BMW hybrid power car plug -in all -in -one transmission belt two -way tension structure
For the same purpose, GM's BSG band transmission uses the multi -wedge tie tieter shown. The tights assembly consists of a supporting plate, a hydraulic shock absorber, a spring, and a tensor wheel. The support plate is installed on the cylinder as a shaft by supporting sales, and the other end is connected to the engine cylinder through a hydraulic shock absorber.
Fig
When the all -in -one machine is rotated as a starting motor -driven crankshaft, the upper side of the multi -wedge belt is tight side, the left tens of tension is moved up, and the spring force increases. At the same time, the tightrier bracket wraps around the support, and the right tight wheel moves left to eliminate the relaxation amount of the lower side of the wedge belt, and keep the contact pressure of the transmission belt and the wheel under the action of the spring. The use of hydraulic damping in the structure can well eliminate the vibration and noise in the operation when the power is replaced.
4. Coaxial mechanical coupler
(1) The layout of the same shaft mechanical coupling device.
The coaxial mechanical coupler refers to the two acts of the two effects on the same axis. At present, the dual -power torque coupling is mainly used in the structural form of the motor coaxial compassion. The torque coupling structure of the ISG motor between the crankshaft and the transmission.
For torque coupled parallel hybrid driving systems, its simple and compact structure is a coaxial structure. Among them, the motor rotor is coupled.The motor can be installed between the engine and the transmission device. It can also be placed between the transmission device and the last -class driver.
Hybrid car electromagnetic torque coupling features
① Shown in the coales and electrical coupling structure between the motor installed between the motor and the transmission. The rotor rotates with the crankshaft together and has the function of the generator. On the other hand, the rotor rotating the crankshaft after the motor is power -on, providing external power for the initial working cycle of the engine. In addition to the engine starting and power generation function, the motor also has the function of providing auxiliary power and braking energy recycling for vehicles. Because the ISG motor rotor has a certain quality, the motor rotor can replace the crankshaft flywheel function, so the engine flywheel is canceled in a mild hybrid power system. Due to the restrictions of the layout space, the ISG motor is best to use a flat structure.
② In the transmission structure shown , when the motor torque is directly transmitted to the last -class driver, the transmission device can only adjust the engine torque. system. However, it should be noted that when the vehicle stops and the motor rigid is connected to the drive wheel, the motor cannot charging the battery by the engine drive.
(2) The characteristics of the motor of the coaxial mechanical coupler.
① The motor is large in diameter and can output a large driving torque. It can directly drive the crankshaft rotation starting engine, which can cancel the external motivation, which can achieve low noise, fast, and stable stop/start.
② Using electric motor with a large power, its electric function can increase the torque and speed of the transmission system drive, and reduce the tail gas emissions during the engine at low speed when the car starts or low -speed uphill.
③ The role of motor rotor replaces the flywheel. It can switch between the motor and the generator through its own rotation inertia, balance the fluctuation of the internal combustion machine crankshaft, and becomes a active flywheel to play a role of shock absorber.
④ Install the ISG motor at the coaxial axis. The accessories of the internal combustion engine can be driven by electricity. This can save all the tooth belts and gear sets used for transmission. The arrangement of the internal combustion engine accessories can be more flexible.
⑤ ISG can provide 10KW power output when used as a generator, and the efficiency within the full speed range is more than 80%. Ordinary vehicle generators are usually driven by the label axis of the internal combustion engine through the belt. The maximum output power is only 1.5 to 2.5kW, the maximum efficiency of the generator is 70%, and only 30% at high speed. This cannot meet the power of modern automotive electronic products. Demand.
