The conventional shock absorber is provided with damping oil between the outer cylinder and the piston rod, so that the connected inner cylinder and the piston rod cannot be separately disassembled. When the inner cylinder and the piston rod are to be replaced, the shock absorber must be disassembled from the locomotive's triangular pedestal and the axle to be replaced. When the axle is disassembled, the wheel is disassembled, such as a brake caliper, The components such as soil removal must be re-installed and corrected, and since the piston rod connected to the outer tub is screwed, when the screw is to be removed, the piston rod will rotate with the same rotation, and the screw cannot be removed. It will not be the same when it is fixed. At this time, it is necessary to fix the piston rod with an additional fixing tool (commonly known as the Poseidon fork in the industry), so that the screw can be removed from the piston rod, so that the piston rod can be disengaged from the outer cylinder, which will cause the disassembly. The change of work is very complicated, and there are shortcomings that need to be improved.

Therefore, it is necessary to provide a novel and progressive shock absorber to solve the above problems.

The main object of the present invention is to provide a front wheel damper for a locomotive, which can replace the inner cylinder and the piston rod of the front wheel damper of the locomotive without disassembling the axle, thereby improving the working speed of the replacement, and having a simple structure, easy installation and large Reduce assembly time.
