Description

[Detailed Description of the Invention] The present invention relates to an actuating device, and more specifically, an adjustable member in which a cylindrical cam having a knob at one end is rotatably fitted is attached to a pair of mounting members spaced apart from each other. The present invention relates to an actuating device for rotating the cylindrical cam, which is used in a connection structure connected by a bolt extending between the pair of mounting members passing through the cylindrical cam.

For example, the front wheel of a FF vehicle is supported by a suspension system equipped with the above-mentioned coupling structure, and the camber adjustment is performed by engaging a tool with the knob of the cylindrical cam and rotating the cylindrical cam, thereby adjusting the angle of the knuckle, which is the member to be adjusted. It is done by changing. However, in the case of FF cars, due to its structure, the knob of the cylindrical cam is located near the wheel disc or the balance weight attached to this wheel disc, so tools cannot be used while the front wheel is attached to the wheel disc. There is. Therefore, it is necessary to remove the front wheel from the knuckle each time when adjusting the camber. However, it is not possible to accurately adjust the camber with the front wheel removed from the nut. Therefore, remove the front wheel from the knuckle, turn the cylindrical cam a certain amount, then attach the front wheel to the knuckle and measure. If the proper camber is not obtained, repeat the above operation to adjust the camber. , which is a complicated task.

Therefore, an object of the present invention is to provide an actuating device that can rotate the cylindrical cam even in a narrow space.

Another object of the present invention is to provide an actuating device that can quickly and easily adjust the camber of the front wheel when used in the above-described suspension system coupling structure.

In the present invention, a cylindrical cam having a knob at one end is rotatably fitted into a member to be adjusted, and the cylindrical cam is extended between the pair of mounting members through the cylindrical cam. An actuating device used in a bolted connection structure to rotate the cylindrical cam. This actuating device includes a main body having a hole at one end for receiving the head of the bolt to be rotated about the bolt, and a notch that is swingably attached to the main body and receives the knob of the cylindrical cam. and an arm having an arm. The main body is provided with a tool engaging portion.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the actuating device of the present invention is used in a coupling structure 14 in which a member to be adjusted 10 is coupled to a pair of mounting members 12, 12 spaced apart from each other. The member to be adjusted 10 is, for example, a car nut. On the other hand, in the illustrated example, the pair of mounting members 12 consist of both ends of an absorber shell 18 that surrounds and is fixed to the lower end of the shock absorber 16.
It projects parallel to the

A front wheel is attached to the member to be adjusted 10, which is a nut, by a structure known per se. This front wheel camber adjustment is performed by changing the angle of the member to be adjusted 10 with respect to the mounting member 12 and therefore the shock absorber 16. For this purpose, a cylindrical cam 20 is rotatably fitted into the member to be adjusted 10, as shown in FIG. This cylindrical cam 20 has a knob 22 at one end, and a through hole 24 is bored at a position eccentric to the center of the cylindrical surface. A bolt 26 passing through this through hole 24 and a through hole provided in the member to be adjusted 10 (not shown)
The member to be adjusted 10 is connected to the pair of mounting members 12 by a bolt 28 passing through the bolts 28 . When adjusting the camber, both bolts 26 and 28 are loosened, a tool is engaged with the knob 22 of the cylindrical cam 20, and the cylindrical cam 20 is rotated via the knob 22. In this case, the above problem occurred.

The actuating device 30 of the present invention includes a main body 32 and an arm 34, as shown in FIGS. 3 and 4. The main body 32 has a generally cylindrical shape as a whole, and is provided with a hole 36 extending in the axial direction from the center of an end surface 33 at one end thereof. This hole 36 receives the head 38 of the bolt and when the body 32 is rotated,
It functions to roughly position the main body 32.
It is sufficient that the hole 36 loosely receives the head 38 of the bolt and is large enough to cause some wobbling when the main body 32 rotates. Depending on the mounting location of the cylindrical cam 20, the hole 36 may receive a nut that is threaded onto the bolt.

A tool engaging portion 40 is provided at an end of the main body 32 that is different from the end where the hole 36 is provided. In the illustrated example, the tool engaging portion 40 is a square hole. A square column portion 44 at the tip of a torque wrench 42 is fitted into this tool engaging portion 40 . Tool engaging part 4
0 takes on different forms depending on the tool used. For example, when using a tool such as a spanner, a portion having the same width across flats as the head of the bolt is formed on the outer peripheral surface of the main body 32 to serve as a tool engaging portion. When the tool used is a torque trench 42, the tool engaging portion 40 preferably includes a hole 48 for receiving a positioning ball 46 provided in a square column portion 44 of the torque trench. When this ball 46 is fitted into the hole 48, the torque wrench 42 is securely attached to the main body 32.
It will be installed on.

The arm 34 integrally includes a support portion 50, an intermediate portion 52, and a claw portion 54, and has a substantially L-shape as a whole. A support 50 is guided into the bore 36 through a slot 56 provided along the axis of the body 32. A shaft 58 fixed to the main body 32 is loosely inserted into the support portion 50, and the support portion 50, and hence the arm 34, can swing relative to the main body 32.
When the arm 34 is configured to be swingable in this way,
When the actuating device 30 is attached or detached, the arm 34 can be moved upwardly from the mounting member 12, as shown by the solid line in FIG. Accordingly, the pawl portion 54 can engage the knob 22 even if the upper end of the mounting member 12 and the upper end of the knob 22 are approximately at the same level.

In the illustrated example, the support portion 50 is connected to the tool engaging portion 4.
An inclined surface 60 is provided at a portion facing 0. When the tip of the torque wrench 42 comes into contact with this inclined surface 60, the arm 34 is held at the position shown by the imaginary line in FIG. As will be described later, when the actuating device 30 attempts to move the cylindrical cam 20 and the movement of the cylindrical cam 20 is heavy, the arm 34 is rotated in a direction away from the cylindrical cam 20. However, this is preferable in order to prevent this.

The pawl portion 54 includes a notch 62, and pawls 64 are formed on both sides of the notch 62. The knob 22 of the cylindrical cam 20 is received in this notch 62. Then, the pawls 64 will be located on both sides of the knob 22, restraining the knob. A pair of stoppers 66 are provided near the end surface 33 of the main body 32 at positions on both sides of the intermediate portion 52 of the arm 34.
is provided. This stopper 66 takes on the load applied to the arm 34 when the cylindrical cam 20 is rotated, and prevents the arm 34 from bending.

When using the actuating device 30 of the present invention, the arm 34 is swung upward and its end surface 33 is brought into contact with the outer surface of the mounting member 12 so that the head 38 of the bolt enters the hole 36 of the main body 32. . Thereafter, the arm 34 is swung downward, and the knob 22 of the cylindrical cam 20 is inserted into the notch 62 of the claw portion 54, as shown in FIG. Insert a torque wrench into the tool engaging portion 40, and use the torque wrench to tighten the knob 22.
The cylindrical cam 20 is rotated through the member to be adjusted 10.
Make adjustments.

According to the present invention, since the cylindrical cam can be operated even in a narrow space, it is possible to quickly and easily adjust the position of one member relative to another. Therefore, when the actuating device of the present invention is used in the connection structure of an automobile suspension system, it is not necessary to attach and detach the wheel each time the camber is adjusted.
Adjustment work can be significantly shortened.
