The side wall of the push plate 714 is a cylindrical curved surface protruding outwards along the radial direction of the cylinder 722, the most protruding part of the push plate 714 starts to press the brake 8, and the brake 8 presses the wheel hub to realize braking.
When the telescopic member 713 and the pushing plate 714 rotate to a position where the diameter of the cylinder 722 is smaller, the inner wall of the cylinder 722 presses the pushing plate 714, the pushing plate 714 starts to press the second gasket 7135, the second gasket 7135 pushes the telescopic rod 7134 to slide towards the telescopic tube 7131 along the axial direction of the telescopic tube 7131, and the telescopic member 713 contracts. Second gasket 7135 and the gliding in-process of telescopic link 7134, when second gasket 7135 extrudes first spring 7133, first spring 7133 can play the buffering supporting role to second gasket 7135, avoids second gasket 7135 directly to strike on first gasket 7132.
When the pushing plate 714 rotates to the position of the operation hole 725, the pushing plate 714 is extruded on the upper surface of the extruding block 831, the upper surface of the extruding block 831 is a concave curved surface, the side wall of the pushing plate 714 is a curved surface protruding outwards, and the upper surfaces of the pushing plate 714 and the extruding block 831 are matched just, so that accurate extrusion of the pushing plate 714 on the extruding block 831 is ensured, and the situation that the position of an applied acting force is inaccurate is avoided. The upper surfaces of the pushing plate 714 and the squeezing block 831 are matched just, so that the squeezing force of the pushing plate 714 can be effectively transmitted to the squeezing block 831. The squeezing block 831 rotates under the squeezing of the pushing plate 714 and drives the inner squeezing plate 84 to rotate, the squeezing plate 84 protrudes outwards from the outer squeezing plate 81 and begins to squeeze the hub of the wheel, and braking is achieved.
When the friction member 842 and the rubber layer 843 contact the hub of the wheel, the friction member 842 and the rubber layer 843 may be pressed against the hub of the wheel due to the inertia of the wheel to generate a friction force and a pressing force. When the friction member 842 is subjected to a transverse extrusion acting force, the extrusion force is transmitted to the rubber rod 8424, the rubber rod 8424 transmits the extrusion force to the load carrying strip 8423, and the load carrying strip 8423 is made of steel, so that the bearing capacity is high, and the stability of the overall structure of the friction member 842 is ensured. The rubber rod 8424 is made of a rubber material, and can deform when being greatly extruded, so that a buffering effect is achieved.
After installation, a certain gap exists between the load strip 8423 and the body 8421, the body 8421 is made of rubber materials, certain deformation can be generated after the body 8421 is extruded, a certain space is reserved for the deformation of the body 8421 just by the gap left during installation, the damage caused by transverse direct contact extrusion of the body 8421 and the load strip 8423 is avoided, and a buffering effect is achieved.
The baffle 8428 is rectangular and is made of a rubber material. During braking, firstly, the friction roller 8427 directly contacts with the hub of a braked wheel, the friction roller 8427 is made of rubber materials, and the surface of the friction roller 8427 is provided with spiral grooves. After the friction roller 8427 contacts the hub, the wheel continues to move under the action of inertia, and at the moment, the friction roller 8427 rotates under the transverse acting force of the hub, so that friction or impact damage caused by direct hard extrusion contact is avoided. Meanwhile, the spiral grooves on the surface of the friction roller 8427 cause the surface to be unsmooth, so that the friction force is further increased when the friction roller contacts with a wheel hub, and the braking capacity is improved.
