Abstract
The utility model relates to a hydrodynamic torque-converter with small wheel base. An oil flow cycle section is formed between a turbine and a pump impeller; a torsion oscillating damper is assembled between the turbine and a locking clutch; the oil flow cycle section is an oval section which has a small end outward; the torsion oscillating damper is arranged in a space of a small end of the oval section outside the axial highest point of the turbine. The utility model designs the oil flow cycle section into the oval section with the small end outward and the torsion oscillating damper is moved outwards to the small end of the oil flow cycle section to make the torsion oscillating damper contract inwards, thereby reducing axial dimension of the hydrodynamic torque-converter, increasing a force radial of a spring in the torsion oscillating damper and improving a stress condition of the spring in the torsion oscillating damper to make the operation of the torsion oscillating damper more reliable and damper performance more excellent.
Description
Technical field
The utility model relates to a kind of fluid torque converter, relates in particular to a kind of little wheelbase fluid torque converter.
Background technique
Along with the raising of rapid development of automobile industry and people's living standard, people have higher requirement to the ease-to-operate and the ride comfort of automobile.Many high-grade cars have all disposed fluid torque converter.The automobile of configuration fluid torque converter comes transmitting torque being used for leaning on the friction clutch transmitting torque to become by hydraulic oil in the past, make the connection of power become more steady, can guarantee that vehicle starting is steady, simultaneously, guide wheel in the fluid torque converter is by the effect of overrunning clutch, the turbine starting torque is increased, increased the starting torque of automobile, and torsional vibration damper has wherein reduced the torsional oscillation of the dynamic load and the elimination power train of power train; When having little time gear shift, bigger resistance do not cause engine misses in automobile running to the minimum speed of a motor vehicle or prominent the chance yet.
The fluid torque converter of domestic production at present all is to adopt circular or oval oil stream circulation cross section, torsional vibration damper all is arranged on from the nearer place of turbine shaft, the link position of torque-converters and engine crankshaft land causes the torque-converters axial dimension bigger all at the end face of torque-converters.Because present most of car is the horizontal front wheel driving mode of motor, engine bin position vertically is less, the big fluid torque converter of axial dimension with gearbox supporting in be difficult to arrange, influenced the assembling amount of fluid torque converter on car to a great extent.
The model utility content
The purpose of this utility model is to provide a kind of little wheelbase fluid torque converter, to reduce the axial distance of fluid torque converter.
To achieve these goals, the technical solution of the utility model is to have adopted a kind of little wheelbase fluid torque converter, form an oil stream circulation cross section between turbine and the pump impeller, between turbine and blocking clutch, torsional vibration damper is installed, described oil stream circulation cross section is an egg circular section, the microcephaly of egg circular section outwardly, described torsional vibration damper is arranged in the space of the oval microcephaly side of turbine shaft beyond the peak.
Described torsional vibration damper is by the shock-absorbing spring fixed plate on the piston plate that is fixed on blocking clutch, be distributed in the spring card slot on the shock-absorbing spring fixed plate, shock-absorbing spring that clamps in the spring card slot and torque transmission plate constitute, and the torque transmission plate is fixed on the back side of turbine and is between adjacent two spring card slots.
Fixing screw member is fixedly installed on the periphery front end of pump impeller protecgulum on the pump impeller protecgulum.
Described screw member is an annular land, evenly is provided with the screw more than three or three on the annular land in a circumferential direction.
The utility model becomes oval to oil stream circulation Cross section Design, and, makes torsional vibration damper move to microcephaly's side in oil stream circulation cross section outward simultaneously with ovate microcephaly outwardly, can make receipts in the torsional vibration damper, thereby reduce the axial dimension of fluid torque converter.Simultaneously, torsional vibration damper is moved outward, also increased the active force radius of torsional vibration damper medi-spring, improved the force-bearing situation of torsional vibration damper medi-spring, make torsional vibration damper work more reliable, damping property is better.In addition, the screw member on the pump impeller protecgulum is moved to the front end of the periphery of pump impeller protecgulum outward, also can abdicate the oneself height of spiral shell seat, further reduce the axial dimension of torque-converters.The pump impeller protecgulum of torque-converters is connected with the bent axle land with bolt by the screw member that the annular land that welds on its periphery constitutes, not only reduced the axial dimension of fluid torque converter, and increased the area of contact of fluid torque converter and engine crankshaft land, make the connection of fluid torque converter more reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
As Fig. 1, shown in Figure 2, form oval oil stream circulation cross section between the turbine 9 of little wheelbase fluid torque converter of the present utility model and the pump impeller 10, between turbine 9 and blocking clutch 3, torsional vibration damper is installed, the microcephaly of egg circular section outwardly, torsional vibration damper is arranged in the space of the oval microcephaly side beyond the turbine 9 axial peaks, torsional vibration damper is by the shock-absorbing spring fixed plate 2 on the piston plate 1 that is fixed on blocking clutch 3, be distributed in the spring card slot 7 on the shock-absorbing spring fixed plate 2, shock-absorbing spring 4 that clamps in the spring card slot 7 and torque transmission plate 8 constitute, torque transmission plate 8 is fixed on the back side of turbine 9 and is between adjacent two spring card slots 7, fixing screw member is fixedly installed on the periphery front end of pump impeller protecgulum on pump impeller 10 protecgulums, the screw member is an annular land 5, evenly is provided with six screws 6 on the annular land 5 in a circumferential direction.
