The outer ring two in second ball cage joint and the reel end face tooth between middle spindle nose mesh together; Reel connects through spline pair with middle spindle nose; On the cylindrical of middle spindle nose, the end of reel is equipped with the intermediate support device, intermediate support device and reel are filled up circle ﹑ lock washer and round nut axially locating;
Steel pipe and the weldering of middle axle sleeve are one in the middle of the middle spindle nose ﹑, and there is spline protecting cover two outside of middle axle sleeve, spline protecting cover two; An end through the end cap two that has been threaded, spindle nose two is arranged in the internal spline of middle axle sleeve, the splined shaft of the other end of spindle nose two is connected with the inner ring three in the 3rd joint; Three of outer ring three and inner rings are equipped with retainer three, on outer ring three and the inner ring three many raceway grooves that equidistantly distribute along circumference are arranged, and steel ball three is housed between the raceway groove; Steel ball three is installed in the window of retainer three; Sealing system is equipped with in three of outer ring three and outer rings, and inner ring three and spindle nose two are connected through spline, and there are back-up ring five and back-up ring six axially locating in two ends;
Between the support of said intermediate support device and the middle spindle nose bearing is housed.
The spline pair at disarthrial two ends can endwisely slip separately; Can compensate the angle that turns to and take turns jumping of vehicle simultaneously; Can have two different extending amounts to satisfy two different angle compensations, method fixes ball cage coupling to the limit speed that improves coupling simultaneously with adopting flexibly.
The utility model compared with prior art has the following advantages:
1, increases auxiliary intermediate support, can effectively improve the limit speed of ball cage coupling;
2, can fix ball cage coupling with method flexibly, such as, adopt ball cage outer ring, two ends and intermediate support to fix the ball cage, the position of intermediate support device border factually needs flexible arrangement, makes ball cage coupling that wideer application area and field arranged;
3, replace the function of two cover ball cage coupling (4 joints) with a cover ball cage coupling, more save installing space, reduce Zhi Zao ﹑ and install and maintenance cost.
