Cleaning car single-engine system and cleaning car thereof

Abstract

The invention discloses a cleaning car single-engine system and a cleaning car thereof. The cleaning car single-engine system comprises an engine, a generator, an AC/DC controller, a DC/AC controller, an upper loading controller, a driving motor, a clutch and a transmission; the generator and the clutch coat an output shaft of the engine in sequence; the engine drives the generator to generate electricity; the output shaft of the engine is connected with the transmission through the clutch; an output end of the generator is connected with the AC/DC controller; the AC/DC controller is connected with the DC/AC controller through a direct-current high-voltage wire; an output end of the DC/AC controller is connected with the driving motor through a three-phase wire; an output end of the driving motor is connected with loading equipment; and the upper loading controller is respectively connected with the AC/DC controller and the DC/AC controller through CAN buses. The invention adopts the single-engine system, so that the whole car oil consumption is reduced, and the emission is reduced; and an upper loading system has a relatively independent and stable power source, so that the safety is high.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a single-engine system of a sweeper and the sweeper. Background technique [0002] Urban road cleaning vehicles, including road sweepers, vacuum cleaners, cleaning vehicles and sweeping vehicles, generally use the main engine and the auxiliary engine to provide power for the chassis driving and the upper loading working device respectively. The main engine is used to drive the whole vehicle, which requires a lot of power. However, since the cleaning and cleaning vehicles generally operate at a speed below 20km / h, they work at low speed for a long time, resulting in low work efficiency. Coupled with the simultaneous operation of the auxiliary engines, it is difficult to effectively control the emission and noise of the whole vehicle, and the energy consumption efficiency of the whole vehicle is low. [0003] As the country's emission requirements for sanitation vehicles become ...

Problems solved by technology

[0005] Another solution such as the patent "CN 105291828 A A single engine system for an environmentally friendly car" is that the engine is connected to the power take-off device and then connected to the gearbox and the generator, and the generator drives the special device. The disadvantage of this solution is that the gearbox It is arranged in parallel with the generator. The power output end of the generator driven by the engine also needs to have a transfer device, and a power take-off device is added between the clutch and the engine. The performance of the whole vehicle is easily affected by the performance of the power take-off device, and the layout structure is complicated.

In addition, the system also adds a battery, which takes up a lot of space, which is contrary to the lightweight design of the whole vehicle. The system of the whole vehicle is complicated, and it also has the normal high voltage of the battery even when the whole vehicle is not working, so it is safe and reliable. Greatly reduced
