Single-engine wall surface cleaning vehicle

Abstract

The invention discloses a single-engine wall cleaning vehicle. The single-engine wall cleaning vehicle comprises a chassis, a front cleaning device, a rear cleaning device and a tank body, a gearbox and a main speed reducer are mounted on the chassis; a power take-off mechanism is mounted between the gearbox and the main speed reducer on the chassis; the power take-off mechanism divides the running state of the vehicle into a hydraulic running mode and a mechanical running mode; the hydraulic walking mode is used for adjusting the running speed during vehicle cleaning operation; the mechanical running mode is used for adjusting the running speed of the vehicle during non-cleaning operation. The device can realize stepless speed regulation and low-speed operation, and has good applicability to the working condition of wall cleaning; the whole vehicle can be switched between a hydraulic walking mode and a mechanical walking mode, and the vehicle running performance in a non-operation mode is guaranteed; single-shot driving is achieved, indexes such as noise, oil consumption and emission are excellent, and the maintenance cost is low; and power decoupling and loading function output are stable.

Description

technical field [0001] The patent of the present invention relates to a single-engine wall cleaning vehicle, which belongs to the technical field of municipal cleaning equipment. Background technique [0002] In order to ensure a good cleaning effect, wall cleaning products need to operate at low speed. For areas with heavy wall pollution, the required cleaning speed is slower, and it needs to cover the operating speed range of 0-3km / h. Currently, the mainstream chassis on the market are in the engine economy In the speed range, it is very difficult to reach this speed range. Because they are all mechanical transmissions and the transmission ratio is constant, there will be a speed limit, and stepless speed regulation cannot be performed, and the applicability of the working conditions is not good; and there will be acceleration and deceleration during the operation. , The demand for braking will affect the engine speed, resulting in unstable output of the bodywork function....

Problems solved by technology

[0002] In order to ensure a good cleaning effect, wall cleaning products need to operate at low speed. For areas with heavy wall pollution, the cleaning speed is slower and needs to cover the working speed range of 0-3km / h. At present, the mainstream chassis in the market are economical In the speed range, it is very difficult to reach this speed range. Because they are all mechanical transmissions, the transmission ratio is constant, there will be a speed limit, and stepless speed regulation cannot be performed, and the applicability of the working conditions is not good; and there will be acceleration and deceleration during the operation process. , The demand for braking will affect the engine speed, resulting in unstable output of the bodywork function

Dual engines have an impact on the noise, emissions, and fuel consumption of the vehicle, and increase maintenance costs
