The invention discloses a speed reducer, a control method thereof and an electric off-road vehicle provided with the speed reducer, a shifting fork control system on one side of a main speed reduction gear shaft of the speed reducer controls a shifting fork to drive a gear sleeve, the gear sleeve pushes connecting teeth to do reciprocating motion in the axis direction, and through meshing and separation of canine teeth of the connecting teeth and a gear ring of a half axle gear, the speed reducer is driven to rotate. And the connecting teeth are jointed with the inner spline and the outer spline of the joint gear sleeve, so that the differential mechanism is disconnected, jointed and locked. The differential locking function in a four-wheel drive mode and a cross-country mode is achieved, meanwhile, decoupling of a non-drive speed reducer and wheels in a two-wheel drive mode can be achieved, the differential locking device better adapts to the cross-country working condition and the level road working condition, abrasion of electric drive components is reduced, energy consumption is reduced, and the cruising ability of the cross-country electric vehicle is enhanced.
本发明公开了一种减速器及其控制方法、安装有该减速器的电动越野车,减速器的主减速齿轮轴一侧的拨叉控制系统控制拨叉带动齿套,齿套推动连接齿沿轴线方向做往复运动,通过连接齿的犬齿与半轴齿轮的齿环的啮合与分离,以及连接齿与接合齿套的内、外花键接合,实现差速器的断开、接合与锁止。本发明不仅具备四驱模式及越野模式下的差速锁止功能,同时又能实现两驱模式下非驱减速器与车轮的解耦,更好地适应越野工况和平路工况,减少电驱部件磨损,节省能耗,增强越野电动车的续航能力。
