The longitudinal arm structure is characterized in that a longitudinal arm main body is arranged in a V-shaped manner, a rubber bushing assembly is arranged at one end of the longitudinal arm main body, one end of the longitudinal arm main body is connected with an automobile body module by a connecting bolt in the rubber bushing assembly, and the other end of the longitudinal arm main body is connected with a steering knuckle by the connecting bolt. The longitudinal arm structure model has the advantages of high reliability, light weight and good comprehensive performance.
Description
Technical field
The utility model belongs to the automotive suspension field, the trailing arm structure in the automotive suspension of more specifically saying so.
Background technology
In the patent No. is in the utility model patent document of CN200420021139.6, a kind of back trailing arm assembly is disclosed, its keystone configuration is provided in a side of anterior bend loss and is located at the straight length at rear portion, also comprises back trailing arm support, back sprung shock-strut support, axle head connecting panel, back upper suspension arm support, back lower controlling arm support, lining sleeve pipe and lining on the structure; Back trailing arm support is connected to the relative both sides of the straight length of trailing arm afterwards with back sprung shock-strut support, the axle head connecting panel is connected the opposite side of back trailing arm support, back upper suspension arm support and back lower controlling arm support are separately positioned on the axle head connecting panel, the lining sleeve pipe is connected the forefront of the bend loss of back trailing arm, lining is arranged in the lining sleeve pipe, this version can realize that back trailing arm assembly passes through the outerplanar metalworking of axle head connecting panel, can guarantee the positional parameter of wheel well, avoid traditional swing arm body designing, difficulty on making and processing, but its shortcoming is a complex structure.
In present many connecting rods rear suspension structure, common trailing arm assembly is when playing directional tagging, and the degree of freedom to other direction has produced too much constraint again.At work, because its stressing conditions harshness, so stock size is bigger, so that the weight increase, required arrangement space strengthens, and vehicle performance is degenerated.
In existing multi-link lever suspension fork, trailing arm version is various, but can not make weight usually, cost, stiffness, distortion amount of deflection, and the problems such as fatigue life that the internal stress problem causes are to unified better solution.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology deficiency, provide a kind of and can make weight, cost, distortion amount of deflection, and the problems such as fatigue life that cause of internal stress problem trailing arm structure in the automotive suspension of unified better solution.
The utility model technical solution problem adopts following technical scheme:
The characteristics of trailing arm structure are the V-shaped trailing arm bodies that is provided with in the utility model automotive suspension, trailing arm body one end is provided with the rubber bush assembly, in the rubber bush assembly, be provided for the tie bolt that is connected with the vehicle body module, the through hole that is connected with steering swivel in the other end setting of trailing arm body.
Constructional feature of the present utility model also is:
The bending angle of the trailing arm body of described V-shaped setting is 130 °-160 °, and the trailing arm body adopts sheet stamping member.
On the trailing arm body of described V-shaped setting, according to shape setting " V " the shape loss of weight groove that matches with it.
The urceolus that the rubber bush assembly is set is suspension ring, is lining in the tube, and central authorities are connecting panel, and described tie bolt is fixedly installed on the two ends of connecting panel; One end of trailing arm body is fixedly welded on the periphery of suspension ring.
Compared with the prior art, the utility model beneficial effect is embodied in
1, in the process that is suspended in motion in the utility model,, can provide longitudinal rigidity by the anisotropic properties of rubber bush, simultaneously again can be for laterally providing than high camber.
2, the trailing arm body in the utility model can adopt sheet stamping member, and drawing is easily manufactured; Its " V " shape structure can laterally provide than deep camber for suspension again for suspension provides very big longitudinal rigidity in the process of suspension motion simultaneously.
3, the utility model is offered the loss of weight groove on the trailing arm body, when realizing loss of weight can so that the trailing arm assembly in the course of the work stress rationally distribute, improve the intensity of trailing arm assembly indirectly.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model rubber bush assembly decomposition texture scheme drawing.
Fig. 3 is the utility model rubber bush assembly cross-sectional schematic.
Number in the figure: 1 rubber bush assembly, 11 suspension ring, 12 linings, 13 connecting panels, 14 tie bolts, 2 loss of weight grooves, 3 trailing arm bodies.
Below pass through the specific embodiment, and in conjunction with the accompanying drawings the utility model is further described.
The specific embodiment
Referring to Fig. 1, the V-shaped trailing arm body 3 that is provided with, the bending angle of trailing arm body 3 is set to 130 °-160 °, trailing arm body 3 one ends are provided with rubber bush assembly 1, link to each other with the vehicle body module with the tie bolt in the rubber bush assembly 1, the other end of trailing arm body 3 links to each other with steering swivel by bolt.
Trailing arm body 3 adopts sheet stamping member, on the trailing arm body 3 of V-shaped setting, according to shape setting " V " the shape loss of weight groove 2 that matches with it.
Referring to Fig. 2, Fig. 3, the urceolus of rubber bush assembly 1 is suspension ring 11, is lining 12 in the tube, and central authorities are connecting panel 13, are tie bolt 14 at the two ends of connecting panel 13; One end of trailing arm body 3 is fixedly welded on the periphery of suspension ring 11, and the tie bolt 14 in the rubber bush assembly 1 is used for linking to each other with the vehicle body module; The other end of trailing arm body 3 links to each other with steering swivel by four bolts.
In the process of motion, " V " shape trailing arm body and rubber bush assembly simultaneously again can be for laterally providing than deep camber jointly for suspension provides very big longitudinal rigidity; The respective outer side edges of groove can make trailing arm assembly stress in the process of work rationally distribute the intensity of indirect raising trailing arm assembly.
