Abstract
The utility model relates to a rzeppa universal joint capable of protecting a protective cover, which is used for a special vehicle. A sealing system is installed between the universal joint and a spline shaft countershaft. The inner chamber of the dirt-proof boot of the sealing system is a step-shaped through hole. Grooves are symmetrically arranged on the two sides of a raised platform at the end part of the dust-proof boot. The protective cover is additionally arranged outside the dust-proof cover. A skeleton is arranged in the protective cover. Under the same spatial conditions, the slip of the universal joint is larger, the allowable rotation speed is effectively improved and the dust-proof boot is not violently expanded and can still work reliably even under the condition of high rotation speed above 2500r/min; since the protective cover with the skeleton is added, the injuries caused by careless operation during the installation of a dust cover can be prevented, the foreign objects are prevented from puncturing the dust cover during working, the working reliability of the universal joint is improved and the service life of the universal joint is prolonged; and the rzeppa universal joint is particularly suitable for the transmission system of an off-road vehicle which is characterized in that the space arrangement is compact, the rotation speed is high, the wheel travel is large and the working condition is adverse.
Description
Technical field
The utility model relates to the universal joint that uses on a kind of special vehicle, the ball cage universal joint that has protective housing that particularly uses on the vehicle drive axle that travels on the cross-country road.
Background technique
As shown in Figure 3, be ball cage universal joint commonly used on the modern vehicle ransaxle, 8 is the fixed end universal joint, and 9 is dirt-proof boot, and 10 is jack shaft, and 11 are slippage end universal joint.A pair of dirt-proof boot is fixed on ball cage outer shroud and the axle with clip, and the effect of dirt-proof boot is to prevent that foreign matter from entering ball cage inside, prevents that simultaneously internal lubrication fat outwards runs off, and is important constituent element of ball cage universal joint.Continuous folding takes place around distortion in dirt-proof boot during universal joint work, so just requires dirt-proof boot to have good flexible, fatigue resistance and weatherability, generally makes with rubber.At present, the existing ball cage universal joint that has dirt-proof boot has the following disadvantages: 1, tensile buckling takes place in dirt-proof boot easily when stressed, when the universal joint high speed rotating, expand easily under centrifugal action, rotating speed is high more, and swell increment is big more, excessive swell increment not only can increase the rubber parts internal stress, quicken its inefficacy, might rub with extraneous other object simultaneously, cause the accident of dirt-proof boot to lose efficacy; 2, the intensity of rubber own is lower, is easy to be pierced, and causes the inefficacy of breaking then.So boot seal is a weak link of ball cage universal joint, a lot of failure of removal of ball cage are all caused by boot seal; 3, existing boot seal generally is " tower " formula structure as shown in Figure 3, and this tower dirt-proof boot generally adopts multi-layer structure in order to satisfy the maximum pendulum angle needs, and axial dimension is longer; Another deficiency of tower dirt-proof boot is to be easy to expand under high speed, so rotating speed allowable is lower, generally can not satisfy the system of vehicle transmission requirement that has wheel reductor.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of ball cage universal joint that can protect protective housing, to shorten the dirt-proof boot axial dimension, saves installing space, overexpansion takes place in the restriction dirt-proof boot when high speed rotating, increase the service life; Protect dirt-proof boot to avoid external force simultaneously and pierce through damage, improve reliability.
For achieving the above object, the technical solution of the utility model is: between first universal joint, second universal joint and the splined shaft axle pair on it sealing system is housed respectively.The dirt-proof boot inner chamber of universal joint sealing system is the ladder-type through hole, and boss both sides, dirt-proof boot end are symmetrical arranged fluted, is fixed on ball cage outer shroud and the axle with clip; Install safety cover additional in the boot seal outside, skeleton is arranged in the safety cover,, improve the reliability of dirt-proof boot, increase the service life in order to the protection dirt-proof boot.
The utility model is under the same space condition, the ball cage universal joint that this centre is sliding, have " cup " shape dirt-proof boot and safety cover, can allow universal joint that bigger slippage is arranged, effectively improve rotating speed allowable, even surpassing under the high speed conditions of 2500r/min, dirt-proof boot can acutely not expand, still can reliably working; Add and have the skeleton safety cover, the damage that causes because of careless manipulation in the time of can preventing from dust-proof cover is installed, and foreign object is stabbed dust-proof cover in the work, improves the universal joint functional reliability and also prolongs its working life; The utility model is highly suitable for that spatial arrangement is tightly short, rotating speed is high, wheel is jumped big, the abominable off-road vehicle transmission system of operating conditions.

Fig. 1 is a structure diagram of the present utility model;
Fig. 2 is the enlarged view of Fig. 1 sealing system;
Fig. 3 is the utility model prior art scheme of erection.
Embodiment
As shown in Figure 1 and Figure 2, first universal joint 1, second universal joint 7 with and on splined shaft axle pair 5 between sealing system is housed respectively, the inner chamber of the dirt-proof boot 2 of universal joint sealing system is the ladder-type through hole, outer rim is fluted, profile according to universal joint, two dirt-proof boots 2 are fastened on the outer shroud and axle of ball cage first universal joint 1, second universal joint 7 with two clips 4 respectively, boss both sides, dirt-proof boot 2 end are symmetrical arranged fluted, and the dirt-proof boot of this structure can satisfy bigger between centers angle requirement.In the proper functioning, under the between centers angle condition that is not more than 35 degree, can not produce the phenomenon of phase mutual friction between rubber; Down static, maximum angle can reach 40 degree.Axial dimension is short, can save installing space, and the extending amount of the spline that stretches in the middle of can increasing.The material of dirt-proof boot 2 generally is a neoprene, sulfuration process available heat pressing mold or injection mould; Safety cover 3 is equipped with in dirt-proof boot 2 outsides; this safety cover is made with high-strength rubber; inside is added with one deck and strengthens skeleton; further improve the intensity of safety cover 3, can not expand good toughness during this safety cover 3 high speed rotating; wear resistance is good; good weatherability generally can not pierced through by foreign object, can effectively protect dirt-proof boot 2.The sulfuration of safety cover 3 usefulness high-strength rubbers is made, and strengthening skeleton 6 can adopt the method moulding of hot-pressing die with materials such as nylon.The concrete geomery of dirt-proof boot 2, safety cover 3 is decided according to maximum pendulum angle requirement, the spatial constraints condition of universal joint.
