In addition, when using the universal joint transmitting dress for being fixedly connected with rzeppa joint with driving shaft 8 by flange arrangement
When setting transfer motion power, power transfer path are as follows: power transmits flange arrangement by driving shaft 8, and passes to through flange arrangement extraterrestrial
Then wheel 2 passes to interior star-wheel 1 by steel ball 3, then passes to driven shaft through interior star-wheel 1.And it uses and is provided with the present invention in fact
When the universal joint transfer device transmitting power of the rzeppa joint of example offer is provided, power transfer path are as follows: power is by driving shaft 8
Interior star-wheel 1 is passed to, out star wheel 2 is then passed to by steel ball 3, then passes to driven shaft through out star wheel 2.Obviously, it uses
When being provided with the universal joint transfer device transmitting power of rzeppa joint provided in an embodiment of the present invention, power transfer path is wanted
Short, the component that power is passed through is few, thus can improve the power transmission efficiency of card gear, and improves universal joint biography
The dynamic balance performance of dynamic device, so as to improve the dynamic property of automobile.
Furthermore when rzeppa joint provided in an embodiment of the present invention is applied to card gear, when installation,
The splined shaft of driving shaft 8 need to only be passed through to the through-hole 71 of end cap 7, the centre bore of osculum positioning section 51 and big mouth positioning section 52
Centre bore is inserted into the splined hole 11 of interior star-wheel 1, is then adjusted to expansion sleeve 5 and end cap 7, with existing skill
Make rzeppa joint compared with when driving shaft 8 is fixedly connected by flange arrangement in art, without realizing fixation by bolt
When connecting, positioned without multiple clips are added to driving shaft 8, thus reducing needed for installation steps and installation
Between, and the use of component is reduced, therefore facilitate the installation of card gear, improve the assembly of universal joint transmission device
Efficiency, and can reduce the installation gap of card gear, improve the assembly precision of card gear.
Fig. 2 and Fig. 5 are please referred to, in the above-described embodiments, on expansion sleeve 5, along the circumferential uniform intervals of osculum positioning section 51
Multiple first strip gabs 53 are offered, offer multiple second strip gabs along the circumferential uniform intervals of big mouth positioning section 52
