An energy harvesting system (100) for harvesting energy from vehicles travelling on a road (102). The system (100) includes a plurality of flexible hoses (104) which are embedded in a road overlay (106). Each hose (104) holds a hydraulic fluid, e.g. water, such that, when a vehicle wheel (108) passes over the hose (104), the fluid is displaced. The system (100) further comprises a plurality of double-acting hydraulic fluid cylinders (109) which are in fluid flow communication with the fluid in the hoses (104) and are configured to convert pressure applied to the fluid into rotary motion which drives an electrical generator. One hose is connected to each end of the cylinder (109) to drive it in opposite directions to induce linear reciprocating motion which is converted to rotary motion by way of a mechanical drivetrain. Due to the double action, it drives at least two drive shafts simultaneously.

The invention provides a stepless automatic transmission and a vehicle, and relates to the technical field of vehicle power transmission systems. The stepless automatic transmission comprises a belt wheel transmission mechanism connected with an output shaft of an engine, and further comprises a planet gear mechanism, a differential, a transmission gear set and a clutch set, wherein the differential is connected with the planet gear mechanism, and comprises a transmission output shaft; the transmission gear set is in transmission connection with the output shaft of the engine and the planet gear mechanism; and the clutch set is connected with the planet gear mechanism and the transmission gear set, and comprises a first clutch and a second clutch. The stepless automatic transmission is provided with the planet gear mechanism connected with the differential and the clutch set connected with the planet gear mechanism and the transmission gear set; through change of working states of theclutches in the clutch set, the speed ratio range of the stepless automatic transmission is widened; the structure is simple; and the dynamic property and the economy of the vehicle are improved.

The invention relates to a multi-disc clutch (1) for a hybrid module (2) of a motor vehicle drivetrain (3), having a first clutch component (4a) and a second clutch component (4b) which can be coupled as desired to the first clutch component (4a) for conjoint rotation, wherein the first clutch component (4a) has a first carrier (7) which is provided for connection to a rotor (5) of an electric machine (6) for conjoint rotation and has a first group (8) of frictional elements (9a, 9b, 9c) which is connected to the first carrier (7) for conjoint rotation, and the second clutch component (4b) has a second carrier (10) and a second group (11) of frictional elements (12a, 12b) which is coupled to the second carrier (10) for conjoint rotation, wherein the frictional elements (9a, 9b, 9c) of the first group (8) are arranged in alternation with the frictional elements (12a, 12b) of the second group (11) next to one another in an axial direction of a common rotational axis (13), wherein a first frictional element (9a) of the first group (8), which first frictional element is connected in an axially fixed manner to the first carrier (7), is connected to a second frictional element (9b) of the first group (8) for conjoint rotation via a driver element (14) which is held for conjoint rotation and in an axially relatively displaceable manner on the first frictional element (9a) of the first group (8). The invention also relates to a hybrid module (2) and a dual clutch device (30), each designed with a multi-disc clutch (1). The invention also relates to a drivetrain (3).
