The invention discloses a clutch control mechanism and a tractor. The clutch control mechanism comprises a pedal, a pedal control shaft, a rocker arm assembly and a first reset spring. One end of the pedal operating shaft is connected with the pedal, and the other end is connected with the rocker arm assembly; one end of the first reset spring is connected with the rocker arm assembly, and the other end extends in the direction away from the rocker arm assembly. The device further comprises a power assisting device. The power assisting device comprises a fixed part and a movable part; the fixed part and the movable part attract or repel each other; when the fixed part and the movable part attract each other, attraction pulling force is generated, and the attraction pulling force acts on the pedal when the pedal is treaded down and plays a role in assisting in the treading stroke. When the fixed part and the movable part repel each other, repulsive thrust is generated, and the repulsive thrust acts on the pedal when the pedal resets and plays a role in assisting in the resetting process. The power assisting device 5 plays a power assisting role in the treading and resetting processes of the pedal 1, the power assisting role is the largest at the treading tail section and the resetting initial section according to the treading and resetting characteristics of the clutch, the treading force of a driver on the pedal is greatly reduced, and the resetting response speed is increased.
本发明公开了离合器操纵机构及拖拉机,其中离合器操纵机构包括踏板、踏板操纵轴、摇臂总成以及第一复位弹簧;所述踏板操纵轴的一端与踏板连接,另一端与摇臂总成连接;所述第一复位弹簧一端与摇臂总成连接,另一端沿远离摇臂总成的方向延伸;还包括助力装置;所述助力装置包括固定件和活动件;所述固定件和活动件相互吸引或排斥;所述固定件和活动件相互吸引时产生吸引拉力,所述吸引拉力在踩下踏板时作用于踏板上,在踩踏行程中起助力作用;所述固定件和活动件相互排斥时产生排斥推力,所述排斥推力在踏板复位时作用于踏板上,在复位过程中起助力作用。本发明中的助力装置5在踏板1踩踏和复位过程中都起到助力作用,且依据离合器踩踏及复位特点,在踩踏末段和复位初期助力作用最大,大大降低驾驶员对踏板的踩踏力,提高复位响应速度。
