Description

A power maintenance apparatus for reducing of fuel installed on the drive shaft of the car}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel saving power maintenance device installed on a propulsion shaft of an automobile power transmission device. Particularly, it is possible to maintain a constant speed that is already accelerated without a continuous output of an engine when driving a vehicle at high speed for a long time, thereby significantly reducing fuel consumption. Of course, it is a fuel-saving power maintenance device installed on the propulsion shaft of the automobile power transmission device suitable for preventing environmental pollution.

Generally, a power transmission device for a vehicle is a device for transmitting power output from an automobile engine to a driving wheel, and in the case of a front engine rear wheel drive car, a clutch, a transmission (T / M), a propulsion shaft, and It is composed of rear axle, etc. and transmits the power output from the engine to the driving wheel.

Therefore, the power train has a great influence on the fuel consumption as well as the actual power output of the vehicle.

Thus, Figure 1 is a block diagram showing a conventional vehicle power transmission device.

As shown in the drawing, the power transmission device shifts the clutch bite to suit the driving condition (starting, climbing, flat road driving, etc.) and the clutch 103 to control the power as necessary, such as when starting or shifting, and moving forward and A transmission 105 for reversing, a propulsion shaft (Propeller Shaft or Drive Shaft) 107 for transmitting the output of the transmission to the differential device 105 in the rear wheel drive vehicle, and a rotation speed of the transmission are finally reduced to left and right driving wheels. It is configured to include a differential device 105 for transmitting power at a suitable rotational speed to the 111, to transmit the power output from the engine 101 to the drive wheel 111. Here, the differential device 105 is composed of a differential shaft 106 coupled to the propulsion shaft 107 and a rear axle 109 for driving the driving wheel 111 by receiving the rotational force of the differential shaft 106.

However, in the conventional power transmission device, when the driver slows down the accelerator during the high speed driving of the vehicle, the output of the engine is drastically decelerated, and the influence of the power is reflected on the driving wheel through the propulsion shaft and the speed of the vehicle is sharply dropped.

That is, since the output of the engine is transmitted to the driving wheel of the vehicle as it is, it is required to maintain the high speed rotation of the engine as it is at high speed. The rotation of is thus also reduced.

In particular, when the driver slows down the accelerator, the engine rotation speed decreases to an idle rotation speed (approximately 800 rpm), and thus the rotation of the driving wheels receiving power from the engine also occurs. This phenomenon is referred to as an engine brake. For this reason, in order to maintain a constant speed, which has already been accelerated during high-speed driving of a car for a long time, the engine must be continuously output, which causes a problem of waste of fuel.

Accordingly, the present invention has been proposed to solve the above-mentioned conventional problems, and an object of the present invention is to maintain a driving force of the propulsion shaft by rotational inertia without the continuous output of the engine during a high speed driving of a vehicle for a long time and accelerated to a constant speed. It is to provide a fuel-saving power maintenance device that is installed on the propulsion shaft of the automobile power transmission device to enable fuel saving by maintaining the.

In addition, the present invention includes a drive clutch pipe 4 is installed in the housing 10, the drive clutch pipe 4 is coupled to the propulsion shaft 107 at one end. Here, the connecting means 22 is used for coupling the drive clutch tube 4 and the propulsion shaft 107. The connecting means 22 is fitted to be fixed to the end of the propulsion shaft 107 and is configured to bolt to the drive clutch tube (4). As such, the drive clutch tube 4 is coupled to the propulsion shaft 107 so that the driving clutch pipe 4 is rotated together by the rotation of the propulsion shaft 107.

In addition, a plurality of jaws 41 are formed in the inner diameter of the drive clutch tube 4. The jaw 41 has a portion of the side of the power transmission piece 44 when the power transmission piece 44 to be described later is advanced in the direction of the drive clutch pipe 4 as indicated by the dotted line in FIG. Hooked on the side of the jaw 41 formed in (4) to allow the rotational force of the drive clutch tube 4 can be transmitted through the power transmission piece (44).

In addition, a driven clutch pipe 2 is installed inside the drive clutch pipe 4. The inner diameter of the driven clutch pipe 2 is equipped with a differential shaft 106 installed in the differential device 105. To this end, axial irregularities are formed on the outer circumferential surface of the differential shaft 106, and axial irregularities 55 are formed in the inner diameter of the driven clutch pipe 2 so that the differential shaft 106 is driven clutch pipe 2. Fit into the inner diameter of the to be combined.

Therefore, when the driven clutch tube 2 rotates, the rotational force is transmitted to the differential shaft 106. Here the differential shaft 106 is coupled with the rear axle 109. In addition, a plurality of grooves 43 are formed in the outer diameter of the driven clutch pipe 2.

Meanwhile, a plurality of power transmission pieces 44 are installed in the plurality of grooves 43 formed in the outer diameter of the driven clutch pipe 2, and the power transmission pieces 44 are driven by clutches shown in dotted lines in FIG. The side part is caught by the side of the jaw 41 when advancing in the direction of the pipe 4 and is not caught by the side of the jaw 41 when retiring toward the driven clutch tube 2 as indicated by the solid line in FIG.

As a result, the power transmission piece 44 transmits the rotational force of the drive clutch tube 4 to the driven clutch tube 2 at the time of advancement, and transmits the rotational force of the drive clutch tube 4 to the driven clutch tube 2 upon exit. You will not.

On the other hand, a bearing (5) is provided between the drive clutch pipe (4) and the driven clutch pipe (2). The bearing 5 supports the drive clutch pipe 4 and the driven clutch pipe 2 so that the rotational force of the drive clutch pipe 4 cannot be directly transmitted to the driven clutch pipe 2.

Furthermore, the present invention comprises a power transmission piece operating means for advancing or withdrawing the power transmission piece 44.

The power transmission piece operating means includes a plurality of connecting pins 31 and compression springs 33 and the power transmission piece 44 which are elements which exert a force in the direction in which the power transmission piece 44 advances. It consists of magnetic force generating means for applying force.

Here, the connecting pin 31 is coupled to the power transmission piece 44 and is installed in the plurality of holes 30 formed in the bottom surface of the groove 43 of the driven clutch pipe 2 to be retractable. The compression springs 33 are respectively installed in the plurality of holes 30 and apply a first force to the connecting pin 31 in the direction in which the power transmission piece 44 is evicted. As a result, the power transmission piece 44 is constantly receiving a force in the direction of retirement.

On the other hand, the magnetic force generating means is installed in the housing 10 and is configured to generate a magnetic force upon application of electricity to apply a second force greater than the first force in the direction in which the power transmission piece 44 advances.

That is, since the power transmission piece 44 is made of a metal material, a second force is generated to move toward the magnetic force generating means by the magnetic force of the magnetic force generating means. The magnetic force generating means is composed of a coil 8 for generating a magnetic force, the second force is greater than the first force, such as the strength of electricity applied to the coil 8 or the number of turns of the coil 8 is installed. . 3 and 4, the coil 8 is provided inside along the circumference of the housing 10. As shown in FIG.

On the other hand, the magnetic force generating means is preferably such that when the driver applies a force to the accelerator (accelerate) the electricity is applied. That is, when the driver accelerates by stepping on the accelerator with the foot, the sensor is installed in the vicinity of the accelerator to sense the control so that electricity is applied to the magnetic force generating means.

Then, the power transmission piece 44 is advanced by the magnetic force generated as the magnetic force generating means so that the power of the propulsion shaft 107 is transmitted from the drive clutch pipe 4 to the driven clutch pipe 2. Then the power of the propulsion shaft 107 is transmitted to the differential shaft 106 mounted on the driven clutch pipe (2).

On the other hand, when the driver releases the force applied to the accelerator, the electricity applied to the magnetic force generating means is short-circuited so that the power transmission piece 44 is evicted by the elastic force of the compression spring 33, and as a result, the power of the propulsion shaft 107 It is not transmitted from the drive clutch pipe 4 to the driven clutch pipe 2.

In addition, the power transmission piece operating means injects air to act on the rear surface of the power transmission piece 44 through the through-hole 53 formed in the housing 10 so that the power transmission piece 44 is advanced. It may be configured to include an air pressure injection means not shown to apply a force in the direction. That is, in order to advance the power transmission piece 44 more easily, the force by air pressure is added to the back surface of the power transmission piece 44.

At this time, in the present invention, the first sealing ring 13 is provided between the housing 10 and the drive clutch tube 4 to prevent the air injected into the rear surface of the power transmission piece 44 in the housing 10 from counting. The second sealing ring 11 is further installed between the driving clutch pipe 4 and the driven clutch pipe 2.

Here, in the case of the air pressure injection means, it is preferable to operate when the driver applies the force to the accelerator as in the magnetic force generating means.

On the other hand, the present invention can be configured to further include an air drive (9) having a rotary shaft (7) geared with the driven clutch pipe (2). That is, a gear is formed on a predetermined portion of the outer circumferential surface of the driven clutch plate 2, and a rotary shaft gear is coupled to the gear formed on the outer circumferential surface of the driven clutch plate 2 on the rotary shaft 7 of the air drive 9. 19) is fitted.

Thus, even when the driven clutch pipe 2 is not receiving the rotational force by the drive clutch tube 4, the additional rotational force is applied to the driven clutch tube 2 by the air drive 9 to provide the rotational force to the differential shaft 106. Will give That is, since a large vehicle typically includes an air storage tank for storing air used in a brake device, the air drive 9 is rotated by supplying air, thereby turning the driven clutch pipe 2 to turn the fuel of the engine. The differential shaft 106 can be driven without consuming. Such an air drive 9 is preferably made to operate when the power transmission piece 44 has evicted.

The operation of the fuel saving power holding device installed on the propulsion shaft 107 of the vehicle power transmission device according to the present invention configured as described above will be described in detail as follows.

First, an operation of transmitting the power of the propulsion shaft 107 to the differential shaft 106 to accelerate the vehicle is described. When the driver of the vehicle steps on the accelerator, a sensor (not shown) installed near the accelerator detects the magnetic force generating means. Control so that electricity is applied.

Then, a magnetic force is generated in the magnetic force generating means, and the power transmission piece 44 is pulled in the direction of advancing in the direction of the drive clutch tube 4 as indicated by the dotted line in FIG. 4 by the generated magnetic force. Some of the sides of the) is caught by the side of the jaw 41 formed in the drive clutch tube (4).

After that, the rotational force of the driving clutch tube 4 which is combined with the propulsion shaft 107 to rotate is transmitted to the driven clutch tube 2 through the power transmission piece 44. Rotation of the driven clutch tube 2 will eventually rotate the differential shaft 106 mounted thereon, whereby the power of the propulsion shaft 107 is transmitted to the differential shaft 106.

On the other hand, when the driver releases the force applied to the accelerator, a sensor (not shown) installed near the accelerator detects this and shorts the electricity applied to the magnetic force generating means. Then, the power transmission piece 44 is moved away in the direction of the driven clutch tube 2 as indicated by the solid line in FIG. 4 by the elastic force of the compression spring 33 acting on the connecting pin 31, so that the jaw 41 is removed. The driven clutch pipe 2 does not receive a rotational force from the drive clutch pipe 4.

Therefore, the propulsion shaft 107 and the differential shaft 106 are separated from each other so that the power of the propulsion shaft 107 is not transmitted to the differential shaft 106 and the differential shaft 106 is idle. As a result, the vehicle is continuously advanced by the inertial force of the vehicle, not by the power of the propulsion shaft 107.

On the other hand, when the air pressure injection means is further installed as the power transmission piece operation means, the air pressure injection means injects air through the through-hole 53 formed in the housing 10, the injected air is the power transmission piece ( Let air pressure act on the back of 44). That is, the air injected into the housing 10 moves in the direction of the arrow shown in FIG. 3 so that air pressure acts on the rear surface of the power transmission piece 44.

The injected air exerts a force in the direction in which the power transmission piece 44 is advanced, and the power transmission piece 44 is more easily advanced in the direction of the drive clutch tube 4. Here, in the case of the air pressure injection means, it is preferable to operate when the driver applies the force to the accelerator as in the magnetic force generating means.

On the other hand, when the present invention further includes an air drive 9 having a rotary shaft 7 geared with the driven clutch pipe 2, the air drive 9 is rotated by receiving air stored in the vehicle The clutch tube 2 is rotated to apply rotational force to the differential shaft 106. That is, when the power transmission piece 44 is evicted and the vehicle continues to move forward by inertia, by applying rotational force to the driven clutch pipe 2 by using the additional air stored in the vehicle without consuming fuel used in the engine. It will be able to give assistance to the car. To this end, the driver may release the force applied to the accelerator so that the air drive 9 is operated after the power transmission piece 44 is evicted.

This allows the vehicle to continue to be driven by the inertia force and the air drive 9 even if the driver does not step on the accelerator.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.
