Problems solved by technology

[0002] When measuring the height of the center of mass based on the traditional wheel load meter, the front axle wheel is lifted, and the height of the center of mass is calculated according to the lifting height and the weight change of the rear axle. This requirement for the measurement of the center of mass height of heavy-duty and multi-axle vehicles will make the rear axle load too large , many models simply cannot achieve

Embodiment 1

[0035] A center-of-mass position measuring device based on a forward tilting platform and a wheel loader, which consists of: a drive cylinder, a bearing platform and a wheel loader, the bottom of the drive cylinder is connected to the foundation through bolts, and the top of the drive cylinder Supporting the bearing platform, the lower part of the bearing platform is connected with the connecting hinge, and a group of the wheel load meters are evenly placed on the bearing platform, and the upper part of each of the wheel load meters corresponds to For the corresponding wheels, the wheel load meter can normally measure wheel load data in a horizontal state.

Embodiment 2

[0037] A method for measuring the center of mass position measuring device based on the forward tilt platform and the wheel load meter described in embodiment 1, the method comprises the following steps:

[0038] (1) Wheelbase measurement: measure the wheelbase of the vehicle separately

[0039] (2) Wheelbase measurement: measure the wheelbase of the vehicle separately

[0040] (3) Wheel height measurement: measure the wheel height of the vehicle

[0041] (4) Arrange the position of the wheel loader according to the wheelbase and wheelbase;

Abstract

The invention provides a device and a method for measuring the location of center of mass based on a forward tilting platform and a wheel load meter. When the traditional wheel load meter is used formeasuring the height of the center of mass, the front axle wheel is lifted, and the height of the center of mass is calculated according to the lifting height and the weight change of the back axle; when the height of the center of mass of the heavy and multi-axes vehicles is measured, the load on the back axle is too large, and the measuring cannot be performed. The device is characterized in that multiple wheels are used for simultaneously loading, so as to measure the height of the center of mass of the heavy and multi-axes vehicles. The device for measuring the location of the center of mass based on the forward tilting platform and the wheel load meter consists of a driving cylinder (1), a loading platform (2) and the wheel load meter (3), wherein the bottom part of the driving cylinder is connected with a ground foundation through a bolt; the top part of the driving cylinder is used for supporting the loading platform; the lower part of the loading platform is connected with a connecting hinge (4). The device is used for measuring the locations of the centers of mass of automobiles and engineering vehicles.

Description

Technical field: [0001] The invention relates to a center-of-mass position measuring device and a measuring method based on a forward tilting platform and a wheel load meter. Background technique: [0002] When measuring the height of the center of mass based on the traditional wheel load meter, the front axle wheel is lifted, and the height of the center of mass is calculated according to the lifting height and the weight change of the rear axle. This requirement for the measurement of the center of mass height of heavy-duty and multi-axle vehicles will make the rear axle load too large , Many models simply cannot be realized. Invention content: [0003] The object of the present invention is to provide a center-of-mass position measuring device and method based on a forward-inclining platform and a wheel load meter. Multiple wheels are loaded at the same time, and the height of the center of mass of heavy-duty and multi-axle vehicles can be measured. [0004] Above-ment...
