Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.

As shown in fig. 1 to 3, the embodiment provides a novel brake, including wheel hub 1, ring gear connecting axle 4 and ABS ring gear 8, wheel hub 1 is last to be provided with rather than coaxial spliced pole 15, spliced pole 15 has set gradually mounting groove 2 and mounting hole 3 along its axial, the diameter sudden change in both ends of ring gear connecting axle 4 forms first boss 5 and second boss 6 respectively, ring gear connecting axle 4 is provided with through-hole 7 that runs through its both ends along its axial, 8 covers of ABS ring gear are established first boss 5 periphery, second boss 6 corresponds and stretches into in the mounting groove 2, and with 2 interference fit of mounting groove, the fastener is through passing in proper order ABS ring gear 8, through-hole 7 with mounting groove 2, and stretch into in the mounting hole 3.
