The method is characterized in that: the movable end universal joint comprises a shell (31), a connecting disc (32) is arranged on the shell, a through hole (321) for a fastener to pass through is formed in the connecting disc, and a transmission tooth part (4) meshed with the end face teeth of the output flange of the gearbox is further arranged on the outer end face of the connecting disc. The utility model provides a big moment of torsion drive shaft is connected to flange formula terminal surface tooth, through driving gear transmission moment of torsion, has reduced the load of bolt, is difficult for the twist-off, increases life.

Description

Flange type end face tooth connection large-torque driving shaft

Technical Field

The utility model relates to an automobile parts field, concretely relates to big moment of torsion drive shaft is connected to flange formula end face tooth.

Background

The driving shaft assembly of the constant velocity universal joint of the automobile is an important part of the automobile, the driving shaft assembly of the constant velocity universal joint of the automobile comprises a universal joint of which one end is connected with a power output end of an automobile gearbox, and the other end is connected with a universal joint of a power input part of an automobile wheel, at present, a movable joint VL type universal joint and a flange type universal joint are generally connected with a gearbox flange through six bolts, the bolts have positioning connection function, meanwhile, torque is mainly transmitted by the aid of bolts, when a driving shaft requires large torque, radial shear force borne by the bolts is correspondingly increased, a failure mode of bolt fracture is prone to occurring, and the structure is particularly used on electric new energy vehicles, because the instantaneous torque is larger when the electric new energy automobile starts and backs, the impact resistance to be born by the bolt is increased and is more frequent, and the risk of the bolt failure is higher.

SUMMERY OF THE UTILITY MODEL

In order to overcome the not enough of background art, the utility model provides a big moment of torsion drive shaft is connected to flange formula end face tooth, it is great mainly to solve present universal joint assembly fit clearance, carries unstable problem.

The utility model adopts the technical proposal that:

big moment of torsion drive shaft is connected to flange formula end face tooth, including the jackshaft, jackshaft one end is equipped with the stiff end universal joint, the jackshaft other end is equipped with removes the end universal joint, it includes the casing to remove the end universal joint, be equipped with the connection pad on the casing, be equipped with the through-hole that is used for the fastener to pass on the connection pad, the outer terminal surface of connection pad still is equipped with and is used for the transmission tooth portion with gearbox output flange end face tooth engaged with.

The number of the through holes is four.

The drive teeth include first and second drive tooth portions that are partially interleaved.

The through hole is arranged in the transmission tooth part.

Still include the dust cover, dust cover one end through first clamp with intermediate shaft is connected, the dust cover other end through the second clamp with the casing is connected.

The inner wall of the dust cover is provided with a boss, the boss is provided with a latch, the outer wall of the shell is provided with a connecting groove, a clamping groove is arranged in the connecting groove, the boss is arranged in the connecting groove, and the latch is matched with the clamping groove in a clamping mode.

The second clamp and the latch set up relatively.

The beneficial effects of the utility model are that: the utility model provides a big moment of torsion drive shaft is connected to flange formula end face tooth, through driving gear transmission moment of torsion, has reduced the load of bolt, and difficult twist-off increases life.

Fig. 2 is a schematic view of fig. 1 in the direction F.

Fig. 3 is an enlarged schematic view of a point a in fig. 1.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings: as shown in the figure, big moment of torsion drive shaft is connected to flange formula terminal surface tooth, including jackshaft 1, jackshaft one end is equipped with stiff end universal joint 2, the jackshaft other end is equipped with removes end universal joint 3, it includes casing 31 to remove the end universal joint, be equipped with connection pad 32 on the casing, be equipped with the through-hole 321 that is used for the fastener to pass on the connection pad, the outer terminal surface of connection pad still is equipped with and is used for the transmission tooth portion 4 with gearbox output flange terminal surface tooth engaged with. The utility model provides a big moment of torsion drive shaft is connected to flange formula end face tooth, through driving gear transmission moment of torsion, has reduced the load of bolt, and difficult twist-off increases life. The end face of the output flange of the gearbox is provided with the teeth meshed with the connecting disc, the transmission tooth part can be used for transmitting torque, the load of a bolt is reduced, the bolt is not easy to twist off, and the service life is prolonged.

In the present invention, as shown in the figure, the through holes are provided with four. The installation is more firm.

In the present invention, as shown in the figure, the transmission teeth include a first transmission tooth portion 41 and a second transmission tooth portion 42, and the first transmission tooth and the second transmission tooth are partially staggered. The transmission is more stable.

In the present invention, as shown in the figure, the through hole is provided in the transmission tooth portion. The transmission teeth protrude out of the surface of the transmission disc, and have larger contact area.

The utility model discloses in, as shown in the figure, still include dust cover 6, dust cover one end through first clamp 51 with the intermediate shaft is connected, the dust cover other end through second clamp 52 with the casing is connected.

The utility model discloses in, as shown in the figure, the dust cover inner wall is equipped with boss 53, be equipped with latch 531 on the boss, the casing outer wall is equipped with spread groove 311, be equipped with draw-in groove 312 in the spread groove, the boss is located in the spread groove, the latch with the cooperation of draw-in groove joint. The installation is more firm.

In the present invention, as shown in the figure, the second clamp and the latch are arranged relatively. That is to say the second clamp is located directly outside the latch.

The embodiments described with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention. The examples should not be construed as limiting the present invention, but any modifications made based on the spirit of the present invention should be within the scope of the present invention.
