The invention discloses an integrated motor hydraulic brake which is composed of a transmission mechanism, a guide limiting mechanism, a brake master cylinder mechanism and a sealing mechanism. The transmission mechanism is composed of a motor, a motor gear, a first-stage driven gear, a second-stage driving gear, a second-stage driven gear and a lead screw. The guide limiting mechanism is composedof a limiting sliding rod, a guide rod, a limiting block, a front limiting nut and a rear limiting nut. The brake master cylinder mechanism is composed of a master cylinder ejector rod cover, a master cylinder ejector rod, a return spring and a brake master cylinder. Through motor driving and transmission of the transmission mechanism, rotary motion of the gear is converted into linear motion ofthe master cylinder ejector rod to push the brake mastecr cylinder piston to establish brake pressure. The lead screw is directly matched with the second-stage driven gear, so that a pedal, a lead screw nut and other components are removed, and the installation steps are simplified; the square outlet head of the lead screw is utilized, so that the lead screw only does linear motion; and by utilizing the sealing structure between the shells, the overall sealing performance is improved, so that the safety of the brake-by-wire system is improved.
本发明公开了一种集成式电机液压制动器,是由传动机构、导向限位机构、制动主缸机构和密封机构组成;传动机构由电机,电机齿轮、一级从动齿轮、二级主动齿轮、二级从动齿轮和丝杆构成;导向限位机构由限位滑杆、导向杆、限位块、前限位螺母和后限位螺母组成;制动主缸机构由主缸顶杆盖、主缸顶杆、回位弹簧和制动主缸组成。利用电机驱动,经传动机构的传动,将齿轮的旋转运动转化为主缸顶杆的直线移动进而推动制动主缸活塞建立制动压力。本发明将丝杆直接与二级从动齿轮配合,去除踏板、丝杆螺母等部件简化安装步骤;利用丝杆的方形出头,使丝杆只做直线运动;利用壳体之间的密封结构,增加了整体的密封性,从而提高了线控制动系统的安全性。
