Description

Riding vehicle of having multiple axial

The present invention relates to a ride mechanism having a multi-axis drive unit that allows the occupant to naturally climb uphill with a gentle slope because the driving force is expanded and transmitted to the final sprocket during the stepping of the lever pedal with a small force. will be.

More specifically, the multi-axis drive unit can be used to drive the ride mechanism with less effort because the pedal effort of the lever pedal is transmitted directly to the final gear after passing through a plurality of drive gears rather than directly to the rear wheel sprocket which drives the rear wheels. It relates to a ride mechanism having.

In general, the pedal force applied to a ride mechanism pedal such as a bicycle is directly transmitted to a rear wheel drive sprocket connected to the pedal to rotate the sprocket, and the rotational force of the sprocket can move the ride mechanism forward and backward.

As described above, a riding mechanism in which the pedaling force applied to the pedal is directly transmitted to the rear wheel driving sprocket and drives the riding mechanism requires a large stepping force to drive the rear wheel driving sprocket after boarding the riding mechanism. In particular, when a child climbs an uphill road, a greater effort is required, and the user's troubles are doubled and he / she descends from the chair and pulls a ride (eg, a bicycle).

With this in mind, the geared ride mechanism allows the driver and the rear sprockets to be equipped with multiple sprockets with different diameters to select low and high gears to reduce the amount of effort applied to the pedals. Reducing the effort.

The above-mentioned geared ride mechanism is provided with a plurality of sprockets having different diameters in multiple stages on the ride frame and the rear wheel so as to reduce the effort of the user by varying the pedal effort. As it is formed so as to drive the ride mechanism by driving, the cost cost is increased due to the increase in the number of parts, the price of the ride mechanism is expensive, the price competitiveness is lost.

In addition, when the gear shifting is carried out while riding in the riding mechanism, the power transmission is interrupted because the position of the chain is not smoothly shifted with respect to the sprocket, and when the chain shifts from the sprocket during shifting, the driveability Falling, the user has a problem to bear the inconvenience.

In addition, when the gear ratio of the driving sprocket and the rear wheel sprocket is large, it takes a lot of force to step on the pedal because the rotational force is directly applied to the small gear from the standby gear, especially when climbing uphill with a high gear selected. There is a problem that occurs.

It is an object of the present invention to provide a ride mechanism having a multi-axis drive unit having a cost competitiveness by reducing the cost cost due to the simplified structure of the power conversion gear mounted between the lever-type pedal and the final sprocket and outputting a large driving force with less effort. Is in.

Another object of the present invention is to provide a user convenience by easily operating a power conversion gear that outputs a large driving force with a small effort, and has a multi-axis driving unit which can improve the driving performance by preventing the chain from falling off while driving. It is to provide a ride.

It is still another object of the present invention to provide a riding mechanism having a multi-axis driving unit that can be driven at high speed with little force, can be easily driven uphill, and can be utilized practically in real life or leisure life.
