Abstract

Brakes rear wheels of vehicles with low pressure in the tires, characterized in that it is constituted by a mechanism, in which the mushrooms (1) are located in the transverse center of the rim (2) and are equipped with springs (3) positioned between the heads of the mushrooms (4) and the cylindrical pieces (5), they engage with articulated bars (6) joined to systems converters of the vertical horizontal movement of the mushroom (1) and a surrounding ring (7), inside the rim, which in turn contains another ring (8) of material suitable for braking and a stop (25), which, also performs the function of guiding the rings (7 and 8) in their movement horizontal. These rings (7 and 8) are fastened by a kind of "L" landscape (9) that is built into the rim and the cylindrical part (5). On the other hand, there is the braking disc (10) which runs in the housing on the enclosure (11) of the rotation shaft or bearing (12), by means of square projections (13) that fit over the slots of the disc (14) and his incarcerator (15). On the other side of the disc (10) is adhered to the moving part of the hydraulic system (16), which in turn, at the other end (17) is grasped by a spring (18), which, is subject to the immobile part of the hydraulic system (19) and accompanied by the brake fluid (26).

Description

"FRENOS RUEDAS TRASERAS DE VEHíCULOS CON BAJADA DE PRESiÓN EN lOS NEUMÁTICOS" "BRAKES REAR WHEELS OF VEHICLES WITH LOWER PRESSURE IN THE TIRES"

Object of the Invention

la presente invención, se expresa en el enunciado de esta memoria descriptiva, se refiere a la reducción del espacio recorrido por un vehículo ante la solicitud de detención o disminución de la velocidad del vehículo para lo cual, está provisto de un dispositivo, regulable, del volumen máximo de una cámara de neumático, que actúa cuando el conductor del vehículo acciona el pedal del freno. The present invention, expressed in the statement of this specification, refers to the reduction of the space traveled by a vehicle in response to the request to stop or decrease the speed of the vehicle for which, it is provided with a device, adjustable, of the maximum volume of a tire chamber, which acts when the driver of the vehicle operates the brake pedal.

En la posición de reposo (sin accionar el pedal del freno) con este dispositivos se dan las siguientes características: el volumen de la cámara es mínimo, la presión del neumático es máxima, con lo que, altura del neumático es la máxima. Cuando se acciona el pedal del freno, este dispositivo regula el volumen de ocupado por la cámara y como consecuencia se dan las siguientes características: el volumen de la cámara se incrementa gradualmente según el movimiento del pedal de freno, con el incremento del volumen de la cámara, se registra una bajada de presión en los neumáticos, por lo que aumenta huella del neumático y disminuye la altura del neumático. Con lo que, aumenta la superficie de contacto con el pavimento y una bajada del tren trasero, ayudando de esta manera al frenado del vehículo. In the rest position (without pressing the brake pedal) with these devices the following characteristics are given: the volume of the chamber is minimal, the tire pressure is maximum, so that the tire height is the maximum. When the brake pedal is operated, this device regulates the volume occupied by the camera and as a consequence the following characteristics occur: the volume of the camera gradually increases according to the movement of the brake pedal, with the increase in the volume of the chamber, a pressure drop in the tires is recorded, thus increasing the tire's footprint and decreasing the height of the tire. Thus, the surface of contact with the pavement and a lowering of the rear train are increased, thus helping the braking of the vehicle.

Background of the invention

Es conocido por todos en general el problema que se nos presenta al tener que disminuir la velocidad o incluso detener un vehículo en un espacio reducido. Por ejemplo, en los casos de detención de vehículos circulando a gran velocidad, se puede observar, claramente, que las ruedas traseras del vehículo no desarrollan todo el potencial de frenado que sería conveniente. Es más, tienden a sobrecargar el tren delantero, ya que se genera una fuerza en el centro de gravedad, que tiende a voltear el vehículo (sobrecargando el tren delantero y elevando el tren trasero). It is known by everyone in general the problem that arises when having to slow down or even stop a vehicle in a small space. For example, in cases of stopping vehicles traveling at high speed, it can be clearly seen that the rear wheels of the vehicle do not develop all the braking potential that would be convenient. Moreover, they tend to overload the front train, since a force is generated in the center of gravity, which tends to turn the vehicle (overloading the front train and raising the rear train).

Description of the invention

En líneas generales los "frenos ruedas traseras de vehículos con bajada de presión en los neumáticos", objeto de la invención, está formado por un conjunto de cilindros huecos con cabeza circular y redondeada, que se distribuyen por el centro transversal de la llanta de rueda . Estas piezas, de forma similar a una seta, se posicionan sobresaliendo de la llanta y presionando una cámara de la rueda, In general, the "rear wheel brakes of vehicles with pressure drop in the tires", object of the invention, is formed by a set of hollow cylinders with a circular and rounded head, which are distributed along the transverse center of the wheel rim . These pieces, similar to a mushroom, are positioned protruding from the rim and pressing a wheel chamber,

en posición de reposo. Cuando se acciona el freno, se pone en marcha un sistema hidráulico que permite desplazar, horizontalmente, un disco que se pone en contacto con un aro de material adecuado para el frenado y a la vez transmite un movimiento horizontal que se transforma en bajada de la seta. Dotando de esta manera de menor presión en los neumáticos e incrementando la huella de este. Al dejar de accionar el freno los muelles de las setas y los del disco vuelven a su posición de reposo, incrementándose otra vez la presión en los neumáticos. in rest position. When the brake is applied, a hydraulic system is started that allows to move, horizontally, a disc that comes into contact with a ring of suitable material for braking and at the same time transmits a horizontal movement that transforms into lowering of the mushroom . Giving this way less pressure on the tires and increasing its footprint. When the brake is stopped, the springs of the mushrooms and those of the disc return to their resting position, again increasing the pressure on the tires.
