A novel transmission and suspension system and a 500 kG-loaded compact AGV (automatic guided vehicle) thereof

Abstract

A novel transmission and suspension system comprises driving devices and a suspension device; the two same driving devices are hinged to the suspension device; the driving device comprises a direct-current servo motor, a planetary reducer, a gear box and a driving wheel; the suspension device comprises a rectangular spring, a large adjusting nut and a spring guide shaft. The direct-current servo motors in the two sets of the same driving devices are connected with driving wheels through gearboxes respectively, so that the positions of the two differential driving wheels, which are staggered from the planetary reducer through the gearboxes, are formed; the spring guide shaft penetrates through a waist-shaped hole in the left end of the gear box, and the rectangular spring penetrates throughthe spring guide shaft and is arranged between the adjusting large nut and the gear box. In addition, the invention further discloses a 500 KG-loaded compact AGV.

Description

technical field [0001] The invention relates to a transmission and suspension system, in particular to a novel transmission and suspension system and a compact AGV (Automatic Guided Vehicle) transport vehicle with a load of 500KG, belonging to the field of mechanical structures. Background technique [0002] The driving part of the transmission and suspension system in the prior art is directly connected to the drive wheel through the motor connected to the reducer through the pin shaft; the suspension part: the suspension is composed of two sets of guide shafts, two shaft end fixing seats and oil-free bushings symmetrically arranged. Guide, two groups of springs and guide shafts are symmetrically arranged to form the shock absorbing part. Its disadvantages: drive part: 1. The width of the trolley is limited because the power parts of the two differential drive wheels cannot be staggered; 2. The direct connection between the reducer and the drive wheel cannot eliminate the c...

AI Technical Summary

Problems solved by technology

Its disadvantages: drive part: 1. The width of the trolley is limited because the power parts of the two differential drive wheels cannot be staggered; 2. The direct connection between the reducer and the drive wheel cannot eliminate the coaxial difference, resulting in serious damage

Suspension part: the two guide shafts require extremely high parallelism, the shaft end fixing seat and the oil-free bushing are precision parts, and the corresponding mounting plate and other parts also need precision machining, so the cost is high

In addition, when the spring reciprocates, the guide part may get stuck, making the shock absorption effect worse
