Oil-electric hybrid power hub motor unit

The present invention relates to a combination of a carrier hub motor and an engine power, so as to save energy and reduce carbon, and to provide a battery for power supply to the hub motor, when the vehicle is driven by an engine or idling, the hub motor The battery is back-charged, so that the battery can be fully charged and the power supply can be provided with long-term power.

With the rise of oil prices, how to effectively use the shortage of energy is a topic that has been widely discussed, and because global environmental pollution and carbon dioxide emissions are becoming more and more serious, countries around the world are actively working to reduce the pollution of steam locomotives and encourage people. The use of hybrid or electric vehicles with a green concept, while the motor is increasingly used in life, its high efficiency energy conversion efficiency is more than 80%, much higher than the engine engine can provide up to about 30% limit, Providing a better option for vehicle power, the motor will have the opportunity to replace the engine as a new generation of vehicle power source.

Therefore, there are many motor-powered vehicles, including composite power vehicles, plug-in hybrid power, electric vehicles, etc., of which pure electric vehicles are developed in the advanced countries of the world, electric steam locomotives The development has made great progress, but the battery technology has not been able to achieve breakthrough development. Therefore, the battery life and charging problem of electric steam locomotives have always been criticized. In addition, the hybrid vehicle is defined as a hybrid power source vehicle, for example, Toyota. Prius, Each has an internal combustion engine, a power motor and a battery, and can drive in a motor mode at low speeds, but its battery capacity is small. If the power is exhausted, it must still be powered by the engine and provide power generation at the appropriate time to recharge into the battery, even if It is not fully electric, but it has been able to save on gasoline consumption.

In addition, two-wheeled vehicles such as locomotives also have related developments in oil-electric hybrid power, in particular, a wheel motor is mounted on the wheel, and then a power connection is made to the engine through the clutch device, wherein the hub motor is a back-electrostatic DC brushless motor. The motor is designed directly on the rim. It is also called the in-wheel motor or the rim motor. It is composed of a stator and a rotor. The surface of the rotor is glued or broken into a permanent magnet. The stator is composed of coil windings. The characteristics of low speed and high torque are the same as those of the outer rotor generator. The hub motor is extended by the direct drive outer rotor structure. The design of the gearless box can reduce the use of the transmission structure, which can effectively reduce the mechanical structure loss and improve the motor efficiency. Further energy saving effects can reduce noise problems and maintenance time.

Therefore, the combination of the engine and the hub motor allows the hub motor to be driven while driving on a gentle road in the urban area, which not only reduces the consumption of gasoline energy, but also reduces noise and exhaust emissions; or switches to the engine. When driving, the two-wheeled vehicle can be used for a longer journey.

However, when the hub motor is converted into engine power, the chain that drives the wheels at the hub motor may generate a large starting torque at the start-up, causing noise and jitter, and the second-wheel carrier is driven by the hub motor. After consuming the power of the battery, the battery will have a problem of insufficient power. Although it can be converted to be driven by the engine, the problem of insufficient battery power must wait until the place where it can be charged. After charging, the hub motor can be used again. This causes inconvenience to the rider.

The reason is that in order to improve the aforementioned known hybrid electric vehicle, there is noise and jitter during power conversion, and there is no problem such as charging when the battery power is insufficient. The present invention provides a coaxial end side end coaxial of the hub motor. Wearing a sprocket, and having a plurality of cushions on the inner end ring of the sprocket, and inserting the cushion into the recessed groove of the end cover, so that the sprocket and the end cover are engaged, thereby allowing the engine of the vehicle The power can be transmitted through the chain, so that the power transmission jitter and noise can be greatly reduced. At the same time, the vehicle can be switched to be driven by the electric motor of the hub motor, and the wheel can be driven when the carrier is idling or driven by the engine. The motor becomes a generator and charges the battery.

The technical solution adopted by the novel to solve the technical problem is that a hub rotor with an end cap and a brake drum is disposed at the center of one wheel, and the hub of the hub is provided with a simultaneous shaft at both ends thereof. The end cover and the stator of the shaft portion on the brake drum, and the end surface on the outer side of the end cover is provided with a concave portion having radially spaced ribs therein, and a hub portion of the sprocket shaft is disposed on the shaft portion of the stator The sleeve is sleeved in the recess, and the end faces of the hub of the sprocket are protruded from the plurality of cushions which are annularly spaced apart, and the cushions are formed to receive the recessed portions between the adjacent ribs.

Therefore, the sprocket and the end cover are tightly disposed on the shaft portion of the stator of the above-mentioned novel hub motor through the cushion on the sprocket on the end cover side and the recessed portion corresponding to the end cover. The snaps together enable collision and noise between the parts due to power conversion when the switching power is driven by the engine, and also the vehicle is driven by the engine or idling, which enables the hub motor to generate electricity to charge the battery.

Referring to FIG. 1 to FIG. 4 , the hub motor B of the present invention includes a wheel hub 1 having a hub A disposed therein, and a plurality of magnet blocks 11 are arranged in a ring shape on the inner side of the hub rotor 1 , and the hub rotor 1 is arranged. The two sides cover the end cap 2 and the brake drum 3 respectively fixed to the same central axis, and at the same time, a coaxial assembly is arranged in the center of the hub rotor 1 and the stator 4 of the array coil is wound around the outer edge thereof, and the center of the stator 4 is repeated. The shaft portion 41 which is extended to both sides and fixed to the frame body is disposed, and the shaft portion 41 is passed through the bearing provided at the center of the end cover 2 and the brake drum 3 to reinstall the outer side of the brake drum 3 A brake device 5 is provided, and a recess 21 is provided at the outer end surface of the end cover 2, and a plurality of ribs 22 are radially spaced at the bottom portion of the recess 21 so that the adjacent ribs 22 are provided. A groove portion 23 is formed therebetween, and then a sprocket 6 shafted on the shaft portion 41 is disposed, so that the hub portion 61 of the sprocket is received in the recess 21 of the end cover 2 while the end surface of the hub portion 61 is A plurality of cushions 62 are provided in the annular space, and the gaps between the adjacent cushions 62 are arranged to correspond to the ribs 22, The punching pad 62 is accommodated in the corresponding recessed portions 23, so that the sprocket 6 and the end cover 2 are assembled together.

Next, the sprocket 6 is wound by the chain 7 of the engine power output of the vehicle, that is, the power output from the engine can also drive the sprocket 6 to rotate through the chain 7, and the wheel A is driven by the hub rotor 1 via the end cover 2. Turn to let the vehicle travel.

Therefore, when the two-wheeled vehicle is driven by the electric power of the battery, that is, electric power is input from one end of the shaft portion 41 of the stator 4 to cause a current to enter the coil to generate a magnetic field, and the magnetic effect of the current is utilized. The hub rotor 1 produces continuous rotation, which in turn drives the wheels to rotate and the carriers travel. Therefore, the vehicle can be driven by electric power alone, so that noise and exhaust gas emissions can be reduced, and the purpose of gasoline energy consumption can be reduced.

Conversely, the travel distance that can be provided by simply driving the vehicle with electric power is short. If you want to travel longer distances, or when the battery is exhausted and cannot drive the vehicle, you can pass through the engine of the vehicle. The switching of the clutch allows the vehicle to be driven by the engine. Although the vehicle is not fully powered, the fuel-electric hybrid power can also achieve the purpose of saving gasoline consumption.

In addition, when the carrier of the novel hub motor is installed, when the engine is driven, or when the carrier is idling, when the hub rotor 1 is still rotating, the hub motor is like the outer rotor generator. The ability to generate electricity allows the hub motor to charge the battery instantaneously through the control of the controller at the moment of power generation. Therefore, the hub motor can be used as a generator to provide regenerative power generation, so that the hybrid electric vehicle can be used. The battery can recharge the battery without any external power, and thus the battery power is sufficient, or the battery can be provided with a long-term power supply.
