Power driving system of pure electric compression type garbage truck

Abstract

The invention relates to the field of sanitation vehicles, in particular to a power driving system of a pure electric compression type garbage truck. The power driving system mainly refers to a travelling power system and comprises a power battery, a driving motor and a central motor driving axle. A power battery pack is arranged between longitudinal beams, the driving motor is mounted on the central motor driving axle and arranged at the rear end of a truck frame, and the central motor driving axle is a key component of the travelling power system and is also a key component for being distinguished from a traditional speed-changing driving system. The pure electric compression type garbage truck is driven by the driving motor during operation and transition. Through the parallel axis typedirect driving scheme, chassis layout is simpler and tidier, the transmission efficiency is high, the weight is reduced, and the good dynamic property and economical efficiency can be achieved; and the garbage truck mostly works in the wee hours and is charged at night, thus a quite good 'peak load shifting' effect is achieved on a grid system, the stability of the grid system is advantageously maintained, and the using cost is reduced.

Description

technical field [0001] The invention relates to the field of sanitation vehicles, in particular to a power drive system of a pure electric compression garbage truck. Background technique [0002] With the improvement of people's living standards, more and more people begin to pay attention to the transportation and disposal of domestic waste. The compressed garbage truck is a special vehicle for urban sanitation that efficiently collects and transfers garbage. It can avoid secondary pollution caused by leakage along the way during garbage collection and transfer. It is an ideal equipment for urban sanitation work. At present, the compressed garbage trucks used in our country are mainly traditional fuel vehicles, which are noisy, have low engine efficiency, and are prone to exhaust pollution. The environmental sanitation system has more and more expectations for compressed garbage trucks, and has higher expectations for the performance characteristics of compressed garbage t...

AI Technical Summary

Problems solved by technology

However, during the transfer process of the garbage truck, the driving speed of the vehicle is mostly around 40km / h, the driving speed is low, and the speed variation range is small, the driving motor load is small, the efficiency is low, and the utilization rate of the gearbox is not high, resulting in economic Poor performance and high failure rate
