Problems solved by technology
[0002] In the past, the two wheels of the differential drive of the AGV trolley were connected by a shock absorber. This structure made the two wheels lie in the same axial direction. , will drive the other wheel to be in a tilted state, the contact area with the ground will become smaller, and the running stability will also be reduced, especially during the turning process, the speed of the two wheels is different, if one of the wheels encounters bumps, And the other wheel is also tilted and the contact area with the bottom surface is reduced, the accuracy of the controlled turning angle will be reduced, so it needs to be improved

The invention provides a differential driver of an AGV. The differential driver comprises a mounting frame, a rotary supporting bearing, an angle sensor and two groups of wheel assemblies, wherein therotary supporting bearing, the angle sensor and the two groups of wheel assemblies are mounted on the mounting frame; the angle sensor is located beside the rotary supporting bearing, and a rotatingshaft is installed at the rear side of the mounting frame; the two wheel assemblies are the same in structure and are installed at the left side and the right side of the mounting frame correspondingly; each wheel assembly comprises a connecting frame, a driving device, a speed reducing device, a damping device and wheels, wherein the rear side of the connecting frame is hinged with the rotating shaft, the front side of the connecting frame is connected with the mounting frame through the damping device, the driving device is mounted on the connecting frame and is positioned at the side closeto the mounting frame, the wheels are installed on the connecting frame and located at the side away from the mounting frame, and the driving device drives the wheels to rotate through the speed reducing device. The differential driver is higher in working stability and is convenient to mount and dismount.
Description
technical field [0001] The invention relates to the technical field of AGV trolleys, in particular to a differential drive for AGV trolleys. Background technique [0002] In the past, the two wheels of the differential drive of the AGV trolley were connected by a shock absorber. This structure made the two wheels lie in the same axial direction. , will drive the other wheel to be in a tilted state, the contact area with the ground will become smaller, and the running stability will also be reduced, especially during the turning process, the speed of the two wheels is different, if one of the wheels encounters bumps, And another wheel is also tilted and the area of contact with the bottom surface decreases, then the precision of the turning angle of control will reduce, so it needs to be improved. Contents of the invention [0003] The purpose of the present invention is to provide a differential drive of an AGV trolley to solve the problems mentioned in the background t...
