Problems solved by technology
[0004] However, most of the suspension systems based on Mecanum wheels now have a relatively small buffer stroke. When the chassis of this structure faces some relatively harsh terrains such as steep slopes or steps during operation, it has the ability to absorb shocks. The ability is not good, and the stroke of the shock absorber can easily reach the limit. Therefore, it is imminent to design a Mecanum wheel platform that not only has the function of shock absorption, but also can achieve deceleration with a large deceleration ratio.

The invention discloses a novel Mecanum wheel suspension damping mechanism. The novel Mecanum wheel suspension damping mechanism is composed of a vehicle body mounting plate, a suspension assembly and a chassis. The front portion and the rear portion of the mechanism are each provided with a suspension assembly, each suspension assembly is composed of a shock absorber and two Mecanum wheel sets, and each shock absorber is provided with a buffer spring and installed between a vehicle body installation plate and a chassis. According to the omni-directional mobile platform based on the Mecanum wheels, the pressure can be adjusted according to loads and ground conditions under various different environment working conditions, the influence degree of the ground on the operation process of the Mecanum wheels can be reduced, the phenomenon that a certain wheel set is suspended due to the uneven ground is avoided, The novel Mecanum wheel suspension damping mechanism has the advantages of being stable in operation, high in obstacle crossing capacity and large in bearing capacity.
Description
technical field [0001] The invention relates to the technical field of a Mecanum wheel mobile platform, in particular to a non-independent suspension mechanism of an omnidirectional mobile platform. Background technique [0002] With the development and promotion of robot technology, robots are applied to various environments and terrains, especially some rough terrains. When the robot walks in complex environments and terrains, in order to protect the precision parts and valuable instruments on the robot, it is particularly important for the robot to have a chassis with excellent cushioning effect. [0003] A mecanum wheel is a wheel that moves in all directions based on the principle of a central wheel with many rollers located around the periphery of the hub. These angled peripheral rollers turn a part of the hub The steering force is transformed into a hub normal force; depending on the direction and speed of the respective hubs, these forces eventually produce a result...
