配框2的开口处滑配连接有顶板3，顶板3固定在橡胶堆4一端，橡胶堆4另一端固定在车体上，装配框2与顶板3之间安装有滚子滑动机构5。所述滚子滑动机构5由圆柱滚子51、座槽52和滑板53组成，座槽52内放置有数根相互平行的圆柱滚子51，滑板53下端面贴合在圆柱滚子51上，滑板53上端面固定在顶板3上。所述装配框2、顶板3、滚子滑动机构5组成滚子橡胶堆装配机构，转向架架体1上安装有四组滚子橡胶堆装配机构。所述转向架架体1上的四组滚子橡胶堆装配机构位于同一个圆周上。所述车轮轮体7过盈配合在车轴上。所述叉头8通过螺栓和螺母与转向架架体1固定连接在一起。所述叉头8和端头10分别焊接连接在牵引杆体9两端。所述机车的转向架为权利要求1-7中任意一项所述的转向架。Figure 1 is a schematic structural diagram of the present invention, and Figure 2 is a schematic structural diagram of the roller sliding mechanism of the present invention, a bogie and locomotive adapted to a small radius curve, including a bogie frame body 1, a drive motor 6, and wheel bodies 7. The fork head 8, the traction rod body 9 and the end 10, the wheel body 7 is fixedly connected to the axle, the axle is rotatably connected to the bogie frame body 1, and the body of the driving motor 6 is fixed on the bogie frame body 1 to drive The output shaft end of the motor 6 is fixed at the end of the axle. One end of the traction rod body 9 is fixed with a fork 8; the other end of the traction rod body 9 is fixed with an end 10; the fork 8 is fixedly connected to the bogie frame 1. An assembly frame 2 is fixed on the frame body 1, and a top plate 3 is slidably connected to the opening of the assembly frame 2. The top plate 3 is fixed at one end of the rubber pile 4, and the other end of the rubber pile 4 is fixed on the car body. A roller sliding mechanism 5 is installed between. The roller sliding mechanism 5 is composed of a cylindrical roller 51, a seat groove 52, and a sliding plate 53. A number of cylindrical rollers 51 parallel to each other are placed in the seat groove 52. The lower end of the sliding plate 53 is attached to the cylindrical roller 51. The upper end surface of 53 is fixed on the top plate 3. The assembly frame 2, the top plate 3, and the roller sliding mechanism 5 constitute a roller rubber stack assembly mechanism. Four sets of roller rubber stack assembly mechanisms are installed on the bogie frame 1. The four roller rubber stack assembly mechanisms on the bogie frame body 1 are located on the same circumference. The wheel body 7 is interference fit on the axle. The fork head 8 is fixedly connected to the bogie frame 1 by bolts and nuts. The fork head 8 and the end head 10 are respectively welded and connected to the two ends of the traction rod body 9. The bogie of the locomotive is the bogie described in any one of claims 1-7.
结合附图1和附图2所示，滑板53可以在一排水平放置的圆柱滚子51上滑动。当滑板53左右直线移动时，圆柱滚子51通过摩擦力进行自转滚动。而滑板53固定在顶板3上，因此顶板3与滑板53是同步移动的。当车体与转向架架体1发生相对位移的时候，装配框2与顶板3的相对滑动，可以帮橡胶堆4分担一大部分的水平位移，橡胶堆4只需产生少量的水平位移和扭转。使得橡胶堆4不用经常大角度的变形，大大提高了橡胶堆4的使用寿命。As shown in FIG. 1 and FIG. 2, the sliding plate 53 can slide on a row of horizontal cylindrical rollers 51. When the sliding plate 53 linearly moves left and right, the cylindrical roller 51 rotates and rolls by friction. The sliding plate 53 is fixed on the top plate 3, so the top plate 3 and the sliding plate 53 move synchronously. When the car body and the bogie frame body 1 are relatively displaced, the relative sliding of the assembly frame 2 and the top plate 3 can help the rubber pile 4 share a large part of the horizontal displacement, and the rubber pile 4 only needs to produce a small amount of horizontal displacement and torsion. . Therefore, the rubber pile 4 does not need to be deformed frequently at a large angle, and the service life of the rubber pile 4 is greatly improved.
转向架架体1上的四组滚子橡胶堆装配机构分布在同一个圆周上，橡胶堆4可以在圆周切线方向上自由滑动。使橡胶堆4在较小变形的基础上通过小半径的曲线，可大大改善橡胶堆4的使用工况，有利于提高橡胶堆4的使用寿命。The four sets of roller rubber stack assembly mechanisms on the bogie frame 1 are distributed on the same circumference, and the rubber stack 4 can slide freely in the tangential direction of the circumference. Making the rubber pile 4 pass through a curve with a small radius on the basis of a small deformation can greatly improve the working conditions of the rubber pile 4 and help increase the service life of the rubber pile 4.
