自卸车
摘要：
一种自卸车，包括：车架、厢体、与厢体铰接的厢体后板和用以随自卸车厢体上升或下降动作而自动开启或关闭厢体后板的启闭锁紧机构，启闭锁紧机构包括铰接在厢体下端部的至少一套挂钩机构和安装在车架上的至少一套传动连接杆，传动连接杆的输出端与挂钩机构相铰接，挂钩机构包括：主动挂钩部分和至少一个从动挂钩部分，主动挂钩部分和从动挂钩部分沿自卸车厢体后板的宽度方向水平分布，传动连接杆驱动主动挂钩，主动挂钩部分通过传动轴带动从动挂钩部分联动，且挂钩部分的挂钩与固定在厢体后板下边缘的对应的钩接件钩接。通过多个点位的挂钩设置来确保厢体后板的下帮受力均匀，可有效防止下帮发生变形，以避免交通事故的发生，既简单，又可靠。
摘要（英）：

The utility model relates to a dump truck which comprises a frame, a compartment, a compartment backboard which is hinged with the compartment, an open-shut locking mechanism which can open or shut the compartment backboard automatically as the rising or descending of the dump truck compartment. The open-shut locking mechanism comprises at least a set of hook-hanging mechanism which is hinged with the lower end of the compartment and at least a set of driving connecting levels which are installed on the frame. The output ends of the driving connecting levels are hinged with the hook-hanging mechanism. The hook-hanging mechanism comprises a driving hook-hanging section and at least a driven hook-hanging section. The driving hook-hanging section and the driven hook-hanging section are distributed levelly along with width direction of the compartment backboard of the dump truck. The driving connecting levels drive driving hooks. The driven hook-hanging section is driven by a driving axle of the driving hook-hanging section, and the hook of the hook-hanging section is hooked with the hook fixed on the lower limp of the compartment back plate. The stress is even on the compartment backboard by hooking many points, and the lower part of the compartment can be prevented from deforming effectively. The utility model is simple, reliable, and by which traffic accidents can be avoided.
