Shift.
And for Hydrodynamic transmission hydraulic control system, such as fluid power speed change disclosed in 105402350 A of Chinese patent CN
The shifting control system of device realizes that the switching of each gear, the switching of every kind of gear are directed to by the opening and closing of different valves
To the opening and closing of multiple valves, touch-tone operation is usually used, operability is weak, for the operators, conventional handle
The gearshift of formula is with more operability, more intuitively and conveniently.
Summary of the invention
The technical problem to be solved by the present invention is the limitation of the button gearshift to overcome existing hydraulic transformer,
A kind of novel accurate, the faster gearshift of response are provided.
The technical scheme is that
A kind of Hydrodynamic transmission gearshift, including shell, handle ball and shifting shaft disc assembly, on the reel of shifting shaft disc assembly
End connects handle ball by connecting rod, is equipped with inductive axis in the shaft in reel center, inductive axis be parallel to sensor circuit plate simultaneously with
The cooperation of its sense contact；Sensor circuit plate connects the underground solenoid valve of controller or each gear by bundle assembly.
Shell is double-layer box body structure and is equipped with upper cover, front cover and rear cover, and shaft is mounted on shell intermediate interlayer with before
In the centre bore of lid, outer casing bottom installs stopper mechanism, has one group of continuous groove, this group of groove and lock on the lower half circumference of reel
Rolling element cooperation on retaining device.
The left and right sides of shifting shaft disc assembly is equipped with block.
The connecting rod of shifting shaft disc assembly passes through the gear identification hole on upper lid.
Upper cover lower surface installation gear is shown and processing circuit plate, digital display screen connected to it cover table positioned at upper
Face.
Gear lockplate is installed in the central baffle of shell, there is row's groove, groove and shifting shaft on gear lockplate
Stopper pin cooperation on disc assembly connecting rod.
Beneficial effects of the present invention:
The present invention is by pulling one angle of handle ball rotation, until at the gear of upper cover mark, to drive connected shifting shaft
Disc assembly is rotated around shifting shaft, under the effect of stopper mechanism, realizes gear locking, it is total that two or so blocks can limit shift reel
At the both ends extreme position of rotation.Inductive axis rotation is driven to streak acquisition electric signal in gear sensor circuit plate surface simultaneously, electricity
Signal is conducted to gear by socket and bundle assembly and shows and processing circuit plate and external controller (or various gears electromagnetism
Valve), final realize shows the control of Hydrodynamic transmission various gears solenoid valve power on/off and gear.Use different shape card slot
Gear lockplate, card slot can block the stopper pin in shifting shaft disc assembly, and switching is certainly between determining more gears of Hydrodynamic transmission
By non-resistance switching, have resistance switching still press locking press button after switch.
Detailed description of the invention:
Fig. 1 is forward structure schematic diagram of the invention.
Fig. 2 is sectional view along AA of the invention.
Fig. 3 is that the gear on upper lid identifies schematic diagram.
Specific embodiment
Embodiment: as shown in Figure 1, the handle ball 1 containing locking press button passes through the shifting shaft disc assembly 2 of screw and the pin containing stopper
Connecting rod be connected, two pieces or so block 3 limit shifting shaft disc assembly rotation both ends extreme angles, to limit the gear at both ends
Position, can decrease or increase Hydrodynamic transmission gear number, and in the present embodiment, there is engraved structure in reel center, then in left and right
Two hollow out positions setting left and right, two blocks 3.Shell 8 is double-deck body structure in a front and back, above, front and rear
Lower half portion aperture, tapping install upper cover 4, front cover 10 and rear cover 12 respectively, and the interlayer in 8 center of shell is locked equipped with gear
Plate 6 has groove of different shapes on gear lockplate 6, blocks the stopper pin in 2 connecting rod of shifting shaft disc assembly by groove and determines
The resistance switched between more gears.Gear is shown by screw and processing circuit plate 5 is fixed under the upper cover 4 of gear mark
, there is the digital display screen of target gear and actual gear in side above.
Shifting shaft disc assembly 2 is mainly made of connecting rod and reel, and there is a shaft 7 in reel center, shaft 7 by 8 center of shell every
The centre bore of layer and front cover 10 positions, and is equipped with inductive axis 9 in shaft 7, shifting shaft disc assembly 2, shaft 7 and inductive axis 9 can be same
Step rotation.Stopper mechanism 14 is fixed on 8 bottom of shell, there is the half of a toothrow colyliform on the lower circumference of 2 reel of shifting shaft disc assembly
Circular groove, semi-circular recesses can cooperate with the rolling element of stopper mechanism (14) realizes that each gear limits, peace below rolling element
Equipped with spring.Gear sensor circuit plate 11 is fixed on the interlayer in 8 center of shell, and gear sensor circuit plate 11 and inductive axis 9 are flat
It goes, one group of sense contact on inductive axis 9 and gear sensor circuit plate 11 matches, from sensor circuit plate when inductive axis 9 rotates
It is streaked on 11, generates different electric signals, electric signal is conducted to gear by bundle assembly 13 and show and processing circuit plate 5 and outside
The controller (each solenoid valve in hydraulic control system) connect.
