Description

Hybrid kit {Hybrid Kit}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hybrid kit, and more particularly, to a hybrid kit capable of implementing a hybrid system as a simple structure,

In recent years, hybrid vehicles have been developed and sold for the purpose of improving environmental pollution and fuel efficiency.

Such a hybrid vehicle is provided with a motor driven by a battery in addition to an engine serving as an internal combustion engine so that the internal combustion engine and the motor are used together, or only one of them is selectively used.

1, a hybrid vehicle is provided to be transmitted to a drive wheel 50 having the same rotational force by the engine 10 or the motor 30, as shown in Fig. Therefore, a complex power transmission device 20 must be provided in order to transmit the rotational force of the engine 10 and the motor 30 to the same drive wheel 50. [

Since the power transmission device 20 is very expensive and needs to be reflected from the design to the hybrid system, there is a problem that it is impossible to apply the hybrid system through modification to the vehicle that has already been produced.

Korean Patent Publication No. 10-1998-0077935

SUMMARY OF THE INVENTION It is an object of the present invention to provide a hybrid kit capable of applying a hybrid system through a simple modification to an automobile already produced.

The problems of the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.

According to an aspect of the present invention, there is provided a vehicular drive system for a vehicle, which is installed on a vehicle coaxially with a follower wheel that receives no driving force from an internal combustion engine and is integrally rotated with the follower wheel, A first sprocket having gear teeth on its outer periphery, a motor provided on the vehicle, a second sprocket rotated by the motor, and a second sprocket arranged to span the first sprocket and the second sprocket, A hybrid kit comprising a power transmission chain for transmitting rotational force is provided.

The first sprocket includes a drum portion coupled to the follower wheel and having a circular space formed therein so as to have a brake shoe therein, a sprocket portion extending outwardly from the periphery of the drum portion, can do.

The first sprocket may include a mounting portion coupled with the follower, a disk extending outwardly from the periphery of the mounting portion, a disk formed to be in contact with the brake pad, and a sprocket portion having gear teeth formed around the outer periphery of the disk.

The sprocket portion may be located closer to the vehicle center side than the rim of the follower wheel.

The motor may be installed in a vehicle body of a vehicle.

The hybrid kit of the present invention has the following effects.

First, there is an advantage that a hybrid system can be applied to a live vehicle by a simple device configuration alone.

Secondly, since heavy parts such as motors are provided on the vehicle body rather than on the wheel, the increase of the unsprung mass is minimized, so that the deterioration of the vehicle performance can be minimized.

Thirdly, since the driving force by the hybrid kit is transmitted to the follower wheels, the vehicle to which the hybrid kit is applied has the effect of adding the function of the four-wheel drive.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.

The foregoing summary, as well as the detailed description of the preferred embodiments of the present application set forth below, may be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, there are shown preferred embodiments in the figures. It should be understood, however, that this application is not limited to the precise arrangements and instrumentalities shown.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In describing the present embodiment, the same designations and the same reference numerals are used for the same components, and further description thereof will be omitted.

The hybrid kit 100 according to the present embodiment may include a first sprocket 110, a motor 120, a second sprocket 130, and a power transmission chain 140 as shown in FIG.

The first sprocket 110 is installed coaxially with a follower wheel 60 that is not receiving the driving force from the internal combustion engine 10 and is integrally rotated with the follower wheel 60, And gear teeth may be formed around the outer periphery.

The motor 120 is installed in the vehicle, and may be provided to be driven by receiving power from a battery 42 or a generator (not shown) installed in the vehicle. In addition, the motor 120 may be supported to be coupled to the vehicle body 5 and not to be supported by wheels or knuckles (not shown) of the vehicle. That is, the motor 120 may be coupled to an upper portion of a suspension device (not shown) of the vehicle to form a part of a current virtual mass.

The second sprocket 130 is rotated by the motor 120, and gear teeth may be formed around the second sprocket 130.

The power transmission chain 140 is disposed to extend over the first sprocket 110 and the second sprocket 130 and meshes with the gear teeth of the first sprocket 110 and the second sprocket 130, 1 sprocket 110 and the second sprocket 130 to transmit the mutual rotational force between the first sprocket 110 and the second sprocket 130. At this time, the power transmission chain 140 is not necessarily limited to a chain, and may include a belt.

Accordingly, when the motor 120 is rotated, a rotational force is transmitted to the follower wheel 60 through the first sprocket 110 through the power transmission chain 140, so that the drive wheel (not shown) driven by the internal combustion engine 10 50) or can drive the vehicle alone.

Meanwhile, the hybrid kit 100 according to the present embodiment will be described as an all-wheel drive vehicle having one pair of front wheels and one pair of rear wheels.

A driving force of an engine such as the internal combustion engine 10 or the like is transmitted to the front wheel 50 through the power transmitting device 22 so that the front wheel 50 can be steered, And the rear wheel 60 can be steered only at a very small angle even if it is not steered or steered without receiving the driving force of the internal combustion engine 10 as a follower wheel.

Therefore, the hybrid kit 100 of the present embodiment can be applied to the rear wheel 60, which is a follower wheel. That is, the first sprocket 110 may be rotated to rotate integrally with the rear wheel 60.

3, the wheel 62 is made of a material having rigidity such as metal, and the tire 66 is made of a rubber material And is provided around the outer rim of the wheel 62.

In addition, the wheel 62 is coupled to a hub (not shown), the center of which is a rotation axis, and a brake can be coupled to the inside of the wheel 62. Alternatively, a hub (not shown) may be coupled to the brake, and the wheel 62 may be engaged with the brake so that the brake itself forms part of the rotating shaft.

The brake is a component for decelerating the vehicle by friction with a brake pad (not shown) or a brake shoe (not shown) to convert the rotational force of the wheel into a frictional force and consuming it. The brake may be a drum type or a disk type.

The first sprocket 110 of the present embodiment may be integrated with the brake. However, the present invention is not limited thereto, and it is also possible that the first sprocket 110 is provided separately from the brakes.

In this embodiment, the first sprocket 110 is integrally formed with a drum type brake.

The first sprocket 110 may include a drum portion 112 and a sprocket portion 114, as shown in FIGS.

The drum portion 112 may be formed on the inner side of the wheel 62 to rotate with the wheel 62 to form a circular space so that a brake shoe (not shown) .

Such a brake shoe (not shown) may be provided so as to be rubbed against the inner circumferential surface of the drum portion 112 by braking by the driver's operation.

The sprocket portion 114 may extend outwardly from the periphery of the drum portion 112 and may have gear teeth formed around the outer periphery thereof.

At this time, the sprocket portion 114 may be positioned away from the rim 64 closer to the center of the vehicle than the rim 64 of the wheel 62, as shown in FIG. The size of the sprocket portion 114 is not limited to the inner circumferential size of the rim 64 so that the size of the sprocket portion 114 can be freely designed and the power transmission chain 140 can be designed on the rim 64 Interference can be avoided.

In addition, when the first sprocket 110 is applied to the rear wheel 60, the rear wheel 60 is generally not steered or steered only in a very small amount, thereby avoiding the disengagement of the power transmission chain 140.

The front wheel 50 driven by the power of the internal combustion engine 10 can be driven by the motor 120 to the rear wheels 60 so that the function of the four wheel drive can be exhibited. , The driving stability and the running performance on the rough road can be further improved.

On the other hand, in general, in the case of the suspension load of the vehicle, that is, in the case of the unsprung mass, the reduction of 1 kg is similar to the reduction of the present virtual weight (the weight of the suspension at the upper side) of 15 kg The hybrid kit 100 of the present embodiment is configured such that relatively heavy components such as the motor 120 are coupled to the vehicle body 5 to constitute a current virtual mass and only relatively light components such as the sprocket portion 114 are suspended It is not added to the mass, so it may not deteriorate the motion characteristics such as the road surface following force of the vehicle. In addition, since the first sprocket 110 performs the function of the brake necessary for the vehicle at the same time, it is possible to minimize the increase of the weight of the vehicle and the number of parts.

A hybrid kit according to a second embodiment of the present invention will now be described. The hybrid kit according to the present embodiment is an example in which the hybrid kit is integrally provided with a disk type brake. The first kit differs from the first embodiment in that the first sprocket 210 is different from the first embodiment. In the explanation of the embodiment, the first sprocket 210 will be mainly described, and the same parts as those in the above-described embodiment will not be described.

The first sprocket 210 may include a mounting portion 212, a disc 214, and a sprocket portion 216, as shown in FIG.

The mounting portion 212 may be a component that is coupled to the center of rotation of the follower wheel 60.

The disc 214 may extend radially outward from the periphery of the mounting portion 212 and may be formed to be in contact with a brake pad (not shown) to exert frictional force.

The brake pads (not shown) may be provided to frictionally bend against the outer surface of the disc 214 by operation of the driver.

The sprocket portion 216 may be formed with gear teeth around the outer circumference of the disc 214.

In addition, the sprocket portion 216 may be positioned away from the rim so as to be closer to the vehicle center side than the rim 64 of the wheel 62, similar to the first embodiment described above.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
