The invention discloses a dust proof and lubricating cardan joint for an automobile. The dust proof and lubricating cardan joint comprises a driving main shaft, a dust proof rubber sleeve and a fixing nut. The front end of the driving main shaft is embedded in a starlike sleeve, and steel balls are inlaid on the outer ring of the starlike sleeve. An extruding rod is arranged in a lubricating fluid extruding pipeline, and the outer end of the extruding rod is connected with a lubricating fluid pressing block. The lubricating fluid inlet is inlaid on the inner surface of the lubricating fluid extruding pipeline, and a lubricating fluid storage chamber is arranged at the rear end of the lubricating fluid extruding pipeline. A rubber plug is arranged on the lower surface of the lubricating fluid storage chamber. The rear end of a bell-shaped cover is connected with an output shaft, and dust proof rubber sleeve connectors are arranged on the two sides of the front end of the bell-shaped cover, wherein the dust proof rubber sleeve is nested at the left end of the driving main shaft. According to the dust proof and lubricating cardan joint for the automobile, lubricating oil is injected into a sliding groove where the steel balls move, so that the friction of the steel balls and a holder is reduced; and meanwhile, the dust proof rubber sleeve is additionally arranged on the outer ring of the driving main shaft to protect the cardan joint, so that dust is prevented from entering, and accordingly the service life of equipment is prolonged.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to a dust-proof and lubricated universal joint for automobiles. Background technique [0002] The universal joint is the universal joint, which is a machine that realizes variable-angle power transmission. It is used to change the position of the transmission axis direction. It is the "joint" part of the universal transmission device of the automobile drive system. The combination of universal joint and transmission shaft is called universal joint transmission. On vehicles with front-engine rear-wheel drive, the universal joint transmission device is installed between the output shaft of the transmission and the input shaft of the drive axle final drive; while the vehicle with front-engine front-wheel drive omits the drive shaft, the universal joint is installed Between the axle shaft of the front axle, which is responsible for both driving and steering, and the wheels.
