NTN develops planetary roller threaded electric brake transmission equipment

NTN has developed a new generation of automotive brake equipment that is lightweight, small and durable, and has a planetary roller-threaded electric x-vehicle transmission device; it will be opened at the 40th Tokyo Motor Show (Volkswagen Open) Day: October 27th - November 11th, 2007) See the presentation. Its layout is similar to that of planetary gear reduction; but the center is not the sun gear; it is the cylindrical sun roller. Planetary gear and ring gear In the azimuth; not placed in the bearing; but removed the threaded sun roller and the ring roller.
The sun roller is driven by a motor. The planetary roller is transformed by conductive traction. The bracket is also transformed. The planetary roller is fitted with the thread of the ring roller; thus the carriage is pushed out along the axis. Place the x-car block in front of the direction; thereby propelling the x-vehicle. The rotation of the planetary rollers is opposite to the direction of rotation of the revolution; the difference between the speeds of the two is the speed of the carriage. Thus; from the sun roller to the bracket The reduction ratio has become enormous.
As one of the wire control (Steer-By-Wire; vehicle electrification) skills; the transmission equipment using the electric x car must have the structure of converting the rotary motion of the motor into the thrust of the x-car to drive the x-wheel. The direct-acting stroke is necessary. It is lacking. Before that; the Ball Screw method and the combination of the roller and the wedge iron were presented; however, because of the need for other equipment to slow down the organization; The layout becomes complicated. The organization of this development can be used together as a tissue that transforms the rotation into a direct motion and a deceleration structure; thus, miniaturization can be achieved.

ATP (NATIONAL STANDARD)

PRODUCT NAME: ATP Aluminum Dihydrogen Tripolyphosphate

PRODUCT TYPE: Anti-corrosion Pigment

PRODUCT APPEARANCE: White Powder

CHEMICAL CLASS:AlH₂P₃O₁₀ Â· 2H₂O

CAS No．: 13939-25-8

PRODUCT APPLICATION: Aluminum tripolyphosphate, as a new generation of white antirust pigment made by Xinsheng Chemical, is the ideal substitute of toxic antirust pigments containing lead or chrome. It turns out through practical applications and test results by over 100 well-known coating material producers or researching institutes at home and abroad since it came onto the market in 1986, that this product is superior to such antirust pigments as lead red, zinc chrome yellow and Zinc Phosphate in rust prevention and practicality.

Modified Aluminum Tripolyphosphate is suitable for production of water paint while Aluminum Tripolyphosphate is suitable for oil paint. ATP is used in high-temperature resistant paints, wear resistant brake pads and Wheel slices.
