Abstract
The utility model relates to a roller pin type central rocker arm bushing for a vehicle. A bushing assembly whose exterior is fixed with a vulcanized rubber buffer layer is simultaneously used as an outer ring 5 of a rolling pair, and an integral of a rotary rolling type rubbing pair with a buffering function is formed by the bushing assembly, a built-in needle roller 2, an inner ring 3, and a retainer rings 1 between the needle roller and the inner ring together. The utility model has the advantages of small frictional resistance, high bearing capacity, economy and utility, simple structure, good durability, and convenient installation. The rotary rolling type rubbing pair is pressed on the central rocker arm bushing. Because a matching surface does not have relative slip, the premature abrasion of the bushing is avoided, and the 'shiver' problem caused by the looseness of the bushing in a running system of the automobile can be fundamentally eliminated.
Description
The utility model relates to the needle-type central authorities rocker arm bush of a kind of automobile steering system, particularly mid-get car steering swivel system.
The central rocker arm bush of automobile steering system in the past, the sliding structures that adopt at metallic sheath outside face polysulphide rubbers more, this structure, although at the use initial stage, rubber layer passes the vibrations to control wheel to ground, wheel, can play buffer action, but the revolute pair friction drag is big, particularly, influenced maneuvering performance owing to serious wear day by day, spacious " shiver " phenomenon that causes automobile traveling system to produce of lining pine; Also having a kind of patent No. in addition is 942016173 steel-ball type central authorities rocker arm bushs, though becoming steel ball with revolute pair, this structure cooperates with rolling between metal axle sleeve, rubber and intermetallic wearing and tearing have been avoided, friction drag has reduced, but required part increases, the accumulation of error increases, precision reduces, and increasing owing to take up room, so that have to change the original steering trapezium structure of automobile steering system, cause steering swivel system path of motion to change, and in order to reduce oad as far as possible, have to adopt the less steel ball of diameter, from and caused the reduction of load-carrying capacity, simultaneously, owing to due to the structure, need during installation to adjust, return production operation and make troubles.
The purpose of this utility model, aim to provide that a kind of friction drag is little, load-carrying capacity is big, simple in structure, good manufacturability, central rocker arm bush that durability is strong, it neither changes the trapezium structure of the original steering swivel system of automobile, and " shiver " phenomenon that can fundamentally avoid automobile traveling system to occur.
The technical scheme that adopts is for achieving the above object: install with central rocking arm cooperates, outside vulcanize admittedly in the lining outer shroud of yielding rubber layer, put lining interior ring and needle roller, add spacing back-up ring, constitute the monolithic devices bush assembly of a rolling friction pair.Dress is used for central rocking arm.Its endoporus is connected with the pivot pin of the preceding fine strain of millet of automobile.
The central rocker arm bush of this needle-type, simple in structure, good manufacturability, precision height, friction drag is little, bearing capacity is big, occupy little space, because there is not slide relative in its mating surfaces, under the situation that does not change the original steering swivel system trapezium structure of automobile, the lining premature wear of having avoided rubber and metal friction and having caused, thereby, fundamentally eliminated " shiver " phenomenon that occurs in the automobile traveling.
Below in conjunction with accompanying drawing,, be described in further detail specific embodiments of the present utility model:
Accompanying drawing is the overall structure signal of central rocker arm bush.
The central rocker arm bush of needle-type automobile of the present utility model shown in the accompanying drawing, the monolithic devices bush assembly of forming a rolling friction pair by back-up ring 1, needle roller 2, interior ring 3, damping polysulphide rubbers layer 4 and outer shroud 5, back-up ring wherein is in order to the end float misalignment of ring 3 and outer shroud 5 in limiting.During installation, earlier the rubber layer with the lining outer shroud is pressed in the mounting hole of central rocking arm, and then annular distance in the central rocking arm of belt material cover is set on the pivot pin of fine strain of millet before the automobile, and is fastening by being spirally connected, and need not adjustment.
Claims (1)
- The central rocker arm bush of a kind of needle-type automobile, constitute by bush assembly and bearing, it is characterized in that: vulcanize admittedly outside in the lining outer shroud (5) of yielding rubber layer (4), put ring (3) and needle roller (2) in the lining, add back-up ring (1), constitute the monolithic devices bush assembly of a rolling friction pair.
