摘要:
Monitoring system for maintenance of cars used for the purpose of automatically informing time for replacement of objects to be replaced, such as oil, filters etc. Said monitoring system includes a detector of engine operation for detecting operating time of cars (1), a variety of switches (3, 4, 5, 6) and sensors (7, 8, 9), a device for storing predetermined time of replacement of each object to be replaced (13), a device which deducts said operating time from said predetermined time of replacement and outputs the result of the deduction as a signal (12), and a multi-display (2) for displaying objects to be replaced on the basis of said output signal. In such a manner, operators or persons in charge of cars can surely notice the time of replacement of each object to be replaced by means of the information on the display (2); therefore, said object can be replaced at an optimum time for replacement without replacement time unnoticed.
摘要:
Automatic speed change method for a dump truck for a construction machine, which method improves fuel economy by utilizing effectively an engine output and durability of a power transmission system and provides comfort riding. This method can select a desired and optimum stage of speed in accordance with a load state of the dump truck and/or an output state of the engine by utilizing a controller (50, 60) with a built-in computer.

摘要:
A device comprises a transmission lever (1), a shift position sensor (2), a rotation sensor (3) to measure the rotation speed of a power shaft (9), an inclination gauge (4) to detect the slope of a road surface, a pay-load meter (5) to detect the load of the car, an automatic transmission control device (6), a solenoid valve (7), an engine, a torque converter and a transmission device (8). An optimum speed stage for starting a car is selected by the control device (6) according to the load of the car and the slope of the road surface, i.e the lowest gear is selected for a large load whereas a higher gear is selected for a small load.
摘要:
A technology for the purpose of starting always at an optimum speed stage according to the level of load of a car, which is employed for an automatic transmission which shifts up or shifts down by one stage successively the speed stage of the transmission according to the state of load. In the device for selecting starting speed stage, a speed stage at the starting of a car is selected according to the measured state of ' load of the car and the slope of road surface.
