The invention relates to the technical field of vehicle forgings, and discloses a vehicle speed reducer using an electromagnetic braking principle to assist in braking, the vehicle speed reducer comprises a protective shell, a braking cavity is formed in the protective shell, a braking shaft is fixedly connected in the braking cavity, and a metal magnetic plate is fixedly connected to the outer side surface of the braking shaft; the two ends of the brake shaft are fixedly connected with locking rings, and the interiors of the locking rings are fixedly connected with transmission shafts. According to the vehicle speed reduction device assisting in braking through the electromagnetic braking principle, the metal magnetic plate can bear electromagnetic force in an electromagnetic field, the metal magnetic plate can give force opposite to the rotating direction of the braking shaft under the action of the electromagnetic force, the rotating speed of the braking shaft can be reduced under the action of the opposite force, and braking speed reduction of a vehicle is successfully achieved; the metal magnetic plate and the brake shaft are integrated vehicle forgings which are forged by using a forging technology, so that friction force is not generated by deceleration brake between the metal magnetic plate and the brake shaft, and the purpose of non-wear brake is achieved.
本发明涉及车用锻件技术领域,且公开了一种利用电磁制动原理辅助刹车的车用减速装置,包括防护外壳,所述防护外壳的内部开设有制动腔,制动腔的内部固定连接有制动轴,制动轴的外侧表面固定连接有金属磁板,制动轴的两端固定连接有锁紧圈,锁紧圈的内部固定连接有传动轴。该利用电磁制动原理辅助刹车的车用减速装置,金属磁板在电磁场中会受到电磁力,在电磁力的作用下金属磁板会给与一个与制动轴转动方向相反的力,在反向力的作用下制动轴的转速会降低成功实现车辆的刹车减速,金属磁板和制动轴是利用锻造技术锻造出来的一体式车用锻件,所以之间的减速制动并不会产生摩擦力,实现了无磨损刹车的目的。
