Abstract

The motorcycle suspension system has a lower end cap on the shock absorber shaft, which is securely fitted inside the shaft. The center of the lower cap has an oil passage for the flow of shock absorber oil to and from the reservoir. The shock absorber shaft is mounted to the wheel mount, which in turn attaches to the lower fork of the motorcycle. At the bottom of the lower cap is a connecting tube, either fixed to the cap or another type of connection, which serves as a channel for the oil to flow into and out of the oil passage to the reservoir. The reservoir is a hollow cylinder with an oil passage on one side of the bottom, connected to the connecting tube. This passage leads to the base of the reservoir, where a cylinder is mounted on the inner surface. This cylinder divides the reservoir into a lower chamber for oil storage and an upper chamber for gas storage. The top of the reservoir is covered with a cap that has a gas filler port located in the center.

Claims (2)

1. The shock absorber assembly of a motorcycle consists of an outer cylinder (1) in which the inner diameter of the outer cylinder (1) acts as the piston rod (11), with the lower end of the piston rod (11) fitted into the push plate (13), which has a hollow body for the piston rod (11) to pass through. A piston (12) is installed at the lower end of the piston rod (11) in a position below the push plate (13), with the outer end of the piston (12) having an oil valve (16) fitted into the body of the piston (12), in the center of which are several oil holes (17) to reduce the resistance to oil flow. A shock absorber shaft (18) is inserted into the outer cylinder (1), with the inner upper end of the shock absorber shaft (18) fitted into the push plate (13), and the contact surface between the shock absorber shaft (18) and the outer cylinder (1) in a position above the seal (8) is a wear plate (19), with the inside of the shock absorber shaft (18) will be a spring rod (20) which will have a diameter and length that corresponds to the size of the shock absorber shaft (18). The bottom cap (21) will be fitted on the inside of the lower end of the shock absorber shaft (18) by a fastening method. The center of the bottom cap (21) will have an oil hole (22) which will be a channel for the oil to flow in and out to a number of oil reservoirs (23). Specifically, the oil reservoir (23) will be a hollow cylindrical or square cylinder. On one side of the bottom of the oil reservoir (23) will be an oil passage hole (26) which will be connected from the connection method (25). The oil passage hole (26) will continue to the bottom base (28). Inside the oil reservoir (23) will be a cylinder (30) installed on the inner surface of the oil reservoir (23). The cylinder (30) will divide the inside of the oil reservoir (23) into a lower chamber (31) for storing oil and an upper chamber (32) for storing gas. The top of the oil storage tank (23) is covered with a lid (34) which has a gas filling port (35) located in the center of the lid (34). 2. The suspension device of the motorcycle, according to claim 1, which at the bottom of the bottom cover (21) is a connection route (25) which is a cylindrical tube fixed to the bottom of the bottom cover (21) or is a connection of any kind which is a channel for the flow of oil into and out of the oil hole (22) of the bottom cover (21) to the oil reservoir (23).
