Description
Technical field
The utility model relates to a kind of constant velocity universal joint, relates in particular to a kind of anti-skidding universal joint ectosphere cage.
Background technique
Constant velocity universal joint is when master and slave moving axis has angular displacement, can transmitting movement and the mechanism of torque.
The structure of rzeppa universal joint of the prior art is that outer race and star sleeve are equipped with six raceway grooves, and six groove curvature centers of outer race and six groove curvature centers of star sleeve, be positioned at both sides, Rzeppa type retainer internal and external spherical surfaces center respectively, and throw of eccentric all equates, such raceway groove is provided with following deficiency: outer race and star sleeve all have six equally distributed raceway grooves on circumference, six steel ball work are arranged in rzeppa universal joint, do not make full use of enough inner spaces, bearing stress is lower; Six groove curvature centers of outer race and star sleeve all overlap, and when the universal joint transfer high torque, Rzeppa type retainer and steel ball can bear sizable stress because of the raceway groove biasing, cause breaking, and have shortened working life.
Prior art, it as the patent No. 200820150986.0,200820151703.4 the disclosed rzeppa universal joint of Chinese patent, above-mentioned rzeppa universal joint is not all established safeguard construction, when braking on wet and slippery road surface or in emergency braking, wheel surpasses the safe locking of frictional force on tire and ground easily because of braking force.
The model utility content
The purpose of this utility model provides a kind of anti-skidding universal joint ectosphere cage, and it has the advantages that to improve the universal joint stress-bearing capability and prevent wheel lock up, and the working life of having improved universal joint.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of anti-skidding universal joint ectosphere cage, it comprises outer race and is positioned at the retainer of outer race, steel ball, star sleeve that the outer race outer surface is provided with ABS anti-lock brake structure.Outer race one end is connected with the wheel skeleton, and star sleeve is located in the retainer, and star sleeve is fixedlyed connected with transmission shaft by the spline Placement; The stability of direction during braking still can be travelled by the track of assigned direction when being meant automobile brake; If because the emergency braking of automobile when especially running at high speed, and makes the complete locking of wheel, that is breakneck; If the front-wheel locking will make automobile lose steering capability; If whipping or tune will appear in rear lock, for example, sideslip or sideslip especially under the wet and slippery situation in road surface, are caused great harm to traffic safety; The braking force of automobile depends on the frictional force of break, but the braking force that automobile brake is slowed down also is subjected to the restriction of ground attaching coefficient; When the braking force of break generation increases to certain value, slippage will appear in automobile tire on the ground, and its slip rate is as follows:
δ＝(Vt-Va)/Vt×100％；
In the formula: δ--slip rate;
The theoretical velocity of Vt--automobile;
The actual velocity of Va--automobile;
Confirm according to test,, therefore,, must control its slip rate in 15% to 20% scope in order to obtain best braking effect when wheel slip δ reaches maximum value at 15% coefficient of attachment between 20% time; The function of ABS anti-lock brake structure promptly when wheel will locking, reduces braking force, and can not increase braking force during locking when wheel, and perseveration like this makes braking effect the best.
As of the present utility model preferred, described ABS anti-lock brake structure is the strip gear ring of being located on the outer race outer surface.
As of the present utility model preferred, outer race and star sleeve all are provided with eight raceway grooves, with steel ball number in the retainer that outer race, star sleeve match is eight, in eight raceway grooves of described outer race, wherein four raceway groove centers and inner ball surface centres, in addition there is throw of eccentric in four raceway grooves with the inner ball surface center, and concentric channel is interlocked with eccentric raceway groove and the five equilibrium arrangement; In eight raceway grooves of star sleeve, wherein four raceway groove centers and outer spherical surface centres, there is throw of eccentric in four raceway grooves with the outer spherical surface center in addition, and concentric channel is interlocked with eccentric raceway groove and the five equilibrium arrangement; Outer race is corresponding one by one with the concentric channel of star sleeve, and eccentric raceway groove is also corresponding one by one.Because the above-mentioned steel ball that is provided with does not apply any thrust load to retainer, is well suited for transmitting torque; Axially angle is made as 20 degree, has only four pairs of biasing control raceway grooves, and the staggered face of all the other four pairs of raceway grooves also can be controlled maximum axial angle, can improve bearing capacity, increases the service life.
In sum, the utlity model has following beneficial effect:
1, strengthen control to vehicle: be equipped with the automobile of ABS anti-lock brake structure, it is handling significantly that the driver still can keep in the emergency braking process, can in time adjust direction, and the obstacle or the dangerous situation of front are made timely, necessary hiding;
2, reduce hydro-planing: ABS anti-lock brake structure decrease the chance of wheel lock up, therefore also reduced and occurred slick and frivolous chance in the braking process;
3, effectively shorten stopping distance: under emergency braking condition, ABS anti-lock brake structure can make wheel be in the situation of not only rolling but also dragging, experimental results show that the ratio that drags accounts for about 20%, the frictional force maximum on tire and ground at this moment, promptly so-called best braking point or zone;
4, alleviated Tyte Wear: use ABS anti-lock brake structure to avoid the phenomenon of wheel lock up in the emergency braking process, avoided making tire to suffer the damage that to repair simultaneously, promptly avoided forming the possibility of flat spot at surface of tyre;
5, the distribution mode of the utility model channel structure and steel ball has improved the universal joint bearing capacity, prolongs its working life.
