Oil-electric hybrid power quadricycle

Abstract

The invention relates to an oil-electric hybrid power quadricycle which comprises a frame, a carriage, a driver seat, a range extending device, batteries, a muffler, an oil tank and a controller, wherein the range extending device comprises a generator, an engine and a clutch, an air duct is arranged in front of the driver seat, the range extending device is arranged below the driver seat, and a motor, a gasoline engine cylinder head and the controller right face to an air inlet. The range extending device is arranged on the frame through a shock absorbing mount which is formed by connecting an upper supporting plate, a lower supporting plate and a middle rubber block. The oil tank is arranged below the driver seat, the muffler comprises a primary muffling tube, a secondary muffling tube and a flexible connector, the secondary muffling tube is arranged on the frame through a hooking part, and the batteries are arranged at the center below the carriage. The oil-electric hybrid power quadricycle has good radiation, small noise and small shock and is provided with the range extending device which has a simple structure and facilitates reduction of torsional vibration load of power.

Description

technical field [0001] The invention relates to an oil-electric hybrid agricultural four-wheel vehicle, in particular to a range extender for an oil-electric hybrid agricultural four-wheel vehicle, in particular to a range extender with a clutch and a cooling and heat dissipation structure. Background technique [0002] With the increasing scarcity of energy and the aggravation of environmental pollution, electric vehicles with energy-saving and environmental protection effects have gradually become the main direction of future automobile development, and extended-range electric vehicles are recognized as one of the mainstream technical directions for the development of electric vehicles. . Extended-range electric vehicles can solve the problems of large-scale industrialization of electric vehicles caused by low storage energy of power batteries, short driving range, and long charging time, and meet the development needs of electric vehicles. Therefore, the gasoline-electri...

AI Technical Summary

Problems solved by technology

Both of the above two connection methods have certain disadvantages. The elastic coupling is used to connect with a large axial dimension, which requires high positioning and installation technology. However, if the rigid connection is directly used, the inertia and dynamic load of the generator will give the shaft system Impact, there is a risk of damage to the shaft system due to dynamic overload

[0003] In addition, the range extender also brings the following problems during the use of the gasoline-electric hybrid agricultural four-wheel vehicle. For example, 1. The electric agricultural four-wheel vehicle itself is basically noiseless. During the driving process, it mainly drives the motor to rotate The sound produced is usually less than 60 decibels; while the electric agricultural four-wheel vehicle with a range extender is noisy, this is because the generator part is powered by a general-purpose gasoline engine, and the industry standard of a general-purpose gasoline engine is usually at 100. around decibels

2. The pure electric four-wheel vehicle basically has no vibration during driving, while the electric four-wheel vehicle with a range extender vibrates strongly. This is due to the strong vibration generated by the piston movement of the internal combustion engine and transmitted to the whole vehicle. Therefore, the user decrease in comfort

3. The generator motor, general-purpose gasoline engine and controller of the electric four-wheel vehicle with a range extender are all heat sources, which cause the temperature to rise, affect the performance of the product, and even cause the entire range device to be burned
