Definitions
- the invention relates to a CVT drive train with a drive, a starting element, a continuously variable variator and a differential.
- the invention further relates to a method for operating such a CVT drive train.
- CVT is called a continuously variable transmission, wherein the letters CVT for
- Continuously variable transmission stand In order to increase the transmission range of a continuously variable transmission, ie its spread, it is known, for example, from the European patent application EP 2 275 709 A1, to subordinate the continuously variable transmission to a switchable planetary gear.
- the switchable planetary gear allows a two-range circuit and a reverse circuit.
- German published patent application DE 102 61 900 A1 it is known from German published patent application DE 102 61 900 A1 to provide a multi-range CVT with fixed shiftable gears, for example for starting or for maximum speed, but in the operation of these fixed ratios the variator is decoupled. Consequently, there is only one stepless area, not all driving areas can be steplessly steered.
- the object of the invention is to simplify the construction and / or operation of a CVT drive train with a drive, a starting element, a continuously variable variator and a differential.
- the object is achieved in a CVT drive train with a drive, a starting element, a continuously variable variator and a differential in that a variator bridging direct shift is connected directly to the drive.
- the direct switching stage Due to the direct connection of the direct switching stage to the drive, the direct switching stage can advantageously be used independently of the starting element.
- the direct shift stage may, for example, be connected to a gear used in conventional CVT drive trains to drive a hydraulic pump. Therefore, such a gear is also referred to as impeller. If the drive comprises an internal combustion engine or an internal combustion engine, then the direct shift stage bridging the variator is driven directly by the internal combustion engine or the internal combustion engine.
- the direct shift stage in the context of the present invention is preferably used exclusively when driving a motor vehicle equipped with the CVT drive train.
- a preferred embodiment of the CVT drive train is characterized in that the direct shift stage bridging the variator is connected to a crankshaft with the interposition of a torsional vibration damper.
- a torque of the drive in particular the internal combustion engine or the internal combustion engine, issued.
- the torsional vibration damper is advantageously used to decouple unwanted torsional vibrations, which occur during operation of the drive, in particular of the internal combustion engine or of the internal combustion engine, from the CVT drive train. This prevents unwanted damage in the CVT drivetrain caused by rotational irregularities.
- the direct shift stage comprises an intermediate gear stage which is in engagement with a spur gear of the differential.
- the intermediate gear stage comprises at least one gear which is non-rotatably connected to the drive, in particular an impeller, and is in engagement with the spur gear of the differential.
- the direct switching stage comprises as a switching device, for example, a dog clutch.
- the direct shift stage can optionally also be equipped with a synchronization device.
- a further preferred embodiment of the CVT drive train is characterized in that a partial transmission between the variator and the differential is arranged.
- the partial transmission is, for example, a reduction gear.
- the partial transmission is preferably arranged between a variator output and the differential.
- the direct shift stage is preferably arranged between the starting element and a variator input.
- a further preferred embodiment of the CVT drive train is characterized in that the partial transmission is designed as a solid-state transmission with a forward branch and a backward branch.
- the fixed-speed transmission further advantageously comprises an idling position in which the variator is decoupled from the output.
- the forward branch advantageously serves to facilitate forward drive operation of a motor vehicle equipped with the CVT powertrain.
- the reverse branch allows a reverse drive operation of the motor vehicle.
- the partial transmission is designed as a dual-range transmission, in particular as a planetary gear.
- the dual-range transmission allows, for example, a driving operation in a first region, which is also referred to as low region, and in a second region, which is also referred to as high region. In the first area, for example, can be driven with a larger translation than in the second area.
- the designed as a planetary gear dual-range transmission advantageously also allows the representation of a reverse gear.
- the starting element is designed as a torque converter or starting clutch. It is important that the drive, regardless of the design of the starting element, directly to the direct-shift stage bridging the variator can be connected. In the case of a starting clutch, this can be achieved in a simple manner, for example, by connecting the direct shift stage bridging the variator in a torque-proof manner to an input of the starting clutch.
- the starting element is designed as a torque converter
- the direct connection of the direct switching stage bridging the variator to the drive can take place, for example, via a converter housing.
- a separating clutch integrated in the torque converter enables the starting element to be disconnected from the variator.
- the decoupler integrated into the torque converter enables the variator to be switched off, so to speak. In the version with the starting clutch, the variator can be disconnected from the drive by the starting clutch or switched off.
- a further preferred embodiment of the CVT drive train is characterized in that the starting element, the variator, the partial transmission, the direct shift stage and the differential are arranged in front-transverse construction.
- the terms front and cross refer to the installation location of said components in a motor vehicle.
- Front means that the drive is arranged with the starting element, the variator, the partial transmission, the direct shift stage and the differential in a front region or front region of the motor vehicle.
- Cross means that the drive is installed transversely with the mentioned components.
- the direct shift stage is positioned below a crankshaft center.
- the direct switching stage is advantageously positioned in the direction of the differential.
- the above-mentioned object is alternatively or additionally achieved in that the direct shift stage fe is used for a low-consumption driving in a consumption-relevant operating point.
- the direct shift mare may for example be used in a transmission final transmission point.
- the direct shift stage can be used for a range change in a specific gear ratio. This means that the direct shift stage is used for a range change with always the same gear ratio.
- the invention further relates to a starting element, a variator, a partial transmission, a direct shift stage and a differential for a previously described CVT drive train.
- the invention also relates to a transmission with a continuously variable variator and a direct shift stage bridging the variator.
- the transmission may additionally comprise a previously described starting element and / or a previously described differential.
