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
Affiliated technical field
The present invention relates to a kind of airfield equipment walking driving system, it mainly is used in and is used for substituting mechanical drive on the airfield equipment.
Background technology
At present, airfield equipment walking driving system commonly used mostly is the mechanical gear box driving system greatly, because the low speed driving safety requirements of airfield equipment (V≤25Km/h), select for use the airfield equipment of common two class chassis (the common 4-5 of a change speed gear box D Drive) transformation of the way can not satisfy this safety requirements.Both just reached this requirement, big heavy discount on the traveling comfort of vehicle operating with speed limit.
Summary of the invention
The purpose of this invention is to provide controllability and the traveling comfort of assurance airfield equipment on speed, and can realize electrodeless variable-speed, guaranteed the airfield equipment walking driving system of the traveling comfort of operation.
Airfield equipment walking driving system of the present invention comprises the controllable capacity pump that input shaft links to each other with the engine flywheel end, and the oil inlet and outlet of controllable capacity pump communicates with the oil inlet that goes out of HM Hydraulic Motor by hydraulic tubing respectively.
Above-mentioned driving system, described controllable capacity pump are Variable plunger pump, and described HM Hydraulic Motor is the quantitative piston motor of hydraulic pressure.Preferably, it comprises that also the rotating speed of gathering driving engine comes the speed acquisition control unit of control variable capacity of pump variation as incoming signal.
Beneficial effect of the present invention: the present invention is that a kind of quiet liquid drives the electrodeless variable-speed device, by cooperating of hydraulic pressure Variable plunger pump and the quantitative piston motor of hydraulic pressure, on aspect the power, mate with the perfection of driving engine, brought the effect higher than mechanical drive power utilization, the speed-controllable and the operation comfort of car load have greatly been improved, when emphasizing human oriented design, because no longer be mechanical connection (only linking to each other) between pump and the motor, and make that the arrangements of elements of equipment is more flexible by hydraulic tubing (flexible pipe).The present invention has replaced mechanical gear box, has remedied the shortcoming of mechanical gear box when realizing electrodeless variable-speed, and this hydostatic transmission system only has once last moves back two grades and can realize four or five effects that gear could be realized of mechanical gear box needs.Simultaneously hydostatic transmission is more outstanding than mechanical gear box on low-speed stability, operate simpler and more direct, also meet more airfield equipment at low speed, stablize, simple and direct, operate the requirement of aspect such as comfortable.
Description of drawings
Fig. 1 is a scheme drawing of the present invention.
Fig. 2 is a schematic diagram of the present invention.
The specific embodiment
The present invention is further described below in conjunction with accompanying drawing.
In Fig. 1,2, the flywheel end of diesel motor 1 directly links to each other with the input shaft of Variable plunger pump 2 by coupler, Variable plunger pump 2 is with connecting with flexible pipe 3 between the quantitative piston motor 4, and quantitatively piston motor is by being connected to the main reduction gear 6 of vehicle bridge after the auxiliary gear box 5 amplification moments of torsion.The rotating speed that speed acquisition control unit 7 is gathered driving engine changes and then realizes the velocity variations of motor as incoming signal control variable capacity of pump, thereby drives the entire equipment walking.
The rotating speed that speed acquisition control unit 7 is gathered driving engine comes the variation of the discharge capacity of control variable plunger pump 2 by controller input, thereby realizes the change in rotational speed of quantitative piston motor as signal, and being reflected on the equipment is the electrodeless variation of speed.Variable plunger pump with quantitatively can be connected by two high pressure hoses of mistake between the piston motor, when need advanced, wherein the high pressure oil of a flexible pipe entered quantitative piston motor; When need retreated, the high pressure oil of an other flexible pipe entered quantitative piston motor.And the electrodeless adjusting of speed only needs by trampling the throttle of driving engine, and operation is simple and reliable.
