Abstract
The utility model provides a shock attenuation car pull rod joint mechanism, includes bulb round pin and overcoat in the joint of bulb round pin afterbody, bulb round pin afterbody is the bulb, and in the bulb seat is located to the bulb, its characterized in that: bulb round pin overcoat is equipped with dustproof a pad, be equipped with a plurality of evenly distributed's mounting hole on the dustproof pad inner wall, install in the mounting hole rather than self diameter assorted spring, spring one end is exposed outside the mounting hole, the dustproof inner wall that fills up is equipped with the shock attenuation cover that link up mutually with the mounting hole, the one end that the spring exposes outside the mounting hole is contradicted on shock attenuation cover inner wall, it is umbelliform that shock attenuation cover cross -section is the descending, shock attenuation cover surface contacts with bulb round pin surface, the shock attenuation cover all is the rubber material with dustproof the pad. The utility model discloses a shockproofness minimizing that can go the automobile and produce on the road that jolts.
Description
Technical field
The utility model relates to a kind of automobile pull rod joint mechanism, particularly a kind of damping automobile pull rod joint mechanism.
Background technique
Automobile pull rod joint mechanism is the important accessory in auto steerer, extremely important effect is played in motor turning process, and automobile pull rod joint mechanism and wheel, contact between steering wheel is very tight, when automobile running to jolt location time, wheel can produce larger vibrations and fluctuating thus automobile pull rod joint mechanism is shaken, if there are vibrations in automobile pull rod joint mechanism, steering wheel can be caused also to occur vibrations, cause driving unstable, if automobile pull rod joint mechanism vibrations are too strong, driving personnel can cause excessively being by force difficult to steering wheel of holding with a firm grip due to seismaesthesia, as easy as rolling off a log initiation is unexpected, jeopardize the personal safety of driving personnel.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of damping automobile pull rod joint mechanism, and the shockproofness that automobile can be travelled generation by it on bump course minimizes.
The technical scheme in the invention for solving the above technical problem is:
The utility model discloses a kind of damping automobile pull rod joint mechanism, comprises ball stud and is coated at the joint of ball stud afterbody, and ball stud afterbody is bulb, and bulb is located in ball cup, it is characterized in that: be arranged with a dust-proof cushion outside described ball stud; Described dust-proof cushion inwall is provided with some equally distributed mounting holes; Be provided with the spring matched with himself diameter in described mounting hole, spring one end is exposed outside mounting hole; Described dust-proof cushion inwall is provided with the damping cover connected with mounting hole; Conflict on damping cover inwall in the exposed one end outside mounting hole of described spring; Described damping cover cross section is parachute-like; Described damping cover outer surface contacts with ball stud outer surface; Described damping cover and dust-proof cushion are all quality of rubber materials.
The diameter range of described mounting hole is 0.5cm to 1.5cm.
Described ball cup is quality of rubber materials.
The beneficial effects of the utility model are:
Compared with prior art, when adopting the damping automobile pull rod joint mechanism of the utility model structure to receive the shaking force produced in vehicle traveling process, ball stud can produce vibrations thereupon, because damping cover outer surface contacts with ball stud outer surface, therefore when ball stud produces shaking force, shaking force can directly pass on damping cover, because damping cover cross section is parachute-shaped, surface area is larger, shaking force can be weakened to the full extent when shaking force conducts on damping cover, and a remaining shaking force part is directly transferred on dust-proof cushion by damping cover, and dust-proof cushion and damping cover are all quality of rubber materials, therefore by the material of itself, shaking force is weakened, shaking force is weakened by the spring damping of self by the spring that another part shaking force is then conflicted on damping cover inwall by one end, the shaking force finally making ball stud be subject to is almost negligible, the steering wheel avoiding automobile produces vibrations due to automobile pull rod joint mechanism thus causes occurring the situation of vibrations, ensure that the stability of steering wheel, the personal safety of driving personnel is more made to be protected.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model damping automobile pull rod joint mechanism;
Fig. 2 is the enlarged view in Figure 1A portion.
Embodiment
Refer to Fig. 1, Fig. 2, the utility model provides a kind of damping automobile pull rod joint mechanism, and comprise ball stud 1 and be coated at the joint 2 of ball stud afterbody, ball stud 1 afterbody is bulb 3, bulb 3 is located in ball cup 4, is arranged with a dust-proof cushion 5 outside described ball stud 1; Described dust-proof cushion 5 inwall is provided with some equally distributed mounting holes 6; Be provided with the spring 7 matched with himself diameter in described mounting hole 6, spring 7 one end is exposed outside mounting hole 6; Described dust-proof cushion 5 inwall is provided with the damping cover 8 connected with mounting hole 6; Conflict on damping cover 8 inwall in the exposed one end outside mounting hole of described spring 7; Described damping cover 8 cross section is parachute-like; Described damping cover 8 outer surface contacts with ball stud 1 outer surface; Described damping cover 8 is all quality of rubber materials with dust-proof cushion 5.
When automobile travels on bump course, wheel can be trembled, the shaking force that wheel bears then can to automobile pull rod joint mechanism transmission, now, ball stud 1 can produce vibrations thereupon, because damping cover 8 outer surface contacts with ball stud 1 outer surface, therefore when ball stud 1 produces shaking force, shaking force can directly pass on damping cover 8, because damping cover 8 cross section is parachute-shaped, surface area is larger, shaking force can be weakened to the full extent when shaking force conducts on damping cover 8, and a remaining shaking force part is directly transferred on dust-proof cushion 5 by damping cover 8, and dust-proof cushion 5 and damping cover 8 are all quality of rubber materials, therefore by the material of itself, shaking force is weakened, shaking force is weakened by the spring damping of self by the spring 7 that another part shaking force is then conflicted on damping cover 8 inwall by one end, the shaking force finally making ball stud 1 be subject to is almost negligible, the steering wheel avoiding automobile produces vibrations due to automobile pull rod joint mechanism thus causes occurring the situation of vibrations, ensure that the stability of steering wheel, the personal safety of driving personnel is more made to be protected.
The diameter range of described mounting hole 6 is 0.5cm to 1.5cm; And the spring 7 matched with himself diameter is installed in mounting hole 6, therefore the diameter of spring 7 is also defined thereupon, make installed spring 7 diameter can not be excessive, avoid because the larger elastic force of the excessive generation of spring diameter causes ball stud in swing process by the situation that spring force pushes, there will not be because the pushing of spring 7 elastic force causes ball stud 1 to swing inflexible situation.
Described ball cup 4 is quality of rubber materials; Therefore, when bulb 3 rotates in ball stud 1 swing process thereupon, even if rub with ball cup 4, also there will not be the situation of wearing and tearing.
