Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an auxiliary tool for mounting a camber, a caster, a kingpin gauge with a magnet for measuring wheel alignment of an automobile.

<Prior art> Recent automobiles are required not only to be comfortable in the indoor space but also to be more advanced in terms of driving stability, and along with this, light alloy wheels are also being developed and utilized tremendously. Wearing rate is high.

In the inspection and measurement work of wheel alignment related to the stable running of such a vehicle, apart from expensive inspection line equipment equipped with an advanced measurement system using various sensors, a magnet that is a low-priced and simple measuring instrument The camber, caster, and kingpin gauges are generally used as one of the tools for certified factories, which are equipped and practically used in many designated or certified automobile maintenance factories.

However, due to the recent diversification of vehicle types and the increase and popularization of 4WD and F / F mechanisms, many types of vehicles cannot be structurally supported by conventional camber, caster, and kingpin gauges with magnets. The magnet part for use does not fit the size of the mounting part of the wheel hub and can not be used at all, or even if it can be mounted, the equivalent area of the magnetic magnetized part of the core is small, so the centering holding becomes unstable Therefore, the measured values are liable to be misaligned during the work, which is an obstacle to the measurement work and becomes a problem.

In the case of light alloy wheels, which have a higher wear rate, the clip and bolt hole periphery is thicker due to its structural function, and the hub hole in the center often has a small diameter, so the magnet part that is centered with the tip of the spindle or drive shaft. I couldn't use it because I didn't enter. In addition, since the wheel is of course made of non-ferrous metal, it cannot be used as a magnet.

Therefore, in order to attach the camber, caster, kingpin gauge with magnet itself at the time of measurement, temporarily attach an iron plate washer of the same diameter as the magnet to the spindle or the tip of the drive shaft in a concentric circle. All of these methods are both cumbersome and inefficient, such as stably adsorbing and fixing the magnet part, or in the case of a vehicle equipped with light alloy wheels, perform the required measurement work such as exchanging with steel wheels of the same size. is there.

<Problems to be solved by the present invention> The problem to be solved is that the camber, caster, and kingpin gauges with magnets, which have been generally installed and used in many designated and certified automobile maintenance factories, have recently been diversified. It is not possible to adapt to the changing vehicle type and specifications, etc., and it is not possible to adsorb and fix the magnet part for attaching the measuring instrument to the wheel hub of each specification of each car as prescribed.

<Means for Solving the Problems> The present invention is integrally configured at the center position of the centering / base of the pedestal where the tip is opened in three directions according to the inner diameter of the center hole such as the hub hole of the unspecified wheel. The most main feature is that the iron disk with a center point is fixedly held in a centering circle concentric with the wheel. As a result, the magnet part of the conventional camber, caster, and kingpin gauge with magnet can be attracted to the iron disk with the center point, and each measurement work can be performed according to the regulations as in the past. We have achieved the objective of being able to handle all types of wheels and hub sizes and light alloy wheels and hub sizes for each vehicle in the model and specifications.

Concave projections with pin holes 5'that configure the other end of the equal length pedestal 5 forming the claw 6 at the tip at positions of 120 degrees around the circumference of the thick disc 3 3A are attached by pins 5 "respectively, and the tip claw portions 6 of the pedestal 5 can be unfolded in three directions along the diameter extension line of the disc 3 in advance, and the center position of the disc 3 is set. Center to be installed in
At the upper end portion of the shaft 2 that is combined with the bush portion 3 ', there is an iron material disc 1 having a center point portion 1'on the upper surface integrally formed with the shaft 2 in a concentric circle and forming a knurl 1 "around the circle. The disc 3 is rotatable on the upper side of the plate 3
The O-ring plate 8 set in the ring groove 2'provided on the lower shaft 2 portion prevents the disk 3 from being pulled out, and the lower shaft 2 portion has a required length. The male screw portion 2'is formed.

The female screw portion 4 ″ which is to be mated with the male screw portion 2 ′ is provided with a central hole 4 ′.
The protrusions 4B with pin holes 7'constituting 120-degree intervals around the circle of the small disk 4 formed in the two sides are sandwiched, and the ends of the columns 7 are freely attached by the pins 7 " If the intermediate predetermined position between the end portion and the outer pedestal 5 is held at the same length and freely connected by the pin 7 ″ as well, the male screw portion 2 ′ is rotated by the shaft 2 to move up and down through the female screw portion 4 ″. In response to the movement of the small disc 4 which is displaced, the lower end of the pedestal 5 that is connected to the column 7 that interlocks in the three directions performs the same opening / closing operation of equal length in three directions on the diameter extension line of the disc 3. be able to.

By doing this, by rotating the iron material disc 1 with the center point portion 1 ′, the pedestal 5 tip claw portion 6 inserted into the center hole such as the hub hole of the wheel 11 of each size of the automobile can be made. By the centering operation of opening the legs according to the inner diameter value, the iron disk 1 with the center point portion 1 ′ can be centered and held concentrically with the wheel 11. At this time, the centering fixing and holding operation of the tip claw portion 6 of the pedestal 5 that opens in the center hole such as the hub hole of the wheel 11 is stably maintained by the jacking effect of the male screw portion 2'and the female screw portion 4 ".

In using the device of the present invention, after the predetermined preparation required for the automobile to be measured, first, the center point portion 1'of the auxiliary tool is measured according to the inner diameter value of the center hole of the hub hole or the like of the wheel to be measured.
Rotate the attached iron disk 1 slightly to the right and insert the claw 6 at the tip of the pedestal 5 that extends in three directions into the center hole such as the hub hole of the wheel 11 so as to straddle the drive shaft 9 and the nut 10 and The tip of the part 6 is applied to the surface of the bottom hub 17 to lightly press the entire auxiliary tool to stabilize it, and the iron disc 1 with the center point part 1 ′ may be further rotated to the right while pressing the pedestal 5. At that time, if the tip claw portion 6 of the pedestal 5 that interlocks and develops in accordance with the inner diameter value of the hub hole is pressed and fixed to the peripheral surface of the inner diameter bottom portion, the iron material disc 1 with the center point portion 1'will not rotate, and as it is. The wheel 11 is concentric with the wheel 11 and fixedly held by the centering. Next, the magnet 15 at the base of the conventional camber / caster / king pin gauge 14 may be attracted to the outer surface of the iron disk 1. that time,
The tip of the center guide pin 16 in the magnet 15 is applied to the center point portion 1'on the outer surface of the iron disk 1, so that the center position does not shift during attraction.

Removal after the measurement may be performed in the reverse order of mounting. After removing the camber, caster, and kingpin gauge 14 with the magnet, the iron disc 1 may be turned to the left while pressing the pedestal 5. At this time, since the development of the claw 6 at the tip of the pedestal 5 in the hub hole is closed and separated from the inner peripheral surface, the auxiliary tool can be easily removed.
