Intelligent automatic speed changing hybrid power motorcycle

Abstract

The invention discloses an intelligent automatic speed change hybrid power motorcycle, which comprises a fuel oil / fuel gas generator, an ECU control system, an accumulator, an accumulator charger, a two-shift automatic speed change electric hub with a motor, a motor rotational speed sensing mechanism and a resistance sensing mechanism which are arranged on a vehicle frame; the sensing mechanism converts a driving torque, namely rotational speed and driving resistance, namely vehicle speed signal into an electronic signal and outputs the electronic signal to the ECU; according to the output power of the motor and the driving state of the vehicle, the motorcycle completes conversion of power energy between the generator and the accumulator, reduces emission and avoids the trouble of frequent charging of a user; and the motorcycle adopts the two-shift automatic speed change electric hub, can self-adapt the change of driving resistance and automatically carry out shifting and speed change under the condition of not cutting off driving force, is favorable for high-efficiency energy conservation of vehicle and mechanical power equipment, can further control emission reduction of the vehicle and greatly improve dynamism, economy, driving safety and comfortableness of the vehicle.

Description

technical field [0001] The invention relates to a transmission of a motor vehicle or mechanical power equipment, in particular to an intelligent automatic variable-speed hybrid electric motorcycle. Background technique [0002] In the prior art, motorcycles and electric bicycles basically provide power or energy through fuel / gas engines or storage batteries to complete travel. Motorcycles using engines have been developed for many years, and the technology is becoming more and more mature, but the problems of large fuel consumption and large exhaust emissions cannot be solved always. Now that energy is increasingly scarce, it is necessary to improve the motorcycle powered by a single engine. Although electric motorcycles that use batteries to provide power energy solve the problem of exhaust emissions, due to the limited storage power, it is difficult to reach the order of magnitude of 100 kilometers on one charge, and frequent charging causes troubles for users. In order ...

AI Technical Summary

Problems solved by technology

Motorcycles with engines have been developed for many years, and the technology has become more mature, but the problems of high fuel consumption and large exhaust emissions have not been solved.

[0004]In the situation that the rider does not know the driving resistance, and only operates the speed change device based on experience, it is inevitable that there will be the following problems: 1. When the load is heavy, due to the increase of driving resistance, the motor speed is forced to drop to work in the low-efficiency area, causing the motor to stall, heat up, or even stop rotating when the battery increases the supply current.

2. Since there is no mechanical transmission to adjust the torque and speed, it can only be used in plain areas, and it cannot be used in mountainous, hilly and heavy-load conditions, which reduces the scope of use; 3. The installation space at the drive wheel is small, and it is very difficult to install the motor It is difficult to accommodate automatic transmission and other new technologies; 4. It does not have the function of self-adaptation, and cannot automatically detect, correct and eliminate the driver's operation errors; 5. When the vehicle speed changes suddenly, the motor will be in an unsteady state running, it will inevitably cause the motor power and driving resistance to be difficult to match

6. The continuation distance is short, the climbing ability is poor, and the adaptability range is small

[0005] Therefore, it is necessary to modify the motorcycle, which can automatically switch between the generator and the battery according to the resistance and speed signals, so as to achieve the best match between the power output and the driving conditions of the vehicle, reduce emissions and avoid frequent charging by users. It is troublesome, and can adapt to the change of driving resistance without cutting off the driving force, and automatically shift gears to solve the problem that the motor torque-speed change is small and cannot meet the problem of road use under complex conditions
