本申请提出了一种电动制动助力器的输入推杆、维修装置和维修方法,该电动制动助力器的输入推杆包括依次固定连接的第一连接段、防尘段、主体段和第二连接段,其中,在所述主体段上设置有轴向延伸到所述防尘段的导气通道,所述导气通道的开口于所述第二连接段处开放,并在所述防尘段上设置连通孔,所述连通孔用于连通导气通道和外界,可以通过导气通道和连通孔将外界气体输送到防尘罩,促动防尘罩变形后的恢复,用于解决防尘罩扭曲变形无法满足零部件NVH性能需求的问题。

    The invention provides an input push rod of an electric brake booster, a maintenance device and a maintenance method.The input push rod of the electric brake booster comprises a first connecting section, a dustproof section, a main body section and a second connecting section which are fixedly connected in sequence, and the main body section is provided with an air guide channel axially extending to the dustproof section; an opening of the air guide channel is opened at the second connecting section, a communicating hole is formed in the dustproof section and used for communicating the air guide channel with the outside, external air can be conveyed to the dustproof cover through the air guide channel and the communicating hole, and the dustproof cover is promoted to recover after deformation. The problem that distortion and deformation of the dust cover cannot meet the NVH performance requirements of parts is solved.
