Dynamic drive pallet truck and dynamic drive wheel thereof

Abstract

The invention discloses a dynamic drive pallet truck and a dynamic drive wheel thereof. The dynamic drive pallet truck comprises a truck body, a drive wheel assembly installed on the bottom surface of the truck body and an electric control system, wherein the drive wheel assembly comprises a drive motor, a shell, drive wheels, a driven shaft, a speed reduction gear set and an electromagnetic brake, the speed reduction gear set comprises a first driving gear, a driven gear and a second driving gear, each drive wheel comprises an installation ring, a hub ring and an outer tire ring, the installation ring, the hub ring and the outer tire ring of each drive wheel are sequentially arranged from inside to outside, the first driving gear is fixed to an output shaft of the drive motor, the driven gear and the second driving gear are fixed to the driven shaft, the first driving gear is meshed with the driven gear, each installation ring is provided with an inner gear ring, the second driving gear is meshed with the inner gear rings, and the electromagnetic brake is installed on the end portion of the output shaft of the drive motor. The structural design of the drive wheels is simplified, the size is compact, manufacturing cost is reduced, and transmission efficiency and the brake effect are improved. .

Description

technical field [0001] The invention relates to a loading and unloading vehicle and its parts, in particular to an electric-driven pallet truck and its electric driving wheels. Background technique [0002] The movement of the existing electric pallet truck is realized by the driving wheels installed on the chassis of the pallet truck, and the driving wheels are mostly driven by electric motors. Since the electric pallet truck needs to be frequently started and decelerated during operation, the activation of the driving wheels Both the speed and the braking requirements are relatively high, the driving structure of the existing driving wheel is bulky, the work efficiency is low, and the structure of the braking system is complex and the braking effect is poor. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies existing in the prior art, and provide a kind of electric drive pallet truck and its electric dr...
