摘要： A hybrid vehicle drive system for a vehicle includes a first prime mover, a first prime mover driven transmission, and a rechargeable power source. The hybrid vehicle drive system further includes an interface between the transmission and the prime mover for coupling to an electric motor. The electric motor can be in direct or indirect mechanical communication with a hydraulic pump. The electric motor can receive power from the prime mover driven transmission through the interface.

摘要： An example includes a hydraulically controllable coupling to couple a rotating input and to an output to rotate, or to decouple the input and the output, with coupling and decoupling modes selected by switching a hydraulic device such as a vane pump between a pumping mode and a mode in which it does not pump. In an example, the system cooperates with a transmission to increase the number of possible gear ratios in some examples.

摘要： A hydraulic driveline for a vehicle may have a main hydraulic circuit with a first hydraulic displacement unit and a second hydraulic displacement unit. The driveline may have a hydraulic accumulator assembly which is selectively fluidly connected to the main hydraulic circuit by one or more controllable valves of a first group of valves. The driveline may also have a first secondary module that has a first fluid communication of the hydraulic accumulator assembly with a first secondary hydraulic load of the hydraulic driveline. The first fluid communication may be one or more controllable valves that allow connecting the hydraulic accumulator assembly with the first secondary load or separating the hydraulic accumulator assembly from the first secondary load and that belong to a second group of valves. The controllable valves of the second group of valves are controllable independently of the controllable valves of the first group of valves.

摘要： A hydraulic hybrid system for rotatory applications has an actuator (49, 91) in the form of a motor pump unit (91). The motor pump unit is coupled to a rotatory-operating device (94) and works as a consumer of hydraulic energy in one operating state of the device (94) and works as a producer of hydraulic energy in another operating state of the device (94). A hydraulic accumulator (1) can be charged by the motor pump unit (91) for energy storage in the one operating state and can be discharged for energy release to the motor pump unit (91) in the other operating state. The hydraulic accumulator is an adjustable hydropneumatic piston accumulator (1) in which a plurality of pressure chambers (19, 21, 23, 25) are delimited by active surfaces (11, 13, 15, 17) of different sizes on the fluid side of the accumulator piston (5). An adjusting arrangement (51) connects a selected pressure chamber (19, 21, 13, 25) or a plurality of selected pressure chambers (19, 21, 23, 25) of the piston accumulator (1) to the actuator (49, 91) depending on the prevailing pressure level on the gas side of the piston accumulator (1) and at the actuator (49, 91).

摘要： An engine stop-start fuel saving system for a vocational vehicle propelled by a conventional internal combustion engine and powertrain. The system uses a low storage capacity, rapid recharge, high cycle life electric energy storage device, such as an ultracapacitor. The system also includes a generator that is coupled to the engine and that is connected to recharge the electric energy storage device, as well as a motor that is powered by the energy storage device and that is coupled to the engine. The system also includes a controller that can activate the motor to restart the engine when it is stopped, and engage the generator to recharge the electric energy storage device, and that can subsequently stop the engine again when the electric energy storage device has reached a threshold charge level. The electric energy storage device also powers at least one of: integral vehicle equipment; peripheral vehicle equipment; or an electrical outlet circuit with a socket for external plugin equipment.

摘要： A transmission system selectively coupled to an engine crankshaft of an internal combustion engine arranged on a vehicle includes a waste heat recovery (WHR) system, a brake assembly and a phase-change thermal heat storage system. The WHR system selectively circulates a WHR fluid in the transmission system. The brake assembly selectively couples a transmission output shaft to a drive axle. The brake assembly is configured to operate in a braking mode that retards relative rotation between the transmission output shaft and the drive axle while generating heat. The heat storage system includes a housing defining at least one cavity and a fluid transfer manifold. A phase-change material is disposed in the cavity that is configured to change phase during the braking mode. The WHR system circulates the WHR fluid through the fluid transfer manifold collecting braking heat to be used at a later time in the form of driveline power.

摘要： An electro-hydraulic hybrid system for a vehicle utilizes both the advantages of the hydraulic hybrid system and the electric hybrid system to maximize the collection of energy lost during a braking process and to provide launch assists in an acceleration process. The electro-hydraulic hybrid system includes an ECU that controls the electro-hydraulic hybrid system, a hydraulic drive pump, an accumulator, a hydraulic reservoir, a hydraulic pump, an electric motor, a power converter, and a battery. The hydraulic reservoir is in fluid communication with the accumulator through the hydraulic drive pump that functions as the main component of the hydraulic regenerative braking system. The hydraulic reservoir is also in fluid communication with the accumulator through the hydraulic pump that acts as the main component of the electro-hydraulic inter-conversion unit along with the electric motor, the at least one battery, and power converter that are electrically connected to each other.

摘要： The present invention introduces a retrofit method of regenerative braking where no components of an automobile are to be replaced or removed and none of their functionality is modified. The recovering energy system is implemented as an additional, one piece, complete device, placed onto the existing automobile wheel's hub, and covered by the automobile's wheel. The system includes a housing, turbines, accumulators, and valves which act to both store and dispel energy as needed. This method of regenerative braking is therefore applicable to all the automobiles, independent or their power source, to newly built automobiles and those already on the road.
