Wheel hub assembly fixing tool

The present invention relates to a plurality of rim bolts provided on a wheel hub of a vehicle such as a car or a truck. Since the structure of the rim bolt is different from that of a general bolt, it is required to be used with a suitable assembly tool. A fixing tool for fixing the hub before bolting.

Conventional rim bolts are often hex bolts. The hex bolts can be easily disassembled by various hand tools. For the rims and tires fixed by this method, the burglar resistance is low, which may lead to tires and car rims. The high theft rate, and the rim is also easy to loose due to vibration. For this reason, there is a bolt structure specially designed for the rim, which replaces the automobile wheel rim bolts used in the market for the shape of the bolt, and can reduce the car wheel. The ring is lost and prevented from loosening, and can match the bolt structure of a plurality of rims. The rim bolt has a head extending from the head to form a swelling portion, and the expanding portion extends to form a screw, and the screw is different. a locking member; and the diameter of the screw is smaller than the swelling portion, the diameter of the swelling portion is smaller than the head portion; and the swelling portion has a gradually decreasing convex arc shape, and the structural design of the wheel bolt is utilizing the expansion The rising portion can be assembled in an assembly hole of the rim in an urgent manner.

However, the rim bolt is strongly and firmly fixed to the wheel hub. If the vehicle is driven for a long period of time, the rim bolt will inevitably be corroded or deformed. For the safety consideration of the vehicle, the wheel hub rim bolt It must be replaced regularly.

For this reason, the car repair and maintenance industry must disassemble the relevant parts of the entire wheel together with the wheel hub from the wheel axle. This is a labor-intensive and time-consuming operation procedure because the rim bolts are not screwed to the wheel hub. Instead, it is tightly fixed to the wheel hub by compression, and the wheel hub is rotatable. Therefore, if the wheel hub cannot be fixed without rotation, the wheel hub can only be detached from the axle, and the original old bolt can be removed. The hammer is detached from the wheel hub, and the new bolt is rotated in a radial direction by a fastening tool, and the axial tension is gradually tightened onto the wheel hub.

Since the conventional fastening tool is used to tighten the bolt and then apply the force to the bolt in the radial direction, the bolt is axially advanced and assembled to the wheel hub assembly hole. During the rotation, the fastening tool will be combined with the vehicle. The hub faces are pressure-sensitive to each other, which requires the operator to spend more effort to turn the fastening tool, and the conventional wheel must be detached from the body before use. This is because the bolts are removed. When the tool is rotated during the process, since the hub is not fixed, the hub is also rotated when the tool is driven, so that the tool has no force point when it is driven, so the bolt cannot be removed well.

In order to be able to perform the work of tightening the rim bolt with high efficiency, the present invention has developed a fixing tool that can fix the hub, whereby the fixing tool can effectively prevent the hub from being driven to rotate at the same time when the bolt is removed or assembled.
