The heavy truck driving axle input flange comprises a flange end face and an inner spline hole, the flange end face is connected with a transmission shaft, the inner spline hole is connected with a driving axle, two opposite key grooves are formed in the flange end face, bolt connecting holes are formed in two sides of each key groove, the number of the bolt connecting holes is four, a connecting flange is arranged in the rear of the flange end face and on the outer wall of the input flange, and ten through holes are formed in the circumferential direction of the connecting flange and connected with the parking brake disc. Preferably, female ends are formed on the periphery of the flange end face, and male ends are formed in the outer wall between the connecting flange and the input flange.
Description
Technical field
The utility model relates to a kind of improvement of automobile drive axle flange connector structure, particularly a kind of driving axle of heavy automobile input flange.
Background technique
At present, heavy-duty car, especially heavy truck and special purpose vehicle ransaxle input flange are that it adopts plane seam flange and flange of end face tooth mostly for connecting the critical component between ransaxle and live axle.Plane seam flange assembly structure is simple, but transmitting torque is less, and end face tooth structure flange transmitting torque is large, complicated structure, level of processing requires high, and plane seam flange assembly and propeller shaft couplings want complicated with respect to the flange assembly of end face tooth structure, and installation efficiency is not high.And these two kinds of flanges cannot directly be installed parking braking dish, need extra centre part to install, waste time and energy.
Model utility content
For deficiency of the prior art, it is a kind of easy to connect that the utility model provides, reliable in structure and can with the direct-connected driving axle of heavy automobile input flange of parking braking dish.
In order to address the above problem, this kind of driving axle of heavy automobile input flange, comprise end face of flange for being connected with transmission shaft and inner splined hole for being connected with ransaxle, described end face of flange is provided with two keyways that position is relative, and every keyway both sides are equipped with bolt connecting hole; On the rear of end face of flange and the outer wall at this input flange, be provided with a circle adpting flange, the week of this adpting flange is upwards provided with a ring through hole, for being connected with parking braking dish.
Preferably, at the outer inner stopper that is arranged with of described end face of flange; Between described adpting flange and the outer wall of this input flange, be provided with outer stopper.The quantity of described bolt connecting hole is four; The quantity of described through hole is ten.
The beneficial effects of the utility model are: this ransaxle input flange transmission adopts keyway cooperating structure, employing inner stopper location, by four hexagon head bolts and propeller shaft couplings, its stabilized structure is reliable, good manufacturability, and can directly be connected with parking braking dish by the flange arrangement on outer wall, greatly improve its versatility.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
In conjunction with Fig. 1 to Fig. 3, this kind of driving axle of heavy automobile input flange, for being connected between heavy truck or special purpose vehicle ransaxle and transmission shaft.It comprises end face of flange 1 for being connected with transmission shaft and inner splined hole 2 for being connected with ransaxle, this end face of flange is provided with two keyways 11 that position is relative, every keyway both sides are equipped with a bolt connecting hole 1a, and four attachment holes altogether, for connecting hexagon head bolt.On the rear of end face of flange 1 and the outer wall at this input flange, be provided with a circle adpting flange 13, in the week of this adpting flange, be upwards evenly provided with a ring through hole 13a, for being connected with parking braking dish.Peripheral and be provided with inner stopper 12 relative to each attachment hole at described end face of flange 1, for locating transmission axle, is provided with outer stopper 14 between adpting flange 13 and the outer wall of this input flange, for locating parking braking dish.The quantity of this bolt connecting hole 1a is four, and the quantity of this through hole 13a is ten.
As shown in Figure 4, during assembling, first adopt inner stopper location, by four each and every one hexagon head bolts, be connected with transmission shaft.Then adopt the outer stopper location between flange outer wall and adpting flange, by ten hexagon head bolts, be connected with parking braking dish 3.
It should be noted that; embodiment is only to the explanation of technical solutions of the utility model and explanation; should not be understood as the restriction to technical solutions of the utility model; any employing the technical solution of the utility model and only do local change, must fall in protection domain of the present utility model.
