摘要:
A wheeled chassis having separately and independently pivotable drivewheels attached to a generally rectangular frame. The axis of reorienting rotation of one of the drivewheels is offset relative to the reorienting axis of the other drivewheel to produce stable, controlled, and efficient multidirectional motion.

An apparatus for controlling a vehicle which prevents a frequent gear shift called “busy-shift” caused by a varying driving condition. A plurality of wheels, a first power source, a second power source, an electric power supply, and a transmission between the wheel and at least one of the power sources are mounted in the vehicle. The apparatus for controlling the vehicle includes a detecting and a torque change. The detecting means detects a selected gear ratio of the transmission. Since torque of the second power source is increased or decreased in response to the selected gear ratio which is detected by the detecting, a fluctuation of the driving torque of the vehicle is restrained. Consequently, a frequent gear shift “busy-shift” can be avoided.

A vehicle powertrain includes a fuel cell power source, an electronic control unit, and an electrical energy storage and retrieval assembly, which are interconnected to communicate electrical power. The powertrain also includes a multi-range electro-mechanical transmission, which supplies driving power to the transmission output shaft and from there to the vehicle drive wheels and also supplies power to a power take-off drive unit, such that cooling airflow and hydraulic power is supplied to the vehicle.

A device controls the operating conditions of a self-propelled vehicle. The device includes a first device for controlling the travelling speed of the self-propelled vehicle, and a second device for controlling the output speed of an internal combustion engine. The first and second devices are separate from each other.
摘要:
A driving system for an industrial truck, comprising: a combustion engine, an electric motor fed from a battery, a gear assembly the inputs of which are coupled to the shaft of the combusion engine and the electric motor and the output of which is coupled to the driven shaft of the driving system.

First and second dynamo-electrical machines are provided. A first rotor forming the first dynamo-electrical machine together with a second rotor is connected to either one of a front driving shaft and rear driving shaft. A second rotor forming the second dynamo-electrical machine together with a stator is connected to another one of the front driving shaft and rear driving shaft. As a result, a torque generated by the first dynamo-electric machine is transmitted to either one of the front and rear driving shafts, connected to the first rotor. A torque which subtracts a reaction torque caused by the torque generated by the first dynamo-electric machine from a torque generated by the second dynamo-electric machine is transmitted to another one of the front and rear driving shafts, connected to the second rotor.
摘要:
A maneuverable self-propelled cart having a drive assembly including independently suspended drive wheels for propelling the cart over rough or uneven surfaces. The drive assembly is comprised of a drive wheel carriage having at least two drive wheels. The drive wheel carriage may include a turntable or the like adapted to rotate the carriage about a substantially vertical axis relative to the frame of the cart. Each drive wheel may be independently suspended beneath the cart frame by a suspension apparatus so as to allow each drive wheel to individually engage a ground or floor surface.

The invention relates to a multi-motor drive in which two electric motors which are assigned to a common output with a dual-stage gearbox are provided. An automatic controller controls, on the one hand, the load distribution between the motors and, on the other hand, the gearbox in order to ensure an optimum degree of efficiency of the drive. Asynchronous motors are preferably provided.
摘要:
A vehicular transmission comprises an engine E, a continuously variable transmission CVT and a starting clutch 5. The driving force from the engine E is conveyed through the continuously variable transmission CVT with a speed change to a countershaft 2, and the starting clutch 5 is used to convey this driving force from the countershaft 2 to wheels of a vehicle. The continuously variable transmission CVT is hydraulically controlled by a control valve CV which receives control signals through a line 35 from an electrical control unit ECU. When the temperature of the oil used for engaging and disengaging the starting clutch 5 is equal to or higher than a predetermined temperature, the transmission allows the engine E to stop operating. This control to terminate the operation of the engine is an idling elimination control and is achieved by terminating the fuel supply to the engine and by maintaining the resulting condition of non-fuel supply while the vehicle is being decelerated and brought into a halt.
