Technical Field

The invention belongs to the technical field of traffic appliances, and particularly relates to a motor tricycle using a pedal motorcycle infinitely variable speed engine as power.

Background

Currently, the closest prior art:

in electric tricycle and motor tricycle, lack a motorcycle type and can be fine adaptation mountain area rural breed family or the middle-aged and the old and women of town and country joint portion, and disabled person, especially to the trip demand of the old or the woman that mechanical operation can't understand the comprehension. People need a tricycle which is extremely simple to operate, sufficient in power, strong in cruising ability and low in use cost as a transportation or travel tool due to the requirements of production life or close-distance leisure travel.

The electric tricycle on the market at present only needs to be screwed to walk although the operation is very simple, has wide application range in the region with a flat road, and has the advantages of low use cost and simple maintenance. However, when the vehicle is used in a mountain area with steep roads, the power of the motor and the capacity of the battery are limited, so that the load climbing capacity is limited, the motor and the controller are frequently damaged due to overlarge current of the vehicle with steep roads in the mountain area, the service life of the battery is greatly reduced, the prices of the vehicle to be repaired and the battery to be replaced are high, and the long-term use cost and the maintenance cost of the vehicle are far higher than those of a fuel vehicle. In addition, motor tricycles on the market at present do not adopt a motorcycle engine with gears for vehicles with the displacement from 110CC to 300CC or even larger. Most drivers of large-displacement freight three-wheeled motorcycles are young and old men, and the gear operation and the matching of the accelerator and the clutch of the three-wheeled motorcycle can be used skillfully. Although the small-displacement motor tricycle suitable for household and short-distance leisure travel has a vehicle type adopting an automatic clutch engine, the operation difficulty is reduced to a great extent, most of the tricycle users are family women, old people and disabled people, and one part of the tricycle users have low comprehension capability or culture level, the motor tricycle with gears cannot be skillfully operated, different gears cannot be used according to different road conditions and vehicle speeds, and the motor tricycle is frequently driven by adopting a low-gear large-throttle mode, so that the oil consumption is too high, and the engine is frequently damaged due to overhigh temperature or insufficient lubrication caused by long-time high-speed operation; or the high gear is loaded to go up the slope and start, which often causes the flameout of the engine or the burning of the clutch plate, and the cost of the maintenance or the replacement of the engine greatly increases the use cost of the motor tricycle.

In addition, when the current motor tricycle is used in a mountain area with a steep slope, because the running speed is low, cooling airflow can not effectively radiate heat for the engine, in order to ensure the heat radiation effect, many motor tricycles adopt an electric fan to radiate heat by forced air cooling, or a water cooling heat radiation system with the electric fan can ensure the heat radiation, but because the electric fan has high power consumption, the electric quantity generated by a magneto of the engine is insufficient, so that the electric quantity of a starting battery is reduced, the case that the engine can not be started frequently occurs, and the convenience of the use of the vehicle is greatly influenced.

In summary, the problems of the prior art are as follows:

the difficulty of learning, using and daily driving of the existing motor tricycle is too large, abnormal abrasion and damage of an engine caused by improper operation of a user are easy to occur, and the use and maintenance cost of the motor tricycle is increased;

the difficulty of solving the technical problems is as follows:

the majority of users of the small-displacement motor tricycle are middle-aged and old people and women in remote mountain areas, rural breeding families or urban and rural junctions, or disabled people, and the income of the users is low, the purchasing power is limited, so the selling price of the motor tricycle cannot be too high. Because the small-displacement motor tricycle is low in selling price and low in profit of manufacturers, the AT automatic transmission similar to that used on an automatic transmission automobile cannot be adopted, and the small-displacement motor tricycle is high in price, complex in structure, difficult to maintain and high in development risk.

The significance of solving the technical problems is as follows:

be applied to domestic small discharge capacity motor tricycle that carries thing, short distance leisure trip, can be like domestic kart, to the direction development of operation fool-proofing, automation, adopt automatic clutch, automatic speed change, its operation driving mode can be more close electric tricycle, twists just to walk, increases the simplicity of operation.
