In radially inner side and the stage casing of fluid torque-converter 1, compare existing known fluid torque-converter, it need not design self-contained piston part, thus reduces the axial dimension of device;Radial outside in fluid torque-converter 1, torsion vibration absorber assembly 60 is contained in axial space between lock-up clutch 50 and the pump cover 11 directly over turbine shroud 31 radial direction, it is less than turbine shroud 31 in axial forward direction, the axial dimension equally reducing fluid torque-converter 1 to a great extent.Therefore, the fluid torque-converter 1 of the present invention more they tend in the axial direction compact.

Additionally, this fluid torque-converter 1 can be directly connected to pump impeller housing 21 and turbine shroud 31, when lock-up clutch 50 combines, pump wheel assembly 20 is mechanically connected with turbine assembly 30, forms turbine amortisseur, and its damping performance is more preferable than prior art individual pen amortisseur performance.

The top half along axis of the fluid torque-converter sectional view involved by second embodiment of the present invention is shown in Fig. 2.It is had differences with the internal structure of the fluid torque-converter of first embodiment, thus driven disc 63 is adjusted to and is connected to output flange 65 by rivet 64 in front.The fluid torque-converter internal structure layout of this type so can be better conformed to.

Will be detailed below the work process of fluid torque-converter 1.In vehicle start, under the operating modes such as shift speed change, fluid torque-converter 1 annular space between oil pump support shaft 80 and transmission input shaft 70 is constantly filled with certain pressure work fluid to torus t, form the release oil circuit r of lock-up clutch 50, under the high-voltage oil liquid effect in release oil circuit r, lock-up clutch 50 is pushed to front and discharges completely, motor torque passes through pump cover assembly 10 and pump wheel assembly 20 transmits torus t, through the effect output of torus t fluid power to turbine assembly 30, it is input to transmission input shaft 70 through torsion vibration absorber assembly 60 again, now engine luggine is completely by the fluid power effect isolation of torus t.

Fluid torque-converter 1, when lock-up clutch 50 discharges, leads to the overall transmission efficiency of fluid torque-converter 1 low due to the fluid power effect of torus t, during operating mode therefore generally beyond vehicle start and shift speed change etc. combines lock-up clutch 50.Now fluid torque-converter 1 is constantly filled with certain pressure work fluid between turbine 32 and pump cover 11 in the center in the hole of transmission input shaft 70, form the combination oil circuit a of lock-up clutch 50, with reference under the high-voltage oil liquid effect in oil circuit a, lock-up clutch 50 is pushed to rear and combines, pump wheel assembly 20 is mechanically connected with turbine assembly 30, motor torque passes through pump cover assembly 10, pump wheel assembly 20, lock-up clutch 50 and turbine assembly are transferred to torsion vibration absorber assembly 60, through damping spring 62 effect output to output flange 65 and transmission input shaft 70, engine luggine is weakened by torsion vibration absorber assembly 60 completely.

In lock-up clutch 50 cohesive process, for avoiding the unexpected enormous impact combining and producing, by controlling with reference to the oil liquid pressure that works in oil circuit a, make lock-up clutch 50 be first in slipping state, then be transitioned into and be completely combined.

As above with reference to the accompanying drawings the specific embodiment of the present invention is described in detail.Those skilled in the art can carry out equivalent remodeling or modification to feature specific in embodiment according to the above description.Certainly, the embodiment that these change also will fall in the protection domain that claims are covered.
