The invention relates to a transmission device of an electronic hydraulic brake boosting and pressurizing mechanism, and belongs to the field of automobile brake. Three planetary gears are in clearance fit with three protruding positioning pins of the nut and meshed with the planetary wheel ring, the nut and the bearing are in transition fit, the positioning ring is supported behind the bearing, the protective ring and the positioning ring are welded into a whole through laser, the nut, the steel ball and the lead screw are assembled into a ball screw mechanism, and the anti-rotating pin is in clearance connection with the lead screw. The rear end of the push rod head is in interference fit with the lead screw into a whole, the front end of the push rod head is matched with the piston through a spherical slope, the spring seat is riveted with the piston into a whole through rolling, and the spring is sleeved outside the spring base. The device has the advantages of being novel in structure, high in efficiency, high in reliability and low in cost, replacing a traditional vacuum source with the motor serving as a power source, changing rotary motion into linear motion, providing assistance for braking of a driver, being capable of achieving active starting and providing braking force for a vehicle, and being a trend of development of a future service braking system.

    本发明涉及一种电子液压制动助力增压机构的传动装置,属于汽车制动领域。三个行星齿轮与螺母凸出的三个定位销间隙装配,并与行星轮圈相互啮合,螺母与轴承过渡装配,定位环在轴承后方支撑,护圈与定位环激光焊接为一体,螺母、钢珠、丝杆装配为滚珠丝杆机构,防转销与丝杆间隙连接,推杆头后端与丝杆过盈装配为一体、前端与活塞通过球形斜面相配合,弹簧座与活塞通过滚动铆接为一体,弹簧套接弹簧座外部。优点是结构新颖,使用电机作为动力源代替传统真空源,将旋转运动变化为直线运动,为驾驶员制动提供助力,效率高,可靠性强,成本低,可实现主动启动,为车辆提供制动力,是未来行车制动系统发展的趋势。
