In order to solve the technical problems that when a bearing element (also called as a guide rod) of an existing brake booster is assembled, the assembly consistency is difficult to guarantee, the reliability of an overall product is affected, and the production and assembly efficiency is low, the invention provides a shell for the brake booster. The shell comprises an upper end cover, a middle shell and a bottom shell which are connected in sequence; at least one guide structure is arranged on the side wall of the middle shell and is parallel to the axial direction of an electric push rod ofthe brake booster; and the guide structure is an inner guide structure and/or an outer guide structure. The at least one guide structure is arranged on the side wall of the brake booster shell, and the guide structure and a shell body are integrally formed, so that the consistency of the guide structure is effectively ensured, and the stability and the reliability of the product are improved. Thelink of independently assembling the guide rod of the brake booster is omitted, the production efficiency is improved, and the manufacturing cost is reduced.

    为了解决现有制动助力器其承载元件(也称导杆)在装配时,很难保证装配一致性,从而影响整体产品的可靠性,以及生产和装配效率较低的技术问题,本发明提供了一种制动助力器用壳体,包括依次连接的上端盖、中间壳体和底壳;中间壳体的侧壁上设置至少一个导向结构,该导向结构与制动助力器的电动推杆的轴向平行;导向结构为内导向和/或外导向结构。本发明制动助力器壳体的侧壁上设置有至少一个导向结构,该导向结构与壳体本体一体成型,有效保证了导向结构的一致性,提高了产品的稳定性和可靠性。本发明使得制动助力器整体产品省去了单独装配导杆的环节,提高了生产效率,降低了制造成本。
