Definitions

• hybrid vehicle which is a combination of an internal combustion engine and an electric motor to protect the environment and to improve the fuel consumption.
• the electric machine can be operated as a generator and / or as an electric motor.
• the object of the invention is to provide a simple, cost-effective and space-neutral pump drive, which is particularly suitable for use in front-transverse arrangement or space-critical arrangements.
• the pump drive should also be usable when using a continuously variable belt pulley transmission (CVT).
• CVT continuously variable belt pulley transmission
• the conical-pulley transmission with electric machine can be operated in the following operating modes:
• a conical pulley 1 is shown in fragmentary longitudinal section.
• the conical-pulley transmission 1 comprises two conical pulley sets which are connected to each other by a belting means, such as a chain, for transmitting torque.
• a belting means such as a chain
• Such belt pulley belt transmissions are also referred to as CVT transmission (Continuously Variable Transmission).
• Each conical disk set comprises an axially fixed conical disk and an axially displaceable bevel disk, which is also referred to as a windscreen.
• the inner disk carrier 28 is designed as a sheet metal part 30 which is integrally connected to the hollow cylindrical portion 29. From the hollow cylindrical portion 29 extends the Sheet metal part 30 with bevels and curves radially inwards. According to one aspect of the invention, the sheet metal part 30 simultaneously constitutes the input part of the torque sensor 8 and is provided for this purpose with ramp elements or spreading elements, which cooperate with the interposition of balls 31 with further ramp elements and spreading elements, which are provided on a sensor plate 32 of the torque sensor 8 ,
• the sheet metal part 30 is according to a further aspect of the invention, not only input part of the torque sensor 8 but also at the same time an input element of the first Kegei- disc set. The sheet metal part 30 is therefore an integral component.
• a multi-piece connecting part 37 is further connected at one end, the other end is in operative connection with a bearing plate 38.
• the bearing plate 38 is connected on the one hand with a rotor 3 of an electric rnaschine 2 to allow the transmission of torque between the electric machine 2 and the input member 30 of the first cone pulley set and vice versa, and on the other hand, the bearing of the rotor 3 by means of a bearing 35 in a Transmission housing 39 safe.
• Another bearing 36 is provided for supporting the shaft 12 in the transmission housing 39.
• the electric machine 2 comprises, in addition to the rotor 3, a stator 4 fixedly arranged on the transmission housing 39.
• a torque is introduced into the sheet metal part 30 via the starting clutch 5.
• the introduced torque is introduced via the torque sensor 8 in the transmission shaft 11.
• the sheet metal part 30 interacts with the feeler plate 32 of the torque sensor 8 via the balls 31 such that torque impacts cause an axial displacement of a feeler piston 33, whereby the contact pressure on the associated travel plate is increased.
• a pressure acting in a pressing cylinder pressure can be adjusted in proportion to the applied torque.
• a vehicle In the closed state of the starting clutch 5, a vehicle can be operated purely with the introduced via the shaft 12 torque, while the rotor 3 of the electric machine 2 rotates without load, the electric machine 2 itself is thus idle.
• the electric machine 2 could also be operated as a generator to allow the charging of an electrical energy storage or the operation of electrical loads.
• the electric machine 2 can be operated as an electric motor and support or boost the torque supplied via the shaft 12. If a shift transmission (eg for forward and reverse travel) with idling is provided behind the bevel belt transmission 1, in the idle position at standstill of a vehicle operated by means of the belt-driven conical-pulley transmission, generator operation with take a battery. Conversely, it is possible to start an internal combustion engine connected to the shaft 12 in the neutral position when the electric machine 2 is operating as a motor.
• a shift transmission eg for forward and reverse travel
• the operating field is provided by a pump, in particular a hydraulic pump, which is driven by a coupling element, not shown.
• the actuating piston 40 is biased by a preferably designed as a plate spring spring 52 in the axial direction against the outer disk carrier 16.
• the spring 52 is supported on the sheet metal part 30, which constitutes the inner disk carrier 28.
• the sheet metal part 30 is radially inwardly supported in the axial direction on a thrust bearing 54, which in turn is supported on a stop ring 55 which is partially disposed in an annular groove of the transmission shaft 11.
• a thrust bearing 54 By the axial bearing 54 is an axial movement of the sheet metal part 30 in Figure 1 to the left, that is to the driven shaft 12, prevented.
