Abstract
The invention relates to an alternative emergency hydraulic brake system for semi-trailers or trailers, which is independent of the original system. The system of the invention supports the original system in the event of a reduction in the braking power of the original system or it replaces same and stops the trailer by itself in the event of a full system failure. For this purpose, the system of the invention brings the tyres on the rear axles of the trailer into contact with one another by means of a hydraulic piston which moves a sliding carriage, to which the first rear axle of the unit is coupled, towards the next axle until the treads of the tyres rub against one another and, since they are moving in opposing directions at the point of contact, a braking action is generated that can be adjusted as required using controls inside the cab.

SISTEMA DE FRENO HIDRAULICO, DE RESPALDO POR EMERGENCIA HYDRAULIC BRAKE SYSTEM, EMERGENCY SUPPORT
Y ALTERNATIVO, APLICABLE A CUALQUIER TIPO DE CAMIÓN AND ALTERNATIVE, APPLICABLE TO ANY TYPE OF TRUCK
SEMI-REMOLQUE O REMOLQUE La presente patente de invención se refiere a un sistema de freno hidráulico, de respaldo por emergencia y alternativo, aplicable a cualquier equipo de camión semi- remolque o remolque en el mercado; es independiente en todas sus partes del sistema de freno de origen de dichos equipos y requiere de mantención mínima. En caso que falle el freno principal de origen, ese sistema puede comptementarlo si la falla fuera parcial, o bien sustituirlo totalmente si ésta fuese total, pues no solo es capaz de frenar por si solo al equipo, sino que también permite manejarlo, utilizándolo cuidadosamente, hasta el punto más cercano habilitado para reparar la falla del freno de origen. SEMI-TRAILER OR TRAILER This invention patent refers to a hydraulic brake system, emergency backup and alternative, applicable to any truck semi-trailer or trailer equipment on the market; It is independent in all parts of the braking system of origin of said equipment and requires minimum maintenance. In the event that the main brake of origin fails, this system can comptement it if the failure is partial, or replace it totally if it were total, because not only is it capable of stopping the equipment by itself, but it also allows to handle it, using it carefully , to the nearest point enabled to repair the brake failure of origin.
El sistema se basa en el empuje de un pistón hidráulico aplicado a un carro con correderas, el que soporta a las vigas largueras dobte "T" del remolque, deslizándolo por las alas inferiores de éstas; carro que es a su vez sustentado, vía los resortes amortiguadores del remolque, por el primer eje de ruedas trasero del equipo, desplazando a éste hacia el eje siguiente por las vigas doble "T", hasta que los neumáticos en las ruedas de ese par de ejes entren contacto entre sí. The system is based on the thrust of a hydraulic piston applied to a trolley with slides, which supports the longitudinal beams "T" of the trailer, sliding it through the lower wings of these; carriage that is in turn supported, via the shock absorbing springs of the trailer, by the first rear wheel axle of the equipment, moving it to the next axle by the double "T" beams, until the tires on the wheels of that pair of axes enter contact with each other.
Al establecerse dicho contacto se produce un efecto de frenado, por el movimiento en sentido opuesto d las superficjes efe ro¾ad¾ de los i f uffiáti$¾% en una fricción aplicable a pedido, y variable en fuerza a voluntad, por medio del mando eléctrico, o manual, instalado en la cabina del camión tractor. When this contact is established, a braking effect is produced, by the movement in the opposite direction of the effe roved surfaces of the if uffiáti $ ¾% in a friction applicable on request, and variable in force at will, by means of the electric command, or manual, installed in the cab of the tractor truck.
En el estudio técnico se consideró que aquellos frenos de emergencia existentes, que fueran dependientes de algún elemento del freno principal de origen, no son fiables, ya que las balatas/pastillas de freno del sistema de origen, al ser activadas por pistones de aire/aceite a muy alta presión, pueden sobrecalentarse por contacto prolongado cóñ los tám¾óres/digcós dé fréñó y événtualméñté vitrificarse, perdiendo de parcial a totalmente su capacidad de frenado. El anegamiento de éstos tiene un efecto similar. Una falla del compresor de aire del camión, o ruptura en su línea de suministro anulará igualmente la acción del sistema de emergencia que dependa del freno de origen.
La patente KR 20010049563 es de un sistema de diseño simple, tal como la del sistema hidráulico objeto de ésta descripción, pero difiere de éste en que requiere gran cantidad de aire a presión, suministrado por el compresor de aire del camión tractor, por lo cual no es independiente de éste, y cuyos elementos pueden fallar como indicado en el párrafo anterior. In the technical study it was considered that existing emergency brakes, which were dependent on some element of the main brake of origin, are not reliable, since the brake pads / brake pads of the origin system, when activated by air pistons / oil at very high pressure, can overheat by prolonged contact with the tám¾óres / digcós dé fréñó and événtualméñté to vitrify, losing from partial to totally its braking capacity. The waterlogging of these has a similar effect. A failure of the truck's air compressor, or break in its supply line will also cancel the action of the emergency system that depends on the brake of origin. Patent KR 20010049563 is of a simple design system, such as the one of the hydraulic system object of this description, but differs from this one in that it requires a large amount of air under pressure, supplied by the air compressor of the tractor truck, for which it is not independent of it, and whose elements may fail as indicated in the previous paragraph.
La patente de freno auxiliar ES 2276572, independiente e innovadora en teoría, es de difícil implementación y de efectividad práctica, pues requiere de una superficie plana para implantar una pantalla, adherida al techo del camión tractor, y por lo tanto no es aplicable a ramplas o carros de arrastre. The auxiliary brake patent ES 2276572, independent and innovative in theory, is difficult to implement and practical, since it requires a flat surface to install a screen, attached to the roof of the tractor truck, and therefore is not applicable to ramps or drag cars.
Otro freno de emergencia en el mercado, independiente del de origen, es el de la patente US 51201 14, que comprende un aparato antideslizante con unidades electrónicas de control, lo que lo hace muy oneroso en costo de base, y en su mantención, siendo además frágil, pues sus componentes electrónicos están sometidos al rigor del transporte terrestre. Another emergency brake in the market, independent of the one of origin, is the one of the patent US 51201 14, which comprises an anti-slip device with electronic control units, which makes it very costly in base cost, and in its maintenance, being also fragile, as its electronic components are subject to the rigor of land transport.
