The piston oil slinger can be changed according to the size of a required piston, the outer edge of the piston oil slinger with smaller size is overlapped with the outer edge of the mounting platform, and the piston with larger size increases the width of the mounting platform, so that the edge of the mounting platform is positioned outside the outer edge of the oil slinger.
Preferably, the outer edge of the slinger is inboard of the outer edge of the mounting platform.
Preferably, the oil guide hole has a circular shape.
Preferably, the oil guide groove is circumferentially and uniformly arranged on the oil deflector ring.
Preferably, the number of the oil guide holes is two or more, and the number of the oil guide grooves is two or more. The quantity of leading the oilhole and leading the oil groove can be adjusted according to concrete need, can change the draining speed when the piston up both sides motion after the quantity of adjusting leading the oilhole and leading the oil groove, reaches the flow resistance of both sides when adjusting the piston compression.
And the utility model discloses a damper piston only needs the upside to establish the elastic valve piece, and the piston reciprocates, and the fluid of damper intracavity just flows the transfer from the upper and lower both sides of piston repeatedly. The material of an elastic valve plate is saved through the structural design, the structure of the elastic plates arranged on two sides is changed into the structure of the elastic plate arranged on one side, the disassembly and the assembly are more convenient during replacement, the damage probability is reduced, and the service lives of the piston and the shock absorber are further prolonged.
The utility model discloses owing to adopted above technical scheme, have apparent technological effect: the utility model relates to a saved the material of an elastic valve piece, the structure of both sides installation elastic sheet changes to the structure that is equipped with the elastic sheet to one side, dismantles the installation during change and all more convenient, has also reduced the probability of damage. The shock absorbers in different sizes are adapted by adjusting the size of the piston and the number of the oil guide holes and the oil guide grooves, and the liquid resistance of two sides of the piston during working is adjusted.
