Abstract
The utility model relates to a middle supporting assembly of an automobile transmission shaft. The middle supporting assembly comprises a middle supporting shell, a middle supporting sleeve ring and a middle supporting bearing; an inner concave groove is arranged in the middle supporting shell; the middle supporting sleeve ring is fixedly arranged inside the concave groove of the middle supporting shell; a bearing protection sleeve is embedded inside the middle supporting sleeve ring; and the bearing protection sleeve and the middle supporting bearing are in interference fit. According to the middle supporting assembly provided by the utility model, the service life of the middle supporting assembly can be greatly prolonged; a loading test and a road test can be passed; the economical effects are obvious; and the middle supporting assembly has a good application prospect.
Description
Technical field
The utility model relates to a kind of Vehicle Propeller Shaft Supporting Bracket assembly, belongs to propeller-shaft equipment technology field.
Background technology
In automotive field, for transferring power between two parts of certain distance is being arranged, generally need to install transmission shaft, if but the transmission shaft distance is longer, then often needs transmission shaft is divided into some sections, and by transmission shaft center support assembly supporting shaft.Traditional center support assembly following problem can occur in the automobile use procedure: (1) because jitter problem in the vehicle traveling process, center support assembly rigidity, rubber neck occur easily rubber skeleton aging tear to damage come off, retainer comes off; (2) center support bearing poor sealing enters easily silt and causes the wear-out failure of center support bearing abnormal in early stage; (3) center support insufficient rigidity causes the center support collar to destroy.
Original center support assembly directly is connected with car chassis by the midship mounting rubber skeleton, the center support bearing steel ball size is Φ 7.9375mm, the bearing inner ring width is 19mm, the outside race external diameter is Φ 75, the groove width of rubber skeleton seat both sides is 4mm, dark 11.5m, the rated load of bearing is Cr=14kN, Cor=10kN.At bearing surface two gear mud collars are housed, such structure can satisfy the demand of driving-shaft assembly substantially, but according to three parcel post situations, the fault rate of tween drive spindle is higher.Be the loading ability of bearing insufficient strength by analyzing major cause, and the intensity of rubber skeleton is less, easy aged deterioration.
The utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, proposes a kind of Vehicle Propeller Shaft Supporting Bracket assembly structure, and transmission shaft center support assembly fault rate is reduced, and improves the service life of product.
The technical scheme that the utility model solves above technical matters is: the Vehicle Propeller Shaft Supporting Bracket assembly is provided; comprise center support housing, the center support collar and center support bearing; it is characterized in that: described center support housing has the concave shaped groove; the described center support collar is fixed in the Baltimore groove of described center support housing; be embedded with bearing protecting jacket at the described center support collar, described center support bearing is assembled in interference in the described bearing protecting jacket.
The technical scheme that the utility model further limits is: aforesaid Vehicle Propeller Shaft Supporting Bracket assembly, the mounting ear bottom of described center support housing both sides is welded with the reinforced rib that is connected with described center support housing, in order to improve the intensity of center support housing.
Further, aforesaid Vehicle Propeller Shaft Supporting Bracket assembly, the described center support collar is connected by sulfuration with described bearing protecting jacket.
The beneficial effects of the utility model are: the utility model makes the rated load of bearing by original Cr=14kN, Cor=10kN by structural development, bring up to Cr=20.9kN, Cor=13.1kN, the life-span of center support assembly is greatly improved, and has passed through the road through service testing and has had a try and test.Be greatly improved the service life of this structure, and its remarkable in economical benefits has a good application prospect.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
A kind of Vehicle Propeller Shaft Supporting Bracket assembly that present embodiment provides, structure comprise center support housing 1, the center support collar 2 and center support bearing 3 as shown in Figure 1.The bearing specification that adopts is steel ball size Φ 9.525mm, and bearing outside diameter Φ 72mm, internal diameter are Φ 40mm, bearing inner ring width 22mm, rated load: Cr=20.9kN, Cor=13.1kN; Center support collar both sides are provided with groove, and groove width is 4mm, are 11.8mm deeply; The mounting ear bottom of center support housing both sides is welded with the reinforced rib 4 that is connected with the center support housing, and the midship mounting assembly is connected with car chassis by the mounting ear of midship mounting housing; Bearing sheath interference fit in center support bearing and the center support collar.
To sum up the technical scheme of said present embodiment on the basis of original midship mounting assembly structure, by the improvement of structure and specification, satisfies the actual technical requirements of using, and reduces hazard rate, has improved the service life of product and user's satisfaction.The transmission shaft midship mounting result of present embodiment shows that by vehicle road test new construction transmission shaft center support result's in-use performance is equal to original design, and, by larger raising have have a good application prospect than original design service life.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
