Description

Technical Field

[0001] The invention relates to the technical field of universal wheels, in particular to a four-bearing silent PU universal wheel. Background Art

[0002] Universal wheels can rotate 360 ​​degrees horizontally and rotate horizontally with the dynamic or static changes of the load. For example, on a trolley or other handling tool, there are usually two fixed wheels at the front and two movable universal wheels at the rear near the push handle, and they have a wide range of applications.

[0003] In the related art, the rolling and 360-degree rotation of the universal wheel are mostly realized by bearings. One bearing ensures the smooth rolling of the universal wheel, and another universal wheel ensures the smooth turning of the universal wheel. When the universal wheel with such a structure is in use, one bearing does not support the universal wheel well, and the parallelism is difficult to ensure. When the universal wheel rolls, the stability and quietness are poor; one bearing realizes the steering of the universal wheel, and there is shaking when the universal wheel turns.

A plug rod is inserted inside the dual-axis stabilizer. A ring groove is provided on the upper surface of the plug rod. A fixing ring is sleeved inside the ring groove. The dual-axis stabilizer has a larger supporting effect and area for the bracket, ensuring that the universal wheel will not shake when turning, and the turning is also quieter; A rivet, the rivet is plugged into the bracket and penetrates the bracket, a double stabilizing sleeve is sleeved on the rivet, and the bracket is sleeved on the surface of the double stabilizing sleeve; A double-axis balancer is sleeved on a surface with a double stabilizing sleeve, and a skateboard wheel is sleeved on the surface of the double-axis balancer. The double-axis balancer has a large supporting area for the skateboard wheel. When the skateboard wheel rolls, the parallelism is better and the rolling noise is low.

[0006] Furthermore, the skateboard wheel is composed of a rim and a PU tire mounted on the surface of the rim. The PU universal wheel can bear a large weight and is suitable for heavy equipment and transportation tools. The PU universal wheel has certain shock absorption and stability and can provide good comfort performance.

[0007] Furthermore, a top cover is sleeved on the upper surface of the bracket, and the top cover seals the dual-axis balancer, shields, decorates and dust-proofs the dual-axis balancer, and ensures smooth sliding of the universal wheel.

[0008] Furthermore, the double stabilizing sleeve includes two through pipes, the cross-section of the through pipes is T-shaped, which prevents rivet wear and provides better support stability for the skateboard wheels.

[0009] Furthermore, the dual-axis stabilizer includes a first bearing and a second bearing, and the first bearing and the second bearing limit the swing of the bracket.

[0010] Furthermore, the dual-axis balancer includes a third bearing and a fourth bearing, and the third bearing and the fourth bearing limit the swing of the skateboard wheels.

[0011] Compared with the prior art, the beneficial effects of the present invention are: the insertion rod is plugged into the first bearing and the second bearing to perform doubly supported and positioned the insertion rod, and the universal wheel is installed on the trolley using the insertion rod to ensure that the insertion rod will not shake and is quieter when turning; the skateboard wheels are assembled through the third bearing and the fourth bearing to achieve parallel support of the skateboard wheels, providing greater support for the skateboard wheels, and the skateboard wheels roll more stably and quietly.
