Problems solved by technology

Therefore, three relatively rotatable shafts, namely the drive shaft, stator shaft, and turbine shaft, are arranged inside the output gear, and two high-performance bearings that can withstand the load of the output gear need to be arranged between the double mating parts of these shafts , which makes the structure of the bearing complex

Embodiment Construction

[0060] exist figure 1 In and 2, the crankshaft 2 is supported by the crankcase 1 of the engine E mounted on the motorcycle through the main bearing 3 . The output gear 4 , the torque converter T, the lock-up clutch C2 and the starting clutch C1 are mounted on the portion of the crankshaft 2 protruding to the outside of the main bearing 3 from the side of the main bearing 3 toward the outside of the crankcase 1 in this order.

[0061] First, refer to image 3 To describe the structure of the starting clutch C1.

[0062] The starting clutch C1 includes: a first drive plate 5 connected to the end of the crankshaft 2; a pair of first clutch shoes 7 and 7 connected by a pivot 6 Swingably supported on the first drive plate 5; a pair of first return springs 8 and 8, the pair of first return springs 8 and 8 are connected between the first clutch shoes 7 and 7, and push the first clutch shoes 7 and 7 ; and a closed-end cylindrical output drum 9 arranged to surround the first clutch ...

Abstract

A power transmission device for a vehicle includes an output gear, a torque converter, and a starting clutch, which are arranged in this order on a crankshaft from a crankcase side outward. The turbine rotor is arranged between the output drum of the launch clutch and the pump impeller. The pump impeller and output drum are connected by connecting parts. The turbine shaft connecting the turbine rotor hub and the output gear is rotatably fitted on the outer circumference of the crankshaft through a bearing. A hollow stator shaft connected to the stator hub is relatively rotatably sleeved on the outer periphery of the turbine shaft. Therefore, in the power transmission device for a vehicle, the hollow turbine shaft is directly supported by the drive shaft of the engine, thereby simplifying the bearing structure.

Description

technical field [0001] The present invention relates to a power transmission for a vehicle such as a motorcycle or an automobile, and more particularly to an improved power transmission for a vehicle in which an output gear, a torque converter and a starting clutch are in this order from The side of the engine body that supports the drive shaft is outwardly arranged on the drive shaft of the engine, the torque converter includes a pump impeller, a turbine rotor and a stator, and the starting clutch includes a clutch input part and a clutch output part, so that the drive shaft The power is sequentially transmitted to the starting clutch, torque converter and output gear. Background technique [0002] Such a power transmission device for a vehicle is known, for example, in the disclosure of Japanese Patent Application Laid-Open No. 2001-141025. [0003] In such a conventional power transmission device for vehicles, a hollow stator shaft connected to a stator is relatively rot...
