Abstract
The utility model discloses a mini-typed servo hydraulic steering engine, which is used for mini-typed motor ships. The steering engine adopts the general cycloid type rotary valve reverser in common engineering machines. A steering engine system is composed of an end hinge type oil cylinder and a special combination valve. The steering speed can be selected in a stepless mode. During the malfunction of an oil pump system, the system has use ability to suit the emergency for many times. During no steering, the system has the running ability by unloading.
Description
The invention belongs to ship machinery, steering gear system.
The steering wheel that general motor-driven spitkit uses, the hydraulic efficiency pressure systems that adopt more, liquid oil is for transmitting the medium of control steering wheel rotation direction signal, and total system is to be formed by connecting by fuel tank, oil filter, oil pump, check valve, change-over valve, oil cylinder, piston, tiller and oil pipe.Oil pump can be formed by several, has only a job, other is standby, for preventing that oil from flowing backwards along stand by pump, every pump output terminal is equipped with check valve, send into change-over valve by check valve, change-over valve is connected with the operator platform handle, and mostly existing change-over valve is the 3-position 4-way guiding valve, makes the four-way cock shift position by the manpower handle, connect and close relevant path, make with the two ends of change-over valve bonded assembly oil cylinder positive and negative different pressure to occur, force piston to move, the rudderpost that is connected on the piston is rotated to an end, the drive rudder blade rotates, and ship can turn to thereupon.In order to guard against the oil pump systems et out of order, also be furnished with pressure accumulator, pressure accumulator is the airtight container that a 150-300 rises, liquid oils and pressurized air are housed, when the oil pump et out of order, the high pressure oil of pressure accumulator can be done emergent the use by change-over valve, generally can only use several times, ineffective because of pressure decay, this cover system volume is big, heaviness, emergent access times are limited, dangerous.
Guiding valve is adopted in commutation, and during commutation, time constant is little, and oil pressure raises too fast, and rudder blade is subjected to torrent and impacts, and when resistance was excessive, this system can be subjected to impacting with high pressure, exceeded system's ability to bear, made pipeline breaking, and the mechanical part damage causes the accident.
When three-position four-way valve adopts O type path; When steering wheel does not turn to, the high pressure oil impassabitity change-over valve that oil pump is got, and arrive fuel tank by by pass valve, by pass valve must just can be opened when oil pressure surpasses a rated value, this just makes oil pump be in loading condition always, promptly wastes energy and mechanical wear is accelerated.
Purpose of the present invention is improved in existing steering gear system, adopts all-hydraulic steering gear to replace change-over valve.The pressure accumulator of heaviness is saved; The use of repeatedly meeting an urgent need again; During diverter valve imoperative, oil pump should be in unloaded state; And having the steady rudder performance of good self-locking, simplied system structure is convenient to installation and maintenance.Than original weight with shelves specification product light 2/3.
Formation of the present invention is, with the hinge of the end in common mechanical formula oil cylinder, pushes away rudder gear as steering wheel, and single oil cylinder can be with two oil cylinders.Commutator is designed to cycloid formula rotary valve commutator, is combined into the special service valve group and existing oil pump systems constitutes steering gear system by the sequence valve that surges, little fuel tank, check valve.
Effect of the present invention: 1. owing to adopted cycloid formula rotary valve commutator, the amplitude of oil pressure changes in the commutation process, is cycloid in time and changes, and hydraulic efficiency impact is little, and oil pipe is difficult for breaking, and mechanics is easy damaged not also.2. cycloid formula rotary valve self has short circuit device, and when steering wheel did not turn to, the high pressure oil of oil pump was directly got back to fuel tank by the M type passage of commutator, and the oil pump load is very little, equals the unloading operation, reduces energy consumption and mechanical wear.3. cycloid formula rotary valve commutator, spool is made up of servo valve, cycloidal pinion engaged pair, rotor etc.Poppet shaft and bearing circle link together, during power steering, the oil of oil pump input enters cycloidal pinion engaged pair through servo valve, promotes rotor and follows the bearing circle rotation, and quantitative oil pressure is gone into a certain oil cylinder promotion track adjusting wheel realize power steering, the oil of another oil cylinder is got back to fuel tank.When oil pump quits work,, drive rotor by poppet shaft hydraulic oil is pressed into another oil cylinder promotion track adjusting wheel realization manual steering by an oil cylinder by the human control bearing circle.Commutator plays the effect of artificial oil pump, and this emergent use is not subjected to the restriction of number of times.4. and pressure accumulator saves, the steering wheel volume-diminished, weight saving, cost reduces, and safety improves.
Shown in the accompanying drawing, be a steering gear system scheme drawing of the embodiment of the invention.Following parts are wherein arranged:
(1) be the fixing tiller of rudderpost, two ends connect an end of piston rod (2) with bearing pin.
(2) be piston rod, an end connects together with (1), and the other end is connected on the piston.
(3) oil cylinder.
(4) rocker bar bearing of fixed oil cylinder.
(5) little fuel tank is contained in the special combination valve (8).
(6) hydraulic control one-way valve.
(7) cycloid formula rotary valve.
(8) special combination valve, comprising hydraulic control one-way valve (6), little fuel tank (5), the by pass valve that surges (13), check valve (10) is fitted together formation combine valve group.
(9) fuel tank, in oil filter is housed.
(10) check valve.
(11) oil pump unit is formed by two, by power driven.
(12) shutoff valve.
(13) by pass valve that surges.
One embodiment of the present of invention, oil pump (11) is formed by two, shutoff valve (12), check valve (10), fuel tank (9), in oil filter is housed, can make hydraulic oil pure, the by pass valve that surges (13), when oil pressure is too high, spring is backed down, hydraulic oil flows to fuel tank by this valve.Cycloid formula rotary valve (7), external artificial runner, its valve is provided with, and when rotating handwheel, the variation of hydraulic fluid flow rate is cycloid in time and changes.When steering wheel does not turn to, there is a path to make oil pump and fuel tank short circuit in the rotary valve (7), hydraulic oil is got back to fuel tank along this path, and oil pump is in the unloading operation.
Controllable check valve (6), the unlatching of valve steel ball have two controls, and the hydraulic oil positive pressure is backed down ball, and oil flows out; The control stalk of steel ball below is subjected to the control of another road hydraulic oil, when hydraulic pressure raises this bar is compressed into steel ball is backed down, and oil can flow backwards along check valve, and the setting of these two check valves (6) makes the pressure of oil cylinder be in locking-in state when not coming about.
Oil cylinder (3) one ends are fixed on flap (4) with bearing pin and constitute end hinge formula oil cylinder.Piston (2) is connected rudderpost (1), and rudder blade is equipped with in the rudderpost lower end.
