Abstract
The utility model relates to a pitman arm device for a passenger car independent suspension. The pitman arm device for the passenger car independent suspension comprises a pitman arm and a pin shaft, wherein the pin shaft is installed in an inner hole of the pitman arm in a penetrating mode, and the pitman arm is connected with the pin shaft through a bearing. The bearing is an integral lubrication-free double-row tapered roller bearing, the inner ring of the bearing is pressed tightly through a round nut and a lock washer, and the outer ring of the bearing is pressed tightly through a converter blanking cap. The bearing between the pitman arm and the pin shaft of the pitman arm device is designed to be the integrated bearing which is lubrication-free, the interior of the bearing is completely isolated from the outside, oil does not need to be added to lubricate the bearing after the bearing is installed, and lubrication of the bearing is totally dependent on lubricating oil existing inside the bearing so that impurities such as dust can be effectively prevented from entering the interior of the bearing from an oil filling hole, cleaning inside the bearing is ensured, thus service life of the bearing is ensured, and safe and stable driving of a passenger car is ensured.
Description
Technical field:
The utility model relates to a kind of passenger vehicle parts technical field, is specifically related to a kind of passenger vehicle independent suspension pitman arm device.
Background technology:
Develop rapidly along with society, the raising of people's living standard, simultaneously at home under the background of bus industry and the manufacturing high speed development of parts thereof, market is also more and more higher to the requirement of the stability of passenger vehicle, traveling comfort, and no longer contents just to its transportation function.Suspension system is playing crucial effects aspect the traveling comfort of vehicle, and wherein the air independent suspension has obtained the approval in market with its superior stiffness characteristics, and the utilization in passenger vehicle is more and more general.
Air independent suspension good comfort, will be based on each parts lightweight and good safety and reliability, the pitman arm device is indispensable parts on the air independent suspension, it is one of assurance of bus safety smooth operation, at present, the pitman arm device of passenger vehicle air independent suspension, mainly comprise pitman arm, be connected with the rocking arm bearing of usefulness of bearing pin and bearing pin, its centre bearer is the critical component in the pitman arm, the normal use of bearing is the prerequisite basis of pitman arm safe operation, in case bearing failure causes the rocking arm inwall easily and damages, the lubricated of bearing then is the basis of bearing safe and stable operation, it also is the bearing assurance in service life, what the bearing that uses in the existing pitman arm adopted mostly is outer lubricated, namely want regularly bearing to be maintained oiling, in actual use, lubricating oil refuels loaded down with trivial details, and dirt impurity enters bearing inside from the filler port of bearing easily, accelerate the damage of bearing, can't guarantee the service life of bearing, influence the traveling comfort of passenger vehicle, and travel for the safety and stability of passenger vehicle and cause potential safety hazard.
The utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of passenger vehicle independent suspension pitman arm device, it is with the pitman arm of pitman arm device and being integral of the design bearing bearing between the bearing pin, adopt nonlubricated bearing, bearing is inner isolated fully with the external world, do not need oily in addition after bearing is installed, the lubricated inner lubricating oil that self has of bearing that relies on fully of bearing, but actv. prevents that impurity such as dust from entering bearing inside from filler port like this, guarantee the cleaning of bearing inside, thereby guarantee the service life of bearing, guarantee stable the travelling of bus safety.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of passenger vehicle independent suspension pitman arm device, comprise pitman arm and bearing pin, wherein: bearing pin is installed in the endoporus of pitman arm, and be connected by bearing between pitman arm and the bearing pin, bearing is that integral body is exempted from the lubricated type double-row conical bearing, bearing inner ring compresses by circular nut and stop washer, and outside race compresses by the conv blanking cover.
Further, described bearing two ends, the slit between bearing inner ring and the outer ring seals by seal ring.
Further, described seal ring is outside framework oil seal.
The beneficial effects of the utility model are:
1, the utility model is with the pitman arm of pitman arm device and being integral of the design bearing bearing between the bearing pin, adopt nonlubricated bearing, bearing is inner isolated fully with the external world, do not need oily in addition after bearing is installed, the lubricated of bearing relies on the inner lubricating oil that self has of bearing fully, but actv. prevents that impurity such as dust from entering bearing inside from filler port, the cleaning of assurance bearing inside like this, thereby guarantee the service life of bearing, guarantee stable the travelling of bus safety.
2, the utility model is simple in structure, easy to use, need assembly part few, fitting process is simple to operation, loading error can not occur, improve production efficiency greatly, save production and human cost, for the car load steering swivel system, it is less that the utility model rotates required twist moment, and the bearing two ends urgent moment that tights a bolt is less, can improve bearing service life.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of passenger vehicle independent suspension pitman arm device, comprise pitman arm 1 and bearing pin 2, bearing pin 2 is installed in the endoporus of pitman arm 1, and is connected by bearing 3 between pitman arm 1 and the bearing pin 2, bearing 3 is exempted from the lubricated type double-row conical bearing for integral body, bearing 3 inner rings compress by circular nut 4 and stop washer 5, and bearing 3 outer rings compress by conv blanking cover 6, bearing 3 two ends, slit between bearing 3 inner rings and the outer ring is by seal ring 7 sealings, and seal ring 7 is outside framework oil seal.
Be noted that, above-described embodiment is to the explanation of technical solutions of the utility model and unrestricted, other modification that is equal to replacement or makes according to prior art of affiliated technical field those of ordinary skill, as long as do not exceed thinking and the scope of technical solutions of the utility model, all should be included within the desired interest field of the utility model.
