Description
Technical Field
The utility model relates to a power system of a two-wheel driven electric bicycle.
Background
In recent years, electric vehicles have rapidly developed, and besides the traditional electric vehicles and two-wheeled motorcycles, the trend also has developed into the field of special vehicles. Such as dirtbikes, the power system of the dirtbike is also increasingly diversified due to the flexible configuration of the power-driven power system.
Disclosure of Invention
1) Technical problem to be solved
The traditional fuel off-road motorcycle is usually driven by a rear wheel, on one hand, the traditional fuel off-road motorcycle is limited by the layout difficulty of a power system, and on the other hand, the front driving force is poor in performance under the working conditions of ascending, accelerating and the like. But the dual-driving force system formed by the precursor and the rear drive is more advantageous when the vehicle passes through mud, marsh, shrubs, ice and snow and other high-damping and low-adhesion pavements at medium and low speeds. The power system of the electric two-wheel vehicle driven by the double wheels can well solve the problem of high obstacle crossing capability at medium and low speeds and does not influence the high-speed running performance.
2) Technical proposal
The utility model provides a power system of a two-wheel driven electric bicycle, which is characterized in that the rear wheel of the bicycle is driven by a chain, the driving force of the rear wheel is derived from a central motor power system arranged in the middle of the bicycle body, the central motor power system mainly comprises a motor and a transmission system, the front wheel of the bicycle is driven by a hub motor power system, the hub motor power system mainly comprises a motor, a planetary reducer, an overrunning clutch, the motor, the planetary reducer and the overrunning clutch are all arranged in a hub, and when the actual bicycle speed exceeds the speed which can be achieved by the driving of the hub motor, the overrunning clutch acts, and the motor of the hub motor power system does not provide driving force. Because of the function of the overrun clutch, the vehicle has good obstacle surmounting capability at medium and low speeds, and meanwhile, the vehicle has no resistance at high speed running and high speed running performance is not influenced.
The motor of the central motor power system is controlled by one central motor driver, and the motor of the hub motor power system is controlled by the other hub motor driver.
The throttle signals of the middle motor driver and the hub motor driver are connected together and connected to the throttle.
The brake signals of the middle motor driver and the hub motor driver are connected together and connected to the brake.
The gear signals of the middle motor driver and the hub motor driver are connected together and are connected to the gear switch.
Thus, a dual-redundancy power system is formed, which can work together to provide excellent power performance, can also be independently driven, and meets the requirement of high reliability.
The middle motor driver and the hub motor driver are connected together through a CAN bus and communicated through the CAN bus.
The vehicle is provided with a mode selection switch connected to the center motor driver. The central motor receives the mode signal and sends an instruction to the hub motor driver through the CAN bus, so that power distribution in various modes CAN be disabled, and the requirements of different working conditions are met.
The Bluetooth module is arranged on the vehicle and connected with the middle motor driver, so that Bluetooth connection with the middle motor driver can be realized. Through bluetooth connection, the user not only can acquire various operating mode parameters, also can set up multiple power parameter, satisfies diversified demand.
3) Advantageous effects
By adopting the scheme, the vehicle has good middle-low speed ride-through capability and good high-speed performance, can realize high-reliability operation, and can meet the requirement of diversified power modes.
Description of the embodiments
The utility model will now be described in further detail with reference to the accompanying drawings. The drawing is a simplified schematic diagram, only the basic structure of the utility model is illustrated in a schematic way, the rear wheel of the vehicle is driven by a chain 2, the driving force of the rear wheel is derived from a central motor power system 1 arranged in the middle of the vehicle body, the central motor power system 1 mainly comprises a motor and a transmission system, the front wheel of the vehicle is driven by a hub motor power system 3, the hub motor power system 3 mainly comprises a motor, a planetary reducer and an overrunning clutch, the motor, the planetary reducer and the overrunning clutch are all arranged in a hub, and when the actual vehicle speed exceeds the speed which can be achieved by driving of the hub motor, the overrunning clutch acts, and the motor of the hub motor power system no longer provides the driving force.
The motor of the center motor power system 1 is controlled by one center motor driver, and the motor of the hub motor power system 3 is controlled by the other hub motor driver.
The throttle signals of the middle motor driver and the hub motor driver are connected together and connected to the throttle.
The brake signals of the middle motor driver and the hub motor driver are connected together and connected to the brake.
The gear signals of the middle motor driver and the hub motor driver are connected together and are connected to the gear switch.
The middle motor driver and the hub motor driver are connected together through a CAN bus and communicated through the CAN bus.
The vehicle is provided with a mode selection switch connected to the center motor driver.
The Bluetooth module is arranged on the vehicle and connected with the middle motor driver, so that Bluetooth connection with the middle motor driver can be realized.
