The specific embodiment
For helping those skilled in the art can understand definitely the claimed theme of the present invention, below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail.
Fig. 1 is the lever method sketch of the automatic transmission planetary gear system that the present invention relates to.This structure is comprised of three rows of planetary rows, by 5 power-transfer clutchs are carried out to different combinations, controls, and realizes different transmitting ratio requirements.Fig. 2 illustrates for the gearshift situation that the various combination by power-transfer clutch is realized the automatic transmission with hydraulic torque converter the present invention relates to.The present invention can be used for any parking situation, is particularly useful for parking situation when ramp is best is upward slope.
In conjunction with Fig. 1, the sun and planet gear of described automatic transmission with hydraulic torque converter comprises the first epicyclic gear train, the second epicyclic gear train and third planet gear row, each epicyclic gear train includes sun wheel, satellite gear and gear ring, i.e. the first sun wheel S1, the first row star-wheel C1 of the first epicyclic gear train and the first gear ring R1, the second sun wheel S2 of the second epicyclic gear train, the second satellite gear C2 and the second gear ring R2, and third planet gear row's the 3rd sun wheel S3, the third line star-wheel C3 and the 3rd gear ring R3.In Fig. 1, using each gear to draw as node.In addition, five power-transfer clutchs are respectively first clutch CB1234, second clutch CB26, the 3rd power-transfer clutch C456, four clutches C35R and the 5th power-transfer clutch CBLR, and they are all bidirectional clutches.As seen from the figure, input shaft Tin connects the second sun wheel S2, by the 3rd power-transfer clutch, be connected with the first row star-wheel C1 simultaneously, and be connected with the first sun wheel S1 by four clutches, when the 3rd power-transfer clutch in conjunction with time, input shaft Tin connects the first row star-wheel C1, and when the 3rd throw-out-of clutch, input shaft Tin is separated with the first row star-wheel C1; When four clutches in conjunction with time, input shaft Tin connects the first sun wheel S1, when four clutches is thrown off, input shaft Tin separated with the first sun wheel S1 (principle of work of following first clutch, second clutch and the 5th power-transfer clutch is identical with four clutches with the 3rd power-transfer clutch, will not repeat).The opposite side of the first sun wheel S1 is connected with automatic transmission with hydraulic torque converter (as casing) by second clutch, and the first row star-wheel C1 is also connected with the second gear ring R2 by free-wheel clutch F1, and also by the 5th power-transfer clutch, is connected with automatic transmission with hydraulic torque converter (as casing).The second satellite gear C2 connects the 3rd gear ring R3, and the third line star-wheel C3 connects output shaft Tout, and the 3rd sun wheel S3 is connected with automatic transmission with hydraulic torque converter (as casing) by first clutch.The effect of free-wheel clutch F1 is under a gear state, makes vehicle realize wheel function, and output shaft Tout rotating speed can be counted ratio divided by a gear over input shaft Tin rotating speed.Under this operating mode, vehicle keeps the higher speed of a motor vehicle to slide, but engine speed can maintain compared with slow speed of revolution.
The gear locking operating mode of take is example, when in this operating mode, and power-transfer clutch CB1234(first clutch) and CBLR(the 5th power-transfer clutch) combination, making accordingly the 3rd sun wheel S3 and the second gear ring R2 is that rotating speed is zero by locking.So when input shaft Tin has forward rotational speed Nin, the second sun wheel S2 has forward rotational speed Nin, the rotating speed of the second satellite gear C2 is Nin * (R2C2)/(R2S2)=Nin * Z
s2/ (Z
r2+ Z
s2), Z wherein
s2be the second sun wheel number of teeth, Z
c2it is the second gear ring number of teeth.Same reason, it is output shaft rotating speed that the rotating speed of the second satellite gear C2 can be converted into C3 on the third line star-wheel C3:
Nout?=?Nin×Z
S2/(Z
R2+Z
S2)×Z
R3/(Z
R3+Z
S3)；
The transmitting ratio that has produced thus a gear is:
Nin/Nout?=?1/[Z
S2/(Z
R2+Z
S2)×Z
R3/(Z
R3+Z
S3)]。
When vehicle parking, now the 3rd power-transfer clutch and the first row star-wheel C1, four clutches and the first sun wheel S1, the 5th power-transfer clutch and the first row star-wheel C1 throw off respectively, and free-wheel clutch F1 is combined with the first row star-wheel C1 or the second gear ring R2.As now second clutch and the first sun wheel S1 throw off, the first sun wheel S1 is in free state, the first row star-wheel C1 is because free-wheel clutch F1 can only one-way movement (being rotated in the forward), and the first sun wheel S1 not limited causes that the first gear ring R1's is not limited.For example, while going up a slope in ramp, Action of Gravity Field can cause vehicle rollback, and then what make that output shaft Tout does is the motion of contrarotation (being in reverse to first direction D1).As now second clutch and the first sun wheel S1 are combinations, the sun and planet gear that the present invention under this mode of operation shown in Figure 3 relates to, the relative automatic transmission with hydraulic torque converter of the first sun wheel S1 is fixed, because the first row star-wheel C1 due to free-wheel clutch F1 can only be unidirectional be rotated in the forward (and being to make vehicle towards the first direction D1 motion of advancing), the first gear ring R1 can keep motion in the same way with the first row star-wheel C1.Vehicle can only advance under this operating mode, can not retreat, thereby realize upward slope automatic parking function.Once input shaft Tin obtains torque, output shaft Tout can start to walk and move with first direction D1.
Fig. 4 has provided the schematic flow sheet of concrete control logic.When vehicle brakes static operating mode from normal driving operating mode, gearbox controller monitors 1) gear shift lever position is D, 2) speed of a motor vehicle is zero, 3) Das Gaspedal unclamps, and simultaneously 4) brake pedal is when be operated, and enter automatic parking function and control.Wherein the 5th) condition is the time conditions for postponing, and prevents from causing that because signal disturbs erroneous judgement is disconnected.Preferably time length t is greater than Preset Time threshold value t
0after, automatic parking function on, gearbox controller sends instruction and makes its combination to second clutch is oil-filled, more preferably, threshold value t
0it is 0.5 second.Due to the kinematic relation of change-speed box planetary gear train, make vehicle at this moment can not have the movement of direction of retreat.When automatic parking function on, continue each signal of monitoring, when shift signal does not keep off at D, or vehicle speed signal is non-vanishing, or when throttle signal is non-vanishing, show that chaufeur has started to drive vehicle to move forward, at this moment exit automatic parking state of a control, return to the master mode of normal operation.Controller sends instruction to second clutch draining, gets back to normal driving operating mode.When entering automatic parking functional mode, be consistent with the clutch state of the gear of 2 in Fig. 2.
The planetary structure of upward slope automatic parking function of the present invention based on this six speed transmission realized, and designs ingeniously, and cost is low, and alternative auxiliary electron brake system completes upward slope automatic parking function.This invention can be used for being equipped with on this change-speed box and the vehicle with start-stop function (Start/Stop) equally, and its effect is more obvious.
Although at length illustrate and described specific embodiments of the invention so that principle of the present invention to be described, it should be understood that the present invention can embodied in other and do not depart from such principle.
