Control and measurement tool of toe-in of front axle used for steering oil cylinder and provided with double transverse pull rods

Abstract

The invention relates to a control and measurement tool of the toe-in of a front axle used for a steering oil cylinder and provided with double transverse pull rods, comprising a measuring rod assembly and a measuring support assembly. The control and measurement tool is characterized in that the measuring rod assembly comprises an installation screw rod (1), a positioning sleeve (3) is sleeved on the installation screw rod (1), a joint ball bearing (2) is arranged outside the positioning sleeve (3), a flexible connection connector (5) is arranged on the joint ball bearing (2), the flexible connection connector (5) is connected with a measuring rod (6), and the measuring rod (6) is provided with a graduated scale (7); the measuring support assembly comprises a support (9), the support (9) is provided with a through groove, and the support (9) is provided with a chamfered edge positioning pin (11) and a circular positioning pin (10) on a steering knuckle brake caliper mounting bolt hole positioned at the other side of the front axle. The control and measurement tool disclosed by the invention has the advantage of reasonable structural design on appropriately selecting a positioning datum and a measuring datum, solves the problem that a main pin shaft line is not perpendicular to a measurement plane by adopting the joint ball bearing (2) and can swing front and back and enables the measurement and regulation data to be more accurate by simulating the diameter and the position of a front wheel tire by using a measuring support.

Description

technical field [0001] The invention relates to a toe-in control and measuring device for a front axle before leaving the factory, in particular to a toe-in control measuring tool for a front axle with double transverse tie rods in the middle of a steering oil cylinder. Background technique [0002] At present, the toe-in control of the double-tie-rod front axle with the center of the steering cylinder is adjusted and controlled by measuring the four-wheel alignment after the complete vehicle is assembled. This type of front axle cannot be controlled without the vehicle. However, the four-wheel alignment of large vehicles is not only a waste of money, but also very inconvenient to operate. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the toe-in control of the front axle with double tie rods in the center of the steering cylinder cannot be controlled. [0004] The technical solution adopted by the present invention to...
