Problems solved by technology

[0004] The existing mecanum wheel can realize omnidirectional movement, but the cost is high and the load is low
The differential wheel set uses two motors to drive a wheel train, and realizes the steering of the wheel train through the different speeds of the two wheels. Its advantages are large load capacity and high efficiency. When adjusting the direction during the process, the control difficulty increases

Embodiment 1

[0047] See figure 1 ; The present embodiment provides an omnidirectional differential drive wheel device, which can travel in any direction, and utilizes one driving device 200 to simultaneously drive two wheels 400, compared with the prior art that utilizes two motors to drive a wheel train In terms of structural form, the control of this device is more convenient than the separate driving of two motors; and the speed of the two wheels 400 is automatically distributed by the differential 300, and the steering is more stable and the steering control is more convenient.

[0048] The specific structure of the omnidirectional differential drive wheel device provided by the present invention is illustrated below:

[0049] Please refer to Figure 1 to Figure 4 shown;

[0050] The device includes: a fixed base 100 , a driving device 200 , a differential 300 , wheels 400 and a steering device 500 .

[0051] The driving device 200 is in transmission connection with the differential...

Embodiment 2

[0084] Please refer to Figure 4 , The purpose of this embodiment is to provide an AGV trolley, including the omnidirectional differential drive wheel device as described above.

[0085] During specific setting, a plurality of above-mentioned omnidirectional differential drive wheel devices can be set at the bottom of the AGV trolley.

[0086] The AGV trolley using the above-mentioned omnidirectional differential drive wheel device has the following advantages:

[0087] 1. Through the joint drive of the drive device, differential gear and steering device, the AGV trolley can be turned freely in 360 degrees, and at the same time, it can realize the in-situ steering with zero turning radius.

[0088] 2. Each wheel train has two wheels landing on the ground at the same time, which improves the carrying capacity of the AGV trolley;

[0089] 3. The steering motor precisely controls the direction of the wheels, and the AGV trolley has small driving deviation;

[0090] 4. One moto...

Abstract

The invention relates to the field of logistic haulage equipment, in particular to an omni-directional differential drive wheel device and an AGV using the omni-directional differential drive wheel device. The device comprises a fixing seat, a drive device, a differential mechanism, wheels and a steering device. The differential mechanism is installed on the fixing seat, and the two output ends of the differential mechanism are connected with the wheels through an axle. The drive device is connected with the differential mechanism so as to supply power. The steering device is installed on the fixing seat, meanwhile, the steering device is connected with the AGV, and therefore omni-directional motion of the AGV is achieved. The omni-directional differential drive wheel device has the beneficial effects of being simple in structure, low in cost and low in control difficulty. The AGV comprises the above omni-directional differential drive wheel device and has the omni-directional motion function, and production or storage efficiency can be improved.

Description

technical field [0001] The invention relates to the field of material handling equipment, in particular to an omnidirectional differential drive wheel device and an AGV trolley using the device. Background technique [0002] The AGV trolley is a transport vehicle that can drive along the specified guiding path and has safety protection and various transfer functions. Due to its high degree of automation, safety, and flexibility, it is currently the best for automatic material handling in China. One of the solutions. [0003] At present, many production workshops or warehouses use AGV trolleys to transport items to improve the efficiency of production or storage. Due to the limitation of the site, the AGV car needs to have the function of omnidirectional movement, that is, turning in place and driving in any direction. [0004] The existing mecanum wheel can realize omnidirectional movement, but the cost is relatively high and the load is low. The differential wheel set us...
