The present invention relates to a power transmission system, and more particularly to a beltless drive power transmission system for automobiles.

Conventionally, the power transmission method in a vehicle is simply driven by using a rubber belt and a pulley, and a method of transmitting power by friction force between the belt and the pulley by using a plurality of belts on one main side pulley and using the force. It was.

That is, as in the conventional manner of FIG. 1, when the engine 1 is driven, the driving pulley 2 rotates, and this rotational force drives the generator driven pulley 4 via the V belt 3, thereby generating the generator 5. Was the way to rotate.

Such a conventional method requires regular belt replacement and inspection, noise generation and power loss due to sagging of the belt, difficulty in determining the life and condition of the belt, and normal running difficult due to unexpected belt breakage, If power transmission or power transmission distance of the part which is not horizontal transmission is far, power transmission is difficult, and related driving parts have to be installed in parallel with the drive shaft pulley, which limits the power transmission and does not have long belt life compared to other parts. A problem occurred.

The present invention is to solve the various problems in the conventional rubber belt method used for driving the accessory in the vehicle, the present invention is equipped with a spiral bevel gear on the crankshaft of the engine and coupled via a drive pinion, one-way clutch A beltless drive system for automobiles that is connected to a flexible bowl joint cable with a connection tube that incorporates a flexible bowl joint with a spline and coupling balls, and then drives the generator through a generator drive pinion, a spiral bevel gear, and a generator shaft. To provide.

The present invention is a vehicle-less belt for driving a generator, a water pump, a power steering pump, etc., which are automobile accessories, using a flexible ball joint cable instead of a belt as a medium for transmitting power between vehicle engine room parts. Provides a drive power transmission system.

The flexible ball joint cable according to the present invention is connected to the coupling spline having the coupling groove and the guide groove as the coupling ball and inserted into the connection tube or the flexible hose to smoothly transmit power in a curved surface. will be.

The present invention uses a spiral bevel gear and pinion in the drive system to compact the drive system, and the power is transmitted in one direction only by using a one-way clutch in the flexible bowl joint cable. To provide a beltless drive power transmission system for automobiles that enables power transmission in curved surfaces.

It is a maintenance-free power transmission system that guarantees power transmission and has a semi-permanent life, and does not require special inspection or adjustment, using a flexible bow joint cable according to the present invention.

The present invention will be described in detail with reference to the drawings showing preferred embodiments.

In FIG. 2, the spiral bevel gear 12 is mounted on the crankshaft 11 of the engine 1, and the coupling spline 22 and the coupling bowl 25 are connected to each other through the driving pinion 13 and the one-way clutch 14. It is connected to the flexible bowl joint cable (20) having the connection tube (26) having the flexible bowl joint (21) having a built-in drive pinion (13 ') and spiral bevel gear (12') again The generator shaft 15 is configured to drive the generator 5.

Here, the coupling spline 22 is a spline shaft having a coupling groove 23 and a guide groove 24, which is one kind of special key and may have various shapes.

Referring to the operating state of the present invention configured as described above; When the engine 1 is driven, the crankshaft 11 rotates, and the driving spiral bevel gear 12 connected thereto rotates, and when the drive pinion 13 rotates, the power is transmitted to the one-way clutch 14 to connect the tube. Through the 26, the flexible ball joint 21 starts the rotational movement to drive the generator drive pinion 13 ', and this force drives the spiral bevel gear 12' to rotate the generator shaft 15 connected thereto. The generator 5 starts normal operation.

However, when the engine 1 rapidly decelerates and then decelerates, the rotational speed of the generator 5 is increased by the engine 1 and then the generator 5 and the engine 1 when the engine 1 decelerates rapidly. Unbalance of rotation is made between the rotational speed at this time may be higher than the speed of the engine (1) because the generator (5) has received an exaggerated state. Accordingly, when power is transmitted in reverse (from generator to engine), the one-way clutch 14 operates to prevent power from being transmitted in reverse, so power transmission is always made in one direction (engine to generator).

The present invention can completely replace the rubber belt used in the automobile, which makes the device compact, its lifespan is semi-permanent, no separate inspection and adjustment is required, power loss can be minimized, The present invention is an advanced useful invention that provides a beltless driving method and apparatus for automobiles that are capable of transmitting power smoothly and delivering relatively large torque as well as smooth power transmission over a relatively long distance.
