Problems solved by technology

In this invention, since the axes of the sheave shaft and the pin shaft intersect each other, the steel rope must be tight and loose during steering, causing the steering gap to be large and small, which may induce the phenomenon of "shimming" in the steering wheel. At the same time, the invention does not have Braking device, so this steering device lacks steering reliability and driving safety, so it is not suitable to be promoted in four-wheeled vehicles as a means of transportation

Abstract

The steering mechanism for four-wheel vehicle includes steering rod assembly, steering link rod mechanism and steering gear connected to the steering rod assembly and the steering link rod mechanism. The steering gear includes shaft, wire coiling wheel fixed on the shaft, steel wire wound on the wire coiling wheel and one pair of elastic connector with one end connected to the steel wire and the other end hinged to the steering link rod mechanism. The present invention has simple structure and easy manufacture, may be matched with elastic suspension and used to realize no-interval steering transmission. The present invention may be used widely in various kinds of miniature four-wheel vehicles and three-wheel vehicles.

Description

【Technical field】 [0001] The invention relates to a steering device, in particular to a steering device for a four-wheel vehicle. 【technical background】 [0002] The steering system of a four-wheel vehicle is a complex device. In the prior art, the mechanical steering gears adopted by large-scale motor vehicles and modern cars are reliable in operation and light and flexible in operation, but the steering gear with brakes is complex in structure and heavy. General miniature four-wheel bicycles and miniature four-wheel electric vehicles do not It may be used; while the steering device of an ordinary four-wheel stroller is simple, but the steering clearance is large and the steering transmission ratio is small. Tool for use in miniature quadricycles. Chinese patent 86207191 discloses a kind of four-wheel vehicle steering device, and this device drives sprocket wheel by steering wheel, pulls connecting rod by chain, steel rope, makes steering wheel deflect around bearing pin ...
