Abstract
The utility model discloses a spacing assembly of rubber sleeve area trip shaft includes that trip shaft, rubber sleeve and the interference that both ends were equipped with spacing ladder and recess respectively press the bush in the rubber sleeve, the laminating of the outer terminal surface of spacing ladder and bush, be equipped with packing ring and axial limiting plate in the recess, the laminating of packing ring medial surface and bush terminal surface, the packing ring outside is laminated with the axial limiting plate is inboard. The utility model discloses can save the maintenance cost of regular filling lubricating oil. Because the relative motion of the turnover shaft, the inner cylinder of the rubber sleeve and the engineering plastic bush is limited by the turnover shaft through the limiting step on the shaft and the mounting axial limiting plate, the relative displacement of the turnover shaft and the rubber sleeve caused by vibration is completely absorbed by the rubber in the rubber sleeve, and a better vibration reduction effect is achieved.
Description
Technical field
The utility model relates to the commercial-vehicle cab spacing technical field that suspends, and is specially the spacing assembly of a kind of rubber cuff trip shaft.
Background technology
In the Chinese utility model patent specification sheets that is CN201120285989.7 at application number, a kind of body suspension lining sleeve is disclosed, comprise metallic framework, rubber and aluminium core pipe, metallic framework, rubber and aluminium core pipe are sulfided into one, wherein, also comprise the connecting bushing of two ends for being fixedly connected with respectively with frame brackets with cab legs; In the outside wall surface of this connecting bushing, fixed cover is provided with rotary sleeve vertically, and in the outside wall surface of rotary sleeve, fixed cover is provided with aluminium core pipe vertically.But, must be around the trip shaft operator's compartment that overturns in the time that the parts of operator's compartment bottom need repairing, the trip shaft being now connected with cab rigid is corresponding rotation in rubber coating.In the time that Uneven road brings operator's compartment and chassis Relative Vibration, trip shaft is cushioned in rubber coating in the motion of rubber coating inner radial both direction, axially can free motion can not get buffering.In rubber coating, be press-fitted taking metallic material as main composite bush or metal sleeve, trip shaft is through composite bush or metal sleeve.Under the long rotary action of trip shaft, bring the severe wear of axle and lining or sleeve pipe, reduce the reliability and the safety of vehicle that connect, and the post gap increase of mutually wearing and tearing of axle and lining or sleeve pipe, generation abnormal sound; And trip shaft axial infinite place in rubber coating, axial motion can not get the buffering of rubber coating, and occupant is obvious to the seismesthesia from left and right directions in operator's compartment.
Summary of the invention
The purpose of this utility model is to provide a kind of wearing and tearing that can reduce trip shaft and lining itself in order to overcome above-mentioned deficiency, has played again the spacing assembly of rubber cuff trip shaft of good effectiveness in vibration suppression.
The spacing assembly of the utility model rubber cuff trip shaft comprises that two ends are respectively equipped with the trip shaft of spacing ladder and groove, rubber coating and interference and press fit over the lining in rubber coating, the outer face laminating of described spacing ladder and lining, in described groove, be provided with packing ring and axial limiting plate, described packing ring medial surface and bush end face laminating, described packing ring outside and the laminating of axial limiting plate inner side.
As the further improvement of the spacing assembly of the utility model above-mentioned rubber cuff trip shaft, described lining is engineering plastics lining.
As the further improvement of the spacing assembly of the utility model above-mentioned rubber cuff trip shaft, described packing ring is metal washer.
The beneficial effects of the utility model are as follows: owing to being press-fitted engineering plastics lining in rubber coating, engineering plastics lining has that coefficient of friction is little, resistance to abrasion good and possess self-lubricating function, thereby the wearing and tearing of trip shaft and engineering plastics lining itself, the maintenance cost that can also save regular charging-up lubricant oil are reduced.The relative motion to positioning plate restriction trip shaft and rubber coating inner core, engineering plastics lining by the limited step on axle and installation shaft due to trip shaft, the trip shaft that vibration brings and the relative displacement of rubber coating are all absorbed by the rubber in rubber coating, have played good effectiveness in vibration suppression.
Read by reference to the accompanying drawings after the detailed description of the utility model embodiment, other features of the present utility model and advantage will become clearer.
Brief description of the drawings
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, wherein:
Fig. 1 is the utility model structural representation.
Fig. 2 is A-A cutaway view in Fig. 1.
Fig. 3 is trip shaft structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention of the present utility model, the spacing assembly of the utility model rubber cuff trip shaft is made the following instructions.
Embodiment: the utility model comprises that two ends are respectively equipped with the trip shaft 3 of spacing ladder 1 and groove 2, rubber coating 4 and interference press fit over the lining 5 in rubber coating 4, lining 5 is preferably selected engineering plastics lining, lining 5 is enclosed within on trip shaft 3 and adopts free-running fit, trip shaft 3 can freely rotate lining 5 is interior, therefore realized the outer face laminating of the spacing ladder 1 of turn over function with the lining 5 of operator's compartment, in groove 2, be provided with packing ring 6 and axial limiting plate 7, the other end of trip shaft 3 penetrates packing ring 6, packing ring is selected metal washer, the respective ends end face face laminating of the inner side end of packing ring 6 and lining 5, axial limiting plate 7 embeds in groove 2, when trip shaft 3 is installed, bolt is through axial limiting plate 7 hole corresponding with trip shaft 3, compression axis is to positioning plate 7, by the limited step 1 of trip shaft 3 and the combined action of axial limiting plate 7, realize the axial limiting of trip shaft 3 in rubber coating 4.Therefore, after vibration passes over, the inner core of trip shaft 3 and rubber coating 4, lining 5 are without relative motion, and vibration is converted into the distortion of rubber between rubber coating 4 urceolus and inner core, has realized the vibration-damping function of rubber.
Because engineering plastics lining has, coefficient of friction is little, resistance to abrasion good and possess self-lubricating function, thereby has reduced the wearing and tearing of trip shaft and engineering plastics lining itself, the maintenance cost that can also save regular charging-up lubricant oil.Trip shaft is the relative motion to positioning plate restriction trip shaft and rubber coating inner core, engineering plastics lining by the limited step on axle and installation shaft.The trip shaft that vibration brings and the relative displacement of rubber coating are all absorbed by the rubber in rubber coating, have played good effectiveness in vibration suppression.
Above-described embodiment is preferably embodiment of the utility model; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
