Abstract

The utility model discloses a median position picker of a hydraulic pressure transmission device, comprising a variable sloping plate (1) and an end cover (2). The utility model is characterized in that the variable sloping plate (1)'s gudgeon head face is equipped with a locating hole (6), at whose correspondence position the end cover (2) is arranged with a thread through-hole. A steel ball (4) and a spring (5) are arranged inside the thread through-hole wherein a plug (3) is also equipped. The plug (3) press the steel ball (4) into the variable sloping plate (1)'s gudgeon head face or in the locating hole (5) of the variable sloping plate (1)'s gudgeon head face by the spring (5).The utility model has the advantages of simple structure, easy components' processing difficulty, low cost, convenient installation and maintenance. The utility model greatly helps the operator to feel the median position obviously and to be capable of maintaining the hydraulic pump in the ideal median position state. The utility model also makes the mainframe operations more convenient and reduces the load on the engine and fuel consumption when mainframe is in the standby mode.

Description

The meta positioning device of hydraulic transmission
Technical field
The utility model relates to the meta positioning device at a kind of hydraulic pressure positioning device, particularly hydraulic transmission.
Background technique
In hydraulic transmission,, change pump delivery (the meta discharge capacity of pump is zero), thereby realize infinite variable speed purpose by changing operating grip pivot angle angular dimension.And in actual use, main frame is under holding state, because the host service function person can not feel meta, so the pivot angle of variable swash plate can not be in the zero degree state, the pump of hydraulic transmission is also being worked, thereby has increased the load of motor, and fuel consumption is big.
The model utility content
The purpose of this utility model is: a kind of novel hydraulic transmission device meta positioning device is provided.Make the variable swash plate pivot angle of hydraulic transmission be in the zero degree state, reduce load, reduce fuel consume, realize host service function person's ease for operation motor.
The technical solution of the utility model: a kind of meta positioning device of hydraulic transmission, comprise variable swash plate 1 and end cap 2, gudgeon end face at variable swash plate 1 is provided with positioning hole 6, on end cap 2, be provided with tapped through hole with positioning hole 6 corresponding positions, be provided with steel ball 4 and spring 5 in the tapped through hole, screw plug 3 is screwed in the tapped through hole, and screw plug 3 is pressed in steel ball 4 in the positioning hole 6 of gudgeon end face of the gudgeon end face of variable swash plate 1 or variable swash plate 1 through spring 5.
Compared with prior art, meta positioning device structure of the present utility model is simple, and the part processing difficulty is little, and cost is low, and is convenient for installation and maintenance, helps the operator and can obviously feel and make host service function more convenient by meta; Also can realize main frame under holding state, the pump of hydraulic transmission is in desirable meta state, reduces the load to motor, reduces the consumption of fuel oil.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the utility model working positions in hydraulic transmission;
Being labeled as in the accompanying drawing: 1-variable swash plate, 2-end cap, 3-screw plug, 4-steel ball, 5-spring, 6-positioning hole.
Embodiment
Embodiment.As shown in Figure 1, a kind of meta positioning device of hydraulic transmission, comprise variable swash plate 1 and end cap 2, gudgeon end face at variable swash plate 1 is provided with positioning hole 6, on end cap 2, be provided with tapped through hole with positioning hole 6 corresponding positions, be provided with steel ball 4 and spring 5 in the tapped through hole, screw plug 3 is screwed in the tapped through hole, and screw plug 3 is pressed in steel ball 4 in the positioning hole 6 of gudgeon end face of the gudgeon end face of variable swash plate 1 or variable swash plate 1 through spring 5.Shown in Figure 2 is the working position of the utility model in hydraulic transmission.
During concrete enforcement, a processing M10 tapped through hole (accuracy of thread and limit deviation value are with reference to GB/T197-1981) on the end cap 2 of existing hydraulic transmission, Φ 5 positioning holes 6 of processing on the gudgeon end face of variable swash plate 1, positioning hole 6 aperture chamferings are not more than 0.3 * 45 °, tapped hole and positioning hole should satisfy when part processing variations per hour swash plate 1 pivot angle is in the zero degree position, and the coaxality in two holes should be not more than 0.5mm.Screw plug 3 centers that cooperate with tapped hole process flat circular hole, and flat circular hole size should be than the big 0.1~0.2mm of steel ball 4 diameter dimensions, than the big 0.5~1mm of spring 5 outside dimensions; The accuracy of thread of screw plug 3 should reach GB/T197-1981 medium more than, evenly be coated with thread locking adhesive at screw plug 3 screw threads during assembling, solidify more than 24 hours.The distance of variable swash plate 1 cylinder end face and screw plug 3 should be controlled between 1/10~1/8 steel ball, 4 diameters.Can select different springs 5 elastic force according to concrete hydraulic transmission, and steel ball 4 sizes.

Claims (1)

1. the meta positioning device of a hydraulic transmission, comprise variable swash plate (1) and end cap (2), it is characterized in that: the gudgeon end face at variable swash plate (1) is provided with positioning hole (6), go up and positioning hole (6) corresponding position is provided with tapped through hole at end cap (2), be provided with steel ball (4) and spring (5) in the tapped through hole, screw plug (3) is screwed in the tapped through hole, and screw plug (3) is pressed in steel ball (4) in the positioning hole (6) of gudgeon end face of the gudgeon end face of variable swash plate (1) or variable swash plate (1) through spring (5).
