Abstract
The utility model discloses a precisely-cast integral rear axle housing for a low-floor vehicle. The precisely-cast integral rear axle housing comprises a descending flat-straight axle housing and a rear axle housing body located on the same straight line with a semi-axle, wherein the descending flat-straight axle housing is connected with the rear axle housing body through an oblique axle housing, the left end of the descending flat-straight axle housing is provided with a main speed-reducing assembly installing bulge housing, and flange plates are arranged at two ends of the rear axle housing body. The precisely-cast integral rear axle housing is characterized in that the descending flat-straight axle housing, the rear axle housing body, the oblique axle housing, the main speed-reducing assembly installing bulge housing and the flange plates arranged at the rear axle housing body mouth portions at two ends are precisely cast to form a whole. Due to the fact that the descending flat-straight axle housing, the rear axle housing body, the oblique axle housing, the main speed-reducing assembly installing bulge housing and the flange plates arranged at the rear axle housing body mouth portions at two ends are precisely cast to form a whole, the strength of the rear axle housing for the low-floor vehicle can be improved, the production cost can be reduced, the precision can be high, the service life can be prolonged, and meanwhile the labor efficiency is also improved.
Description
Technical field
The utility model relates to the improvement of a kind of low floor vehicle with rear-axle casing, specifically precision cast integral type rear-axle casing for a kind of low floor vehicle.
Background technology
At present, the rear-axle casing that low floor vehicle is used, there is the rear-axle casing of straight axle housing in the middle of being, be provided with the bulge shell of the main deceleration assembly of installation at the left end of the straight axle housing in the whereabouts of rear-axle casing, and the diapire of the diapire of bulge shell and the straight axle housing that falls is in a plane; Left port at rear-axle casing is provided with the two-stage reduction gear mounting flange, right output port at rear-axle casing is provided with the flange be connected with the right axle shaft gear case, the straight axle housing that falls is the major semiaxis mounting pipe, the rear-axle casing at straight axle housing and two ends of falling is welded and fixed by inclined tube, the low floor vehicle of this welding fabrication is by the existing deficiency of rear-axle casing: the one, and low, the easy fracture of intensity, particularly weld, more easily rupture, and affects service life; The 2nd, technique is loaded down with trivial details, efficiency is low, cost of manufacture is high; The 3rd, the making precision is low.Known by retrieving, have not yet to see the disposable report that is cast into one of rear-axle casing that will there is straight axle housing by precision casting process.
Summary of the invention
The purpose of this utility model is to provide a kind of can improve intensity and efficiency, reduce production costs, will have the disposable precision cast integral type rear-axle casing for low floor vehicle that is cast into one of rear-axle casing of straight axle housing by precision casting process.
In order to reach above purpose, the technical scheme that the utility model adopts is: precision cast integral type rear-axle casing for this low floor vehicle, comprise fall straight axle housing and with semiaxis rear-axle casing point-blank, the straight axle housing that falls is connected with rear-axle casing by the skew bridge shell, left end at the straight axle housing that falls is provided with main deceleration assembly installation bulge shell, the two ends of rear-axle casing are equipped with flange, it is characterized in that: the straight axle housing in described whereabouts, rear-axle casing, the skew bridge shell, the flange that main deceleration assembly is installed bulge shell and two ends rear-axle casing oral area is that precision cast is an integral body.
The utility model is also implemented by following measure: the oval installing port of the left end of the straight axle housing in described whereabouts for being connected with left back axle housing, and corresponding, the flange on oval installing port is also oval; Right-hand member at the straight axle housing that falls is provided with installing port; The oral area that described main deceleration assembly is installed the bulge shell is provided with the assembling flange that is cast into one.
The beneficial effects of the utility model are: the flange that bulge shell and two ends rear-axle casing oral area are installed due to the straight axle housing in described whereabouts, rear-axle casing, skew bridge shell, main deceleration assembly is that precision cast is integrated, so can improve the low floor vehicle rear-axle casing intensity, reduce production costs, precision is high, increase the service life, simultaneously, also improved efficiency.
The accompanying drawing explanation
Fig. 1 is structure front-view schematic diagram of the present utility model.
In figure: 1, the straight axle housing that falls; 2, rear-axle casing; 3, skew bridge shell; 4, main deceleration assembly is installed the bulge shell; 5, flange; 6, installing port; 7, assembling flange.
The specific embodiment
Make the utility model with reference to Fig. 1.Precision cast integral type rear-axle casing for this low floor vehicle, comprise fall straight axle housing 1 and with semiaxis rear-axle casing 2 point-blank, the straight axle housing 1 that falls is connected with rear-axle casing 2 by skew bridge shell 3, left end at the straight axle housing 1 that falls is provided with main deceleration assembly installation bulge shell 4, the two ends of rear-axle casing 2 are equipped with flange 5, it is characterized in that: the flange 5 that described whereabouts is straight axle housing 1, rear-axle casing 2, skew bridge shell 3, main deceleration assembly are installed bulge shell 4 and two ends rear-axle casing 2 oral areas is an integral body for precision cast.
As improvement of the present utility model: the oval installing port of left end for being connected with left back axle housing 2 of described whereabouts is straight axle housing 1, corresponding, the flange 5 on oval installing port be also ellipse; Right-hand member at the straight axle housing 1 that falls is provided with installing port 6, and at the interior installation major semiaxis of straight axle housing 1 that falls, the inner at the interior installation right axle shaft of rear-axle casing 2 of right-hand member, be connected the inner of major semiaxis and right axle shaft by installing port 6 by transmission gear; The oral area that described main deceleration assembly is installed bulge shell 4 is provided with the assembling flange 7 that is cast into one.
