Abstract
The utility model provides a longitudinal traction bar buffering cushion with a novel structure and aims at overcoming shortcomings of an existing longitudinal traction bar buffering cushion. The longitudinal traction bar buffering cushion comprises a buffering cushion body and a liner tube, wherein the buffering cushion body is made of polyurethane materials. An annular groove is formed in the outer wall of the buffering cushion body, and a limiting groove is formed in the inner wall of the buffering cushion body; the cylindrical and metallic linear tube closely connected with the buffering cushion body is arranged in a through hole. The longitudinal traction bar buffering cushion has the advantages of being high in elasticity, excellent in tensile strength and tearing strength, and capable of effectively absorbing constantly-changing tension and extrusion force through the designed grooves. The longitudinal traction bar buffering cushion is capable of bearing large impact and extrusion force, excellent in impact resistance and abrasive resistance, capable of achieving good buffering and energy absorption functions, and beneficial to reducing fatal dangers of off tracking, front sway and drifting of automobiles.
Description
Technical field
The utility model relates to field of automobile, relates in particular to a kind of longitudinal rod cushion rubber of lilliput car.
Background technology
Existing two front suspensions that drive lilliput car generally comprise underneath type, not isometric lower cross arm and Top Crossbeam, and are connected with car body with Panhard rod by longitudinal rod.Wherein, longitudinal rod one end is connected with lower cross arm, and the other end of longitudinal rod is installed on the propelling rod bearing of automobile chassis frame by the longitudinal rod cushion rubber.
Automobile because the jolting of road surface, makes the Top Crossbeam of automobile and lower cross arm upper and lower beating constantly in the process of moving, beats in the reasonable scope in order to control transverse arm, need cushion adjusting by longitudinal rod; Especially under the situation of vehicle starting, acceleration and emergency brake, needs employing longitudinal rod cushion rubber cushions the instantaneous stress between front suspension and the car body especially.
But the longitudinal rod cushion rubber on the lilliput car all adopts simple circular cone structure and is the cushion rubber of rubber material at present, there is following defective in this rubber buffer: 1. elastomeric material rubber buffer mechanical strength is low, stretch-proof and extrusion capability are relatively poor, and elastomeric material oil resistant, weather resisting property is also relatively poor, easily aging, cause the service life of longitudinal rod cushion rubber shorter; 2. because rubber buffer self-deformation amount is big and conformability is relatively poor, automobile deviation phenomenon can occur in the process of moving, also can occur the fatal risk of car load yaw and whipping under the situation of emergency brake.
The utility model content
At the above-mentioned deficiency of existing longitudinal rod cushion rubber, the utility model provides a kind of longitudinal rod cushion rubber of new construction, and its concrete structure is:
The longitudinal rod cushion rubber comprises the buffering pad 1 of polyurethane material, and the top of buffering pad 1 is provided with a through hole 11, and the outer wall of buffering pad 1 is provided with annular groove 12 one, and the inwall of buffering pad 1 is provided with limited impression 13 one; In through hole 11, be provided with a bushing pipe 2 with buffering pad 1 close-connected cylindrical tube shape, metal material; The bottom surface of bushing pipe 2 is mutually concordant with the bottom surface of buffering pad 1, and the top of bushing pipe 2 vertically extends to the outside of buffering pad 1, and namely the end face of bushing pipe 2 is higher than the end face that cushions pad 1; The two ends of bushing pipe 2 are arranged with annular protrusion 21, and are chimeric mutually near annular protrusion 21 and the limited impression 13 of bushing pipe 2 bottoms.
In addition, upper and lower two end faces of bushing pipe 2 are jagged antiskid surface 22.The end face of buffering pad 1 is with respectively being provided with semicircle muscle 14 on the bottom surface.
Beneficial technical effects
The compare product of traditional circular cone barrel structure, adopt the longitudinal rod cushion rubber of structure described in the utility model to have higher elasticity, excellent tensile strength, tear strength, and this cushion rubber design is fluted, can absorb stretching and the squeese pressure that constantly changes by actv.; When automobile emergency brake, this product bears the great impact squeese pressure again simultaneously, and possesses excellent shock resistance characteristic and resistance to abrasion, can well play buffering and energy-absorbing cushioning effect, is conducive to reduce the fatal risk of automobile sideslip, yaw and whipping; In addition, because the utility model product has good isolation greasy dirt, fuel resistance, weather resisting property, also increased its aging resistance.

Fig. 2 is the front view of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 2.
Sequence number among the figure is: buffering pad 1, bushing pipe 2, through hole 11, annular groove 12, limited impression 13, semicircle muscle 14, annular protrusion 21, antiskid surface 22.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is illustrated.
Referring to Fig. 1, the longitudinal rod cushion rubber comprises buffering pad 1, the top of the buffering pad 1 of polyurethane material is provided with a through hole 11, the outer wall of buffering pad 1 is provided with annular groove 12 one, and the inwall of buffering pad 1 is provided with limited impression 13 one, sees Fig. 3 for details; In through hole 11, be provided with a bushing pipe 2 with buffering pad 1 close-connected cylindrical tube shape, metal material, see Fig. 3 for details; The bottom surface of bushing pipe 2 is mutually concordant with the bottom surface of buffering pad 1, and the top of bushing pipe 2 vertically extends to the outside of buffering pad 1, and namely the end face of bushing pipe 2 is higher than the end face that cushions pad 1, sees Fig. 2 for details; The two ends of bushing pipe 2 are arranged with annular protrusion 21, and are chimeric mutually near annular protrusion 21 and the limited impression 13 of bushing pipe 2 bottoms, see Fig. 3 for details.
In addition, upper and lower two end faces of bushing pipe 2 are jagged antiskid surface 22, see Fig. 1 and Fig. 3 for details.The end face of buffering pad 1 sees Fig. 3 for details with respectively being provided with semicircle muscle 14 on the bottom surface.
