A steering mechanism according to an embodiment of the present invention is described first.
The steering mechanism according to the embodiment of the present invention comprises a tie rod ball pin 1, a steering plumbing arm 2 and a tie rod (not shown in the figure). The steering plumbing arm 2 is configured with a mounting hole 21, the mounting portion 200 is penetrated through the mounting hole 21, and the locking portion 300 fixes the drawbar ball pin 1 to the steering plumbing arm 2 by penetrating the lock nut 310. The ball pin is hinged to the pull rod. The tie rod ball pin 1 is fixed with the steering plumbing arm 2.
A drawbar ball pin 1 according to an embodiment of the present invention is described below with reference to the drawings.
As shown in fig. 1 and 2, a drawbar ball pin 1 according to an embodiment of the present invention includes a ball hinge part 100, a mounting part 200, and a locking part 300.
The outer circumferential surface portion of the ball hinge 100 is configured as a spherical surface, and the ball hinge 100 is adapted to be hinged to the drawbar. The mounting portion 200 is connected to the ball hinge portion 100, the mounting portion 200 is configured with a tapered portion 210 having a tapered outer peripheral surface, the tapered portion 210 is configured with a spline 211, the mounting portion 200 is adapted to be inserted into the mounting hole 21 of the steering hanger arm 2, the spline 211 abuts against the inner peripheral surface of the mounting hole 21, and the tapered portion 210 is circumferentially fixed to the mounting hole 21 of the steering hanger arm 2 by the spline 211. A locking portion 300 is attached to the mounting portion 200 at an end thereof remote from the ball hinge 100, the locking portion 300 being adapted to be threadedly engaged with a lock nut 310 to secure the draw rod ball pin 1 to the pitman arm 2.
For example, the outer circumferential surface of the locking portion 300 is configured with an external thread adapted to be threadedly coupled with the locking nut 310. The mounting hole 21 of the steering plumbing arm 2 is a taper hole, the tie rod ball pin 1 is matched with the mounting hole 21 through the taper part 210 and is fastened through the lock nut 310, so that the tie rod ball pin 1 and the steering plumbing arm 2 are kept mounted, and the tie rod ball pin 1 is prevented from being separated from the steering plumbing arm 2.
According to the utility model discloses pull rod ball round pin 1 is constructed toper portion 210 and toper portion 210 through installation department 200 and is constructed spline 211, and installation department 200 is when installing in mounting hole 21, and spline 211 on the toper portion 200 can form the cooperation with the inner peripheral surface of mounting hole 21, and spline 211 can restrict to turn to the rotation of the mounting hole 21 of hanging down arm 2 relatively along circumference, makes lock nut 310's tightening torque fully guaranteed, promotes the security performance of whole car. Specifically, the tapered portion 210 is located at the middle of the drawbar ball pin 1 in the longitudinal direction, and the spline 211 is formed on the outer peripheral surface of the tapered portion 210. After the mounting portion 200 is inserted into the mounting hole 21, the locking portion 300 and the ball hinge portion 100 are located on both sides in the axial direction of the mounting hole 21 of the steering hanger arm 2. Through the cooperation locking of lock nut 310 and locking portion 300 one end, make installation department 200 and mounting hole 21 closely laminate, utilize the spline 211 of toper portion 210 structure, can exert frictional force to the inner peripheral surface of mounting hole 21, prevent that installation department 200 and mounting hole 21 from taking place to rotate, and then avoid lock nut 310 and locking portion 300 pine to take off.
Therefore, according to the utility model discloses pull rod ball round pin 1 has advantages such as the assembly is firm, structural strength is high, the security performance is good.
Further, the spline 211 is adapted to have an interference fit with the mounting hole 21. Wherein, mounting hole 21 is the bell mouth with installation department 200 complex, and when lock nut 310 fastened locking portion 300, messenger's installation department 200 had the operation trend to the less direction of self diameter to spline 211 forms interference fit with mounting hole 21, guarantees the moment of pull rod ball round pin 1 with lock nut 310, promotes the fastness of pull rod ball round pin 1 with the plumbing arm 21 installation.
In some embodiments of the present invention, as shown in fig. 1, the cross-sectional area of the tapered portion 210 is gradually reduced from the ball joint portion 100 to the locking portion 300.
Through the pull rod ball round pin 1 through locating mounting hole 21, ball pivot joint portion 100 is located the one end of mounting hole 21, locking portion 300 is located the other end of mounting hole 21, lock nut 310 fastens locking portion 300, apply certain pressure through the inner peripheral surface of toper portion 210 through spline 211 with mounting hole 21, thereby produce bigger frictional force, guarantee the locking moment of pull rod ball round pin 1 with lock nut 310, promote the fastness of pull rod ball round pin 1 with the perpendicular arm 21 installation that turns to.
In some embodiments of the present invention, as shown in fig. 1, the side of the mounting portion 200 facing the ball hinge 100 is configured with a first transition section 220, and the first transition section 220 is connected with the ball hinge 100 in a smooth transition.
The installation part 200 can form a distance between the part of the installation part 200 where the steering plumbing arm 2 is installed and the ball hinge part 100 by constructing the first transition section 220, and when the ball hinge part 100 is hinged with a pull rod, the pull rod is prevented from being too close to the steering plumbing arm 2 in the rotating process, so that interference is avoided.
Further, as shown in fig. 1, the cross-sectional area of the junction of mounting portion 200 and first transition section 220 is greater than the cross-sectional area of first transition section 220. The diameter of the mounting part 200 toward the ball hinge 100 is small, and the movement space of the pull rod when the pull rod is hinged to the ball hinge 100 is large, thereby improving the flexibility of the pull rod movement.
In some embodiments of the present invention, as shown in fig. 1, the spline 211 extends a length greater than the axial length of the mounting hole 21.
When mounting portion 200 is inserted into mounting hole 21, one end of tapered portion 210 has a larger diameter, and the other end of tapered portion 210 has a smaller diameter. After the end of the tapered portion 210 having a smaller diameter passes through the mounting hole 21, the end of the tapered portion 210 having a larger diameter has a diameter larger than the maximum diameter of the mounting hole. The part of the spline 211 at the end with the larger diameter of the tapered part 210 is outside the mounting hole 21, and when the locking nut 310 is locked with the locking part 300, the extending length of the spline 211 is longer than the length of the mounting hole 21, so that the axial contact area between the spline 211 and the inner circumferential surface of the mounting hole 21 is larger, and the spline 211 and the mounting hole 21 are further prevented from rotating.
In some embodiments of the present invention, as shown in fig. 1, the end of the mounting portion 200 facing the locking portion 300 is configured with a second transition section 230, and the second transition section 230 is connected with the locking portion 300 in a smooth transition manner.
