Abstract
The utility model discloses a middle-connection-fork-type transmission shaft assembly comprising a front transmission shaft assembly and a rear transmission shaft assembly which are assembled and connected through a middle connection fork. A middle flange of a single-section front transmission shaft assembly and a flange fork of a single-section rear transmission shaft assembly in the prior art are replaced by a middle connection fork assembly, so that materials are saved, cost is lowered, dynamic balance of the middle-connection-fork-type transmission shaft assembly can be guaranteed, the phenomenon of balance overlapping of single-section dynamic balance of the front transmission shaft assembly and the rear transmission shaft assembly is eliminated, and quality of the middle-connection-fork-type transmission shaft assembly is improved.
Description
Technical field
The utility model relates to the auto parts machinery production technical field, is specifically related to connect the V shape driving-shaft assembly in a kind of.
Background technique
Along with growth in the living standard, people require to improve gradually to the travelling comfort of taking passenger vehicle.Except the upgrading of interior trim, the lifting of passenger-carrying chassis transmission shaft dynamic balancing quality also is a very important part.Two driving-shaft assemblies before and after passenger-carrying chassis generally uses, and the front and back driving-shaft assembly is single dynamic balancing (as shown in Figures 1 and 2), not only when assembling, need use many group bolts, nut to be connected the intermediate flange 1a of front propeller shaft assy. 1 and the flange yoke 2a of rear propeller shaft assy. 2 with pad, efficiency of assembling is extremely low, and the car load dynamic balancing is unsatisfactory after having entrucking, problems such as abnormal sound, resonance also take place, and the passenger feels very uncomfortable when taking.
The model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of technology simple, easy to assembly, and can eliminate the dynamically balanced balance superposition phenomenon of forward and backward driving-shaft assembly single-unit, connect the V shape driving-shaft assembly in the lifting driving-shaft assembly quality.
Connect the V shape driving-shaft assembly in a kind of, comprise front propeller shaft assy. and rear propeller shaft assy.; Connect by middle clevis assembling between described front propeller shaft assy. and the rear propeller shaft assy..
The front-end face of clevis leans against on the intermediate support assembly internal bearings of front propeller shaft assy. in the middle of described, and by nut, packing ring fixing and locking, the rear end of clevis is connected on the slip yoke assembly of rear propeller shaft assy. in the middle of described, and be connected with the universal-joint cross trunnion assembly of rear propeller shaft assy., fix by snap ring.
Weld yoke in the described front propeller shaft assy., middle splined shaft and central siphon interference fit and welding are fixing, the inner ring of intermediate support assembly internal bearings and the step of middle splined shaft retaining interference fit.
Described central siphon is provided with balancing patch.
Described slip yoke assembly is provided with oil nozzle.
The beneficial effects of the utility model are embodied in:
1, the part of the required use of drive shaft cartridge timing before and after having saved in the prior art.
2, middle clevis has replaced an intermediate flange and a flanged yoke, wherein saves a part.
3, saved the front and back used time of driving-shaft assembly assembling.
4, a dynamically balanced time has been saved in two dynamic balancing simultaneously, and efficient improves.
5, realized before and after the whole dynamic balancing of driving-shaft assembly, the phenomenon of driving-shaft assembly balance stack before and after having eliminated has been eliminated difficult and complicated cases such as the car load abnormal sound that caused by transmission shaft, resonance.

Fig. 2 is rear propeller shaft assy. structural representation in the prior art.
Fig. 3 is structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the present invention will be further described.Should be understood that following examples are only for explanation the present invention but not for limiting the scope of the invention.
Embodiment 1
Referring to Fig. 3, the utility model provides connects the V shape driving-shaft assembly in a kind of, comprises front propeller shaft assy. 1 and rear propeller shaft assy. 2, connects by middle clevis 3 assemblings between described front propeller shaft assy. 1 and the rear propeller shaft assy. 2; The front-end face of clevis 3 leans against on the intermediate support assembly internal bearings 4 of front propeller shaft assy. 1 in the middle of described, and by nut 5, packing ring 6 fixing and lockings, the rear end of clevis 3 is connected on the slip yoke assembly 7 of rear propeller shaft assy. 2 in the middle of described, and be connected with the universal-joint cross trunnion assembly 8 of rear propeller shaft assy. 2, fixing by snap ring 9.
Present embodiment and embodiment's 1 difference is: in order to guarantee the whole dynamic balancing of duplex driving-shaft assembly, can balancing patch 13 be set at central siphon 12, to reduce remaining amount of unbalance; 14 pairs of spline pairs of oil nozzle are set on the slip yoke assembly 7 to be lubricated.
