Abstract
A hydraulic controller of gear case used by steamboat comprises a hydraulic controlling valve body, the valve cavity of the vale body is provided with a time-delay piston, and the left and right sides of the time-delay piston are pressed by a spring. The spring of the time-delay piston is a combined spring formed by two springs of different diameters, and the combined spring is formed by two springs which are nested together with each other, and the diameters of the two spring are variable in size, the length of one spring is bigger than the length of the other spring, and the combined spring is formed by that one small-diameter spring is nested in the other big-diameter spring , and the length of the small-diameter is bigger than the length of the big-diameter spring. The device has the characteristics that the structure is simple, and the utilization is convenient and reliable, clutch can be kept to combine stably and softly, impact noise generated during control of gear case is reduced or eliminated, the service life of gear box is extended, and the like.
Description
Technical field
The utility model relates to a kind of be exclusively used in the reversing of marine gearbox, major control boats and ships, ahead running, the hydraulic control device of function such as parking.
Background technique
The hydraulic control device that is exclusively used in marine gearbox not only has the reversing of control boats and ships, ahead running, parking function, and its control oil pressure performance quality is controlled quality to gear-box significant impact is arranged, its structure composition mainly includes the hydraulic control valve body, in the valve pocket of valve body, be placed with the left and right sides respectively roof pressure the time-delay piston of spring is arranged, it engages instantaneous at solenoidoperated cluthes, because the pressure oil of the throttling pore piston that at the uniform velocity promotes to delay time is moved to the left on valve body, under the effect of two spring forces, oil pressure is approximate linearly rises progressively, see A line segment shown in Figure 2, it is big to make that clutch plunger moves axially fast instantaneous impacting force, the friction plate sliding wear time is short, so cause gear-box to produce bigger clutch, make the user be difficult to bear in conjunction with impact noise.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, makes clutch accomplish the hydraulic control device of the marine gearbox that smooth engagement is soft, impact noise is eliminated substantially in actual use and provide a kind of through improvement.The utility model mainly includes the hydraulic control valve body, in the valve pocket of valve body, be placed with the left and right sides respectively roof pressure the time-delay piston of spring, the cluster spring that the spring that the spring of described time-delay piston is differed by two diameter constitutes are arranged.
Described cluster spring is made of two mutual sheathing spring together, that diameter differs, and wherein the length of a spring greater than the length of another root spring.
Described cluster spring is nested with at another root major diameter spring by minor diameter spring wherein and constitutes, and the length of minor diameter spring is greater than the length of major diameter spring.
The utility model belongs to the improvement to prior art, and it has simple in structure, and is easy to use, reliable, can make the soft combination of clutch smooth and steady, reduces or eliminates the impact noise that gear-box when control produces, and prolongs characteristics such as gear-box working life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is prior art and oil pressure accelerated curve figure of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
Shown in Figure 1, the utility model mainly includes hydraulic control valve body 1, in the valve pocket of valve body 1, be placed with the time-delay piston 2 of top pressure spring 3,4, the cluster spring that the spring that the spring 3,4 of described time-delay piston 2 is differed by two diameter constitutes, cluster spring shown in the figure is made of the spring that two mutual sheathing diameter together differs, on wherein a minor diameter spring 4 is nested with in another root major diameter spring 3, and the length of minor diameter spring 4 is greater than the length of major diameter spring 3.
Said structure can be realized the oil pressure shown in Figure 2 B line segment curve of rising progressively, and the long sliding wear time is arranged, and makes the soft combination of clutch smooth and steady.During parking by the low initial oil pressure of minor diameter spring controlled hydraulic system, the oil pressure of the effect controlled hydraulic system process of rising progressively by the size diameter spring assembly when reversing or ahead running.
Claims (3)
