Abstract
The invention relates to a rear suspension assembly of a full-floating high-rigidity passenger car. A stabilizer bar (15) of the rear suspension assembly is positioned outside a trailing arm shaft tube (6). The stabilizer bar (15) is connected with a left trailing arm (2) and a right trailing arm (2) by a spine and a rear axle shaft tube (9) and is provided with locking devices (12, 13, 14). The rear axle shaft tube (9) and the trailing arm shaft tube (6) are connected with a bracket (8) into a whole by closing fitting. Two needle bearings (4, 7) are moved and positioned between the trailing arms (2). The inner bearing (7) is combined with an oil seal, and the outer bearing (4) is provided with an outer end cover. The trailing arms (2) are provided with oil feeding holes (16). A limiting part suspended in the middle of the trailing arms (2) adopts a structure that trailing arm bodies are additionally provided with T-shaped reinforcing ribs. The rear suspension assembly of the passenger car easily realizes the concentricity of the rear axle shaft tube assembly, remarkably improves the strength and rigidity of the trailing arms and can effectively prevent water from entering the rear axle shaft tube.
Description
Technical field
The present invention relates to a kind of rear suspension assembly of full-floating high-rigidity passenger car.
Background technology
Family expenses manned vehicle rear suspension assembly is the important assembly parts of of manned vehicle chassis, its reasonableness structurally directly affects the stable and safety performance of car, simultaneously also affect the life-span and the maintenance of passenger-car chassis, but also can the parts that rear suspension assembly connects mutually be affected.
Shown in Fig. 1 (a), Fig. 1 (b), existing family expenses manned vehicle rear suspension assembly is by back axle central siphon (9), support one group of parts such as (8), wait another group part with trailing arm (2), trailing arm central siphon (4), form swing by two needle bearings (7,10), and stabilizer rod is built-in.Its main deficiency is:
A. two needle bearings (7,10) on back axle central siphon (9), the trailing arm central siphon (4) are loaded on respectively on back axle central siphon (9) and the support (8), work in-process is difficult to guarantee right alignment, make rear overhang hang assembly and in operational process, will produce distortion inevitably, finally cause preceding tires inclination deviation, influence the rideability of car load;
B. back axle central siphon (9) is sealed at both ends bad, advances muddy water easily, makes bearing and the corrosion prematurely of back axle central siphon, greatly reduces service life, has also increased maintenance cost simultaneously.
C. stabilizer rod is built-in, and stabilizer rod and trailing arm central siphon (4) are easy to generate collision in running car, produce peculiar noise, and simultaneously stabilizer rod is accelerated with trailing arm central siphon (4) wearing and tearing, has the individual user to reflect to travel 5000 kilometers noises just very big, makes the stability reduction.
D. the stop portion in the middle of the trailing arm (2) is made up of screw (12) and liner (13), shown in Fig. 1 (a), Fig. 1 (b), the existence of liner (13) causes trailing arm attenuation herein, stress concentration, stressed back intensity reduces, be easy to cause the trailing arm fracture, present most of trailing arm all is to break herein.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art and provide a kind of rear suspension assembly of full-floating high-rigidity passenger car, the assembling right alignment of its back axle central siphon to be easy to realize that the strength and stiffness of trailing arm significantly improve, and can also effectively prevent the rear axle beam water inlet tube.
The objective of the invention is to be achieved through the following technical solutions: shown in Fig. 2 (a)～2 (b), rear suspension assembly of full-floating high-rigidity passenger car is by back axle central siphon (9), stabilizer rod (15), torsion bar (10,11), and symmetrical support (8), neck bearing (7), outer bearing (4), trailing arm (2) and trailing arm central siphon (6) are formed, it is characterized in that stabilizer rod (15) places outside the trailing arm central siphon (6), stabilizer rod (15) is connected with the left and right sides trailing arm (2) of back axle central siphon (9) by spline, and is furnished with latching device (12,13,14), back axle central siphon (9), trailing arm central siphon (6) and support (8) fuse by closely cooperating, with two needle bearings (4,7) move and be put in the trailing arm (2).
Because stabilizer rod is external and latching device is arranged, make the stabilizer rod can left and right sides play, really played stabilization; Also avoid the friction of stabilizer rod and trailing arm central siphon, can not produce peculiar noise, improved service life, increased safety.
The outer bearing (4) of the trailing arm central siphon (6) of rear suspension assembly of full-floating high-rigidity passenger car of the present invention adopts the needle bearing that has outer end cap.As Fig. 2 (c), trailing arm (2) is provided with oil hole (16), can middlely refuel, and makes bearing be in lubricating status all the time; Neck bearing (7) and oil sealing are combined, and oil leaks and enters the corrosion of back axle central siphon (9) generation with muddy water in can preventing, thereby reduce the premature wear of bearing.
Stop portion in the middle of the trailing arm of rear suspension assembly of full-floating high-rigidity passenger car of the present invention (2) hangs (A place among Fig. 2 (a)) does not adopt screw, liner, can keep the original thickness of trailing arm like this, and on the trailing arm body, increase T type reinforced rib, the intersection of adjacent regions adopts rounding off to connect (as Fig. 2 (d), Fig. 2 (e)) on trailing arm (2) outline, reduce stress, improved strength and stiffness, adopt before having solved screw and liner to make stress concentration herein, and the problem of fracture takes place.
The invention has the advantages that and to improve the rear suspension assembly durability greatly, further reduce the following right alignment variation in working order of back axle central siphon (9) and trailing arm central siphon (6), avoid car to break away and wear on tyres, reduce inclination angle accuracy error and prenex deviation, thereby improve the car load rideability, increase service life.
