摘要:
A planetary gear transmission typically for use on automobiles has first, second, and third planetary gear trains arranged coaxially with each other and each having elements including a sun gear, a carrier, and a ring gear. Two of the elements of each of the first, second, and third planetary gear trains are directly or disengageably coupled to elements of the other planetary gear trains between input and output members. The elements of the first, second, and third planetary gear trains are corotatably coupled into first, second, third, fourth, and fifth rotational members the first, second, and fifth rotational members being coupled to the input member, the fourth rotational member being coupled to the output member. The planetary gear transmission also has a separating clutch disposed between the elements of the second rotational member, for disengageably connecting the elements of the second rotational member.

A planetary gear transmission for use on automobiles includes an input shaft, an output gear, and three planetary gear trains disposed coaxially with each other and each having a sun gear element, a carrier element, and a ring gear element, two of the elements of each of the planetary gear trains being mechanically coupled to elements of the other planetary gear trains for rotation therewith. The elements which are mechanically coupled to each other provide first through fifth rotating members, the first and fifth rotating members being coupled to the input shaft, one of the second and third rotating members being coupled to the output gear, the fourth rotating member being coupled to the output gear. The planetary gear transmission also has a separating clutch disposed between the elements of the third rotating member, for selectively engaging and disengaging the elements of the third rotating member.

The solenoid valve 30 is mounted on the mounting member 10 with the inlet port section 31 positioned at the lower end thereof extending out downwardly from the bottom face of the mounting member 10, and this mounting member 10 is mounted on the base member 1 to cover the supplied oil path 2 and the discharged oil path 3 formed in the base member 1. The inlet port section 31 of the solenoid valve 30 extending out from the bottom surface of the mounting member 10 extends into the supplied oil path 2, thus the inlet port 31a and the supplied oil path 2 are communicated to each other. Furthermore, the outlet port 31b of the solenoid valve 30 is communicated to the discharged oil path 3 via the communicating groove 12 formed on the bottom surface of the mounting member 10. Also, the electric connector 21 is mounted on the mounting member 10 and the wiring members 25, 26 and 27 connecting the solenoid 36 of the solenoid valve 30 to this electric connector 21 are buried inside the mounting member 10.
摘要:
A system for controlling oil pressure of an automatic vehicle transmission having a plurality of fictional engaging elements (K1 ,K2,K3,B 1 ,B2) installed in the transmission for establishing a gear, a plurality of solenoid valves (SA and SE) at least one (SA) of which opens to supply the pressurized oil to at least one (K1) of the frictional engaging elements. The system also as a manual valve (20) whose spool moves in response to the selection of the selector lever for supplying the pressurized oil to the frictional engaging element bypassing the solenoid valve when the shift lever selects another gear range (1) in case of solenoid valve failure, and an underdrive engage control valve (30, 96) placed between the frictional engaging element and the switching valve for regulating pressure of the pressurized oil to be supplied to the frictional engaging. element in response to the pressurized oil outputted from the solenoid valve. In the system the underdrive engage control valve regulates the pressure of the pressurized oil to be supplied to the frictional engaging element in response to the pressurized oil supplied from the switching valve.

摘要:
A turning tool is arranged at a tool spindle of a composite working lathe to improve working efficiency.A composite working lathe (1) includes a first workpiece headstock (20) placed on a bed (10). A chuck (24) of a workpiece spindle (22) is rotated as holding a workpiece (K1). A tool headstock (100) arranged at a carriage (50) is rotated about B-axis while being linearly moved in the directions of X-axis, Y-axis and Z-axis. The tool headstock (100) operates a mill tool (110) and includes a comb-shaped cutting tool rest (150) having turning tools attached at the opposite side of a housing in a comb-shaped manner, so that turning processing can be performed with tool indexing in a short time.
