Description

Chainless transmission riding device

Technical Field

The invention relates to a riding device without chain transmission, in particular to a chainless transmission device.

Background

First, in the mechanical field, there are several connection modes between the driving end and the driven end (driven end), such as: a link, gear, chain, belt, etc., such that the drive end transmits power to the driven end (driven end) through a link, gear, chain, belt, etc.; in practice, various transmission modes have such drawbacks as: when the connecting rod is driven, the connecting rod often spans the rotating shaft of the driving end rotating part, which sometimes causes certain difficulty for the layout of parts of certain machines, the manufacturing steps of gears are complex, the materials and the manufacturing cost are relatively expensive, the chain and the belt are driven to have certain unreliability, and the chain and the belt are sometimes easy to break.

In the existing transmission modes through the connecting rod, the directions of the driving end and the driven end (driven end) cannot be reliably restrained when the driving end and the driven end move, so that the motion direction of the driven end (driven end) is clockwise sometimes, and the driven end is anticlockwise sometimes, and even the condition of motion dead points can occur.

Secondly, a planetary gear speed change device is known, wherein the planetary gear speed change device comprises an inner gear ring (sometimes also called a gear ring directly), a planet wheel and a sun wheel, and different speed change effects are formed by different movement modes of the inner gear ring, the planet wheel and the sun wheel; in the use of the general situation, one part of the annular gear, the planet wheel and the sun wheel is fixed and not rotated, and the other two parts are taken as input and one part is taken as output, for example, the annular gear is not rotated, the planet wheel carrier is taken as input, and the sun wheel is taken as output, so that a certain speed ratio is achieved, but if the rotation speed of the annular gear is adjusted while the planet wheel is taken as input and the sun wheel is taken as output, the gear ratio of the planet wheel and the sun wheel is directly influenced, so that the stepless speed change effect is achieved; reference is made to chinese patents CN107685828A and CN215370813U, which describe a continuously variable transmission in which a planetary gear set is used to achieve a continuously variable transmission effect, but which define the manner of using a motor as an input power source, a worm gear as a means of adjusting the speed of the ring gear, and a sun gear as an input and a planetary gear as an output; in general, the inner gear ring, the planet carrier and the sun gear can be used as an input end and an output end or a speed control end, in fact, the power source is not only a motor, but also various speed regulation modes are included, and the application range of the stepless speed change is greatly limited due to the limitation of the speed regulation modes.

Third, most bicycles on the market today employ gear shifting mechanisms to connect the rear wheel with the crankset, and the shifting function is achieved by shifting the manner in which the chain is coupled to the different shifting gear crankset. The speed change system has high requirements on the strength and the service life of the gear tooth disc, has a complex structure and high production cost, and can possibly generate the situation of discontinuous speed change during speed change.

Fourth, as a common transportation machine, the transmission modes of the electric bicycle with the motor in the middle of the bicycle, the motorcycle are as follows: gear drive, chain drive, shaft drive, belt drive, etc. Compared with other transmission modes, the chain transmission is the most widely applied, the structure is simple and light, the maintenance is easy, the transmission is stable, but the condition of chain falling is often encountered, the transmission shaft and a plurality of sets of bevel gears are used for power transmission by the shaft-driven bicycle, the condition of chain falling is avoided, the bevel gear processing requirement of the transmission shaft is high in precision and high in cost, the profit of the bicycle is lower, and a general bicycle enterprise cannot produce the transmission shaft and the bevel gears with reliable quality; the belt transmission is sensitive to temperature change, weak in environmental factor resistance and high in price, and a special frame is required for installation and use; in general, there is currently a lack of a better, simpler bicycle transmission in the market.
