Problems solved by technology

[0002] The suspension structure of the existing AGV (Automated Guided Vehicle) trolley often adopts a cross-bar suspension system or a linear bearing suspension system, which has the following disadvantages: (1) the structure is not compact enough and takes up a lot of space; (2) the cross-bar structure The processing accuracy of the cross rod is high and the cost is high; (3) the cross rod and linear bearing suspension system are prone to run unsmoothly during use, which leads to insufficient adhesion of the driving wheel and poor stability of the trolley on the other hand Unsmooth operation also leads to faster wear of the suspension system, thereby reducing the life of the entire suspension system; (4) The cross-bar structure and the linear bearing structure have low load-carrying capacity

no. 1 example

[0027] This embodiment provides a driving wheel suspension damping mechanism 1 for an AGV, see the attached Figure 1-7 , the suspension damping mechanism 1 includes, guide rail fixing plate 4, slider fixing plate 5, linear guide rail 6, slider 7, slider limit mechanism, guide rod 10, guide rod fixing mechanism, spring, spring fixing device, Spring limit device.

[0028] The guide rail fixing plate 4 is arranged on the chassis P, and it includes two vertical guide rail fixing part plates and a first connecting part plate connecting the two guide rail fixing part plates, and the two guide rail fixing part plates are connected with the first guide rail fixing part plates. The connecting part board is vertical, and the linear guide rail 6 is arranged on the guide rail fixing part board on the guide rail fixing board 4 along the vertical direction; the slider fixing board 5 is arranged on the chassis P, which includes two vertical The slider fixed part plate is connected with the...

no. 2 example

[0040] This embodiment provides a driving wheel suspension damping mechanism for an AGV trolley. On the basis of the first embodiment, the side of the slider fixing plate 5 of the suspension damping mechanism 1 near the spring 13 is equipped with multiple Sensor 25, a plurality of sensors 25 are arranged along the vertical direction, and are used to detect the compression and / or elongation of rectangular spring 13, the relative displacement of linear guide rail 6 and slide block 7, the vibration damping mounting plate 23 and the servo motor 2. One / multiple sensors 26 are arranged on the groove surface of the opposite side. The sensors 26 are used to detect the relative position of the servo motor 2 and the suspension damping mounting plate 23, and compare it with the preset value, so as to judge the suspension damping The state of the mechanism, such as whether there is an error, whether there is a fault, whether it is damaged, etc.

[0041] It also includes a controller, whic...

Abstract

The invention discloses a driving wheel suspension damping mechanism for an AGV. The upper surface of a suspension damping mounting plate is fixedly connected with a sliding block fixing plate, and aplurality of sliding blocks are mounted on the side, close to a driving wheel, of the sliding block fixing plate. The suspension damping mounting plate is provided with two guide rods, and each of theguide rods is provided with a locknut, a first spring limiting pad, a rectangular spring, a second spring limiting pad and a spring fixing seat from top to bottom. A suspension structure adopts a structure of which a linear guide rail is matched with damping springs, the structure is simple and compact, the operation is smooth, the shock absorption effect is good, the bearing capacity is high, the adhesive force provided to the drive wheel is large, and the adaptability to a complex road surface is good.

Description
