Explanation.
As shown in Figure 1 to Figure 3, steeraxle, including pontic 1, a pair of the knuckles 5, two-way cylinder for being located at 1 end of pontic
2 and connecting rod 4, wherein, the piston rod 3 of two-way cylinder 2 is connected with corresponding knuckle by connecting rod, same by two-way cylinder
Step drives knuckle 5.
Two-way cylinder 2 includes 201, piston 202 of cylinder body and is connected in a pair of pistons bar 3 of piston both sides, wherein, cylinder body
201 are fixed on 1 middle position of pontic, i.e. two-way cylinder by bearing is located at the middle position of two knuckles, and both sides are received
Dynamic balance.
Piston 202 is located inside cylinder body 201, by oil pressure can drive piston cylinder interior move, piston 202 it is cylindrical
It is provided with cannelure week, in cannelure, is provided with sealing cup 207.
The inner of piston rod 3 is connected with pistons end by screw thread.Specifically, pistons end is provided with screwed hole, piston rod
The external screw thread of the inner be adapted with the screwed hole of piston, connection is reliable, and assembling is simple.
201 two ends of cylinder body are equipped with sealing ring 204, and piston rod 3 passes through sealing ring 204, and piston is located at cylinder interior, passes through
Cylinder body is divided into two cavitys by piston 202.201 end of cylinder body is provided with internal thread, sealing ring by with cylinder ends internal thread phase
The nut 203 of adaptation is positioned.
On the outside of sealing ring 204 and 201 inwall of cylinder body between, sealing is equipped with the inside of sealing ring and piston rod outer surface between
Circle.The end excircle of sealing ring is provided with annular groove, and annular groove is engaged with the nut portion stretched in cylinder body.Will be close by nut
