    • A belt type continuously variable transmission including a primary pulley; a secondary pulley; a belt which is looped over the primary pulley and the secondary pulley; a reduction gear unit that transmits torque, which has been output from an internal combustion engine and then transmitted to a secondary shaft, to a final reduction gear unit that is provided so as to be coaxial with the secondary shaft of the secondary pulley; and a damper oil chamber which is provided between the secondary shaft and an input shaft of the reduction gear unit. A thrust force generated in the reduction gear unit due to an input of a driving force is transmitted to a hydraulic fluid in a damper oil chamber, and then absorbed. Therefore, a displacement of a relative position between the primary pulley and the secondary pulley is suppressed.
    • 一种带式无级变速器,包括主带轮; 次级滑轮; 环绕在主滑轮和次滑轮上的皮带; 将从内燃机输出然后传递给副轴的扭矩传递到与副皮带轮的副轴同轴设置的最终减速装置的减速装置; 以及设置在副轴和减速装置的输入轴之间的阻尼器油室。 由于输入驱动力而在减速装置中产生的推力被传递到阻尼油室中的液压流体,然后被吸收。 因此,抑制了初级带轮和次级带轮之间的相对位置的位移。

    • A flow control valve is provided in a primary pulley that is a rotor, and includes a first port; a second port; a working fluid channel formed between the first port and the second port and through which working oil passes; a check valve that is formed in the working fluid channel and is opened toward a first-port-side channel from a second-port-side channel of the working fluid channel; and a valve-opening control section (a guide member, a spool, a cylinder, and a drive pressure chamber) that is arranged at the check valve at the side of the second port, that forcibly opens the check valve when discharging the working fluid from the first port to the second port, and increases a channel resistance of the second-port-side channel as an opening amount of the check valve is small. The flow control valve can prevent over-discharge of the working fluid at the beginning of opening the valve.
    • 流量控制阀设置在作为转子的主带轮中,并且包括第一端口; 第二个港口 在第一端口和第二端口之间形成的工作流体通道,工作油通过该工作流体通道; 止回阀,其形成在工作流体通道中并且从工作流体通道的第二端口侧通道朝向第一端口侧通道打开; 以及布置在第二端口侧的止回阀处的开阀控制部(引导部件,阀芯,气缸和驱动压力室),当排出工作流体时强制打开止回阀 从第一端口到第二端口,并且随着止回阀的打开量小,第二端口侧通道的通道电阻增加。 流量控制阀可以防止在开启阀门时工作流体的过度排放。
