Technical Field

[0001] The utility model relates to the technical field of automobile joysticks, in particular to a novel hydraulic cylinder. Background Art

[0002] The shift lever is a tool that changes the moving parts from one speed to another in a vehicle. It can change the meshing of the gears in the transmission, change the vehicle's driving speed, and the driving force changes accordingly. The existing shift lever is usually equipped with a hydraulic cylinder, which is mainly used to lock the shift lever and unlock the shift lever after the vehicle is started, thereby realizing the control function of the vehicle.

[0003] The existing patent (publication number: CN207486030U) discloses that "the utility model relates to the field of vehicle gear shifting technology, and in particular to a gear shift cylinder. The utility model discloses a gear shift cylinder, including a cylinder body, a piston, a piston shaft, a gear shift device and an anti-shifting device. The piston shaft and the fork shaft are made into one piece, which effectively enhances the connection strength between the gear shift cylinder and the fork. The gear shift device facilitates the gear shifting operation of the gear shift cylinder through the double oil ports; moreover, the anti-shifting device can effectively prevent the axial rotation of the piston shaft, reduce the failure of the gear shift device, and avoid the occurrence of gear shifting. At the same time, the manual lever arranged outside the piston shaft is convenient for the operator to manually adjust the gear shift cylinder to the neutral state during maintenance and inspection."

[0004] In the process of realizing the utility model, the inventor discovered that the prior art had the following problems: two rubber rings are arranged inside the existing hydraulic cylinder, one of which is fixed, and the other moves with the movement of the internal movable rod. The rubber ring will produce friction with the inner wall of the cylinder over a long period of use, causing damage, which can easily lead to oil leakage in the cylinder and shorten the overall service life of the cylinder.

[0005] Therefore, the utility model provides a novel hydraulic cylinder to solve the problems raised in the above background technology. Utility Model Content
