Detailed description of the invention
In order to be better understood by the purpose of this utility model, structure and function, below in conjunction with accompanying drawing, one of the present utility model breakaway-element jack shaft and automobile can be done further detailed description.
It is carry out with reference to conventional vehicle axis system that orientation in this utility model describes.Vehicle axis system is used to describe the special moving coordinate system of motor racing, its initial point overlaps with vehicle centroid, and when vehicle remains static on level road, X-axis is parallel to ground and points to rear view of vehicle, Z axis is pointed up by vehicle centroid, and Y-axis is pointed to copilot direction by driver.Wherein, the left and right orientation in this utility model refers to the Y direction along vehicle axis system, and left bit is to for Y-axis negative direction, and right bit corresponds to Y-axis positive direction；Forward and backward orientation refers to the X-direction along vehicle axis system, and front orientation is to for X-axis negative direction, and back side corresponds to X-axis positive direction；Upper and lower orientation refers to the Z-direction along vehicle axis system, and upper position is to for Z axis positive direction, and lower orientation corresponds to Z axis negative direction.
As shown in Figures 2 to 6, of the present utility model the first semiaxis 1 and the second semiaxis 2 can be included by breakaway-element jack shaft.Wherein, one end of first semiaxis 1 is wheel hub link 11, the other end is semiaxis link 12, one end of second semiaxis 2 is decelerator installation end 21, the other end is semiaxis link 22, semiaxis link 12 on first semiaxis 1 and the semiaxis link 22 on the second semiaxis 2 can be connected with each other, to form jack shaft.Thus, of the present utility model can breakaway-element jack shaft avoid dismounting power assembly time need to pull down jack shaft completely, enhance the maintainability of dynamical system and jack shaft.
Further, the axial length of the first semiaxis 1 is preferably greater than the axial length of the second semiaxis 2.That is, as it is shown on figure 3, the first semiaxis 1 length in the lateral direction is more than the second semiaxis 2 length in the lateral direction, the link position of the first semiaxis 1 and the second semiaxis 2 is closer to dynamical system.Thus, when keeping in repair power assembly, can first by the connection disassembling between the first semiaxis 1 and the second semiaxis 2, the first semiaxis 1 (major axis) is made to separate with power assembly, then just can directly power assembly be pulled down from vehicle body, avoid rim brake and drive the entirety of axle to disassemble, enhancing the maintainability of dynamical system.
Further, semiaxis link 12 place on the first semiaxis 1 is respectively arranged with ring flange with semiaxis link 12 place on the second semiaxis 2, and the ring flange 13 on the first semiaxis 1 can pass through to be connected assembly with the ring flange 23 on the second semiaxis 2 and be fixedly linked.Wherein, connection assembly in the present embodiment is connecting bolt 31 and attaching nut 32, ring flange on first semiaxis 1 and the second semiaxis 2 is respectively formed with at least one connecting hole 33, the connecting hole 33 that connecting bolt 31 may pass through on ring flange is connected with attaching nut 32, the first semiaxis 1 and the second semiaxis 2 to be linked together.It is moreover observed that, this utility model is not limited to ring flange form recited above for the type of attachment between the first semiaxis 1 and the second semiaxis 2, the structure being arbitrarily capable of linkage function all may be used in this utility model.
Further, the connecting end surface of the ring flange 13 on the first semiaxis 1 is formed with alignment pin 34, the connecting end surface of the ring flange 23 on the second semiaxis 2 is formed hole, location (not shown)；And/or the connecting end surface of the ring flange 13 that first on semiaxis 1 is formed hole, location (not shown), the connecting end surface of the ring flange 23 on the second semiaxis 2 is formed with alignment pin 34.Thus, the alignment pin 34 on the connecting end surface of one of them ring flange can be plugged in the hole, location on the connecting end surface of another ring flange, to ensure the connection precision of ring flange, it is prevented that connecting bolt deformation produces to loosen.
Further, the first semiaxis 1 and the second semiaxis 2 can be one-body molded (such as one forging molding) with the ring flange at respective semiaxis link place respectively, to ensure the fastness of jack shaft.It is moreover observed that, the first semiaxis 1 in this utility model and the ring flange on the second semiaxis 2 can adopt the common structure of existing ring flange, such as circular, oval, star and various reinforcements etc., in this utility model, this do not limited.
Of the present utility model can breakaway-element jack shaft avoid dismounting power assembly time jack shaft need to be pulled down completely, enhance the maintainability of dynamical system and jack shaft.
By specific embodiment, this utility model is further described above; although it is understood that; here concrete description; should not be construed as the restriction to spirit and scope of the present utility model; the various amendments that above-described embodiment is made by one of ordinary skilled in the art after reading this specification, broadly fall into the scope that this utility model is protected.
