The invention relates to the technical field of trailer chassis, in particular to a length-adjustable trailer chassis. Comprising a chassis frame body, the chassis frame body is slidably connected with a chassis front frame, the chassis front frame is fixedly connected with fixing cylinders distributed in a mirror image mode, first piston shafts are slidably connected into the fixing cylinders distributed in the mirror image mode, and the inner side of the chassis frame body is fixedly connected with oil passing pipes distributed in a mirror image mode; a flexible pipe is fixedly connected and communicated between the fixed cylinder and the adjacent oil pipe, the oil pipe is fixedly connected and communicated with a butt joint pipe, the butt joint pipe is in sliding connection with a second piston shaft, a sliding shaft is fixedly connected in the chassis frame body, and the sliding shaft is in sliding connection with a heavy block fixedly connected with the second piston shaft. The gravity center position of the chassis frame body is changed through sliding of the heavy block, so that the gravity of the chassis frame body counteracts centrifugal force borne by the touring car during turning, and rollover of the touring car due to the centrifugal force during turning caused by non-uniform distribution of objects in the touring car is avoided.

    本发明涉及拖挂车底盘技术领域,尤其涉及一种长度可调式拖挂房车底盘。包括有底盘架体,所述底盘架体滑动连接有底盘前架,所述底盘前架固接有镜像分布的固定筒,镜像分布的所述固定筒内均滑动连接有第一活塞轴,所述底盘架体的内侧固接有镜像分布的通油管,所述固定筒与相邻的所述通油管之间固接且连通有柔性管,所述通油管固定连接且连通有对接管,所述对接管滑动连接有第二活塞轴,所述底盘架体的内部固接有滑轴,所述滑轴滑动连接有与所述第二活塞轴固接的重块。本发明通过重块滑动改变底盘架体的重心位置,使底盘架体的重力抵消房车拐弯时受到的离心力,避免房车内部物体的分布不均匀,导致车辆拐弯时受离心力出现侧翻。
