Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in the utility model, all embodiment that those of ordinary skill in the art obtain under the prerequisite of not paying creative work belong to protection domain of the present utility model.
As shown in Figure 1, driving-shaft assembly can comprise: transmission shaft 1, hanging 2 and hanging support 3, and wherein, transmission shaft 1 is arranged in hanging 2, and hanging 2 is fixedly connected with vehicle body by hanging support 3; Hanging support 3 is provided with multipair project-welding nut 4 along its length, in hanging 2, be provided with pair of bolts hole 12, arbitrary project-welding nut 4 is fixedly installed in bolt hole 12 removably, can adjust the installation dimension of hanging support 3 cooperation of project-welding nut 4 from different in multipair project-welding nut 4 by bolt hole 12, there is stronger commonality thereby make to hang support 3, can be adapted to the installation dimension requirement of different length transmission shaft.
Particularly, can on hanging support 3, multipair project-welding nut 4 be set in advance as required, for example, two pairs, three equities can be set, wherein, the installation dimension number that 3, the support of the corresponding hanging of logarithm of project-welding nut 4 can provide, the logarithm of set project-welding nut 4 is more, and the installation dimension number that 3, support of hanging can provide is also more.Employing is provided with the hanging support 3 of multipair project-welding nut 4, installation site, wheelbase, rear leaf spring parameter or back axle height etc. at car load dynamic assembly change, cause in the situation that propeller shaft length changes, only need to use different project-welding nut 4 instead, and needn't change transmission shaft 1, thereby can reduce installing/dismounting work capacity, effectively reduce the cost of development of product.
As shown in Figures 2 and 3, hanging support 3 can comprise rack body 5 and be positioned at the turnup structure 6 of rack body 5 both sides, specifically above-mentioned project-welding nut 4 can be arranged on turnup structure 6, wherein, turnup structure 6 can be ladder plane structure, this hanging support 3 is simple in structure, easy to install.Preferably, project-welding nut 4 can symmetry arrangement on turnup structure 6, thereby make can to ensure to hang after fixing the whole machine balancing of support 3.
Multiple vehicle body fixed orifices 7 specifically can be set on above-mentioned rack body 5, thereby making to hang 2 can be fixedly connected with vehicle body by vehicle body fixed orifice 7, wherein, the quantity of vehicle body fixed orifice 7 and position specifically can arrange according to body structure, preferably be set to four, wherein two vehicle body fixed orifices 7 are positioned at the midway location of rack body 5, and two other vehicle body fixed orifice 7 is positioned at the boundary position of rack body 5, to be connected and fixed with vehicle body.
The bottom of above-mentioned hanging support 3 is arranged with the brace panel 8 of polylith across turnup structure 6 in parallel, and can be provided with bolt hole 12 on the brace panel 8 of project-welding nut 4 correspondence positions.Can improve the bulk strength of hanging support 3 by brace panel 8 is set, bolt hole 12 is set on the brace panel 8 of project-welding nut 4 correspondence positions can be with boltsly easily fixed with hanging 2.
In actual use, can adopt different transmission shaft 1 according to different vehicles, for example, commercial vehicle/comm..vehicle can adopt Cardon universal joint transmission shaft 1.The layout of transmission shaft need to meet certain requirement, for example, the single-unit length of transmission shaft can not be long, critical speed need to meet the requirement of the car load speed of a motor vehicle, therefore, transmission shaft can adopt multi-section structure, is wherein connected and adopts universal-joint to be connected between two joints, preferably the end of transmission shaft 1 first segment is arranged in hanging 2.
As shown in Figure 4, hanging 2 can comprise: bearing 9 and rigid cage 10, and wherein, bearing 9 is socketed on transmission shaft 1, and rigid cage 10 is fixed on the outside of bearing 9.Particularly, rigid cage 10 can comprise annular 13He You socket part, socket part 13 installation portion 14 of a pair of projection forming that stretches out.For easy for installation, the bolt hole 12 in hanging 2 can be separately positioned on two installation portions 13, and bolt hole 12 can be set to waist shaped hole, thereby can allow the existence of certain installation error, reduce the requirement to parts precision.In addition, waist shaped hole is set to the direction parallel with transmission shaft 1, can also select after specific project-welding nut 4, in waist shaped hole length range, the installation dimension of hanging support 3 is finely tuned.
Because transmission shaft 1 is under the conventional operating mode of car load, the angle of hanging between attachment face and the transmission shaft 1 at 2 places is less than specific angle, for example 1 °, therefore, above-mentioned hanging 2 can also comprise the resilient rubbber cushion 11 that is arranged on bearing 9 and transmission shaft 1 connection location, thus effective vibration damping, prevent that transmission shaft 1 and other parts of car load from resonating, in addition, can also finely tune the angle of hanging between 2 attachment face and transmission shaft 1, thereby can meet corresponding angle requirement.
