The front fork is a guiding mechanism of the motorcycle, and the frame is organically connected with the front wheel. The front fork is composed of a front shock absorber, an upper and lower connecting plate, a direction column and the like. The direction column is welded with the lower joint plate, and the direction column is set in the front casing of the frame. In order to make the direction column motorcycle move flexible, an axial thrust ball bearing is arranged at the upper and lower shaft neck positions, and the left and right sides are connected through the upper and lower plates. The front shock absorbers are joined together into a front fork.
Front and rear shock absorbers: The front shock absorber is used to attenuate the vibration caused by the impact load of the front wheel and keep the motorcycle running smoothly.
The rear shock absorber and the rear rocker arm of the frame constitute the rear suspension of the motorcycle. The rear suspension device is an elastic connecting device between the frame and the rear wheel, which bears the load of the motorcycle, reduces and absorbs the shock and vibration transmitted to the rear turn due to the uneven road surface.
Wheels: The front wheels of motorcycles are guide wheels, and the rear wheels are drive wheels, all of which are spoke wheels. The wheels are composed of tires (inner and outer tires), rims, spokes, hubs, brake brake rims, bearings, and front and rear axles. The rim (steel ring) is rolled and welded from a steel plate. The hub is die-cast from aluminum alloy, and the brake rim is inlaid and integrally molded with flanges at both ends for mounting spokes. The spokes are similar in shape to bicycle strips for connecting the rim and the hub. The hub is equipped with a brake, the front wheel is also equipped with a worm gear and a worm of a speedometer, and the rear wheel is equipped with a drive mechanism.
