  • Patent number: 6857335
    Abstract: A manipulation lever can be manipulated to select a first mode for automatically changing the drive range of an automatic transmission or a second mode for changing the drive range by manually manipulating the manipulation lever. The manipulation lever is shifted between the first mode in which a control lever moves mechanically with the manipulation lever and the second mode in which the control lever does not move with the manipulation lever. A first guide portion guides the manipulation lever and a second guide portion guides the clutch lever. When the manipulation lever is arranged at the drive position, the first and second guide portions permit the manipulation lever to be disengaged from the clutch lever. When the manipulation lever is arranged at positions other than the drive position, the first and second guide portions keep the manipulation lever to be engaged with the clutch lever.

  • Publication number: 20040244523
    Abstract: A hydraulic servo assembly includes a piston slidably disposed within a housing and a pin extending from the piston. The pin is interconnected with a servo link rod of the ETRS system. A port enables inlet of hydraulic fluid to induce movement of the piston and the pin from a first position to a second position to pull the servo link rod thereby shifting the transmission range to the out-of-park position. When in the first position the pin biases a forward-reverse enable (FRE) valve of the ETRS system in a first position. When in the second position a bias force of the pin is relieved from the FRE valve enabling the FRE valve to shift to a second position.

  • Publication number: 20040118236
    Abstract: The invention provides a gate type shift lever apparatus in which a solenoid type shift lock mechanism is built at a position engaging with a shift lever (3) of a position P. This shift lock mechanism is constituted by a solenoid (12) which is turned on at a time when a brake pedal is stepped on, a slider (11) which is closely contacted with the solenoid (12) by a spring (14) at a normal time, and a shift lock plate (13) which is pivoted onto the slider (11). The shift lock plate (13) is oscillated along with a selecting operation of a shift lever (3). When a select operation of the shift lever (3) is carried out in the case that the brake pedal is stepped on and the solenoid (12) is in an on state, the slider (11) is adsorbed by the slider (12) so as to stay at a fixed position, so that only the shift lock plate (13) oscillates so as to move the shift lever (3) from the position (P).

The shift control rod is secured to the retainer by clip portions formed thereon in a manner such that a final assembly threaded member can be secured on the fastener member of the shift linkage to complete the shift control assembly. The assembly method involves providing a shift link with a fastener secured thereto, assembling a retainer on the shift link, assembling a control rod on the retainer, and securing the assembly together with a fastener member securely engaging the fastener secured to the shift link.

  • Patent number: 6615941
    Abstract: An electric wheelchair simultaneous gear change structure, comprising a structure that includes two separate oscillating plates, oscillating plate one and oscillating plate two, as well as hinge connectors placed on either end of the central connecting shaft connecting oscillating plate one and oscillating plate two. One end of oscillating plate one is a hinge connection connecting to an outer connecting rod, and the other end of the outer connecting rod is connected by a hinge connector to the gearshifts, so that when a pulling motion is made on the gearshifts it acts to pull on the oscillating plate on the outer connecting rod, so that oscillating rod two on the central connecting rod is made to move simultaneously, and in this way two engine boxes are acted on simultaneously.

  • Patent number: 6575049
    Abstract: A shift lever device in which a shift lever lock mechanism is not released inadvertently, and improper operation is prevented. In the shift lever device, a lock plate, which impedes movement of a detent rod, is covered by a cavity portion of a shift lever. These internal devices are covered by a cover box and a detent plate. In a P shift position, a gap formed by, on the one hand, the cover box and the detent plate, and, on the other hand, the shift lever and the cavity portion thereof, is a labyrinthine structure which is stepped along a horizontal direction. Accordingly, improper operation can be further prevented.

  • Patent number: 6557599
    Abstract: A wood planing machine includes a first drive transmission member transmitting a rotating force of a cutting member to a first transmission shaft with two gears mounted thereon. Two gears are splined on a second transmission shaft and are movable along an axis of the shaft such that one gear meshes with a respective one of the gears on the first transmission shaft so as to result in two reduction drives of the second transmission shaft. A second drive transmission member transmits one of the reduction drives to a feed-in rolling member. An actuating member is rotated with a rotating force which is transformed by a cam member into a translation force to move the gears on the second transmission shaft.
