摘要： An automatic transmission for motorcar of the type including a main transmission and an auxiliary transmission is disclosed. The auxiliary transmission has a plurality of speed changing stages and when it assumes a certain lower speed stage, any speed changing to higher speed stage is inhibited in the main transmission. The main transmission is provided with a solenoid valve which makes it possible to carry out speed changing to higher speed stage when it is turned on, while the auxiliary transmission is provided with a hydraulic control device which is communicated with a hydraulic servo via a hydraulic passage. The hydraulic servo is operatively associated with a speed reduction frictional engagement element which allows the auxiliary transmission to assume a certain lower speed stage. The solenoid valve is electrically connected to a pressure switch which is so constructed that it is turned off when the hydraulic servo is supplied with hydraulic oil and it is turned off when hydraulic pressure is released from the hydraulic servo. When the auxiliary transmission assumes a certain lower speed stage, the hydraulic servo is supplied with hydraulic oil and the solenoid valve is turned off. Thus, any speed changing to higher speed stage is inhibited in the main transmission.

摘要： A lubrication system is provided for a transmission mechanism supported on input and output shafts, and a chain drive rotatably connects these shafts. The chain and drive elements on the shafts are provided with a casing for isolating the mechanism, which collects an oil bath within the bottom of the transmission casing for lubricating a chain or other transmission member. An oil pump supplies oil from a reservoir to various areas to be specifically lubricated within the transmission. Feed means associated with the oil pump regulates the level of the transmission oil bath. The system may additionally contain an oil strainer, an external cooler, a relief valve to limit the pressure from the oil pump, or various combinations of such elements. The various points of lubrication within the casing, in turn, drain into the casing. Oil level within the transmission casing is regulated to keep the level low and at the same time to maintain sufficient oil for lubricating the chain.

摘要： A transmission control system for controlling a transmission. The system has a main transmission with a speed changing mechanism and an output shaft, a substransmission connected to the output shaft, and a control system for receiving outputs from a number of sensors which sense the running state of the vehicle. The control system itself has two outputs, there being two separate hydraulic controls connected to the two system outputs, respectively. The two hydraulic controls control the speed changing mechanisms of the main and subtransmissions, respectively. Also provided is a hydraulic pressure source which supplies a working fluid to the two hydraulic controls. The control system determines whether the main and subtransmissions are in a transient period of the speed changing operation and, as long as one of the two transmissions is in the transient period, inhibits the speed changing operation of the other transmission.
