Background technology
The two tween drive shaft Automotive transmissions of producing both at home and abroad more than six grades are major and minor pair of body structure formula at present, and wherein main tank is gear change-speed box more than (being generally 4,5 or 6 grades), and odd-side is a two-speed transmission, and main tank is with or without synchro; Odd-side all adopts synchronizer shift, and electricity consumption or gas manipulation, generally speaking, its power transmission line is: engine power passes in the main tank, passes to tween drive shaft by the engagement of a shaft gear and tween drive shaft transmission gear, again to the gear of two corresponding gears, pass to two by shift sleeve again, driven wheel by odd-side passes to the odd-side tween drive shaft then, arrives the corresponding shifting gear of odd-side again, and power is exported by the odd-side main shaft with combining of odd-side gear by the odd-side synchronizer gear sleeve.This pair casing change-speed box power transmission line is longer relatively, and structure is comparatively complicated, and its fault rate also increases relatively, and the manufacturing cost height directly has influence on the manufacturing cost of automobile.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and provide a kind of pair of tween drive shaft list casing Automotive transmission, that is to say the odd-side that takes down in the former Automotive transmission, the integral structure of its main tank is done one improve, making it can satisfy engine output is the change-speed box that various autotruck about 191KW-228KW or speciality car require.
This purpose realizes with following technical proposal: this Automotive transmission is two tween drive shafts, single body structure formula.Mainly include one in the casing, be connected with two at an end of one, two two ends are respectively equipped with fixed type bearing, one side bearing is captiveed joint with a shaft end, other end bearing fixing is on casing, and an end of two is a mouth, its direct connection propeller-shaft.There are two identical and symmetrical tween drive shafts two both sides, and there is fixed type bearing at the two ends of every tween drive shaft.One is provided with a shaft gear, is respectively arranged with corresponding transmission gear, the wherein engagement of the transmission gear on a shaft gear and the tween drive shaft on two tween drive shafts and two; All the other gears on the tween drive shaft and two upward corresponding each grade gears mesh.Going up between per two grades of gears for two has sliding sleeve, and shift fork is arranged on the sliding sleeve, and declutch shift shaft is connected with shifter bar.Described two be diameter do not wait stepped.Operative gear on the described tween drive shaft is to be made of the axle tooth on middle axis body and the axis body.
The utlity model has following advantage: it is simple for structure, compact, and power transmission line is very brief; Many intermediate links have been reduced; Easy to operate, dependable performance have improved machinery driving efficiency widely; Easily processing and manufacturing, installation and maintenance are convenient; Dwindle the change-speed box volume greatly, reduced cost; Can satisfy engine power is the various autotrucies of 191KW-228KW and the requirement of speciality car.
Description of drawings
Fig. 1 is axial principal section structural representation of the present utility model (wherein having omitted a countershaft assembly and original reverse gear idle wheel part).
The specific embodiment
In conjunction with the accompanying drawings integral structure of the present utility model and working process are made a detailed description:
As shown in Figure 1, this Automotive transmission is two tween drive shaft list body structure formulas.Mainly include one 1 in the casing, it is captiveed joint with casing by bearing, and two 10 devices are at one right-hand members, and is connected with one by bearing 2, and two right-hand member is captiveed joint with casing by bearing 11.Two 10 is stepped, and left side section diameter is less than right section diameter (being to design in order to dwindle the change-speed box volume).Two right-hand members are mouth, and it is by flange 17 direct connection propeller-shafies.Two 10 lengthenings in the design, device has seven transmission gears (seven class are promptly arranged) thereon, and it satisfies the automobile variable speed of seven speed.At two 10 both sides devices two identical tween drive shafts 14 are arranged, and symmetrically, this tween drive shaft is captiveed joint with casing by the bearing at two ends.At a right-hand member device one shaft gear 3 is arranged, transmission gear 12 engagements of it and tween drive shaft left end.On the tween drive shaft 14 device all the other gears with two 10 on the corresponding one by one engagement of each (shelves) gear, shown in Fig. 1 is seven speed transmission, seven transmission gears are arranged on two, and each gear (is example with six shift of gears 6) is connected with two 10 by gear adjusting pad 7, two shaft gear spline pads 8, locating ring 9.This gear has certain amount of floating at radial direction, in order to the processing that compensates two countershaft-gears, in installing error is arranged and two skews of going up each (shelves) gears producing, makes gear meshing smooth-going, does not have the rigidity interference; On the tween drive shaft four gears of left side section all by big interference by singly-bound and firm the linking together of tween drive shaft, four gears 15 of right section are directly processing tooth formation on tween drive shaft, so, further dwindle the change-speed box volume.Go up between per two (shelves) gears for two sliding sleeve 4 is housed, shift fork 5 is housed on the sliding sleeve, shift fork is contained on the declutch shift shaft, and declutch shift shaft 16 passes through original steering unit and is connected with shifter bar on the automobile.
Manipulation of the present utility model and working process: in the driving process, after the driver plucked shelves, each other parts of change-speed box were the position shown in the accompanying drawing 1.Passed to power one spool 1 on by driving engine, power-transfer clutch this moment, passes on the shaft gear 3 through invoice serration again, and a shaft gear 3 is meshed with tween drive shaft transmission gear 12, and power passes on the tween drive shaft 14, and each gear rotates with tween drive shaft on the tween drive shaft.Each gear of tween drive shaft drives corresponding each (shelves) gear rotation on two 10 again, because each grade gear is in Neutral Position, so two last each grade gears also are in idling conditions, two 10 no power takeoffs.
When driver's engage a gear (is example to hang six grades), handle the joystick in the operator's compartment, making six or seven grades of declutch shift shafts drive six or seven grades of shift forks 5 through speed change leverage steering unit axially moves to left, the fork pin of shift fork promotes two sliding sleeves 4 again and moves axially, the male splines of two sliding sleeves combines (it is combination commonly used in the prior art) with the female splines of the 6th (shelves) gear 6, whole engage a gear process is finished smoothly.Like this, when power through driving engine, power-transfer clutch by after one 1 input, pass on the shaft gear 3 by spline, pass to the tween drive shaft transmission gear 12 of two one-tenth symmetrical mountings again, pass to sliding sleeve 4 on two 10 by spline engagement, afterwards, two 10 output power by gearbox output flange 17.Because this Transmission gear is more, speed ratio is differential less relatively between each grade, so the speed discrepancy between each grade is also less when working; Same as the prior art in addition is combining of two sliding sleeves and gear (for example sliding sleeve 4 and gear 6), and the oblique angle α of identical size is arranged in the tooth end; And two shaft gear on two, be in quick condition, so, when gear shift in conjunction with the time can make framing member play certain auto-centering and synchronous effect.
The design's unitary construction makes width between centers reduce, gear width attenuate, and axial dimension shortens, and quality alleviates, and just must install in the layout of automotive transmission; Handle lightly, gearshift is simple in structure.
