Description

A heavy-duty truck wheel disassembly tool

technical field

The utility model relates to the field of heavy-duty truck maintenance tools, in particular to a heavy-duty truck wheel disassembly and assembly tool, which is suitable for the disassembly and assembly of heavy-duty truck wheels.

Background technique

For heavy-duty trucks with a wheel rim diameter of more than 20 inches, the removal and installation of the wheel is a frequent operation in the use and maintenance of the vehicle. At present, there is no special tool for disassembly and assembly of heavy-duty truck wheels on the market. The weight and size of heavy-duty truck wheels are relatively large. The traditional disassembly and assembly method is that multiple people use a crowbar to remove or install them from the wheel hub. The operation is time-consuming and labor-intensive, and the technical difficulty is relatively high. In addition, if the operation is improper, there will be accidents in which the wheel falls and the maintenance personnel are injured, and the safety risk is high. In addition, during the disassembly and assembly process, it is necessary to repeatedly use a crowbar to lift and rotate the wheel to adjust the relative position between the wheel screw hole and the hub bolt. Remove or install. This operation will often cause scratches between the wheel screw holes and the hub bolts, damage the threads on the hub bolts, and cause the wheel tightening nuts to not be installed in place, burying hidden dangers for driving safety.

The above-mentioned base includes a lower base and an upper base located above the lower base, the lower base and the upper base are connected by bolts, the lower base is fixed on the bottom plate, and the top of the lower base is provided with a lower base. The base groove is provided with an upper base groove at the bottom of the upper base, and the support beam is clamped between the upper base groove and the lower base groove.

The above-mentioned upper base groove and lower base groove are both arc grooves.

Compared with the prior art, the utility model has the following advantages:

1. The structure is simple, the operation is time-saving and labor-saving and easy to carry.

2. Good safety and easy to use.

3. The work is stable and reliable, and the maintenance rate is low.

Detailed ways

The technical solutions of the present utility model will be described in further detail below with reference to the accompanying drawings.

As shown in Figures 1-3, a heavy truck wheel disassembly tool includes a base plate 4, a plurality of support beams 2 and a plurality of bases 1, each support beam 2 corresponds to two bases 1, and the bases 1 It is arranged on the bottom plate 4 , the two ends of the support beam 2 are respectively fixed on the corresponding two bases 1 by fastening bolts 7 , and a plurality of sliding sleeves 3 are sleeved on the support beam 2 .

The base 1 includes a lower base 5 and an upper base 6 located above the lower base 5, the lower base 5 and the upper base 6 are connected by bolts, the lower base 5 is fixed on the bottom plate 4, and the lower base 5 The bottom of the upper base 6 is provided with a lower base groove, the bottom of the upper base 6 is provided with an upper base groove, and the support beam 2 is clamped between the upper base groove and the lower base groove.

Both the upper base groove and the lower base groove are arc grooves.

In this embodiment, there are two supporting beams 2 , each supporting beam 2 is sleeved with five sliding sleeves 3 , each base 1 corresponds to two fastening bolts 7 , and the lower base 5 is provided with two screw holes , The upper base 6 is provided with two screw holes, and the lower base 5 is welded with the bottom plate 4 as a whole.

First, five sliding sleeves 3 are set on each support beam 2 , and the two ends of the support beam 2 are respectively placed in the lower base grooves on the corresponding lower base 5 . The upper base groove on the upper base 6 is engaged with the support beam 2 , and then the support beam 2 is fastened on the base 1 by two fastening bolts 7 . The inner surfaces of the upper base groove and the lower base groove fit with the support beam 2 , and the sliding sleeve 3 can slide along the axial direction of the support beam 2 , and can also rotate along the radial direction of the support beam 2 .

Before use, apply a small amount of grease on the outer surface of the support beam 2, and slide the sliding sleeve 3 back and forth to spread the grease evenly to further reduce the friction between the sliding sleeve 3 and the support beam 2 during the operation.

When removing the wheel, first gather the five sliding sleeves 3 on each support beam 2 on one end of the supporting beam 2, loosen the wheel tightening nut, lift the wheel to a suitable height with a jack, and concentrate the sliding sleeve 3 on the supporting beam. The end of 2 protrudes under the wheel, while supporting the outer surface of the tire on the sliding sleeve 3. After placing the dismantling tool, you can grab both sides of the wheel and pull the wheel at the end of the support beam without the sliding sleeve. Since the sliding sleeve 3 supports the wheel, and along the axial direction of the support beam 2 with a small friction force moving, the operator can more easily pull the wheel from the hub to complete the removal of the wheel.

When installing the wheels, first concentrate the sliding sleeves 3 on each support beam 2 on one end of the supporting beam 2, and extend the end without the sliding sleeve 3 under the hub, then roll the wheel to be installed on the sliding sleeve 3, and push the wheel. On the outer edge, the sliding sleeve 3 supports the wheel to rotate around the wheel axis, so that the screw holes on the wheel are aligned with the positions of the bolts on the hub. After alignment, push the wheel towards the hub, and the sliding sleeve 3 supports the wheel along the support beam 2. Sliding in the axial direction of the wheel, so that the wheel can be smoothly installed on the hub, and finally the wheel tightening nut can be tightened and the jack can be lowered to complete the installation of the wheel.

When the sliding sleeve 3 or the supporting beam 2 is damaged, the fastening bolts 7 can be unscrewed, the upper base 6 can be removed, and the relevant components can be replaced.

The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or replace them in similar ways, but will not deviate from the spirit of the present invention or go beyond the appended claims the defined range.
