根据某高速轮式工程机械传动系统必须停车才能实现高低挡位切换和变速操纵繁琐的问题,设计研制一种新型全动力换挡变速器。用高低挡换挡离合器总成取代原变速器拨叉啮合套结构,使机械不停车即可实现高低挡位的切换。与原变速器相比,采用在同一根轴上背靠式布置双离合器的结构形式,在增加两个离合器的情况下,实现离合器的全内置布置,解决了新旧变速器的原位换装问题;变速操纵杆由3根减少到2根,进一步提高机械的机动性能和操纵性能。
According to a high-speed wheeled mechanical transmission system must be parked in order to achieve high and low gear shift and speed control tedious issues, the design and development of a new full power shift transmission. High and low gear shift clutch assembly to replace the original transmission fork clutch sleeve structure, so that the machine can be achieved without stopping the level gear shift. Compared with the original transmission, the double-clutch structure with back-to-back arrangement on the same shaft is adopted. With the addition of two clutches, the full-built clutch arrangement is realized, which solves the problem of the original transmission of the old transmission and the old transmission. Reduced from 3 to 2 joysticks, to further improve the mechanical performance and maneuverability.
