A wheel milling machine rocker mechanism capable of lifting and turning

Abstract

A wheeled milling-planing machine rocking arm mechanism capable of achieving lifting and falling steering is composed of parts: a rocking arm frame, a linear hydraulic cylinder, a front rocking arm, a rear rocking arm, a front rocking lower arm, a rear rocking arm lower arm, a front steering oil cylinder, a rear steering oil cylinder, a walking motor, a vehicle wheel frame, vehicle wheels, an upper rocking arm shaft, a front rocking arm shaft, a rear rocking arm shaft, angular plates and idler wheel groups; the upper sides of the front rocking arm and the rear rocking arm are hinged through the upper rocking arm shaft, and the lower sides of the front rocking arm and the rear rocking arm are respectively hinged with two ends of the linear hydraulic cylinder through the front rocking arm shaft and the rear rocking arm shaft; the upper rocking arm shaft is limited in a vertical sliding chute of the rocking arm frame to slide through the idler wheel group, and the front rocking arm shaft and the rear rocking arm shaft are limited in a left horizontal sliding chute and a right horizontal sliding chute of the rocking arm frame to slide respectively through the idler wheel groups on the angular plates; the lower ends of the front rocking arm and the rear rocking arm are hinged with flanges fixedly connected with the steering oil cylinders through pin shafts respectively; the upper ends of the front rocking arm lower arm and the rear rocking arm lower arm are respectively connected with the angular plates through pin shafts, and the lower ends of the front rocking arm lower arm and the rear rocking arm lower arm are hinged with the flanges fixedly connected with the steering oil cylinders through pin shafts; the steering oil cylinders are connected with the walking motor and the vehicle wheels through the vehicle wheel frame.

Description

technical field [0001] The invention relates to a rocker mechanism of a milling machine, in particular to a rocker mechanism which can realize the height lifting of the body of a wheeled milling machine and can simultaneously provide the front and rear wheels with larger steering angles. It belongs to the technical field of engineering machinery. Background technique [0002] At present, the body lifting mechanism of the wheel milling machine is basically controlled by a hydraulic cylinder vertical to the ground. The upper end of the hydraulic cylinder piston is connected to the vehicle body, and the other end of the piston is connected to the traveling mechanism. The walking mechanism is mainly composed of wheels, hydraulic motors and their installation parts. The wheel mounts are always perpendicular to the ground. The milling drum is connected with the vehicle body, and the lifting of the milling mechanism is controlled by controlling the lifting of the oil cylinder. S...

AI Technical Summary

Problems solved by technology

Such a vertically arranged oil cylinder bears the weight of the vehicle and the thrust when the vehicle is running, which is a shear force for the oil cylinder, and the force of the oil cylinder is complicated, which is not good for its life and performance.
