Abstract
The utility model discloses a transmission shaft end cross-linked coupling combined structure, which comprises transmission shafts and cross-linked couplings connected with two ends of the transmission shaft. The phase angle theta between the cross-linked couplings at two ends of the transmission shafts is more than or equal to 90 degrees and less than or equal to 0 degree. The utility model breaks through the connection thinking mode of the conventional cross-linked coupling, solves the problem of the vibration of the transmission shafts, simultaneously does not change the angle between the transmission shafts and the working speed of the transmission shafts, and ensures that the vibration amplitude is greatly reduced, and the vibration amplitude of the structure reaches over three fourths of the prior proposal. The proposal is simple and feasible. The transmission shaft end cross-linked coupling combined structure is suitable for connection of a plurality of shafts.
Description
Technical field
The utility model belongs to automobile component, specifically a kind of new Hooke's joint composite structure that can effectively solve transmission shaft running vibration.
Background technique
Cardan universal joint is simple in structure because of it, reliable transmission, and the efficient height, with low cost, and allow that bigger angle is arranged between two transmission shafts, so be widely used in the power train of all kinds of automobiles.But because the variable speed of cardan universal joint, promptly its output speed has the characteristics of cyclic fluctuation, easily causes the vibration in the transmission shaft working procedure, causes the resonance of other parts of car load when serious.Car load self causes that two big roots of vibration are motor and transmission shaft at present.Tradition cardan universal joint coupling all adopts coplanar or is arranged vertically mode when mounting arrangements, and promptly the phase angle θ between the cardan universal joint coupling at transmission shaft two ends is 0 ° and 90 ° (as shown in Figure 1, 2).The transmission shaft of this composite structure often causes bigger vibration in actual use, influences the travelling comfort of vehicle and the working life of parts.And the simple device that does not have other now can realize not changing the angle between two transmission shafts, can avoid bigger vibration simultaneously.This problem perplexs those skilled in the art always.
Summary of the invention
The purpose of this utility model is to provide a kind of new cross coupler composite structure, to address the above problem.
The technical solution of the utility model is: composite structure of transmission shaft end cross coupling, it comprises transmission shaft, the cardan universal joint coupling that the transmission shaft two ends connect, the phase angle θ between the cardan universal joint coupling at transmission shaft two ends is in following scope: 0 °＜θ＜90 °.
Phase angle θ between the cardan universal joint coupling at described transmission shaft two ends is in following scope: 0 °＜θ≤15 °.
Phase angle θ between the cardan universal joint coupling at described transmission shaft two ends is in following scope: 25 °≤θ＜90 °.
The utility model is exactly a variable speed characteristic of utilizing the cross coupler output speed, by adjusting the relative phase angle between cross coupler, output speed variable speed characteristic between a plurality of cross couplers is cancelled out each other, thereby reach and transmission shaft is exported variable speed reduce to minimumly, and the transmission shaft Oscillation Amplitude is reduced to minimum the most at last.It has broken through the mode of thinking of traditional solution vibration, does not change the angle between the transmission shaft, does not change the transmission shaft working speed, and transmission shaft operational vibration amplitude is declined to a great extent.This scheme is simple.It is suitable for the connection of many transmission shafts.

Embodiment
The inventor is utilizing the variable speed characteristic of cross coupler output speed, in the structure that does not change the cardan universal joint coupling, do not change under the condition of the angle between the transmission shaft, it is different that the cardan universal joint coupling of an axle head of transmission shaft keeps, change another the angle of cardan universal joint coupling of transmission shaft, promptly change phase angle θ between the cardan universal joint coupling at transmission shaft two ends (as Fig. 3, shown in 4), when finding that phase angle θ between the cardan universal joint coupling at transmission shaft two ends is between 0 °＜θ≤15 ° and 25 °≤θ＜90 °, transmission shaft operational vibration amplitude reduces maximum, and vibration decreases by more than 3/4ths of former scheme.
