Description

  The present invention relates to an improvement in a mounting structure for a steering arm and a tie rod arm of a vehicle.

  In the conventional mounting structure of the steering arm, male screws are formed at both ends of the stud bolt, the stud bolts are inserted into the screw holes formed in the knuckle through the through holes formed in the steering arm, and the castle is attached to the male screw at the other end. The steering arm and the knuckle were connected by screwing the nut. Furthermore, the stud bolt and the castle nut are passed through and fixed with a split pin to prevent the castle nut from loosening.

  The tie rod arm and knuckle were fastened in the same manner as described above.

  However, with this mounting structure, when the split pin is mounted, the positions of the stud bolt hole and the castle nut hole must be matched while maintaining the specified torque, which requires work. Further, since the split pin is attached in a narrow space, the work efficiency is poor. Instead of attaching a split pin, there are some which caulk the stud, but in this case, the caulking work is excessive and the work efficiency is deteriorated.

  In addition, there was a problem similar to the above in the attachment of the tie rod arm.

  Therefore, the present invention provides a steering arm and tie rod arm mounting structure that does not require split pin mounting and improves work efficiency.

  In order to achieve the above object, according to a first aspect of the present invention, there is provided a steering arm mounting structure in which a steering arm and a knuckle of a vehicle are fastened via a bolt, and a loosening prevention sealing material is applied to the male screw at the end of the bolt. The bolt is passed through the bolt hole of the steering arm, and the male screw of the bolt is screwed into the screw hole of the knuckle.

  In a second aspect based on the first aspect, the steering arm is a T-type steering arm.

  In a third aspect based on the first aspect, the steering arm is an I-type steering arm.

  According to a fourth aspect of the present invention, there is provided a tie rod arm mounting structure in which a tie rod arm and a knuckle of a vehicle are fastened via a bolt, a seal material for preventing loosening is applied to a male screw at an end of the bolt, and the bolt is a bolt hole of the tie rod arm. And screw the male screw of the bolt into the screw hole of the knuckle.

  According to the present invention, since the conventional stud bolt driving operation is eliminated, the setting of the part number due to the difference in the studs can be omitted, and the working efficiency can be improved. In addition, since the work of assembling the split pins, which has been done in the past, is eliminated, it is possible to eliminate the troublesome work in a narrow space, such as the work of aligning the hole positions of the castle nut and stud with the specified torque. Can be improved. Further, the caulking work when using the caulking stud is not necessary. Furthermore, in the conventional mounting structure, three points of the stud, the castle nut, and the split pin are necessary. However, since this is only one bolt, the number of parts can be reduced, and the cost can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a view showing a mounting structure of a T-type steering arm.

  In FIG. 1, a front axle 8 connected to a chassis (not shown) is coupled to a hub assembly 5 on which a tire is mounted.

  A T-type steering arm 1 connected to a steering (not shown) is fastened to a knuckle 2 by two bolts 3. The knuckle 2 rotates about the king pin 6 with the rotation of the T-type steering arm 1 to rotate the hub assembly 5.

  The T-type steering arm 1 is provided with a through hole 9. The knuckle 2 is provided with a screw hole 10 in which a female screw is formed, and a bolt 3 penetrating the through hole 9 is screwed into the screw hole 10.

  FIG. 2 is a view showing the bolt 3 of the present invention.

  The head 3a of the bolt 3 is formed in a hexagon, and the shaft end portion is formed in the male screw portion 3b. The bolt 3 is fixed to the screw hole 10 by applying a seal material for preventing loosening to the male screw part 3 b of the bolt 3 and screwing it into the female screw part of the screw hole 10. For example, TB2403 manufactured by ThreeBond Co., Ltd. is used as the sealing material for preventing looseness.

  The loosening prevention seal material firmly fixes the bolt 3 to the screw hole 10 by filling the gap between the male screw portion 3b of the bolt 3 and the female screw portion of the screw hole 10 and solidifying the gap. For this reason, the bolt 3 is prevented from loosening even if it receives a load or vibration, and the T-type steering arm 1 is securely coupled to the knuckle 2.

  As a result, the conventional stud bolt driving operation is eliminated, so that the part number setting due to the stud difference can be omitted, and the work efficiency can be improved. In addition, since the work of assembling the split pins, which has been done in the past, is eliminated, it is possible to eliminate the troublesome work in a narrow space, such as the work of aligning the hole positions of the castle nut and stud with the specified torque. Can be improved. Also, the caulking work is not necessary. Furthermore, in the conventional mounting structure, three points of the stud, the castle nut, and the split pin are necessary. However, since this is only one bolt, the number of parts can be reduced, and the cost can be reduced.

  As shown in FIG. 3, the knuckle 2 is connected via a tie rod 7 and a tie rod arm 4 that are coupled to another hub assembly (not shown). Similar to the T-type steering arm 1, the knuckle 2 and the tie rod arm 4 are fastened by a bolt 13 similar to the bolt 3 described above.

  Specifically, the bolt 13 that penetrates the through hole 19 formed in the tie rod arm 4 is screwed into the screw hole 20 formed in the knuckle 2.

  In the present embodiment, the T-type steering arm 1 is used as the steering arm, but an I-type steering arm 11 may be used as shown in FIG.

  As described above, in the present invention, in the mounting structure of the steering arm 1 for fastening the steering arm 1 and the knuckle 2 of the vehicle via the bolt 3, the sealing material for preventing looseness is applied to the male screw of the end 3b of the bolt 3, By inserting the bolt 3 into the bolt hole 9 of the steering arm 1 and screwing the male screw of the bolt 3 into the screw hole 10 of the knuckle 2, the conventional stud bolt driving operation is eliminated. Setting can be omitted and work efficiency can be improved. In addition, since the work of assembling the split pins, which has been done in the past, is eliminated, it is possible to eliminate the troublesome work in a narrow space, such as the work of aligning the hole positions of the castle nut and stud with the specified torque. Can be improved. Also, the caulking work is not necessary. Furthermore, in the conventional mounting structure, three points of the stud, the castle nut, and the split pin are necessary. However, since this is only one bolt, the number of parts can be reduced, and the cost can be reduced.

It should be understood that the invention is not limited to specific features. Accordingly, the present invention includes any forms or modifications within the scope of the claims as appropriately interpreted in accordance with the principle of equality.
