Abstract

The invention provides a Mecanum wheel multi-rigidity spring suspension for a heavy-load omnidirectional mobile platform. The suspension comprises a first A-type spring assembly and a second A-type spring assembly with the same structure, and is characterized in that the first A-type spring assembly comprises an upper-layer spring, a lower-layer spring, a vibration isolation block and an A-type guide column; a transverse plate of the vehicle body connecting support is connected to the upper surface of the bottom of a first mounting groove of the vibration isolation block through the upper-layer spring, the lower surface of the bottom of the first mounting groove of the vibration isolation block is connected to a first suspension mounting base through the lower-layer spring, and the A-shaped guide column sequentially penetrates through the transverse plate, the upper-layer spring, the first mounting groove, the lower-layer spring and the first suspension mounting base. The top end of the A-shaped guide column is fixedly connected to the transverse plate through an upper adjusting nut, the bottom end of the A-shaped guide column is fixedly connected to the first suspension mounting base through a lower adjusting nut, and the vibration isolation block can move up and down between the transverse plate and the first suspension mounting base. Vibration generated by the ground is transmitted to the heavy-load omni-directional moving platform through the A-type spring assembly, and finally the vibration is small.

Description

technical field

[0001] The invention belongs to the field of AGV heavy-duty mobile platforms, in particular to a Mecanum wheel multi-stiffness spring suspension for heavy-duty omnidirectional mobile platforms. Background technique

[0002] In the field of heavy-duty omnidirectional mobile platforms, omnidirectional wheels represented by mecanum wheels are widely used due to their variety and flexibility of motion. During the use of the heavy-duty omnidirectional mobile platform, the vibration of the Mecanum wheel caused by the impact of the ground will affect the stability of the heavy-duty omnidirectional mobile platform, which in turn will affect the use of the heavy-duty omnidirectional mobile platform and reduce the impact of the heavy-duty omnidirectional mobile platform. Therefore, it is necessary to ensure the stability of the heavy-duty omnidirectional mobile platform and reduce the vibration of the omnidirectional mobile platform during use; this puts higher require...
