Abstract
The utility model relates to a hydrodynamic torque-converter. A torsion oscillating damper is assembled between a turbine and a locking clutch; the torsion oscillating damper is arranged outside the axial highest point (a) in the back of the turbine of an oil flow cycle section. As the torsion oscillating damper is moved outwards radially, stress of the torsion oscillating damper decreases make a damper spring of the torsion oscillating damper dapper and flexile, thereby improving damper performance and life-span of the damper spring. The design and the design of an oval oil flow cycle section which has a large end inward can shorten axial dimension of a torque converter, thereby being convenient for installation and application of the torque converter in front-wheel-drive cars; a screw base on a front cover of a pump impeller is fixed on a peripheral end of the front cover of the pump impeller, thereby shortening the axial dimension of the torque converter further and being more beneficial for popularization and application of the utility model.
Description
Technical field
The utility model relates to a kind of 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 turbine shaft that the turbine of existing fluid torque converter and the torsional vibration damper between the blocking clutch all are arranged on oil stream circulation cross section to peak with interior from the nearer position of turbine shaft, in this design, because vibration damper is nearer from rotating shaft, the torsional moment that is subjected to is bigger, make shock-absorbing spring increase in the car compressive force that is subjected in service thereupon, this just need make shock-absorbing spring a little louder to increase its elasticity coefficient, do the damping property that causes torsional vibration damper on the contrary like this and descend, and accelerate the speed of its fatigue damage.
The model utility content
At the problems referred to above, the purpose of this utility model is to provide a kind of fluid torque converter, so that the damping property of torsional vibration damper increases.
For achieving the above object, the technical solution of the utility model is to adopt a kind of fluid torque converter, be equipped with torsional vibration damper between turbine and the blocking clutch, this torsional vibration damper is installed in the position in addition, the turbine back side axial peak (a) in oil stream circulation cross section.
The shock-absorbing spring fixed plate of described torsional vibration damper is fixed on the piston plate of blocking clutch, the power transmission baffle plate is fixed on the turbine back side, be separately installed with shock-absorbing spring in each spring groove on the shock-absorbing spring fixed plate, above-mentioned power transmission baffle plate is between the two adjacent spring grooves.
Described oil stream circulation cross section is an oval cross section, and the major part of oval cross section inwardly.
Screw on the described pump impeller protecgulum evenly is arranged on the periphery front end of pump impeller protecgulum.
Because the torsional vibration damper footpath is outwards moved, make the stressed decline of torsional vibration damper can make the shock-absorbing spring of torsional vibration damper manufacture comparatively small and exquisitely and pliable and tough, improve the working life of damping property and shock-absorbing spring.Major part avette oil stream circulation Cross section Design is inwardly added in this design, can reduce the axial dimension of torque-converters again, help installation and the application of this torque-converters on f-w-d car, spiral shell seat on the pump impeller protecgulum is fixed on the periphery front end of pump impeller protecgulum, can further reduce the axial dimension of torque-converters, help of the present utility model applying more.
