Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
As shown in fig. 1 and 2, in the present case, the driving axle 2 adopts a design concept of "double-buffer, vertical main and horizontal auxiliary". Specifically, in the vertical direction, the shock absorption pad 4 is used as a component for absorbing energy by impact, and the shock absorption pad 4 is made of an elastic material in the prior art. And in the horizontal direction, the knuckle bearing 5 serves as a shock absorbing member. Further, since the joint bearing 5 can move in the circumferential direction of 360 °, a certain swing displacement can be provided in the vertical direction, and it serves as an auxiliary buffer member for vertical impact. In addition, both the shock pad 4 and the knuckle bearing 5 are parts which are not complex in structure and low in purchase cost, and production and purchase cost on hardware can be effectively controlled.
As shown in fig. 2, one mount 21 is provided on each of the right and left sides of the transaxle 2, i.e., on each of the sides in the vehicle width direction. And the vehicle body 1 includes an upper engaging lug 11. The cushion 4 extends in a vertical direction, and has an upper end directly connected to the upper engaging lug 11 by a fixing member such as a bolt, and a lower end connected to the mounting seat 21. The mounting base 21 is provided with an alignment table 22 protruding upward, the alignment table 22 includes two parts, which are a base part below and a folded part above, the two parts are both cylindrical as a whole, and the folded part has an upward folded design, that is, the cross-sectional area is small at the top and large at the bottom. And a matching alignment hole is arranged at the lower center of the shock pad 4. Such a design, on the one hand, makes the mounting of the shock pad easy and, on the other hand, makes the lower part of the pad with a gradually increasing cross-section, which provides a more stable connection with the shock pad 4. When the vehicle jolts, the impact in the vertical direction is the largest, and the two shock absorption pads 4 are used as energy absorption parts to absorb the vertical impact force between the drive axle 2 and the vehicle body 1 and protect the drive axle 2 and the vehicle body 1.
As shown in fig. 2 and 3, the bridge socket 3 is of a three-stage design, namely a docking plate 31, an extension 32 and a docking ring 33. The central portion of the butt-joint plate 31 is provided with a main positioning spindle 311, and the vehicle body 1 includes a connecting plate 23. The connecting plate 23 and the butt plate 31 are parallel to each other and are connected in a fitting manner. During installation, the main positioning mandrel 311 first enters the mandrel hole in the center of the docking plate 31, and then the engineer uses the auxiliary connector 312 to fixedly connect the connecting plate 23 and the docking plate 31. The design makes the alignment convenient and accurate on one hand, and on the other hand, the matching of the central main positioning core shaft 311 and the peripheral auxiliary connecting pieces 312 makes the connection between the connecting plate 23 and the butt-joint plate 31 more stable. The auxiliary member 312 may be a conventional fixing member such as a bolt in the prior art.
The other end of the bridge joint 3 is connected to the vehicle body 1. Specifically, the body 1 includes two parallel cleats 12, and the docking collar 33 is located in the space between the cleats 12. The spherical region in the middle of the abutment ring 33 is connected with the spherical plain bearing 5. And the pin shaft 6 is connected with the joint bearing 5 through the two clamping plates 12 and the two bushings 7, so that the bridge joint seat 3 is connected with the vehicle body 1. In this section, the horizontal relative movement and a part of the vertical movement between the vehicle body 1 and the bridge adapter 3 are compensated by the spherical joint bearing 5 when the vehicle is subjected to a pitching motion during travel. In addition, when a rough road surface is encountered, unsynchronized displacement between the two drive wheels, for example at different heights at a certain moment, occurs, whereby the drive member 2 is tilted, and this tilting movement is compensated for by the knuckle bearing 5.
As shown in fig. 3 and 4, when the vehicle encounters a bump during traveling, there is relative movement between the vehicle body 1 and the transaxle 2, particularly in the vertical direction. The scheme carries out limit design on the maximum amplitude of the relative movement. Specifically, when the vehicle body 1 is pressed down, the shock pad 4 is compressed, and the deformation stroke of the material of the shock pad 4 determines the pressing-down amplitude of the vehicle body 1, so that the limitation of the amplitude is naturally realized. When the vehicle body 1 is lifted, the distance between the drive axle 2 and the vehicle body 1 in the height direction is increased, and at this time, the lower limit sheet is turned over. As shown in fig. 4, the lower limiting plate 34 is turned over to the upper left and abutted against the abutting plate 13, so as to prevent the vehicle body 1 from further lifting, thereby completing the amplitude limitation and ensuring safety and reliability.
