Balance lever structure for adjusting torque of throttle lever

The invention discloses a balance lever structure for adjusting the torque of a throttle lever, which comprises a cam shaft with two ends rotatably connected with a regulator shell, and the cam shaft is connected with the throttle lever through an internal spline and an external spline; the control lever is arranged on the upper side of the cam shaft and attached to the lift profile of the cam shaft. The balance lever is arranged on the lower side of the cam shaft and attached to the balance molded surface of the cam shaft, and the balance lever and the control lever are arranged in parallel. The torque of the throttle lever can be effectively adjusted, abrasion of parts is reduced, the service life of mechanical parts is prolonged, and reliability of the mechanical parts is improved. 本发明公开了一种调整油门杆扭矩的平衡杠杆结构，该结构包括：两端与调节器壳体转动连接的凸轮轴，凸轮轴和油门杆通过内外花键连接；控制杠杆，所述控制杠杆设置于凸轮轴的上侧、并与凸轮轴的升程型面相贴合；平衡杠杆，所述平衡杠杆设置于凸轮轴的下侧，并与凸轮轴的平衡型面相贴合，平衡杠杆和控制杠杆平行设置。本发明能够有效调整油门杆的扭矩，减轻零件的磨损，提高机械零件的寿命和可靠性。
