Steering system and key technology trends
And so on. . EPS system technology trends can be attributed to the following: (1) electric drive technology: EPS system requires the motor terminal voltage is low (typically 12V car battery or 24V), low speed, relatively high output torque, small size . As the motor terminal voltage is low, while the power is relatively high so the motor current is high, which gives the drive unit of the electronic devices and circuit design choice to bring certain difficulties. (2) non-contact sensor technology: EPS system, steering wheel torque sensors require simple,[link widoczny dla zalogowanych], reliable, cheap, moderate accuracy. Taking into account the reliability issues, the current number of foreign non-contact, and contact (such as the sliding resistance) sensor is seldom used. (3) Steering control: As the EPS system in the original machines' mechanical steering system to increase the motor and reducer, making the steering bodies of the inertia increases, this need to control the introduction of inertia and resistance control. System,[link widoczny dla zalogowanych], help to avoid the beginning and end of the motor when power steering impact. Meanwhile, to get a better \contact and mutual restraint in the organic whole, a subsystem when the vehicle is changed, the vehicle produces a corresponding change in performance. Therefore, the need for EPS system and other subsystems on the car to match, in order to facilitate to optimize vehicle performance. 2001 (5) Total 141 95 Light Vehicle Technology technical aspect, and other current international steering gear manufacturers to respond to changing market needs, reduce production costs, enhance the competitiveness of products, without exception, to organize series production of products, Some plants produce a series of the same structure, different structures of some plant several series. Speed by changing the ratio of major structural change parameters, change the work of hydraulic power steering gear and other methods to generate serialization products. Of passive safety technology, the security can absorb impact energy absorbing steering column and steering wheel deformation. More typical of a bellows CRUSHING steering column, energy absorbing steering column grid, with double-tube steel ball safety steering column and so on. With the rapid development of electronic technology, electronic technology in automobiles will be widely applied. Vehicles, electricity consumption has doubled and redoubled,[link widoczny dla zalogowanych], the existing vehicle voltage 12V or 24V, have been unable to meet the vehicle requirements. Europe, America and Japan has started studying 42V vehicle electrical. For the future use of electronic control of electric power steering system, which all electrical components has begun research and development. It is also worth noting that the future trend. U.S. auto rapid development of remote communication devices, remote communication, according to a U.S. research company, in its report \dollars. This is because car manufacturers are actively using this device in order to achieve their strategy in the automotive market discrimination objectives. Vehicle safety and vehicle manufacturers the user a question of common concern, the use of remote communication devices is to improve vehicle safety is an important measure in the future, car manufacturers will} hot day line, Internet and information services {Introduction to the existing security devices combining to go. GM's Onstar away one by one carbon nanotube blood of the 21st century, new materials, processing with ultra-fine nano-technology, the tubular carbon molecules into carbon nanotube array is compelling new materials such material by changing the carbon molecules structure, improve its conductivity, or the formation of a large number of hydrogen features. Successful development of this technology will facilitate the miniaturization of portable computers and electric cars practical. Use of its new electrical characteristics tI Du may be considered in the next generation of high brightness, large screen displays the main components - the components on the electron emission; listed properties with its large number of hydrogen may also be put in electric vehicles equipped with hydrogen storage me doing security,[link widoczny dla zalogowanych], small. Japan's Showa Denko company through the use of special catalyst synthesis, the successful mass production of carbon molecules are arranged in a 150-way communications services leader in this industry, and its end in 2000 with Lu to 100 million. Onstar's success prompted other car makers are expected to provide remote communications services to 2005, 84 new cars will be equipped with remote communication devices,[link widoczny dla zalogowanych], and accept long-distance communication services will reach 1,700 million by lE. (Ma Jian) 200 tubular carbon nano materials (VGcF). VGCF computers and terminals extended life lithium battery Jazz to make equipment more compact. The company's Technology Division President of Orange of the Fang Yan said their goal is the diameter of about 2O nm nanotubes (King-Wah Chiu)
