Abstract
The utility model discloses a steering inner pull rod assembly, including casing, ball seat, ball round pin, the ball seat includes ball seat down and the last ball seat that is equipped with the inner chamber, ball round pin one end is connected in the inner chamber with last ball seat, lower ball seat links to each other with last ball seat, and lower ball seat is thermoplastic elastomer. The utility model provides a can reduce ball seat wearing and tearing, the clearance can not appear in the assembly when ball seat wearing and tearing, uses the travelling comfort good, long service life's steering inner pull rod assembly.
Description
Technical Field
The utility model relates to a steering inner pull rod assembly belongs to car coupling technical field.
Background
The steering inner pull rod assembly is an indispensable important part of an automobile, and generally comprises a ball pin, a ball seat, a shell and the like, wherein only one ball seat is formed by plastic through integral injection molding, and the steering inner pull rod assembly has the defects that the ball pin and the ball seat are large in abrasion, and once the ball seat is abraded, elastic displacement is increased, a gap is generated, the steering inner pull rod assembly is easy to loosen and lose effectiveness, the service life is short, and the steering comfort is relatively poor.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a turn to inner pull rod assembly is provided, when the ball seat wearing and tearing, the clearance can not appear in the assembly, and life is longer, turn to the travelling comfort better, can solve prior art's not enough.
The technical scheme of the utility model is that: the utility model provides a tie rod assembly in steering, includes casing, ball seat, ball round pin, the ball seat includes ball seat down and the last ball seat that is equipped with the inner chamber, ball round pin one end is connected in the inner chamber with last ball seat, down the ball seat and link to each other with last ball seat, lower ball seat is thermoplastic elastomer. The thermoplastic elastomer has the elasticity of rubber at normal temperature, and when the upper ball seat is worn and torn in the use process, the lower ball seat is subjected to elastic compensation, so that the assembly has no gap, the steering comfort is ensured, and the service life is prolonged.
Further, lubricating grease is coated on the inner cavity wall of the upper ball seat. The friction of the ball pin on the upper ball seat is reduced, the abrasion of the upper ball seat is reduced, and the service life is prolonged.
Further, the upper ball seat is made of engineering plastics. Has good high wear resistance and high yield strength performance, and further reduces the wear.
To sum up, the utility model provides a can reduce ball seat wearing and tearing, the clearance can not appear in the assembly when the ball seat wearing and tearing, uses the travelling comfort good, long service life's steering inner pull rod assembly.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Shown in the figure: a housing 1; a lower ball seat 2; an upper ball seat 3; a ball pin 4.
Detailed Description
The embodiment of the utility model provides a: as shown in fig. 1, a steering inner pull rod assembly, which comprises a housing 1, the ball seat, ball round pin 4, the ball seat includes ball seat 2 down and the last ball seat 3 that is equipped with the inner chamber, 4 one ends of ball round pin are connected in the inner chamber with last ball seat 3, lower ball seat 3 links to each other with last ball seat 3, lower ball seat 2 is installed in the appearance chamber bottom of casing 1, it is thermoplastic elastomer, go up ball seat 3 and install on the appearance chamber upper portion of casing 1, for having good high wear-resisting, the engineering plastics of high yield strength performance make, when last ball seat 3 takes place wearing and tearing in the use, lower ball seat 2 carries out the elastic compensation, the clearance can not appear in the assembly, the travelling comfort that has guaranteed to turn to, service life has.
In the preferred embodiment, grease is applied to the inner cavity wall of the upper ball seat 3. The friction of the ball pin 4 on the upper ball seat 3 is reduced, the abrasion of the upper ball seat 3 is reduced, and the service life is prolonged.
During assembly, an inner cavity of the upper ball seat 3 is coated with proper lubricating grease, then the lower ball seat 2 and the upper ball seat 3 are respectively placed into the shell 1, and finally the ball pin 4 is placed into the shell and is riveted and formed through a die and a hydraulic press. The performance of the steering inner pull rod assembly meets the requirements of a product starting moment, an average moment, an elastic rigidity test, an inner ball head pull-out force, an assembly endurance fatigue test and an assembly impact resistance test.
Claims (3)
