Abstract

PURPOSE: A motor for a vehicle is provided to remove a crank gear module by directly the rotation of a crank pulley and performing a start function. CONSTITUTION: In a motor for a vehicle, a pinion gear for rotating the crank shaft is installed at one end of the driving shaft to move along an axial direction, and a cooling fan(4) is integrated with the other end of the driving shaft to be rotated. A pulley(5) with a gear engaging with the pinion gear is mounted at one end of the crank shaft. The pinion gear is installed to move along a driving shaft by a lever(7) which rotates according to the operation of a magnet switch.

Description

Motor for vehicle

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motor for a vehicle, and more particularly to a motor for a vehicle capable of simultaneously performing a function of a cooling fan motor and a start motor with one motor.

In a conventional vehicle, a motor is installed to perform various functions. As shown in FIG. 1, a start motor that performs a starting function of a vehicle is a flywheel ring gear at the tip of a crankshaft 1 driven by an engine. (2) is integrally rotated, the flywheel ring gear (2) is installed to selectively engage the pinion gear (3), the pinion gear (3) in the axial direction to the drive shaft of the start motor (4) It is installed to be movable back and forth along the.

In addition, a magnet switch 5 is installed at the start motor 4 to move the pinion gear 3 back and forth in the axial direction, and one end of the lever 6 is connected to one end of the plunger of the magnet switch 5. The other end of the lever 6 is connected to the pinion gear 3 so that the lever rotates clockwise or counterclockwise according to the operation of the magnet switch 5 to move the pinion gear back and forth in the axial direction. Let's go.

When the vehicle starts, the start motor 4 operates to rotate the flywheel ring gear via the pinion gear to force the engine to be initially driven.

Meanwhile, the cooling fan motor 7 used in the vehicle is installed to rotate the cooling fan as shown in FIG. 2, and adjusts the cooling water temperature to an appropriate temperature while repeatedly operating or not operating according to the cooling water temperature of the engine. It will function.

However, as a plurality of motors performing various functions as described above are used in a vehicle, there are disadvantages in terms of utilization efficiency of the motor, that is, the start motor is not used at all after the vehicle is started. It was necessary to use them properly to perform other functions simultaneously.

Accordingly, the present invention has been made in view of the above circumstances, and reduces the number of motors used in the vehicle to reduce the weight and cost of the vehicle by simultaneously performing the function of the start motor and the cooling fan motor of the vehicle as a single motor. It is an object of the present invention to provide a motor for a vehicle that can be planned.

The present invention for achieving the above object, the pinion gear for rotating the crankshaft at one end of the drive shaft is installed to be movable along the axial direction, the other end of the drive shaft is installed so that the cooling fan is integrally rotated.

Preferably, one end of the crankshaft is equipped with a pulley having a gear meshing with the pinion gear.

According to the motor for a vehicle according to the present invention, as the function of the start motor and the cooling fan motor are performed by one motor, the number of motors can be reduced, thereby reducing the weight and cost of the vehicle, as well as a narrow engine room. The layout of the motor is also improved, and the frequency of motor failures is reduced, which improves the maintenance and quality of the vehicle.The start motor is installed in the cooling fan motor position instead of the cylinder block of the engine. Since the location of the engine does not need to be changed to dualize the engine, investment cost is reduced, and as the start function is performed by directly rotating the crank pulley, the removal of the crank gear module can reduce the number of parts and weight of the vehicle, etc. There is.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in detail with reference to the accompanying drawings.

3 shows a mounting position of the motor according to the present invention in a perspective view, i.e., the motor 1 according to the present invention is fixed to the cooling fan grill 3 in front of the engine 2, so that the motor ( 1) directly rotates the cooling fan to perform the cooling function and to perform the initial starting function of the engine at the same time.

4 is a cross-sectional view taken along the line AA of FIG. 3, wherein the motor 1 is coupled with a cooling fan to rotate the cooling fan 4 and directly connects the crankshaft pulley 5 of the engine 2. It is arrange | positioned adjacent to the front-end | tip of the crankshaft pulley 5 so that it may rotate.

5, a pulley 5 is integrally mounted at the tip of the crankshaft so as to rotate the crankshaft by receiving the rotational force of the motor 1, and a pinion gear provided in the motor on the outer circumferential surface of the pulley 5; The gear 5a is formed so that it may engage with.

6 shows the function of the motor 1 according to the present invention. The motor 1 has a magnet switch 6 and an operation of the magnet switch 6 so as to perform a conventional start motor function. The lever 7 is rotated in accordance with each.

One end of the drive shaft 1a of the motor 1 is mounted with a pinion gear 8 to selectively engage the crankshaft pulley 5, and the cooling fan 4 is provided at the other end of the drive shaft 1a. It is installed to rotate integrally.

In addition, an engine control unit (ECU) is connected to the motor 1 to control the driving of the motor 1.

Therefore, at initial start-up of the vehicle, the magnet switch 6 is operated to rotate the lever 7 so that the pinion gear 8 meshes with the crankshaft pulley 5 along the axial direction. (1) is activated to forcibly rotate the crankshaft, so that the vehicle is initially started.

After the initial start, the lever is rotated back to its original position by the operation of the magnet switch, and the pinion gear moves along the axial direction to be separated from the crankshaft pulley, thereby performing the function of the start motor.

Thereafter, the engine control unit (ECU) senses the coolant temperature of the engine to control the operation and non-operation of the motor 1 to adjust the coolant temperature of the engine, thereby performing the function of the cooling fan motor.
