Abstract

The utility model discloses an intermediate supporting structure of a transmission shaft for a two-wheel-drive vehicle. The intermediate supporting structure comprises a bearing, a bearing block and a dust cover, wherein the bearing block is a rubber ring; metal outer retaining rings are respectively adhered to two edges of an outer ring surface of the rubber ring; a metal ring bearing block framework is adhered to an inner ring surface of the rubber ring; the edge of one side of the metal ring bearing block framework is inwards folded into a ring to form a vertical side; the edge of the vertical side outwards extends along the radial direction to form a radial arc edge; the edge of the other side of the metal ring bearing block framework is fixedly connected with a metal ring dust cover framework; the shape of the section of the metal ring dust cover framework corresponds to that of the radial arc edge; the bearing is embedded between the metal ring bearing block framework and the metal ring dust cover framework; and the dust cover is clamped on the metal ring bearing block framework and the metal ring dust cover framework. The intermediate supporting structure has the advantage that the purposes of increasing stability and reducing noise are achieved.

Description

Two drive uses the transmission shaft intermediate support structure

Technical field

The utility model relates to two and drives to use transmission shaft, especially relates to two and drives to use the transmission shaft intermediate support structure.

Background technology

On the long wheelbase automobile, for improving transmission shaft critical speed, reduce true joint angle, improve the transmission system bending stiffness, improve the transmission system curved characteristic, reducing noise, often with transmission shaft segment design, layout.Center support is the critical component of transmission shaft, and is unreasonable like project organization, in use, is easy to occur transmission shaft and beats acutely, causes the wearing and tearing too early of cross joint, loses efficacy.

Summary of the invention

The utility model purpose is to provide a kind of rational in infrastructure, stable performance and the very little transmission shaft intermediate support structure of noise.

For realizing above-mentioned purpose, the utility model is taked following technical proposals:

The utility model described two drives to use the transmission shaft intermediate support structure, comprises bearing, bearing seat, dust boot, and said bearing seat is a rubber ring, and the circle wall of said rubber ring is a cavity structure, in said cavity, is bonded with the latex seal ring; Be bonded with respectively in the outer ring surface two edges of rubber ring and keep circle outside the metal; Inner ring surface at rubber ring is bonded with wire loop bearing seat skeleton; One lateral edges of said wire loop bearing seat skeleton folding in circle has a stile, the edge of said stile to extend radially outward formation radial arc edge; Be fixed with wire loop dust boot skeleton at the opposite side edge of wire loop bearing seat skeleton, the cross sectional shape of said wire loop dust boot skeleton is corresponding with said radial arc edge shape and be symmetrical in the setting of bearing seat longitudinal centerline; Said bearing is embedded between wire loop bearing seat skeleton and the wire loop dust boot skeleton, and said dust boot is installed on wire loop bearing seat skeleton and the wire loop dust boot skeleton.

Said bearing is a deep groove ball bearing.

The utility model advantage is that said bearing seat is set to the rubber ring structure, and is bonded with wire loop bearing seat skeleton at the bearing seat inner ring surface of rubber ring structure, and said bearing is embedded between wire loop bearing seat skeleton and the wire loop dust boot skeleton.Therefore, when rubber axis bearing fixedly the time, a certain amount of displacement can in axial direction take place in wire loop bearing seat skeleton and bearing, with this end float misalignment that remedies transmission shaft, reaches and improves stability, reduces the noise purpose.

Fig. 1 be the utility model partly cut open structural representation.

The specific embodiment

As shown in Figure 1; The utility model described two drives to use the transmission shaft intermediate support structure, comprises deep groove ball bearing 1, bearing seat, dust boot 2, and said bearing seat is rubber ring 3 structures; The circle wall of said rubber ring 3 is cavity 4 structures, in said cavity 4, is bonded with latex seal ring 5; Be bonded with respectively in the outer ring surface two edges of rubber ring 3 and keep enclosing 6,7 outside the metal; Inner ring surface at rubber ring 3 is bonded with wire loop bearing seat skeleton 8; One lateral edges of said wire loop bearing seat skeleton 8 folding in circle has a stile, the edge of said stile to extend radially outward formation radial arc edge 9; Be fixed with wire loop dust boot skeleton 10 at the opposite side edge of wire loop bearing seat skeleton 8, the cross sectional shape of said wire loop dust boot skeleton 10 is corresponding with said radial arc edge 9 shapes and be symmetrical in bearing seat longitudinal centerline 11 setting; Said deep groove ball bearing 1 is embedded between wire loop bearing seat skeleton 8 and the wire loop dust boot skeleton 10, and said dust boot 2 is installed on wire loop bearing seat skeleton 8 and the wire loop dust boot skeleton 10.
