Problems solved by technology

The current transmission structure of automatic vehicles is that the hub is connected to the flywheel, and the flywheel is driven by a chain to realize the driving effect of the flywheel on the hub. Drive the chain to drive the flywheel on the rear side of the body to drive the wheels. The 360° rotation of the pedals requires the user's knees to move a lot, and the transmission efficiency is relatively low. Long-term riding will damage the user's knees to a certain extent and consume a lot of physical strength. The chain needs to be readjusted after a period of use, and it is inevitable that the chain will be dropped

Abstract

The invention discloses a traction device, which relates to the technical field of traction devices, and includes a bracket, an outer drive structure, and an inner transmission structure. The inner transmission structure includes a hub, a brake disc, and a flywheel. The bracket is rotatably connected to the hub, and the One side of the hub is provided with the brake disc, the other side is provided with the flywheel, both ends of the hub are provided with concave holes, the concave holes are provided with bearings, the hub is rotatably connected with a drive shaft, and the hub is rotatably connected to the drive shaft. The drive shaft penetrates through the hub and the bearing, the outer drive structure includes a drive outer plate and a drive outer disc, and both ends of the drive shaft are provided with the drive outer plate and the drive outer disc. The advantages of the present invention are that the transmission efficiency is extremely high compared to the traditional pedaling mode, the range of motion of the user's legs is reduced, the wear of the knees is reduced, the user can ride for a longer time, and the physical strength is saved; The axle runs through the hub to improve transmission efficiency.

Description

technical field [0001] The invention relates to the technical field of traction devices, in particular to a traction device. Background technique [0002] Bicycles, also known as bicycles or bicycles, are usually two-wheeled small land vehicles. Bicycles have become a favorite transportation and fitness tool for residents of all countries in the world, especially developed countries. It is a relatively common sports, fitness, leisure and entertainment products. After a person rides on a car, it is a green and environmentally friendly means of transportation that uses the pedals as power. The current automatic vehicle transmission structure is that the hub is connected to the flywheel, and the flywheel is driven by the chain to realize the driving effect of the flywheel on the hub. The structure is relatively complex, the maintenance is difficult, and the transmission efficiency is relatively low. Drive the chain to drive the flywheel on the rear side of the body to drive th...
