Abstract
The utility model relates to a universal joint assembly which comprises a universal joint pin. Shaft heads are arranged on the universal joint pin in all cross directions respectively. A shaft sleeve is arranged outside each shaft head in a sleeved mode and is connected with the shaft head through a bearing. The tail portion of each shaft sleeve is sealed with one shaft head through an oil seal. Each oil seal comprises an oil seal body and an oil seal framework, wherein the oil seal framework is arranged outside the oil seal body and is pressed with the oil seal body to form a whole. A plurality of circular beads are arranged at the position, corresponding to one shaft head, of each oil seal body. Adjacent circular beads are connected through a connecting piece with an inclination. The oil seals are in interference fit with all the circular beads. The universal joint assembly is simple in structure, and not only has good sealing performance but also can prolong the service life of a universal joint.
Description
Technical field
The utility model relates to a kind of engineering, machinery part, especially relates to a kind of universal joint assembly.
Background technique
Universal joint is universal joint, and English name universal joint is the parts of realizing the varied angle transmission of power, is used for needing to change the position of transmission axial direction, and it is " joint " parts of the universal driving device of automobile driving system.Universal joint and transmission shaft combination are called card gear.
The structure of universal joint and effect are a bit as the joint on the human limb, and the angle between the part that it allows to be connected changes within the specific limits.For satisfying transmission of power, adapt to the angle that the bob that produces when turning to automobilism causes and change, universal joint commonly used links to each other between the ransaxle of front drive automobile, semiaxis and wheel shaft.But owing to be subjected to the restriction of axial dimension, require the drift angle bigger again, the instantaneous angular velocity that single universal joint can not make output shaft and axle go into axle equates, cause vibration easily, the damage of aggravation parts, and produce very big noise, so extensively adopt constant velocity universal joint miscellaneous.On front drive automobile, each semiaxis is with two constant velocity universal joints, is inboard universal joint near the universal joint of transaxle, and near axletree is outboard universal joint.On rear-drive automobile, on vehicle frame, and ransaxle is connected with vehicle frame by resilient suspension, and a distance is arranged between the two, need connect as an integral installation for motor, clutch and speed changer.Uneven road produces and beats in the automobilism, the potential difference of load variations or two assembly installations etc., the capital makes angle and the distance between transmission output shaft and the ransaxle main reducing gear input shaft change, therefore the universal joint type of belt drive at rear-drive automobile all adopts double Hooke's joint, be exactly that the transmission shaft two ends respectively have a universal joint, its effect is that the angle at transmission shaft two ends is equated, thereby guarantees that output shaft equates all the time with the instantaneous angular velocity of input shaft.
According to large-scale universal joint assembly applying working condition, generally all under humidity, dust rugged environment, use.The outside framework oil seal that existing universal joint assembly uses generally has only a shoulder sealing, loses efficacy as a shoulder, will cause water, dust etc. to enter universal joint, will have a strong impact on its working life.
The model utility content
In order to overcome the deficiency that prior art exists, the utility model provides a kind of universal joint assembly of good seal performance.
A kind of universal joint assembly, comprise cross axle, be respectively equipped with spindle nose on the cross direction of described cross axle, described spindle nose is arranged with axle sleeve outward, be connected by bearing between described axle sleeve and the spindle nose, seal mutually by oil sealing between the afterbody of described axle sleeve and the spindle nose, described oil sealing comprises the oil sealing body and is arranged on the oil sealing body exterior and is compressed to the oil tight skeleton of one with the oil sealing body, the corresponding spindle nose position of described oil sealing body is provided with several shoulders, connects by the link with gradient between the described adjacent shoulder; Adopt interference fit between described oil sealing and each shoulder.
Preferably, the quantity of described shoulder is three.
Preferably, adopt the oblique angle transition between described shoulder and the link.
Preferably, described oil tight skeleton is L-shaped circular.
Oil tight skeleton described in the utility model can adopt iron frame, and the oil sealing body can adopt high-temperature resistant rubber, and oil sealing can be formed by iron frame and high-temperature resistant rubber compacting.
The utility model is simple in structure, not only has good sealability, and can prolong universal joint working life.
