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

[0046] This embodiment provides a kind of omnidirectional drive wheel device, and this device can drive to any direction, utilizes a driving device to drive driving wheel, thereby makes driven wheel rotate synchronously, (equivalent to utilizing a driving device to drive two wheels at the same time), Compared with the structural form of using two motors to drive a wheel train in the prior art, the control of the device is more convenient than the separate driving of the two motors.

[0047] The specific structure of the omnidirectional drive wheel device provided by the present invention is illustrated below:

[0048] Please refer to Figure 1 to Figure 4 shown;

[0049] The device includes: a fixed base 100 , a driving device 200 , a transmission device 300 , wheels 400 and a steering device 500 .

[0050] The wheel 400 includes a driving wheel 401 and a driven wheel 402 that are rotatably connected to the fixed seat 100;

[0051] The driving device 200 is connected to the...

Embodiment 2

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

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

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

[0087] 1. Through the joint drive of the driving device and the 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 a turning radius of zero.

[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 motor drives two wheels, and the control is more co...

Abstract

The invention relates to the field of logistics transport equipment, in particular to an omni-directional driving wheel device and an AGV (automatic guided vehicle). The omni-directional driving wheel device comprises a fixing seat, a driving device, a transmission actuator, a wheel and a steering device. The wheel comprises a driving wheel and a driven wheel, and the driving wheel and the driven wheel are rotationally connected with the fixing seat; the driving device is in transmission connection with an axle of the driving wheel by the transmission actuator, so that the driving wheel can be driven to rotate; the steering device is mounted on the fixing seat and is connected with the AGV, so that the AGV can omni-directionally move. The AGV comprises the omni-directional driving wheel device. The omni-directional driving wheel device and the AGV have the advantages that the omni-directional driving wheel device is simple in structure and low in cost and control difficulty; the AGV has omni-directional moving functions, and accordingly the production or storage efficiency can be improved.

Description

technical field [0001] The invention relates to the field of logistics handling equipment, in particular to an omnidirectional drive wheel device and an AGV trolley. 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 uses two motors to drive a whee...
