Abstract

The invention belongs to the technical field of unmanned vehicle suspension devices, and particularly relates to a lightweight upper cross arm of an unmanned vehicle and a manufacturing method thereof, the upper cross arm comprises a connecting plate, a lattice structure, a connecting rod and a connecting hole; the connecting plate is fixed to the upper portion of the suspension oil cylinder and used for transmitting wheel torque. The dot matrix interlayer is used for connecting the skin framework connecting rod structural bodies into a whole and meanwhile has the important function of transmitting loads. The connecting rod is used for transmitting the rotating torque of the axle load to the frame; the upper cross arm lattice model has the advantages of being high in specific strength, small in volume density and high in structural efficiency, through reasonable upper cross arm lattice model filling, the structural strength can be guaranteed, meanwhile, the structural lightweight level can be effectively improved, and the manufacturing cost and the structural weight can be controlled within a low range.

本发明属于无人车辆悬挂装置技术领域，具体涉及一种无人车轻量化上横臂及其制造方法，所述上横臂包含连接板、点阵结构、连杆、连接孔；所述连接板与悬架油缸上部固定，用于传递车轮扭矩；所述点阵夹层用于将蒙皮骨架连接杆结构体连接并形成整体，同时承担着传递载荷的重要功能；所述连杆用于传递轮轴载荷到车架的旋转力矩；所述连接孔用于与车架铰接固定，其具有比强度高、体积密度小、结构效率高的特点，通过合理的上横臂点阵模型填充，能够在保证结构强度的同时，有效提升结构轻量化水平，并能将制造成本和结构重量控制在较低范围内。
