REGENRATIVE SUSPENSION SYSTEM

A Vehicle as a whole energy system losses most of its energy while running due to load and other consequences, so as an argument the vehicle own recuperate some of its energy on its own which is lost in the surrounding.

So here pronounced a system which can regenerate energy from the vertical wheel movement which is lost as kinetic energy in the suspension system by assisting a “linear alternator” with it.  Thus the system produces electrical energy from the kinetic energy of the vehicle, so the system is mainly suitable for electric and hybrid vehicles.

As this system will drive a greater amount of electricity and much more efficient than other regenerative system known, thus it would be a promising technology of the future vehicle industry. 

This “regenerating suspension system” is actually an electricity generating suspension system which generates the electricity from the kinetic energy of the wheel suspension system, solves or reduces the problem of fully electric and hybrid cars. In particular, a substantial increase in several hundred kilometers is raised in accordance with the existing battery storage capacity, without any additional electricity cost and with absolutely “Zero CO₂ emission” this system increases the range of the vehicle at least by 50% in the relation to the battery storage capacity and the resulting range.

Working

(The generation process)

So, in the regenerating suspension system the electricity is produced by the “linear generator” which is mechanically coupled with the suspension system of the vehicle. So basically this generator is producing electricity through kinetic energy from the vertical wheel suspension movement and excess body acceleration.

To achieve optimum vehicle fuel efficiency with auxiliary power generating devices which recuperate energy losses from parasitic displacement motion from road bumps and vibrations, it would be advantageous to develop innovative regenerative devices which exhibit high energy conversion efficiency and power generation capacity and supplement vehicle power requirements for vehicles traveling at normal speeds on typical road surfaces. Due to the potential power generation capabilities and energy conversion efficiencies of linear electromagnetic generator devices when compared to conventional mechanical linear motion conversion devices, regenerative electromagnetic shock absorbers whose electrical output characteristics are matched to vehicle power, damping and electrical load requirements for typical driving conditions are prime candidates for improving vehicle fuel efficiency.

 

Energy generation from the vertical body movement

As falsely assumed by some industry specialist that the system is not the recuperation of the drive power of the vehicle motor, the excess kinetic energy of the vertical body movement which is absorbed by the steel spring or the other conventional suspension system and converted into electricity.

(The amount of energy yield can be much higher if the conventional suspension system is completely omitted and replaced by a novel suspension system)  

Outcome:

With a higher total sprung weight, the energy yield is likewise much higher. The body weight thus has a direct effect on the amount of electricity produced by the "electricity-generating suspension system".

In order to justify the additional cost and weight penalties for equipping vehicles with these auxiliary power generation devices, regenerative devices which are capable of generating peak power ranging between 2 to 20 kW, average power ranging from 1 to 6 kW, with a power generation capacity ranging between 10 to 100 watts per kg, with typical energy conversion efficiencies of at least 50% would be most advantageous. Additionally, a regenerative vehicle shock absorber which provides not only efficient energy recovery but also road shock and vibration damping is particularly desirable for satisfying the competing requirements of increased fuel efficiency and enhanced passenger comfort and safety.

Other advantages of the system

·         Combining a suspension capable of adjusting its power consumption over time using energy optimizing algorithms and/or energy neutral algorithms may enhance the efficiency of the suspension. In addition, it may allow an active suspension to be integrated into a vehicle without compromising the current capacity of the alternator. For example, the suspension may adjust to reduce its instantaneous energy consumed in order to provide enough vehicle energy for other subsystems such as an anti-lock braking system (ABS brakes), electric power steering, dynamic stability control, and engine control units (ECUs).

·         A suspension system as described herein may be associated with an active chassis power management system adapted to control power throttling of the suspension system. More specifically, a controller responsible for commanding the active suspension responds to energy needs of other devices on the vehicle such as active roll stabilization, electric power steering, and other appropriate devices.

·         In one example of a suspension system and controlled to provide on-demand energy, energy consumption might be required throughout a wheel event, such as when a vehicle encounters a speed bump. Energy may be required to lift the wheel as it goes over a speed bump (that is, reduce distance between the wheel and vehicle) and then push the wheel down as it comes off of the speed bump to keep the vehicle more level throughout. However, rebound action, such as the wheel returning to the road surface as it comes down off of the speed bump may, fall into the positive energy flow cycle by harnessing the potential energy in the spring, using extension damping to regenerate energy.
