Loading and traveling hybrid driving sanitation work vehicle and control method thereof

Abstract

The invention discloses a loading and traveling hybrid driving sanitation work vehicle, which includes an engine, a driving axle, an electric generator, a first empty sleeve gear, a first connection sleeve, a loading motor, a battery, a planetary gear deceleration mechanism, a second spline hub, a second empty sleeve gear, and a second connection sleeve. The engine is provided with an output shaft, and a gear is fixed to the output shaft; the driving axle is connected with the output shaft, and the two ends of the driving axle are connected with driving wheels; the electric generator is provided with a transmission shaft, and the first spline hub is coaxially fixed to the transmission shaft; the first empty sleeve gear sleeves the transmission shaft and is engaged with the gear; the first empty sleeve gear is internally and fixedly provided with a first connection outer gear ring; and the first connection sleeve is slidably connected with the first spline hub; the loading motor is connected with the electric generator; the battery is connected with the loading motor; the input end of the planetary gear deceleration mechanism is fixedly connected with the output end of the loading motor, and the planetary gear deceleration mechanism includes a planetary frame gear; the second spline hub is fixed to the middle of the output shaft; the second empty sleeve gear sleeves the output shaft and is engaged with the planetary frame gear; the second empty sleeve gear is internally and fixedly provided with a second outer gear ring; and the second connection sleeve is slidably connected with the second spline hub.

Description

technical field [0001] The invention relates to the field of hybrid electric vehicles, in particular to a top-loading and walking hybrid drive sanitation work vehicle and a control method thereof. Background technique [0002] In recent years, with the increasingly serious energy and environmental problems, energy conservation and environmental protection have become a major theme of today's development. The automobile industry is also gradually developing in the direction of energy conservation and environmental protection. Various new energy vehicles have emerged as the times require. The emergence of new technologies such as pure electric vehicles, hybrid vehicles, and fuel cell vehicles has accelerated the transformation and upgrading of automobile energy utilization. Among them, hybrid vehicles have won the favor of various automobile manufacturers and consumers due to their relatively mature technology, convenient energy acquisition methods and driving range comparable...

Problems solved by technology

D-zero is a pure electric sanitation work vehicle with the advantages of zero operation difficulty, convenient charging, zero emission and low noise, which can greatly reduce exhaust emissions and reduce air pollution. However, this work vehicle is a small sanitation work vehicle with limited cleaning capacity , and the pure electric drive mode has high requirements on battery performance, but the current problem of battery energy density has not been well resolved, making it difficult to apply this pure electric drive mode to medium and large sanitation work vehicles
