摘要:
A movable case for making a steerable wheel steerable is slidably held in an axle case, a tie rod for a steering operation is made telescopically movable, and the movable case and the tie rod are arranged to be locked at an extended or retracted position. At the time of effecting tread adjustment, a steering wheel is rotated to its extreme end, and the vehicle is made to run with the movable case made slidable, which allows the movable case to slide outward through the axle case, permitting tread adjustment to be carried out automatically.

摘要:
A transparent polyester-ester amide having a permanently antistatic property is obtained by copolymerizing (a) an aminocarboxylic acid, a lactam, or a salt derived from a diamine and a dicarboxylic acid; (b) a diol of the formula: ##STR1## wherein R.sup.1 and R.sup.2 are an ethylene oxide or propylene oxide group, Y is covalent bond, alkylene, alkylidene, cycloalkylidene, arylalkylidene, O, SO, SO.sub.2, CO, S, CF.sub.2, C(CF.sub.3).sub.2 or NH, X is H, alkyl, halogen, sulfonic acid or salt thereof, l is 0 or an integer of 1-4, and m and n an integer of 1-15; (c) a poly(alkylene oxide)glycol or a diol of the formula:HO--R.sup.3 --OH (IV)wherein R.sup.3 is alkylene, alkylidene, cycloalkylidene or arylalkylidene; and (d) a dicarboxylic acid; wherein the content of the polyether-ester units is 10 to 90 wt. %. The polyether-ester amide is used preferably as a blend thereof with a graft copolymerization product formed by graft-polymerizing (a) a rubbery polymer with (b) a monomer mixture of a methacrylic or acrylic acid ester, an aromatic vinyl monomer and an optional vinyl cyanide monomer, this product having a refractive index approximately similar to that of the polyether-ester amide.
摘要:
A tractor change speed apparatus includes a manual change speed device having a combination of gear trains mounted on first and second parallel shafts and driving a change speed output shaft at various speeds. A backward and forward drive switching device is cooperable with the main change speed device for producing forward and backward drives in an equal number of speeds, wherein the forward drive is transmitted through the first shaft and the backward drive is transmitted through the second shaft. A group of gears for returning reverse drive to a forward drive transmission shaft is thereby omitted. Consequently, the backward and forward drive switching device and the entire change speed apparatus has a reduced longitudinal length.

摘要:
An apparatus for transmitting drive from an engine through a main clutch to front or rear wheels of a working vehicle, includes a main change speed device and an auxiliary change speed device. The main change speed device includes a first shaft, an intermediate shaft, and a main shaft disposed in an end-to-end relationship with the first shaft and extending parallel to the intermediate shaft. The auxiliary change speed device includes an output shaft axially overlapping and extending parallel to the main shaft, and a creep shaft extending parallel to the output shaft. The intermediate shaft supports a first shift clutch for selectively providing a first and a second speed stages. The main shaft supports a second shift clutch for selectively providing a third and a fourth speed stages. The output shaft supports a third shift clutch for selectively providing a high speed state and an ultralow speed state, and a fourth shift clutch for selectively providing a low speed state and a backward drive state.
摘要:
A change speed apparatus for a tractor includes a main change speed device (24) having a combination of gear trains mounted on a first shaft and a second shaft extending parallel to each other, for driving a change speed output shaft (58) at a plurality of speeds, and a backward and forward drive switching device (21) cooperable with the main change speed device (24) to produces forward drive and backward drive in an equal number of speeds. Between the main change speed device (24) and the backward and forward drive switching device (21), the forward drive is transmitted through the first shaft (45) and the backward drive is transmitted through the second shaft (44). With this construction, a group of gears for returning reversed drive to a forward drive transmission shaft is omitted from the backward and forward drive switching device (21). Consequently, the backward and forward drive switching device has a reduced fore and aft length, and thus the entire change speed apparatus also has a reduced fore and aft length.
