Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further. At this it should be noted that be adapted to assist in for the explanation of these embodiments and understand this utility model, but it is not intended that restriction of the present utility model. As long as just can be mutually combined additionally, technical characteristic involved in each embodiment of this utility model disclosed below does not constitute conflict each other.
As shown in Figures 1 and 2, this torsion beam type rear axle includes rear axle girder 1, stabiliser bar 2, rear axle girder 1 is U-shaped housing, it is symmetrically provided with rear axle curb girder 3 at the two ends of rear axle girder 1, rear-axle tube 4, rear axle damping installation seat 5, support 1, support 27, rear shock absorber mounting pin 8, Rear shock absorber support 9, rear brake mounting bracket 10, rear axle girder 1 two ends are connected with rear axle curb girder 3, the two ends of rear axle curb girder 3 respectively with rear-axle tube 4, rear brake mounting bracket 10 connects, rear axle damping installation seat 5 is connected with rear-axle tube 4, rear axle curb girder 3 region between Rear shock absorber support 9 with rear axle girder 1 and rear brake mounting bracket 10 is connected at the rear axle curb girder 3 near rear brake mounting bracket 10 side, rear shock absorber mounting pin 8 is connected with Rear shock absorber support 9, support 1, support 27 is connected with rear axle girder 1 and rear axle curb girder 3 respectively, stabiliser bar 2 is connected with rear axle girder 1. more specifically, it is that the two sides of U-shaped housing by rear axle girder 1 are connected with rear axle curb girder 3 that rear axle girder 1 is connected with rear axle curb girder 3, the side of the rear axle girder 1 contacted with rear axle curb girder 3 there is arc notch 11, what can be effectively increased rear axle girder 1 and rear axle curb girder 3 is welded to connect area, improve the rigidity of rear axle girder 1 and rear axle curb girder 3, reduce unit and be welded to connect the stress distribution on area, strengthen the bearing capacity of rear axle girder 1 and rear axle curb girder 3, improve the service life of product. stabiliser bar 2 is connected the locking stud 17 of the U-lag beam biside plate referring to stabiliser bar 2 and be connected rear axle girder 1 and connects with rear axle girder 1, and this structure can greatly promote the intensity of rear axle girder 1, rigidity and stability, improves the bearing capacity of whole back axle.As shown in Figure 3, Rear shock absorber support 9 and rear axle curb girder 3 joint face have the flanging 12 of opisthotonos on the face of Rear shock absorber support 9, the contact area of welding of Rear shock absorber support 9 and rear axle curb girder 3 can be effectively increased, improve the bearing capacity of the Rear shock absorber support 9 bonding strength with rear axle curb girder 3 and rigidity, raising product.
