Abstract

The invention discloses a vertical differential drive assembly, which includes an assembly support, a slewing support is arranged at intervals under the assembly support, and a differential drive device is connected to the lower end of the inner ring of the slewing support. A navigation induction device is installed on the slewing support, and a slewing support seat is fixedly connected to the outer ring of the slewing support. A single-turn absolute value encoder is arranged on the slewing support seat. The axis of the single-turn absolute value encoder and the rotary shaft of the slewing support The centers are on the same vertical line, an encoder shaft pin assembly is connected to the inner ring of the slewing support, a driving and lifting device is provided on the assembly support, and multiple shafts are installed between the assembly support and the slewing support A rectangular spring, the invention facilitates the navigation sensor assembly to be arranged on the symmetrical line of the drive assembly, and also has a driving lifting device, which is convenient for the forklift to change the work site, and the encoder shaft pin assembly adopts an elastic coupling and an expansion rubber sleeve. The combined structure reduces the induction error of the encoder to the rotation angle.

Description

technical field [0001] The invention belongs to the field of AGV trolleys, in particular to a vertical differential drive assembly. Background technique [0002] AGV forklifts are equipped with electromagnetic or laser or other conductive induction devices, which can automatically drive, turn and stop along the set path. It is widely used in various automated production lines and warehouses, which can greatly improve the transportation efficiency of factories and warehouses. [0003] In the existing stacker forklifts, the vertical steering wheel is generally used as the drive unit. The magnetic strip cannot be laid from the center line of the forklift, which is not conducive to the layout of the magnetic navigation sensor. It is convenient for the forklift to change the work site. Encoders are generally provided in AGV forklifts, so it is also necessary to provide an encoder shaft pin assembly that can reduce the induced angle error. Contents of the invention [0004] In...
