Description

Puller for Automotive Hub

The present invention relates to a puller for an automotive hub, and more particularly, to a puller for an automotive hub, which can be easily detached without damaging or deforming the axle or the hub when separating the hub from the axle of the vehicle.

In general, in order to separate a hub coupled by a bearing to an end of the axle from the axle, when there is no conventional separation device, a large metal tool such as a large gear puller is applied to the hub to remove the hub. While separating the axle and the hub by hitting, but in the case of the method of hitting using a metal tool as described above has a problem such as the injury point of the hub or axle with the disadvantage of being damaged or deformed, the worker is injured.

Therefore, we developed a special tool to separate the axle and the hub safely without damage to the axle and the hub with tools, and such a special tool was developed in Korean Utility Model No. 116834 (announced June 10, 1998). As shown, a vehicle axle removal tool has been developed, which engages a stud bolt on a disc with a long hole into which a stud bolt mounted on a hub is inserted and slides in the center of the intersection by intersecting two frames welded and fixed to the disc. It consists of a boss having a screw hole that is screwed to the thread formed in the hammer. The slider sliding from the slide hammer to the sliding rod is slid to the engaging portion formed at the end of the sliding rod to separate the hub from the axle. However, the impact force is weak when the slider hits the latching part. There was a problem that the hub is not properly separated from the axle.

In addition, the front wheel hub remover of the vehicle, published in Korean Utility Model Model No. 39323 (published on September 15, 1998) in 1998, fixes the hub support plate to the hub, and then attaches a torque pipe to the hub support plate, and then manually It was developed to separate the hub by rotating the extension rod.However, to separate the hub support plate and the axle by rotating the extension rod manually, excessive work force is applied and the workability decreases even when the gloves are worn. The axle hub separating device, which was published in Korean Utility Model No. 108744 (announced on November 3, 1997), had a fixed length of fixed length attached to the piston rod traveling direction of the cylinder, A binding plate having a plurality of coupling holes is formed and connected with a hydraulic pump and a connection hose to separate axles and hubs by hydraulic pressure. It was developed so that the axle and hub could be easily separated, but using only hydraulic pressure, it cost a lot of equipment cost, maintenance cost, and maintenance cost, and it was extremely difficult to equip small maintenance companies due to the increase in manufacturing cost of the device. Since the prior arts all have different dimensions and shapes of axles and hubs according to various vehicle types, they must have a plurality of vehicles according to various vehicle types, and thus have a number of problems such as difficulty in providing a small-scale business because purchase cost increases. .
