Problems solved by technology

The so-called open hydraulic system, that is, the oil supply is carried out under natural normal pressure. Because the pressure of the oil supply is low, in order to avoid the suction of the oil pump, the oil supply groove of the oil pump distribution plate is generally lengthened. Improve the oil suction condition of the oil pump, but this will slow down the pressure boost of the oil pump, especially when the oil pump working condition is switched to the hydraulic motor working condition, the output torque of the hydraulic motor will be reduced due to the increase of the oil distribution tank

Abstract

The invention relates to a hydraulic device with a pneumatic pressurizing oil tank and for an oil liquid hybrid power bus. The pressure of hydraulic oil in the hydraulic oil tank is pressed into an axial plunger pump to form pressure oil supply and form a closed hydraulic system by utilizing air pressure of an air compression device of a motor bus aiming at the shortcomings of use of an open hydraulic system on an oil liquid hybrid power motor bus. The hydraulic device utilizes cylindrical air cylinders and oil cylinders to replace a traditional hydraulic oil tank, has the advantages of being small in size, simple in structure and quick in force exertion. Generation of hydraulic force does not require extra driving force, noise and vibration of the hydraulic system are reduced, and the hydraulic device is suitable to be popularized in and applied to the oil liquid hybrid power motor bus.

Description

technical field [0001] The invention relates to an oil-hydraulic hybrid bus used for urban public transport vehicles, which is used to solve the problems of slow output, loud noise and vibration of hydraulic pumps existing in traditional oil-hydraulic hybrid buses. Zhongneng can shorten the time of energy storage, increase the output torque and output speed, drive stably, and achieve the effect of energy saving and emission reduction. It belongs to the field of transportation. Background technique [0002] Due to the limitation of vehicle space and weight, the existing oil-hydraulic hybrid bus technology adopts the form of one pump with multiple functions, that is, the plunger pump is in the hydraulic pump mode through the switching of the control system during energy storage, and the energy is in the hydraulic pump mode. In the release stage, the plunger pump is in the hydraulic motor state through the switching of the control system. Due to the structure of the axial pis...
