Abstract
A shift manipulating apparatus for an automatic transmission is disclosed that transmits manipulating force from a shift lever to a manual valve to position the spool of a manual valve at identical places in ranges P and N. The apparatus comprises a shift lever to receive shift range selection manipulating force of a driver; a manual valve to control oil pressure of the automatic transmission; and a linkage unit for connecting the shift lever and the spool of the manual valve to enable the spool to identically form an interconnection state of ports according to pivot of the shift lever in ranges P and N.
Claims10
A shift manipulating apparatus for an automatic transmission, including at least drive (D), park (P) and neutral (N) gear ranges, comprising:
- a shift lever to receive shift range selection manipulating force from a driver;
- a manual valve to control oil pressure of the automatic transmission;
- and
- linkage means for connecting the shift lever and a spool of the manual valve to enable the spool of the manual valve to identically form an interconnection of ports in the manual valve for both ranges P and N.
A shift manipulating apparatus for an automatic transmission, wherein the transmission includes at least drive, reverse, neutral and park gear ranges, said apparatus comprising a gear shift mechanism cooperating with a manual valve, wherein;
- the manual valve includes identical hydraulic port positions for both the neutral and park gear ranges, and
- the gear shift mechanism comprises:
- a shift lever;
- a first linkage member having a first end operatively linked to the shift lever, and a second end;
- a second linkage member having a first end operatively linked to the first linkage member second end at a second connection point, and a second end;
- and
- a third linkage member having a first end operatively linked to the second linkage member second end at a first connection point, and a second end operatively linked to the manual valve;
- wherein said first connection point is guided to be equally spaced from the manual valve in both the neutral and park gear ranges.
