  • Patent number: 7533892
    Abstract: In one embodiment of the invention, a steering system for mobile medical equipment is disclosed including left and right steerable wheel assemblies including left and right steerable wheels, left and right parallelogram linkages coupled to the left and right steerable wheel assemblies, a steering function generator coupled to the left and right parallelogram linkages, and a steering tiller coupled to the steering function generator. The left and right parallelogram linkages transfer differing left and right wheel angles to the left and right steerable wheel assemblies respectively. The steering function generator generates the left wheel angle (LWA) of the left steerable wheel and the right wheel angle (RWA) of the right steerable wheel. The steering tiller receives an input steering angle to generate the left wheel angle and the right wheel angle to control the direction of the mobile medical equipment around flooring.

  • Patent number: 7530423
    Abstract: An operation torque estimating portion estimates an operation torque Th of a driver based on an input angle ?h and an input torque T output from a torque sensor. A non-holding state detecting portion determines whether the driver is holding a steering wheel by comparing an absolute value of the operation torque Th and a predetermined value ?1. An equilibrium detecting portion determines whether an equilibrium point is reached by comparing the absolute value of the input torque T with a predetermined value ?2. When it is determined that the driver is not holding the steering wheel and the equilibrium point is reached, a switching portion switches to such a position that causes a target steering adjusting portion to multiply a target output angle ? pm by a predetermined gain G according to the input torque T so that the target steering angle is made smaller.

  • Patent number: 7510040
    Abstract: A power transmission mechanism of a motorcycle includes a drive case which is disposed at the rear end of and outside of a rear swing arm, and which surrounds the axle of a rear wheel and incorporates a transmission device. In addition, the power transmission mechanism includes a drive shaft extending from an output shaft of an engine for transmitting power of the drive shaft to the rear wheel. The transmission device converts the direction of a driving force of the drive shaft and transmits it to the rear wheel. The drive shaft constituting part of the power transmission mechanism is disposed below the rear swing arm and the pivot shaft. The result is a motorcycle configuration that suppresses the vehicle width without expanding the rear swing arm.

  • Patent number: 7510045
    Abstract: A power-steering system, e.g., for a motor vehicle, having an electric motor, which transmits a steering-assist force via a belt transmission to a ball-screw transmission for displacing vehicle wheels, includes a cam, via which the ball-screw transmission and/or electric motor is supported in a steering-gear housing. The tension of a belt of the belt transmission is adjustable by rotating the cam in the steering-gear housing. The cam has at least one cutout on the circumference, and/or the steering-gear housing has at least one cutout in its inner wall. A locking element may be inserted into the cutout, in order to fix the cam in position with respect to the steering-gear housing.

  • Patent number: 7503415
    Abstract: An engine support bracket for a motorcycle is formed as an L-shaped channel member that is horizontally mounted on a vehicle body frame. Mounting portions of an engine are mounted on the L-shaped channel member and are fastened to the L-shaped channel member using a bolt. With this arrangement, assembling of the engine onto the vehicle body frame can be completed with a simple operation, and hence, the operability in assembling the engine is enhanced. Further, as parts for connecting the engine to the vehicle body frame, only the L-shaped channel member need be provided. Thus, the number of parts is decreased thus also providing a simple structure. Further, a head of the bolt and a nut, which fix the engine to the vehicle body frame, do not appear on a side surface of the mounting portions of the engine. Hence, the appearance of the motorcycle is enhanced.

  • Patent number: 7497453
    Abstract: A reciprocal upward and downward pedaling bicycle structure includes a main shaft of a free wheel at a chain wheel shaft, a driving body pivotally coupled to a frame of the main shaft, a pedal crank and a support rod on the driving body, and a driving belt linked to the main shaft and the support rod. An end of the driving belt is dragged to the frame by a resilient element. By the action of the resilient element ands the rotation of the main shaft, the crank and pedal are pulled by the driving belt to provide an upward bounce and the chain wheel drives the rear wheel shaft through the main driving belt. When the pedal is stepped downward, the main shaft and the chain wheel are rotated synchronously to drive the rear wheel of the bicycle to move forward.

  • Patent number: 7487985
    Abstract: A tilting, preferably three-wheeled, vehicle is disclosed that has a tilting mechanism that allows the vehicle to have leaning characteristics substantially similar to those offered by an in-line two-wheeled vehicle, but that does not require complex linkages and/or control systems to operate effectively. A tilting linkage is operably secured to a frame to allow a pair of spaced apart wheels to remain substantially aligned with the plane of the vehicle throughout its range of movement while still allowing the steering axes of each wheel to intersect the substantially vertical centerline of each wheel. The linkage also allows the caster angle of each wheel's pivot axis can be optimized independently of the angle of the vehicle's handlebar steering shaft.
