Locomotive shock absorbers (Part 1)

Abstract

A locomotive shock absorber (a) includes: a connecting seat, a pressure cylinder, a gas cylinder, and a mass damper; wherein the connecting seat has: a pressure cylinder connecting recess connected to the pressure cylinder, and a gas cylinder connecting recess connected to one end of the gas cylinder; a channel is provided inside the connecting seat between the pressure cylinder connecting recess and the gas cylinder connecting recess for mutual communication; the mass damper is assembled at the other end of the gas cylinder; according to this structure, when assembled on a locomotive, during riding, the damping oil is pushed into the gas cylinder through the channel by the compression action of the damping rod in the pressure cylinder, so that the damping oil is pushed into the gas cylinder by the compression action of the damping rod in the pressure cylinder, thereby reducing the damping oil pressure. In addition to providing gas to balance the cylinder pressure and achieve a shock absorption effect, the mass damper can also be used to provide high-frequency vibrations when the motorcycle is traveling on rough roads or cornering at high speed. The weight block in the mass damper can swing in the opposite direction to dissipate the vibration energy transmitted to the motorcycle body, reduce small vibrations, thereby improving tire grip, stability, riding comfort, reducing wear on shock absorber components, and extending the service life of the vehicle. Furthermore, even on bumpy roads, it can still provide stable control and enjoy a smooth riding experience.

The piston is fitted onto the upper section of the damping rod body and can move axially along the inner tube. Its outer periphery contacts the inner periphery of the inner tube to form a tight fit. A through hole is provided in the center of the piston, which communicates with the interior of the hollow tube-shaped damping rod body. The elastic element is fitted into the top of the inner tube and its bottom end contacts the top surface of the piston. The top cover has an external thread section at its lower section, which is locked together with the internal thread section at the top of the inner tube.

4. The locomotive shock absorber as described in claim 1, wherein, One end of the pressure cylinder is connected to the pressure cylinder connecting recess of the connecting seat. It includes: a main cylinder, a piston, and a compression spring. The internal chamber of the main cylinder is filled with damping oil and is stopped by the piston. A piston rod protruding outside the main cylinder is fixed at the bottom of the piston. A connecting end is fixed at the bottom of the piston rod. The compression spring is coaxially sleeved on the periphery of the main cylinder. The two axial ends of the compression spring are respectively restricted by the free end of the piston rod and the screw block of the main cylinder, so as to push the piston rod back to the uncompressed position after the load is removed.
