Definitions

  • This invention relates to brake systems and applies in all fields of the automotive industry.
  • this invention has the advantage of warning the driver of a vehicle in the case of the bearing overheating due to the lack of lubricant and where locking of the shoe pad occurs without the knowledge of the driver.
  • the warning is the result of the high temperature which is generated by the friction between the shoe pad and the wheel, disc, or wheel drum or within the wheel bearing assembly.
  • This invention is designed so as to monitor the temperatures as close to the brake drums and disc brakes as possible and gives the driver a warning signal of the location of the heating wheel if a temperature anomaly occurs in one or more wheels compared to the temperature of the other wheels of the vehicle.
  • An electronic comparator differentiates between the normal heat generated over a long distance of heavy braking such as on a hilly or mountainous descent or with a general rise of ambient temperature such as on hot days during summer driving.
  • Figure 1 is a cross section view of a conventional wheel and brake assembly of a motor vehicle where the brake is of the drum type.
  • Figure 2 is a schematic view of a brake assembly of the disc brake type.
  • Figure 3 represents the logic flow of the system ⁇ and
  • Figure •% illustrates a schematic perspective view of the panel display gauge for the driver.
  • the brake assemblies shown in Figures 1 and 2 are usually very well housed to prevent water from entering into the assembly.
  • Figure 1 shows the wheel assembly of a conventional brake drum type where 1 is the wheel backing plate, 2 is the brake shoe, 3 is the brake drum, 5 is the main axle, while 6 and 7 are the wheel rim and tyre respectively.
  • the temperature sensor is drilled into the shown position in the backing plate as only an illustration, as such a sensor could also be mounted on the brake shoe, wheel cylinder; however in the opinion of the inventor, the backing plate is one of the most stable parts of the wheel assembly due to its non-mobility, and its close distance to the wheel drum, which makes it respond much faster to any temperature rise.
  • the temperature sensor is of any type such as thermocouple, switching sensor which is triggered at a set temperature, diode, or electronic type; and they are all fitted securely to said backing plate or any other position by means of nuts, washers and bolts.
  • Figure 2 shows the disc brake assembly 1, braking pads 2 and wheel braking disc 3; and Figure 2 illustrates the most appropriate position to install the said heat sensor 4 in the case of a disc brake assembly, where it could be mounted on one of the two lock clips 5 which exist with every disc brake assembly system; or said sensor 4 could be simply mounted in a hole drilled in the assembly 1 and as close to the disc as possible.
  • the electric switch sensors which will close or open (depending on the type) at a pre-set temperature limit, a direct wiring to the electronic circuit is connected.
  • a"higher set temperature sensor on the front wheel,for example 200°C triggering point, compared to the back wheels due to the fact that when braking, the heavier load is usually on the front wheels compared to the back wheels; this will consequently cause higher temperatures to be generated in the front wheels than those in the back wheels.
  • Tempjerature sensors in the back wheels could be set, for example to be triggered at 150 C. These pre-set temperature sensors are fitted with different ranges to suit the type of vehicle and the size of the wheel assembly.
  • Temperature sensors of any type may be synchronised with the electronics so as to give two levels of warnings; say one for overheating but not reaching any dangerous level, and the other for if and when the overheating continues to increase giving a very high and dangerous level of heat. Said two levels of warning gives the driver an indication of the level of danger and if that level is not very high he does not have to stop immediately , which may cause traffic inconvenience. Furthermore, said warnings will give him the chance to drive to the nearest repair station or town. Furthermore, temperature sensors could also be fitted on parts of the motor vehicle which are likely to be damaged due to lack of lubricant such as the gearbox, and differential box(es).
  • thermocouples & diodes would require more electronic decoders to convert the signals from volts or amperes into a usable temperature which in turn is pre-set electronically for an upper temperature limit.
  • the information is relayed into another electronic comparator which in simple terms looks at all wheels at the same time and immediately gives a warning to the driver after locating the position of the wheel when said wheel shows an anomalously high temperature compared to other wheels.
  • Figure 4 shows a schematic front view of a standard size gauge 1 similar to those on the panel such as the speedometer.
  • Figure 4 illustrates a large type of motor vehicle consisting of truck with its schematic presentation in the form of wheels 4, 2 and trailer with its schematic presentation 3.
  • Button 6 is for testing and when pressed lights all warning lights 5; and if the trailer is not attached to the truck, no light appears in the trailer warning lights. Furthermore if the situation arises that the wires are disconnected or there is a faulty circuit, said situation is indicated when switch 6 is pressed, and for safety a warning light and sound also appear,in the case of a faulty circuit during driving,on the light next to WIRES DISCONNECTED.
  • gauge 1, Figure 4 Lights 5, 7 and 8 automatically appear on gauge 1, Figure 4, to correspond to the same overheating wheel, gearbox or differential so as to save the driver the time of checking all wheels for the one(s) which is/are overheating.
  • Gauge 1, Figure 4 will vary according
  • gauge • to the type of vehicle and it is suggested in the case of railway trains that said gauge be of the digital reading type giving a number which corresponds to the sequence number of the railway wagon together with a general warning light and warning sound.
  • Lights 5, 7 and 8 could be made of two different bulbs or one diode which has the capacity to give two colours, say orange and red so as to indicate to the driver the level of heating.
  • the device provides a very unique warning display system for the driver so as to reduce the time taken in finding the faulty wheel.

Abstract

En plaçant un détecteur thermique (4) aussi près que possible de la surface de freinage (3) on obtient un avertissement anticipité en cas de surchauffe provoquée par des problèmes de palier de roulement ou de blocage de freins (2), attirant l'attention du conducteur avant qu'une panne ait lieu. Des détecteurs thermiques (4) sont connectés à un dispositif de contrôle électronique pour repérer une ou plusieurs roues ayant une température anormalement élevée par rapport aux autres roues, de manière à empêcher l'émission d'un avertissement lorsque toutes les roues surchauffent à cause d'une descente à forte inclinaison et à la suite d'une utilisation prolongée des freins. Le dispositif de contrôle électronique envoie une tonalité et un signal d'avertissement au conducteur sur un affichage du tableau de bord, indiquant au conducteur la position de l'élément qui surchauffe.
