Abstract
The utility model relates to a combined transmission shaft assembly used for connecting, which comprises a flange fork, an axle casing of a transmission shaft and a spline shaft; wherein, a sliding fork is arranged between the flange fork and the axle casing of the transmission shaft; the structure of one end of the sliding fork is matched with the flange fork to form a crisscross gimbal hole, and the other end has a cylindrical shape which is connected with the axle casing of the transmission shaft by outer and inner splines; the back end of the spline shaft is extended with a cylindrical shape which is connected with the other end of the axle casing of the transmission shaft by outer and inner splines. The combined transmission shaft assembly applies the manner of spline connection to design connecting structure of all the parts of the transmission shaft assembly and uses a sliding fork to replace the former welding fork; besides, as a plurality of components are connected in separating detachable way, a certain damaged component can be replaced conveniently. Furthermore, the structure can reduce the type requirements caused by the length of the axle casing of the transmission shaft, so the structure is convenient for the user to choose.
Description
Technical field
The utility model belongs to a kind of actuating unit, relates in particular to a kind of intermediate propeller shaft of being made up of flange yoke, weld yoke, splined shaft, cardan-shaft tube or the linkage structure of front propeller shaft assy..
Background technique
Truck drive shaft is the vitals that connects speed changer and ransaxle in the automotive transmission, it constitutes the universal driving device of automotive transmission with parts such as universal joint assemblies, it mainly acts on is to be used to connect the not diaxon on same straight line, and guarantees that power transmits between them reliably.The transmission shaft quantity that various vehicles use does not wait, and in general speed changer and ransaxle spacing use a transmission shaft get final product more in short-term, still, if when spacing is big, just need the increase front propeller shaft, and intermediate propeller shaft.The structure of front propeller shaft and intermediate propeller shaft is corresponding to, is made of flange yoke, weld yoke, splined shaft, cardan-shaft tube four parts.During assembling, by electric welding weld yoke, splined shaft, cardan-shaft tube three are fixed into integral body, then, rely on the fixedly spline of splined shaft to stretch in the internal spline of flange and realize connecting, both connect with spline and cooperate, and carry out the transmission of moment of torsion.The problem that prior art exists is: the transmission shaft model is various, different in size, makes manufacturer, dealer and user feel very inconvenient; Cardan-shaft tube, weld yoke and splined shaft three part electric welding are fixed into integral body, in case some damage will be brought disaster to other, whole transmission shaft can only be done to scrap to have handled, and not only increased cost to the user, also wasted resource.
Summary of the invention
For overcoming above shortcomings in the prior art, the utility model aims to provide a kind of combined type connection driving-shaft assembly with new structure, even damaging, certain part of this assembly can not bring disaster to other yet, can also continue to use after changing broken parts, help alleviating user cost, economize on resources.
For achieving the above object, the utility model has adopted following technological scheme: this combined type connects and comprises flange yoke, cardan-shaft tube, splined shaft with driving-shaft assembly, it is characterized in that: be provided with a slip yoke between flange yoke and the cardan-shaft tube, the structure and the flange yoke of slip yoke one end are complementary, form the universal knothole of cross, the other end is cylindrical, and cylindrical and cardan-shaft tube is that interior external splines links; The splined shaft rear end prolongs and one cylindrically, and this cylindrical and the other end cardan-shaft tube are that interior external splines links.
Described this combined type connects uses driving-shaft assembly, and it is characterized in that: the transmission shafts inner tube wall is provided with spline, and slip yoke is cylindrical to be provided with the free-sliding spline that is complementary with transmission shafts inner tube wall spline with the columniform outer wall of splined shaft.
Described this combined type connects uses driving-shaft assembly, and it is characterized in that: the cardan-shaft tube outer wall is provided with spline, and slip yoke is cylindrical to be provided with the free-sliding spline that is complementary with cardan-shaft tube outer wall spline with the columniform inwall of splined shaft.
Beneficial effect: compared with prior art, splined mode designs the each several part linkage structure of intermediate propeller shaft or front propeller shaft assy., substitute original weld yoke with a slip yoke, and after several parts are the detachable connection of split, in case certain parts damages can be changed easily.In addition, this structure can also reduce the model requirement that causes because of the transmission shafts length of tube, makes things convenient for the user to select.
For the utility model technology contents that sharpens understanding, be described further below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is an embodiment's of the utility model an assembly structure schematic representation.
Embodiment
Sequence number is represented respectively among the figure: flange yoke 10, and fixed hole 11, universal knothole 12, slip yoke 20, slip yoke free-sliding spline 21, central siphon 30, central siphon internal spline 31, equilibrium block 32, splined shaft 40, fixedly spline 41, fixing bolt 42, splined shaft free-sliding spline 43.
Referring to Fig. 1.This combined type connects with driving-shaft assembly and comprises flange yoke 10, slip yoke 20, cardan-shaft tube 30, splined shaft 40 4 parts composition.Flange yoke 10 is connected with gear box flange by bolt through four fixed holes 11, and flange yoke 10 has two universal knotholes 12 up and down corresponding to slip yoke 20 one side, and slip yoke 20 is complementary with it, about two universal knotholes are set.The other end of slip yoke 20 is cylindrical, and columniform periphery is provided with slip yoke free-sliding spline 21 (when external splines is set, cylindrical with entity for well), and the central siphon internal spline 31 of this free-sliding spline and cardan-shaft tube 30 is matched.Splined shaft 40 front-end architectures are consistent with original structure, and its rear end prolongs and one cylindrically, and the cylindrical structural on this columniform shape and structure and the slip yoke 20 is consistent, and external splines connects in realizing with the other end of cardan-shaft tube 30.
Cylindrical length on above-mentioned slip yoke 20 and the splined shaft 40 generally can be 1/3rd length of cardan-shaft tube 30.
In the specific implementation, except that considering that is: on cardan-shaft tube 30 inwalls, central siphon internal spline 31 to be set, and free-sliding spline is set with splined shaft on cylindrical in that slip yoke is cylindrical, to reach the transmitting torque purpose with the above-mentioned scheme.But, also can be according to actual conditions, adopt and on cardan-shaft tube 30 outer walls, the central siphon external splines be set, and with slip yoke the cylindrical and cylindrical pipe that makes into of splined shaft, the free-sliding spline that is complementary with cardan-shaft tube outer wall spline is set on inwall.
