Abstract
A motorcycle chain automatic tensioning device comprises a support arm, the support arm comprises an upper support arm and a lower support arm, the upper support arm and the lower support arm are connected through a rotating shaft, a torsional spring uses the rotating shaft as a mandrel, one end of the torsional spring is fixed on the upper support arm, the other end of the torsional spring is fixed on the lower support arm, a shaft hole is arranged at the other end of the upper support arm, and a guide wheel is disposed at the other end of the lower support arm. According to the motorcycle chain automatic tensioning device, the chain automatic tensioning device is installed on a motorcycle rear wheel shaft through the shaft hole arranged at one end of the upper support arm, a helical torsion spring is used for acting between the upper support arm and the lower support arm, by means of the torsional force of the spring, the guide wheel at one end of the lower support arm lifts a drooping chain of a motorcycle, and the chain is tensioned. The torsional force of the helical torsion spring exists all the time, so that the supporting force of the guide wheel acting on the drooping chain of the motorcycle exists all the time, the chain of the motorcycle is in a tensioning state all the time and can not be loosened, the chain is not required to be adjusted manually within an extremely long period, and great conveniences can be brought for numerous motorcycle users.
Description
Technical field
The utility model belongs to technical field of motorcycles, is specifically related to a kind of motorcycle chain automatic tensioner.
Background technology
At present, motor bike is very universal in the rural area, especially enjoys youthfully to like.Present motor bike all exists an obvious defects to be, the driving chain Chang Song of motor bike, the power of motor bike are that the big chain plate transmission was gone after sprocket wheel drove through driving chain before the driving engine; After about 1000 kilometers of motorcycle drivings; The messenger chain wearing and tearing are elongated, and if necessary tight chain is tight chain; Chain is bobbed and woven greatlyyer in the process of moving, falls chain easily.Falling the stuck meeting of chain when motor bike is run at high speed causes the accident.Artificial tight chain is then time-consuming takes a lot of work, and repairs loaded down with trivial detailsly, then needs the tight chain of professional and technical personnel, otherwise can draw motor cycle rear wheel partially, causes front and back wheel inconsistent, bad riding, and driving running deviation, chain chain drum noise is big, and chain wear is fast.
The utility model content
The purpose of the utility model is to solve the above-mentioned technical matters that exists in the prior art, and a kind of motorcycle chain automatic tensioner is provided.
For realizing the foregoing invention purpose, the technical scheme that the utility model adopts is following:
The motorcycle chain automatic tensioner of the utility model comprises trailing arm, and described trailing arm is made up of last trailing arm and following trailing arm; Connect through rotating shaft between last trailing arm and the following trailing arm; Torsion spring is mandrel with the rotating shaft, and an end is fixed on the trailing arm, and the other end is fixed on down on the trailing arm; The last trailing arm other end is provided with axis hole, is installed on the motorcycle rear axle, and the following trailing arm other end is provided with guide wheel.
The other end at following trailing arm is provided with wheel frame, and the guide wheel center is provided with an axis, and guide wheel is installed on the wheel frame through this axis and a fastening connection piece.
The described automatic chain tensioner of the utility model is that the axis hole through one end of trailing arm on it is installed on the motorcycle rear axle,
And act between trailing arm and the following trailing arm with a helical torsional spring, by the torsion of spring, the guide wheel of the following trailing arm one end chain that motor bike is sagging holds up, and makes chain tension.Because the torsion of helical torsional spring exists always; Then guide wheel acts on the also existence always of holder power on the sagging chain of motor bike; Motorcycle chain is in tension and can not becoming flexible all the time; So in one quite long period, do not need the manual adjustment chain, bring bigger convenience for vast motor bike user.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the running condition figure of the utility model.
The specific embodiment
The motorcycle chain automatic tensioner of the utility model is as shown in Figure 1; Comprise trailing arm; Described trailing arm is made up of with following trailing arm 5 last trailing arm 2, connects through rotating shaft 4 between last trailing arm 2 and the following trailing arm 5, and torsion spring 3 is a mandrel with rotating shaft 4; One end is fixed on the trailing arm 2, and the other end is fixed on down on the trailing arm 5; Last trailing arm 2 other ends are provided with axis hole 1, are provided with wheel frame 6 at the other end that descends trailing arm 5, and guide wheel 7 centers are provided with an axis, and guide wheel 7 is installed on the wheel frame 6 through this axis and a fastening connection piece.
The practical view of the utility model is as shown in Figure 2; Big chain plate 10 transmissions were gone after sprocket wheel 8 drove through driving chain 9 before the driving engine; About 1000 kilometers of motorcycle drivings, when driving chain wearing and tearing are elongated, the automatic tensioner of the utility model is installed on the motorcycle rear axle; The guide wheel of tensioner prevents chain holding in the palm tight chain automatically.
