る。The present invention relates to a torque converter provided in a power train between an internal combustion engine and a transmission, and a direct clutch between the turbine wheel and the pump wheel. Related to automobiles. 2. Description of the Related Art In a device of this type, vibration is attenuated or cut off at a low rotational speed via a torque converter. In order to save energy, the torque converter is short-circuited after a certain number of revolutions via the direct coupling. To dampen noise or torque shocks, a torque damper is generally incorporated in the direct coupling, which permits a very large pivot angle. This type of device presents special problems during the load exchange operation, which results in transmission noise and vibrations of the entire drive train. The problem to be solved by the invention is to reduce this kind of noise and vibration. Means for Solving the Problems The gist of the present invention that has solved the above problems is that, when viewed from the direction in which power is transmitted from the internal combustion engine, a rim with a starting tooth engaged with a crankshaft provided following the internal combustion engine is provided. The vibration damper is arranged between the flywheel having the flywheel and the cover of the torque converter which is closer to the internal combustion engine, and the torque converter direct coupling clutch is configured as a direct coupling clutch having no vibration damper. It is in. The cover or casing of the torque converter then effectively forms the input of the torque converter. In other words, the cover or casing is connected to the pump wheel of the torque converter. In one embodiment of the invention, a vibration damper provided between the flywheel and the pump wheel has damping that is controlled or adjusted depending on the centrifugal force. In another embodiment of the invention, the vibration damper is lockable. In this case, the vibration damper is locked after a predetermined number of revolutions, for example, approximately 2500 to 3000 γ · P · m. According to the device of the present invention, vibration and noise at the time of load exchange are reduced, and the structure of the direct coupling clutch is simplified. In addition, the connection between the flywheel and the input portion of the torque converter after a predetermined rotation speed is obtained. A fixed connection between them is obtained. The advantage of the latter is that
At high rotational speeds, there is no wear phenomenon on the energy storage device and the members to which the energy storage device engages. With this centrifugal direct coupling, the vibration damper is locked in a rotational speed range which is no longer technically necessary. This adjusts the operating function and eliminates the dangerous wear that would otherwise occur in this operating state. In a particularly advantageous embodiment of the invention, the vibration damper has two inputs and one output, the two plate-shaped inputs being separated radially inside the energy storage by means of a separating element. The output part which is connected to the flywheel and is located therebetween is fixed to the cover of the torque converter radially outside the energy storage device. In another embodiment of the centrifugal direct coupling of this vibration damper, a flyweight with a friction lining is fixed to the input of the vibration damper and extends in the axial direction at the output of the vibration damper. It is opposed to the wall. In this case, the flyweight abuts the wall after a predetermined number of revolutions, whereby the input and output of the vibration damper are connected to each other. This bond becomes progressively stronger, in other words, fixed. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A flywheel 1 fixed to a crankshaft (not shown) has a rim 2 with starting teeth and supports plate-like input portions 4 and 5 of a vibration damper 8 via bolts 3. The vibration damper 8 is composed of the flywheel 1 of the torque converter 7 and the cover 6.
And is located between. The output 9 of the vibration damper 8 is arranged in the axial direction between the two inputs 4, 5, which is connected to the cover 6 of the torque converter 7. Between the input units 4, 5 and the output unit 9 of the vibration damper 8,
An energy storage device 10 in the form of a coil spring and a friction device in the form of friction linings 11, 12 are arranged. The cover 6 of the vibration damper 7 is fixedly connected to the pump wheel 13 of the torque converter. A conventional torque converter directly connected clutch between the turbine wheel 14 of the torque converter 7 and the cover 6.
The torque converter direct-coupled clutch fixedly couples the pump wheel 13 and the turbine wheel 14 to each other at a high rotational speed. The vibration damper 8 is a direct coupling clutch that depends on the centrifugal force.
Has 16 The direct connection clutch 16 includes a corrugated leaf spring member 18 fixed to an axial projection 17 of the input section 5, and the leaf spring member 18 supports a fly weight 19. The friction lining 20 is fixed. In the illustrated directly connected position of the vibration damper 8, the vibration damper 8 is lifted by a centrifugal force acting at a predetermined rotation speed from a protrusion 21 that protrudes from the input portion 5 of the vibration damper 8 in the axial direction. It abuts against the drum-shaped axial projection 22 of the portion 9, thereby locking or directly connecting the vibration damper 8 after a predetermined number of revolutions. The leaf spring member is elastically formed in the radial direction, and separates the fly weight from the protruding portion 22 and abuts on the protruding portion 21 when the number of rotations decreases from a predetermined number of rotations.
