Driving system of battery transport car

Abstract

The invention relates to a driving system of a battery transport car, wherein a direct current motor and a gear box are fixed together; a fixed big internal gear ring is arranged in the gear box; a sun gear is arranged on a direct current motor shaft; an output shaft is fixed on the gear box right opposite the sun gear by a bearing; a planetary gear carrier is fixed at the end of the output shaft in the gear box; two or three same planetary gears are uniformly arranged on the planetary gear carrier; the planetary gears are meshed with a fixed big internal gear and the sun gear in the meantime; a differential mechanism is arranged in the middle of a rear axle; a power input end of the differential mechanism and the output shaft are connected by utilizing a cardan joint; two sides of the real axle are respectively provided with a half axle; and driving wheels are fixed on the half-axle ends. The driving system disclosed by the invention has the advantages that a better shock-absorbing effect is provided and the service life can be prolonged.

Description

Technical field [0001] The invention relates to a battery transport vehicle, in particular to a drive system of a battery transport vehicle, and belongs to the technical field of battery transport vehicles. Background technique [0002] In the process of cargo transfer inside the factory, most of the battery transport vehicles are used. The drive system of the existing battery transport vehicles generally includes an electric motor, a gear box, a differential, a rear axle, left and right half shafts and driving wheels. Above, the gearbox and the rear axle are connected and fixed as a whole, the motor and the gearbox are installed and fixed together, and the motor shaft, the input and output shafts of the gearbox and the left and right half shafts in the rear axle are installed in parallel. This structure Although the drive system of the battery transporter has the advantages of compact structure, because the entire transmission system is rigidly installed and fixed together with ...

AI Technical Summary

Problems solved by technology

[0002] In the process of cargo transfer inside the factory, battery transport vehicles are mostly used. The drive system of existing battery transport vehicles generally includes electric motors, gearboxes, differentials, rear axles, left and right axle shafts, and driving wheels. Above, the gearbox and the rear axle are connected and fixed as a whole, the motor and the gearbox are installed and fixed together, and the motor shaft, the input and output shafts of the gearbox, and the left and right half shafts of the rear axle are installed in a parallel state. This structure Although the drive system of the battery transport vehicle has the advantage of compact structure, since the entire transmission system and the rear axle are rigidly installed and fixed together, the motor of the transmission system and the gearbox are subject to vibrations during the driving of the vehicle. It is also relatively large, which will reduce the service life of the motor and the gearbox, and even damage the corresponding parts in severe cases.
