Definitions

  • the present invention relates to a shock damping member whereby viscosity and thermal conductivity characteristics are enhanced by metal oxides such as copper oxide, iron oxide, silicon oxide or aluminium oxide included in a damping fluid.
  • Dampers shock absorbers
  • dampers are one of the main organs of the moving part (chassis) included in vehicles and they provide the comfort and safety for the drive and ensure the connection of the vehicle with the road. Dampers function as a hydraulic piston mechanism which is responsible for continuously maintaining the balance of the vehicle and providing the comfort necessary for the persons inside the vehicle to travel for a long time and they put up a resistance that is opposite to the direction of movement of the vehicle and parallel to the speed of the vehicle.
  • the damping fluid which is an oil-like fluid included in the damper, absorbs the energy generated by shock and vibration by converting it into heat.
  • An objective of the present invention is to realize a shock damping member which enables to realize performance enhancement by increasing the viscosity and thermal conductivity at high temperatures by using hybrid nanoparticles in damping elements.
  • Another objective of the present invention is to realize a shock damping member which enables to obtain high damping force and high cooling performance by using metal oxides such as copper oxide, iron oxide, silicon oxide or aluminium oxide as nanoparticle.
  • Another objective of the present invention is to realize a shock damping member which enables to enhance damping performance at high temperatures by adding damping fluid, that is pure oil, and metal oxide at a rate varying between 0.3-0.5%.
  • Figure l is a section view of the inventive shock damping member.
  • the inventive shock damping member (1) whereby performance enhancement is realized by increasing the viscosity and thermal conductivity at high temperatures by using hybrid nanoparticles in damping fluid comprises:
  • the inner tube (2) is a pressure tube wherein the damping fluid, that is pure oil, is included and the damping process occurs. Pure oil is included in the inner tube (2) as the damping fluid.
  • the inner tube (2) comprises hybrid nanoparticles wherein at least two metal oxides exist together with the damping fluid.
  • the said hybrid nanoparticles in the inner tube (2) are created by joining at least two of copper oxide, iron oxide, silicon oxide, titanium oxide or aluminium oxide together. Nanoparticles with a hybrid structure in the ratio varying between 0.3-0.5% according to the damping fluid are included in the inner tube (2). High cooling performance and damping force are achieved compared to conventional dampers, by using metal oxide nanoparticles together with pure oil. On the other hand, sizes of the damping member (1) are reduced compared to conventional applications by using hybrid nanoparticles.
  • the outer tube (3) contains the damping fluid, that will dampen the motion of the piston rod (4), and the inner tube (2) together during the damping process. Oil flow occurs based on the upward and downward motion of the piston rod (4) between the outer tube (3) and the inner tube (2). Thereby, the damping process can occur upon the volume of the pure oil -that is the damping fluid inside the inner tube (2) and the outer tube (3) - and the piston rod (4) changes continuously based on the vehicle movement.
  • the piston rod (4) included in the inventive shock damping member (1) is a moving component that carries out the damping process based on the road conditions.
  • the piston rod (4) carries out the damping process by moving inside an inner tube (2) which is filled with pure oil wherein metal oxide is added.
  • the repulsion spring (5) creates an additional reaction force for the upward motion of the piston rod (4) inside the inner tube (2) in addition to the damping fluid.
  • the repulsion spring (5) is mounted with two spring guides (6) fixed on the piston rod (4), without contacting the piston rod (4). Thereby, contact of the piston rod (4) - which is metal- and the repulsion spring (5) -which is metal- with each other is avoided.
  • the spring guide (6) is made of a plastic material.
  • the inventive damping member (1) is a damper. Inside the damping fluid included in the damping member (1), which is a damper, a viscosity increase of approximately 30% is observed in the damping elements (1) by means of the nanoparticle structure obtained within the pure oil by using at least two metal oxides exist together inside the damping fluid and an increase in cooling performance from 90 °C to 110 °C occurs in the cooling performance. This increase is between 90- 100°C maximum in the long term and it is between 110-120°C maximum in the short term.
