Oil-electric hybrid power road sweeper

Abstract

The invention provides a novel oil-electric hybrid power road sweeper which comprises a motor vehicle, a sweeping device and a garbage box; the motor vehicle is mainly provided with a secondary chassis with a non-power taking window gearbox, an engine and a generator arranged at the lower left part of the front end; a crankshaft pulley on the front end of the engine uses two V belts to drive a generator belt pulley; the configuration requirements of the generator are as follows: 28V, 100A DC generator, and about 2000r / min rotating speed; the sweeping device mainly comprises a double-rotating brush, a side brush, a hydraulic power unit and all oil cylinders controlled by the same and all working motors; the whole sweeping device is in electric transmission, and each motor is connected with the generator through a single circuit; and the garbage box and the sweeping device are arranged on the motor vehicle. The oil-electric hybrid power road sweeper solves an oil-electric hybrid power model which not only adopts the single engine but also adopts an electric driving system to drag a sweeping operation system.

Description

technical field [0001] The invention relates to a road cleaning tool, in particular to a road cleaning vehicle. Background technique [0002] As one of the sanitation equipment, the road sweeper is a new type of efficient cleaning equipment that integrates road cleaning, garbage, recycling and transportation. [0003] At present, the existing small and medium-sized road sweepers in China can be roughly divided into three categories in terms of structural form and power configuration: one is to use the existing second-class chassis, and the walking part uses its own equipped engine to complete the walking during work, The cleaning part must be equipped with an auxiliary engine, that is, a double-engine structure with complex structure, low power utilization rate and high fuel consumption; the second type is to use the existing second-class chassis, and the travel gearbox must have a special ultra-low gear and power take-off window to complete the power configuration of the c...

Problems solved by technology

[0003] At present, the existing small and medium-sized road sweepers in China can be roughly divided into three categories in terms of structural form and power configuration: one is to use the existing second-class chassis, and the walking part uses its own equipped engine to complete the walking during work, The cleaning part must be equipped with an auxiliary engine, that is, a double-engine structure with complex structure, low power utilization rate and high fuel consumption; the second type is to use the existing second-class chassis, and the travel gearbox must have a special ultra-low gear and power take-off window to complete the power configuration of the cleaning work, but the gearboxes of the existing small second-class chassis in the market do not have a power take-off window, which brings great difficulties to the design of a single-engine road sweeper; the third category is The all-electric small road sweeper is characterized by using a large-capacity battery for power supply, and the battery itself is too large. Generally, a 48V, 280AH lead-acid battery weighs about 500KG, which is too heavy. If a lithium battery is used, the battery cost will increase by more than ten times, it is obviously unbearable for users

Therefore, although the pure electric road sweeper has the advantages of environmental protection, convenient operation, and simple transmission system, its disadvantages are very obvious.
