The new energy automobile has the advantages of four: energy saving
However, the new energy vehicle has many problems, firstly, the technology is immature, and especially the pure electric endurance cannot meet specific use requirements.
For a new energy pure electric vehicle, the new energy pure electric vehicle can be divided into two parts of unsprung mass and sprung mass. If the unsprung mass is defined below, it refers to the mass that is not supported by the elastic elements in the suspension system, typically including the wheels, springs, shock absorbers and other associated components, while the sprung mass is naturally the mass of the remainder of the vehicle, typically including the frame, powertrain, power storage battery, transmission, occupants, etc., and adding unsprung mass is extremely detrimental to comfort and handling.
For common civil vehicles, some relatively light materials such as aluminum alloy are often used for manufacturing suspended parts so as to reduce unsprung mass and improve the response speed of the suspension, but the unsprung mass of the hub generator is just greatly increased, and meanwhile, the rotational inertia of the hub is also increased, which is unfavorable for the operation performance of the vehicle.
Content of application
The universal joint steel wire flexible shaft is specially used for the universal joint steel wire flexible shaft of the linked wheel drive generator for the endurance of the new energy pure electric vehicle.
The technical purpose of the application is realized by the following technical scheme:
the universal joint steel wire flexible shaft is connected with two axes and two shafts which are not in the same direction or have relative motion through the universal joint steel wire flexible shaft to transmit rotary motion and torque when the wheel rotates, and the rotary motion and the torque can be flexibly transmitted to any position, so that the generator is driven to generate electricity.
Preferably, the universal joint steel wire flexible shaft consists of two universal joints and one steel wire flexible shaft, two ends of the universal joint steel wire flexible shaft are respectively connected with the flange plate, one end of the universal joint steel wire flexible shaft is connected with the wheel axle, and the other end of the universal joint steel wire flexible shaft is connected with the flywheel.
Preferably, the wheel shaft is connected with the flange plate and then is connected with one end of the universal joint steel wire flexible shaft.
Preferably, the flywheel and the generator rotor are connected with the flange plate and then are connected with the other end of the universal joint steel wire flexible shaft.
The application has the following beneficial effects: the generator is arranged on a chassis frame and is linked with a wheel axle by a universal joint steel wire flexible shaft, the rotation of wheels during the running of the vehicle drives the generator to generate electricity by the universal joint steel wire flexible shaft, the universal joint steel wire flexible shaft has the advantages of tropism and bending property, the running of the vehicle has no influence on the generator, passengers and goods when the vehicle runs on bumpy roads, the generator is arranged on the chassis frame, has the advantages of water resistance, shock resistance and dust prevention, the universal joint steel wire flexible shaft for connecting the wheel driving generator mainly solves the problem of short endurance running of the electric vehicle, and can realize various complex driving modes, and because the wheel drive generator has the characteristic of independent driving of a single wheel, the wheel drive generator can be easily driven by the wheel drive generator no matter in front driving or rear driving, and the universal joint steel wire flexible shaft for linking the wheels and the generator is used for realizing the function.
The method has the following specific advantages:
1. simple transmission structure
After the universal joint steel wire flexible shaft of the generator is driven by the wheels, part of storage batteries can be saved, the weight of the vehicle body can be reduced, and the vehicle structure is simple.
2. Flexible driving mode
Because a single wheel has the characteristic of independent driving, the universal joint steel wire flexible shaft is connected with the wheel driving generator to drive the generator in both front driving and rear driving modes.
3. Kinetic energy matching for various vehicle types
New energy motorcycle type adopts the electric drive more or less, therefore the wheel drive generator drive has also been allocated big use field, no matter be pure electric four-wheel car or pure electric two-wheel car.
4. Low energy consumption
After the universal joint steel wire flexible shaft of the generator is driven by the wheels, the energy loss in the power transmission process can be greatly reduced.
5. Saving material
Due to the omission of the transmission system, a large amount of resources, especially some precious metals, are saved.
