[0003] However, the disadvantages of the Mecanum wheel are also obvious. Due to the existence of small rollers on the edge, the Mecanum wheel has a weak load-bearing capacity and is easy to wear
For the Mecanum wheel mobile platform that requires a large load-bearing capacity, the general solution is to increase the number of wheels. This method can solve the problem of bearing capacity but the problem of wear still exists
Thus affecting the service life of the Mecanum wheel mobile platform

Embodiment Construction
[0017] Describe the present invention below in conjunction with specific embodiment:
[0018] Refer to attached figure 1 , the mobile platform based on air cushion and Mecanum wheel in this embodiment is composed of vehicle frame 1, air cushion unit 2, air spring 3, swing arm suspension 4, Mecanum wheel 5 and electromagnet 6. The overall structure is front-to-back and left-right symmetrical. Refer to attached image 3 Described vehicle frame is divided into front frame 7, middle frame 8 and rear frame 9, and the top of front frame, middle frame and rear frame is connected by upper support plate 10.
[0019] There are four air cushion units 2, which are fixedly connected with the vehicle frame and installed on both sides of the front frame and the bottom of the rear frame of the vehicle frame respectively. The electromagnet 6 is evenly installed on the bottom of the middle frame.
[0020] Between the front frame and the middle frame and between the rear frame and the middle...

Abstract
The invention provide a moving platform based on air cushions and Mecanum wheels, which is composed of a frame, air cushion units, air springs, swing arm type hanger brackets, the Mecanum wheels, and electromagnets, wherein the swing arm type hanger brackets are composed by connecting flanges with swing arms, upper hinges, lower hinges, axles, spring shock absorbers, motors, reductors, and hubs; in the process of moving, the entire moving platform and the load weight of the moving platform are born by the air cushion units, and the Mecanum wheels are only used for driving, and not for bearing load mainly. Therefore, not only the advantages of omnibearing moving and small turning space of the Mecanum wheel can be played, but also the abrasion of the Mecanum wheel can be reduced; the moving platform can suck through the electromagnets at the bottom and steel plates pre-set on the ground after being moved to an assigned position, as a result, the entire platform is fixed, stable, and reliable.
Description
technical field [0001] The invention relates to the application field of omnidirectional wheels, in particular to a mobile platform based on an air cushion and a Mecanum wheel. Background technique [0002] The Mecanum wheel is an omnidirectional four-wheel mobile mechanism. This wheel is made up of two parts, namely the driving hub and a plurality of driven rollers that are evenly distributed in a certain direction along the outer edge of the hub. When the wheel rotates, the speed of the wheel center relative to the ground is the synthesis of the hub speed and the rolling speed of the roller, and there is a deviation angle between the two angles. Because each wheel has this feature, it can realize all-round movement and in-situ steering movement of the car body after being properly combined. Due to the advantages of omnidirectional movement and small steering space, the mobile platform of the Mecanum wheel has been widely used in warehouses, factories and other occasions....
