Description
Technical field
The present invention relates to a kind of gear drive, but particularly a kind of mechanical transmission of preliminary election shelves.
Background technique
Speed changer is the gear drive that can fix or change output shaft and input shaft velocity ratio; Speed changer on the automobile is through changing velocity ratio; Change the torsion of engine crankshaft; To adapt to,, be one of topmost parts in the automotive transmission to the needs of driving wheel tractive force and speed of a motor vehicle demands of different starting to walk, quicken, go and overcome under the different driving conditions such as different kinds of roads obstruction.Car gear shifting mechanism generally is handsetting gear or other engage a gear mechanisms at present, makes former a certain gear pair with gear throw off transmission, makes the gear pair entering work of another gear again; But all necessary let slip the clutch before gear shift; Interrupt power transmission, be convenient to make the engagement pair of former gear to throw off, make the speed at the engagement position of new gear engagement pair progressively tend to synchronous simultaneously; This is tending towards synchronous process need waste certain hour from interrupting power transmission to new gear, has expended oil mass simultaneously again.In order to make in the gearshift procedure; The power of motor constantly is passed on the wheel all the time; Realize separated continuously gear shift, adopt double-clutch speed changer usually, but the clutch system of double-clutch speed changer is when switch clutch; Because the frictional force of clutch needs an of short duration time from zero increase, therefore can't accomplish thoroughly continuously at a distance from gear shift.Again because double-clutch speed changer is to adopt friction driven system, limit by frictional force can not transmitting large torque, and heating value height, easy abrasion.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of can be continuously at a distance from the speed changer of gear shift and transmitting large torque.
Technological scheme of the present invention is following: but a kind of mechanical transmission of preliminary election shelves; Comprise housing (1), input shaft (2) and output shaft (3), the afterbody of said input shaft (2) stretches in the housing (1), is set with input gear (15) at the afterbody of this input shaft (2); On said output shaft (3), be set with output gear; In said housing (1), be provided with two groups of epicyclic gear trains, two groups of epicyclic gear trains include sun wheel shaft (4), planet wheel (5), gear ring (6) and planet carrier (7), and said sun wheel shaft (4) is passed through bearings in housing (1); This sun wheel shaft (4) gear (16) is connected; On the axle body of said sun wheel shaft (4), also be set with sun gear (4a), this sun gear (4a) is meshed with planet wheel (5), and said planet wheel (5) is sleeved on the head of planet carrier (7); In housing (1), this gear ring (6) has internal tooth (6a) and external tooth (6b) to said gear ring (6) through bearings, and said gear ring (6) is meshed with input gear (15) through external tooth (6b), and this gear ring (6) is meshed with planet wheel (5) through internal tooth (6a); Afterbody at planet carrier (7) is set with counter shaft gear, and this counter shaft gear is meshed with output gear.
The present invention is when working at ordinary times; Wherein the sun wheel shaft of one group of epicyclic gear train (4) is controlled its rotating speed by gear (16); Making its degrees of freedom is zero, thereby makes this epicyclic gear train become planetary gear train, passes to the gear ring (6) of current line star wheel series through input gear (15) from the moment of torsion of input shaft (2) input; Pass to planet wheel (5) by gear ring (6) again; Through planet wheel (5) moment of torsion is passed to planet carrier (7) then, pass to output gear via counter shaft gear again, pass to output shaft (3) at last and drive slave equipment work.The sun wheel shaft of other one group of epicyclic gear train (4) keeps free rotary state, thereby makes this epicyclic gear train become differential gear train, and power can't pass to output shaft (3) via current differential gear train from input shaft (2).When gear shift; Remove the state of a control of the sun wheel shaft (4) of this epicyclic gear train with the gear (16) that just links to each other in the epicyclic gear train of transferring power; Make the sun wheel shaft (4) of this epicyclic gear train transfer free rotary state to, thereby make this epicyclic gear train become differential gear train, can't transferring power; Simultaneously, the sun wheel shaft of another epicyclic gear train (4) is controlled its rotating speed through gear (16), thereby makes this epicyclic gear train become planetary gear train, and power is passed to output shaft (3) from input shaft (2) via the counter shaft gear of suit on this planetary gear train.Owing to carry out gear shift through gear drive; Need not realize through clutch; Saved the time that frictional force increases, saved the process of engagement again that is out of gear again, so shift time can ignore compared to traditional speed changer; The power that has guaranteed motor constantly is passed on the wheel all the time, has realized continuously at a distance from gear shift.Simultaneously, because the gear type gear shift of adopting, can transfer larger torque, and reduced the heat that clutch friction produces.
On said output shaft (3), be installed with first output gear (21), second output gear (22), the 3rd secondary output gear (23) and the 4th output gear (24) successively; Be provided with axle sleeve (10) between two adjacent output gears, this axle sleeve (10) is sleeved on the output shaft (3); On the planet carrier (7) of two said epicyclic gear trains all successively kink first counter shaft gear (17), second counter shaft gear (18), the 3rd counter shaft gear (19) and fourth officer shaftgear (20) are arranged; First counter shaft gear (17) of two epicyclic gear trains all is meshed with first output gear (21); Second counter shaft gear (18) of two epicyclic gear trains all is meshed with second output gear (22); The 3rd counter shaft gear (19) of two epicyclic gear trains all is meshed with the 3rd output gear (23), and the fourth officer shaftgear (20) of two epicyclic gear trains all is meshed with the 4th output gear (24); On the planet carrier (7) of two said epicyclic gear trains, all be set with two synchronizers (9); First synchronizer (9) is positioned between first counter shaft gear (17) and second counter shaft gear (18); Second synchronizer is positioned between the 3rd counter shaft gear (19) and the fourth officer shaftgear (20), and four said synchronizers (9) all link to each other with shifting fork mechanism.At synchronization, there is and only have a counter shaft gear to be fixedly linked on the planetary gear train through synchronizer (9) and planet carrier (7), there is a counter shaft gear to be fixedly linked on the differential gear train at most through synchronizer (9) and planet carrier (7).Before the needs gear shift, shifting fork mechanism is stirred synchronizer (9), and the counter shaft gear that needs to use on the planet carrier of current differential gear train is solidly set on planet carrier (7) in advance, chooses gear in advance, and then carries out gear shift.Because all have four counter shaft gears to be meshed with four output gears on the output shaft on two epicyclic gear trains, the present invention can be switched arbitrarily between eight transmission speed ratios, has improved practicability of the present invention.
