Description
Technical field
The utility model relates to a kind of power actuated vehicle, specifically a kind of wind direction control system of power actuated vehicle.
Background technology
Along with the rapid growth of this several years China's economics, the people take in and continue to raise, and people buy the desire of car strengthening, and in 5～10 years from now on, will be the peak load conditionss that the Chinese citizen buys automobile, are also the critical periods that can Chinese Automobile Industry ' be developed.In addition; along with energy shock; the impact of China's entry into the WTO etc., the auto-industry of China also have been subject to very large challenge, at these opportunities and challenges and crucial moment of depositing; conscientiously improve the performance of the automobile of Chinese Automobile Industry '; resolve fuel-economizing and the high speed stability characteristic (quality) of automobile, reduce the cost of automobile, energy savings; this will win the market, and improves greatly simultaneously world's competitiveness of Chinese automobile!
Present stage, performance and external many major companies of automobile of China also had very large gap, especially for the integral design of automobile, and the design aspect of energy-saving and emission-reduction gap is larger especially.So we are necessary carefully to analyze the production model of China Automobile Industry and the Production design technology of automobile in the face of huge challenge, thus the competitive power of effective and favourable raising Chinese Auto Industry.And for modern automobile, power index, fuel economy index and safety indexes etc. are all to weigh the important indicator of an automobile quality.So it is just of crucial importance to improve these performances of automobile, thus the variable chassis control system that we propose just such resistance to motion that effectively reduces automobile by the chassis structure that changes automobile reach the mechanism of effective reduction oil consumption purpose.
Know that resistance suffered in vehicle traveling process is divided into rolling resistance, air resistance, gradient resistance and resistance due to acceleration four parts by analyzing us.In above-mentioned all resistances, air resistance and rolling resistance all exist under any driving conditions, and grade resistance and resistance due to acceleration only exist under certain driving conditions.Just there is no grade resistance and resistance due to acceleration during constant-speed driving on horizontal road.Air resistance is divided into again pressure resistance and friction drag two parts.Friction drag is the component on travel direction of making a concerted effort of the tangential force that produces at bodywork surface due to the viscosity of air, and this part resistance accounts for 9% of total air resistance.pressure resistance is divided into again form resistance, interference drag, interior circulation resistance and induced drag, wherein form resistance account for pressure resistance most of approximately 58%, and the design of modern teardrop body can weaken this resistance greatly, next is interference drag, it is mainly that protrusion by bodywork surface is (as back mirror, door knob, gutter, the suspension pilot bar, axle drive shaft etc.) resistance that causes accounts for 14% of total drag, engine cooling system, flow through car body inside of the required airs such as ventilation of body is that the resistance that consists of is called interior circulation resistance and accounts for 12%, induced drag is the vertical equity component that air lift force produces, this part accounts for 7%.So the appropriate design vehicle body all has a great impact reducing air resistance raising economy and stability! In addition, fuel economy and safety are two very important contents of current automobile industry development, are main directions of development of automobile from now on.But due to present automobile design produce complete after, can't change again the factors such as its shape, thereby the factor such as its air resistance just can't change also.This just makes under the different operating mode such as high speed and low speed, and automobile all travels at identical aerodynamics state.Its fuel economy and safety can not reach Best Point naturally under each operating mode.So we are by finding that to the analysis of the vehicle body of automobile common is fixedly that the chassis can not reach desirable optimum air dynam requirement under difference enforcement operating mode, so we have proposed variable chassis control system to realize in different road conditions, realize reaching the dynamic (dynamical) target of optimum air by the chassis structure that changes automobile under different driving conditions, the impact of automobile is realized the optimization of automotive body structure thereby effectively reduce air resistance.
