The present invention relates to an engine brake auxiliary braking apparatus for a vehicle using magnetic force, and more particularly, to a braking apparatus for increasing the braking force of a vehicle by assisting the engine brake of the vehicle.

A vehicle represented by a motor vehicle is a means of transportation that adjusts the rotational force of an engine or a motor to a predetermined rotation speed in a gear box and transmits the result to a driving wheel.

Hereinafter, a structure of a general vehicle will be briefly described with reference to FIG. 5.

5 is a projection view showing the structure of a general vehicle.

As shown in FIG. 5, when a fuel is supplied to the engine 12 and burned, the general vehicle 10 converts it into rotational energy, passes through a gearbox, and transmits rotational force to the driving wheels 14. As a result, the vehicle 10 operates.

On the other hand, when the vehicle 10 needs to stop as needed, the brake disc 16 is decelerated or stopped by operating the brake pedal provided in the driver's seat by friction with the drive shaft for rotating the drive wheels 14.

Here, deceleration and braking of the vehicle 10 are largely used in three methods.

The first is a normal foot brake. When the hydraulic pressure is generated by pressing the brake pedal provided in the driver's seat, the foot brake moves the brake disc 16 to the drive shaft according to the hydraulic pressure, and braking is performed by friction between the brake disc 16 and the drive shaft. Such a foot brake is installed for each drive wheel 14 on the basis of an automobile. The foot brake can adjust the speed of the vehicle according to the driver's intention by adjusting the braking force according to the strength of the driver's pressing force of the brake pedal.

The second is a hand brake called the side brake. The hand brake is also provided in the driver's seat, and when the hand brake is pulled, the braking disk is moved to the drive shaft by the brake disc installed on the driving wheel at the rear by a cable connected to the hand brake. Such hand brakes are rarely used during the operation of the vehicle and are used to prevent the movement of the vehicle during parking.

Third is the engine brake. When the engine operates the accelerator (accelerator) pedal provided in the driver's seat, the engine generates a rotational motion in accordance with the amount of fuel flowing into the engine. On the other hand, when the driver releases the accelerator pedal, when the engine rotation speed meshed with the gear is higher than a certain speed, fuel flowing into the engine is blocked, and the engine cannot rotate itself. In this case, the rotational force of the drive wheels is transmitted to the engine through the gear box so that the engine is rotated by the rotational force of the drive wheels. At this time, the engine functions as a load resistance that reduces the rotational force of the driving wheels, thereby reducing the speed of the vehicle.

As described above, the engine brake may be used to increase fuel efficiency by preventing unnecessary fuel inflow when the vehicle speed is reduced, or may be used to prevent vapor lock phenomenon caused by a long foot brake on a long downhill road. do.

On the other hand, the first magnetic material described in the present invention is a braking magnet 116, the mounting plate is a magnet mounting plate 114, the second magnetic material means a component equivalent to the brake steel plate (128).

1 is a side cross-sectional view of an auxiliary braking device according to a first embodiment of the present invention, Figure 2 is a front view of the main portion of the auxiliary braking device according to a first embodiment of the present invention.

As shown, the vehicle engine brake auxiliary braking apparatus 100 using the magnetic force according to the first embodiment 100, unless otherwise described for convenience of description below, the 'engine brake auxiliary braking apparatus for the vehicle using magnetic force' is briefly described. The auxiliary braking device is largely composed of a main body 110, a braking unit 120, and a driving unit 130.

The main body 110 provides a space in which braking is performed by magnetic force.

The main body 110 includes a main cover 112, a magnet mounting plate 114, and a braking magnet 116.

The body cover 112 has a hollow cylindrical shape.

The magnet mounting plate 114 has a circular shape coupled to the inner diameter of the main body cover 112, a plurality of installation grooves for installing the brake magnet 116 is formed along the outer circumference, the rotating shaft 124 penetrates in the center A through groove for forming is formed. Although two magnetic mounting plates 114 are shown in the drawings, the present invention does not need to be particularly limited thereto. In order to provide a large braking force, the number of magnetic mounting plates may be increased, or a small braking force and a small installation space may be used. Note that only one magnet mounting plate may be used in consideration of this.

The braking magnet 116 has two permanent magnets coupled to the mounting groove of the magnet mounting plate 114. It should be noted that the number of the braking magnets 116 can also be appropriately adjusted in consideration of the magnitude of the braking force. In addition, the braking magnet 116 may be used as a permanent magnet, as well as an electromagnet having magnetic properties according to the supply of electricity.

The braking unit 120 generates a braking force by the action of the braking magnet 116 and the braking plate 128 of the main body unit 110. The braking unit 120 includes a braking unit side connection end 122, a rotating shaft 124, an extension leg 126, and a braking iron plate 128.

The braking part connecting end 122 is inserted into an insertion groove formed in the driving part connecting part 134.

The rotating shaft 124 is extended to the braking side connection end 122.

The extension leg 126 extends toward the outer circumference of the rotation shaft 124.

The braking plate 128 is further formed on the extension leg 126 and is positioned to maintain a distance spaced apart from the braking magnet 116.

On the other hand, in this embodiment, although the braking magnet 116 is used as the first magnetic body 116 of the body portion 110, a metal having the same magnetic force with respect to the magnet may be used. In this case, the second magnetic body 128 of the braking unit 120 uses a magnet to induce attraction to the metal.

In addition, a magnet may be used for both the first magnetic body 116 and the second magnetic body 128. In this case, the magnets of the first magnetic body 116 and the second magnetic body 128 may have opposite poles so that mutual attraction occurs. It is installed as possible.

The driving unit 130 receives the rotational force of the engine and is connected to the input drive shaft of the gear box shifted at a predetermined rotational speed to transmit the braking force of the brake unit 120 to the engine. The driving unit 130 includes a driving shaft 132, a driving unit side connecting rod 134, and a clutching pad 136.

The drive shaft 132 is connected to the drive shaft of the vehicle to rotate in conjunction with the operation of the engine. Here, the drive shaft of the vehicle means a drive shaft connected to the output of the gear box connected to the engine.

And the connecting end 122 are coupled by friction.

An operation of the auxiliary braking device according to the first embodiment will be described below.

Prior to the description of this operation example, it is assumed that this auxiliary braking device is installed in an automobile. It is also assumed that when the fifth gear in the vehicle is engaged with the engine, the vehicle has a speed of 80 km / h at 1500 rpm and a speed of 100 km / h at 2200 rpm. It is also assumed that the engine brake by fuel cut is terminated at 800 rpm.

In the first step, the driver operates the accelerator pedal to drive the vehicle at a speed of 100 km / h in five gears. At this time, the rotation speed of the engine is maintained at 2200rpm as assumed. In this state, fuel is continuously supplied to the engine by the operation of the accelerator pedal. In addition, since the accelerator pad is in operation, the clutching pad 136 does not operate, and the driving shaft 132 is rotating, but the rotating shaft 124 of the brake unit 120 does not rotate, so that the rotational force of the engine is not consumed unnecessarily. Do not.

In step two, if the driver wants to slow down, he takes his foot off the accelerator pedal.

In the third step, the accelerator pedal is not operated (the accelerator is turned off), and the fuel supply to the engine is stopped (fuel cut) because the engine rotation speed at that time is 2200 rpm. By the accelerator off state, the clutching pad 136 advances toward the brake side connection end 122. On the other hand, the above-described operation of the clutch pad 136 may be made by stepping on the brake pedal, it may be made by a separate switch as described above.

In the fourth step, the engine is stopped by the fuel cut. At the same time, the driving part connecting rod 134 and the brake part connecting end 122 are frictionally engaged by the clutch pad 136 to rotate together.

In the fifth step, the rotating shaft 124 is rotated by the rotation of the braking part side connection 122, so that a magnetic force is generated between the braking iron plate 128 and the braking magnet 116. The magnetic force generated here cancels the rotational force of the rotation shaft 124.

In the sixth step, the driving speed of the vehicle is reduced by the resistance of the engine itself and the magnetic force between the braking plate 128 and the braking magnet 116 in the auxiliary braking device 100.

In the seventh step, the engine speed decreases below 800 rpm by the action of the engine brake.

In the eighth step, the control unit of the vehicle is to prevent the stop of the function of the various devices of the vehicle caused by the engine stop when the engine number is reduced to less than 800rpm, the idling rotation speed, the drive unit side connecting rod 134 and the braking unit side Sensors that electrically control the frictional engagement of the connecting plate 122 operate to facilitate engine rotation.

Through the above steps, the braking force by the magnetic force is added to the braking force of the engine brake by the conventional engine load, so that the braking speed of the vehicle is increased.
