Abstract

PURPOSE:To prevent rear wheels from being steered exceeding the predetermined steering angle in the same direction as the steering angle of front wheels by providing a device changing in response to the steering angle of the front wheels and limiting the steering angle of the rear wheels. CONSTITUTION:A rectangular frame-like cam member 60 is arranged movably in the longitudinal direction between front wheels 18 and rear wheels 28 by being supported by four pairs of rollers 62. The front frame section of the cam member 69 is connected to a rod 66 fixed to a piston rod 14 on the front wheels 18 side via a cable 64, and two congruent and trapezoidal projections are protruded in the right and left directions and are formed point-symmetrically on the inner side surface of the cam member 60. A rack 90 is arranged movably in the right and left directions below the cam member 60, a rack section 92 is formed on one end, and a pin 94 is erected on the other end. A pinion 34 fixed to a rotary shaft 30 is engaged with the rack section 92. Thereby, when the steering quantity of a steering wheel 10 is within a range less than a predetermined value, the rear wheels 28 are steered in the same direction as that of the front wheels 18, thus the rear wheels are prevented from being steered exceeding the predetermined steering angle in the same direction as the steering angle of the front wheels.

Conventionally, in this type of steering system, which steers the rear wheels according to the steering status of the front wheels in order to improve the driving performance of the vehicle, a link type steering system that connects the front wheels and the rear wheels with a link mechanism is used. There are also hydraulically driven types that control the rear wheels using hydraulic pressure. However, while the hydraulic drive type has the advantage of being able to control the rear wheels with a large degree of freedom, it does not have a link mechanism or other element that regulates the rear wheel steering device, so the servo valve in the hydraulic system is If a failure occurs in the servo valve or the control circuit that controls it, and the servo valve is fixed at a position other than the neutral position, the steering status of the front and rear wheels will be inconsistent, causing the vehicle to move unexpectedly. There is a risk of the vehicle moving in the opposite direction, especially when the rear wheels are steered in the same direction as the front wheels, as the vehicle is often traveling at relatively high speeds, so failures may occur in the control circuit, etc. If the rear wheels are steered excessively in the same direction as the front wheels beyond a predetermined relationship, there is a risk of a major accident such as a rollover.

The present invention solves the above-mentioned problems of conventional products,
Even if a failure occurs in the control means such as the servo valve in the hydraulic system of the rear wheel steering control device that controls the steering of the rear wheels based on the steering of the front wheels, or the control circuit that controls the same, the present invention can be applied. It is designed to prevent the rear wheels from being steered in the same direction as the front wheels beyond a predetermined relationship by providing a limiting device that limits the steering of the rear wheels, and has a simple structure. The object of the present invention is to provide a four-wheel steering device for a vehicle suitable for women.

In the neutral position (when the front wheel IB is not steered to the left or right), the relative position of the pin 94 and the cam member 60 is such that the pin 94 is located at the 6th angle of the flat surfaces 82 and 12 of the cam portion 60. It is arranged so as to be in contact with the surface 84 and the end on the 14 side.
A fixed pinion 34 is engaged with the pinion.

Now, assuming that the steering wheel 10 is turned to the right, a control valve (not shown) in the power cylinder 12 is actuated according to the amount of turning, and the piston rod is moved by the pressure oil supplied by the hydraulic pump 42. 14 moves to the left and steers the front wheel 18 to the right. When the piston rod 14 moves to the left, the cam member 60 moves forward via the cable fj4.

When the amount of steering of the steering wheel 10 detected by the sensor 46, that is, the turning angle θH of the front wheels 18, is within a range smaller than the predetermined angle θ1, the controller 48 causes the hexameter 52 to turn to the right. ), rotating shaft 30
rotates to the left (as seen from the rear), actuates the control valve (not shown) in the power cylinder 22, and the piston rod 24 is moved to the left by the pressure oil supplied by the hydraulic tanabata 42. Then, the rear wheels 28 are steered to the right, that is, in the same direction as the front wheels 10.

When the rotary shaft 30 rotates to the left, the rack 90 moves to the right, but in a normal γ machining state, the amount of movement of the rack 90 is such that the pin 94 and the third inclined surface 84 do not engage with each other.
However, in the event that the controller 48 malfunctions or the landing gear does not operate normally, the rear wheels 28 may be excessively steered to the right by more than a predetermined angle. Movement of the pin 94 is restricted by the inclined surface 84 so that the pin 94 does not move.

When the steering wheel 10 continues to turn to the right and the steering angle θH of the front wheels 18 reaches a predetermined value, the rotation of the motor 52 is reversed by a signal from the controller 48, and the rear wheels 28 return to the straight-ahead position. When the steering angle θ of the front wheels reaches a certain angle, the system returns to the straight-ahead position, but even if the control means fails as described above during the return, the pin 94 Since the movement is restricted by the fourth flat portion 8G, there is no possibility that the rear wheels will be steered excessively beyond a predetermined range.

The chart shown in FIG. 3 shows the front wheel steering angle ω11 and the rear wheel steering angle θl? of a vehicle equipped with the limiting device of the present invention. Tolerance with 7
As the front wheel steering angle θ increases, the allowable range of the rear wheel steering angle θB is limited by the slope 14 or 84 of the MtJ cam member 60 until a predetermined steering angle OI. increases, but after that, the front wheel steering angle 0H increases (even if it is 2, the permissible angle range of the rear wheel steering angle θR remains constant, and no matter what trouble occurs to the control means, the rear wheels will be kept in the same direction as the front wheels). The steering angle of the rear wheels is limited by the flat part '16 or t16 of the cam member 60 of the limiting device, so that the steering angle of the rear wheels does not exceed the value indicated by the diagonal line in the diagram. The inside part indicates that the steering is not performed.

Furthermore, when the steering angle of the front wheels increases further, normally in a four-wheel steering vehicle, the steering angle of the rear wheels exceeds the neutral position and is usually steered in a direction opposite to the steering angle of the front wheels. However, even in this case, the inclined surface 74°8 formed on the cam member 60
4 and the inclined surfaces 78 and 88 on the opposite side from the flat portions 76 and 86 restrict the movement of the pin 94, thereby preventing excessive steering.

As described above, the limiting device t of the present invention mechanically changes the operable range of the rear wheel steering control device in accordance with the front wheel steering angle caused by the operation of the steering device that steers the front wheels. Therefore, even if there is a failure in the control device of the rear wheel steering device or the control means of the servo system, the steering of the rear wheels will be limited to the specified range. It's 2'L so it's completely safe.
