Description

Two shift transmission used for electric vehicle
Technical field
This project is related to a kind of two shift transmission used for electric vehicle, belongs to automobile technical field.
Background technology
With increasingly serious and traditional fossil energy the increasingly depleted of environmental problem, hair has worldwide been started Open up the industry tide of electric automobile.In " 13 planning ", construction " industry 4.0 " and realization that China formulates《Made in China 2025》In Deng National strategic planning, clear and definite electric automobile is that China's new-energy automobile development is main with auto industry transition Strategic decisions.
Drive technology is the core technology of electric automobile, its dynamic property and economy for directly determining automobile.At present, city Electric automobile on sale mainly matches single gear decelerator on field, although it has simple structure, small volume, light weight, need not change The advantages of gear is so as to power failure-free, but have the following disadvantages：
1) it is higher to motor performance requirement.The characteristic of motor be low turn it is permanent turn round, height turns invariable power, in order to allow vapour Car possesses good grade climbing performance and acceleration, and the decelerator gearratio of single gear than larger, thus can be travelled in middle speed high In the case of, the rotating speed of motor can be very high, and abrasion and the noise of motor can aggravate.Therefore it is required that motor is needed Possess good speed adjusting performance and mechanical performance, this often increases the volume and manufacturing cost of motor.
2) it is less efficient.Because single transmission is than generally cannot simultaneously take into account the dynamic property and economy of electric automobile, OK Motor most cases cannot be in efficiency operation point during sailing, especially in highest or minimum speed and underload Under the conditions of, motor efficiency can typically be down to below 60-70%, serious waste vehicle-mounted electric energy and reduce course continuation mileage.
Due to the limitation of current battery technology, the course continuation mileage of electric automobile is extremely limited.In order that electric automobile can be more Its superiority is played well, while reducing the requirement to motor and battery, electric drive system for electric vehicles should be using many gears Speed changer.Ensure that motor can more be operated in ideal high efficiency region by manipulating multi-shifting speed variator, So as to improve the index such as dynamic property, economy of vehicle.
Compared to more gears even continuous variable transmission, two shift transmissions are simpler compact due to structure, and power is close Du Genggao, technology relative maturity, manufacturing cost is relatively low.And the shift transmission of electric automobile two of main flow is main in the market It is mechanical transmission, because power can be interrupted, synchronizer shift time is more long in its shift process, vibration noise outstanding problem etc. Reason, the comfortableness of gearshift is poor with dynamic property, reduces the market competitiveness of electric automobile.Thus, development shifting power is not Interruption, the great market value of two shift transmissions that shift time is short and vibration noise is small.
The content of the invention
It is an object of the invention to provide a kind of two speed transmission used for electric vehicle, deposited with solving existing single gear decelerator The low problem of motor efficiency comparison during the high, traveling to motor requirement, increases electric automobile course continuation mileage, together When ensure shifting power is not interrupted, shift time is short and vibration noise is small, improve vehicle dynamic property and economy, reduce into This, and advance the industrialization of electric automobile.
