Definitions

  • the present invention relates to a braking mechanism for vehicles, consisting of brake discs consisting of two parts joined by hydraulic shock absorbers or, by other type of joint, thus obtaining that the pads that push them do not press with such force and not even nor the discs are fixed and static.
  • a braking mechanism for vehicles consisting of brake discs consisting of two parts joined by hydraulic shock absorbers or, by other type of joint, thus obtaining that the pads that push them do not press with such force and not even nor the discs are fixed and static.
  • the wheel is prevented from stopping immediately and, therefore, that the driver cannot be done with the direction of the vehicle. They also prevent wear and temperature increase by friction of the pads, since it is no longer braked by pressure but by fluidity.
  • These two brake discs are installed on the front wheels, since they are the ones that drive the vehicle and the objective of this mechanism is none other than that the driver can be done with the steering at all times, even if the braking is very drastic
  • the present invention has its field of application in the automobile industry and, singularly, in the industry of safety mechanisms applied to the brakes.
  • the rapid braking causes the skidding in the curves and the lack of adhesion.
  • ABS brakes completely eliminate the pressure with which, although they solve the problem of the wheel stop, on the other hand, they leave them free and, if the desire is to stop before an obstacle arises, it will not obey the car when pressing the brake pedal.
  • the system proposed by the present invention provides the following advantages to the state of the art:
  • the damping between the two faces of the brake disc causes that the braking is not abrupt and the driver can take control of the vehicle.
  • the wheel is not paralyzed in its turn, but slows down, so that the driver controls the direction of the vehicle and, at the same time, prevents it from colliding with the obstacle that may be in front of it.
  • the present invention is constituted from the pressure exerted on a vehicle by the brake pedal operated by the driver.
  • said pressure is extended to the four wheels, operating a mechanism in the form of two calipers containing two circular pads, which are actuated upon reaching the force extended by the brake fluid.
  • the mechanism ends in two brake discs separated by small hydraulic pistons or other types of cushioning, provided that the disc is divided into two pieces.
  • the purpose of this damping is to prevent the wheel from abruptly immobilizing, preventing the driver from losing control of the vehicle's direction. What does not prevent any mechanism that is incorporated between both discs, is the braking, since the pressure of the brake pads continues to act and the wheel slows down until it stops.
  • the pads are installed on each side of the two brake discs, putting pressure on them. This always causes a movement, both on the discs and on the brake pads. Therefore it is necessary that the pads are not fixed, but accompany the movement of the discs. If the braking force is very sharp, these discs separated by a damping such as pistons or silicone bag prevent a drastic stoppage of the wheel rotation. If the braking is of less force, the movement of immobilization of the turn is the same as the braking without this damping. These two discs, separated as already said by small hydraulic pistons or any other mechanism are attached to the wheels and turn and stop at the same time as these.
  • a piston bases its mechanism on the impossibility of a dense liquid such as oil being diminished by a force exerted on it, so that its inner body is divided into two spaces, one that is filled with liquid and another that is occupied by a piston, leaving two narrow openings. So, when the first space is pressed by a force, it pushes the liquid and it tends to occupy the space where the piston that allows the liquid to enter through its two openings, thus reducing the force of the first thrust and reducing it.
  • a similar mechanism such as a silicone bag.
  • the operation of the device begins when the driver presses the brake pedal.
  • the brake fluid disperses the force by the four wheels and, in addition, multiplies by moving a caliper that brings two pads closer, which imprison the rotation acquired by the brake disc when rotating together with the wheel, but in this case the dampers housed between both discs reduce the force exerted by the pads, causing the braking, in the case of being soft, to be carried out by the wheels in a conventional manner, while if it is abrupt, the force is decreased, the rotation of the wheel not being drastic that can prevent driver maneuverability
  • a different embodiment is constituted by installing said brake disc on the two front wheels, but not on the rear wheels since it is the front wheels that maintain the direction of the vehicle.
  • Another different embodiment is constituted by the fact that the damping of two brake discs is carried out by means of a silicone bag or by any other means appropriate to the circumstances.
  • a preferred embodiment is constituted from the pressure exerted on a vehicle by the brake pedal (7) operated by the driver. Through the brake fluid (8) said pressure is extended to the four wheels (6) by operating a device in the form of two calipers (1) containing two pads (2) in a circular shape that are actuated upon reaching the force extended by the brake fluid (8).
  • the disc it carries has been divided into two (3 and 4) being separated by small hydraulic pistons (5).
  • the pads (2) are installed on each side of the two brake discs (3 and 4) exerting pressure on them. way accompany the movement of the disks (3 and 4). These two discs (3 and 4) are separated by small hydraulic pistons (5).

Abstract

La présente invention concerne un mécanisme de freinage basé sur la pression qu'exerce, dans un véhicule, la pédale de frein actionnée par le conducteur. Par l'intermédiaire du liquide de frein, ladite pression est transmise aux quatre roues, ce qui actionne un dispositif se présentant sous forme de deux pinces contenant deux plaquettes de forme circulaire qui sont actionnées à l'arrivée de la force transmise par le liquide de frein, ledit dispositif se caractérisant en ce qu'au lieu de comporter un seul disque de frein, ce dernier est divisé en deux parties séparées par de petits pistons hydrauliques. Les plaquettes sont installées de chaque côté des deux disques de frein et exercent une pression sur ces derniers. Ces disques sont accouplés aux roues et tournent ou s'arrêtent en même temps que celles-ci.
