Abstract
The utility model discloses an abrasion-resisting piecing device of a car rear double bridge torque rod. The piecing device comprises a pin axle (1) and a pin axle sleeve (2) arranged on the pin axle, an inner axle sleeve (3) is fixed on the pin axle, the outer surface of the inner axle sleeve adopts a spherical surface, the two ends of the inner axle sleeve is provided with a lug boss (10) stretching outside, an outer axle sleeve (4) sleeved on the inner axle sleeve is fixed inside the pin axle sleeve, and the inner surface of the outer axle sleeve adopts a spherical surface matching the outer surface of the inner axle sleeve, a plurality of rolling balls and a rolling ball holder (12) separating each rolling ball are arranged between the outer surface of the inner axle sleeve and the inner surface of the outer axle sleeve, and a rubber gasket (5) is arranged between the two ends of the pin axle sleeve and the pin axle. The utility model changes the structure that the rotation and swing the traditional torque rod rubber joint assembly are realized through rubbing the rubber layer, and utilizes the cooperation among the rolling balls, the outer axle sleeve and the inner axle sleeve to realize the rotation and swing, therefore, the damage caused by friction is reduced, the performance of the car is further improved, and compared with the traditional ones, the service life is prolonged by 3-5 times.
Description
Technical field
The utility model relates to the torque rod connector device between the doube bridge of back in a kind of autotruck balancing suspension system.
Background technology
Traditional in the market rubber joint assembly of counteractive rod in autotruck, the annular end cap that it comprises bearing pin and is located at the axial two ends of bearing pin, part between the bearing pin at both ends lid has a spheroid, be filled with rubber between two end cap inner face and the spheroid, the pulling force work of automobile mainly moves by bearing pin friction loss rubber layer.After this structure was used certain hour, rubber layer occurred misfitting owing to the friction loss distortion and with the bearing pin operation, can directly have influence on the life-span of the tire of automobile, has potential safety hazard, and this structural joint assembly must directly be changed about 1 year at automotive operation.
The utility model content
The purpose of this utility model is to provide a kind of rub resistance, doube bridge torque rod connector device behind a kind of wear-resisting automobile of long service life.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: doube bridge torque rod connector device behind a kind of wear-resisting automobile, comprise bearing pin and the pin sleeve that is located on the bearing pin, be fixed with internal axle sleeve on the described bearing pin, the internal axle sleeve outside face is a sphere, the two ends of internal axle sleeve are provided with outward extending lug boss, described pin sleeve internal fixation has the outer shaft that is enclosed within on the internal axle sleeve, the inner face of outer shaft is the sphere that matches with the internal axle sleeve outside face, be provided with several balls and the ball retainer that each ball is spaced-apart between the outside face of described internal axle sleeve and the outer shaft inner face, be provided with rubber gasket between the two ends of pin sleeve and the bearing pin.
Owing to adopted above-mentioned structure, the rotation and the swing that have changed traditional rubber joint of counteracting rod in back assembly are carried out work by the friction glue-line, utilize ball, outer shaft, internal axle sleeve three's cooperation to realize rotating and swing work, having reduced friction damages, automotive performance is further enhanced, improve service life, its useful life is more traditional long 3-5 times.
