Abstract
The utility model relates to an automobile tie rod ball with an adjustable ball wrist, belonging to the technical field of automobile parts. The automobile tie rod ball with an adjustable ball wrist comprises a ball cup, a tie rod ball, an upper ball wrist, a lower ball wrist, a dust cover and an end cover, wherein the tie rod ball is arranged in the ball cup through the upper ball wrist and the lower ball wrist, a spring is arranged on the bottom of the tie rod ball through an inner gasket, and the end cover is arranged on the end port of the ball cup below the spring through a pin column thread; and the dust cover is sleeved on the tie rod ball above the ball cup. The pressure of the spring to the ball wrist can be regulated through rotating the end cover, thus the coordination dynamics of the ball wrist and the tie rod ball is regulated by using the rigidity characteristic of the spring, and thus the purpose that the starting torque is in the range of (N.M) 1-3.5 is achieved. The automobile tie rod ball with the adjustable ball wrist solves the problems that the starting torque is correspondingly reduced until failure to cause that the ball drops because relative friction is generated between the traditional ball and the plastic all-wrapping lining and the coordination gap is gradually increased, and has the characteristics of simple structure and strong practicability.
Description
Technical field
The utility model relates to the adjustable automobile tie rod ball of a kind of ball wrist, belongs to technical field of automobile parts.
Background technique
The automobile tie rod ball is parts of automobile rod assembly, and 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 goes on road.
The automobile rod assembly is except that the hard connection of pull bar, and tie rod ball is carried out angle and changed connection.The automobile tie rod ball is secondary by ball seat body and bulb component movement, kinetic friction steering angle: a ≧ 40 °, and tripping force is refused (N.M) 1-3.5.
Because ball seat body and bulb component movement are secondary; Traditional mode is that bulb and ball seat liner adopt the full pack arrangement of plastics; Automotive tie-rod end is under frequent motion, and the full ladle-lining of bulb and plastics produces friction relatively, and matching gap strengthens gradually; Then corresponding the reducing of starting torque causes bulb to come off until inefficacy, and its result directly influences the working life and the replacement cycle of rod assembly.
Summary of the invention
The purpose of the utility model is: provide a kind of through regulating the pressure of ball wrist; Tripping force is declinatured be held in (N.M) 1-3.5 scope; To solve the full ladle-lining generation of existing bulb and plastics friction relatively; Matching gap strengthens gradually, and starting torque is then corresponding to be reduced to cause the come off adjustable automobile tie rod ball of ball wrist of problem of bulb until inefficacy.
The utility model is to realize above-mentioned purpose through following technological scheme:
The adjustable automobile tie rod ball of a kind of ball wrist; It is made up of ball cup, tie rod ball, last ball wrist, following ball wrist, dust-proof cover and end cap; It is characterized in that: through last ball wrist and following ball wrist tie rod ball is installed in the ball cup; The tie rod ball bottom is provided with spring through inner washer, through the pin screw thread end cap is installed on the ball cup port of spring below; Be set with dust-proof cover on the tie rod ball of ball cup top; Described going up between ball wrist and the following ball wrist is provided with filler opening, and the outer wall of ball cup one side is provided with the oil nozzle that is communicated with filler opening, and described tie rod ball top is equipped with nut through cotter pin.
The advantage of the utility model is:
The tie rod ball of the utility model is assemblied in the upper and lower ball wrist; Spring combines with following ball wrist; End cap combines with spring; Through rotating end cap is the pressure of adjustable springs to the ball wrist, and then utilizes the dynamics that cooperates of stiffness characteristics adjusting ball wrist with the tie rod ball of spring, reaches starting torque in (N.M) 1-3.5 scope with this.To avoid existing bulb and the full ladle-lining of plastics to produce friction relatively; Matching gap strengthens gradually; Starting torque is then corresponding to reduce the problem that causes bulb to come off until inefficacy, and the adjustable automobile tie rod ball of this ball wrist is simple in structure, practical; Through the screw thread installation end cover and the fixing pin of end cap, can reach convenient and regulate, maintenance and the purpose changed.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Among the figure: 1, pin, 2, end cap, 3, spring, 4, inner washer, 5, ball wrist down, 6, oil nozzle, 7, go up the ball wrist, 8, dust-proof cover, 9, tie rod ball, 10, nut, 11, cotter pin, 12, ball cup, 13, filler opening.
Embodiment
The adjustable automobile tie rod ball of this ball wrist is made up of ball cup 12, tie rod ball 9, last ball wrist 7, following ball wrist 5, dust-proof cover 8 and end cap 2; With following ball wrist 5 tie rod ball 9 is installed through last ball wrist 7 in the ball cup 12, tie rod ball 9 tops are equipped with nut 10 through cotter pin 11.Be provided with filler opening 13 between last ball wrist 7 and the following ball wrist 5, tie rod ball 9 bottoms are provided with spring 3 through inner washer 4, through pin 1 screw thread end cap 2 are installed on ball cup 12 ports of spring 3 belows; Be set with dust-proof cover 8 on the tie rod ball 9 of ball cup 12 tops; The outer wall of ball cup 12 1 sides is provided with the oil nozzle 6 that is communicated with filler opening 13.
The tie rod ball 9 of the adjustable automobile tie rod ball of this ball wrist is assemblied in ball wrist 7 and the following ball wrist 5; Spring 3 combines with following ball wrist 5; End cap 2 is connected with spring 3 contacts; Through rotating end cap 2 is the pressure of 3 pairs of following ball wrists 5 of adjustable springs, and then utilizes the dynamics that cooperates of stiffness characteristics adjusting ball wrist with the tie rod ball 9 of spring 3, reaches starting torque in (N.M) 1-3.5 scope with this.
The adjustable automobile tie rod ball of this ball wrist is owing to adopted the pressure through 3 pairs of following ball wrists 5 of end cap 2 Regulation springs; Therefore carry out auxiliary adjustment through the gap that kinetic friction produces by spring 3 between tie rod ball 9 and the ball wrist; And then avoided existing bulb and the full ladle-lining of plastics to produce friction relatively; Matching gap strengthens gradually, and then corresponding the reducing of starting torque causes bulb to come off until inefficacy, and its result directly influences the problem of the working life and the replacement cycle of rod assembly.
The adjustable automobile tie rod ball of this ball wrist is through the screw thread installation end cover 2 and the fixing pin 1 of end cap 2, can reach convenient and regulates, maintenance and the purpose changed.And have characteristics simple in structure, practical.
