Description

Apparatus for transmitting auxiliary power of automobile

The present invention relates to an auxiliary power transmission device for a vehicle, and more particularly, by configuring one main power installed in a vehicle to be used as an auxiliary power for driving a separate body unit at the same time as driving power according to driving. The present invention relates to an auxiliary power transmission device for a vehicle, which can be easily applied to a vehicle, and greatly reduces the installation space and cost, thereby improving economic efficiency and structure.

In general, an internal combustion engine of an automobile is used as a driving unit for driving an automobile, and a variety of gasoline engines, diesel engines, and the like are actually widely used.

The internal combustion engine is being moved to the operation of a number of auxiliary units in addition to the driving device of the vehicle, such a kind of auxiliary unit is a winch (reccar) equipped with winches, heavy construction equipment, or a variety of agricultural machinery, leisure cars, such as cleaning trucks, fire trucks It is applied to special vehicles.

In this case, in order to provide sufficient torque used for driving the auxiliary unit, it has been proved to be very advantageous to mount and use an independent auxiliary engine in a vehicle, and the auxiliary engine is installed separately from the main engine of the vehicle. By doing so, it is most commonly applied.

Looking at the vehicle using the structure of the above form as an example, it may be a road cleaning car.

The driving of the vehicle uses a traveling device composed of an engine, a clutch, a transmission, a reduction gear, etc. provided in a commercial vehicle, and the auxiliary unit for driving the cleaning work device is equipped with a separate auxiliary engine and uses the power obtained therefrom. Blowers and hydraulics are used for cleaning.

However, in the work vehicle of the above-described structure, the work is usually performed at a working speed of 5-10 km, but in the case of the manual transmission vehicle, the work efficiency is remarkably increased due to frequent stops and shifts due to the characteristics of the work. Not only is it degraded, but the clutch is badly worn.

In addition, since the auxiliary engine may be a second internal combustion engine or an electric motor, the structure of the system is complicated, and the cost of installation is high, and noise and soot increase as well as fuel consumption are disadvantageous. have.

In addition to these problems, there are various structural problems such as loading efficiency of the work vehicle is reduced due to the installation space and weight due to the fuel tank, radiator and related parts required to drive the two engines.

On the other hand, unlike the above-described structure as a power for supporting the auxiliary unit has been proposed to distribute the power of the main engine of the vehicle to the auxiliary unit to be used as an auxiliary power for work in addition to the driving power.

In this structure, the power required to drive the vehicle is driven by transmitting the power generated from the engine to the wheels of the vehicle through the transmission, and the auxiliary power required for the operation is carried out by using the auxiliary power transmission device. Work is performed by connecting to work equipment.

However, in general, a vehicle can be driven at a high speed by the basic performance, but when a separate auxiliary unit is installed in the vehicle, a separate oscillation means (PTO) provided by the vehicle after stopping the vehicle to drive the auxiliary unit is provided. Not only had to drive the auxiliary unit using Power Take off, but also could not realize the high power auxiliary power source at the same time as driving.

In addition, in order to implement this, it is required to use an expensive automatic transmission that is specially manufactured to take out auxiliary power at the same time of driving.

Despite the above conditions, the power of the auxiliary unit is proved to be more advantageous to use the power of the vehicle as the auxiliary power without using a dedicated automatic transmission or an auxiliary engine.

Looking at this technique as an example, it may be a patent application No. 99-42010.

This device should use the high output PTO, not the general auxiliary PTO attached to the side of the engine transmission, and drive one hydraulic pump to drive the hydraulic motor of the auxiliary drive system. It is configured to drive a special device (negative pressure generating device) by using a pulley connected to it.

As a problem of this, a separate high power transmission PTO should be installed, and a special external device that requires an auxiliary power source using a hydraulic pump and a pulley by using a separate external power take-off shaft is required for cost and space limitations. There is a problem.

In addition, a considerable amount of effort is required to apply it to a special vehicle. In particular, an auxiliary driving device for ultra low speed driving uses a separate single-plate clutch to transmit power to the drive shaft reducer. In order to use the single-plate clutch is essential because it is expensive and complicated structure.

Moreover, the single plate clutch has a disadvantage in that it needs to be replaced due to wear after a certain time.

The present invention is proposed to improve the conventional problems as described above, the object of the auxiliary power transmission device of the vehicle to drive at least one auxiliary unit by taking out the main power as auxiliary power while driving the car In providing.

In particular, special transmission vehicles and agricultural machines that can carry out various tasks at the same time with one power according to the main power of the automobile, as well as various transmission vehicles and clutches for special vehicles that are manufactured for special tasks other than general use chassis. It can be easily realized without using.

This object is achieved by providing an improved power transmission device, i.e., the present invention transmits auxiliary power to take out auxiliary power along with auxiliary driving on a propulsion shaft that transmits the power generated from the engine of a vehicle to the rear wheel. By providing means, it is characterized in that a part of the main power source can be utilized in the work device at the time of work without impairing the high speed driving performance of the automobile.
