Japan nsk bearings announced the development of new small and lightweight motorcycle brake system with ball screw. In the motorcycle-wire braking system (Brake By Wire System), using the motor of the rotary motion into linear movement, to promote the use of screw-axis hydraulic piston resulting structure. Improved reliability, with the CVT used in motorcycles than 270g ball screw, weight reduction of about 70% to 70g.
The company has developed a thread can not use slot (Thread Groove) shallowing of the structure to prevent thread groove ball into areas outside the lead ball screw lock. Will allow the ball through the back of the original thread slot cycle parts – inserts into the resin material from metal, improved reliability and durability. In addition to the inserts can be realized small-block ball screws, eliminating the need for inserts fixed blocks, also used directly to promote the use of screw-axis structure of the piston, push the piston without the use of putting in order to achieve a small, light quantified. Moreover, in addition to through the realization of a small lightweight, significantly reducing the inertia, he also made use of low-friction ball screw performance, improved responsiveness.
