摘要： The invention concerns a kinetic energy recovery system for use in a vehicle driveline. The system has a flywheel (24) serving to store energy. A continuously variable transmission (32) serves to transfer drive between the flywheel and a driveline of the vehicle at a steplessly variable CVT speed ratio. The continuously variable transmission has a variator (34) which has a rotary variator input (40) and a rotary variator output (42). The variator serves to transfer drive between its input and output at a continuously variable variator speed ratio. The continuously variable transmission further comprises a shunt gear arrangement (36) having a first rotary shunt input which is drivably coupled to the rotary variator input, a second rotary shunt input which is drivably coupled to the rotary variator output, and a shunt rotary output which is drivably coupled to the flywheel.

摘要： A transmission arrangement is disclosed which comprises first and second variators (166, 169) each of which comprises an input race (150, 154) and an output race (152, 156). A plurality of rollers (276, 278) is arranged to run upon the input and output races to transfer drive from one to the other. The races are mounted for rotation about a common axis and the inclination of the first variator's rollers is variable independently of the inclination of the second variator's rollers, so that the two rollers are able to provide independently and continuously variable drive ratios. To provide traction between the rollers and races, a biasing device (216, 217) applies an axial force to one of the races, urging the rollers and races into engagement with each other. Each variator is provided with a shunt gear for providing forward, reverse and g eared neutral ratios, and to couple the variator input to the shunt gear a coupling member (160) passes through the outer variator races.

摘要： A continuously variable ratio transmission unit having a housing (116) and input (102, 106) and output (100) discs paired to define first and second toroidal cavities. The discs (100, 102, 106) are mounted to the housing for rotation about a common axis. First (110) and second (112) rollers—or more typically first and second sets of rollers—are respectively arranged in the first and second cavities and serve to transmit drive between the input and output discs. First (130) and second (148, 150, 152) actuators act on the respective rollers. The first actuator is coupled to a first carrier part (126) which can be mated with the housing introducing it to the housing along a direction generally parallel to the variator axis. The second actuator is coupled to a second carrier part (146) which can be mated with the housing by introducing the second carrier part to the housing along a direction non-parallel to the variator axis.

摘要： A multi-regime continuously variable ratio transmission system has coaxial system input and output shafts (16, 24), a continously variable ratio transmission unit (V) connected coaxially to the system input shaft (16) and having a coaxial variator output shaft (18) and a mixing epicyclic gear train (E1) having an input sun gear (S1) drivably connected to the variator ouput shaft (18), a planet carrier (C1) drivably connected to the system input shaft (16) and a planet gear (P1) mounted on the planet carrier ((C1). The planet gear (P1) drives a first intermediate output shaft (22) arranged coaxially with the system input shaft (16) and selectively connectable to the system output shaft via a first clutch (H) in high-regime operation of the transmission. The planet gear (P1) also provides the input for a second epicyclic gear train (E2) having an output (C2) which is selectively connectable to the system output shaft via a braking element (L) for low-regime operation of the transmission. The arrangement minimises the number of gear meshes, thereby minimising transmission losses and the absence of an annulus in the mixing epicyclic gear train (E1) allows more freedom in the choice of gear sizes, thereby permitting reduced gear speeds.
