本發(fa)明涉及一種汽(qi)配制動(dong)部件，具體是指電動(dong)助力制動(dong)裝置，可(ke)用于電動(dong)汽(qi)車(che)(che)、混合動(dong)力汽(qi)車(che)(che)、無(wu)人駕(jia)駛汽(qi)車(che)(che)或智能駕(jia)駛汽(qi)車(che)(che)等領域。

背景技術：

傳統內燃(ran)(ran)機汽車(che)(che)的(de)(de)制(zhi)動(dong)系統大多采用真(zhen)空助(zhu)力(li)裝置來協(xie)助(zhu)駕駛者(zhe)產生足夠的(de)(de)制(zhi)動(dong)力(li)，而(er)真(zhen)空源(yuan)來自于發(fa)動(dong)機或機械真(zhen)空泵。對(dui)于新能源(yuan)汽車(che)(che)（燃(ran)(ran)料電池汽車(che)(che)和純電動(dong)車(che)(che)）來說，沒有發(fa)動(dong)機來提供真(zhen)空動(dong)力(li)源(yuan)來提供制(zhi)動(dong)助(zhu)力(li)，僅由人力(li)所產生的(de)(de)制(zhi)動(dong)力(li)是無法滿足行車(che)(che)制(zhi)動(dong)的(de)(de)需求。電動(dong)助(zhu)力(li)制(zhi)動(dong)裝置可(ke)以很(hen)好的(de)(de)滿足這種需求。

近幾(ji)年，各大(da)汽車及零部件(jian)廠商相繼推出(chu)了(le)相似的(de)電子液壓制(zhi)動(dong)(dong)系(xi)(xi)統。通過檢索，德國(guo)博世公(gong)司(si)在ESP HEV制(zhi)動(dong)(dong)系(xi)(xi)統的(de)基礎(chu)上(shang)推出(chu)了(le)全新的(de)電子液壓制(zhi)動(dong)(dong)系(xi)(xi)統，參(can)見中國(guo)專(zhuan)利公(gong)開號(hao)CN103818371A。該(gai)電子液壓制(zhi)動(dong)(dong)系(xi)(xi)統的(de)結構(gou)包括有踏板模擬器(qi)、電動(dong)(dong)助(zhu)力(li)器(qi)、制(zhi)動(dong)(dong)泵總成等機構(gou)，但(dan)是其(qi)存在以下問題：
