Abstract
The utility model discloses a rear steering knuckle of a four-linkage independent suspension, which comprises a steering knuckle body. The aluminum-alloy steering knuckle is processed and molded by a casting machine, and a rear hub bearing positioning reference hole, a connecting hole of a front upper swing arm, a connecting hole of a longitudinal swing arm, a connecting hole of a front lower swing arm, a connecting hole of a rear swing arm and a connecting hole of a rear shock absorber are arranged on the steering knuckle body. The connecting hole of the front upper swing arm, the connecting hole of the front lower swing arm and the connecting hole of the rear swing arm face an identical direction, and the axes of the three holes are parallel to or crossed with each other. The connecting hole of the rear shock absorber and the connecting hole of the longitudinal swing arm face an identical direction, and the axes of the two holes are parallel to or crossed with each other. The rear steering knuckle is simple in structure and easy in production, is light due to the fact that the rear steering knuckle is made of aluminum alloy and the weight of the rear steering knuckle is lightened by half of the weight of a punching-welding part with the same structure or the weight of cast iron with the same structure at least, and is small in energy consumption during production, less in environmental pollution and convenient in processing.
Description
Technical field
The utility model belongs to auto parts and components, is specifically related to a kind of connection bearing set of four connecting-rod separated suspensions.
Background technology
Manned vehicle in the present market is back axle many link-types independent suspensions that adopt of intermediate car especially more, back steering swivel is the parts of most critical in this pattern suspension frame structure, and it mainly acts on is to connect each swing arm of multi-connecting-rod separated suspension, hub bearing and brake caliper.Steering swivel adopts cast structure more behind the automobile of this suspension pattern of employing at present, and material generally adopts spheroidal graphite iron, this complex structure, positioning requirements height.
Summary of the invention
The purpose of this utility model is to provide steering swivel behind a kind of later-model four connecting-rod separated suspensions, to address the above problem.
The technical solution of the utility model is: steering swivel behind four connecting-rod separated suspensions, it comprises the steering swivel main body of the aluminum alloy of casting forging machinework moulding, offers the connecting bore of rear wheel hub bearing location datum hole, preceding top link, the connecting bore of trailing arm, preceding connecting bore, the connecting bore of rear-swing arm and the connecting bore of rear shock absorber of swing arm down on the steering swivel main body; Before the connecting bore of top link, the connecting bore of preceding swing arm down and the connecting bore of rear-swing arm towards identical, the parallel axes in three holes or intersection; The connecting bore of rear shock absorber and the connecting bore of trailing arm towards identical, the parallel axes in two holes or intersection.
The connecting bore of described trailing arm has two.
Described each hole is separately positioned on separately the brace table.
The utility model is simple in structure, is easy to produce; Lightweight, the material selection aluminum alloy, than same structure dash weldment and ironcasting weight reduces by 1/2nd at least; Energy consumption is little in the production process, and environmental pollution is littler; Easy to process.
Description of drawings
Slewing journal structure scheme drawing behind Fig. 1 four connecting-rod separated suspensions.
Steering swivel coupled condition scheme drawing behind Fig. 2 four connecting-rod separated suspensions.
The specific embodiment
As shown in Figure 1, according to the position of four connecting rods on vehicle, be provided with rear wheel hub bearing location datum hole 2 on the steering swivel main body 1 of the aluminum alloy of casting forging machinework moulding, the end face 3 of rear wheel hub bearing location datum hole 2 is the reference plane that is decided to be of this steering swivel.The connecting bore 4 of top link, the connecting bore 6 of preceding swing arm down, the connecting bore 7 of rear-swing arm before also being provided with on the steering swivel main body 1; Before the connecting bore of top link, the connecting bore of preceding swing arm down and the connecting bore of rear-swing arm towards identical, the parallel axes in three holes or intersection; Here towards identical and not exclusively be equal to the parallel axes in three holes, the axis in three holes also can intersect, and exists each other to be no more than 20 ° angle.Also be provided with the connecting bore 8 of rear shock absorber and the connecting bore 5 of trailing arm on the steering swivel main body 1, the connecting bore 8 of rear shock absorber and the connecting bore 5 of trailing arm towards identical, the parallel axes in two holes or intersection; Identical towards identical with above-mentioned description, here towards identical and not exclusively be equal to the parallel axes in two holes, the axis in two holes also can intersect, and exists between the axis in two holes to be no more than 20 ° angle.The connecting bore 5 of trailing arm has two.
As shown in Figure 1, 2, on the steering swivel main body 1 corresponding be provided with separately brace table on, promptly connect locating surface; It is respectively the connection locating surface 7.2 of brace table 7.1 of connecting bore 7 of connection locating surface 6.2, rear-swing arm of brace table 6.1 of connecting bore 6 of connection locating surface 4.2, preceding down swing arm of brace table 4.1 of the connecting bore 4 of preceding top link; The connection locating surface 8.2 of the brace table 8.1 of the connecting bore 8 of rear shock absorber,, with the brace table 5.1 of the connecting bore 5 of trailing arm be connected locating surface 5.2.Among Fig. 2, swing arm down behind top link, 10-trailing arm, the preceding swing arm down of 11-, the 12-, 13-rear shock absorber, 14-rear wheel hub bearing unit before the 9-.
