Embodiment Construction

[0033] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0034] Such as figure 1 , 2 As shown, in this embodiment, a heavy-duty universal wheel according to the present invention includes a wheel bracket 100, a hinge shaft 200 and a roller installation shaft 400 arranged with axes perpendicular to each other but not intersecting, and the roller installation shaft 400 The upper rotatable installation roller 300, the top of the roller installation shaft 400 is provided with a rolling support device, the support center of the rolling support device is fixedly connected with the roller installation shaft 400,

[0035] By setting the rolling support device, the gravity of the heavy load is transmitted to the roller 300 through the rolling support device, so as to avoid increasing the eccentricity between the hinge shaft 200 and the roller installation shaft 4...

Abstract

The invention discloses an overloading universal wheel. The overloading universal wheel comprises a hinged shaft and a rolling wheel mounting shaft. The axis of the hinged shaft and the axis of the rolling wheel mounting shaft are perpendicular to each other but do not cross. A rolling wheel is rotationally arranged on the rolling wheel mounting shaft. A rolling supporting device is arranged above the rolling wheel mounting shaft. The supporting center of the rolling supporting device and the rolling wheel mounting shaft are fixedly connected. By means of the rolling supporting device, gravity for bearing a weight is transmitted to the rolling wheel by virtue of the rolling supporting device, and the situation that in order to improve steering performance, the eccentric distance between the hinged shaft and the rolling wheel mounting shaft is increased, consequently, torque generated by gravity is increased, and the bearing performance and rigidity of the universal wheel are influenced is avoided.

Description

technical field [0001] The invention relates to the technical field of transportation equipment manufacturing, in particular to a universal wheel with large carrying capacity and flexible steering, and in particular to a heavy-duty universal wheel. Background technique [0002] Casters include movable casters and fixed casters. Swivel casters are what we call universal wheels, and its structure allows 360-degree rotation; fixed casters are also called directional casters, which have no rotating structure and cannot be rotated. Due to the characteristics of convenient steering, universal wheels are widely used in industrial production and daily life. [0003] The supporting structure of the swivel caster in the prior art is complicated, the manufacturing process is many, and in order not to affect the flexibility of its steering, the load bearing and impact resistance are limited. The steering performance of the swivel caster depends on the eccentricity between the rotating s...
