Hydrodynamic torque converter which comprises blade wheels in the form of a reactor, a pump wheel and a turbine wheel with individual blades which are connected to an outer wall, whereby a torque can be transmitted from the pump wheel to the turbine wheel by means of pressure medium which flows along a flow path from the pump wheel to the turbine wheel, and is transported via the reactor back to the pump wheel, whereby at least one blade wheel comprises at least one stabilizer ring which creates a connection of the individual blades on their exposed sides, and by means of which stabilizer ring the flow path of the pressure medium can be influenced to reduce the flow losses.
摘要:
A hydrokinetic torque converter with a housing (23, 26) connected to an internal combustion engine; a turbine (21); and a bridge coupling or lock-up clutch (45) which has a plurality of friction linings (1, 7; 31, 39, 40; 54, 57) that can be brought in a predeterminable order and independent of one another into active connection with a particular associated friction surface for establishing a frictional connection between the housing (26) and the turbine wheel (21). Under pressure the converter bridge coupling acts initially as a single-surface and later as a double-surface converter coupling. In addition, the bridge coupling can have a low transmission capacity per pressure unit in the low pressure range and the transmission capacity can be increased disproportionately starting at a certain pressure range.

A lockout clutch on a torque converter includes an axially deflectable piston through which torque can be transmitted from the drive side of the torque converter to its output side. The lockout clutch also has a torsional vibration damper having an input part connected to the piston and an output part connected to the turbine wheel of the torque converter. One of the input part and the output part includes a cover element with control elements for energy storage devices acting on the torsional vibration damper on at least one radial support of the cover element. The control elements are designed to project into the cover element with a depth at which the associated energy storage devices rests on a control element along substantially the extension width in the contact area of the control element. The control elements are also designed to avoid penetration to the axial support at least at the point where the other of the input and output elements engages the energy storage elements. This engagement occurs with substantially axial projections, on which axial securing devices to retain the energy storage devices are provided. The axial projection are designed so that pressurization of the energy storage devices is ensured over their entire width in the axial extension direction of the axial projections.
摘要:
A hydrodynamic torque converter with a pump wheel, a turbine wheel, and a stator, which combine to form a hydrodynamic circuit, where the flow conditions in the hydrodynamic circuit can displace the turbine wheel axially toward the pump wheel when the converter is operating in pull mode and in the opposite direction when operating in push mode, where at least one axial bearing on the drive side of the freewheel and at least one drive-side thrust washer establish a working axial connection between the turbine wheel and a component of the freewheel. The drive-side thrust washer has a stationary element, by which the washer is in axial contact with a first freewheel component, and a pressure-exerting device, which is in working connection with this stationary element, is free to shift position in the axial direction relative to the stationary element, and, as a result of the action of a compensating element, remains in contact with both the drive-side axial bearing and a second freewheel component regardless of the axial position of the turbine wheel with respect to the pump wheel, whereas the stationary element arrives in axial contact with the drive-side axial bearing only after the turbine wheel has come to within a very short axial distance of the pump wheel.
摘要:
An idler wheel hub with freewheel mechanism, which encompasses an inner freewheel ring and an outer freewheel ring. Located radially between the freewheel rings are an inner cage and an outer cage. These cages are provided with recesses so that clamping bodies can penetrate therein. The clamping bodies are directionally prestressed so as to be in contact with the freewheel rings. The axial extension of the components is limited by side plates, which are located between the freewheel rings, and the freewheel rings are in turn centered by the side plates. One of the side plates forms a single part with the outer cage of the freewheel mechanism. The second side plate locks securely into the outer cage of the freewheel mechanism. The plates are provided with axially outwardly arranged glide devices. At least one of the side plates is attached in a turn-proof manner relative to the outer freewheel ring.
摘要:
A converter housing of a hydrodynamic torque converter with a driver, is formed with a converter cover which is rotatable about a center axis. The driver is arranged at a side of the cover facing a drive in an area preferably extending substantially radially. The driver is in an operative connection with a receptacle of a drive element which is associated with the drive and having a center axis aligned with that of the converter cover. The driver has a platform which is fastened to the converter cover at a predetermined radial distance to the center axis of the converter cover without consideration of the radial distance of the receptacle of the drive element from the center axis of the drive element. At a side of the driver remote from the converter cover, a driver member projects in the direction of the drive element. The radial position of the driver member at the platform is determined so that its radial distance to the center axis of the converter cover corresponds to the radial distance of the receptacle from the center axis of the drive element.

A torque converter according to the present invention includes a converter housing, a turbine wheel arranged in the converter housing so as to be rotatable relative thereto around a converter rotational axis (A), and a bridge coupling for the substantially rotation-proof selective connection of the turbine wheel to the converter housing. The bridge coupling has a coupling mechanism connected in substantially rotation-proof fashion to the turbine wheel and includes a friction surface which may be selectively brought to rest on a counter friction surface on the converter housing or selectively connected in rotation-proof fashion thereto. The friction surface is provided on a friction surface carrier connected in rotation-proof fashion to a coupling component that is rotatable with the turbine wheel. The coupling component is pivotable relative to the friction surface carrier around a circumferential line or a circumferential line region naming around the converter rotational axis (A).
