Description

Museu-dong short-range shifter of car

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a mobile near-field moving apparatus for a vehicle capable of moving a short distance without operating an engine of a parked and stopped vehicle.

More specifically, an electric motor driven by a battery is installed in the vehicle body separately from the engine which is the driving source, and the electric motor and the existing power transmission system are connected by belt transmission means so that the engine is operated as in parking and stopping. The present invention relates to a near-distance moving device of a motor vehicle, which is simple to use by operating an electric motor without stopping the engine even in a stopped state, and contributes to fuel saving and prevention of air pollution.

In general, the vehicle is driven by receiving power from the engine installed in the front part, and is divided into a front wheel drive type for driving the front wheel, a rear wheel drive type for driving the rear wheel, and a four wheel drive type for driving both the front and rear wheels.

Among them, the front wheel drive type is a car that transmits the power output from the engine to the front wheel and is driven. Engine power is transmitted in the order of engine, clutch, transaxle, axle, wheel.

Further, as shown in FIG. 1, the rear wheel drive type is a motor vehicle which transmits and outputs the power output from the engine 10 to the rear wheel and drives the engine 10 → clutch 20 → transmission 30 → propulsion shaft 40 →. Power is transmitted in the order of the longitudinal reduction gear and differential gear device (50, 60) → axle shaft (70) → wheel.

The four-wheel drive type is a vehicle in which power output from the engine 10 is transmitted to both the front and rear wheels as shown in FIG. 2, and thus, the engine 10 → clutch 20 → transmission 30 → transmission case. (80) → Front propulsion shaft (100) → Front longitudinal reduction gear and differential gear device (110,120) → Transfer to front wheel to drive front wheel and backward propulsion shaft (100) → Rear longitudinal gear reduction device (130,140) → Rear axle shaft → Rear wheel The rear wheel is driven to drive the vehicle.

However, in the four-wheel drive type, the fuel consumption increases when driving by transmitting power to both the front and rear wheels, and driving the four wheels only when driving on hills or rough roads, and driving only on the rear wheels when driving on flat roads. Drive and drive.

Therefore, most of automobiles adopt rear wheel drive type for driving rear wheel.

On the other hand, regardless of whether the front-wheel drive type, the rear-wheel drive type or the four-wheel drive type is used, the engine is stopped during parking and stopping, and the side brake is locked or released with the transmission gear in the transmission in the neutral position.

In other words, when stopping the car for continuous driving such as a signal stand while driving, only the side brake is locked without stopping the engine, and the side brake is always locked regardless of whether the engine is started on a sloped road.

However, when the vehicle is parked or stopped on a flat surface or a parking lot, the engine is stopped and the side brake is released with the transmission gear in a neutral position.

The reason for releasing the side brake is to make it possible to change the position of the vehicle as well as the other vehicles at the time of stopping and stopping, and to secure the access road of the other vehicle.

Conventionally, when the driver stops the vehicle after completing the parking and stopping of the vehicle as described above, and the driver wants to correct the parking / stopping position of his / her vehicle with the transmission gear in the neutral position, open the vehicle door and start the vehicle again. And then moved forward or backward.

Therefore, such a device needs to open the door of the car again, start the vehicle, and then move the vehicle forward and backward when the vehicle is parked or stopped and the vehicle is slightly moved to correct the position or to secure the entrance of another vehicle. Fuel consumption is excessive, air pollution, and inconvenient disadvantages.

In addition, in a narrow place such as an indoor parking lot, the indoor air is seriously polluted and measures are required, and the driver has a problem such as wasting unnecessary time.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and its technical problem is to provide an apparatus capable of automatically moving a short distance without starting up a parked or stopped vehicle.

In order to achieve the above object, the present invention is to install an electric motor operated by a battery separately from the engine which is the driving source of the automobile, and to connect the electric motor with a belt which is an existing power transmission means and another transmission means.

According to the present invention, when the shift lever of the parked / stopped vehicle is in the neutral position, only the electric motor can be operated without starting the engine to move the vehicle forward or backward within the required range.

Therefore, position correction at the time of stopping and stopping can be performed quickly, unnecessary operation and time are saved, and fuel consumption and air pollution prevention can be contributed.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the exemplary embodiment of the present invention, only the case of the rear wheel drive type has been described. In the case of the front wheel drive type and the four wheel drive type, only the installation position is shifted, so the description thereof is omitted.

Figure 3 is a perspective view of the main portion of the rear wheel drive type coupled device of the present invention, Figure 4 is a side view thereof.

As shown, the power output from the engine 10 is transmitted from the clutch 20 to the transmission 30 to the propulsion shaft 40 to the reduction gear and differential gear device 50 and 60 to the axle shaft 70 to the wheel. In the rear wheel drive type of vehicle that is transmitted to the rear wheel in order,

An electric motor 150 installed on a frame constituting the vehicle body above the propulsion shaft 40 and electrically connected to a battery installed therein, and capable of forward and reverse rotation;

Pulleys 170 and 180 arranged on the motor shaft 151 of the electric motor and the corresponding propulsion shaft 40 and connected to each other by a belt 160;

A switch 190 installed outside the vehicle body to drive an electric motor; It consists of.

The electric motor 150 capable of forward and reverse rotation is firmly attached to the vehicle body above the propulsion shaft 40 and is electrically connected to a battery (not shown) installed in the vehicle.

The two pulleys 170 and 180 are installed on the motor shaft 151 of the electric motor 150 and the propulsion shaft 40 at a corresponding position thereof, and are connected to the belt 160 as a transmission means.

The pulleys 170 and 180 preferably reduce the diameter of the pulley 180 arranged on the propulsion shaft 40 than the pulley 170 arranged on the motor shaft 151 to achieve a deceleration effect.

The switch 190 for controlling the electric motor 150 is installed on the outside of the vehicle body as shown in FIG. 5 to operate outside the vehicle, and the forward switch for forward rotation with the operation switch 191 for turning on the electric motor. 192 and reverse switch 193 for rotating in reverse.

The present invention configured as described above can be effectively used when the transmission gear is placed in a neutral position on a flat or parking lot, and the vehicle is to be moved forward or backward after completing the parking and stopping.

For example, it can be effectively used when changing the position of the vehicle in order to change the parking position or stop position of his vehicle in the state of stopping or stopping the vehicle.

In this case, the driver may slowly move the vehicle forward or backward through the external switch 190 without having to operate the engine again.

That is, when the operation switch 191 of the switch 190 is pressed, the power of the battery is applied to the electric motor to operate. In this state, when the forward switch 192 is pressed, the electric motor 150 rotates forward and the rotational force is two. The vehicle gradually moves forward as it is transmitted to the propulsion shaft 40 through the pulleys 170 and 180 and the belt 160.

On the contrary, when the reverse switch 193 is pressed, the electric motor rotates in reverse, and the rotational force is transmitted to the propulsion shaft 40 through the two pulleys 170 and 180 and the belt 160 so that the vehicle reverses by the reverse operation.

At this time, the pulleys 170 and 180 are slower than the ones installed on the motor shaft, and thus exhibit a deceleration effect, so that the pulleys 170 and 180 may slow down when moving forward and backward.

Therefore, the driver can move his or her car forward or backward as necessary while controlling the electric motor by the above switch operation even when the engine is stopped, thereby preventing unnecessary fuel consumption and air pollution.

The apparatus of the present invention is not limited to the rear wheel drive type, but can be applied to a front wheel drive type or a four wheel drive type car as it is.

In the case of the front-wheel drive type, the electric motor is installed on the vehicle body installed on the upper propulsion shaft, and the pulleys are laid on the motor shaft and the lower propulsion shaft, respectively, and then connected by a belt.

In the case of the four-wheel drive type, the electric motor is installed on the upper body of the rear thrust shaft, and the pulleys are laid on the motor shaft and the rear thrust shaft of the lower portion, and then connected by a belt.

In this way, the power of the electric motor can be transmitted to the driving wheel, and the engine stops and the parking stop is completed while the transmission gear is neutral, and then the driver can move the vehicle at any time without starting the car through the electric motor. It is possible.

As described above, the present invention provides an electric motor operated by a battery separately from an engine which is a driving source of an automobile, and installs a belt transmission means between a motor shaft of the electric motor and a propulsion shaft which is a power transmission means. In the case of a vehicle parked and stopped in a neutral position, the electric motor can be used to move forward or backward as needed without starting the engine.

Therefore, it is not necessary to start the engine when securing the course of parking and stopping and other vehicles, thereby contributing to fuel saving and air pollution prevention.

In addition, the operation is easy and quick to contribute to the improvement of the quality of the car.
