Abstract:
(EN) [Problem] To provide an electric booster device that is more compact and lightweight. [Solution] In this electric booster device 1, a housing 3 is provided with: a rear housing 23 comprising a vehicle mounting plate 27; a front housing 20 disposed between a master cylinder 15 and the rear housing 23; and coupling members 17 for coupling the master cylinder 15 and the rear housing 23, with the front housing 20 therebetween. When hydraulic pressure is generated in the master cylinder 15, the hydraulic reaction force from the master cylinder 15 is thus transmitted to a first rear housing part 23A via the coupling members 17, thereby making it possible to reduce the rigidity of the front housing 20. This makes it possible to make the electric booster device 1 more compact and lightweight.
(FR) Le problème décrit par la présente invention est de fournir un dispositif d'amplification électrique qui est plus compact et léger. La solution selon la présente invention porte sur un dispositif d'amplification électrique (1) comprenant un logement (3) pourvu : d'un logement arrière (23) comprenant une plaque de montage de véhicule (27) ; d'un logement avant (20) disposé entre un maître-cylindre (15) et le logement arrière (23) ; et d'éléments d'accouplement (17) pour accoupler le maître-cylindre (15) et le logement arrière (23), avec le logement avant (20) entre eux. Lorsqu'une pression hydraulique est générée dans le maître-cylindre (15), la force de réaction hydraulique provenant du maître-cylindre (15) est ainsi transmise à une première partie de logement arrière (23A) par l'intermédiaire des éléments d'accouplement (17), ce qui permet de réduire la rigidité du logement avant (20). Cela permet de rendre le dispositif d'amplification électrique (1) plus compact et léger.
(JA) 【課題】小型・軽量化した電動倍力装置を提供する。 【解決手段】本電動倍力装置1では、ハウジング3は、車両への取付プレート27を有するリアハウジング23と、マスタシリンダ15とリアハウジング23との間に設けられるフロントハウジング20と、該フロントハウジング20を介して、マスタシリンダ15とリアハウジング23とを結合する結合部材17と、を備えている。これにより、マスタシリンダ15における液圧発生時、マスタシリンダ15からの液圧反力が、結合部材17を介して第1リアハウジング部23Aに伝達されるので、フロントハウジング20の剛性を低くすることができる。これにより、電動倍力装置1の小型・軽量化を達成することができる。
