Embodiment
Referring to Fig. 1, Fig. 2, the present invention proposes a kind of six grades of automotive transmissions, comprise casing, operating mechanism, in casing, comprise an axle 1 and two axles 26 that connect successively and the jack shaft 8 that is positioned at two axle 26 both sides and two axle 26 adaptations, one axle 1 is provided with a shaftgear, is provided with the first shifting gear, the second shifting gear, third gear gear, fourth speed position gear, the 5th shifting gear, reverse gear 25 on two axles 26, jack shaft 8 is two, on two jack shafts, be all provided with driving gear 7 and five actuation gears, driving gear 7 with and a shaftgear often mesh, five actuation gears are the first actuation gear, the second actuation gear, the 3rd actuation gear, 4 wheel driven moving gear, the 5th actuation gear, respectively with two axles on the first shifting gear, the second shifting gear, third gear gear, fourth speed position gear, the 5th shifting gear often meshes, reverse gear on two axles and reverse gear idle wheel often mesh, reverse gear idle wheel and jack shaft the 5th actuation gear often meshes, five drivings on described jack shaft are identical with the rotation direction of driving gear.
On two axles, being also provided with 3 cover synchronizers, is respectively at the first synchronizer between a shaftgear and the first shifting gear, at the second synchronizer between the second shifting gear and third gear gear, the 3rd synchronizer between fourth speed position gear and the 5th shifting gear; At reverse gear place, be provided with 1 sliding sleeve.Synchronizer all can replace with sliding sleeve.
Helical teeth speed variator is owing to there being axial force, the multiplex tapered roller bearing of bearing.And tapered roller bearing need to be adjusted axial clearance, be not easy to the assembling of assembly.If it is improper not adjust or adjust, bearing easily damages.In the present invention, cogged rotation direction identical (all adopting dextrorotation) on jack shaft 8, therefore on jack shaft 8, the driving gear of transmitting torque and the axial force direction of actuation gear are contrary (during engagement, jack shaft driving gear is driven gear, all the other actuation gears of jack shaft are driving gear, though so identical axial force opposite direction of rotation direction); Helix angle size by driving gear and actuation gear designs simultaneously, and the axial force of actuation gear and the axial force of driving gear are equated.Thus, two axial forces that act on the helical teeth engagement generation on jack shaft are cancelled out each other in theory, 8 bearing radial forces of jack shaft, and roller bearing 5,15 has been used in jack shaft 8 rear and front ends, has improved assembly performance and the reliability of assembly;
Centre distance is 123, and less than two jack shaft six-speed gearboxes (6DS100T) of equal moment of torsion section, the less length of volume is shorter, and single jack shaft product of comparing equal moment of torsion section also has superiority.Its applicable more chassis version (floor compartment can be lower), the layout on car load chassis is also more convenient; Forward gears is synchronizer shift, the synchronizer stroke short (11mm) of putting into gear.The synchronizer of short stroke guaranteeing shift property and in the life-span, shortening synchronizer mounting distance, for the reduction of FCL length provides condition; Sliding selector shaft 18 of the present invention is supported on clutch housing 6 and bonnet housing 12 by linear bearing 16, and the friction type of declutch shift shaft 18 motions becomes rolling friction from traditional sliding friction, and surface friction drag significantly reduces.Meanwhile, the declutch shift shaft length of general six-speed gearbox is longer, stressedly in gearshift procedure may produce larger amount of deflection when large, makes strong point place frictional force larger.Existing six-speed gearbox generally need to increase changement 29 and arrange so that have identical gear with direct drive transmission when with overdirve gear.But after increasing changement, owing to having increased manipulation link than other gear gear shift, increased more surface friction drag, thereby the berth-changing strength of overgear and adjacent gear thereof (particularly static shifting power) obviously increases.This project, for head it off, is equipped with linear bearing on reverse shift fork 17 endoporus corresponding to overgear, can significantly reduce the resistance of changement;
Current like product does not generally have pressure lubrication and forced cooling function, and under torrid areas and some extreme operating condition, speed changer heating seriously can significantly be shortened its life-span.This project is provided with oil pump 3 at jack shaft front end, one axle 1 and two axles 26 all have oilhole axially and radially, oil from oil pump enters an axle 1 from an axle radial hole, from the axial bore communicating, flow to two axles 26, between one axle 1 and two axles 26, there is transport pipe 4, from the radial hole ejection of two axles 26, lubricate corresponding spline pad and synchronizer etc. again.In addition, two oil pipes 11 and 28 are housed in housing 10, have appropriate aperture on tubing wall, the oil that oil pump is extracted out sprays meshing zone of gears territory and bearing portion through oil pipe and aperture.Meanwhile, on oil pump, leave two interfaces, before the oil of extracting out leads to above-mentioned two-way, can, by oil from this interface output, if be connected with heat exchanger, can realize forced cooling function.
On Effector, be provided with independent shift selection shaft and gear shifting rocking arm, when the control linkage of car load is single pole or single flexible axle, only need to connect the gear shifting rocking arm of described speed-changer operation device, handle gear shifting rocking arm and can realize gear selecting and gear shift; When the control linkage of car load is two bars or two flexible axle, the gear selecting leverage of car load or gear selecting flexible axle connect the shift selection shaft of described speed-changer operation device, the gear shift leverage of car load or gear-shifting flexible shaft connect the gear shifting rocking arm of described speed-changer operation device, and the action of gear selecting and gear shift separately realizes.
Specific embodiments of the invention: six-speed gearbox of the present invention has 1,2 jack shafts 8 of 1 axle and 1 two axle 26, on one axle 1 with 1 gear, on 2 jack shafts 8, there are identical driving gear, overgear (or five grades) gear, fourth speed position gear, third gear gear, the second shifting gear, the first shifting gear and reverse gear, on two axles, have the overgear corresponding with countershaft drive gear (or five grades) gear, fourth speed position gear, third gear gear, the second shifting gear, the first shifting gear and reverse gear.Meanwhile, on two axles, there are a second gear synchronizer 23,20,56 grades of synchronizers 22 of three fourth gear synchronizers and reverse gear sliding sleeve 24.Each gear on 2 jack shafts 8 is fixedly connected with jack shaft, and each gear empty set on two axles 26 is passed through spline engagement on two axles 26 and with the combination gear ring of adjacent synchronizer.So structure, has formed 6 forward gearss and 1 reverse gear.
Take 3 grades as example, three fourth gear synchronizers 20 of operation transmission are hung into third gear one side, power passes through the meshing relation of a shaftgear and jack shaft driving gear 7 from an axle input, drive 8 rotations of 2 jack shafts, jack shaft third gear gear 9 and jack shaft 8 are because be connected maintenance synchronous rotary, and then also rotation thereupon of the two axle third gear gears 21 that are engaged with, drive combination gear ring, the rotation of tooth hub of three fourth gear synchronizers 20, tooth hub and two axles 26 pass through spline joint, so power is just passed to two axles 26 by synchronizer, and then export by output flange 27.All the other power transmission lines except each forward gears of direct high by that analogy.
When hanging direct high, power, from axle 1 input, is directly exported through five or six grades of synchronizer 22-> of one shaftgear->, bis-axle 26-> output flanges 27.
When hanging reverse gear, power is from axle 1 input, through one shaftgear-> jack shaft driving gear, 7-> jack shaft, 8-> countershaft reverse gear-> reverse idler gear, 13->, bis-axle reverse gear 25-> reverse gear sliding sleeve 24-> bis-axles 26, finally also through output flange 27 outputs.
