阅读说明：本技术 扭转弹簧膨胀鼓式缓速离合器 (Torsion spring expansion drum type slow clutch ) 是由 苗春才 于 2019-11-01 设计创作，主要内容包括：该发明涉及汽车离合器技术领域。该扭转弹簧膨胀鼓式缓速离合器,其特征主要包括：弹簧摩擦套(1),弹簧衬套(2),泵油管(3),螺旋扭转弹簧(4),输入扭转盘(6),油缸通油孔(7),盘式扭转油缸(8)。若干螺旋扭转弹簧(4)平行盘绕若干圈在弹簧衬套(2)上并向内收紧。通过泵油管(3)和油缸通油孔(7)向盘式扭转油缸(8)空腔注入一定压强液压油,盘式扭转油缸(8)使弹簧衬套(2)相对输入扭转盘(6)顺时针扭转螺旋扭转弹簧(4)产生向外膨胀力。缓速控制液压油压强,螺旋扭转弹簧(4)与输出弹簧摩擦套(1)摩擦阻力缓速增加,输出弹簧摩擦套(1)与输入扭转盘(6)结合扭矩缓速增加,离合器能实现缓速离合。(The invention relates to the technical field of automobile clutches. This torsion spring expansion drum formula retarder clutch, its characterized in that mainly includes: the oil pump comprises a spring friction sleeve (1), a spring bushing (2), an oil pumping pipe (3), a spiral torsion spring (4), an input torsion disc (6), an oil cylinder oil through hole (7) and a disc type torsion oil cylinder (8). A plurality of helical torsion springs (4) are wound on the spring bushing (2) in parallel by a plurality of turns and tightened inwards. Hydraulic oil with a certain pressure is injected into a cavity of the disc-type torsion oil cylinder (8) through the oil pumping pipe (3) and the oil cylinder oil through hole (7), and the disc-type torsion oil cylinder (8) enables the spring bushing (2) to be relatively input into the torsion disc (6) to clockwise twist the spiral torsion spring (4) to generate outward expansion force. The pressure of hydraulic oil is slowly controlled, the frictional resistance of the spiral torsion spring (4) and the output spring friction sleeve (1) is slowly increased, the combined torque of the output spring friction sleeve (1) and the input torsion disc (6) is slowly increased, and the clutch can realize slow clutch.)
