Wheel angle measuring device, multi-axle steering vehicle and wheel angle measuring method

Abstract

The present invention relates to a vehicle wheel corner measurement device, a multi-axis turning vehicle and a vehicle wheel corner measurement method. The vehicle wheel corner measurement device is used for measuring the turning corner of the wheels on a vehicle. The vehicle includes an axle and a knuckle, the wheels are fixed on the knuckle, and the axle is rotatingly connected with the knuckle. The device includes an axle soleplate, a fixed connection device and a corner caliber. The axle soleplate is fixedly installed on the axle, the corner caliber includes housing and a rotating shaft, the corner caliber is fixedly installed between the knuckle and the fixed connection device, the rotating shaft is rotated relative to the housing, the fixed connection device is fixedly connected with the axle soleplate, and the angle measured by the corner caliber is the rotation angle of the wheels. The device provided by the invention employs a direct measurement mode to accurately measure the rotation angle of the wheels without changing the structure of the original axle and the knuckle so as to save lots of manpower and material resources; and moreover, the vehicle wheel corner measurement device, the multi-axis turning vehicle and the vehicle wheel corner measurement method are convenient in installation, firm and reliable and facilitate popularization.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a wheel angle measuring device, a multi-axle steering vehicle and a wheel angle measuring method. Background technique [0002] Special vehicles in the fields of heavy-duty trucks, heavy cranes, heavy-duty engineering vehicles, national defense and aerospace, etc., have large tonnage, long body, high center of mass, and harsh working conditions, so the entire vehicle generally has more than three axles, and the steering axle is not less than two axes. Due to the limitations of technical conditions, these vehicles are generally front-wheel steering, but when the vehicle is running at low speeds, there are problems such as slow steering, large turning radius, uncoordinated movement trajectories of front and rear wheels, and serious tire wear; When driving, serious steering distortion occurs, and tail flicking is very easy to occur. [0003] At present, the most effective way to ...

However, the measuring device of this scheme has a complex structure and is inconvenient to install, and it is necessary to ensure that the swing rod and the pull rod are on the same level, otherwise it will cause measurement errors. In addition, due to parts manufacturing and assembly, the wheel angle will also error in the measurement
