JPS62194917A - Spring for preventing trailer from rolling - Google Patents

Abstract

PURPOSE:To provide a mowing disc which requires no polishing, by providing such an arrangement that six of thin steel strips each formed, in lower section in the rotating direction, with a cut-out part which is hooked on two projections on the associated leaf spring, are fitted in a rotary disc, radially of the latter. CONSTITUTION:For example, a cut-out having dimensions of 1mm width and 2mm length is formed in a steel strip having dimensions of 10mm width and 75mm length and made of a steel plate having a thickness from 0.5 to 0.3mm, downward in the rotating direction. The thus formed cut-out is hooked onto projections formed on a leaf spring 2 to prevent the steel strip 1 from being exerted with a force which tends to move the steel strip 1 outward. Six of such steel strips are prepared and are fitted in a rotary disc so that they extend radially from the center of the disc at a leading angle of 15 deg. with respect to the rotating direction. The cutting capability line of each steel strip 1 has about 5mm while the adjusting capability of each leaf spring 2 is 2mm, and therefore, when the cutting capability line is reduced to 2mm, the leaf spring 2 is raised to obtain a capacity of 3mm. As a result it is possible to eliminate the necessity of polishing the steel strips severing as a cutter.

Description

DETAILED DESCRIPTION OF THE INVENTION The trailer rollover occurs with excessive frequency.
The repulsion of the circular motion force is used to make the shape of the motion force move, and the motion applied to the outer diameter becomes violently strong. The rear and outer diameter of the trailer have the same Mtr force.

The fulcrum is generated in the center of the train to absorb the force at an early stage, and the balance of the pieces divides the force between the left and right sides to prevent overturning, reflecting the ability of the puller.

The trailer's body tires (inside number 1) try to move sideways on the road, but they make strong contact or roll over, absorbing the force.

A sprue/g (number 2 in the figure) that suppresses the force by 9 is added to the conventional spring (number s+3 in the figure). I see an improvement of more than 100%, probably due to the ability of the spring. The conventional SPRIN I has a strong force against road noise and loaded load, and does not work strongly against the wind force. In particular, the travel distance between the upper and lower springs of a trailer that carries a heavy load is short and cannot absorb lateral forces.

A spring (inside number 2) that absorbs lateral force is installed on the rear wheel of a trailer with the same weight.
