Abstract
The utility model discloses a hanging ball head assembly for a car. The assembly comprises a bearing base, a bearing outer ring and an internal ring ball head pin which are arranged in the bearing base, wherein the bearing outer ring is formed by splicing left and right two outer rings, closed connecting through a lock ring clamped on the outer edge of the outer ring, and packing on the outer edge on an end spherical surface of the internal ring ball head pin so as to form a slide fit pair; the bottom of the bearing base is provided with a locking cover plate which is sleeved on the internal ring ball head pin and is fixedly connected with the bearing base by a bolt; and the bottom of the bearing outer ring is resisted against the locking cover plate while the top thereof is resisted against the inner wall of the bearing base. The slide fit between the left and right two-piece bearing outer ring and the internal ring ball head pin ensures that the ball head assembly can bear a bigger axial load, has a bigger swinging angle and meets the demand of the heavy-duty engineering vehicles on the ball head assembly.
Description
Technical field
The utility model relates to a kind of the steering gear, is specifically related to a kind of automobile hanging bulb assembly, is used for the connection of automotive suspension and front axle.
Background technique
Suspension is the general name of all the power transmission connection sets between vehicle frame and the vehicle bridge (or wheel), realize universal being rotationally connected by hanging bulb assembly between suspension and the front axle, therefore hanging bulb is that suspension turns to the vital part in being, is to guarantee the steadily key of safe handling of suspension and car load.
Existing bulb is formed main two types, and a kind of is to adopt integrated type ball bowl, and this bulb assembly manufacturing is simple, low cost of manufacture, and the bulb pendulum angle is big, can bear very big thrust load, but easy to wear; Another kind is split type ball bowl, ball stud is arranged at up and down in two ball bowls that separate, as the disclosed a kind of ball stud assembly of Chinese utility model patent (CN201180735Y), for solving the gap that wearing and tearing cause, generally below the ball bowl pressure spring is being installed down, the closure of ball bowl and ball stud under guaranteeing, therefore, Zu He bulb increases more preceding a kind of working life up and down, but because the ball bowl of two halves combination, half is stressed to cause the ball bowl, and second half does not stress, so just, reduced the axial bearing capacity of bulb assembly, under the working state of often bearing greater impact power, pressure spring is easily tired and lose effectiveness, thereby ball stud and ball bowl can't be closely cooperated, quicken the wearing and tearing of ball stud, can not reach split structure Design purpose.
The bulb assembly of as seen above-mentioned two kinds of structures can't take into account that bulb pendulum angle, bearing capacity are strong, the characteristics of long service life, and this just is not suitable for the use of heavy-duty machinery engineering vehicle, as the abominable mine vehicle of operating environment etc.
Summary of the invention
The utility model purpose provides a kind of automobile hanging bulb assembly, by the improvement to structure, has improved the thrust load amount, satisfies the heavy machinery engineering vehicle to the requirement heavily loaded, shock-resistant, that pendulum angle is big.
For achieving the above object, the technical solution adopted in the utility model is: a kind of automobile hanging bulb assembly, comprise bearing support, be arranged at bearing outer ring and inner ring ball stud in the bearing support, described bearing outer ring is by a left side, right two lobe outer ring amalgamations constitute, and through being arranged in closed connection of retainer on the bearing outer ring outer rim, be wrapped on the sphere outer rim of described inner ring ball stud end, both formations pair that is slidingly matched, the bottom of described bearing support is provided with a locking cover plate, and this tightening cover sleeve-board is located on the described inner ring ball stud, and fixedlys connected with described bearing support through bolt, described bearing outer ring bottom end is butted on this locking cover plate, and top end is butted on the described bearing support inwall.
In the technique scheme, described inner ring ball stud has an outer spherical surface, bearing outer ring has an inner ball surface, can adopt the joint shaft bearing structure to constitute, described bearing outer ring be about the branch body structure of two lobes, by retainer with about two lobe amalgamations on the inner ring bulb, and be locked, make the inner ring outer spherical surface on the inner ball surface of outer ring, make slide, the bearing support bottom is provided with the locking cover plate, closed bearing support chamber is for bearing outer ring provides support.Because the axial branch body structure of two lobes about bearing outer ring adopts, the locking cover plate is an axially locating between bearing outer ring and the inner ring ball stud, the retainer radial location, left and right two lobe outer rings are all stressed, can the bearing capacity of bearing not weakened in the axial direction, adopt and divide body structure, guarantee to have bigger pendulum angle, between inner ring ball stud and the bearing outer ring grease lubrication can be set, further reduce skimming wear.
In the technique scheme, bearing outer ring in the described bearing support and inner ring ball stud constitute the joint shaft bearing structure, promptly can not consider axial deformation and wearing and tearing, locate more accurate.
In the technique scheme, the below of described locking cover plate is provided with a dust-proof cover, and an end of described dust-proof cover is fixedly connected on the described bearing support by front band, and the other end and described inner ring ball stud bottom are connected and fixed through lower catch hoop.Dust-proof cover is positioned at the below of locking cover plate, and the opening that wears for the inner ring ball stud on the sealing locking cover plate prevents that dust, impurity etc. from falling in the bearing support, reduces wear, and increases the service life.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, the bearing outer ring that is arranged in the bearing support of the utility model is made of left and right two lobe amalgamations, and by the closed connection of retainer, in the inner ring ball stud is wrapped in, the formation pair that is slidingly matched, owing to be split left and right formula outer ring, two lobe producing balanced forces, with in the past up and down split-type structural compare, guaranteed that bulb assembly can bear bigger thrust load, and had big pendulum angle; Compare with overall structure in the past, effectively reduce wearing and tearing, be suitable for the big engineering machinery vehicle of load-carrying and use;
2, adopt the joint shaft bearing structure, reduce axial deformation and wear rate, locate more accurate;
3, adopt the locking cover plate to fixedly connected, bearing outer ring is positioned in the bearing support, keep being slidingly connected with the inner ring ball stud, and between bearing outer ring and inner ring ball stud, grease lubrication is set, thereby reduce wearing and tearing, increase the service life with bearing support; And locking cover plate and retainer be to the location of bearing outer ring, guarantees and the closely cooperating of inner ring ball stud that shock-resistant ability is stronger, the needs of the abominable operating environment of adaptation engineering machinery vehicle;
4, dust-proof cover is set, the opening between sealing locking cover plate and inner ring ball stud prevents that extraneous dust, impurity from falling in the bearing support, reduces wear, and increases the service life.
