为解决某车型行李舱门开启时弹力过大问题,探究改变行李舱门开启时弹力的方法,文章以鹅颈式铰链加扭杆弹簧的布置形式为研究对象,对行李舱门在各个开启状态时的受力情况加以分析。通过将行李舱门铰链摆臂安装孔位置上移(与原孔孔心距10 mm)和将扭杆弹簧固定端与活动端之间的初始角度由35°减小为30°,使行李舱门满足各个开启状态时的最佳受力情况,为今后的扭杆弹簧以及行李舱门铰链的设计提供了参考。
In order to solve the problem of excessive elastic force when a luggage compartment door of a vehicle is opened, the method of changing the elasticity of the luggage compartment door when opening is explored. Taking the arrangement form of the gooseneck hinge and torsion bar spring as the research object, When the force situation be analyzed. By moving the luggage compartment door hinge swing arm mounting hole upwards (10 mm from the original hole) and reducing the initial angle between the fixed end of the torsion bar spring and the movable end from 35 ° to 30 °, the luggage compartment Door to meet the best of all the open state of force, for the future torsion bar and luggage compartment door hinge design provides a reference.
