Brake recovery silent wheel part structure

摘要

[PROBLEMS] When the action of the braking mechanism in various wheels to control the direction of rotation, there is provided a brake recovery unvoiced wheelset structure capable of preventing the generation of noise. A wheel frame part 1 and the rotary unit 2 is constituted by a direction limiting the brake unit 3 and the pressing portion 4, it said wheel frame portion is a wheel entity is coupled to a rotating part, wheel seat 11 and the pivot 12 and made from the wheel 13, said wheel seat may pivot is pivotally mounted, said rotating unit is assembled to the wheel seat, inside the fitting block 21 is provided in said direction only braking portion is installed in the wheel seat , mainly 31 and the brake block 32, consists of a braking direction limiting block 33 and the elastic member, a pressing portion, by applying a force to the brake block and the brake direction limiting block to actuate the brakes and control direction limitation action, also by the elastic member, the pressing body can recover, the pressing portion is pivotally attached to the pivot of the wheel frame portion, has a pressing body mainly, in pressing body, sound deadening material is installed, the pressing body is recovered In the process, silent effect can be obtained. .BACKGROUND
