Problems solved by technology

[0002] At present, most of the commonly used airport equipment travel transmission systems are mechanical gearbox transmission systems. Because of the low-speed driving safety requirements of airport equipment (V≤25Km / h), ordinary second-class chassis (gearboxes usually have 4-5 forward gears) are used for reconstruction. airport equipment does not meet this security requirement
Even if the speed limit is used to meet this requirement, the comfort of vehicle operation will be greatly reduced

Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings.

[0010] exist figure 1 , 2 Among them, the flywheel end of the diesel engine 1 is directly connected to the input shaft of the variable displacement plunger pump 2 through a coupling, and the variable displacement plunger pump 2 is connected to the quantitative plunger motor 4 with a hose 3, and the fixed displacement piston motor passes through a split The box 5 is connected to the final drive 6 of the axle after amplifying the torque. The speed acquisition control unit 7 acquires the rotational speed of the engine as an input signal to control the displacement change of the variable pump to realize the speed change of the motor, thereby driving the whole equipment to move.

[0011] The speed acquisition control unit 7 collects the rotational speed of the engine as a signal, and controls the change of the displacement of the variable plunger pump 2 through the input ...

Abstract

The invention provides a walking transmission system for airport equipment, which ensures the speed controllability and comfortableness of the airport equipment, can realize continuous variable transmission and ensures operating comfortableness. The system comprises an input shaft and a variable pump which is connected with the flywheel end of an engine, wherein the oil inlet and the oil outlet of the variable pump are communicated with the oil outlet and the oil inlet of a hydraulic motor through hydraulic pipelines respectively.

Description

Technical field [0001] The invention relates to a traveling transmission system for airport equipment, which is mainly used in airport equipment to replace mechanical transmission. Background technique [0002] At present, most of the commonly used airport equipment travel transmission systems are mechanical gearbox transmission systems. Because of the low-speed driving safety requirements of airport equipment (V≤25Km / h), ordinary second-class chassis (gearboxes usually have 4-5 forward gears) are used for reconstruction. The airport equipment cannot meet this security requirement. Even if the speed limit is used to achieve this requirement, the comfort of vehicle operation will be greatly reduced. Contents of the invention [0003] The purpose of the present invention is to provide a travel transmission system for airport equipment that ensures the controllability and comfort of the airport equipment in terms of speed, and can realize stepless speed change and ensure the...
