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 mechanical electric hybrid power driven three-wheeled road sweeper which is provided with two power sources of an engine and a storage battery. Under the circumstance of driving a vehicle-mounted working device, the engine further drives a generator to be connected with a drive motor controller, the generator is further connected with the storage battery, the storage battery can be connected with an external charger and connected with the drive motor controller, and the motor controller is connected with a drive motor A to drive the road sweeper to travel at variable speed. Part, of instantaneous generating capacity of the generator, more than requirement of the motor A is used for charging the storage battery, part of the instantaneous generating capacity of the generator, less than the requirement of the motor A is replenished by the storage battery, and the storage battery changes in floating charge and discharge. The three-wheeled road sweeper is small, flexible in steering, high in work capacity, good in dust control effect, more suitable for sweeping bicycle lanes and sidewalks as compared with four-wheeled road sweepers, particularly suitable for sweeping urban roadways, air-conditioned, free of pollution of vehicle exhaust and dust to operators, and capable of working continuously limitlessly as compared with pure electric road sweepers.

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 with dual-engine configurations are commonly used. Such road sweepers are expensive, have high engine power, high fuel consumption, and high operating costs. Driveway and sidewalk cleaning operations cannot enter the urban roadway for cleaning. Even if there are a lot of cleaning on motor vehicle roads, it only needs to be cleaned along the side of the road, and there is no need for a sweeping vehicle with a large cleaning width. There are also small road sweepers that operate and travel with a single engine transmission hydraulic drive, which has low operating efficiency, complicated configuration, and high maintenance costs. There are also miniature three-wheel sweep...
