Abstract:
A cable connecting structure of a shift cable assembly is provided to facilitate cable-connection work by easily fitting an eye end to a projection unit after setting up a weighted body and to reduce low vibration transmission ratio by point-contacting a lever with a ball. A cable connecting structure of a shift cable assembly for coupling a shift lever(12) and a shift cable by fitting an eye end(14) of the cable to a projected unit(12a) of the lever has a weighted body(16) hinge-combined to the end of the projection unit. The weighted body is set up to easily fit the eye end and laid to prevent the eye end from being separated after fitting the eye end by pressing the eye end. Plural balls(22) supported elastically by a spring(18) are inserted to an inner peripheral surface of the eye end.
Abstract:
A transmission cable fixing structure is provided to drastically lower a vibration transfer rate to the inside of a vehicle by adopting not a side contact but a spot contact for a contact structure between a transmission cable and a fixing step. A transmission cable fixing structure for reducing vibration comprises a transmission cable(2) connecting a transmission and a gear lever; a first fixing unit(4) anchoring the transmission cable; an intermediate fixing unit(6) installed at an upper side of the first fixing unit and composed of a groove on which balls(12) are placed; and a second fixing unit(10) combined with the intermediate fixing unit to fix the transmission cable. The intermediate fixing unit is round-shaped. The intermediate fixing unit and the second fixing unit are screw-combined(8). The second fixing unit is fixed with the intermediate fixing unit by a circular fixing pin(14).

PURPOSE: A measuring device of error in power transfer between a reduction gear and a differential ring gear is provided to promote efficiency in design of a mechanism and to integrate measured data in a single operator by adopting an additional device for measuring error in power transfer between a reduction gear and a differential ring gear.

The teeth numbers of a reduction gear(32) and a differential ring gear(34) are set, and the drive motor is operated to rotate the input shaft and the output shaft of the transmission. Thereby, the reduction gear and the differential ring gear are rotated. The RPM of the reduction gear is obtained by analysis of encoder signals from the output encoder while the RPM of the other gear is obtained from analysis of encoder signal from a core encoder(40). Error in power transfer is analyzed in the error operator receiving the two kinds of encoder signals. The analyzed data are analyzed again in an FFT(Fast Fourier Transform) analyzer(44) and a phase difference operator(46).
