Description
本申请涉及轨道车辆技术，具体地，涉及一种拉杆座、车体及轨道车辆。The present application relates to rail vehicle technology, in particular, to a drawbar seat, a car body, and a rail vehicle.
近年来，随着我国高铁技术的迅猛发展，已经得到全世界范围的认可。出口美国、加拿大等国家的铁路客车订单逐年增加。美国、加拿大等国一般会要求铁路客车采用他们自己的转向架，由于美国、加拿大等国的转向架结构与我国国内的转向架结构不同，且转向架与车体的接口部分布置在车体两侧，与我国相关车体的转向架接口结构不同，因此，在向美国、加拿大等国家出口轨道客车时，需要设置与他们的转向架相匹配的拉杆座。In recent years, with the rapid development of China's high-speed rail technology, it has been recognized worldwide. Railway passenger car orders to the United States, Canada and other countries have increased year by year. The United States, Canada and other countries generally require railway passenger cars to use their own bogies. The structure of the bogies of the United States and Canada is different from that of China's domestic bogies, and the interface between the bogie and the car body is arranged on the car body. The side is different from the bogie interface structure of the relevant car body in China. Therefore, when exporting rail cars to the United States, Canada and other countries, it is necessary to set a tie rod seat that matches their bogie.
相关美国、加拿大的车体装配的拉杆座采用板材组焊而成，拉杆座焊接在车体的底架边梁，并且整体结构满足抗压缩及抗冲击要求。由于相关拉杆座与车体底架边梁组焊在一起，成为车体组成中的一部分，在线路上运行的列车发生严重碰撞事故后，拉杆座会与转向架的连杆产生刚性碰撞，碰撞能量过大时则会使拉杆座产生变形甚至断裂，导致车体边梁产生扭曲变形，进而影响整车安全性，导致后期维修难度大的问题。The tie rod seats assembled in the car bodies of the relevant United States and Canada are formed by plate welding. The tie rod seats are welded to the underframe side beams of the car body, and the overall structure meets the requirements of compression and impact resistance. As the related tie rod seats are welded together with the side frame beams of the car body and become part of the car body composition, after a serious collision accident occurs on the train running on the line, the tie rod seats will have a rigid collision with the connecting rod of the bogie If it is too large, the tie rod seat will be deformed or even broken, resulting in torsional deformation of the side beams of the car body, which will affect the safety of the entire vehicle and lead to the problem of difficulty in later maintenance.

由于上述拉杆座3为分体结构，并由可拆卸连接的连接座32和基座31构成，使拉杆座3具有一定的结构强度，能够满足正常使用；但是，由于连接座32和基座31之间为可拆卸连接，基座31与连接座32之间的连接强度会小于基座31或连接座32本身的结构强度，连接座32与基座31之间的连接处形成拉杆座3的薄弱点，因此，在转向架2发生碰撞过程中，由于转向架2与拉杆座3之间固定连接，转向架2会通过拉杆21和构架体22将碰撞能量传递给拉杆座3，当碰撞能量较大时，连接座32与基座31之间的连接处会在碰撞能量的作用下发生破坏，使连接座32从基座31上脱离，以防止转向架2的碰撞能量通过拉杆座3传递到车体1而使车体1发生变形或损坏，从而实现对车体1的保护，进而保证车体内的人员或物品的安全，将碰撞损失最小化，能够提高轨道车辆整车的安全性；同时，由于连接座32与基座31为可拆卸连接结构，在连接座32变形或损坏后便于进行维修或更换，采用上述拉杆座3还能够降低后期的维修难度。Since the drawbar base 3 is a split structure and is composed of a detachably connected connecting base 32 and a base 31, the drawbar base 3 has a certain structural strength and can meet normal use; however, since the connecting base 32 and the base 31 The connection between the base 31 and the connection base 32 will be less than the structural strength of the base 31 or the connection base 32 itself. The connection between the connection base 32 and the base 31 forms the rod base 3 Weak point, therefore, during the collision of the bogie 2, due to the fixed connection between the bogie 2 and the tie rod seat 3, the bogie 2 will transfer the collision energy to the tie rod seat 3 through the tie rod 21 and the frame body 22, when the collision energy When it is larger, the connection between the connection base 32 and the base 31 will be destroyed by the impact energy, so that the connection base 32 is detached from the base 31 to prevent the collision energy of the bogie 2 from being transmitted through the tie rod base 3 Go to the car body 1 and deform or damage the car body 1 to realize the protection of the car body 1, thereby ensuring the safety of people or objects in the car body, minimizing the collision loss, and improving the safety of the rail vehicle; At the same time, because the connecting base 32 and the base 31 are detachable connecting structures, it is easy to repair or replace after the connecting base 32 is deformed or damaged.
