TH524C3 - Motorcycle front shock absorber system - Google Patents

Abstract

The front shock absorber according to this invention is a closed system. It is structured as two round cylindrical tubes held together by a small tube below and a large tube at the top. One end of the small tube is inserted into the large tube with shock spring, shock piston, Flow control valve, oil compression valve There is oil as a binder within the system. By internal oil The system must always be higher than the oil compression valve. And has an air gap at the top It is divided into 3 chambers, the 1st is at the bottom, the second is on the top of the shock piston head, the third is on the top of the flow control valve. These 3 chambers are connected by oil and when the force comes Action, the shock spring will collapse The oil is compressed by the valve. Causing part of the oil to flow through the control valve It flows to chamber 2 and oil to chamber 1 flows to chamber 3. Front shock absorbers collapse down. When there is no force, the spring will hold the oil from the third chamber to the 1st chamber, and the oil in the second chamber flows, but flows slowly. The front shock absorber will stretch up, so the front shock absorber system will absorb vibration (force action).

1. The motorcycle front shock absorber system consists of a round cylinder head forks. The top head has a convex hexagon that can be screwed down by a tool, and the lower side is an external thread. In order to connect the shaft The side of the housing low down to the outer thread and a groove on the top, this groove must have an oil-proof O-ring. The outer thread of the shock head is for tightening the shock cylinder. And inside this shock head will There is a hole in the middle which has a thread inside as well. This thread is screwed onto the valve stem. The shock cylinder has a long hollow cylinder at the top end with an oil-resistant o-ring seat. It has an internal thread for tightening the shock head together. The lower end of the shock cylinder is larger. At the bottom there is an internal shoulder for Install the low oil seal down with a groove. For oil seal lock ring And internal shoulder for installing a dust seal This shock absorber serves as a primary control for the shocks to move up and down vertically. The shock absorber oil seal features oil resistance, heat resistance, wear resistance, hard wear. It is characterized by a thick cylinder ring, the internal structure is a hard material covered with synthetic material. Serves to prevent oil pressure from flowing out of the system. Lock ring, oil seal, shock core There is a circular ring. Has a spring feature, can be compressed and then returned to its original position. Serves to prevent oil seals, shock absorbers from moving. Shock-proof, oil-resistant, heat-resistant, wear-resistant, hard-wearing seals It is characterized by a thick cylindrical wing ring, the internal structure is a hard material coated with synthetic material. Acts to prevent dust or foreign matter from Outside into the system Oil press valve stem It looks like a round bar at both ends with an external thread. With the top thread screwed on With a threaded hole in the center of the shock head And the bottom thread will be screwed onto the piston forks. The oil compression valve is located between the oil seal bushing and the oil compression valve stem. It looks like a round coin, smaller than a hole. Inside the cylinder a little shock. And in the middle there is a hole For threading the end of the oil compression valve stem to the piston, shock and side The side of the center hole will drill at least one hole. To reduce the resistance of the oil The compression valve must always be submerged in oil. Oil resistant bush Looks like a bar, cylindrical, round. Has an angle of inclination at the surface not all the way to the lower end, drilling a large hole and Not penetrated and at the upper head pierces a small hole through the lower end Oil resistant bush It serves to prevent oil chamber 1 from flowing out and to stop the movement of the shock rod from moving further. Shock piston has a hollow round cylinder shape. The upper end of the piston rod There is an internal thread for securing the threaded end of the oil-compression valve stem. At this end, the oil-resistant bushing is worn. Next down the sides, drill at least one hole to allow oil to flow out of chamber 1. At the bottom end is the head of the piston rod, which is always larger than the piston rod. But smaller in size The interior of the shock core The side of the piston head has a groove. For wearing piston rings The top part of the piston is spring together. Bumps on And put from the bottom of the shock rod, the shock piston acts as an intermediary fixing the top set. (Shock Cylinder Kit, Fork Head Set, Oil Compression Valve Stem Set) and Bottom Kit (Shock core set, shock absorber lower set) not to fall apart. The shock spring is a short, circular material contained in the fork shaft and mounted on the head of the fork piston. It serves to prevent the piston head from hitting the direct flow control valve. The shock absorber core has a long cylindrical shape. Inside and through to each other At the bottom end is an inner thread for screwing to the shock axle and with an oil resistant o-ring seat at the bottom. The upper end is slightly smaller to prevent compression between the fork surface and the inner wall of the cylinder. And at the top end of the pipe, the inside has a partition wall, creating a room 2 and a third, both of which pass through each other. In this partition, there is a flow control valve that allows the oil to flow quickly but slowly flows.When the shock absorber collapses, the 3rd chamber oil is quickly compressed into the second chamber and while the shock absorber extends. The second chamber oil will flow out slowly, resulting in a viscosity within the shock absorber spring system looks like a round, long coil material. Which is contained in the shock core Acts as a force exerted by the outside And serves to stretch back to its original position Nut cover the end of the shock rod. It has a circular cylinder. The lower head is made of convex angles to allow the screwdriver to rise to an external thread. For screwing to the end of the shock absorber shaft. Down to make a groove Add O-rings to prevent oil from flowing out of the system. And in the middle of the bottom end there is an inner thread In order to fasten the shock sleeve to the shock shaft, the lower shock sleeve has a round cylinder, the upper head is drilled in a deep hole. But not penetrated, which can fit the shock core, the lower end is drilled in two sizes The first size is bigger than the bolt head, shock cover. But not penetrating to the top The second size pierces a smaller hole but goes through the top creating a shoulder. Which can make the shock lock, shock sleeve attached to the nut, cover the end of the shock core And the end of this shockproof sleeve is perforated Side to fix the wheel stud The lower shock cover also serves to hold the shock absorber shaft as one piece.
