Description

  • The invention relates to a conical-pulley transmission according to the preamble of patent claim 1.
  • From the German patent application DE 198 57 708 A1 is a conical-pulley with a starting clutch known which is designed as a hydrodynamic torque converter and connected via two spur gears to a transmission shaft of the first set of conical disc. From the German patent application DE 10 2005 027 614 A1 is a conical-pulley with a torque sensor and designed as a multi-plate clutch starting clutch is known which comprises a clutch basket with a cylinder portion are mounted in the outer disk of the starting clutch. A sensing element of the torque sensor is, indirectly via an axial toothing, rotatably connected to the peripheral surface of the cylinder portion, but axially displaceably connected. Axial means in the direction or parallel to the axis of rotation of one of the disc sets.
  • In recent years, a so-called hybrid vehicle has been developed, which is a combination of an internal combustion engine and an electric machine to protect the environment and to improve fuel consumption. The electric machine can be operated as a generator and / or as an electric motor. Accordingly, a combination of this hybrid vehicle and a continuously variable V-belt transmission has been proposed.
  • From the German patent application DE 101 13 504 A1 For example, a control apparatus for a conical-pulley transmission in which an output shaft of an internal combustion engine is connected to one end of a rotor of an electric motor via an electromagnetic clutch is known. A conical-pulley transmission consisting of two variable sets of conical disks (a primary conical disk set and a secondary conical disk set) and a V-belt or a chain is provided between the other end of the rotor of the electric motor and an output shaft.
  • The object of the invention is to provide a conical-pulley transmission for a hybrid vehicle according to the preamble of claim 1, which is simple in construction and inexpensive to produce. In particular, the conical-pulley transmission according to the invention should require less installation space in the axial direction than conventional conical-pulley belt transmissions.
  • The object is in a conical-pulley with a first and a second set of conical disks, each associated with a shaft and drivingly connected by a belt means are interconnected so that the translation is infinitely adjustable, with a first conical disk set associated input element, with a starting clutch with an input part and an output part and having an electric machine with a stator and a rotor, achieved in that the starting clutch and the electric machine are connected directly to the input member. The input member may be a portion of the input shaft of the conical pulley, a hub, or another component connected to the input shaft. The starting clutch is preferably designed as a wet-running multi-plate clutch and can be pre-assembled as a particularly space-saving component. The starting clutch and the electric machine can be arranged in the same axial portion of the transmission. The electric machine may be provided radially inside or radially outside of the starting clutch. This provides the advantage that no additional axial space is needed
  • An exemplary embodiment of the belt-driven conical-pulley transmission is characterized in that a torque sensor is assigned to the first set of conical disks and that the input element is an input part of the torque sensor. The first conical disk set is thus preceded by a torque sensor with a component which serves as an input element.
  • A preferred embodiment of the cone pulley belt transmission is characterized in that an output part of the starting clutch and an input part of the torque sensor are combined in a single sheet metal part. The sheet metal part has the function of a ramp plate or sensor plate of the torque sensor on the one hand. In addition, the sheet metal part exercises, for example, the function of an inner disk carrier of the run as a wet-running multi-plate clutch starting clutch.
  • Another preferred embodiment of the cone pulley belt transmission is characterized in that the rotor of the electric machine is connected to the input part of the torque sensor.
  • According to a preferred embodiment of the conical-pulley belt drive, the stator of the electric machine is connected to a housing of the belt pulley belt drive.
  • A further preferred embodiment of the cone pulley belt transmission is characterized in that the starting clutch and the electric machine are arranged radially outside of the torque sensor. This provides the advantage that no additional axial space is required for the starting clutch or the additional axial space for the electric machine is very low. Starting clutch, electric machine and torque sensors are thus arranged nested.
  • A further preferred embodiment of the cone pulley belt transmission is characterized in that the starting clutch is arranged in the same axial section as the torque sensor. The electric machine can also be arranged in the same axial section, namely radially inside or radially outside of the starting clutch. This provides the advantage that no additional axial space is needed.
  • According to a further embodiment of the conical-pulley belt transmission, the electric machine is arranged in the wet space of the conical-pulley belt transmission.
  • A further preferred embodiment of the cone pulley belt transmission is characterized in that the starting clutch is designed as a multi-plate clutch with an inner disk carrier which constitutes a ramp plate or sensor plate of the torque sensor. This provides in addition to the space savings the advantage that at least one part, in particular sheet metal part is saved.
  • A particularly preferred embodiment of the conical-pulley belt drive is characterized in that a direction of rotation reversing device is connected downstream of the conical-pulley belt transmission with a forward gear and a reverse gear, wherein the reversing device comprises a synchronizing device and a neutral position.
  • The electric machine is connected to the torque sensor behind the wet starting clutch directly into the power flow. In this case, the electric machine can be designed as a preassembled, space-saving component. In this way, the overall length of the transmission in the axial direction can be reduced. Thus, the cone pulley is particularly suitable for installation in front-transverse direction, since the electric machine requires little additional axial space. Furthermore, the starting clutch can advantageously be arranged nested with the torque sensor, wherein the electric machine engages directly in an input component of the torque sensor. The inclusion of the rotor can be realized by means of a sheet metal part design, which additionally allows the passing of the moment of the electric machine. Another advantage is that easy pre-assembly of the sub-assembly of the electric machine in the transmission housing is possible. This arrangement not only builds particularly short, but has a lower weight compared to the transmissions of the prior art. The known transmissions often require an additional clutch for disconnecting the electric machine from the internal combustion engine. When using a torque sensor whose known advantages such as relatively accurate specification of the required for safe operation contact pressure without increased Überanpressung the conical disks continue to be used and also in purely electrical operation.
  • By opening the upstream starting clutch is a purely electric driving possible. In addition, by opening the clutch during braking and a braking torque can be generated purely electrically. Therefore, there is no loss due to the thrust torque of the internal combustion engine. In this way, a particularly effective recuperation in overrun mode is possible when the electric machine acts as a generator. When the synchronous belt transmission a synchronized reversing gear for forward and reverse is followed by an idle, recuperation can be done only by the engine idling, for example, at a traffic light stop and relatively heavily drained battery.
  • The conical-pulley transmission with electric machine can be operated in the following operating modes:
    When the clutch is closed, a vehicle can be operated purely with the internal combustion engine while the rotor of the electric machine rotates, but the electric machine itself is idling. When the electric machine is operated as a generator, it is possible to charge an electrical energy store or to operate electrical consumers. Furthermore, the electric machine can be operated as an electric motor and assist or boost the internal combustion engine during operation. If a manual transmission (eg for forward and reverse travel) with idling is provided behind the conical pulley belt drive, in idle position at standstill of the vehicle, a generator operation with charging of the battery can take place. Conversely, the starting of the internal combustion engine in the neutral position is possible when the electric machine operates as a motor.
  • When the clutch is open, a purely electric driving is possible, but it can also brake or thrust energy into electrical energy be converted, wherein the thrust torque of the internal combustion engine causes no losses. As a result, an effective Rekuperationsbetrieb is possible without a second disconnect clutch or a freewheel between the engine and the electric machine must be provided.
  • Further advantages, features and details of the invention will become apparent from the following description in which, with reference to the drawings, an embodiment is described in detail.
  • The single accompanying figure shows a section of a belt pulley according to the invention in longitudinal section.
  • In 1 is a belt pulley transmission 1 partially shown in longitudinal section. The conical-pulley transmission 1 comprises two sets of conical disc (not shown) which are interconnected by a belt means, such as a chain, for transmitting torque. Such pulley-belt transmissions are also referred to as CVT transmission (Continuously Variable Transmission). Each set of conical disks comprises an axially fixed conical disk and an axially displaceable conical disk, which is also referred to as a spacer disk.
  • The conical-pulley transmission 1 includes a starting clutch 5 and a torque sensor 8th , The torque sensor 8th is on a gear shaft 11 arranged corresponding to the first cone pulley set of the conical-pulley transmission 1 assigned. One end of the transmission shaft 11 is in a, at least partially, designed as a hollow shaft driven shaft 12 arranged.
  • Radially outward on the driven shaft 12 is an entrance part 14 the starting clutch 5 welded. The entrance part 14 is designed as a sheet metal part, extending from the driven shaft 12 extending in steps and bevels radially outward and into a hollow cylindrical section 18 passes. In the hollow cylindrical section 18 of the entrance part 14 are outer plates 21 hooked. Thus, the input part 14 the starting clutch 5 an outer disc carrier 16 with which the outer lamellae 21 rotatably, but in the axial direction limited displaceable, are connected.
  • At the hollow cylindrical section 18 of the outer disk carrier 16 is an axial stop 24 attached. The outer disks 21 act to represent a wet-running multi-plate clutch with inner disks 25 together, the rotationally fixed, but limited in the axial direction displaceable, with an inner disc carrier 28 are connected. The inner disc carrier 28 includes within the hollow cylindrical section 18 another hollow cylindrical section 29 in which the inner lamellae 25 are hung.
  • The inner disc carrier 28 is as a sheet metal part 30 executed, which is integral with the hollow cylindrical section 29 connected is. From the hollow cylindrical section 29 the sheet metal part extends 30 with bevels and curves radially inwards. According to one aspect of the invention, the sheet metal part 30 at the same time the input part of the torque sensor 8th is and is provided for this purpose with ramp elements or spreading elements, with the interposition of balls 31 interact with other ramp elements and spreading elements, which on a feeler plate 32 of the torque sensor 8th are provided. The sheet metal part 30 According to another aspect of the invention, not only is the input part of the torque sensor 8th but at the same time also an input element of the first conical disk set. The sheet metal part 30 is therefore an integral component. With the Einganselement is still with its one end a multi-piece connecting part 37 connected, the other end with a bearing plate 38 is in active connection. The bearing plate 38 is on the one hand with a rotor 3 an electric machine 2 connected to the transmission of torque between the electric machine 2 and the input element 30 the first set of conical disc and vice versa, and on the other hand, the storage of the rotor 3 by means of a warehouse 35 in a gearbox 39 for sure. Another camp 36 is for storage of the shaft 12 in the gearbox 39 intended. The electric machine 2 includes next to the rotor 3 one fixed to the gearbox 39 arranged stator 4 ,
  • About the starting clutch 5 is in the closed state, that is when the inner plates 25 frictionally engaged with the outer plates 21 are connected, a torque in the sheet metal part 30 initiated. The torque introduced is via the torque sensor 8th in the gear shaft 11 initiated. The sheet metal part acts 30 over the balls 31 so with the feeler plate 32 of the torque sensor 8th together, that torque shocks an axial displacement of a feeler piston 33 effect, whereby the contact pressure is increased to the associated washer. With the help of the torque sensor 8th For example, a pressure acting in a pressure cylinder can be set proportional to the applied torque.
  • In the closed state of the starting clutch 5 A vehicle can be in with the over the shaft 12 introduced torque while the rotor 3 the electric machine 2 without load, the electric machine 2 itself is idle. The electric machine 2 but could also be operated as a generator to the store to allow an electrical energy storage or the operation of electrical loads. Furthermore, with the clutch closed 5 the electric machine 2 be operated as an electric motor and that over the shaft 12 support or boost supplied torque. If behind the conical-pulley transmission 1 a shift transmission (eg, for forward and reverse) is provided with idling, in the idle position at standstill of a vehicle operated by means of the conical-pulley transmission, a generator operation with charging a battery can take place. Conversely, starting is one with the shaft 12 connected internal combustion engine in the idle position possible when the electric machine 2 works as a motor.
  • With the clutch open 5 is a purely electric driving possible, but it can also be converted braking or thrust energy into electrical energy, the thrust torque of the engine no braking torque to the electric machine 2 generated, so no losses. As a result, an effective Rekuperationsbetrieb possible without a second clutch or a freewheel between the engine and the electric machine 2 must be provided.
  • The starting clutch 5 is via an actuating piston 40 operated, in the axial direction reciprocally movable on a torque sensor 8th facing end of the driven shaft 12 is guided. The actuating piston 40 extends in steps and curves substantially radially outward to the disk set of the starting clutch 5 , In a stepped area is the actuating piston 40 with the interposition of at least one seal 42 on the outer disk carrier 16 to an actuating pressure chamber 44 to limit.
  • In the operating pressure chamber 44 opens a fluid passage hole 45 which is essentially transverse to the driven shaft 12 extends. The fluid passage hole 45 connects the actuating pressure chamber 44 with an annular gap 48 moving in the radial direction between the gear shaft 11 and the driven shaft 12 is trained. In the annular gap or annulus 48 is a radial bearing 50 arranged, which is designed for example as a needle bearing. The annular gap 48 serves to an actuating fluid, in particular hydraulic medium, via the fluid passage hole 45 depending on demand in the operating pressure chamber 44 to lead.
  • The actuating fluid is provided by a pump, in particular a hydraulic pump, which is driven by a coupling element, not shown. The actuating piston 40 is by a preferably designed as a plate spring spring 52 in the axial direction against the outer disk carrier 16 biased. The feather 52 relies on the sheet metal part 30 off, the inner disc carrier 28 represents. When the pressure in the operating pressure chamber 44 the biasing force of the spring 52 overcomes, then moves the actuating piston 40 so against the disk set of the starting clutch 5 in that the inner lamellae 25 frictionally engaged with the outer plates 21 get connected. By this frictional engagement is the starting clutch 5 closed.
  • The sheet metal part 30 is radially inward in the axial direction on a thrust bearing 54 supported, which in turn on a stop ring 55 supported, partially in an annular groove of the transmission shaft 11 is arranged. Through the thrust bearing 54 becomes an axial movement of the sheet metal part 30 in 1 to the left, that is to the driven shaft 12 hin, prevented.
  • Of course, the conical-pulley transmission with electric machine can also be used without a torque sensor. In this case, the output part of the starting clutch and the connecting part or the bearing plate are connected directly to the input shaft of the transmission or an intermediate hub. A radial nesting, so arrangement in the same axial section of starting clutch and electric machine is possible and preferred.
