Abstract
The utility model relates to an intermediate support hanging bracket of a truck drive shaft, which comprises a housing of the intermediate support, a bearing, a bearing dust cover and a rubber sleeve, wherein the bearing dust cover is clamped on the outer ring of the bearing, the rubber sleeve is in the structure of an air bag with supporting buffer space, the inner round part of the rubber sleeve is matched and connected with the bearing dust cover, and the outer round part of the rubber sleeve is matched and connected with the housing of the intermediate support. The formed intermediate support hanging bracket of a drive shaft uses the air bag type rubber sleeve as support, the buffer space of the drive shaft and the intermediate support is enlarged, and the problem of big noise caused by the shaking of the truck body brought by the shaking of the drive shaft is solved. The utility model has the advantages of simple structure, easy fabrication, convenient installation, reliable operation, etc.
Description
(1) technical field
The utility model relates to automobile component, particularly relates to transmission shaft center support suspension bracket.
(2) background technology
In the existing automotive technology, transmission shaft center support weak point is: the supporting cushion rubber lacks necessary damping, buffering effect, that is to say that center support does not leave sufficient cushion space to transmission shaft, make the center support tension, therefore, whipping of the propelling shaft causes vehicle body not steady in the driving process, and noise is big.In addition as the rubber ring of supporting not oil resistant, easily aging, heat-resisting, ozone resistance is poor, and is damaged in the expection, is not durable, and can cause seize to damage the supporting suspension bracket when serious.
(3) summary of the invention
The technical problems to be solved in the utility model provides a kind of have damping, good buffer effect, low noise, durable transmission shaft center support suspension bracket.
The technical scheme that adopts is:
Transmission shaft center support suspension bracket comprises center support shell, bearing, bearing dust boot, rubber coating.The bearing dust boot is installed on the outside race.The center support shell is made up of last shell captive joint lower casing, and its periphery is provided with a plurality of air extractor vents.Rubber coating is to have the air sac type structure that supports cushion space, and described rubber coating is provided with a plurality of louvres, and its inner circular part and bearing dust boot are connected, and the cylindrical portion and the center support shell of rubber coating are connected, and constitutes transmission shaft center support suspension bracket.
Above-mentioned last shell and lower casing inwall are equipped with two semi-circular grooves troughed belts, the cylindrical portion assembling of semi-circular grooves troughed belt and rubber coating.
The cylindrical portion assembling junction of above-mentioned semi-circular grooves and rubber coating is equiped with tight loop.
Above-mentioned rubber coating inner circular part is provided with the bearing fixing groove, is connected with bearing dust boot assembling on being contained in bearing with the bearing positioning groove.
Above-mentioned rubber coating is provided with louvre, louvre and last shell and set corresponding the communicating of air extractor vent of lower casing.
Above-mentioned center support shell both ends respectively set firmly a nut.
The utility model adopts the supporting of air sac rubber coating, strengthened the cushion space of transmission shaft and center support, had damping, buffer action, vehicle body operates steadily, noise is little, rubber pneumatic bag itself have ageing-resistantly, wear-resisting, anti-draw, high-low temperature resistant, anti-ozone and chemical substance corrosion beharvior.Simple in structure, make easily, easy for installation.
