[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a tension rod mounted for a vehicle body mounting bracket and a lower arm of a front suspension.

[0002]

2. Description of the Related Art A tension rod A ' mounted between a lower arm of a conventional vehicle straddle-type front suspension and a vehicle body mounting bracket has a rubber bush 31 fitted to one end mounted on a vehicle body mounting bracket (not shown). And the other end is provided with a mounting portion 32 to the lower arm (not shown) of the front suspension, so that the tension rod A ' is disposed between the lower arm and the vehicle body bracket. When mounted, it was impossible to adjust the distance between the lower arm and the vehicle body bracket. Then, in the automobile manufacturer, the allowable range of the distance between the lower arm and the vehicle body bracket is specified for each model, but at present, the distance within the allowable range defined by the angle is defined. Also change the tension rod
A ' was not possible because A' was composed of a single rod.

[0003]

Since the change in the distance between the lower arm and the vehicle body bracket causes a change in the caster angle and is related to the maneuverability of the vehicle, each user aims at it. It is an object of the present invention to provide a tension rod capable of adjusting the maneuverability within a range defined by the manufacturer.

[0004]

Means for Solving the Problems In order to achieve the above object, the tension rod according to the present invention has a right outer periphery.
A socket is provided at one end with a bearing rod threaded with a thread.

After the length of the mounting rod is adjusted, the bearing rod and the socket body are fixed.

[0005]

According to the present invention, by rotating the socket body clockwise or counterclockwise, the bearing rod and the rod body move toward or away from the socket body, and the length of the tension rod is reduced. When the required length is obtained, the lock nut for the right-hand thread and the lock nut for the left-hand thread are tightened, and the bearing rod and the rod body are fixed to prevent movement. To secure.

Embodiment An embodiment of the present invention will be described with reference to the drawings.
In the drawing, reference numeral 1 denotes a bearing rod having a spherical bearing 2 fitted at its tip, and a right-hand screw 3 is engraved on the outer periphery of the bearing rod 1. Lock nut 4 is screwed. 5 is provided with a socket portion 6 at the tip , and is required in the axial direction from the end where the socket portion 6 is provided.
A socket body having a recess at the depth of the socket body, and the inner periphery of the recess of the socket body 5 has the bearing rod 1
A screw 7 to be screwed into the right screw 3 on the outer circumference of the above is engraved, and a left screw 8 is engraved on the outer circumference. Reference numeral 9 denotes a lock nut for a left screw which is screwed into the left screw 8 engraved on the outer periphery of the socket body 5 described above.

A rod body 10 is provided at one end with a recess for engraving on its inner periphery a screw 11 into which the socket body 5 can be screwed. The rod body 10 has a required length. Bolt holes 12, 12 for fixing to a lower link (not shown) of the front suspension are provided at the ends. Reference numerals 13 and 13 denote cotters provided at both ends of the spherical bearing 2 at the tip of the bearing rod 1 and the holding frame 14, respectively.
Reference numeral 15 denotes an insertion hole for a tension rod mounting pin formed in the cotters 13, 13 and the spherical bearing 1.

Since the tension rod A of the present invention is constructed as described above, a right-hand thread lock nut 4 is screwed into a right-hand thread 3 engraved on the outer periphery of a bearing rod 1 having a spherical bearing 2 fitted at the tip. And the bearing rod 1 into which the lock nut 4 is screwed.
Into a screw 7 engraved on the inner periphery of the socket body 5,
Further, the socket body into which the bearing rod 1 in which the lock nut 9 for the left screw is screwed to the left screw 8 engraved on the outer periphery of the socket body 5 and the lock nut 4 for the right screw is screwed as described above is screwed. A lock nut 9 for a left-hand thread is screwed into 5 and the socket body 5 is screwed into the rod body 10 to assemble the tension rod A.

The tension rod A assembled as described above is connected to the spherical bearing 2 of the bearing rod 1 of the tension rod A.
And fixed to the vehicle body mounting bracket with mounting pins inserted through the bolt insertion holes 15 of the cotters 13, 13.
A bolt is inserted into the mounting bolt holes 12, 12 at the other end of the rod body 10 of the tension rod, and then mounted and fixed to the lower arm of the front suspension. Attach one end of the tension rod A to the vehicle body mounting bracket and the other end to the lower arm of the front suspension as described above, and fix it to the vehicle body. If you want to change the distance between the vehicle body and the lower arm, fix the tension rod as described above. Then, the lock nut 4 for the right-hand thread screwed to the bearing rod 1 and the lock nut 9 for the left-hand screw screwed to the socket body 5 are loosened, and the socket part 6 is moved to the spherical bearing 2 side with a tool or the like. (Counter body side) and rotate counterclockwise.

As described above, when the socket body 6 is rotated counterclockwise by the socket part 6, the bearing rod 1 screwed into the socket body 5 moves in a direction away from the socket part 6, and at the same time, the socket body 5 The rod body 10 into which the thread is screwed also moves in a direction away from the socket part 6,
The tension rod A will extend as a whole. When the desired length is obtained, the right-screw rod nut 4 is tightened until it comes into contact with the socket part 6 to fix the bearing rod 1 and the socket body 5, and the left-hand lock nut 9 is brought into contact with the socket body 5. By tightening until it contacts, the socket body 5 and the rod body 10 are fixed, and the length of the tension rod A is reliably maintained.

When the tension rod A is to be reduced, the lock nut 4 for the right-hand thread and the lock nut 9 for the left-hand thread are first loosened. When the dial 5 is rotated clockwise, the bearing rod 1 and the rod main body are moved in a direction approaching the socket section 6 and contract as the tension rod A. And when you get the desired length,
In the same manner as described above, the lock nut 4 for the right-hand thread and the lock nut 9 for the left-hand thread are tightened until they come into contact with the socket portions 6, respectively, and the length of the tension rod A is securely fixed at a desired length.

As described above, according to this embodiment,
Conventionally, the length of the tension rod A, which cannot be adjusted, can be adjusted within a range determined for each type of manufacturer while the tension rod A is attached to the vehicle body. By shortening the length, it is possible to increase the caster angle to improve the straightness of the vehicle, and to improve the straightness of the vehicle. Therefore, it is possible to obtain maneuverability according to the purpose of the operator, such as to improve the maneuverability.
