| 摘要 |
The invention relates to a play take-up device (1) comprising a push button (10) that is movably mounted and translationally guided, along a thrust axis (ZZ'), in a housing (15, 16), to exert a thrust force (F) against a rack (2), said device (1) further comprising a resilient shock-absorbing member (20) that is positioned between the push button (10) and the housing (15, 16), in contact, respectively, against a first bearing surface (21) belonging to the push button (10), referred to as the "distribution surface" (21, 23), which is angled in relation to the thrust axis (ZZ'), and is preferably frusto-conical, and a second bearing surface (22) belonging to the housing (15, 16), referred to as the "seat surface" (22, 24), which has, opposite the distribution surface (21, 23) and counter to the resilient shock-absorbing member (20), both a radially extending component and an axially extending component, such that the shock-absorbing member (20) simultaneously returns the push button (10) axially towards the rack (2) and transversely towards the thrust axis (ZZ'). |
