Abstract
The utility model relates to an automobile drag link ball joint with soft friction lining, belonging to the technical field of automobile parts; the automobile drag link ball joint is composed of a drag link ball joint body, a soft friction lining full board, a ball joint, a dust-proofing sleeve, an end cover, an oil nozzle and an opening nut; the soft friction lining full board is arranged in the drag link ball joint body, the ball joint is arranged in the soft friction lining full board, and the end cover and the oil nozzle are arranged below the soft friction lining full board; the dust-proofing sleeve sheathed on the ball joint is arrange at the upper part of the drag link ball joint body, and the opening nut is arranged at the upper end part of the ball joint; in the utility model, the soft friction lining full board structure made of polyformaldehyde is adopted, and a hard friction pair formed by the drag link ball joint body and the ball joint is changed into a soft friction pair structure. The problems that the existing drag link ball joint adopts steel piece hard friction, the frictional factor is high, the abrasion is rapid, and the fatigue resistance life of the products is directly affected are solved; in the utility model, the frictional factor is low, the assembly precision is improved, the starting torque condition is improved, and the fatigue resistance life of the products is improved; in addition, the parts of middle frame are reduced, the structure is simple and the manufacturing cost is low.
Description
Technical field:
The utility model relates to a kind of automobile tie rod ball with soft friction lining, belongs to the auto parts machinery technical field.
Background technique:
The automobile rod assembly is one group of parts on the automobile chassis, is made up of drag link sub-assembly, Drag link sub-assembly and upper and lower suspension bulb etc.Each sub-assembly all with the tie rod ball combine and assemble, major function is to transmit, carry out yaw maneuver power to turn to the orientation angle to front wheel to change, thereby reaches the purpose that automobile correctly travels on road.
The automobile tie rod ball is a core component of automobile rod assembly, by ball-joint body and bulb component movement pair, and kinetic friction steering angle: a 〉=40 °.Friction pair material is hardened steel I and hardened steel II, friction factor: 0.35-0.40.Because this friction pair belongs to quench steel spare hard friction, friction factor is big, and quick abrasion directly influences endurance working life of product.
Because the ball-joint body contacts with the bulb circumferential upper part, and middle frame contacts with the bulb bottom and constitutes the kinematic pair structure, work effective surface of contact and rubbing surface are 70% of spheroid circumference in addition.Again owing to due to the machining accuracy, have nonuniformity and line contact condition, it is not enough to be easy to generate the product assembly precision simultaneously, and soften is not enough when causing motion, and starting torque increases, and directly influences the usability of product.
Summary of the invention:
The purpose of this utility model is, provide the soft friction lining of a kind of employing full pack arrangement, do not contact with the bulb bottom and constitute kinematic pair by middle frame, optimize the kinematic pair structure, improve assembly precision, improve the starting torque condition, improve the automobile tie rod ball with soft friction lining of product abrasion resistance properties.
The utility model is to realize above-mentioned purpose by following technical solution:
A kind of automobile tie rod ball with soft friction lining, bag, bulb, dirt-proof boot, end cap, oil nozzle and opening nut constitute entirely by tie rod ball body, soft friction lining for it, it is characterized in that: soft friction lining is housed in the tie rod ball body wraps entirely, in the full bag of soft friction lining bulb is housed, soft friction lining wraps the below full the end cap that wraps by tie rod ball body port turnup is housed, and oil nozzle is housed on the end cap; The outer surface on tie rod ball body top is equipped with the dirt-proof boot that is sleeved on the bulb, and the opening nut is equipped with in the bulb upper end portion.C type ring is equipped with on described tie rod ball body top, and beam ring is equipped with in described dirt-proof boot bottom.
The utility model beneficial effect compared with prior art is:
This automobile tie rod ball with soft friction lining adopts the full pack arrangement of soft friction lining, with tie rod ball body and the hardened steel I of bulb composition and the friction pair of hardened steel II, changes into the soft friction pair structure that bulb and engineering plastics constitute; Compare with the structure of existing automobile tie rod ball, friction factor is reduced, assembly precision improves, and the starting torque improvement of terms improves the product endurance life-span.And do not contact the formation kinematic pair with the bulb bottom by middle frame, and cut intrinsic middle frame part, optimize the kinematic pair structure, simple in structure, low cost of manufacture.
Description of drawings:
Accompanying drawing is a kind of structural representation of the automobile tie rod ball with soft friction lining.
Among the figure: 1, tie rod ball body, 2, soft friction lining wraps entirely, 3, bulb, 4, dirt-proof boot, 5, end cap, 6, oil nozzle, 7, the opening nut, 8, C type ring, 9, beam ring.
Embodiment:
This automobile tie rod ball with soft friction lining is made of tie rod ball body 1, the full bag 2 of soft friction lining, bulb 3, dirt-proof boot 4, end cap 5, oil nozzle 6 and opening nut 7.The full bag 2 of soft friction lining is housed in the tie rod ball body 1, in the full bag 2 of soft friction lining bulb 3 is housed, the end cap 5 that the port turnup by tie rod ball body 1 wraps is equipped with in the below of the full bag 2 of soft friction lining, and oil nozzle 6 is housed on the end cap 5; The outer surface on tie rod ball body 1 top is equipped with a dirt-proof boot 4 that is sleeved on the bulb 3, and beam ring 9 is equipped with in the bottom of dirt-proof boot 4.C type ring 8 is equipped with on the top of tie rod ball body 1, and opening nut 7 (referring to accompanying drawing) is equipped with in bulb 3 upper end portions.
These kinematic pair parts with the automobile tie rod ball of soft friction lining are made of full bag 2 of friction lining and bulb 3, the full bag 2 of soft friction lining adopts polyoxymethylene to make, make and contain soft rubbing contact between the surface of contact, the containing surface of contact and the friction pair condition of existing automobile tie rod ball have thoroughly been improved, improve assistant starting moment, improved the abrasion resistance properties and the fatigue life of automobile tie rod ball product.
