For solving its technical matters, the technical solution adopted in the utility model is: this special axle comprises rear-axle casing, front gear box body, semiaxis and braking hub, drg, core wheel composition; Casing is provided with and is provided with conversion gear device and two groups of two-stage deceleration gears and diff in oil motor, the casing.Conversion gear device is by the terminal little tooth that slides, an end that makes terminal little tooth and the coaxial interior engaging tooth engagement that keeps off passive tooth soon, slowly that is located in the front gear box body, and the other end of terminal little tooth and the engagement of terminal canine tooth become fast retaining or keep off slowly; The terminal little tooth that slides, being in is not neutral with the interior engaging tooth position engaged of keeping off passive tooth soon, slowly.Two groups of deceleration gears are to realize by two last keeping off passive tooth slowly, soon and being located at the constant-mesh that keeps off driving tooth on slowly, soon of being provided with in the front gear box body.
This special axle has carried out the improvement of three aspects to former vehicle bridge: 1. the vehicle bridge casing is changed into split typely, wherein the front portion is divided into gearbox body, and trailing portion and main bearing part change sphere into, make integral body (being commonly called as rear-axle casing) with the semiaxis conduit; 2. add at the inner ring that keeps off passive tooth and fast retaining passive tooth slowly and mill interior engaging tooth, two passive tooth respectively by bearing installation on two, and be in the constant-mesh state simultaneously with two corresponding driving tooths on one; 3. change the little tooth of end lengthening into slide teeth,, make the one end be meshed the then long-term and terminal canine tooth engagement of the other end with the interior engaging tooth that keeps off passive tooth slowly or keep off passive tooth soon respectively by the terminal little tooth that slides.
The beneficial effects of the utility model are: 1. owing to the main carrying position with the vehicle bridge casing changes sphere into and makes integral body with the semiaxis conduit, strengthened load-carrying capacity; 2. owing to change the little tooth of end into slide teeth, and by with the engagement of the interior engaging tooth that keeps off passive tooth soon, slowly with separate the implementation shift transformation, the linear velocity when having reduced the slide teeth engagement has changed the operating characteristic of vehicle bridge gear, makes it to operate more convenient; 3. because soon, slowly the retaining master, passive tooth be in the constant-mesh state, prolonged the service life of gear; 4. because when neutral gear position, terminal little tooth with keep off passive tooth soon, slowly and all be in complete released state, thereby reduced car resistance, strengthened sliding.
[description of drawings] the utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 braking hub, 2 drgs, 3 front gear box bodies, 4 semiaxis, 5 rear-axle casings, 6 core wheels, 7 terminal canine tooths, 8 terminal little teeth (slide teeth), 9 keep off passive tooth, 10 2,11 fast retaining passive tooth slowly, keep off driving tooth, 14 fast retaining driving tooths, 15 adapter sleeves, 16 oil motors, 17 difies slowly for 12 1,13.
[specific implementation method] is with reference to accompanying drawing 1: drg 2, core wheel 6, braking hub 1 all are installed at the two ends of rear-axle casing 5.One end of every semiaxis 4 is equipped with spline, and with rear-axle casing 5 in the diff 17 of terminal canine tooth 7 one in the semiaxis tooth be meshed; The other end of semiaxis 4 links to each other with core wheel 6 by double-screw bolt.Each braking hub 1 arrives core wheel 6 by bolt, in order to scroll forward and backward.There are two 10, two 10 and are provided with by bearing fixing at front gear box body 3 rear portions and keep off passive tooth 9 slowly, keep off passive tooth 11, terminal little tooth (slide teeth) 8 soon.Slowly keep off passive tooth 9, soon keep off passive tooth 11 by bearing installation on two 10.Three gap bridge tooth forward or reverse on these two 10 can drive terminal canine tooth 7 forward or reverse, and drive braking hubs 1 by semiaxis 4 and advance or retreat.Front portion at front gear box body 3 has one 12 by bearing fixing, and a side of front gear box body 3 front portions is equipped with oil motor 16 by bolt.An end of one 12 links to each other with oil motor 16 by adapter sleeve 15.Be provided with for one 12 and keep off driving tooth 13 and fast retaining driving tooth 14 slowly.Slowly keep off driving tooth 13, keep off driving tooth 14 soon and keep off passive tooth 9 slowly, keep off passive tooth 11 soon and be in the constant-mesh state respectively.Since slowly keep off passive tooth 9, soon keep off passive tooth 11 be by bearing installation on two 10, when the interior engaging tooth that keeps off passive tooth 9 slowly, keeps off passive tooth 11 soon during with the little tooth of end (slide teeth) 8 engagements, hurry up, main, the passive tooth of retaining all is in idling conditions slowly, forms neutral.When the terminal little tooth (slide teeth) 8 that slides makes it to mesh simultaneously with the interior engaging tooth of fast retaining passive tooth 11 and terminal canine tooth 7, become fast retaining; When the terminal little tooth (slide teeth) 8 that slides makes it to mesh simultaneously with interior engaging tooth that keeps off passive tooth 9 slowly and terminal canine tooth 7, become retaining slowly.Specific operation process is: a, oil motor drive vehicle bridge work.Handle terminal little tooth (slide teeth) 8, terminal little tooth (slide teeth) 8 and the interior engaging tooth and the terminal canine tooth 7 that keep off passive tooth 9 slowly or keep off passive tooth 11 soon meshs simultaneously, oil motor 16 driving vehicle bridge are advanced or are retreated.Use retaining slowly when needing torsion big, otherwise keep off with fast.B, oil motor do not drive vehicle bridge work.Handle terminal little tooth (slide teeth) 8, terminal little tooth (slide teeth) 8 is not meshed with the interior engaging tooth that keeps off passive tooth 9 and fast retaining passive tooth 11 slowly, terminal little tooth (slide teeth) 8 is in neutral gear position, and oil motor 16 drives soon, retaining master, passive tooth idle running do not drive vehicle bridge slowly.C, pilot oil way reversing valve change the direction of oil stream in the oil motor 16, and by oil motor 16 forward or reverse, thereby the driving vehicle bridge is advanced or fallen back.
