Description
Technical field
The utility model belongs to motor vehicle assembly field of mechanical technique, particularly a kind of heavy motor vehicle rear suspension V-type distance rod assembly.
Background technology
The more advanced balance rear-pendant of present heavy motor vehicle generally assembles the individually balanced axle assembly in left and right, V-type propelling rod is utilized to realize the vertical and horizontal location of drive axle, transmit various force and moment, so V-type propelling rod is stressed, positioning element very important in equalizing suspension system.
V-type propelling rod is roughly divided into mount pad form and three bulb forms by structure.The two common ground is that two little ball head structure forms of vehicle frame end are substantially identical, difference is that the type of attachment of bridge end is different: the V-type propelling rod center axle end of three bulb forms is also provided with a ball head structure, physical dimension is larger, ball pin is installed in bulb inside, ball pin two ends are provided with holes, for being fixedly connected with of axle housing; The center axle end of mount pad form is provided with a mount pad, and mount pad flange is provided with four holes, for being fixedly connected with of axle housing.
The V-type propelling rod cost of three bulb forms is lower, and reliability is general, for stressed less tractor truck balance suspension; The V-type propelling rod cost of mount pad form is higher, and reliability is better, for the balance suspension of stressed comparatively severe tractor truck, dumping car.
In China, because dumping car overload is more, road conditions are poor, even if the V-type propelling rod of mount pad form is also subject to the puzzlement of reliability for a long time.
CN201120524897.X, publication date is: on December 26th, 2012, this utility model discloses a kind of vehicle and V-type propelling rod structure thereof, globoid is set as by the coupling end of the head by V-type propelling rod, and use two hemispherical recessed lids and two hemispherical spill liners and this globoid to form spherical pair, due to two hemispherical recessed lids with the use of, not easily to jail in fitting process, and easily in use because the vibration of machinery misplaces, V-type propelling rod was lost efficacy, thus reduces the service life of V-type propelling rod.
Because original design oscillating bearing inner ring is provided with taper hole, inner ring integral rigidity is reduced, or due to inside and outside taper hole taper fitting bad, vehicle mount pad after operation a period of time is deviate from suddenly from the taper hole of bearing inner ring, causes vehicle immobilization, the serious accident even causing car to turn over people to die.This failure mode still constantly occurs till now on heavy vehicles.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of heavy motor vehicle rear suspension V-type distance rod assembly, has stopped the failure mode that mount pad is deviate from from bearing inner ring, and the service life and the cost that improve whole V-type distance rod assembly low simultaneously.
The utility model is realized by following technical measures:
A kind of heavy motor vehicle rear suspension V-type distance rod assembly, is characterized in that, comprise liner ball seat, ball pin assembly, connection pipe, middle ball seat, oscillating bearing outer ring, mount pad, circlip and sealing sheath;
