2(3) be fixed to sun wheel and on adorning the planet pinwheel Z of active pointer tooth (2)
1(1) is satellite gear, their formations that is meshing with each other, planet pinwheel Z
1(1) goes up nearly cylindrical and establish j uniform W through hole, cycloidal gear Z
2(3) hole of A, B is established at Y-axis center, establishes circular groove C on its cylindrical, and establishes three uniform radial hole a, b and A, B hole in groove.
2, motion output mechanism: be the hole pin mechanism, angular velocity ratio mechanism such as title again, it contains j root cylindrical pin (5), fixing isometric powder metallurgy sleeve is housed on it, and supporting needle bearing (6) is rotation flexibly, becomes the cylindrical pin assembly, by j W hole on its polyphone planet pinwheel, and left end cap (7), right end cap (8) go up j pin-and-hole together, and assembling and positioning constitutes with nut screwing clamping.
Establish three in the end cap endoporus of the left and right sides every 45 ° of radial hole C, communicate with crescent d on the medial surface.The D groove change area size and position, can contain the tooth cavity district of height oil separately, the d groove radian size on the left end cap (7) should be less than ∠ CPN (two pin teeth institute be to generating angle), the d groove radian size on the right end cap can be by the bigger ∠ CPN of hand of rotation.The space quadrature of the crescent d assembling on the end cap of the left and right sides is 180 °.
3, the oil circulation structure: it contains the hydraulic gear that engagement is paid, hole pin mechanism with motion output, be exactly constructional feature and this condition of assembly relation of utilizing dexterously in them, independent sealed as each tooth cavity that engagement is paid, its line of centres boundary is high-low pressure oil tooth cavity district, again on the end cap of the left and right sides crescent d assembling with standard high-low pressure oil tooth cavity district separately, circular groove C is equipped on the left and right sides spindle nose of the endoporus of left and right sides end cap and cycloidal gear, three every 45 ° of radial hole C alignings, just constitute a P → A → a → C → c → d → high pressure oil tooth cavity district, the low pressure oil Po behind the transformation of energy lacks the valve plate distribution mode oil duct of synchronous concentric running in the sky from the simple and direct of low pressure oil tooth cavity district → d → c → C → b → B.
4, oil circuit hermetically-sealed construction: at first to cycloidal gear Z
2(3) circular groove C two sides on the left and right sides spindle nose, if O shape circle radial seal, secondly, on left end cap (7), right end cap (8) medial surface, pay tooth cavity district institute to the ring surface inside and outside with engagement, if two road O shape circle side seals, radial to two of left and right sides crescent then, if O shape vertical element side seal two, the stifled high-low pressure oil tooth cavity district plane seepage that is produced because of planet pinwheel transport motion of cutting off, like this, with open-and-shut structure, make hydraulic oil pipe system obtain comprehensive sufficient sealing, guarantee that the raising of Volumetric efficiency plays very vital function.
Two, rim for automobile wheel assembling
After independent fluid power road wheel hydraulic unit is formed integral body, through with the endoporus assembling and positioning of left end cap (7), right end cap (8) cylindrical and rim for automobile wheel, also can adopt end face endoporus assembling and positioning to get final product, constructional drawing shown in Fig. 5, be under the big situation of vehicle load, can adopt this structure that the version of oil circuit is set, be convenient to like this captive joint with vehicle frame with flange.
Three, the assembly relation of independent fluid power road wheel
Structure adopts band left and right sides spindle nose cycloidal gear Z
2(3) be fixed, be sun wheel, make reference for assembling spare again, and go up the pinwheel Z of dress rotation pin tooth (2)
1(1), is satellite gear, around cycloidal gear Z
2(3) center O
2Make directed transport motion.And with j root cylindrical pin assembly (5), needle bearing (6), penetrate in j the W hole of planet pinwheel, again with left end cap (7), right end cap (8), after angular contact bearing (4) assembling and positioning on the left and right sides spindle nose that is contained in cycloidal gear, simultaneously on the end cap of the left and right sides pack on two spindle noses of j root cylindrical pin assembly in j hole, use nut screwing clamping, just be assembled into the hydro-mechanical unit of independent fluid power road wheel.
Planet pinwheel (1) is answered consistent with the gauge tolerance of cycloidal gear (3), with the synthetic tolerance of the assembly clearance of left end cap (7), right end cap (8), its precision should be B (H/f) and is higher than 6 grades, so cylindrical pin (5) is gone up one of reason that adopts isometric powder metallurgy sleeve (14), be the usefulness of making the conditioning ring of precision levelling.

2(3) be meshed on.Its engagement tooth cavity is all independent sealed separately, by its line of centers line O
1O
2Boundary when input pressure in the high pressure oil tooth cavity district is oily, just promotes satellite gear Z for high-low pressure oil tooth cavity district
1(1), with O
2For centre of gration, be radius, make continuous transport motion along the tooth cavity direction of expansion with eccentric throw A, meanwhile, fluid is pressed the oil return line oil sump tank in the low pressure tooth cavity district.
Because planet pinwheel Z
1(1) nearly cylindrical is provided with j W hole, and its radius is Rw, and the radius of turn of this hole W is P, around its O
1Rotation.And needle bearing (6) radius of the cylindrical pin (5) on the left end cap (7), right end cap (8) and kink is Rp, and its radius of turn also is P, around its O
2Rotation.Because of O
1O
2=A=Rww-Rp is again because of O
1Ow=O
2Op=P constitutes a parallelogram O
1O
2OwOp is as satellite gear Z
1When (1) obtaining an absolute angle speed omega, j W hole involves cylindrical pin (5) by needle bearing (6), drives left end cap (7), right end cap (8), around O
2The center makes movement drive give wheel to output speed n and moment of torsion M also with the angular velocity omega rotation.
