Abstract
The invention relates to a middle supporting frame assembly which comprises upper and lower supporting frames, rubber gaskets, a middle spline shaft, a middle connecting fork and supporting frame bearings, wherein the supporting frame bearings are sleeved in the middle of the middle spline shaft, and the middle connecting fork is sleeved at the tail end of the middle spline shaft; the end surface of the middle connecting fork abuts on the end surfaces of the supporting frame bearings; two ends of the supporting frame bearings are sleeved in the rubber gaskets, and the rubber gaskets are mounted in the upper and lower supporting frames; flow guide grooves are formed in the lower parts of the rubber gaskets; the flow guide grooves, the middle connecting fork and left and right dust covers form a flow guide cavity; and the flow guide grooves and the flow guide cavity are communicated with a flow guide hole. The middle supporting frame assembly has the beneficial effects that impurities are prevented from damaging the supporting frame bearings; the impurities close to the middle spline shaft are thrown away from the supporting frames along the inclined surfaces on two sides of the rubber gaskets under the action of a high-speed rotary centrifugal force of a transmission shaft; the middle spline shaft rotates quietly and noiselessly; the supporting frames can flexibly rotate due to small starting torque; the supporting frame bearings are directly mounted in the rubber gaskets; and the enveloping range is relatively wide.
Description
Technical field
The present invention relates to the structure of drivetrain components in automobile, especially a kind of intermediate support frame assembly.
Background technique
In current existing supporting frame assembly, there are a kind of bearing support two ends without seal lip, impurity etc. easily enter in bearing support, can not discharge, with silt particle friction bearing seal ring after grease mixed-stacking in bearing support, accelerate the wearing and tearing of seal ring, reduced bearing working life, also have a kind of bearing support one end to have seal lip, bearing support seal ring is two lips, has seal lip side to be contained in transmission shaft windward side, double-lip seal poor performance, and impurity still easily enters in bearing support, also have a kind of bearing support two ends to have seal lip, bearing support seal ring changes three lips into by two lips, sealability improves, impurity etc. are difficult for entering in bearing support, but bearing support lip is the in the situation that of insufficient lubrication, easily produce the noise that rubber and axle dry wear produce, after entering foreign matter in seal lip, can not discharge, in bearing sealed ring outside, bearing sealed ring is rubbed, damage bearing, seal ring easily generates heat in the time of high-speed friction, to periphery bearing, the working life of the parts such as rubber ring, in rotary course, there is friction torque in support, add the starting torque of big drive shaft, bearing support shoulder height is low, rack shaft holder is easily deviate from from support rubber ring.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, provides that a kind of performance is better, the intermediate support frame assembly of longer service life.
The present invention solves the technological scheme that its technical problem adopts: this intermediate support frame assembly, comprise lower supporting frame, rubber washer, middle spline shaft, middle clevis and bracket bearing, middle spline shaft neutral position place is set with bracket bearing, clevis in the middle of middle spline shaft terminal position is set with; The end face of middle clevis is connected to bracket bearing end face; Two ends of bracket bearing are sleeved in rubber washer, and rubber washer is arranged in lower supporting frame, and the two side faces of bracket bearing is provided with left and right dust-proof cover; Seal lip place in rubber washer bottom near bracket bearing is provided with the guiding gutter that is ramp structure, and guiding gutter, middle clevis and left and right dust-proof cover form diversion cavity, and guiding gutter and diversion cavity are all connected with flow-guiding mouth.
The effect that the present invention is useful is: the present invention's employing is dredged foreign matter volume mode and prevented that impurity from causing damage to bracket bearing, approach the impurity of middle spline shaft under the effect of transmission shaft High Rotation Speed centrifugal force, inclined-plane along rubber washer both sides throws away support, quiet noise free when middle spline shaft rotation, the problem of temperature rise that support causes without seal ring frictional heating, the starting torque of support is little, rotate more flexible, bracket bearing is directly contained in rubber washer, envelope is wider, can not produce the problem of deviating from without bearing support from rubber washer.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present invention;
Description of reference numerals: upper lower supporting frame 1, rubber washer 2, left and right dust-proof cover 3, middle spline shaft 4, middle clevis 5, bracket supports circle 6, bracket bearing 7, guiding gutter 8, diversion cavity 9, flow-guiding mouth 10.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in the figure, this intermediate support frame assembly, comprise lower supporting frame 1, rubber washer 2, middle spline shaft 4, middle clevis 5 and bracket bearing 7, middle spline shaft 4 neutral position places are set with bracket bearing 7, clevis 5 in the middle of middle spline shaft 4 terminal positions are set with; The end face of middle clevis 5 is connected to bracket bearing 7 end faces; Two ends of bracket bearing 7 are sleeved in rubber washer 2, and rubber washer 2 is arranged in lower supporting frame 1, and the two side faces of bracket bearing 7 is provided with left and right dust-proof cover 3; Be provided with the guiding gutter 8 that is ramp structure near the seal lip place of bracket bearing 7 in rubber washer 2 bottoms, guiding gutter 8, middle clevis 5 and left and right dust-proof cover 3 form diversion cavity 9, and guiding gutter 8 and diversion cavity 9 are all connected with flow-guiding mouth 10.The design of guiding gutter 8 and diversion cavity 9 is easy to the discharge of silt particle, and bearing sealed ring outside is piled up without silt particle, and prevent that axle bed seal ring from piling up the enhance faster wear causing because of silt particle in bearing support, thereby improved bearing life, and noise free.In rubber washer 2, be provided with bracket supports circle 6, for rubber washer 2 is pressed solidly in upper lower supporting frame 1.
In addition to the implementation, the present invention can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
