Inside it is equipped with piston rod；Glais ring, Glais ring and piston are equipped between piston and inner wall of cylinder the inner cavity of cylinder barrel is divided into nothing
Rod cavity and rod chamber, are additionally provided with Y shape circle between one end of piston and piston rod；The other end of piston is equipped with check valve.
Further, one end of the piston rod is socketed with elastic spring.
Further, it is additionally provided with wear ring between the piston and cylinder barrel.
Further, the check valve includes the steel ball for being arranged on the piston other end, and spring, spring are connected with steel ball
Front is equipped with hollow screw plug.
Further, the other end of the piston is additionally provided with sealing ring and plug.
Further, the other end of the piston rod is also associated with earrings.
The beneficial effects of the utility model：A kind of oil cylinder follower, when oil cylinder is installed, piston rod is in piston seal
Space centre position, driver's cabin can fluctuate in truck runs over journey, and piston can be pulled when floating on driver's cabin
Bar is displaced outwardly, and the sealing space in piston will form parital vacuum at this time, when driver's cabin is fallen after rise under the effect of gravity
Wait, for piston rod with being moved together into cylinder barrel, the unnecessary air in piston interior sealing space goes out discharge from check valve, follows according to this
Ring, forms servo-actuated between cylinder piston rod and driver's cabin.The utility model is simple in structure, easy for installation, passes through piston rod, oil
Form servo-actuated between cylinder and driver's cabin, can effectively prevent the rigid connection of driver's cabin and oil cylinder, it is good to be servo-actuated effect, and tears open
Unload conveniently, easy to repair, accessory is common, and maintenance and production cost are not very high.
