In addition, similar to the stripdrive CVT, the continuous change of the transmission ratio so that the driver can enjoy seamless smooth shifting, without any shift shock. Engine power transmitted to an input dial input dial to the rotational movement of the transmitting 機械專業(yè)中英文文獻翻譯 power to the wheel, and then passed through the rollers to the output of the turntable. By continuously changing the inclination angle of the power roller, CVT performs a smooth and continuous gear ratio changes. The size of the contact circle between the points of contact between the input wheel and the power roller circle size and the output of the dial and the power roller is changed according to the change of the inclination angle of the power roller. The size ratio of the circle corresponding to the input the turntable and output rotational speed ratio of the turntable, the rotational speed ratio is equal to the drive ratio. When the the output dial circle is larger, the rotation of the output dial slower than the input dial, which is equivalent to the traditional low end of the transmission. Conversely, output dial circle small, the rotation of the output dial faster than the input dial, which is equivalent to the highend of the traditional transmission. The momentum wheel is supported on the trunnion connected above and below the assembly and the hydraulic servo piston can move up and down. Power roller, this configuration allows each roller rotating around the trunnion. When the power roller axis through the wheel center, does not produce the force of the tilt of the wheel. Accordingly, since the wheel tilt remains unchanged, it is no change in the transmission ratio. Since the highspeed rotation of the turntable, as long as the wheel moves up or down. to , can be tilted. This immediate response to a gear ratio change instruction, the EXTROID CVT cause particularly rapid transmission ratio change. The inclination angle of the power roller hydraulic mechanism for manipulation. Despite the transmission ratio is changed by tilting the power roller, but not directly to the wheel afterburner. Instead, the force generated using the turntable so that the inclined roller when the vertical movement of the wheel from the center axis, the turntable on the roller tilt. As the highspeed rotary dial, dial the forces generated by the wheel movement and force the hours immediately tilt, so we can quickly feel the transmission ratio changes significantly. When the driver39。機械專業(yè)中英文文獻翻譯 英文原文 Stepless speed technology Stepless speed technology USES belt and the work of the Lord diameters driven pulley, cooperated with the power to deliver, can realize the TRANSMISSION ratio of the continuous change, and get the TRANSMISSION and engine condition the best match between. Common stepless transmission have hydraulic mechanical stepless transmission and belt type stepless transmission , the current domestic market of the vehicles already more and more. Editor this section stepless transmission and the origin of the automatic transmission Automatic transmission is easy to operate, reduce fatigue driving, born of the gear drive system, the control method, it can be divided into the hydraulic controlled hydraulic and electric automatic transmission hydraulic automatic transmission。s accelerator input, and the linear acceleration and deceleration.機械專業(yè)中英文文獻翻譯 機械專業(yè)中英文文獻翻譯 中文譯文 無級變速器 無級變速技術，它采用傳動帶和工作直徑可變的主、從動輪相配合來傳遞動力，可以實現傳動比的連
