Abstract
Provided is a backward-turning rubber bearing used for a heavy truck cab. The backward-turning rubber bearing used for the heavy truck cab is provided with a metal outer tube and a metal inner tube. Composite elastomer is arranged between the metal outer tube and the metal inner tube. The outer circumference of the metal outer tube is of a double-horn-shaped structure with the middle being small and the two ends being large and the two ends of the metal inner tube are provided with chamfers. According to the backward-turning rubber bearing used for the heavy truck cab, the composite elastomer is arranged between the metal outer tube and the metal inner tube, and the outer circumference of the metal outer tube is made to be of the double-horn-shaped structure with the middle being small and the two ends being large, so that a drag hook connected to the surface of the bearing can move limitedly within a small outer circumferential region in the middle of the metal outer tube to relieve impact, and the backward-turning rubber bearing has higher practical value.
Description
Technical field
The utility model belongs to auto parts machinery manufacturing technology field, is specifically related to a kind of rear upset rubber bush bearing for cab of heavy truck.
Background technique
The bearing that overturns after operator cabin is lorry I class fragile part, it is arranged on after operator cabin in switching mechanism, play the effect of fixing, buffering, damping and stressed transmission, the damping of operator cabin, soundness, Security and maintain and replace convenience are played to significant role.In the market for the cab mounting support of lorry, structure is single, directly with steel pipe, process, be arranged on after operator cabin in switching mechanism, in load-carrying vehicle running process, impact force is directly delivered to operator cabin by the bearing that overturns after operator cabin, in impact force transmittance process, there is no damping device, impact process is also endergonic process, and load-carrying vehicle operator cabin spoilage is always high.The bearing that overturns after existing operator cabin is short working life, has not only increased user's operation cost, has reduced complete vehicle quality simultaneously, has increased enterprise operation cost, and after-sales service workload is rolled up, and is therefore necessary to propose to improve.
Model utility content
The technical problem that the utility model solves: a kind of rear upset rubber bush bearing for cab of heavy truck is provided, between metal outer pipe and metal inner pipe, be provided with composite elastic body, the large Double-horn type structure in little two ends in the middle of simultaneously the excircle of metal outer pipe being made, makes the drag hook that bearing surface connects in the middle little outer circumferential area of metal outer pipe, limited movement slow down impact.
The technical solution adopted in the utility model: for the rear upset rubber bush bearing of cab of heavy truck, there is metal outer pipe and metal inner pipe, between described metal outer pipe and metal inner pipe, be provided with composite elastic body, wherein, the large Double-horn type structure in little two ends in the middle of the excircle of metal outer pipe is, metal inner pipe two ends are shaped with chamfering.
Further, described metal outer pipe punching press is made.
Further, in the middle of the excircle of described metal outer pipe, little position seamlessly transits to large position, excircle two ends.
The utility model advantage compared with prior art:
1, simple in structure, cheap for manufacturing cost, easy to use, elastomeric material Compression and Expansion intensity is high, and rebound elasticity is good, and wear resistance, ageing resistance and damping, buffering performance significantly improve, and operator cabin is significantly improved working life;
2, improve car load driving safety, reduced tare, reduced user's operation cost, reduced to a great extent after-sales service workload, improved the overall performance of lorry;
3, the drag hook connecting on workpiece can the region between the horn mouth of metal outer pipe both sides in limited movement, by movement, can effectively slow down the impact force that cab turning mechanism is subject to.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structure side view.
Embodiment
Below in conjunction with accompanying drawing 1,2, a kind of embodiment of the present utility model is described.
Rear upset rubber bush bearing for cab of heavy truck, there is metal outer pipe 1 and metal inner pipe 2, between described metal outer pipe 1 and metal inner pipe 2, be provided with composite elastic body 3, wherein, the large Double-horn type structure in little two ends in the middle of the excircle of metal outer pipe 1 is, in the middle of the excircle of described metal outer pipe 1, little position seamlessly transits to large position, excircle two ends; Metal outer pipe 1 selects toughness and the better material of wear resistance to be stamped to form, withstand voltage and wear-resisting property significantly promotes, the large Double-horn type in little two ends in the middle of the structure of metal outer pipe 1 excircle is, such structural advantages is the limited movement in region that the drag hook that connects on workpiece can be between metal outer pipe 1 both sides horn mouth, by movement, can effectively slow down the impact force that cab turning mechanism is subject to.Inner tube 2 is made for metal tube, and the inside and outside chamfering in two ends makes its convenient to load and transport more when press-fiting, and is conducive to composite elastic body 3 simultaneously and fills up completely between metal outer pipe 1 and metal inner pipe 2.
Working principle: be delivered to while overturning rubber bush bearing after operator cabin from the impact force of wheel, the drag hook that bearing surface connects on the one hand can limited movement slow down impact in the middle little outer circumferential area of metal outer pipe 1, the composite elastic body 3 of bearing inside also can effectively absorb the impact force that it is subject on the other hand, thereby realizes fixedly operator cabin and switching mechanism after operator cabin is played to damping, buffer function.The utility model is compared to the prior art compared with apparatus with shock absorbing, damping, buffering better effects if.The composite elastic body of being made by compounded rubber 3 ageing-resistant performances that the utility model is used are simultaneously high, wear-resisting property is good, be 12-18 month working life, therefore truck after sale guarantee time can extend to more than 1 year, greatly improve in lorry the working life of switching mechanism and operator cabin after operator cabin, reduced truck manufacturer and user's user cost.
Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting the utility model practical range, and the equivalence of being done with content described in the utility model claim therefore all changes, within all should being included in the utility model claim scope.
