Chain adjuster assembly and motorcycle thereof

Abstract

The invention discloses a chain adjuster assembly. The chain adjuster assembly comprises a bottom fork and a chain adjusting component mounted in a bottom fork side pipe. The chain adjusting component comprises an adjuster main body which is provided with a wheel axle via hole and is in sliding fit with the bottom fork side pipe, a position adjusting mechanism used for driving the adjuster main body to slide longitudinally along the bottom fork side pipe, and an adjuster suspension plate used for indicating the position of a wheel axle. The adjuster suspension plate is provided with a limiting lug, and the two transverse side faces of the limiting lug are used for being matched with the adjuster main body so that the limiting lug can limit rotation of the adjuster main body around the wheel axle via hole. Accordingly, the error of the bending angle of the limiting lug does not affect the limiting precision of the limiting lug, the universality of the assembly is good, and the assembly can be used for sectional material bottom forks and can also be used for special-shaped bottom forks. In addition, the suspension plate in the structural form can be exchanged left and right, and the mold cost is reduced.

Description

technical field [0001] The invention relates to a chain adjuster component, in particular to a chain adjuster assembly and a motorcycle thereof. Background technique [0002] The motorcycle chain adjuster is installed on the left and right ends of the rear axle as a whole, and is located in the left and right pipes of the flat fork. The side pipe of the flat fork is provided with a strip hole for the rear axle to pass through. The stud on the body passes through the baffle at the rear end of the flat fork side tube and is locked by the nut. When the nut is turned, the stud drives the main body of the chain adjuster assembly to move back and forth in the flat fork side pipe, thereby driving the rear axle. It moves synchronously along the strip hole on the side tube of the flat fork to adjust the tension of the chain. In order to visually display the relative position of the axle and the strip hole, it is convenient for both ends of the axle to move along the strip hole of the...

[0002] The motorcycle chain adjuster assembly body is installed on the left and right ends of the rear wheel shaft, and is located in the left and right tubes of the flat fork. The side tubes of the flat fork are provided with strip holes for the rear wheel shaft to pass through. The chain adjuster assembly The stud on the body passes through the baffle at the rear end of the flat fork side tube and is locked by a nut. When the nut is turned, the stud drives the main body of the chain adjuster assembly to move back and forth in the flat fork side tube, and then drives the rear axle Move synchronously along the bar-shaped hole on the side tube of the flat fork to realize the adjustment of the chain tension. In order to visually display the relative position of the wheel shaft and the bar-shaped hole, it is convenient to move the two ends of the wheel shaft along the bar-shaped hole of the chain adjuster assembly To keep the amount consistent, the existing motorcycle fork is provided with scale lines on both sides of the bar hole. In order to facilitate the user to accurately read the movement amount of the wheel shaft, the chain adjuster assembly is usually also provided with a hanging plate, and the wheel shaft passes through this The hanging plate can also drive the hanging plate to move. The side line of the hanging plate can be used as a reference line when reading the movement amount. When bending the plate, the hanging plate is limited by the contact between the bending surface and the flat fork. The bending angle error will affect the accuracy of the limit, which will cause the hanging plate to rotate when the nut is tightened, and the limit is unreliable; in addition, The existing hanging boards can only be used for profile flat forks (such as rectangular tube flat forks), and the left and right hanging boards cannot be interchanged, and their versatility is poor
