The floating spindle sleeve is simple in structure, long in service life, easy to assemble and maintain, and relatively high in traveling stability and safety, improves shock absorbing and buffering performance by a large scale, and can be widely used for motor lorries.
Description
One, technical field
The utility model relates to a kind of rubber shock-absorbing buffer structure spare for truck cab's front overhang overturning unit, and specifically a kind of floating buss belongs to vehicular spare parts manufacturing technology field.
Two, background technology
Floating buss is autotruck I class fragile part, is installed in the front suspending of heavy truck cab part, plays the effect of buffering, damping and stressed transmission, and traveling comfort, stationarity, safety and the maintain and replace convenience of driving played significant role.The axle sleeve that is used for truck cab's front overhang on the Vehicles Collected from Market mainly contains steel bushing and polyurethane axle sleeve, and steel bushing is directly used steel pipe is set in the front overhang system, plays inverting action, although structure is simple, this steel bushing cushions, damping performance is very poor.Although polyurethane axle sleeve resistance to abrasion is good, its rigidity can not satisfy domestic autotruck actual travel rto request, and service life is shorter.During present domestic axle sleeve used, autotruck front-suspension componental movement was steady not, smooth and easy, and torsional deflection and retardance phenomenon are arranged.Damage enormous amount, and the comfort level of operator's compartment is low, has increased enterprise and user's operation cost, has strengthened enterprise's after-sales service work capacity, has restricted to a certain extent the development of enterprise.
Three, utility model content
The utility model mainly is to adopt old-fashioned homogenous material accessory in order to solve existing truck cab front overhang axle sleeve, its buffering, damping performance are poor, service life is short, the front-suspension componental movement is steady not, smooth and easy, torsional deflection and retardance phenomenon are arranged, thus a kind of new technical scheme that proposes.
For achieving the above object, the utility model can be realized by following scheme:
A kind of floating buss, it is to be constituted by floating buss main body and dustproof lid, the floating buss main body by mandrel, inner sleeve and the overcoat of concentric different radii successively mutually socket form, the compound elastic body that is provided with between mandrel and inner sleeve, inner sleeve and overcoat, be provided with dustproof lid at floating buss main body two ends, dustproof lid is to be fixed with respectively wiper of rubber and lower wiper of rubber on upper cover of dust and lower cover of dust; In the mandrel inner sleeve inner sleeve is arranged, inner sleeve mutually inserts with mandrel and is connected; The pipe sidewall of described inner sleeve and overcoat is non-enclosed construction, and the cross section is the C character form structure.
Is provided with hole in the middle of described upper cover of dust and the lower cover of dust, the edge is chamfering structure, and it is along the corresponding one side of circumference compound upper wiper of rubber and the lower wiper of rubber of being provided with respectively; Mandrel is the hollow cylinder structure; Sidewall of the inside race is provided with hole.
The advantage that the utility model compared with prior art has is: simple in structure, easy to install, elastomeric material Compression and Expansion intensity is high, and rebound resilience is good, and resistance to abrasion, resistance to ag(e)ing and damping, buffering performance significantly improve.Can greatly improve the service life of shock absorption buffering mechanism in the autotruck.

Five, the specific embodiment
With specific embodiment the utility model is described in further details by reference to the accompanying drawings now:
A kind of floating buss, it is to be made of floating buss main body and dustproof lid, be socketed with dustproof lid at floating buss main body two ends exactly, and dustproof lid is to plug formation by inner sleeve 4, the floating buss main body is the metallic material mandrel 1 by concentric different radii, inner sleeve 2 and overcoat 3 mutually insert successively socket and form, in mandrel 1 and inner sleeve 2, the compound elastic body that is provided with 7 is elastomeric materials between inner sleeve 2 and the overcoat 3, be respectively equipped with wiper of rubber 8 and lower wiper of rubber 9 at upper cover of dust 5 and lower cover of dust 6 corresponding surfaces, described mandrel 1 is hollow structure; Described inner sleeve 2 and overcoat 3 are non-closed circular tubular constructions, the c-shaped structure of its cross-sectional plane; Be provided with hole in the middle of described upper cover of dust 5 and the lower cover of dust 6, the edge is chamfering, along compound upper wiper of rubber 8 and the lower wiper of rubber 9 of being provided with of circumference.The whole side of floating buss is provided with the plane, has interests to place and install.
Principle of work is:
Be used for heavily blocking the rubber shock-absorbing buffering floating buss of cabin front suspension overturning unit, that mandrel 1 is in the same place inner sleeve 2 and overcoat 3 composite joints by elastic body 7 elastomeric materials, inner sleeve 2 sidewalls are provided with hole, better connect into mandrel 1 and inner sleeve 2, overcoat 3 as a whole; The breakaway-element unitized construction that upper cover of dust 5, lower cover of dust 6 and elastic body 7 elastomeric materials are bonded together.Overcoat 3 rocking arm holes are closely supporting, thereby realize that operator's compartment heavily blocks the cabin front suspension inverting action, the disposable rocking arm hole that is pressed into of floating buss main body that mandrel 1, inner sleeve 2, overcoat 3 and elastic body 7 is combined into press mounting tool, again φ 16 bolts are connected upper cover of dust 5 by the inner sleeve 4 that is assemblied in the mandrel 1 with lower cover of dust 6 and both sides hanger, rear fixing in the hanger outside with nut, greatly improved the service life of shock absorption buffering mechanism in the autotruck.The product processing cycle shortens, and the accurate standardization level of its size is high, and is moderate with the matching allowance in rocking arm hole, and assembling and maintain and replace are easily convenient, time saving and energy saving.
