An end face away from input gear 4 and two end faces keeping off the close input gear 4 of the input disc 20a of electronic stylus pin bonding apparatus of the buffer disc 20j of the electronic stylus pin bonding apparatus of two gears remain certain gap.
The working principle that electronic stylus pin bonding apparatus formula two keeps off electric car automatic speed transmission is further illustrated below in conjunction with embodiment:
The external cylindrical surface of the input disc 10a of the electronic stylus pin bonding apparatus of a gear fixedly mounts electric slip ring, is controlled energising and the power-off of the second electromagnetic coil 10f of the electronic stylus pin bonding apparatus of a first electromagnetic coil 10c and gear of the electronic stylus pin bonding apparatus of a gear by electric slip ring and outer brush; Equally, the external cylindrical surface of the input disc 20a of the electronic stylus pin bonding apparatus of two gears fixedly mounts electric slip ring, is controlled energising and the power-off of the second electromagnetic coil 20f of the electronic stylus pin bonding apparatus of the first electromagnetic coil 20c and two gear of the electronic stylus pin bonding apparatus of two gears by electric slip ring and outer brush.
During one gear transmission, second electromagnetic coil 10f of the electronic stylus pin bonding apparatus of a first electromagnetic coil 10c and gear of the electronic stylus pin bonding apparatus of one gear is energized, the magnetic force that second electromagnetic coil 10f of the electronic stylus pin bonding apparatus of a first electromagnetic coil 10c and gear of the electronic stylus pin bonding apparatus of one gear produces makes the second electronic stylus pin 10g of the electronic stylus pin bonding apparatus of the first electronic stylus pin 10d of an a gear electronic stylus pin bonding apparatus and gear overcome the elastic force effect of return spring and move to a direction keeping off the output disc 10h of electronic stylus pin bonding apparatus, second electronic stylus pin 10g of the electronic stylus pin bonding apparatus of a first electronic stylus pin 10d and gear of the electronic stylus pin bonding apparatus of one gear slips into one end of the arc-shaped ring groove 10m of the electronic stylus pin bonding apparatus of a gear under rotation status, thus drive the buffer disc 10j synchronous rotary of the electronic stylus pin bonding apparatus of a gear, simultaneously because the flank of the outer double wedge 10k of the electronic stylus pin bonding apparatus of a gear is resisted against on a pressure-bearing side of the rubber spring element 10n of the electronic stylus pin bonding apparatus of a gear, and another pressure-bearing side of the rubber spring element 10n of the electronic stylus pin bonding apparatus of a gear is resisted against on the flank of the interior double wedge 10i of a gear electronic stylus pin bonding apparatus, therefore, the buffer disc 10j and one of the electronic stylus pin bonding apparatus of one gear keeps off the output disc 10h synchronous rotary of electronic stylus pin bonding apparatus, thus make the input disc 10a and of a gear electronic stylus pin bonding apparatus keep off the output disc 10h Synchronous Transmission of electronic stylus pin bonding apparatus.
During two gear transmissions, second electromagnetic coil 20f of the electronic stylus pin bonding apparatus of the first electromagnetic coil 20c and two gear of the electronic stylus pin bonding apparatus of two gears is energized, the magnetic force that second electromagnetic coil 20f of the electronic stylus pin bonding apparatus of the first electromagnetic coil 20c and two gear of the electronic stylus pin bonding apparatus of two gears produces makes the second electronic stylus pin 20g of the electronic stylus pin bonding apparatus of the first electronic stylus pin 20d of two gears electronic stylus pin bonding apparatus and two gear overcome the elastic force effect of return spring and move to two directions keeping off the output disc 20h of electronic stylus pin bonding apparatus, second electronic stylus pin 20g of the electronic stylus pin bonding apparatus of the first electronic stylus pin 20d and two gear of the electronic stylus pin bonding apparatus of two gears slips into one end of the arc-shaped ring groove 20m of the electronic stylus pin bonding apparatus of two gears under rotation status, thus drive the buffer disc 20j synchronous rotary of the electronic stylus pin bonding apparatus of two gears, simultaneously because the flank of the outer double wedge 20k of the electronic stylus pin bonding apparatus of two gears is resisted against on a pressure-bearing side of the rubber spring element 20n of the electronic stylus pin bonding apparatus of two gears, and another pressure-bearing side of the rubber spring element 20n of the electronic stylus pin bonding apparatus of two gears is resisted against on the flank of the interior double wedge 20i of two gears electronic stylus pin bonding apparatus, therefore, the buffer disc 20j and two of the electronic stylus pin bonding apparatus of two gears keeps off the output disc 20h synchronous rotary of electronic stylus pin bonding apparatus, thus make the input disc 20a and two of two gears electronic stylus pin bonding apparatus keep off the output disc 20h Synchronous Transmission of electronic stylus pin bonding apparatus.
