电动驻车系统的执行器
Abstract:
一种电动驻车系统的执行器，包括外壳、收容于外壳内的马达、行星轮机构、连接行星轮机构与马达的带轮机构，以及一隔离件，带轮机构包括间隔设置的主动轮、从动轮、以及环套主动轮与从动轮的传动带，主动轮与马达连接，从动轮与行星轮结构连接，隔离件包括第一间隔件、第二间隔件、以及缓冲件，第一间隔件相对主动轮的中心轴固定，第二间隔件相对从动轮的中心轴固定，第二间隔件位于第一间隔件的上方并沿轴向装配于第一间隔件上，缓冲件位于第二间隔件与外壳之间。本发明的执行器的带轮机构上设有隔离件用于确定主动轮和从动轮之间的中心距，并吸收马达以及行星轮机构的振动，执行器工作时噪音低，运行稳定、且整体结构简单、组装方便。
Abstract(English):

An actuator for an electric parking brake system includes an outer housing, a motor, a planetary gear mechanism and a belt-wheel mechanism that are received in the outer housing, and an isolation member. The belt-wheel mechanism includes a driving wheel, a follower wheel, and a transmission belt. The driving wheel is connected with the motor. The follower wheel is connected with the planetary gear mechanism. The isolation member has a first spacer fixed to the driving wheel via the motor, a second spacer fixed to the follower wheel, and a buffering element disposed between the second spacer and the outer housing. The second spacer is disposed above and assembled to the first spacer. The isolation member defines the center-to-center distance between the driving wheel and the follower wheel, and absorbs vibrations from the motor and the planetary gear mechanism.
