The present invention relates to an axle detachable jig that is fixed to a jack and used to stably assemble and detach an axle that transmits power to a wheel of a vehicle.

In general, in the front engine rear wheel drive (RR) type vehicle, the driving wheel is located at the rear part, so the rear axle and the transmission transmit the driving force to the vehicle body and support the load applied to the rear part of the vehicle.

The axle rear axle consists of a drive train longitudinal gearbox, differential gear and rear axle and the rear axle housing that houses them.

The axle housing is an outer pipe having a rear axle and a fixed shaft that supports the rear load of the vehicle. In the center part, differential gear is built in, and both ends are equipped with device parts such as back plate of spring and brake device and are divided into benzo type and split type.

When the axle housing is removed and mounted for maintenance, the axle housing is supported by a jack. At this time, the supporting surface of the jack in contact with the axle housing is generally formed of a flat plate structure.

Figure 1 shows the state of use of the jack when removing and assembling the axle. As can be seen in the drawing, since the rounded surface of the axle assembly 100 is supported by the support plate 210 of the jack 200 having a flat plate structure, the contact area of each other becomes relatively small. Therefore, the axle assembly 100 is not able to be securely fixed by the support plate 210 of the jack is often caused to slip or fall off during operation.

However, such slip and release of the axle assembly 100 has been a problem of causing a safety accident as well as delay of work.

In other words, the conventional axle removal and installation of the vehicle axle using a jack is not easy to reduce the work efficiency, the safety is low, the work environment of the worker is required to improve.

The present invention has been proposed to solve the above problems, and an object of the present invention is to provide an axle detachment jig for a vehicle that can improve work efficiency by increasing work convenience and safety.

According to a feature of the present invention for achieving the above object, the axle detachment jig of the vehicle is a fixed plate formed with a plurality of fastening holes for supporting the lower surface of the axle assembly of the vehicle and fixed to the support plate of the jack, and fixed to the fixed plate T-shaped Three support arms each having a predetermined length drawn out and bent upwards, U-shaped fixing pieces connected to upper ends of both support arms of the three support arms, and integrally at the upper ends of the remaining support arms. A bracket is formed to secure one end of the axle carrier.

In this jig, the fixing pieces are fixed to each other with bolts through fastening holes formed at the same positions as the screw holes at one end of the axle carrier.

In this jig, the fixing piece forms a threaded portion extending at a lower end thereof, and a screw hole to which the screwing portion is fastened at an upper end of each supporting arm so that the supporting arm and the fixing piece are connected to each other.

In this jig, a concave auxiliary support plate having a predetermined size supporting the lower end surface of the axle housing is additionally attached to the center of the fixed plate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments, operations and effects of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 shows the overall configuration of the jig for axle removal according to the invention.

The axle detachable jig includes a fixing plate 10 fixed to the support plate 210 of the jack 200, three support arms 20 connected to the fixing plate, and a fixing piece having a U shape connected to one end of the arm. 30 and the fixing bracket 40.

The fixing plate 10 has a structure in which the fastening hole 11 is formed to be fixed to the support plate 210 of the jack with a bolt. In addition, the three support arms 21, 22, and 23 are fixed to the fixing plate in a “T” shape, respectively, which extend to one side and have a predetermined length vertically bent.

In addition, the fixing piece 30 has a threaded portion 31 formed by extending a lower end thereof with screw holes 21a and 22a at upper ends of the support arms 21 and 22 located at both sides of the three support arms, respectively. To form and bond together.

In addition, the fixing bracket 40 is integrally formed at one end of the other support arm 23, and one end of the carrier 110 of the axle assembly 100 is fixed to the fixing bracket 111 by the fixing bolt 111. 41 has a structure formed.

In addition, a carrier support plate 50 having a concave surface supporting the lower end of the carrier 110 is additionally attached to the central portion of the fixed plate 10.

The jig having the above-described configuration may be used in a state where the fixing piece 30 is separated from the support arm 20 in some cases.

3A and 3B show a state in which the present invention having the above-described structure is mounted and used in a jig.

3A shows the state of use when the entire axle assembly is separated from the vehicle body.

First, the fixing plate 10 of the jig is fixed to the support plate 210 of the jack 200 through a bolt. Then, the jig is positioned at the bottom of the axle to operate the jack 200.

At this time, the shaft axle 101 of both sides is fitted and fixed to the U-shaped fixing piece 30 of the jig, the axle housing 100 is supported by the fixing plate 10, one end of the axle carrier 110 is fixed bracket 40 is fixed by the fixing bolt.

Therefore, since the axle assembly 100 is fixed at three positions by the fixing piece 30 and the fixing bracket 40, the axle assembly 100 can be stably operated without flow.

3B shows the state of use when only the carrier is removed from the axle assembly. The fixing piece of the jig becomes unnecessary, so it is used with it removed.

Referring to the working process, as described in Figure 3A is fixed to the jig to the jack 200 and positioned at the bottom of the axle assembly to operate the jack. Then, one end of the carrier 110 to be separated is fixed to the fixing bracket 40 through the fixing bolt 111, and the carrier support plate 50 is mounted on the bottom surface of the axle carrier 110 to separate the axle carrier. Do the work.

The present invention having the above-described configuration can improve the efficiency of the work by providing the convenience of work by stably fixed by the jack when the axle assembly and the axle carrier for the inspection and repair of the vehicle is separated.

In addition, the present invention has the advantage that the operator can work stably by preventing the slip assembly or slipping is stable in the accelerator assembly or carrier during the operation.
