Problems solved by technology

These models have two steering axles and one or two driving axles. During the use of the vehicle, changes in the clearance of the steering rod system, deformation, and replacement of steering joints and tie rods will destroy the original steering relationship. The alignment parameters of the front wheels are incorrect, resulting in abnormal wear of the tires of the steering wheels, shortening the replacement cycle of tires, increasing fuel consumption, and increasing the cost of vehicle use
The measurement and adjustment of the front wheel alignment parameters of automobiles are generally carried out on the front wheel alignment test bench. In many places, there is no front wheel alignment test bench, so the measurement and adjustment of the front wheel alignment parameters of the car cannot be effectively carried out.

Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing:

[0024] (A) Preparation for toe-in and out-of-synchronization adjustments

[0025] 1. Use the tire pressure gauge to check and adjust the air pressure of the steering shaft tires so that the tire pressures of the steering wheels are the same;

[0026] 2. The sidewall of the steering wheel tire should be intact;

[0027] 3. The measuring site should be level;

[0028] 4. The vehicle should be in an empty state;

[0029] 5. Use jacks to support the double front axles that need to be adjusted one by one, and try to make the two front axles have the same height from the ground. The left and right steering wheels on the same axis have the same height from the ground. Safety.

[0030] (B) The vehicle is aligned

[0031] Such as figure 1 As shown, even if the vehicle is in a straight-line driving direction, it is the basis and key to adjust the toe-in and synchronization;

Abstract

The invention relates to an adjusting method of synchronization and toe-in of a double-front-axle steering vehicle, which is characterized by comprising the steps of preparing for the adjustment of tyre toe-in and asynchronization, adjusting the asynchronization between steering axles after a vehicle being parked in a correct place, and adjusting the toe-in of the vehicle. The positional parameters of front wheels can be measured and adjusted simply, effectively and accurately by adopting the method. The method solves the problem of abnormal abrasion of tyres caused by asynchronization among the toe-in and the steering axles. The method is effectively verified and used in the road tests of trucks.

Description

Technical field: [0001] The invention relates to a method for adjusting the synchronization and toe-in of a dual-front-axle steering vehicle. Background technique: [0002] With the implementation of the weight-based transportation policy on the roads of our country, 6×2 semi-trailer tractors, 6×2 trucks and 8×4 trucks are popular among transportation customers because of their light weight and more cargo. It became the main selling model in the commercial vehicle market in 2007. These models have two steering axles and one or two driving axles. During the use of the vehicle, changes in the clearance of the steering rod system, deformation, and replacement of steering joints and tie rods will destroy the original steering relationship, making the two If the alignment parameters of the front wheels are incorrect, the tires of the steering wheels will be worn abnormally, the replacement cycle of the tires will be shortened, the fuel consumption will increase, and the cost of ...
