Description

Steering device installed in armored motorcar on the sea}

The present invention relates to a steering device for an amphibious armored vehicle, and more particularly, to an armored vehicle steering apparatus at sea configured to accurately steer an armored vehicle while the armored vehicle is operating at sea.

The steering wheel is provided in the driver's seat of the armored vehicle to control the direction of the armored vehicle. The steering wheel is manipulated by the driver to allow the armored vehicle to move in the desired direction. The direction change of the armored vehicle as described above can be changed by varying the rotational direction or rotational speed of the endless tracks on both sides of the land, and can be changed by controlling the turning basket at sea.

However, in the conventional steering apparatus as described above, the comparison amplifier 22 has a limitation that the value compared as the analog comparison amplifier is not constant. In addition, in order to drive the turning basket (12, 14), the hydraulic pump must be in the operating state, so that the engine of the armored vehicle is operated, it is possible to check and confirm the function. In addition, since the rotation speed and the rotation angle of the turning baskets 12 and 14 are controlled by a hydraulic actuator operated by an analog comparator, there is a problem that the rotation amount and rotation speed are not constant according to the pressure difference of the hydraulic device.

The present invention has been made to solve the above problems, by constantly comparing the rotation angle of the steering wheel and the turning basket to ensure the correct angle of rotation of the turning basket corresponding to the steering wheel steering, the steering by the turning basket It is an object to provide an armored vehicle steering device at sea, which is always accurate and reliable, and uses a DC motor to rotate the turning basket, so that the device is simple and easy to maintain.

2 is a view schematically illustrating a configuration of an armored vehicle steering apparatus at sea according to an embodiment of the present invention.

Referring to the drawings, the armored vehicle steering apparatus according to the present embodiment is installed on a steering wheel 10 operated by a driver in the driver's seat of the armored car, and the handle shaft 52 of the steering wheel 10. And the first encoder 50 for generating a digital signal by the shaft rotation of the handle shaft 52, and the basket rotation shaft 54 of the turning baskets 12 and 14, and the digital rotation by the rotation of the basket rotation shaft 54. A second encoder (56, 57) for generating a signal, and the second encoder (56, 57) and a direct-current motor (58) connected to the basket rotating shaft (54) to rotate the basket rotating shaft (54). In addition, the controller 60 includes a controller 60 for receiving and comparing the digital signals from the first encoder 50 and the second encoders 56 and 57 so that the DC motor 58 rotates the basket rotation shaft 54. do.

As is well known, an encoder is an element that converts an analog signal into a digital signal, and the first encoder 50 converts an analog signal according to the shaft rotation of the handle shaft 52 into a digital signal, and a second encoder. 56 and 57 serve to convert an analog signal according to the shaft rotation of the basket rotation shaft 54 into a digital signal.

The first encoder 50 and the second encoder 56, 57 are connected to the controller 60, respectively, and the digital signals generated from each are transmitted to the controller 60, compared, and controlled so that the comparison value is maintained within the set range. . Such control is performed by rotating the basket rotating shaft 54.

Meanwhile, a bevel gear 62 is fixed to the basket rotating shaft 54, and another bevel gear corresponding to the bevel gear 62 is formed on the driving shaft of the DC motor 58 to rotate the basket rotating shaft 54. 64) is fixed. Therefore, when the DC motor 58 is driven, the basket rotating shaft 54 rotates to rotate the baskets 12 and 14. The DC motor 58 is connected to an external power source and the electricity delivered to the DC motor 58 is connected and disconnected by the controller 60.

When the difference between the digital data value from the first encoder 50 and the digital data value from the second encoders 56 and 57 compared to the inside of the controller 60 is out of the preset range, the controller 60 ) Operates the DC motor 58 so that the digital data values from the second encoders 56 and 57 are close to the digital data values of the first encoder 50. The smaller the set range is, the better and ultimately it is desirable to match both digital data values.

In addition, the controller 60 is connected to the DC motor 58 on both sides to allow the DC motor 58 to match the digital data signals transmitted from the first and second encoders 50, 56, 57. 54).

As a result, in the steering apparatus of the present invention configured as described above, when the steering wheel 10 is rotated to change the direction, the DC motor 58 moves the turning baskets 12 and 14 in response to the rotation amount of the handle shaft 52. By driving, the direction of the armored vehicle is switched. This operation causes the controller 60, which continuously compares the digital data signals from the first encoder 50 and the second encoders 56 and 57, to adjust the amount of rotation of the handle shaft 52 and the basket rotation shaft 54. By comparison, the amount of rotation between the two always corresponds to each other during operation.
