Description
Technical field
The utility model relates to rear overhang rack damping elastomer assembly, specifically is a kind of shock mount assembly.
Background technique
At present, heavy automobile integral balance rear-pendant structure comprises the damping of leaf spring one-level, also have and increase the rubber base damping device between leaf spring and the vehicle bridge, constitute rear suspension damping elastomer assembly, by spring and the damping of damping elastomer assembly two-stage, can effectively slow down the rigid impulse to vehicle bridge and vehicle frame.Heavy-duty car rear suspension damping elastomer assembly mainly is made up of parts such as slide plate, elastomer, lower plates.The lower end of slide plate is connected with the limit structure that cooperatively interacts by bearing pin with the upper end of lower plate.Upper head plate is connected with leaf spring, and Placement can be divided into the bolt jointing type and two kinds of the formulas of being slidingly connected substantially, and lower plate is fixedlyed connected with axle housing by screw thread.It is the damping elastomer that rear suspension damping elastomer assembly adopts rubber base, and its advantage is to have cancelled the centre bolt that is connected with leaf spring, assembles and keep in repair comparatively simple and fast.But shortcoming is owing to cancelled the centre bolt location, and rubber base can not limit the detaching motion of axle housing and vehicle frame, thus existing damping assembly adopt chain or up and down the interface arrangment of slide plate realize spacing.But because the impulsive load of heavy-duty car is bigger, very easily cause wearing and tearing and the fracture of limit structure, thereby cause vehicle bridge and vehicle frame to break away from accidents caused generation, have great potential safety hazard.
Summary of the invention
The purpose of this utility model is exactly the problem that exists for the solution prior art, and has designed a kind of shock mount assembly, not only guarantees its original effectiveness in vibration suppression, compares weight saving, the working life of having improved whole assembly with original structure.
The technical solution of the utility model is: a kind of shock mount assembly, comprise slide plate, elastomer and base, elastomer is arranged between slide plate and the base, described slide plate be provided with in the middle of the bottom surface dowel bushings from limit skateboard, the end face of described base be provided with dowel bushings from spacing base; Dowel bushings on slide plate and the base is hinged by a pin.
Described elastomer is two block rubber assemblies that are arranged on the lining both sides.
Described block rubber assembly comprises that upper and lower surface is converted into trapezoidal steel plate and middle some steel plates, is the high polymer elastic layer between the adjacent steel plate, and described high polymer elastic layer is one by sulfuration process and steel plate sulfuration, and longitudinal section becomes Octagon.
Describedly have mounting hole longitudinally from limit skateboard top, the lower surface of described mounting hole is cambered surface, and the one side relative with cambered surface is provided with median surface; In the middle of the described slide plate bottom face boss I is arranged, have 0 shaped pin hole in the boss I, pin can be up and down in pin-and-hole; The root of boss I and framework two ends are to cooperate and to prevent the inclined-plane that block rubber is deviate from the block rubber assembly.
Describedly comprising upper frame part and underframe part from spacing base, has two boss II in the middle of the described upper frame part, have the pilot hole that press-fits pin in the boss II, is groove between two boss II, and groove cooperatively interacts with boss I and is connected; Boss II root is to cooperate and to prevent the inclined-plane that block rubber is deviate from the block rubber assembly with the upper frame two ends; In the middle of the described underframe part stiffening rib is arranged, be provided with the mounting hole fixing with vehicle bridge around the underframe.
Further improvement of the utility model also has on spacing base the hole in one of two boss II to be processed into shoulder hole, the pin that is mated is processed into the ladder pin, and leave the mounting hole of clamp in the end of pin, can prevent after pin press-fits like this that pin is laterally mobile.Processing and lubrication oilhole in the middle of the pin regularly to pin and lining contacting point lubricating oil filling, improves the wear resistance of dowel bushings by oilhole.And bolt connect to replace pin and connects, by bolt and nut coupling together from limit skateboard with from spacing base.
The beneficial effects of the utility model can draw by such scheme: owing to adopt from limit skateboard with from spacing base, make the utility model tool anti-impact, wear resistance good, and have assembling safeguard simple, in light weight, cost is low, reliable performance, powerful characteristics.In addition when V-type track bar one side lost efficacy, assembly has certain lateral stiffness, can replace the V-type track bar to play the located lateral effect, automobile can continue to travel, the maintenance of entering the station again after the unloading, this has just been avoided vehicle heavy duty field maintenance, and garage can change easily damaged partss such as block rubber assembly voluntarily, and need not be again to before the same part go wrong and just change the whole assembly of neoprene bearing, reduced maintenance cost like this and improved repair quality and maintenance man's Security simultaneously.
This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is apparent.
