Description

Technical Field

[0001] The utility model relates to the technical field of Mecanum wheel installation, and more specifically, to a Mecanum wheel suspension structure. Background Art

[0002] The Mecanum wheel is an omnidirectional wheel. The most obvious feature of this wheel is that a number of free rollers are installed on the outer edge of the hub in a direction at a certain angle to the wheel axis. When the wheel revolves in a direction perpendicular to the wheel axis, the rollers rotate along the axis of the roller shaft to produce lateral movement. Therefore, the Mecanum wheel can achieve omnidirectional movement.

[0003] When the Mecanum wheel is in use, it needs to be installed at the bottom of the vehicle body through the suspension. The suspension includes two integrally formed support plates arranged on both sides of the Mecanum wheel. The Mecanum wheel is installed between the two support plates through the shaft and the bearing. When the Mecanum wheel needs to be replaced or repaired, the suspension needs to be disassembled as a whole so that the two support plates can be separated from each other before the Mecanum wheel can be disassembled, which makes the disassembly operation cumbersome and inconvenient.
