不使用汽油內(nèi)燃機不僅減少排放，它也將有更多的選擇對車輛實行電子控制。
一種新的體系已經(jīng)設(shè)計完成，它整體集成了傳動系統(tǒng)，轉(zhuǎn)向器，減震器和直接置入汽車車輪里的剎車裝置，取代原有的帶有液壓減震器的傳統(tǒng)車輪懸架，機械式轉(zhuǎn)向器，液壓制動裝置和普通電動馬達，這種設(shè)計提高了燃油里程，更加安全、方便。
這個被稱為“ecorner”的電動汽車概念系統(tǒng)，西門子VDO公司期望它允許傳統(tǒng)引擎架構(gòu)被電動輪轂電機取代，這種電機將會直接作用于車輪來加速車輛。四個輪轂電機將獨立運作，提供極富動力的駕駛性能。
“ecorner”電動汽車概念系統(tǒng)，將使得開發(fā)傳動系統(tǒng)，轉(zhuǎn)向系統(tǒng)和剎車裝置共同為司機提供支持的車輛成為可能，在危急駕駛的情況，幫助司機避免意外事故。
電動機
有了“ecorner”系統(tǒng)，電動機將確保車輪和路面接觸。有了新的懸架，可以減除液壓轉(zhuǎn)向系統(tǒng)，每個單獨的車輪可以被移動到它自己的特定轉(zhuǎn)向角。當車速降低時，輪轂電機作為輔助剎車，可以起到發(fā)電機的作用，用這種方式創(chuàng)造的能量可以用來給車用電池充電。最后，除了電機制動以外，電子楔塊剎車裝置能夠以最大的精確度和巨大的制動力使每個車輪獨立減速。
西門子VDO汽車集團副總Klaus Egger博士說：“混合動力驅(qū)動只是未來推進方案道路上的一個中間步驟，我們認為電動機將會成為現(xiàn)實長期的驅(qū)動動力的解決方案，因為它能夠滿足未來最嚴格排放法規(guī)要求?！?/SPAN>
從內(nèi)燃機汽車到智能電動車的完全改變，給駕駛員和汽車制造商都帶來益處。預計使用輪轂電機后用于汽車推進的能量可以達到總能量的96%。這將使得汽車制造商更容易滿足排放法規(guī)，同時為顧客提供極富動力的車輛，并且具有優(yōu)良的燃油經(jīng)濟性。
該系統(tǒng)給駕駛員帶來了各種可能。利用電動轉(zhuǎn)向助力和控制每個車輪的加速度，能夠使車輛在危險狀況下更加穩(wěn)定。車主的成本也將降低，因為使用更少的部件、減除了液壓系統(tǒng)，將減少磨損，并使得保養(yǎng)更加簡單。
該系統(tǒng)因為不再需要中心電機從而展現(xiàn)了其在汽車設(shè)計革新方面的潛力。
Eliminating internal combustion engines that burn gasoline will not only reduce will also increase the options for controlling vehicles electronically.
A new system has been designed to integrate drivetrain,steering, shock absorbers and brakes directly into the wheels of cars. Replacing conventional wheel suspension with hydraulic shock absorbers,mechanical steering,hydraulic brakes and an electric drive motor,the design promises improved fuel mileage,enhanced safety and greater convenience.
Siemens VDO expects its system,called ecorner,to allow traditional engine architecture to be replaced by electric wheel hub motors,which act directly on the wheels to accelerate the car. The four wheel hub motors will operate independently,offering extremely dynamic driving.
The ecorner system will make it possible to develop vehicles in which drivetrain, steering and brakes provide common support for the driver in critical driving situations, helping to avoid accidents.
Electric motors
With ecorner,electric motos will ensure contact between the wheel and the new suspension, hydraulic steering can be eliminated and each individual wheel can be moved to its own specific steering the speed is reduced,the wheel hub motors act as auxiliary brakes using a generator rgy created in this manner can be used to charge the vehicle y,in addition to the generator brakes,the electronic wedge brakes can decelerate each wheel separately, with maximum precision and enormous braking power.
Egger, group vice president of Siemens VDO Automotive says:"Hybrid drives are only an intermediate step along the path to future propulsion solutions. We consider the electric motor to be the actual long-term drive solution for fulfilling even the most stringent emission laws of the future."
The changeover from cars with internal combustion engines to intelligent electric vehicles will bring benefits for drivers as well as manufacturers. Wheel hub motors are predicted to use up to 96 per cent of their electrical energy for vehicle will make it much easier for automobile manufacturers to satisfy emissions regulations,while simultaneously offering extremely dynamic vehicles with excellent fuel economy.
The system opens up new possibilities for electronic steering aids and controlled acceleration of individual wheels will enable better vehicle stabilisation in hazardous costs for car owners will also be reduced , as using fewer components and eliminating hydraulic systems will reduce wear and service complexity.
The system also has the potential to revolutionise vehicle design by eliminating the need for a central motor.
