Detailed description of the invention
The wide variety of automobile suspension system, comprise multi link formula independent suspension system, twist-beam suspension system etc., wherein, in multi link formula independent suspension, suspension system generally includes numerous parts such as top link, lower swing arm and connecting rod, directly cannot be connected with wheel, the scheme that therefore prior art adopts first these parts is connected to wheel stand respectively, then realize the connection with wheel by wheel stand by mandrel; And the parts of twist-beam suspension system are less, therefore do not comprise wheel stand, directly with mandrel, wheel is connected with torsion beam.
For enabling above-mentioned purpose of the present utility model, feature and advantage more become apparent, and are described in detail specific embodiment of the utility model below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of wheel stand, be specially the wheel stand of the multi link formula independent suspension system being applied to multi link formula independent suspension system, particularly automobile axle, with reference to Fig. 1-2, wheel stand has rack body 10, rack body 10 has hub bearing installation portion 10a, and hub bearing installation portion 10a is installed with mandrel 20, hub bearing installation portion 10a and mandrel 20 one-body molded, that is, mandrel 20 is one-body molded with rack body 10.
The mode of two parts is respectively compared to prior art wheel stand and mandrel, this enforcement by mandrel and wheel stand one-body molded, can complete in same procedure, process cost reduces, and the dimensional discrepancy caused due to the difference of technique between different operations both can avoiding; In addition, do not need other assembly process between both, reduce assembly cost.
Wheel stand is connected with support wheel with the hub bearing 30 in wheel nave, and hub bearing 30 is sheathed on outside mandrel 20.
Mandrel 20 comprises interconnective Part I 21 and Part II 22, Part I 21 is connected with rack body 10 and one-body molded, Part II 22 is positioned at Part I 21 one end opposing with rack body 10, the external diameter of Part I 21 is greater than the external diameter of Part II 22, for strengthening the intensity of mandrel 20 and rack body 10 connecting portion.
In the present embodiment, Part I 21 is vertically from the direction near rack body 10 one end to the other end, its external diameter reduces gradually, that is Part I 21 is in round table-like or close to the shape of round platform, the Part I 21 of mandrel 20 can be made like this to have higher intensity, strengthen the support to wheel.Part II 22 is in cylindric, and hub bearing 30 is sheathed on outside Part II 22.
The connecting portion of Part I 21 and Part II 22 has the first chamfering 23.First chamfering 23 can reduce Part I 21 and concentrate with the stress of Part II 22 connecting portion, improves the load-carrying capacity of mandrel 20.Wherein, the first chamfering 23 is rounding, and the radius of rounding is enough large, to obtain the effect reducing stress preferably and concentrate.
Further, Part I 21 has the end face 21a of annular arrangement near Part II 22 one end.When hub bearing 30 be sheathed on mandrel 20 outer time, hub bearing 30 contacts with end face 21a, and end face 21a is for carrying the power applied by hub bearing 30.In the present embodiment, arranging end face 21a is plane, can bear axle pressure more equably like this.
With reference to Fig. 2, between hub bearing 30 with mandrel 20, be connected 40 by lock bolt.Lock bolt 40 comprises head 41 and body 42, body 42 has outside thread 42a, mandrel 20 inside has cylindrical hole 20a, the inwall of cylindrical hole 20a is provided with negative thread 20b, during assembling, body 42 in lock bolt 30 is inserted in cylindrical hole 20a, and the outside thread 42a on body 42 coordinates with the negative thread 20b of mandrel 20, and the head 41 of lock bolt 40 is to being located at hub bearing 30 axially away from one end of the Part I 21 of mandrel 20.
In the present embodiment, opposing with the rack body 10 vertically one end of cylindrical hole 20a inwall has the second chamfering 22a, and the second chamfering 22a is interior chamfering.The insertion of lock bolt can be facilitated like this.
Further, rib (for illustrating in figure) can be set on the surface of rack body 10, for the intensity of reinforced support body 10.
Under vehicle stationary state, wheel stand bears a part of load of vehicle rear; Under motoring condition, wheel stand also needs to bear the impact load passing to suspension from wheel.Therefore, also need to ensure that wheel stand has enough rigidity and intensity.The wheel stand of the present embodiment adopts ironcasting, to obtain larger Rigidity and strength.
With reference to Fig. 1, be distributed with some bolt hole 10b on rack body 10, around hub bearing installation portion 10a, bolt hole 10b is used for installing wheel mud guard as mud guard interface portion.
Continue with reference to Fig. 1 and composition graphs 3, in wheel stand, be also distributed with top link installation portion 31, lower swing arm installation portion 32, rear longitudinal control arm installation portion 33, rear front fast link mounting feature 34, brake caliper hole 35, bumper installation portion 36, wheel speed sensors portion 37 along rack body 10 circumference.Structure, the position at above-mentioned position are all same as the prior art.
Although the utility model discloses as above, the utility model is not defined in this.Any those skilled in the art, not departing from spirit and scope of the present utility model, all can make various changes or modifications, and therefore protection domain of the present utility model should be as the criterion with claim limited range.
