Oil-electric dual power conversion device for three-wheeled motorcycle

Abstract

The invention discloses an oil and electric dual-power conversion device of a tricycle. The oil and electric dual-power conversion device of the tricycle comprises a shell, a driving motor and an installation seat, wherein the installation seat comprises a first installation plate and a second installation plate which are perpendicular to each other and are fixedly connected with each other, the shell comprises a front half shell and a rear half shell, the front half shell and the rear half shell are fixedly arranged on supporting columns arranged on the first installation plate, the front half shell supports a first input shaft through a first bearing seat, the rear half shell supports a conversion device output shaft through a second bearing seat and a bearing, one end of the first input shaft and one end of the conversion device output shaft in the shell are connected through a one-way clutch, a basin gear is fixedly arranged in the circumferential direction of the conversion device output shaft, a rotating shaft of the driving motor is a second input shaft, a bevel gear shaft is fixedly arranged in the circumferential direction of the second input shaft, and the bevel end of the bevel gear shaft stretches into the shell and is engaged with the basin gear. The oil and electric dual-power conversion device of the tricycle has the advantages that the structure is simple, the assembling is easy to conduct, the shape of the original engine or the rear axle does not need to be changed, the power switching operation is facilitated, the production cost is not increased and the cost performance is high.

Description

technical field [0001] The invention relates to the field of power conversion of three-wheel motorcycles, in particular to an oil-electric dual power conversion device for three-wheel motorcycles. Background technique [0002] Traditional three-wheeled motorcycles include conventional gasoline, diesel-powered fuel motorcycles, and electric motor-powered motorcycles. Fuel motorcycles are very noisy and have high exhaust emissions during operation, which is not environmentally friendly. Moreover, three-wheel motorcycles are mostly used as agricultural vehicles. In recent years, oil prices have risen year after year, and the cost of using fuel motorcycles is too high. Adapt to the needs of the countryside. Although the manufacturing and operating costs of electric motorcycles are low, the motor temperature is too high and the motor is easy to burn when the road conditions are bad (climbing, heavy load), and the power is small, the driving speed is slow, and the continuation ab...

Problems solved by technology

The fuel-driven and electric-driven conversion of a hybrid three-wheeled motorcycle is realized by an oil-electric dual-power conversion device. There are mainly two types of existing power conversion devices, one such as the invention patent with the patent No. The device does not have a gear switching device. The engine and the fuel engine are connected to the power of the rear axle. When using one of the powers, only the power is activated. This power conversion device is likely to cause interference between the two powers during use and damage the fuel. Engine or electric motor, and the power connection between the rear axle and the fuel engine and electric motor must be cut off during power conversion, which is extremely inconvenient to switch

[0004] There is also an invention patent such as application number 201310103116.3. This power conversion device relies on the fork to toggle the clutch to switch gears. This dual power conversion device needs to be equipped with a clutch and a shift fork in the housing. Space, there are shortcomings such as complex structure, large volume, difficult assembly, high production cost, cumbersome operation, and poor reliability

Moreover, this power conversion device needs to be installed on the engine or the rear axle, which takes up a lot of space, resulting in insufficient installation space on the three-wheeled motorcycle frame, so it is necessary to change the shape of the original engine or the rear axle, or even the three-wheeled motorcycle. The shape of the frame, therefore, the original engine or rear axle, or even the three-wheeled motorcycle frame needs to be re-cast, which greatly increases the production cost and reduces the cost-effectiveness of the three-wheeled motorcycle

[0005] The output shaft of the gearbox of the fuel-powered three-wheeled motorcycle and the input shaft of the rear axle are all arranged longitudinally along the three-wheeled motorcycle frame usually, and the first input shaft of the existing power conversion device, the conversion device output The shafts are not on one axis, so that the existing fuel-powered three-wheeled motorcycles cannot be converted into hybrid three-wheeled motorcycles by adding a power conversion device, which limits the application range of the existing power conversion device. limitations
