Embodiment Construction

[0022] In order to describe the technical solutions of the present invention in detail, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Apparently, the described embodiments are some, not all, embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 2-4 , the multi-stage flywheel of the variable-speed bicycle of the present invention includes several gears 1 for speed-changing, and spacers 2 for spacing are arranged between the gears 1. Of course, the multi-stage flywheel of the variable-speed bicycle belongs to the prior art, and is no longer described here repeat.

Abstract

The invention relates to the technical field of a variable speed bicycle, in particular to a multi-level flying wheel of the variable speed bicycle. The multi-level flying wheel comprises a plurality of gears, wherein gaskets are arranged between the gears and are made from a material capable of absorbing lubricating oil. Due to the fact that the gaskets can absorb the lubricating oil, the lubricating oil for lubrication between the gears and the chain of the variable speed bicycle are not easy to flow, i.e., the lubricating oil does not directly flow from the gaskets but after being absorbed by the gaskets, the lubricating oil is dispersed to the places between the gears and the chain of the variable speed bicycle by centrifugal force during rotation of the gaskets, the effect of lubrication is achieved, the lubricating oil is fully used, the lubricating oil is prevented from being wasted, the lubricating oil is not required to be frequently added to the multi-level flying wheel of the variable speed bicycle, and maintenance and use of the variable speed bicycle are facilitated. Furthermore, springs are arranged on the peripheries of the gaskets, so that the springs can protect the gaskets and prevent impurities, such as dust from entering the gaskets, and the lubricating oil must be dispersed from the clearances of the springs, so that the absorbing effect is better.

Description

technical field [0001] The invention relates to the technical field of variable-speed bicycles, in particular to a multi-stage flywheel of a variable-speed bicycle. Background technique [0002] Generally speaking, a variable speed bicycle will be equipped with a multi-stage flywheel. The multi-stage flywheel includes several gears with different outer diameters. When the bicycle is moving, the chain can be placed on different gears through the gear shifting, thereby changing the speed of the vehicle to adapt to different gears. road conditions and the physical strength of the cyclist. [0003] Such as figure 1 As shown, it is an existing multi-stage flywheel of a speed-changing bicycle, which includes several gears 101, and the several gears 101 are arranged sequentially from the inside to the outside, from large to small. Although each gear 101 has a different outer diameter and a different number of teeth, it has the same inner diameter as the installation hole for fixe...
