The thicknesses of the lines and the sizes of the components shown in the accompanying drawings may be exaggerated for clarity and convenience of explanation.

In addition, the terms described below are defined in consideration of the functions of the present invention, and these may vary depending on the intention of the user, the operator, or the precedent. Therefore, definitions of these terms should be made based on the contents throughout this specification.

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

1 is a configuration diagram of a VCM motor testing apparatus according to the present invention. The VCM motor testing apparatus according to the present invention includes a brake 20 for applying a rotational load to a VCM motor 10, A temperature tester 40 for applying a temperature load to the VCM motor 10, and a control unit 100 for controlling the operation of the vibration tester.

The vibration shaker 30 is installed on the bottom of the test room and a temperature tester 40 is installed on the upper part of the vibration shaker 30. The VCM motor 10 to be tested is placed inside the temperature tester 40 And the brake 20 is connected to the output shaft 11 of the VCM motor 10 via the connecting shaft 50. [ The mounting position of the brake 20 is also fixed.

The vibration shaker 30 is of an electronic type, a water pressure type, and the like, and the electronic vibration shaker is schematically shown in FIG. The electromagnetic vibration shaker 30 is provided with a field coil and an armature (hereinafter referred to as a vibrating portion 32) in the outer casing 31 so that the vibrating portion 32 can oscillate according to the magnetic field forming state of the field coil will be.

A fixing jig 70 is mounted on the upper surface of the vibrating portion 32 of the vibration shaker 30 and the VCM motor 10 is fixed to the fixing jig 70. The fixed jig 70 simulates a mechanical state in which the VCM motor 10 is mounted on the intake manifold, so that a tapped hole corresponding to the tapped hole of the VCM motor 10 is formed and can be fixed with a bolt.

The connection between the VCM motor 10 and the brake 20 is made by the connecting shaft 50 as described above. Both ends of the connecting shaft 50 are connected to the output shaft 11 of the VCM motor 10 and the braking shaft 21 of the brake 20 via couplings 61 and 62, respectively. The couplings 61 and 62 are connected to the output shaft 11 of the VCM motor 10 by couplings 61 and 62 by connecting the connecting parts on both sides in a state in which relative rotation is impossible, The connecting shaft 50 and the braking shaft 21 of the brake 20 are integrally rotated.

The brake 20 may be a powder brake or a hysteresis brake. The brakes 20 are installed outside the temperature tester 40 because the braking force varies depending on the temperature. Therefore, the connection shaft 50 is installed so as to pass through one side wall of the temperature tester 40. A through hole is formed in one side wall of the temperature tester 40 for the connection shaft 50 and a temperature atmosphere formed inside the temperature tester 40 through a gap formed between the connection shaft 50 and the inner circumferential surface of the through hole is connected to the outside A heat insulating material 45 is installed in the gap.

The temperature tester 40 is installed on the upper portion of the vibrating shaker 30 but is connected to only the outer casing 31 of the vibrating pancake 30 without mechanical connection with the vibrating portion 32, The temperature tester 40 does not vibrate because vibration is not transmitted from the temperature sensor 32. Therefore, the heat insulator 45 is made of a material (for example, rubber or sponge) capable of elastically deforming so as to allow the temperature tester 40 to move in accordance with the vibration of the VCM motor 10 and the connection shaft 50 .

The temperature tester 40 is provided with a heater, a cooler and a fan, the heater is an electric resistance heating body, and the cooler is a cooling core in which refrigerant circulates. The fan sucks the outside air and exchanges heat with the heater or the cooler to supply the inside of the temperature tester 40 (precisely, the temperature chamber).

The control unit 100 controls the operation of the brake 20, the vibration shaker 30 and the temperature tester 40.

A torque sensor 80 is installed on the connection shaft 50 to measure a torque formed on the connecting shaft 50 in response to the action of the VCM motor 10 and the brake 20, 100). Therefore, the control unit 100 can control the braking force of the brake 20 according to the torque value applied to the connecting shaft 50, and thus the rotational load of the VCM motor 10 can be accurately controlled as desired.

In addition, the control unit 100 may control the operation of the vibration shaker 30 to variously adjust the direction and magnitude of the vibration. That is, the control unit 100 can operate the vibration shaker 30 to form various vibration load conditions on the VCM motor 10. [ The actual traveling vibration data may be input to the control unit 100 for various road conditions (e.g., a general flat road surface, a Belgian road, and a washboard) in order to realize the same vibration condition as the actual vehicle. That is, the vibration data measured while traveling on various roads may be input to the control unit 100, and the control unit 100 may control the operation of the vibration shaker 30 to implement the vibration state of the desired road surface.

The control unit 100 may control the operation of the heater, the cooler, and the fan of the temperature tester 40 to form various temperature conditions of -40 ° C to 140 ° C in the temperature tester 40.

In addition, the control unit 100 performs the test within the test temperature range set by the tester, for example, when the actual test temperature in the temperature tester 40 falls below the lowest value of the test temperature range arbitrarily set by the tester or The control unit 100 controls to stop the operation of all the test equipments. Such control is carried out in order to prevent unnecessary tests from proceeding and to prevent the test equipment from being prevented from excessive temperature rise and fall because correct test data can not be obtained when the test is not performed within the intended test conditions.

The input unit 110 and the display unit 120 are connected to the control unit 40. Accordingly, the tester can input various operating conditions of the brake 20, the vibration shaker 30, and the temperature tester 40 through the input device 110.

The display device 120 is also provided with test condition data in which the control unit 100 inputs (instructs) the brake 20, the vibration shaker 30 and the temperature tester 40, All data handled in the control unit 100 such as actual data collected by a temperature sensor, a torque sensor 80 installed on the connection shaft 50, and the like can be displayed.

The control unit 100 also functions as a controller of the VCM motor 10. That is, the current position and angular velocity of the output shaft 11 of the VCM motor 10 can be recognized from the sensors provided in the VCM motor 10. Therefore, the control unit 100 controls the operating current of the VCM motor 10 according to the target position, the current position, and the angular velocity of the output shaft 11.

In addition, the control unit 100 may include a data storage device to store the above-mentioned actual traveling vibration data on the road surface and all the data acquired during the test.

On the other hand, a rotation angle restricting mechanism (90) may be provided on the connection shaft (50). 2, the rotation angle restricting mechanism 90 includes a base column 91 fixed in position and a lower stopper (not shown) provided at the upper end of the base column 91 to limit a rotation angle of the connection shaft 50 92 and an upper stopper 93 and a locking projection 51 provided on the connecting shaft 50 and engaged with the lower stopper 92 and the upper stopper 93.

The engaging protrusion 51 is a pin-shaped component having a circular or rectangular cross section and is inserted and fixed in a groove formed in the connecting shaft 50.

A lower stopper 92 is formed at its one end with a lower engaging surface 92a on which the engaging projection 51 is engaged when the connecting shaft 50 is rotated downward. The upper engagement surface 93a on which the engagement projection 51 is engaged is formed.

Flanges 92b and 93b are formed at the other ends of the lower stopper 92 and the upper stopper 93, respectively. The lower stopper 92 and the upper stopper 93 can be engaged by fastening the bolts 94 and the nuts 95 while facing the flanges 92b and 93b.

The rotation angle of the connecting shaft 50 is limited by the angle between the lower engaging surface 92a and the upper engaging surface 93a. By limiting the operating angle of the VCM motor 10 in this manner, 10) Mechanical operating conditions can be implemented.

The lower stopper 92 and the upper stopper 93 having different positions of the lower engaging surface 92a and the upper engaging surface 93a can be used to adjust the operation angle of the VCM motor 10 variously have.

In FIG. 1, the rotation angle restricting mechanism 90 is shown as being installed inside the temperature tester 40, but this is only an embodiment. Since the rotation angle restricting mechanism 90 is not related to the temperature condition, There is no limitation.

Thus, the rotation angle restricting mechanism 90 limits the rotation range of the connection shaft 50 and consequently limits the operating angle of the VCM motor 10. [ Thus, when the VCM motor 10 is installed in the intake manifold, it is possible to simulate the actual operating range of the VCM motor 10 according to the operating range of the VCM valve. In addition, testing can be performed within various operating ranges by changing the limiting angular range.

According to the present invention described above, the same test conditions as the actual vehicle condition can be implemented by the brake 20, the vibration shaker 30, the temperature tester 40, the fixed jig 70, and the turning angle restricting mechanism 90 .

Since the fixing jig 70 is manufactured by simulating the assembled state in which the VCM motor 10 is mounted on the intake manifold, the actual mounting structure of the VCM motor 10 is realized.

The operating angle of the VCM motor 10 is limited by the rotation angle restricting mechanism 90. [ Therefore, when the VCM motor 10 and the VCM valve connected thereto are installed in the intake manifold, a state in which the operating angle of the VCM motor 10 is limited by the VCM valve can be accurately implemented.

The brake 20 can realize the operating resistance acting on the VCM motor 10 by the suction resistance and the frictional resistance acting on the VCM valve in operation of the VCM motor 10. [ The rotational load of the VCM motor 10 can be realized. The rotational load of the VCM motor 10 is monitored in real time in the control unit 100 through the torque sensor 80 provided on the connecting shaft 50. The control unit 100 calculates the rotational speed of the VCM motor 10 The load can be feedback controlled.

The vibration shaker 30 can adjust a vibration direction and a size of the vibration unit 32 to implement a vibration condition transmitted to the VCM motor 10 when the vehicle is actually traveling. In particular, by using the vibration data of the road surface obtained in the actual vehicle traveling vibration test, more accurate vibration of the actual vehicle can be realized.

The temperature tester 40 can realize a state in which the inside of the engine room is heated to a high temperature by the heat dissipation heat of the engine during the running of the vehicle by the heater. In addition, the cooler can also realize low-temperature conditions at the beginning of winter driving.

The control unit 100 controls the operations of the brake 20, the vibration shaker 30 and the temperature tester 40 so that the rotational load, the vibration load, and the temperature load acting on the VCM motor 10 are the same as the actual vehicle State. Also, by controlling the operation of the VCM motor 10 in such a state, it becomes possible to perform the endurance test of the VCM motor 10 under the actual vehicle condition.

In this way, test conditions such as rotation, vibration, and temperature can be implemented in the same way as the actual vehicle traveling state and the VCM motor endurance test can be performed, thereby obtaining more reliable and useful test data.

On the other hand, the test apparatus according to the present invention can not implement only the same test conditions as the actual vehicle driving conditions.

The test unit can set the rotating load condition, the vibration load condition, and the temperature load condition as desired through the input device 110. When the test conditions are inputted, the control unit 100 controls the brake 20, the vibration shaker 30, The operation of the temperature tester 40 is controlled to implement the test conditions input by the tester. Therefore, the durability test of the VCM motor 10 can be performed not only in the actual vehicle traveling condition but also under various various conditions, and can be used for development of the VCM motor 10 in the future by acquiring test data under various conditions.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is understandable. Accordingly, the true scope of the present invention should be determined by the following claims.
