As further improvement of the utility model, describedly take turns the cannula type connection mode that limit structure and contiguous block are free-running fit.
The beneficial effects of the utility model are:
1, adopt shaft tube type connection structure, centre is left larger space and is beneficial to car load chassis layout;
2, adopt cannula type wheel limit, be convenient to the relative position on regulating wheel limit, thus in the time that needs are developed this type of follow-up bridge of new wheelspan, without redesign, only need in the time that being installed, whole bridge adjust position, respective wheel limit, simple and easy convenient;
3, whole bridge installs ABS structure additional and realizes wheel speed signal output function, has realized wheel speed sensing function, and improves whole bridge economy.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, this cannula type follow-up bridge is symmetrical structure to the structure of a kind of cannula type follow-up bridge of the utility model, comprises wheel limit structure 1, contiguous block 2 and central siphon 4.Wheel limit structure 1 is connected by contiguous block 2 with central siphon 4, and contiguous block 2 comprises knock hole 12 and lower knock hole 13, and the perforate direction of upper knock hole 12 and lower knock hole 13 is consistent.Central siphon 4 connects left and right two parts assembly.The utility model also comprises end cap 5, with the hole at four end caps, 5 disk wheel limit structures and central siphon two ends.The utility model also comprises spring block 3, and spring block 3 is welded in the bottom of contiguous block 2, is arranged at contiguous block 2 one end near lower knock hole 13.Wheel limit structure 1 is drum-type wheel limit structure, drum-type wheel limit structure comprises abs sensor 11, support 6, drum brake mechanism 8, gear ring 9 and axle tube flange 10, the contact of abs sensor 11 is through the centre hole of the support 6 with ABS lining, realize and contacting with gear ring 9, support 6 is fixed on axle tube flange 10.Upper knock hole 12 is less than the length of lower knock hole 13 along perforate direction along the length of perforate direction.The cannula type connection mode that wheel limit structure 1 and contiguous block 2 are free-running fit.As shown in figure 11, its right elevation as shown in figure 12 for the inner structure of wheel limit structure.
