下面结合附图对本公开实施方式提供的电力机车转向架的各部件进行详细说明:The components of the electric locomotive bogie provided by the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings:
如图4和图5所示,构架200可包括焊接而成的侧梁、横梁和端梁,且侧梁、横梁及端梁可形成第一安装口201、第二安装口202和第三安装口203,其中:第一安装口201 和第二安装口202可位于构架200的两端,且都能够放置转向架驱动系统100,用来为本申请的电力机车转向架提供动力;第三安装口203可位于构架200的中部,能够放置牵引装置300,该牵引装置300用于连接构架200与电力机车。As shown in Figures 4 and 5, the frame 200 can include welded side beams, cross beams and end beams, and the side beams, cross beams and end beams can form a first installation opening 201, a second installation opening 202 and a third installation Port 203, where: the first installation port 201 and the second installation port 202 can be located at both ends of the frame 200, and both can be used to place the bogie drive system 100 to provide power for the electric locomotive bogie of this application; the third installation The port 203 can be located in the middle of the frame 200 and can place a traction device 300 for connecting the frame 200 and the electric locomotive.

Specifically, the hanger 11 can be hung on the suspension parts 211 of the first installation port 201 and the second installation port 202. on. As mentioned above, the number of hangers 11 on the permanent magnet traction motor in the bogie drive system 100 is three, and they are distributed in a triangle, so the number of the suspension parts 211 of the first installation port 201 and the second installation port 202 is equal There are three, and they are all triangular.
因为第一安装口第一安装口201和第二安装口202相对第三安装口203凸出,所以靠近第三安装口203的悬挂点A相对远离第三安装口203的悬挂点B及悬挂点C位置较低,则与悬挂点A配合的吊挂件11可以为吊臂111,而与悬挂点B及悬挂点C配合的吊挂件11可以为吊杆112,如图7所示,该吊杆112的高度大于吊臂111的高度。Because the first installation opening, the first installation opening 201 and the second installation opening 202 protrude relative to the third installation opening 203, the suspension point A near the third installation opening 203 is relatively far away from the suspension point B and the suspension point of the third installation opening 203 If the position C is low, the hanger 11 that matches the suspension point A can be a boom 111, and the hanger 11 that matches the suspension point B and the suspension point C can be a boom 112, as shown in FIG. The height of 112 is greater than the height of boom 111.

该弹性芯轴113具有一定的刚度和弹性,俗称“软关节”,可对转向架驱动系统100和构架200之间的相对运动进行缓冲。举例而言,该弹性芯轴113可以为棱柱结构,从而避免弹性芯轴113与吊臂111及吊杆112端头的开孔产生相对转动,进而使得吊挂件11与构架200的稳固连接。更进一步,如图8所示,弹性芯轴113的外部还可套有橡胶圈114,以更好地对转向架驱动系统100和构架200之间的相对运动进行缓冲。The elastic mandrel 113 has certain rigidity and elasticity, and is commonly called a "soft joint", which can buffer the relative movement between the bogie drive system 100 and the frame 200. For example, the elastic mandrel 113 may be a prismatic structure, so as to prevent the elastic mandrel 113 from rotating relative to the openings at the ends of the boom 111 and the boom 112, thereby making the hanger 11 and the frame 200 firmly connected. Furthermore, as shown in FIG. 8, a rubber ring 114 may be sleeved on the outside of the elastic mandrel 113 to better buffer the relative movement between the bogie drive system 100 and the frame 200.
