Abstract

A vehicle braking system has two plates forming a disk 1 which accommodates a copper coil 10 wound on triangular shape supporters 8 so that the coil can convert current flow to a magnetic field attracting or repulsing magnetized pads 6 to lock and unlock the brake. The current fed to the coil via brushes 11 and rails 7 from a variable resistor (2, figs 1 and 2). The current going into the variable resistor is supplied from a power generator (4, figs 1 and 3) when a driver applies a pedal (5, fig 1). The pads may have steel backs, and be made of a substance which is a mixture of carbon and a substance which can be magnetized.

Description

-1- ELECTRO MAGNETIC FIELD BRAKING SYSTEM

This invention relates to an electro magnetic field braking system.

Magnet is well known body having the property of attracting iron as well as steel and producing a magnetic field external to itself. There is a special magnet type known as

magnetic flux made of lines characterized by electromotive forces developed by magnetic means used to present magnetic induction. The magnetic flux itself made of a coil and can be accommodated between two plates of metal or can be wound around a rod will have the property to attract and repulse external bodies. This can replace the conventional braking system known as fluid or hydraulic braking system.

Hydraulic braking systems, however, besides of their advantages, relatively expensive due to the excessive parts used.

According to the present invention there is provided a conventional double sided disk brake comprising an internal coil wound around triangular supports separating both inner and outer plates of the disk, two brushes conducting current fixed behind the disk, a power generator situated under the bonnet, and a variable resistor operated by the function of the braking pedal linking the generator to the brushes to increase decrease or cut the current flow.

A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which: Figure 1 shows in one dimension, the main components of the brake:

-2 Figure 2 shows the box containing the variable resistor; Figure 3 shows the electric generator; Figure 4 shows in perspective the copper magnetic flux coil wound on the triangular support within the double sided disk brake, and the pads from both sides of the disk; Figure 5 shows the intermediary brushes touching the disk; and Figure 6 shows the triangular arrowed supports linking both plates of the disk and accommodating the copper coil around them.

Referring to the drawing the design comprises a wheel disk 1, a variable resistor connector 2, a wire for the current flow 3, a power generator 4, and a brake pedal 5.

In order to reduce, increase or cut the current flow a variable resistor 2 is used and located between the generator and the disk as illustrated in Fig 1 When the current flows to the coil 9 via the contact brushes 11 touching the border rails 7 of the disk as illustrated in Fig 4 and Fig 5 respectively, it is then converted to a magnetic flux which magnetizes the plates which in turn attract inward and repulse outward the magnetized and demagnetized brake pads 6 as illustrated in Fig 4 by using the opposite direction arrows.

As the wheel is rotating it is decelerated when the driver applies on the pedal 5 as illustrated in Fig 1 and due to the power of induction of the magnetic field created by the

coil 10 wound between the plates 1 around the triangular supports 8 of the disk as

-3- illustrated In Fig 4, the magnetized brake pads 6 are then equally attracted from both sides of the disk causing the car to stop.

To release or harden the brakes gradually, the variable resistor adjusts the amount of current flowing to the coil through the brushes. To completely release them, the variable resistor cuts out the current flow.
