BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front wheel drive vehicle for driving a front wheel, and more particularly to a rear wheel steering system of a current driven vehicle for steering the rear wheels of a front wheel drive vehicle.

In parking a front wheel drive car in a narrow parking space in a city, first, the front wheel is steered and the front part of the car is positioned at the front of the parking space, and then the rear wheel is independently steered to rear the rear part of the car. It is hoped that a function that can be located at is performed.

The present invention has been proposed in order to realize the above-mentioned matters, and an object of the present invention is to park a front wheel drive car in a narrow parking space in a city center, first of all, steering the front wheel to position the front part of the car at the front of the parking space. After the rear wheels are independently steered, the rear wheel of the car can be positioned at the rear of the parking space, so that the front-wheel drive car can be easily parked in the narrow parking space of the city. It is to prevent contact accidents that may occur when parking in a narrow parking space.

In order to achieve the above object, the present invention, the tie rod assembly is installed on the rear wheel of the front wheel vehicle, the tie rod assembly is a relay rod connected inward to the inner ends of the tie rods on both sides of the tie rod and the middle thereof; The outer end of the tie rod is connected to the knuckle arm of the tire to drive the tire, and one end of the relay rod is connected to one finger of the bell crank while the other end of the relay rod is idle arm. It provides a rear wheel steering system of the front-wheel drive vehicle, characterized in that the connection to the bell crank tapinger is connected to the controllable hydraulic cylinder.

According to the rear wheel steering system of the front-wheel drive car of the above-described configuration, in parking a front-wheel drive car in a narrow parking space in the city, the front wheel is first positioned by steering the front wheel and the rear wheel is independently By steering the vehicle in such a way that the rear part of the car can be located at the rear of the parking space, the front-wheel drive car can be easily parked in the narrow parking space of the city and the parking space is narrow in the city. It also has the effect of preventing contact accidents that may occur.

Hereinafter, a preferred embodiment of a rear wheel steering system of a current driven vehicle according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a layout view of a preferred embodiment of a rear wheel steering system of a front wheel drive vehicle according to the present invention, and FIG. 2 is an exploded perspective view of the embodiment.

Reference numeral 1 designates a body frame. The front wheel 3 to which the tie rod assembly 2 is connected is installed at the front of the body frame 1, and the rear wheel 4 is installed at the rear of the body frame 1.

According to the invention, the tie rod assembly 5 is also installed in the rear wheel 4. The tie rod assembly 5 is a relay rod (5) connected inward to inner ends of the tie rods (5-2 and 5-3) and intermediate ends of the tie rods (5-2 and 5-3) in the middle thereof. It consists of 4). On the other hand, the outer end of the tie rods (5-2 and 5-3) is connected to the knuckle arm of the tire (not shown) to drive the tire. The one end of the relay rod 5-4 connects the one finger 6-2 of the bell crank 6, and the other end of the relay rod 5-4 connects the idle arm 7 to the other end of the relay rod 5-4. Do it. In addition, the hydraulic cylinder (8) is connected to the tapping finger (6-3) of the bell crank (6). The hydraulic cylinder 8 is capable of controlling its operation by known means.

According to a preferred embodiment of the rear wheel steering system of the front wheel drive vehicle according to the present invention as described above, by controlling the hydraulic cylinder (8) to rotate the bell crank (6) the tie rods (5-2 and 5) By moving -3) left and right, the rear wheels 4 of the front wheel drive vehicle can be freely steered.

According to a preferred embodiment of the rear wheel steering system of the front wheel drive vehicle according to the present invention as described above, in the present invention, in the parking of the front wheel drive vehicle in a narrow parking space in the city, first steering the front wheel (3) After placing the front part of the car at the front part of the parking space, the rear wheel 4 can be steered independently so that the rear part of the car can be located at the rear part of the parking space. It is possible to easily park a wheel drive car and also to prevent contact accidents that may occur in parking in a narrow parking space in the city.
