The invention provides a net touching force balance mechanism for a pantograph, the pantograph and an electric truck. The net touching force balance mechanism comprises a bottom box, the top of the bottom box is connected with a large arm assembly through a pull rod assembly, and the top of the large arm assembly is connected with a pantograph head assembly through a small arm assembly; the device is characterized in that a support is hinged to the top of the bottom box, a balance wheel is hinged into the support, and one end of the pull rod assembly is wound around the outer edge of the balance wheel through a steel wire rope; in the ascending or descending process of the pantograph head assemblies on the two sides, the support drives the balance wheel to synchronously swing around the first rotating shaft, when a wire net has a height difference or a vehicle inclines, the pressure borne by the single-side pantograph head assembly is increased, the single-side pull rod assembly is pulled upwards, the balance wheel rotates around the second rotating shaft, and the pull rod on the other side drives the pantograph head assembly on the corresponding side to ascend. Thus, the net touching force of the pantograph head assemblies on the two sides is balanced, and the problem that the net touching force of the two pantograph heads of an existing truck pantograph is unbalanced is solved.
本发明提供一种用于受电弓的触网力平衡机构、受电弓及电动卡车,包括底箱,底箱的顶部通过拉杆组件连接大臂组件,大臂组件的顶部通过小臂组件连接弓头组件;其特征在于:底箱顶部铰接有支架,在支架的内部铰接有摆轮,拉杆组件的一端通过钢丝绳缠绕于摆轮的外缘;在两侧弓头组件的上升或下降过程中,支架带动摆轮可以绕第一转轴同步摆动,当线网有高度差或车辆出现倾斜使得单侧弓头组件受线网压力变大,单侧拉杆组件被上拉,摆轮将绕第二转轴转动,通过另一侧拉杆带动对应侧弓头组件上升,也即增大另一侧弓头组件的触网力,从而实现两侧弓头组件的触网力平衡以解决现有卡车受电弓两弓头的触网力不平衡问题。
