Abstract
The utility model belongs to the technical field of automobile drive accessories and provides an output connection structure of an external constant velocity universal joint. The output connection structure of the external constant velocity universal joint comprises a housing, a retainer, a steel ball and a starlike sleeve, wherein the retainer, the steel ball and the starlike sleeve are all arranged inside the housing, the housing is connected with an output shaft, the steel ball can rotate around a rail inside the starlike sleeve to drive the output shaft to swing correspondingly, and the swinging angle is 20-45 degrees. The output connection structure of the external constant velocity universal join has the advantages that the steel ball can rotate around the rail inside the starlike sleeve to drive the output shaft to swing correspondingly at a swinging angle of 20-45 degrees, so that the drive working angle is large, the working efficiency is high, and the possibility of the external constant velocity universal joint driving on irregular road surfaces is largely improved; two splines enable the connection of the output shaft with other accessories much firmer, thereby better transmitting torque and movement and improving the bearing capacity of a drive shaft assembly; and a flat gasket is arranged at the position of a lock nut, so that the stability and the reliability of the connections between the output shaft and other parts are guaranteed.
Description
Technical field
The utility model belongs to Automobile drive accessory technical field, relates to a kind of output connecting structure of external ball cage.
Background technique
In order to make the automobile power transmission, all can use drive shaft assembly, adopting at present maximum is the Rzeppa type drive shaft assembly, has all solved preferably constant speed transmission problem no matter this kind drive shaft assembly is circular arc alley or liner ball road, and it is large to transmit operating angle, and efficient is high.The output connecting structure of the external ball cage in existing drive shaft assembly is directly output terminal to be connected with other accessory, and shortcoming is: can not adapt to complicated pavement state, and a bit unable to do what one wishes when facing high pulling torque.
Summary of the invention
Technical problem to be solved in the utility model is the present situation for prior art, and provides a kind of simple in structure, and the output bearing capacity is good, the output connecting structure of the external ball cage that working stability is strong.
The utility model solves the problems of the technologies described above the technological scheme that adopts: a kind of output connecting structure of external ball cage, comprise housing and be arranged on the interior retainer of housing, steel ball and star sleeve, be connected with output shaft on described housing, it is characterized in that, described steel ball can be in star sleeve orbit rotation, described output shaft swings relatively when steel ball rotates, and the angle that swings is controlled between the 20-45 degree.
Here the angle that swings is controlled between the 20-45 degree, satisfied like this needs of specific vehicle big swing angle, and bearing capacity is strong, greatly improve use this external ball cage on irregular ground up possibility of sailing.
Specifically comprise for optimizing the such scheme Adopts measure:
At the output connecting structure of above-mentioned a kind of external ball cage, offer respectively the first spline and the second spline on described output shaft, be fixed with locking nut on the close end of output shaft, at the other flat gasket that is provided with of locking nut.
At the output connecting structure of above-mentioned a kind of external ball cage, the length of described the first spline is greater than the length of the second spline, and the vertical width of output shaft at described the first spline place is greater than the vertical width of output shaft at the second spline place.Here to make output shaft be connected with internal spherical cage more firm with being connected spline by the first spline, transmitting torque and motion better, improve the bearing capacity of drive shaft assembly, gone out to install flat gasket in locking nut simultaneously, guaranteed the reliability that output shaft is connected with other parts.
At the output connecting structure of above-mentioned a kind of external ball cage, be provided with bearing on the tail end of described output shaft.
compared with prior art, the utility model has the advantage of the orbit rotation that steel ball can be in star sleeve, described output shaft swings relatively when steel ball rotates, and the angle that swings is controlled between the 20-45 degree, the transmission operating angle is large, efficient is high, greatly improve to use this external ball cage on irregular ground up possibility of sailing, two splines make output shaft be connected more firm with other accessory, transmitting torque and motion better, improved the bearing capacity of drive shaft assembly, simultaneously go out to install flat gasket in locking nut, guaranteed the reliability that output shaft is connected with other parts.
