A single drive three pivot fork lift truck includes a steering bridge, a steering motor that drives the steering bridge, and at least one rear wheel that is connected to the steering bridge. The forklift truck also includes a first sensor that senses rotational position of a steering wheel, a second sensor that senses rotation of the steering motor, and a controller that receives signals from the first sensor and second sensor and controls the steering motor. The forklift truck also includes a battery carried by the truck frame in a battery compartment located at the rear of the forklift truck, which can take the place of counterweight blocks.

A cutting apparatus including a plurality of types of holding members holding a workpiece and a plurality of types of cutting members cutting the workpiece held by the holding member. Each holding member includes a sheet of base, a holding portion disposed on a surface of the base and having a holding capacity suitable for a type of the workpiece to be held, and a holding member indicator capable of distinguishing the types of holding members. Each cutting member includes a cutter having a blade configured to cut the workpiece and having a cutting capacity suitable for a type of the workpiece to be cut, a support portion supporting the cutter, and a cutter indicator provided on the plurality of types of cutting members and capable of distinguishing the types of cutting members, the cutter indicator being similar in configuration as the holding member indicator of corresponding holding member.

A continuously variable speed transmission and steering differential having a central drive axle, two pairs of sheaves and two shift arms. The drive axel is driven by an external power source. The two pairs of sheaves, left and right, are mounted to the drive axel. Each pair of sheaves includes a fixed drive sheave and a movable drive sheave. Each movable drive sheave is positioned by a shift arm. Shifting the shift arms left or right varies the gear ratio between the left and right pair of sheaves thereby providing steering control. Narrowing the distance between the shaft arms increases the gear ratio and consequently puts the transmission into a higher gear, thereby providing speed control.

A steering assist mechanism for use in a vehicle having a steering linkage and an engine. The steering assist mechanism includes a driving unit having input and output ends. The output end being connected to the steering linkage. The steering assist mechanism also includes power take-off means adapted to connect the engine to the input end of the driving unit. The steering assist mechanism further includes an electromagnetic clutch in the driving unit between the input and output ends, and control means which are responsive to the torque exerted through the steering linkage to increase the energization of the clutch, whereby the steering linkage is driven by the power take-off means in a direction tending to reduce the torque.

A belt driven power steering system for use in a vehicle to eliminate energy waste. The belt driven power steering system includes a belt driven pulley powered by an engine crankshaft in the vehicle; a first gear operably connected to the pulley via a first shaft, the first gear providing power rotation in one direction; a second gear aligned with and driven by the first gear, the second gear providing power rotation in a direction opposite to the power rotation of the first gear; power control means operably connected to the first gear and to the second gear to provide power in the desired direction; a steering system operably connected to the power control means to steer the vehicle to the left or to the right; a steering wheel operably connected to the power control means wherein the power provided to the control means is based on driver input to the steering system via the steering wheel; and torque sensing mean for sensing the torque applied to the steering wheel by the driver input to steer the vehicle in a direction to the left or to the right.

Steering wheel return assist mechanism for use in a vehicle having a steering column assembly rotatably supporting a steering shaft comprises a spring operated return assist device which permits a limited degree of free rotation of the steering shaft before activation of the mechanism. The return assist device urges the shaft and the steering wheel to a near central neutral position after rotation of the steering wheel. In a second embodiment, a second return assist means structured substantially the same and spaced axially apart and inverted along the steering shaft from the first return assist means is disclosed so that the steering shaft is urged to a near central neutral position after the steering wheel has been turned in either direction.
摘要:
A method of, and a device for, controlling the rotation of an element about an axis are disclosed. A continuous torque is exerted on the element to rotate it in one direction, and a control member engages with one end of a wrap spring, which extends around a cylindrical part of the element, to preclude rotation of the element when the control member is in a first position. When the control member is out of the first position, the wrap spring loosens about the cylindrical element, thereby allowing the element to rotate under the continuous torque. However, rotation of the element under the continuous torque indirectly causes the control member to return to the first position, thus preclouding further rotation of the element.
