Abstract

The invention relates to a bicycle front fork. The bicycle front fork comprises a vertical pipe, a fork shoulder, stroke pipes, outer pipes, fork feet and a fork bridge. The vertical pipe is connected with the fork shoulder. The stroke pipes comprise the left stroke pipe and the right stroke pipe and are installed at the two ends of the fork shoulder in a sleeving mode correspondingly. The lower ends of the stroke pipes are sleeved with the outer pipes. The fork feet are arranged under the outer pipes. The fork bridge is in bridge joint with the position between the outer pipes. A sealed oil storage chamber, a shock-proof spring, a gasket and a spring rod are sequentially arranged in each outer pipe from top to bottom. The periphery of each spring rod is provided with a negative-pressure spring. A piston is arranged between each sealed oil storage chamber and the corresponding shock-proof spring. Each sealed oil storage chamber is internally provided with an oil absorption sponge and is provided with an oil filling port. The bicycle front fork is good in stability, shockproof effect and damping effect and capable of meeting using requirements.

Description

technical field [0001] The invention relates to the technical field of bicycle components, in particular to a bicycle front fork. Background technique [0002] The front fork is the decisive soul part of bicycle comfort. The front fork part is in the front part of the bicycle structure. Its upper end is connected with the handlebar part, the frame part is matched with the front tube, and the lower end is matched with the front axle part to form the guide of the bicycle. system. The existing bicycle front fork also has the technical defects of poor stability, poor shock-absorbing effect and poor lubricating effect for a long time. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems in the prior art, and provide a bicycle front fork, which has good stability, good shock absorbing and damping effects, and can meet the needs of use. [0004] The technical solution adopted by the present invention to solve the techni...
