Abstract
Compared with a traditional steel vehicle suspension system, air suspension has multiple advantages, and the most important one is that the elastic coefficient, namely the hardness, of a spring can be automatically adjusted as required. For example, the suspension can become hard to improve the vehicle body stability in high-speed driving; and a control unit can consider that a jolt road surface is passed by in long-time low-speed driving, so that the suspension becomes soft to improve the damping comfortableness. In addition, the acceleration generated by the impact on wheels from the ground is one of considered parameters for automatic adjustment of an air spring. For example, the air spring and a damper of wheels at the outer side can automatically become hard to reduce the vehicle body sidesway in high-speed turning; and an electronic module can strengthen the hardness of a spring and a damper of front wheels to reduce the inertia forerake of a vehicle body in emergent braking. Therefore, a vehicle type provided with the air spring has higher control limitation and comfortableness compared with other vehicle types.
Description
Technical field
The height and the soft or hard that the present invention relates to control chassis are harmonious to the unification reaching comfortable and move, and are specifically a kind of variable chassis suspension system designs methods.
Background technology
Compared with conventional steel automobile suspension system, Pneumatic Suspension has a lot of advantage, and the most important is exactly that the elasticity modulus of spring i.e. the soft or hard of spring can regulate as required automatically.Such as, hanging when running at high speed can be hardening, and to improve vehicle body stability, during long-time low speed driving, control unit can be thought through jolting road surface, to hang deliquescing to improve damping traveling comfort.In addition, wheel is subject to the acceleration/accel that ground shock produces also is one of parameter of considering when automatically regulating of air bellow.Such as, when at a high speed crossing curved, the air bellow of outboard wheels and bumper will be automatically hardening, and to reduce the inclination of vehicle body, when emergency braking, electronic module also can lean forward to the inertia that the spring of front-wheel and bumper hardness strengthen reducing vehicle body.Therefore, the vehicle that air bellow is housed has the higher manipulation limit and comfort level than other automobile.
Summary of the invention
Initiatively hydraulic lift system (Active Body Control) built-in electro-hydraulic integration module is the hinge sections of system, can according to the speed of a motor vehicle, the data message of shock absorber stretching frequency and telescopic level, near centre of gravity of vehicle, longitudinal direction is installed, transverse acceleration and yaw gyro sensor, be used for gathering body vibrations, wheel bounce, the signal such as bodywork height and heeling condition, these signals are imported into control unit ECU, ECU sends control command according to incoming signal and the program preset, control servomotor and handle four, front and back to perform cylinder efficient.Realize the liter of bodywork height by the mode increasing and decreasing hydraulic oil or fall, namely automatically adjusting the ground Clearance according to the speed of a motor vehicle and road conditions, thus improving ride comfort and the road-holding property of automobile.
Electromagnetic suspension system (Magnetic Ride Control) utilizes the novel independent suspension system of the one of inductive reaction, it can for surface conditions, react within 1 millisecond of time, suppress vibration, keep vehicle body to stablize, particularly more can show its advantage when the very high prominent chance obstacle again of the speed of a motor vehicle.Faster than traditional suspension 5 times of its speed of response, even on the road surface of jolting most, also can ensure vehicle smooth-ride.Electromagnetic suspension system is made up of vehicle control syetem, wheel displacements sensor, electromagnetic liquid depression bar and straight tube shock absorber.Have a wheel displacements sensor at each wheel and vehicle body junction, sensor is connected with vehicle control syetem, and control system is connected with straight tube shock absorber with electromagnetic liquid depression bar.Straight tube shock absorber is different from traditional hydraulic damper, does not have tiny valve mechanism, is not the object being reached vibration damping by the resistance to flow of liquid.Also have damping liquid in electromagnetic damper, but that is a kind of special liquid (Magneto-rheological Fluid) being called as electromagnetic liquid, is made up of the hydro-carbon synthesized and small abrasive grit.At ordinary times, magnetic metal particle is distributed in liquid desultorily, does not play what effect.If there is magnetic fields, they will be arranged in a fixed structure, and damping liquid will become the state of approximate plastics.The density of damping liquid accurately can control by controlling current flow, and is that in good time continuous print controls.The working process of system is: when Uneven road causes wheel bounce, signal is reached control system rapidly by sensor, control system sends instruction, electric signal is sent to the electronic coil of each shock absorber, the motion of electric current produces magnetic field, and under the influence of a magnetic field, the density of the electromagnetic liquid in shock absorber changes, control vehicle body, reach the object of vibration damping.Complexity is said in change like this, and but can carry out 1000 times in one second, be complete instantaneously.Electromagnetic suspension system can fast and effeciently make up beating of tire, and expands the action radius hung, and reduces noise, improves manipulation accuracy and the travelling comfort of vehicle.Its effect is also so more than, and medical investigator has utilized this technology to produce artificial knee.
