Description
What three two hearts of the utility model, six speed automobile speed changers related to is a kind of new automobile speed-changing gear box, is specially adapted to various automobile and various dynamic power machine.
At present automotive transmission be a perfect structure since over half a century in the world, but still not compact, volume greatly, longitudinal ruler modest ability, the scale of construction be big.Cluth re-building need be pulled down speed changer, has increased the weight of the degree of difficulty of repairing.Clutch in the automobile gearbox be the most fragile in the chassis, the project that the most often needs repairing this; it also is one of maintenance items of comparatively difficulty; clutch friction plate is the low priced and easily worn articles; because of wearing and tearing significantly or burning out; can cause automobile to travel; this is the automobile common disease, takes place through regular meeting.Want the repair and replacement clutch and more renewal of facing renewal must unload gearbox, its labor intensity is big, man-hour many, maintenance operation difficulty, particularly trouble more in transit.
The purpose of this utility model provides a kind of novel three two hearts six speed or five speed automobile speed changers, key is the special construction that planetary gear system, overdrive clutch device and gear reversing device are installed on jack shaft, make compact structure, the physical dimension and the weight of speed changer have been significantly reduced, can unload gearbox and directly keep in repair clutch, change its friction plate, the maintenance of easy automobile clutch and installation.
Three two heart six speed automobile speed changers take following scheme to realize: speed changer has gearbox casing, first of speed changer is housed in the casing, first has spline, driving gear and spline engagement, locate by screw, tail end has screw, screws in so that backward by extracting out in second the hole in order to special-purpose stay bolt.Second is installed in first rear portion is hollow shaft, with first be same axle center, be fixed with two gears on second, or be connected as a single entity with axle, handle reverse gear mechanism and be installed in second outside, planetary gear system and free wheel device are installed on the jack shaft, and output power is installed on the jack shaft with gear.
Three two heart six speed automobile speed changers are a kind of new automobile speed-changing gear boxs, and this gearbox designs key is to be equipped with on the jack shaft special construction of planetary gear system, overdrive clutch device and gear reversing device, handle reverse gear and are positioned at outside second with mechanism.This speed changer structure compactness has significantly reduced the physical dimension of speed changer, and especially the length of second and jack shaft can increase the rigidity of axle greatly, and reduce amount of deflection, can reduce the wearing and tearing and the damage of gear and other pieces, and weight also alleviates simultaneously.Can unload gearbox and directly keep in repair clutch, the maintenance of easy greatly automobile clutch and installation.Can eliminate the corresponding many faults that cause because of frequent dismounting speed changer.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is three two hearts, six speed automobile speed changer structure schematic representation.
With reference to accompanying drawing, three two hearts, six speed automobile gear graduation box structures are: have gearbox casing, first (1) spline engagement driving gear (2) of gearbox; Locate by screw (28); Tail end has one of screw, screws in order to special-purpose long screw, so that backward by extracting first out in second axis hole.Second hollow, be connected as a single entity with one of gear (4) or gear (11); Another gear then key connects second with fixing.Driving gear (2) often is meshed with gear (27) on being fixed on jack shaft (12), for a pair of fixedly helical gear right.Be swaged into the gear (17) of one with jack shaft, be the driving gear Za of planetary gear system.Planetary pinion (19) is planetary gear system ZH, three～four.Ring gear (23) is planetary gear system Zb; Its anterior overdrive clutch device (21) of installing can be meshed with gear (26), is used for transmitting reverse gear power; There is stopping gear (22) its outer ring, often is meshed with gear ring (7), and is used for advancing.Planetary carrier (20) also is equipped with stopping gear (18), often is meshed with gear ring (9), and is used for moveing backward.Handle the gear ring (7) of reverse gear mechanism and gear ring (9) and slide (rolling) respectively and move in sky and be enclosed within second outside, be fixed on the casing, the motionless fixed block (10),, fix by nut (5) by fixed block (6).Reverse gear is contained between gear ring (7) and the gear ring (9) with fit device (8), and at ordinary times, promptly during reset condition, fit device (8) often is meshed with gear ring (7).Gear (16) rolls and is installed on the jack shaft, is meshed with second cog (11).Output power is fixed on the jack shaft with gear (13).
The work embodiment of three two heart six speed automobile speed-changing gear boxs (with reference to accompanying drawing) is: move behind gear gearing device (24), with planetary carrier front end gear engagement, then engine power advances first grade through gear (2), (27), (17), (19), planetary carrier (20), gear gearing device (24), gear (26) and gear (4) formation.When gear fit device (15) reach, with planetary carrier rear end gear engagement, then engine power constitutes and advances second grade through gear (2), (27), (17), (19), planetary carrier (20), gear fit device (15), gear (16) and gear (11).When gear fit device (24) reach, with gear (25) engagement that is fixed on the jack shaft, then engine power constitutes the third gear of advancing through gear (2), (27), (25), gear gearing device (24), gear (26) and gear (4).Gear fit device (3) reach is directly meshed with driving gear (2), constitutes advance fourth speed, i.e. direct high.Move behind the gear fit device (14), mesh with gear (13), constitute and advance the 5th grade with output power.Move behind the gear fit device (8), disengage from gear ring (7), and move after continuing, be meshed with gear ring (9), then engine power constitutes reverse gear through gear (2), (27), (17), (19), ring gear (23), free wheel device (21), gear (26) and gear (4).Fit device (8) is when moving forward and backward, and with gear ring (7), (9) engagement, its end face has friction brake wafer, in order to gear shift.
The automobile gear gearbox of three two heart six speed, first of having branch to be situated between; Hollow second, and special reverse gear control mechanism; Planetary gear system and overdrive clutch device are installed on the jack shaft.This gearbox is suitable for all kinds of automobiles, and dynamic power machine.The automobile gear gearbox is located to simplify at gear (26), and cancellation gear (25) and respective members can be arrogated to oneself the automobile gear gearbox that becomes three two hearts, five speed (four speed of advancing).Still belong to three two hearts of the utility model, six speed automobile speed-changing gear box categories.The automobile gear gearbox is on light-duty vehicle, consider that volume and weight are all little, during the still dismantled and assembled gearbox of maintenance clutch, or consider that running environment well, more renewal of facing renewal, maintenance clutch are seldom ignored first variation is arranged, still during the dismounting gearbox, can cancel that first branch is situated between and second hollow, and thereupon other also change and cancel.Still belong to three two hearts of the utility model, six speed automobile speed-changing gear box categories
