The invention relates to a chassis connecting device suitable for a middle axle trailer, and relates to the technical field of middle axle trailers, the middle axle trailer comprises a main vehicle and a trailer body, the trailer body is connected with a chassis of the main vehicle through a traction device, and the connecting device comprises a cross beam assembly used for being transversely arranged between vehicle frames on the two sides of the chassis of the main vehicle, the two sides of the cross beam assembly are used for being connected with two frames correspondingly; two supporting arm beams which are arranged on the two sides of the cross beam assembly respectively, one end of each supporting arm beam is used for being connected with a traction device, and the other end of eachsupporting arm beam is used for being connected with a frame; the width of the supporting arm beam is gradually increased from the end, connected with the traction device, of the supporting arm beam to the end, connected with the frame, of the supporting arm beam. The width of the end, connected with the trailer frame, of the supporting arm beam is increased, the connecting area of the supportingarm beam and the trailer frame is increased, the connecting rigidity of the supporting arm beam and the trailer frame is improved, more impact loads of the trailer can be transmitted to the trailer frame through the supporting arm beam, and the effect of better dispersing the impact loads of the trailer is achieved.

    本申请涉及一种适用于中置轴挂车的底盘连接装置,涉及中置轴挂车技术领域,该中置轴挂车包括主车和挂车,挂车通过牵引装置与主车的底盘连接,该连接装置包括横梁组件,其用于横设于主车的底盘两侧的车架之间,且横梁组件的两侧分别用于与两个车架连接;两个托臂梁,两个托臂梁分设于横梁组件的两侧,托臂梁的一端用于与牵引装置连接,另一端用于与车架连接;且托臂梁的宽度由托臂梁与牵引装置连接的一端朝托臂梁与车架连接的一端逐渐增大。托臂梁与车架连接的一端的宽度增大,增大了托臂梁与车架的连接面积,增大了托臂梁与车架的连接刚度,且使得托臂梁能将挂车的冲击荷载更多地传递至车架,起到更好的分散挂车的冲击荷载的作用。
