A parking brake assembly includes a disc defining an aperture and a ramp located proximate the aperture; a pedal configured to rotate the disc in a locking direction or an unlocking direction; and an actuator including a body and a spring biased to urge the body toward the aperture, the actuator further including a pin positioned and arranged to travel along the ramp when the disc is rotated relative to the actuator, where the pin is displaced along the ramp when the disc is rotated in the locking direction. The spring is allowed to push the body through the aperture and into a mating hole of the wheel or associated with the wheel such that the pin travels downward along the ramp, and wherein, when the disc is rotated in the unlocking direction, the spring is prevented from pushing the body through the aperture and into the mating hole such that the pin travels upward along the ramp.
一种驻车制动组件,包括:盘,其限定孔口和位于孔口附近的斜面;踏板,其被构造成在锁定方向或解锁方向上使盘旋转;以及致动器,其包括主体和弹簧,弹簧被偏压以朝向孔口推动主体,致动器还包括销,销被定位和布置成当盘相对于致动器旋转时沿着斜面行进,其中,当盘在锁定方向上旋转时,弹簧被允许推动主体穿过孔口并且进入车轮的或与车轮相关联的配合孔中,使得销沿着斜面向下行进,并且其中,当盘在解锁方向上旋转时,弹簧被阻止推动主体穿过孔口并且进入配合孔中,使得销沿着斜面向上行进。
