Embodiment Construction

[0017] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] The invention realizes the calculation of the meshing power loss of the driving gear teeth and the track shoes:

[0019] The force analysis diagram of the meshing friction resistance between the driving gear teeth and the track shoes is as follows figure 1 as shown,

[0020] Depend on figure 1 It can be seen that the contact normal force is:

[0021]

[0022] In the formula: F N Contact normal force; F T is the meshing tangential force; α ω is the friction angle between the track pin and the driving gear teeth.

[0023] The contact friction force is:

[0024] f R =μ 5 f N (2)

[0025] In the formula: F R is the contact friction; μ 5 is the coefficient of contact friction (an empirical value).

Abstract

The invention relates to a calculation method for power loss of a crawler traveling device, and relates to the technical field of crawler vehicles. The present invention proposes a solution to the problem by analyzing the frictional force and frictional displacement between the teeth of the drive wheel and the track, the analysis of the relationship between the rolling resistance of the road wheel and the track and the speed of movement, and the analysis of the power loss of the torsional deformation of the rubber pin of the track plate. The calculation method of the power loss of the tracked driving device has high calculation accuracy, and provides data support for the power matching of the tracked vehicle and the power selection of the power system.

Description

technical field [0001] The invention relates to the technical field of crawler vehicles, in particular to a calculation method for power loss of a crawler traveling device. Background technique [0002] The problem of calculating the power loss of the crawler driving device has been in a technical blank state for a long time. The main reason is that engineers and technicians focus too much research on the development of new products and new technologies, ignoring the calculation of product performance. With the refinement of vehicle power distribution, the quantitative analysis of the power demand and power loss of each system is becoming more and more urgent. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is: how to realize the calculation of the power loss of the crawler action system, so as to realize the power matching of the crawler vehicle and the power selection of the powe...
