摘要:
A vehicular drive system is provided with at least one electric motor and a bevel gear portion which are accommodated within a casing formed by a plurality of casing members fixed to each other, wherein: said casing includes a first casing member to which a stator of each of said at least one electric motor is fixed, and a second casing member which is fixed to said first casing member so as to cooperate with said first casing member to form a space accommodating said at least one electric motor and which has a support portion supporting said bevel gear portion; and a rotor of said each electric motor is rotatably supported at opposite ends thereof by said first casing member and said second casing member, respectively, while said bevel gear portion is rotatably supported by said second casing member through said support portion.

In a drive assembly of the invention, a first catch tank is provided above a casing that keeps lubricating oil accumulated in a bottom thereof for immersion of part of a rotor of a motor MG3 and of part of a differential ring gear of a differential gear. The first catch tank temporarily keeps the lubricating oil scooped up from the bottom of the casing by the rotation of the differential ring gear. The lubricating oil kept in the first catch tank is flowed down by the force of gravity and is fed to peripheral bearings. A second catch tank is arranged to temporarily keep the lubricating oil scooped up from the bottom of the casing by the rotation of the rotor of the motor MG3. The lubricating oil kept in the second catch tank is flowed down by the force of gravity and is fed to peripheral bearings. This arrangement desirably shortens oil paths connecting the respective catch tanks to the peripheral bearings and ensures smooth supply of the lubricating oil to all the peripheral bearings and other oil-requiring sites.

A hybrid vehicle including: an engine and a motor-generator for outputting drive forces to run a vehicle; and a brake pedal for applying a braking force to the running vehicle. While an engine braking force is being established, it is detected that the brake pedal is depressed. After this depression of the brake pedal, the vehicle speed is detected so that the regenerative braking is effected by the motor generator on the basis of the detected vehicle speed.
摘要:
A transmission for changing a path to transmit a torque by changing the state of torque transmission to a rotary member, comprising: an active material for changing its state when fed with an electric signal; and a coupling mechanism for effecting or intercepting the torque transmission to the rotary member in accordance with the state change of the active material.

A hybrid vehicle having an engine and a motor to be controlled independently of each other for running the vehicle. This hybrid vehicle is given a braking demand detecting function to detect a braking demand through an idle ON of the engine while the vehicle is running, and a first braking function to suppress the rise in the vehicle speed of the vehicle by a regenerative braking force of the motor if the braking demand is detected by the braking demand detecting function.
摘要:
A hybrid vehicle drive system including an electric motor operated by electric energy, an engine operated by the combustion of a fuel, a transmission, and a synthesizer mechanism. The synthesizer includes a hydraulically operated clutch system and mechanically synthesizes the output of the engine and the output of the electric motor for transmitting a resultant of these outputs to the transmission. The synthesizer mechanism and the transmission are disposed adjacent to each other, to simplify piping arrangements for supplying the clutch system with a working fluid and lubricating the synthesizer mechanism and transmission.
摘要:
An apparatus for controlling a vehicle continuously variable transmission, including a directional control valve having a first spool movable between a shift-down and a shift-up position, a flow control valve including a second spool movable between a flow-restricting and a non-restricting position, and a first and a second solenoid-operated valve for applying an actuating pressure to the first and second spools. The directional and flow control valves and the solenoid-operated valves are adapted such that the first and second spools are moved toward the shift-up and flow restricting positions, respectively, when the actuating pressure is not applied to the spools, or when solenoid coils of the two solenoid-operated valves are both off. The directional control valve may have a shift-down chamber for receiving a pilot pressure to move the first spool to the shift-down position when a failure of one of the solenoid coils exists while the vehicle speed is lower than a predetermined limit.
摘要:
A power transmission endless chain belt connecting two pulleys, including a belt body having multiple sets of link plates each set consisting of a plurality of parallel link plates, each of which has a pair of pin holes. The belt body further has multiple pins inserted into the pin holes such that the link plates of one set are pivotally connected to the link plates of the adjacent sets. The chain belt further includes multiple pairs of blocks each pair having opposed mutually rolling surfaces, each pair of blocks having an aperture through which the link plates of the corresponding set extend. The pins define first bending points of the belt. One of the pin holes formed in each link plate has a larger size than the other pin hole, and cooperates with the corresponding pin, to define a clearance therebetween. The link plates of each set are arranged such that each pin extends through one of the pair of pin holes in at least one of the link plates of each set, and the other of the pair of pin holes in the remainder of the link plates of the same set. The rolling surfaces of the multiple pairs of blocks define second bending points of the belt. Each second bending point is located between adjacent ones of the first bending points, whereby a bending pitch of the belt is equal to a distance between the adjacent first and second bending points.
