Background technique
In order to make the automobile power transmission, all can use the ransaxle assembly, adopting maximum at present is Rzeppa type ransaxle assembly, has all solved constant speed transmission problem preferably no matter this kind ransaxle assembly is circular arc alley or liner ball road, and it is big to transmit operating angle, the efficient height.The total Chengdu of existing automobile drive axle is to be provided with the axostylus axostyle that connects universal joint in the middle of adopting the two ends universal joint, this design has just been considered the usability of ransaxle, and to material-saving joint consumption, it is thorough that the maintenance and installation aspect is not considered, in the driving process, needed to turn to effect owing to be in the universal joint of road wheel end, and the universal joint that is in the gearbox end just just produces slippage under the situation of Uneven road and the slippage scope is very little, so the wearing and tearing of road wheel end universal joint are beaten, life-span is low, be the parts that needs are often changed, whenever change three road wheel end universal joints according to statistics and just need change a gearbox end universal joint, again load onto car again and whenever tear next universal joint open, the maintenance step is more loaded down with trivial details usually, and the time is also long.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, and provides a kind of simple in structure, guarantees the improvement linkage structure of the ectosphere cage of ransaxle assembly operation stability.
The utility model solves the problems of the technologies described above the technological scheme that adopts: a kind of improvement linkage structure of ectosphere cage, comprise housing and be arranged on the interior retainer of housing, steel ball and star sleeve, be connected with output shaft on the described housing, it is characterized in that, be connected with jack shaft on the left end of described housing, be connected with left tie-plate and right tie-plate at jack shaft, be provided with bolt at right tie-plate, between left tie-plate and right tie-plate, be provided with jump ring.
The improvement of the utility model maximum is at jack shaft left tie-plate and right tie-plate to be set, like this when jack shaft damages, can dismantle easily and change, improve time efficiency greatly and reduced time cost, here the main effect of jump ring is to have increased the soundness that connects, and conveniently cushions.
The measure of taking for the optimization such scheme specifically comprises:
In the improvement linkage structure of above-mentioned a kind of ectosphere cage, be shaped on axially gradually open form spline on the described output shaft, be shaped on the braking gear ring on the described housing, at the other Sealing shield ring that is provided with of braking gear ring.
Here can strengthen control to car by the braking gear ring, when emergency braking, can keep operability significantly, reduce hydro-planing, shorten stopping distance effectively, Sealing shield ring can be blocked in the pollutant of outside outside the housing in addition, has improved the working life of ectosphere cage.
In the improvement linkage structure of above-mentioned a kind of ectosphere cage, dustproof body is installed on the described housing, described dustproof body has and alternately connects crest and trough, on dustproof body and be provided with clip between the housing.Here can guarantee that by clip dustproof body has certain resiliently deformable space, can increase the elastic force between dustproof body and the housing again relatively.
In the improvement linkage structure of above-mentioned a kind of ectosphere cage, described Sealing shield ring is the U font, and the length of described Sealing shield ring is 6～9mm.
In the improvement linkage structure of above-mentioned a kind of ectosphere cage, the described output bearing that axially gradually is connected with between open form spline and the housing, output bearing with axially gradually the open form spline be connected.Here improve the bearing capacity of ransaxle assembly by output bearing and axial gradually open form spline, guaranteed ransaxle assembly operation stability.
Compared with prior art, advantage of the present utility model is at jack shaft left tie-plate and right tie-plate to be set, like this when jack shaft damages, can dismantle easily and change, improve time efficiency greatly and reduced time cost, can strengthen control to car by the braking gear ring, when emergency braking, can keep operability significantly, reduced hydro-planing, shortened stopping distance effectively, Sealing shield ring can be blocked in the pollutant of outside outside the housing in addition, has improved the working life of ectosphere cage, whole ectosphere cage bearing capacity is strong, has guaranteed ransaxle assembly operation stability.
