    • A new and unique saddle-riding type motorcar having four wheels comprising two front wheels and two rear wheels, wherein each of the front and rear wheels has a balloon tire mounted thereon and only the front wheels are rotatably supported on axles in such a manner as to turn in both directions relative to the longitudinal axis of the motorcar and the latter is steered by steering the front wheels by means of a bar handle constituting a steering mechanism. The motorcar includes a frame structure comprising a pair of upper frames, a pair of lower frames and a plurality of spacer frames, said pair of upper frames comprising a pair of fore-end portions extending downward from a bent portion at a forward inclination angle and a pair of inclined portions extending rearward by a certain distance from said bent portion at a gentle downward slope, said pair of lower frames being fixedly connected to the pair of upper frames by way of a fore axle at their fore end and by way of vertically extending frames at their rear end and said spacer frames extending in the transverse direction relative to the upper and lower frames so as to connect one of the upper frames to the other and one of the lower frames to the other. A steering head is located at the bent portion of the upper frames. Supporting sections are disposed at both the end-parts of the fore axle and at the rearmost end-parts of the lower frames to support the wheels. A suspension mechanism may be disposed at least on one of the front wheels and the rear wheels and each of the rear wheels may include an independent driving axle adapted to be swingably supported by means of an independent swing arm and an independent suspension mechanism.
    • 一种独特的鞍式摩托车,具有四个车轮,包括两个前轮和两个后轮,其中前轮和后轮中的每一个都安装有气球轮胎,只有前轮可转动地支撑在车轴上, 相对于汽车的纵向轴线在两个方向上转动,并且后者通过构成转向机构的杆把手转向前轮来转向。 该汽车包括一框架结构,该框架结构包括一对上框架,一对下框架和多个间隔框架,所述一对上框架包括从弯曲部分向前倾斜的角度向下延伸的一对前端部分, 一对倾斜部分,以一个平缓的向下倾斜向后延伸一定距离的所述弯曲部分,所述一对下部框架通过前轴在其前端和垂直方向上固定地连接到所述一对上部框架 在其后端延伸框架,并且所述间隔框架相对于上框架和下框架在横向方向上延伸,以便将上框架中的一个与另一框架和下框架中的一个连接。 转向头位于上框架的弯曲部分。 支撑部分设置在前轴的两端部和下框架的最后端部,以支撑车轮。 悬挂机构可以设置在前轮和后轮中的至少一个上,并且每个后轮可以包括独立的驱动轴,其适于通过独立的摆臂和独立的悬挂机构可摆动地支撑。

    • A drive force transmission apparatus includes a housing connected to one of two shafts that are rotatable relative to each other, a rotary shaft rotatably supported by the housing and connected to the other shaft, and a multiple disc clutch composed of a plurality of outer plates engaged with the housing in the rotational direction and a plurality of inner plates engaged with the rotary shaft in the rotational direction. The multiple disc clutch transmits rotational torque between the housing and the rotary shaft through frictional engagement between the outer plates and the inner plates. The apparatus also includes a pressure generation mechanism for generating a pressure corresponding to a rotational-speed difference between the housing and the rotary shaft and for applying the generated force to the multiple disc clutch via a piston. The pressure generating means is composed of a plurality of rotary blades accommodated within a cylindrical space formed between the piston and the housing and rotating together with the rotary shaft, a viscous fluid charged into a plurality of pressure chambers defined by the housing, the piston, and the rotary blades, and a free blade accommodated within at least one pressure chamber. The free blade is freely movable in the circumferential direction between the rotary blades.
    • 驱动力传递装置包括连接到可相对于彼此旋转的两个轴之一的壳体,由壳体可旋转地支撑并连接到另一轴的旋转轴,以及由多个外板接合的多片离合器 其中壳体沿旋转方向,并且多个内板在旋转方向上与旋转轴接合。 多片离合器通过外板和内板之间的摩擦接合在壳体和旋转轴之间传递旋转扭矩。 该装置还包括用于产生对应于壳体和旋转轴之间的转速差的压力并用于经由活塞将生成的力施加到多片离合器的压力产生机构。 压力发生装置由容纳在形成于活塞和壳体之间的圆柱形空间中并与旋转轴一起旋转的多个旋转叶片组成,被填充到由壳体,活塞等限定的多个压力室中的粘性流体, 和旋转叶片,以及容纳在至少一个压力室内的自由叶片。 自由叶片可在旋转叶片之间沿圆周方向自由移动。
