Washing and sweeping vehicle provided with single motor drive mechanism

Abstract

The invention discloses a washing and sweeping vehicle provided with a single motor drive mechanism. The washing and sweeping vehicle comprises a suction fan, a suction air duct, a suction tube, a suction disc, an air brush disc, a high-pressure water pump, a sewage tank, a clear water tank, a water spraying device and the single motor drive mechanism. The single motor drive mechanism comprises an automobile chassis, an engine, a transmission shaft and a rear axle. The washing and sweeping vehicle is characterized in that the single engine is adopted for the single motor drive mechanism, the engine is connected with a full-power power take-off device, the full-power power take-off device is connected with a clutch through the transmission shaft, the clutch is connected with a gear case, an output shaft of the gear case is connected with driving auxiliary equipment, the full-power power take-off device is further connected with a gearbox, and the gearbox drives the rear axle through the power transmission shaft. By means of the washing and sweeping vehicle, the engine can drive work components of a sanitation truck steadily in any speed ranges, and normal driving of the vehicle is not affected, so that an existing sanitation truck can still work normally without installing an auxiliary engine, the acquisition cost of the auxiliary engine is omitted, use cost can be further saved, and emission of tail gas is lowered.

Description

technical field [0001] The invention belongs to the technical field of special drive systems for sanitation vehicles, and in particular relates to a sweeping vehicle with a single-engine drive mechanism. Background technique [0002] With the widespread application of sanitation vehicles, how to improve the efficiency of sanitation vehicles, reduce vehicle purchase costs and exhaust emissions has become a new research topic. Since the sanitation vehicle requires the fan to have a higher speed and a lower vehicle speed during work, the conventional sanitation vehicles currently on the market basically use dual engines, the chassis engine mainly drives the vehicle, and the auxiliary engine mainly drives the fan. The movement of working parts such as water pumps. The sanitation vehicle with a single engine can use one engine to drive the driving of the vehicle and the movement of the working parts at the same time, so that the sanitation vehicle can meet the high-speed rotatio...

AI Technical Summary

Problems solved by technology

The disadvantage of this power take-off method is that when the chassis main clutch and / or gearbox are operated, it will cause changes in the power take-off speed and torque, change the power matching point of the working device, and thus affect the working performance of the working device

The patent CN201410284875.3 discloses another single-engine sweeper, which mainly uses a transfer case to realize the stable driving of the operating mechanism under different driving conditions. The use of the transfer case will greatly increase the cost of the sweeper, and the structure is complicated , easily damaged, not easy to repair
