Suspension mechanism, mecanum wheel suspension assembly and mecanum wheel frame vehicle

Abstract

The invention provides a suspension mechanism, a mecanum wheel suspension assembly and a mecanum wheel frame vehicle. The suspension mechanism provided by the present invention comprises a base (1), on which a bearing seat (2) is rotatably connected, and on which a bearing seat (2) is rotatably connected A guide rod (3) arranged horizontally, the guide rod (3) is movably connected on the base (1), a spring (4) is sleeved on the guide rod (3), and the spring ( 4) The two ends are respectively connected with the guide rod (3) and the base (1). The suspension mechanism provided by the invention can reduce the height of the trolley as much as possible, the relative rotation between the bearing seat and the base is possible, and at the same time, the spring can indirectly transmit force and buffer between the bearing seat and the base.

Description

technical field [0001] The invention relates to a suspension and a carriage, in particular to a carriage using a mecanum wheel and its suspension. Background technique [0002] In the process of hoisting, supporting, transshipment, and docking of some products, it is necessary to use a rack. The frame car needs to have sufficient rigidity to ensure that the product can be parked safely and reliably when parked. In addition, in order to transfer products, the truck also needs to have a certain ability to move, especially in the case of a small transfer workshop space, the truck needs to have three degrees of freedom in the plane, that is, without changing its own posture. Under normal circumstances, the trolley can move in any direction in the plane, including forward and backward movement, left and right movement and in-situ rotation movement, that is, it has the ability of "omnidirectional movement". In order to realize the omnidirectional movement of the trolley, there a...

AI Technical Summary

Problems solved by technology

[0004] 1. At present, the main application range of mecanum wheels includes civil forklifts and wheelchairs, which carry small tonnage objects. Due to the limitation of product structure size and load, the existing mecanum wheel frame vehicles do not have the ability to be directly applied to large Conditions in the tonnage support area;

[0005] 2. The existing mecanum wheel frame vehicles generally do not have a suspension system, and the ride comfort is poor. More importantly, since each mecanum wheel cannot be provided with preset thrust to ensure that each wheel is always in contact with the ground, There is a risk of out-of-control movement of the Mecanum wheeled vehicle during climbing and overcoming obstacles;

[0006] 3. In other fields, the current suspension system that uses springs as buffer elements is generally arranged along the height direction. Due to the limitation of vehicle height, and the spring size and stroke are small, it cannot meet the needs of Mecanum wheel frame vehicles. Requirements for adequate ditch and obstacle crossing capabilities under both no-load and full-load conditions
