Description
Technical Field
The invention relates to an automobile, in particular to a method for improving the cost performance of a new energy automobile and an automatic transmission automobile.
Background
The new energy pure electric vehicle, the hybrid electric vehicle and the fuel cell vehicle have many advantages, the advantages are basically similar, and the disadvantages respectively have various disadvantages, but the common disadvantages are high price and low cost performance, and the development of the new energy vehicle industry is seriously hindered.
The heart of the electric automobile is a motor driving system which consists of a motor, a power converter, a controller, various detection sensors and a power supply (storage battery). The motor driving system is to be fully exerted, and the gearbox of the chassis transmission system matched with the traditional automobile structure is simulated.
In order to provide a transmission case matched with a new energy electric vehicle transmission system, according to data display, a single-stage speed reducer is mostly adopted in a pure electric vehicle and a fuel cell vehicle in a series mode of the existing new energy electric vehicle, so that the energy consumption requirement is improved in the future or the new energy electric vehicle is developed into a multi-stage speed reducer; the parallel mode is mainly characterized in that the existing automatic gearbox is adopted for transformation or an electric drive axle is used; the hybrid mode mostly adopts a special hybrid gearbox. In recent years, new transmissions such as two-speed transmissions, coaxial transmissions, transmissions integrated with an electronic disconnect differential, transmissions integrated with a dual clutch differential, three-in-one assemblies of motor controller transmissions, transmissions integrated with an engine motor generator, and the like have appeared. As can be seen, the existing new energy electric automobile gearbox is very complicated.
The technical problem that a gearbox of a new energy electric vehicle is bypassed is unknown, and the fuel engine automobile cannot meet various power requirements of starting and accelerating the vehicle from 0 to overtaking at a high speed of 120km/h, so that the gearbox is matched, the electric vehicle driving motor can output all torque from 0 rotating speed until the constant power output is kept before the highest rotating speed, and the motor seems to have no problem naturally, so that almost 99% of pure electric vehicles in the market at present do not have matched gearboxes capable of shifting.
It is known that, in order to drive a vehicle, the active torque generated by the vehicle is greater than the resisting torque from the outside; the product FL of the force F and the force shoulder L is called moment, and the moment can be increased by increasing the force F or increasing the force shoulder L; the moment required by the automobile for starting and climbing is large, and the moment required by the automobile on a flat road during running is small; obviously, the torque of the fuel engine automobile matching gearbox is increased and reduced by increasing and reducing the force shoulder L in a gear ratio changing mode, and the torque of the pure electric automobile without the matching gearbox is increased or reduced by increasing or reducing the force F through the driving motor. If the automobile transmission system can output larger torque, under the condition that the power can meet the torque and the highest speed requirement required by automobile starting and climbing, torque is required to be stored instead of power.
Once the motor is fixed, the force arm of the motor is fixed, the motor with certain power is known from a relational expression of power P, force F and rotating speed V, the power needs to be increased when the rotating speed is high and the force needs to be large, the power of a driving motor, the capacity of a fuel cell and the capacity of a storage battery need to be increased, the high-power motor is replaced, more batteries are installed, larger power is reserved, the energy efficiency is reduced, the driving motor, the fuel cell and the storage battery are the most core parts of the electric vehicle, and the cost is increased certainly and greatly. The method obtains the evidence from the existing pure electric vehicle loading power and selling price matched with the single-speed transmission. Therefore, the fact that the gearboxes capable of shifting gears are not matched is one of the main reasons for lower cost performance of the new energy electric automobile.
The application has the same application date with three patent applications of a baffle type slide sheet machine, a slide sheet type hydraulic driver, a fuel cell baffle type slide sheet air compressor and a device thereof, and the technical problem of the invention is solved on the basis of the research of the three patent applications, so the technical scheme is suitable for the application of the patent.
