Abstract
The utility model discloses an axial rigidity-enhancing bush. The axial rigidity-enhancing bush comprises a cylindrical shell, a cylindrical core with a spherical projection at the middle is arranged in the cylindrical shell, a rubber layer which is vulcanized to be molded integrally is arranged between the cylindrical shell and the cylindrical core with the spherical projection at the middle, the middle of the inner wall of the cylindrical core with the spherical projection at the middle is provided with an annular notch, the upper and the lower ends of the rubber layer are respectively inwardly sunken to form annular grooves, and the inner walls of the annular grooves are provided with steps. The structure of the axial rigidity-enhancing bush is simple, the process is easy to operate, the axial rigidity of products can be enhanced, consequently, the service lives of products can be prolonged, and the axial shock-bearing capability of a suspension control arm is guaranteed.
Description
Technical field
The utility model relates to the control arm lining that a kind of automobile suspension system is used.
Background technique
Lining is to be used for outside the mechanical part, the auxiliary equipment that is used as supporting, damping and reverses.The using scope of lining is very wide, and a lot of parts all can use lining like parts such as valve, bearings in the industrial field.A large amount of rubber bushings etc. of adopting flexibly connect the requirement of satisfying the Vehicle damper noise reduction in the Modern Car suspension, and the precise design of suspension already needs the coupling of the various performance parameters of rubber bushing.Also utilization is very wide in automobile for lining, mainly is used in positions such as subframe, front suspension control arm, rear suspension control arm.Its not only available buffer impact of control arm rubber bushing also has the effect of spring and suspension swing arm bearing concurrently, and some rubber bushings that reversed also play the effect of universal coupling, and the flexibility of reversing and tilting is provided, and is used for axially controlling with displacement radially.
The lining of ordinary construction can not axially provide big rigidity; This product is through structural design and technology riveting to lining inner core, outer tube; Improved the axial rigidity of lining; And the locking through the outer tube external diameter, eliminated rubber because the stress that the cooling of sulfuration back is shunk, the working life of also having improved product.
The model utility content
The purpose of the utility model provides a kind of lining that increases axial rigidity, is applied to the automotive field suspension system, strengthens the axial rigidity of rotating shaft in rotation process, and is used for improving control arm in the axial ability that is hit.
The technological scheme of the utility model is following:
A kind of lining that increases axial rigidity; Include barrel-type casing; Be provided with the inner core of tubular and intermediate portion dribbling shape projection in the described barrel-type casing; The rubber layer that has the integrated vulcanizing moulding between the inner core of described barrel-type casing and tubular and intermediate portion dribbling shape projection; It is characterized in that: the middle part of the inwall of the inner core of said tubular and intermediate portion dribbling shape projection is provided with annular breach, and the upper and lower end of said rubber layer caves inward respectively and forms annular groove, and the inwall of annular groove is provided with step.
The lining of described increase axial rigidity is characterized in that: the inner core of said tubular and intermediate portion dribbling shape projection is by seamless steel pipe extrusion modling through two ends.
The lining of described increase axial rigidity; It is characterized in that: the utility model lining in mould by the inner core of cylindrical outer casing, tubular and intermediate portion dribbling shape projection, rubber sulfidization molding together; Locking and riveting cylindrical outer casing after the moulding; Make cylindrical outer casing become () shape housing, increased the axial rigidity of product.
The beneficial effect of the utility model:
The utility model is simple in structure, and the technology easy operating, has increased product in axial rigidity, has improved the life-span of product, has guaranteed that irs control arm is in the axial ability that is hit.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1; A kind of lining that increases axial rigidity includes barrel-type casing 1, is provided with the inner core 2 of tubular and intermediate portion dribbling shape projection in cylinder outer race 1 body; The rubber layer 3 that has the integrated vulcanizing moulding between the inner core 2 of barrel-type casing 1 and tubular and intermediate portion dribbling shape projection; The middle part of the inwall of the inner core of tubular and intermediate portion dribbling shape projection is provided with annular breach 4, and the upper and lower end of rubber layer 3 caves inward respectively and forms annular groove 5, and the inwall of annular groove 5 is provided with step 6.
The inner core 2 of tubular and intermediate portion dribbling shape projection is by seamless steel pipe extrusion modling through two ends, during displacement about the 10mm on lining takes place axially in the course of the work, can reach the rigidity requirement of 20-25KN; There is rotating shaft to pass tubular inner core 1 from top to bottom successively and be rotatably assorted with the inwall of the inner core 2 of tubular and intermediate portion dribbling shape projection.
Claims (3)
1. lining that increases axial rigidity; Include barrel-type casing; Be provided with the inner core of tubular and intermediate portion dribbling shape projection in the described barrel-type casing; The rubber layer that has the integrated vulcanizing moulding between the inner core of described barrel-type casing and tubular and intermediate portion dribbling shape projection; It is characterized in that: the middle part of the inwall of the inner core of said tubular and intermediate portion dribbling shape projection is provided with annular breach, and the upper and lower end of said rubber layer caves inward respectively and forms annular groove, and the inwall of annular groove is provided with step.
2. the lining of increase axial rigidity according to claim 1 is characterized in that: the inner core of said tubular and intermediate portion dribbling shape projection is by seamless steel pipe extrusion modling through two ends.
3. the lining of increase axial rigidity according to claim 1 is characterized in that: by the inner core of cylindrical outer casing, intermediate portion dribbling shape, rubber sulfidization molding together, locking and riveting become the tubular profile to said lining after the moulding in mould.
