Definitions
- the invention relates to a power transmission unit with integrated breaker system for a motor vehicle according to the type of claim 1.
- the drive motor produces - eg. an internal combustion engine - one axle permanently driven. Accordingly, the engine is connected via a transmission with the drive axle.
- the coupling of a disconnect unit is designed as a form-locking coupling, by which the further drive axle is switched on or off.
- a synchronization may be provided, so that the positive coupling takes place only when the parts to be coupled have the same, approximately the same speed.
- the object of the present invention is to propose a power transmission unit in relation to the known solutions of improved design.
- the inventive solution consists in particular of an integration of the disconnect system in the power transmission of the Vorderachsabtriebs, wherein the input shaft of the power transmission device is coaxial with the front axle.
- the power transmission device has a spur gear that engages the teeth on a differential cage, the ' "Final Drive Gear”. This toothing on the differential gear is used for the output from the main gearbox to Vorderachsdifferential.
- the disconnect mechanism is designed as a form-locking coupling, in which a sliding sleeve form-fit - in the manner of a dog clutch - cooperates with another shaft part, can be pushed onto this.
- the sliding sleeve is engaged by a spring element in the direction of domes and moved by an actuator in the direction of uncoupling.
- the actuating device is a sector nut, an element which is engaged by an actuator into a shaft which is driven by the thread of the input shaft and which is driven directly by the engine, the transmission of the vehicle.
- the thread runs in the direction of the slope in such a way that the element engaged by the actuator is displaced by the sector nut in the direction of decoupling the sliding sleeve.
- the coupling is thus decoupled via the thread - against the spring force which presses the sliding or coupling sleeve in the coupling direction.
- the solution saves space and weight, since the thread and the sector nut are constructed separately from the dog clutch.
- the claw coupling is located directly between the spur gear and the drive train. Thus, the performance-leading path is very short.
- the power transmission device can be pre-assembled, adjusted and tested.
- the storage of the drive input shaft of the power transmission device takes place in an open structure, which can be inserted into the main housing of the transmission.
- FIG. 1 shows the drive system of a motor vehicle with permanent front-wheel drive and a switchable, acting on the rear wheels rear-wheel drive.
- An internal combustion engine VM acts on the wheels of a front axle VA via an automatic or manually shiftable transmission G as well as a front axle differential DVA.
- the front axle VA is thus permanently driven.
- the front axle differential DVA is coupled with a DCU disconnect unit, a transmission (power transmission PTU) with a clutch.
- the clutch integrated in the DCU disconnect unit is used to forward the drive torque to the rear axle HA.
- the disconnect unit DCU has an angle drive WG, which is connected to a drive shaft AW.
- the drive shaft AW drives the wheels of the rear axle HA in a manner known per se via a further angle drive and a rear-wheel coupling HK together with a downstream rear-axle differential DHA.
- the rear axle HK is designed as a multi-plate clutch and allows a continuously metered torque transmission.
- the drive torque transmitted to the rear axle HA can be set and, in particular, the drive shaft AW can be released when the clutch of the DCU disconnect unit is open. This then does not rotate with pure front wheel operation, which prevents power losses.
- the coupling in the disconnect unit, the rear axle coupling HK are activated by a controller, not shown, and communicate with it via Leitunbgen, a bus system.
- FIG. 2 shows the components of the disconnect unit DCU and the parts interacting with this unit in detail.
- the Vorderachsdifferential DVA has a spur gear SR! On, which cooperates with a spur SR2 of the DCC disconnect unit.
- the transmission G drives the front axle differential DVA via the spur gear SR1.
- the front axle differential DVA distributes the drive power to the propeller shafts of the front axle VR.
- the second spur gear SR2 can be coupled via a switchable clutch KDCU to the angular gear WG of the drive shaft AW.
- Angular gear WG together with the clutch KDCU and the spur gear SR2 are arranged in a housing GH DCU, which may be part of the transmission G.
- the spur gear R2 with the clutch KDCU are in turn arranged in a housing GH DCU, which is designed to be preassembled and the disconnect unit is mounted, tested and preset into the housing GH.
- a bevel gear KR of the Winch operation WG is rotatably supported by two tapered roller bearings in the housing GH DCU, the carrier of the DCU disconnect unit.
- the spur gear SR2 On the shank of the bevel gear KR designed as a hollow shaft sits mounted bar the spur gear SR2, which has a thread GWG to the left of the toothed area. Thread GWG and spur gear SR2 are made in one piece. Rotationally fixed on the shank of the bevel gear KR sits axially displaceable a sliding sleeve SM.
- the sliding sleeve SM On the side facing the spur gear SR2, the sliding sleeve SM has a coupling structure KT which interacts in a form-fitting manner with a corresponding structure of the spur gear SR2 (its flank).
- the axially movable sliding sleeve SM and the spur gear SR2 form the coupling KDCU the DCC disconnect unit.
- the sliding sleeve SM is pressed by a spring F in the axial direction against the spur gear SR2.
- the clutch KDCU is thereby closed, the bevel gear KR with the spur gear SR2 coupled ( Figure 3).
- An operating lever BH is pivotally connected to the upper end of a sliding fork SM comprehensive shift fork SG.
- the shift fork SG is mounted with its lower end pivotable about a mounted in the housing GH DCU bearing axis LA.
- the operating lever BH acts on the joint during a displacement in the axial direction (axis bevel gear KR) on the shift fork SG such on the sliding sleeve SM that thereby this can be moved on the shank of the bevel gear KR.
- the sliding sleeve SM is rotatable relative to the shift fork SG and is axially displaced during a pivoting movement of the shift fork SG.
- the free end of the operating lever BH - this extends in the axial direction of the shaft of the bevel gear KR - has a designed as a sector mother SMG fitting, which is formed corresponding to the thread GWG of the spur gear SR2 and by pivoting the operating lever BH into engagement with the thread GWG is brought.
- the actuating lever BH, the sector mother SMG is associated with an electrically actuated actuator AK acting on an electromagnetically moving plunger and a housing side pivotally mounted guide lever FH on the operating lever BH and so the sector mother SMG.
- the housing-side pivot bearing of the guide lever FH coincides almost with the joint of shift fork SG and lever BH together.
- the end of the guide lever FH is pivotally connected to the end of the linearly movable plunger of the actuator AK.
- Im coupled Condition - Figure 3 - is the sector nut SMG not engaged with the thread GWG - the sliding sleeve SM is in engagement with the spur SR2 - caused by the force of the spring F.
- the thread GWG runs in the direction of rotation of the spur gear SR2 (in the drive direction of the vehicle ) forward in such a way that the sector nut SMG engaging in the encircling thread GWG by actuation of the actuator AK shifts the sliding sleeve SM to the right in the direction of releasing the clutch KDCU - contrary to the force of the spring F.
- the sector nut SMG, the operating lever BH have been moved so far to the right - in the disengaging direction until the end of the guide lever FH - a molded at the bottom paragraph - engages in a locking shoulder RA of the sector mother SMG.
