本発明は、不等長ドライブシヤフトを有する前
輪駆動型自動車のステアリング装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steering device for a front wheel drive motor vehicle having a driveshaft of unequal length.
一般に、不等長ドライブシヤフトを有する前輪
駆動型自動車においては、左右輪の下反角が異な

メントに差が現われ、ドライブシヤフトの長い側
にハンドルを取られる欠点がある。 In general, in front-wheel drive vehicles with drive shafts of unequal length, the anhedral angles of the left and right wheels are different, so there is a difference in moment around the king pin axis between the left and right wheels during driving, and the steering wheel is steered toward the longer side of the drive shaft. There are drawbacks.

である。 In order to solve the conventional problem of having the handle on the long side of the drive shaft,
No. 22225 proposes that the center offset amount of the wheel on the longer side of the shaft be larger than that on the other side, but the asymmetry of the center offset amount of the wheel can cause stiffness and difficulty in gripping the steering wheel during braking. There are problems that arise. Also,
In Japanese Utility Model Publication No. 49-20039, it was proposed to tilt the rotation center axis of the differential in the vertical direction, and in Japanese Patent Application Laid-Open No. 54-138235, the angle of inclination of the shorter drive shaft with respect to the left and right drive axles was reduced. Although it has been proposed to tilt the differential, it is undesirable to tilt the differential or the entire power unit because of the structure of the vehicle.

るようにしたことである。 The present invention has been made in view of the above-mentioned conventional problems, and provides a steering device for an automobile that eliminates the steering wheel grip during driving and has high straight-line stability by adding a simple configuration to the conventional steering device. The purpose is to
Its structural features include, in automobiles with driveshafts of unequal length, the tie rod on the long driveshaft side is divided, and an elastic member is interposed between the two divided tie rods.
Additionally, a stopper is provided to limit the change in length of the tie rod in only one direction, thereby increasing the amount of toe-in of the front wheel on the longer drive shaft side during driving.

方向には相対変位しない。 Embodiments of the present invention will be described below based on the drawings. In the first embodiment, as shown in FIGS. 1 and 2, tie rods 2 and 4 are connected to drive shafts 6 and 8.
It is placed further back. The differential gear 10 has a front right wheel 24a and a left wheel 24b.
is located near the right drive shaft 6 and therefore the right drive shaft 6
is longer than the left drive shaft 8.
The tie rods 2 and 4 are connected by a center link 11, and the center link 11 is connected to a steering wheel 16 via a steering gear housed in a steering case 12 and a steering column 14. A ball joint 18 and a knuckle arm 2 are attached to the outer ends of the tie rods 2 and 4.
Wheels 24a and 24b are rotatably connected to each other via a strut 26, and the upper part of the knuckle arm 20 and the vehicle body are connected to each other by a strut 26. The tie rod 2 on the same side as the long drive shaft 6 is 2a, 2
b, and an elastic connecting device 28 is interposed in between. As shown in FIG. 3, the elastic coupling device 28 has a small diameter end portion 32 of the tie rod 2b inserted into a hole 30 at the end of the tie rod 2a. At the root portion of this tip small diameter portion 32, a root small diameter portion 34 having a smaller diameter is provided. At the end of the tie rod 2a, there is a tip small diameter portion 32 larger in diameter than the root small diameter portion 34.
The lid member 3 has a hole 36 with a diameter smaller than the diameter of the lid member 3.
8 is fixed. Then, the tip small diameter portion 32 of the tie rod 2b connects to the hole 30 at the end of the tie rod 2a.
An elastic member 40 made of rubber or a spring is suitably compressed and inserted between the small diameter portion 32 and the lid member 38, which is formed when the lid member 38 is pushed in until it hits the bottom (the state shown in FIG. 3). The elastic coupling device 28 having the above structure is relatively displaced in the direction of separating the tie rods 2a, 2b from each other, but not in the direction of pushing the tie rods 2a, 2b together. No relative displacement.

れ、直進安定性が向上する。 In the above configuration, the elastic coupling device 28 expands due to the tension load generated on the tie rod during driving, and the amount of toe-in of the right wheel increases as shown by the dotted line in FIG. As a result, the handle is not removed to the side of the long drive shaft 6 when driving.
This is canceled out by the increase in toe-in during driving, and straight-line stability is improved.

施例と同一の符号を付すのみでその説明を省く。 In a second embodiment of the present invention, as shown in FIGS. 4 and 5, tie rods 52 and 54 are located forward of drive shafts 56 and 58. Further, as shown in FIG. 5, the elastic coupling device 60 has a tie rod 52a that is
Inside the hole 62 at the end of the tie rod 52
The small diameter end portion 64 of b and the elastic member 66 are interchanged. Therefore, the elastic coupling device 60 with the above configuration
5 relative to the state shown in FIG. 5, there is a relative change in the direction of pushing the tie rods 52a, 52b together, but there is no relative displacement in the direction of separating the tie rods 52a, 52b from each other. Since the other configurations of the second embodiment are the same as those of the first embodiment, the same reference numerals as those of the first embodiment are used in the drawings, and the explanation thereof will be omitted.

消され、直進安定性が向上する。 In the above configuration, the elastic coupling device 60 is shortened by the compression load generated on the tie rod during driving, and the toe-in amount of the right wheel increases as shown by the dotted line in FIG. As a result, the steering wheel being pulled toward the long drive shaft 6 during driving is canceled out by the increase in toe-in during driving, and straight-line stability is improved.
