Embodiment Construction

[0065] A specific embodiment of the power steering device employed in the present invention will be described below with reference to the accompanying drawings. An embodiment of the present invention will be illustrated by using a so-called saddle-type four-wheeled cart A incorporating the power steering device of the present invention. A detailed description of structures other than the main power steering device is omitted. In the accompanying drawings, symbol A represents a four-wheeled light vehicle, and symbol 7 represents a power steering device.

[0066] like figure 1 As shown, the four-wheel light vehicle A according to the embodiment of the present invention comprises a body frame 1, a suspension system 2, a pair of front wheels 3, a pair of rear wheels 4, an engine part (not shown), a seat part 5, a power control device 7 , and handle 8. The vehicle body frame 1 serves as a skeleton structure. The bottom of the suspension system 2 is connected with the body frame...

Abstract

The present invention provides a power steering apparatus for being protected from mud or dust, or rainwater. A sub-steering unit is provided together with a torque sensor of the power steering apparatus used in a vehicle. A steering shaft portion includes an input shaft and an output shaft, each being rotatably supported. A torque sensor portion is connected for joining the input shaft and the output shaft with the torque sensor portion sensing an amount of torque. A power assist portion is engaged with the output shaft for assisting the steering based on the amount of torque sensed by the torque sensor portion and the like. A sub-steering portion is engaged so as to connect the input shaft with the output shaft while circumventing the torque sensor portion and reducing the amount of torque. The power steering apparatus includes a column cover for covering the sub-steering portion as well as the torque sensor portion.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority under 35USC 119 from Japanese Patent Application Nos. 2004-289417, 2004-289369 and 2004-289408 filed on September 30, 2004, the entire contents of which are incorporated herein by reference. technical field [0003] The invention relates to a power control device for assisting in the control of a vehicle with a handle. Background technique [0004] For example, a four-wheeled buggy is known as a saddle-riding vehicle. For a four-wheeled buggy configuration, the front wheels are steered by a steering mechanism that includes a handle. [0005] In heavily loaded vehicles with steering wheels, a predetermined gear ratio is used to reduce the speed at which the front wheels are steered relative to the steering angle of the steering wheels, thereby providing auxiliary power to steer the front wheels. On the other hand, a light vehicle such as a four-wheeled buggy does not require gear reduct...
