Description

[Detailed Description of the Invention] This invention relates to an improvement of a tie rod clamp for fixing the threaded joint between a tie rod and an adjusting tube in a steering linkage of an automobile.

FIG. 1 shows a tie rod assembly to which this invention is applied, and tightening by a conventionally known tie rod clamp is shown as tightening at the right part. The tie rod assembly 1 is composed of tie rods 3 and 4 arranged on the left and right sides and an azimuth stiff tube 5 located between them. Tyrod 3,
4 is equipped with a ball joint at the end,
They are respectively coupled to a relay rod and a knuckle arm (not shown). Furthermore, the tie rods 3 and 4 are connected to the adjuster stem tube 5 by screwing.
The left and right screws are reverse threaded. For example, the tie rod 3 on the left side has a left-hand thread, and the tie rod 4 on the right side has a right-hand thread. Therefore, if the adjustment tube 5 is rotated while the rotation of the left and right tie rods 3 and 4 is restricted, that is, fixed, the length l of the tie rod assembly 1 will change by the pitch of the screw, and the length will be adjusted. (Toe-in adjustment)
can do.

Note that in order to fix the length positions of the adjusted tie rods 3, 4 and the adjusted length tube 5, clamps 2 are used to tighten them, but the conventionally common method is to tighten the tie rods 3 and 4 as shown on the right side of Figure 1. The narrow pressure type clamp 2 was simply tightened and fixed with bolts and nuts at the threaded portion of the radial tension tube 4 and the azimuth length tube 5.

Therefore, in the above-mentioned conventional tie rod assembly 1, the clamp 2 rotates together with the rotation of the adjuster stem tube 5 when adjusting its length, and after adjusting its length, it reaches the set length l. The position of the tightening bolt of the clamp 2 to be fixed in the axial direction is unknown, depending on the amount of adjustment. For this reason, after assembly, the tightening bolt of the clamp 2 was rotated to its proper position after assembly, but the assembly and workability were extremely poor.

This invention was made to solve the above-mentioned conventional problems, and aims to improve assembly and workability by positioning the clamp in the direction around the axis. .
According to this invention, in a tie rod clamp in which a tie rod and an adjuster tube for length adjustment are screwed together, and the screwed portion is tightened and fixed by a clamp, a bracket is attached to the tie rod. This is achieved by a tie rod clamp that is integrally attached in the right direction around the axis, and the bracket and the clamp are tightened together, thereby determining the tightening position of the clamp in the direction around the axis. .

Next, an embodiment based on the configuration of the invention described above will be described with reference to the drawings.

One embodiment of this invention is shown as a tie rod clamp on the left side of the tie rod assembly 1 shown in FIG. 1, and its detailed structure is shown in FIGS. 2 and 3. In this embodiment, a bracket 7 is attached to both the shaft portion 3a of the tie rod 3 and the narrow pressure type clamp 2. First, the bracket 7 is attached to the shaft portion 3a of the tie rod 3 by bending the left end of the bracket 7 at a right angle to the shaft portion 3a, as shown in the cross section of the fitted state of the two in FIG. The mounting bases 7a are fitted together, and the fitting is achieved by the fact that the brackets 7 are movable in the axial direction with respect to the tie rods 3 because the flat parts 8 partially cut out in the axial direction are provided on both sides. However, it is integrally positioned and attached in the direction around the axis. Next, bracket 7
To attach the clamp 2 to the right end of the bracket 7 (as shown in Figure 2), the bolt hole for passing the bolt 9 that attaches the clamp 2 to the right end of the bracket 7 is made to match the bolt hole of the clamp 2. The bolt 9 is passed through the bolt hole of the clamp 7 and the clamp 2, and then tightened with a nut 10. In this way, the clamp 2 is attached to the bracket 7 by the bolt 9.
However, since the bracket 7 is attached to the shaft portion 3a of the tie rod 3 in a positioned manner in the circumferential direction as described above, the clamp 2 is attached to the tie rod 3 in a positioned position in the circumferential direction. The result is that Therefore, the mounting position of the bolt 9 of the clamp 2 is determined by the positioning of the bracket 7 with respect to the tie rod 3. Therefore, the preferred mounting position of the bolt 9, for example, a position where a sufficient clearance can be secured from other parts, is appropriately selected for positioning. be able to.

In addition, a slit (not shown) is provided in the threaded part of the Asian steng tube 5 in the axial direction, and when the bolt 9 and nut 10 are tightened, pressure is applied by the clamp 2 to firmly fix the threaded part with the tie rod 3. It is something to do.

As detailed above, this invention uses the tie rod 3 to position the clamp 2 in the axial direction via the bracket 7, and ensures that the tightening bolts 9 and nuts 10 of the clamp 2 are positioned with sufficient clearance from other parts. Since the tie rod can be positioned at a position where the length of the tie rod can be secured, the ease of assembly and workability when adjusting the length of the tie rod can be greatly improved compared to the conventional method.
