The invention provides a variable-gradient load mechanism. The variable-gradient load mechanism comprises an earring joint; a rear housing; and a core rod which is arranged between the earring joint and the rear shell, one end of the core rod and the earring joint are relatively limited, and the other end of the core rod can move relative to the rear shell; bushings with first springs are arranged on the two sides, close to the earring connector and the rear shell, of the core rod respectively, check rings are arranged at ports of the bushings, a second spring is arranged between the two bushings, the elastic force of the second spring is larger than that of the first spring, and the bushings are limited by limiting mechanisms arranged on the corresponding sides of the core rod; wherein the core rod and the rear shell are partially sleeved with the main shell, a cavity of the lining is formed between the main shell and the core rod, and the main shell and the rear shell are relatively fixed. The variable-gradient load mechanism has a large force gradient during small displacement and a small rod force gradient during large displacement control, the operation precision during small displacement is improved, and the control burden of a driver during large displacement is reduced.
本申请提供了一种变梯度载荷机构,所述变梯度载荷机构包括:耳环接头;后壳体;以及设置在耳环接头和后壳体之间的芯杆,所述芯杆一端与耳环接头相对限位,另一端能够与后壳体相对移动;在芯杆上靠近耳环接头和后壳体的两侧分别设置具有第一弹簧的衬套,衬套的端口具有挡圈,两衬套之间设有第二弹簧,所述第二弹簧的弹力大于第一弹簧的弹力,且所述衬套被芯杆上相应一侧设置的限位机构限位;部分的套在设置芯杆和后壳体上的主壳体,所述主壳体与芯杆之间形成有衬套的空腔,且主壳体与后壳体相对固定。本申请的变梯度载荷机构在小位移时有较大的力梯度,大位移操纵时有较小的杆力梯度,提高了小位移时的操作精度、降低了大位移时的驾驶员操纵负担。
