Problems solved by technology

Pure electric vehicle technology is not suitable for road sweepers. Road sweepers need not only variable power to drive the vehicle to drive at variable speeds, but also stable power to drive the on-board operating devices to work stably; generally, they must be able to operate in double shifts. Due to weather or road pollution, it is even necessary to be able to meet temporary arrangements for overtime work; the battery of a pure electric road sweeper is high in manufacturing cost, heavy in weight, and occupies a large space in a special vehicle. The battery is too heavy to consume energy when driving. The relatively long charging time cannot meet the uncertain continuous operation time requirements, and it is impossible to install air conditioners to ensure operating comfort and avoid drivers from being polluted by vehicle exhaust and cleaning dust on the road, lacking the motivation to guarantee humanized design

Abstract

The invention provides a three-wheel road sweeper driven by mechanical and electric hybrid power. The road sweeper is provided with two power sources, namely an engine and a storage battery; under the condition that a vehicle-mounted working device is driven to work stably, the engine also drives a generator and is connected with a motor A through a motor controller to drive the road sweeper to run at variable speed; the generator is simultaneously connected with the storage battery; the storage battery is also connected with the motor A through the motor controller; the part of the instantaneous power generation quantity of the generator, which is greater than the demand of the motor A, charges the storage battery; the part of the instantaneous power generation quantity of the generator, which is smaller than the demand of the motor A, is supplied by the storage battery; and the storage battery alternates charge and discharge. The road sweeper is small, flexible in turning, strong in working capability and good in dust control effect; compared with a four-wheel road sweeper, the invention has the advantages that the three-wheel road sweeper is suitable for sweeping bicycle lanes and sidewalks and is particularly suitable for sweeping urban laneways; compared with a micro road sweeper, the invention has the advantages that the three-wheel road sweeper is strong in working capability, and an operator is not subjected to pollution of automobile exhaust and dust due to an air conditioner; and compared with a pure electric road sweeper, the invention has the advantages that the three-wheel road sweeper can unlimitedly and continuously work.

Description

technical field [0001] The invention relates to a road sweeper, in particular to a three-wheeled road sweeper. Background technique [0002] The city has popularized the use of road sweepers to clean the roads, but there are deficiencies in the prior art. At present, medium-sized or large-scale road sweepers are commonly used. Such road sweepers are expensive, have high engine power, high fuel consumption, and high operating costs. Especially, four-wheel road sweepers with such a width cannot clean bicycle lanes and sidewalks. It is impossible to enter the urban roadway for cleaning, and many motor vehicle lanes only need to be cleaned on the side of the road, and do not need a large cleaning width. There are also small road sweepers, all of which are four-wheeled and powered by engines. There are also miniature three-wheel sweepers that are only suitable for indoor or courtyard use. When used outdoors, the operating efficiency is low. Basically, the battery is used as the...
