Abstract

DC60 (17/02/48) Transmission system for small vehicles in which the crankshaft and input shaft of the transmission are Connected together through a fluid transmission device such as torque converter The primary reducer, fluid transmission device and gearshift clutch are arranged on the crankshaft respectively from On one side of the crankcase, which supports the crankshaft with its bearing inserted in between, to the outside, and the axial movement of the inlet parts, the pump impeller and turbine impeller on the crankshaft will cheap It is stopped by bearings and threaded nuts at the end of the crankshaft. Thus, the creep phenomenon of the fluid transmission device can be eliminated by controlling the gearshift clutch, and operating. Changing gears of the transmission can be carried out easily. In addition, the transmission system is simple structure and can improve the integration capability. Transmissions for small vehicles in which the crankshaft and input shaft of the transmission are Connected together through a fluid transmission device such as torque converter The primary reducer, fluid transmission device and gearshift clutch are arranged on the crankshaft respectively from On one side of the crankcase, which supports the crankshaft with its bearing inserted in between, to the outside, and the axial movement of the inlet parts, the pump impeller and turbine impeller on the crankshaft will cheap It is stopped by bearings and nuts that fit neatly at the end of the crankshaft. Therefore, the phenomenon The creep of the fluid transmission device can be eliminated by controlling the gearshift clutch, and operating. Changing gears of the transmission can be carried out easily. In addition, the transmission system is simple structure and can improve the ability to assemble better

Claims (5)

1. A powertrain for light vehicles in which the engine crankshaft and the multistage input shaft assembled parallel to the said crankshaft, are connected together. Through a fluid power transmission path, including a pump impeller connected to the engine, and a turbine impeller that It is connected to a multi-stage transmission, where the first reducer, the fluid transmission path and the gearshift clutch are assembled on Such engine crankshafts are respectively in the order indicated from one of the side walls of the crankcase. The crank, which supports the said crankshaft with bearings assembled between it, to the outside, such a gear shift clutch with an inlet part connected to the said crankshaft and output part. Connected To the impeller of the pump, the impeller is connected to the drive gear of the reducer. As mentioned above, the gears of the said primary reducer are connected to the said inlet shaft of the powertrain, where the axial motion of the parts enters, the pump impeller and the impeller. Burbine Such on such a crankshaft will be stopped by the said bearing. And the screw that is worn with The end of the crankshaft. 2. Transmission for light vehicles according to claim No. 1, where the crankshaft This includes a large diameter shaft section positioned close to the bearing, and a small diameter shaft section connected to the end of the large diameter shaft section. It passes through And where the input part is clamped and fixed on a diameter shaft. Such a small size By the above stage And such nuts that are threaded at the end of the shaft section Such a small diameter And the axial movement of the pump impeller and the said turbine impeller will be interrupted by the said bearings and the input parts. 3.Transmission for light vehicles in which the engine crankshaft and the shaft Of the multistage transmission units are connected together through a fluid power transmission path, which includes the pump impeller at Connected to the said crankshaft. And the turbine impeller connected to the inlet shaft where the gear shifting clutch is inserted between the crankshaft and into it. The series is related to the transmission path of the fluid. The way of transmission of the said fluid and clutch The gear shift will be assembled like a common axis. So that the portion of the outer surface of the pump impeller The shape of the fluid transmission path is inherited in the niche, which is present on one side of the clutch. Change such gear 4.Transmission for light vehicles according to claim 3, where the niche is open, is in the lower cylinder-shaped clutch housing of the said shift clutch. 5. Transmission for small vehicles according to claim No. 4, where the pump impeller The clutch and the gearshift clutch are connected together within the opening.
