Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle parts, and particularly relates to a chain tension adjuster for a light motorcycle. Background Technique

[0002] A motorcycle is an internal combustion locomotive. Power is generated by the engine and transmitted to the chain through gears to achieve the motion state. During the long-term movement of the chain, friction and wear will occur, and the tension and slack of the drive chain will also change. Therefore, a chain tension adjuster is installed at the position of the chain to adjust the tightness of the chain. The chain tension adjuster is a type of tension regulator applied in the drive chain system. It works together with the drive chain and automatically adjusts the tightness of the chain to ensure the normal operation of the entire drive system.

[0003] According to a motorcycle chain adjuster proposed in the publication number: CN218929708U, a first fixing part and a second fixing part are provided at the top of the first connecting rod. The first fixing part and the second fixing part are connected by a pin. One end of the bottom of the first connecting rod and one end of the second connecting rod are connected by a bolt. The other end of the second connecting rod is connected with a sprocket. Through holes are provided on the sides of the first connecting rod and the second connecting rod close to each other. Both ends of the spring are fixed in the through holes and connected to the first connecting rod and the second connecting rod. By setting a chain adjuster at the motorcycle chain, the chain can be tightened by adjusting the angle of the adjuster to stretch the elongated gear. When the motorcycle chain is stretched and loosened, it can be temporarily adjusted to ensure driving safety. The motorcycle chain adjuster can control the angle of the sprocket according to different degrees of looseness and is applicable to different motorcycles. It is convenient to operate and install and is user-friendly.

[0004] According to the above introduction, the adjuster used for the motorcycle chain adjusts the tension of the chain by the elastic force of the spring. However, after long-term use of the spring, its own elastic force will change, resulting in a decrease in the elastic force stretching of the spring. Therefore, the effect of adjusting the tension of the motorcycle chain is reduced. To solve the above-mentioned problems, an improved chain tension adjuster for a light motorcycle is proposed.

The other end of the adjusting rod 7 is movably connected to the back of the connecting rod 4. By setting the adjusting mechanism 3, the moving seat 2 can be driven to move up and down on the connecting seat 1. Thus, with the cooperation of the positioning component 6, the moving seat 2 can drive the position of the adjusting wheel 5 on the connecting rod 4 through the adjusting rod 7. Therefore, the tension of the chain can be adjusted. The structure is simple, which is convenient for the staff to adjust and prolongs the working time of the chain tension adjuster.

[0023] The adjusting mechanism 3 includes a threaded sleeve 31. The threaded sleeve 31 is embedded in the top of the connecting seat 1. A lead screw 32 is movably connected to the top of the moving seat 2. The upper end of the lead screw 32 passes through the connecting seat 1 and extends upward through the cooperation of the threaded sleeve 31.
