Description

Rolling vehicle transmission

The present invention relates to a rolling vehicle transmission for a rolling vehicle.

Press, the common locomotives on the market today are all two-wheel design. However, in the case of such a locomotive, when a large angle turns during riding or when the terrain is tilted, the rider needs to move the center of gravity of the body to stabilize the body to avoid dumping. If you accidentally encounter a collision while riding, it is easy to cause damage due to the body falling over. Therefore, it is possible to install an auxiliary wheel or a three-wheeled vehicle on the rear wheel of a conventional two-wheeled locomotive.

However, in the conventional three-wheeled locomotive, most of the rear wheel transmissions are driven by the engine to drive the chain, and the chain drives the gear to rotate, and the gear drives the tire to rotate to drive the locomotive forward. In the conventional three-wheeled locomotive, the chain and the gear are exposed to the air, so the rust and aging are easily generated by the sun and rain, and the dirt or debris is liable to adhere to the chain and the gear, thereby causing the chain to relax or the chain of the chain. The failure and the lack of service life.
