Lead screw braking device for vehicle automatic doors
The invention discloses a lead screw braking device for vehicle automatic doors. The device comprises a driving motor, and a lead screw transmission mechanism, wherein a braking box is arranged between the driving motor and the lead screw transmission mechanism, and the braking box comprises a braking box body, a main brake, an auxiliary brake, an unlocking disc and a transmission main shaft. Thevehicle automatic doors realize opening and locking through the lead screw transmission mechanism, and a rotary damper between the main brake and the unlocking disc in the braking box randomly controls separation and engagement between the main brake and the auxiliary brake, so that opening and locking of the vehicle automatic doors are controlled, and the damping performance is kept stable and unchanged in the long-time operation process; and the lead screw braking device for the vehicle automatic doors realizes braking of the lead screw transmission mechanism with high reliability in a limited space, and is suitable for passenger car automatic doors, rail transit vehicle automatic doors and platform automatic doors, and has a good application prospect.
本发明公开了一种用于车辆自动门的丝杠制动装置，该装置包括驱动电机、丝杠传动机构，驱动电机和丝杠传动机构之间设置有一个制动箱，该制动箱包括制动箱体、主制动器、副制动器、解锁盘、传动主轴；车辆自动门通过丝杠传动机构实现开启和锁闭，制动箱中的主制动器和解锁盘之间的转动阻尼器随机控制主制动器和副制动器之间的分离与啮合，从而控制车辆自动门的开启和锁闭，并在长时间运行过程中保持阻尼性能稳定不变。本发明实现了有限空间内高可靠性的丝杠传动机构的制动；适用于客车自动门、轨道交通的车辆自动门、站台自动门，具有良好的应用前景。
