Abstract: PURPOSE:To improve a rate of fuel consumption in an engine as well as to reduce a noise during operation of a hydraulic unit, by driving an air compressor or an oil pump with an electric current produced in a retarder at a time when a solenoid type retarder operates. CONSTITUTION:During car driving, when a retarder switch 11 is turned on, an exciting current flows in an exciting coil of a retarder unit 5 whereby a magnetic circuit is formed in space between the coil and teeth 6 of a flywheel 3. In consequence, a core of the side exciting coil and these teeth 6 come into a state of being attracted with each other so that braking force works on the flywheel 3.

Title: Running speed change gear for tractor
Inventor: NISHIKAWA FUMIAKI
IPC: F16H59/40
Filed: 1988-07-18
Abstract: PURPOSE:To perform accurate speed change by automatically taking the timing of shift up control by a method wherein automatic operation control is made so that automatic shift up to a next speed change position is effected after the number of revolutions of the output shaft of a speed change clutch attains a proper value. CONSTITUTION:Speed change is transmitted through engagement of a speed change clutch 2, and rotation of an output shaft 3 on the output side through the speed change clutch 2 is increased gradually. After the number of revolutions of the output shaft 3 attains a proper value, next shift up is automatically effected. Since the speed change by automatic shift up is gradually effected after the speed change clutch 2 is brought into an engaging state, shift up is made at a point of time when the slip of the speed change clutch 2 is prevented from occurring. Therefore, the timing of shift up control can be automatically taken according to the oil temperature of a power shift transmission and the magnitude of a load exerted on a vehicle to perform proper speed change.
