Detailed description of the invention
Below in conjunction with the accompanying drawings a kind of preferred implementation of the present utility model is described in detail.
As illustrated in fig. 1 and 2, described forklift gear-box gearshift includes top cover 10, shifting shaft 20, gear level 40, gear shifting pulling head 50, gear arm 60, neutral safety switch 70 and the switch 80 that reverses gear.
Being threaded hole on described top cover 10, be provided with through hole, described neutral safety switch 70 and the switch 80 that reverses gear and be threaded on top cover in top cover, described shifting shaft 20 is movably installed in the through hole of top cover, and through gear shifting pulling head 50 and gear arm 60.
Described gear shifting pulling head 50 taper bolt is fixed on shifting shaft 20, this gear shifting pulling head with translating about shifting shaft or can rotate, described gear arm 60 is axially fixed in the through hole of top cover by stop screw 61, it can rotate around described shifting shaft 20 in the circumferential, and this gear arm offers the arc guide groove for coordinating its rotary motion in its circumferential direction.
One end of described shifting shaft 20 is arranged with return spring 30, this return spring is sealingly mounted at the end of described top cover 10 by spring cover cap 31, the other end of shifting shaft 20 is hinged with one end of gear level 40, the other end of gear level 40 is hinged with described gear arm 60, gear level can swing around gear arm, drive shifting shaft moves left and right, it is achieved thereby that the rotation of shifting shaft and moving left and right, the gear shifting pulling head 50 being fixed on shifting shaft achieves the selection of change speed gear box gear along with the motion of shifting shaft.
As shown in Figure 3, gear shifting pulling head 50 is fixed on shifting shaft 20, keep consistent with the motion of shifting shaft, so far the selection of first three rear two each gear is achieved, offering the notch 51 for simulating change speed gear box gear and flange 52 on the face of cylinder of described gear shifting pulling head 50, described flange 52 is to be perpendicular to the keyway that gear shifting pulling head is axial, and described notch 51 is distributed in described flange both sides, the direction of this notch is axially in parallel with described gear shifting pulling head, and the height of its flange is more than the height of described notch.
