Description
Technical field
The utility model relates to a kind of high-power wheel-tire tractor clutch operation, belongs to trac. master clutch manipulation technology field.
Background technology
Wheel-tire tractor master is made up of driving engine, transmission device, steering hardware, stop mechanism and the traveling gear and the operating mechanism etc. that are arranged on vehicle frame, and transmission device in order to by the transmission of power of driving engine to drive wheel and power take-off mechanism.And clutch equipment in transmission system is mainly made up of master clutch, pull bar and clutch foot lever assembly etc., the transmission by master clutch control power and cut off power.
And adopt the normal engaging clutch of dry type friction lining for the master clutch of wheel-tire tractor at present, realize joint or the separation of power by the action of control clutch treadle assembly control platen.But the normal engaging clutch of dry type friction lining in starting or when gearshift often in sliding wear state, can produce clutch fading or separate the phenomenons such as not thorough because the friction lining of power-transfer clutch constantly weares and teares, therefore need to adjust in time clutch play, and liquid clutch has overcome the shortcoming of dry type clutch, improve the service life of master clutch, there is starting, shift gears softly, need not adjust the advantage of clutch play.
The on-off control mechanism of wheel-tire tractor has mechanical type steering unit and the hybrid steering unit of hydraulic machinery.The former is modal maneuverability pattern, and because its actuating force increases with trac. horsepower, thick stick part efficiency is lower simultaneously, so generally only use on fraction horsepower or middle horsepower section trac.; The latter compares with the former, and actuating force and driving efficiency all have greatly improved, but the latter's complex structure.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, and actuating force is little, manoeuvring safety failure-free high-power wheel-tire tractor clutch operation.
The utility model is that the technical scheme achieving the above object is: a kind of high-power wheel-tire tractor clutch operation, it is characterized in that: comprise clutch foot lever assembly, photoelectric sensor and for detection of the angular transducer of clutch foot lever assembly rotational angle, angular transducer and photoelectric sensor are arranged on respectively on support, on support, there is upper limit seat and lower limit seat, adjustable position-limited lever is arranged on respectively on upper limit seat and lower limit seat, the rotary head of angular transducer is hinged by the swing arm of connecting rod and clutch foot lever assembly, the upper base plate of clutch foot lever assembly is provided with the deep-slotted chip breaker corresponding with photoelectric sensor, the two ends of pull back spring are connected on the spring perch of support and the spring perch of clutch foot lever assembly, the signal input part of the output termination electrohydraulic control apportioning valve of the mouth of angular transducer and photoelectric sensor, the mouth of electrohydraulic control apportioning valve is connected with the oil pocket of oil pump and damp flywheel clutch respectively by oil pipe.
The utility model is provided with the angular transducer and the photoelectric sensor that detect clutch foot lever assembly rotational angle on support, when chaufeur is stepped on clutch foot lever assembly, drive angular transducer rotary head to rotate, angular transducer detects handles treadle assembly rotational angle, and by angle signal electric signal input electrohydraulic control apportioning valve, by electro-hydraulic proportional valve oil pump control oil pressure direction, and control liquid clutch action, realize joint or the separation of power.In the time that chaufeur depresses clutch foot lever to lower limit, if angular transducer does not reach output voltage requirement for a certain reason, photoelectric sensor directly outputs signal to electrohydraulic control apportioning valve, and electrohydraulic control apportioning valve is closed, and realizes disengaging of clutch.When the utility model only changes clutch foot lever assembly, angular transducer is connected with electrohydraulic control apportioning valve with photoelectric sensor, simple in structure, the control clutch action by electrohydraulic control apportioning valve, make the manoeuvring safety of power-transfer clutch reliable, the elastic force that only need to overcome pull back spring when operation is stepped on treadle and just can realize the separation of power-transfer clutch, and whole steering unit actuating force is little.
