Description

[0001] The present invention relates to an electric generating cornering-

The present invention relates to an electric generating cornering responsive damper, and more particularly, to an electric generating cornering responsive damper which can improve the stability and riding comfort of a passenger by correcting posture of the vehicle body when the posture of the vehicle body is disturbed by the running of the vehicle, The present invention relates to an electric generating cornering sensitive damper capable of producing electric energy by using load.

Generally, a suspension system of a vehicle connects a wheel and a vehicle body to prevent vibration or shock from being transmitted from the road surface to the vehicle body during traveling, thereby preventing damage to the vehicle body and cargo, A spring for relieving the impact from the road surface, a damper for controlling the free vibration of the spring to improve the ride comfort, and a stabilizer for preventing rolling of the automobile.

In addition, the suspension of such a vehicle has an important role of transmitting the driving force generated from the driving wheels and the braking force of each wheel at the same time to the vehicle body, enduring the centrifugal force at the time of turning, and maintaining each wheel in the correct position with respect to the vehicle body .

A suspension of a conventional vehicle includes: a spring having a predetermined elastic modulus calculated according to the weight and shape of the vehicle body; A damper including a cylinder and a piston is provided in the middle, and the upper and lower ends of the spring are fixed to form a strut connecting the vehicle body and the wheel.

In the suspension system of the conventional vehicle constructed as described above, the optimum elastic modulus required for the suspension device is calculated in consideration of the weight and shape of the vehicle body, and then a spring indicating the calculated elastic modulus is manufactured to connect the vehicle body and the wheel The damper absorbs the shock transmitted from the wheel to the vehicle body. At the same time, the damper damps the vibration of the spring, thereby alleviating the shock transmitted from the road surface while driving the vehicle, thereby improving the ride comfort of the passenger .

However, in the conventional suspension system of a vehicle as described above, shocks of a proper size transmitted to a vehicle body by a combination of a spring and a damper can be effectively absorbed. However, when a relatively small high- The vibration is transmitted to the vehicle body through the spring and the damper. Therefore, the ride feeling of the passenger is significantly reduced.

In addition, when the vehicle turns on a curve, the vehicle body is moved to one side due to inertia, so that the passenger is also pushed to one side. However, the conventional suspension device of the above-described type has no function to prevent the inclination of the vehicle body, Can feel uneasiness, and there is a problem that stability and ride comfort are remarkably deteriorated.
