32.9 Single combined torque-thrust reaction member,with springs taking only vertical and lateral loads
This form of construction is shown in Fig.32.6 Bolted to the axle casing A and surrounding the propeller shaft is a tubular member B,the front end of which,C,is spherical and fits in a cup D bolted to a cross-member of the frame,or to the back of the gearbox.The springs are bolted to seats pivoted on the axle casing,and at each end are shackled to the frame.Clearly the member B will transmit the thrust from the axle to the frame and will also take the torque reaction.Since the centre line of the bevel pinion shaft will always pass through the centre of the spherical cup,if the propeller shaft E is connected to the gearbox shaft F by a universal joint situated exactly at the centre of that cup,neither an additional universal joint nor a sliding joint will be necessary,since both pinion shaft and propeller shaft will move about the same centre,namely that of the spherical cup,when the axle moves up or down.Because the axle is constrained to move about the centre of the spherical cup,the springs of course have to be shackled at each end to allow for the variation of their camber with deflection.
An alternative to the ball-and-cup construction is shown in Fig.32.7.The tubular member B is again bolted to the axle casing at its rear end,but at the front it has pivoted on it a forked member A which is pivoted on pins C carried by brackets riveted to a cross-member of the frame.By pivoting on the pins C the axle can move about the axis XX,both rear wheels moving up or down together,while by the tube B turning in the bracket A about the axis YY,one rear wheel can move up without the other.The universal joint must have its centre at O,the intersection of the axes XX,YY.
In this system the spring seats are sometimes articulated on spherical
bearings on the axle casing,to relieve the springs of twisting stresses.The same advantage was sought in some early designs by attaching the spring shackles to the frame on a pivot whose axis was parallel to the centre line of the frame.
32.9单一的结合反应,部件仅仅承担了横向和纵向弹簧负载
结构形式如图32.6所示,管状部件B环绕传动轴,并通过螺栓连接到驱动桥壳A上.它的前部末端C是球状的,装配在罩D内,D是通过螺栓连接到车架横梁或着变速器后端的.座位的弹簧用螺栓固定在轴上能转动套管,每一结束,被家传的框架.明确会员B传达从轴推力的框架和也会转矩的反应.自从中线的斜齿轮轴总是通过中心球形杯,是不是螺旋桨轴E连接到齿轮箱轴外的万向节正好在中心位于这杯,也没有额外的万向节滑动,也共同将是必要的,因为两者都有齿轮轴和螺旋桨轴就采取相同的中心,即球形杯上,当轴移动上升或下降.因为轴制约中心行动球形杯、课程泉两端各被以允许他们的曲面变化偏转.
可替代的施工ball-and-cup.32.7米列图.管状成员B是再用螺栓固定轴套管后背结束,但是在前面有一个能转动开叉的成员能转动的头皮C所携带的cross-member铆接,支架的框架.在旋转的针C轴想走动轴XX,两后轮上下移动在一起,在被管B逐渐在支架大约轴YY,一后轮可以选用结伴而行的.必须保持他们的万向节十字路口啊,那中心轴线的XX,YY.
在这个系统中,弹簧支座铰接在桥壳上的球轴承内,从而减少弹簧的扭应力.在早期的设计中,把弹簧钩环固定到车架的枢轴上,其轴线与车架的中心线平行,同样可以有减少弯曲应力的优点.
