Brief description of the drawings
Fig. 1 is a kind of structural representation of the gearshift of heavy-duty car transfer case of the utility model.
Specific embodiment
As shown in figure 1, a kind of gearshift of heavy-duty car transfer case of the utility model include planetary gear mechanism,
Gear ring support 7, gear ring 8, sliding sleeve 9, piston rod 4, cylinder 5, end cap 6 and gearshift casing 10.Planetary gear mechanism, tooth
Coil support 7, gear ring 8, sliding sleeve 9, piston rod 4, cylinder 5, end cap 6 are respectively positioned in gearshift casing 10.Planetary Gear Transmission machine
Structure includes that the sun discusses 2, multiple planetary gears 12 and planetary frame 13.Planetary frame 13 uses Split assembled structure.Sliding sleeve 3 is sleeved on
The middle part of piston rod 4, is provided with bearing, and sliding sleeve 3 and the axial restraint of piston rod 4 between the inner circumferential of sliding sleeve 3 and the periphery of piston rod 4.
One end of piston rod 4 is slidably connected with transfer case input shaft 11, and piston rod 4 is coaxial with transfer case input shaft 11.Piston rod 4
The piston that the other end is fixed is slidably connected with cylinder 5.When piston rod 4 is in three diverse locations with respect to transfer case input shaft 11,
Gearshift is respectively at highway gear, neutral position and cross-country gear.Cylinder 5 is fixed on end cap 6.Gear ring support 7 is sleeved on
On transfer case input shaft 11, gear ring support 7 is fixedly connected by spline with transfer case input shaft 11, and gear ring 8 is sleeved on gear ring branch
On the periphery of frame 7, gear ring 8 is fixedly connected by spline with gear ring support 7.Planetary gear mechanism is located at gear ring inner, too
Sun wheel 2 is sleeved on the periphery of sliding sleeve 3, and sun gear 2 passes through spline connection with one end of sliding sleeve 3.Sun gear 2 and multiple planetary gears
12 engagements, the wheel shaft of multiple planetary gears 12 is supported on planetary frame 13.Intermediate sleeve 14 is sleeved on the periphery of sliding sleeve 3, planet frame
Frame 13 is fixedly connected with one end of intermediate sleeve 14, and the other end of intermediate sleeve 14 is sleeved on the output shaft 15 of gearshift, and logical
Cross spline connection.Gear on gearshift output shaft 15 is engaged with the countershaft-gear of transfer case.When in cross-country gear,
The other end of sliding sleeve 3 is engaged by spline with end cap 6.
One end of gearshift casing 10 is fixedly connected with transfer case, and the other end of gearshift casing 10 is fixed with centre
Lid 1, end cap 6 is fixed on the outer face of middle cover 1.The internal splines of sun gear 2 take change transverse tooth thickness, prevent out of supply, it is ensured that planetary gear
System goes slick.
The course of work of the present utility model is that transfer case input shaft 11 is connected with output shaft of gear-box, there is two on cylinder 5
Air inlet, two air inlets are located on the cavity of cylinder piston both sides respectively, under vehicle gas cylinder is to the right side cavity effect of cylinder 5,
Piston rod 4 is relative to be slided, and piston rod 4 drives sliding sleeve 3 to slide axially during to high order end highway gear, the band of transfer case input shaft 11
Dynamic tooth set support 7 is rotated, and 2, sliding sleeve 3, planet wheel frame 13, intermediate sleeve 14, gearshift machine are discussed by gear ring 8, the planetary gear 12, sun
Rotation is delivered to transfer-case idle shaft by structure output shaft 15, realizes the highway gear of transfer case；When sliding sleeve 3 slides into middle part gear
Realize neutral position；In the case where vehicle gas cylinder is to the left side cavity effect of cylinder 5, when sliding sleeve 3 slides into the right the cross-country gear of low order end, with
Sliding sleeve 3 is combined with the middle part spline of end cap 6, and sliding sleeve 3 does not turn, and the not autobiography of sun gear 2, planetary gear 12 revolves round the sun around sun gear 2, planetary gear
Framework 13 revolves round the sun, and planet wheel frame 13 drives intermediate sleeve 14 to rotate, and is further driven to gearshift output shaft rotation, and motion is passed
Transfer-case idle shaft is passed, cross-country gear is realized.So as to realize the gearshift performance that transfer case is reached by parallel axle construction originally.
