Description
The present invention relates to a four-wheel drive dis connector device and a four-wheel drive vehicle including the device, and more particularly to a four-wheel drive disconnection device capable of accurately determining whether a four- And a four-wheel drive vehicle including the device.
Generally, a four-wheel drive vehicle requires a full-time four-wheel drive system, in which the main drive wheels and the longitudinal drive wheels always operate, and two-wheel drive as the main drive wheels. Part-time four-wheel drive system that drives the four-wheel drive by transmitting the driving force to the longitudinal drive wheels in accordance with the four-wheel drive system.
In addition, the four-wheel drive vehicle is divided into a system in which the power of the engine is distributed to the main drive wheel and the subordinate drive wheels to travel in four-wheel drive, a main drive wheel is driven by the engine, and a subordinate drive wheel is driven by the motor, .
Meanwhile, the longitudinal drive wheels are driven by four-wheel drive or power transmission from a power source such as an engine or a motor, and are blocked by two-wheel drive. At this time, the connection between the power source and the longitudinal drive wheels is engaged or disengaged, And a device for switching four-wheel drive is referred to as a disconnect device.
FIG. 1 shows a conventional disconnector device (Korean Patent Laid-Open Publication No. 2014-0013414). The conventional disconnector device includes an

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a four-wheel drive dis connector device capable of precisely measuring the position of a shift fork to prevent four- .
Another object of the present invention is to provide a four-wheel drive disconnector device capable of accurately measuring the position of a shift fork at a low cost and a four-wheel drive vehicle having the device.
In order to achieve the above object, the present invention provides a control system for controlling four-wheel drive of a vehicle by transmitting or interrupting a driving force between an input shaft connected to a driving source such as an engine or a motor and an output shaft separated from the input shaft, A four-wheel drive discrete connector according to any one of claims 1 to 3, wherein a sleeve is provided on an outer periphery of the separation shaft between the input shaft and the output shaft to axially move along an outer surface of the shaft and to fasten or unfasten the input shaft and the output shaft, A shift fork able to move the sleeve axially in contact with the sleeve; A screw coupled with the shift fork and reciprocating the shift fork in a direction parallel to the axial direction by rotation; An actuator for rotating the screw; And an angle sensor for measuring an angle of rotation of the actuator to control the operation of the actuator.
In a preferred embodiment, a reduction gear is provided between the angle sensor and the actuator, the reduction gear includes a first gear connected to the rotation shaft of the actuator, a gear connected to the rotation shaft of the angle sensor, 2 gear, and the first gear rotates more than one rotation while the second gear rotates once.
In a preferred embodiment, the rotation axis of the angle sensor rotates forward or reverse in a range between 0 and 360 degrees.
In a preferred embodiment, the angle sensor measures an angle between 0 and 360 degrees without exceeding 360 degrees.
In a preferred embodiment, the speed reducer is composed of a plastic spur gear.
In a preferred embodiment, the shift fork moves the sleeve while the rotation axis of the angle sensor rotates one rotation to engage or disengage the input shaft and the output shaft with each other.
The present invention also relates to an input shaft that rotates on the power of an engine or a motor; An output shaft connected to the longitudinal drive wheels; And the four-wheel drive discrete device for controlling four-wheel drive by engaging or disengaging the input shaft and the output shaft with each other.
The present invention has the following excellent effects.
First, according to the four-wheel drive discrete device of the present invention and the four-wheel drive vehicle including the device, since the position of the shift fork can be detected by measuring the rotation angle of the screw without using the linear sensor, There is an advantage that the possibility of failure of the four-wheel drive control due to abrasion or vibration of the contact portion can be reduced.
In addition, according to the four-wheel drive discrete device of the present invention and the four-wheel drive vehicle including the device, since the position of the shift fork can be detected by detecting the rotation of only a small angle by providing the reducer between the screw and the angle sensor, Can be reduced, and the cost can be reduced.
