Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] A power system for a sanitation vehicle, including a driving power system and a vehicle-mounted operating device. The driving power system is a fuel-hydraulic hybrid power system. The driving power system includes a hydraulic motor connected with a mechanical transmission of the vehicle-mounted operating device. The hydraulic accumulator is connected to the hydraulic transmission.

[0033] A sanitation vehicle power control method based on the power system of the above-mentioned sanitation vehicle, at least including the operation of the vehicle-mounted operation device: when the energy of the hydraulic accumulator is greater than the energy required by the vehicle-mounted operation device, the hydraulic accumulator provides the vehicle-mounted operation device with Energy; when the energy of the hydraulic accumulator is less than the energy required b...

Abstract

The invention relates to a power system and a power control method of a sanitation vehicle. The power system comprises a travelling crane power system and a vehicle-mounted operation device, wherein the travelling crane power system is a fuel hydraulic hybrid power system and comprises a hydraulic motor connected with the vehicle-mounted operation device in a mechanical driving way; the hydraulic motor is connected with a hydraulic energy-storing device in the travelling crane power system in a hydraulic driving way. The control method comprises the steps of according to the energy of the hydraulic energy-storing device, controlling the sanitation vehicle to be in a pure hydraulic driving mode or a hybrid power mode, and providing necessary power. While the sanitation vehicle travels, sanitation operation can be performed, so that time is saved, and meanwhile, an energy source is also saved; according to the energy of the hydraulic energy-storing device, the sanitation vehicle is controlled to be in the pure hydraulic driving mode or the hybrid power mode, so that the power requirement of the sanitation vehicle during work is met.

Description

technical field [0001] The invention relates to a power system and a power control method of a sanitation vehicle, belonging to the technical field of hybrid power. Background technique [0002] In the face of increasingly serious environmental pollution and energy crisis, energy conservation and environmental protection have become the theme of the times, and the development of green and environment-friendly vehicles has become the main development direction. As an important part of urban vehicles, sanitation vehicles are responsible for cleaning the city, while traditional sanitation vehicles generally use diesel as fuel, causing secondary pollution to urban air and the environment during the process of cleaning the city. [0003] The oil-hydraulic hybrid sanitation vehicle is a vehicle powered by diesel and hydraulic energy. It is used for cleaning and garbage transfer. It has the advantages of reducing emissions, reducing pollution, and reducing energy costs. Compared w...
