Problems solved by technology

A complete theoretical system has not been established in the design of the multi-mode coupling mechanism scheme. At present, the kinematics and dynamics analysis of the scheme is carried out in the known specific coupling mechanism transmission diagram, and on this basis, according to the overall performance index requirements of the vehicle , to match the power requirements of the engine, generator and motor, often due to the limitations of the scheme itself, the motor requires a large power, which is difficult to meet the requirements of the high-power tracked vehicle transmission system

Embodiment Construction

[0078] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0079] The present invention provides a method for optimizing the power coupling transmission scheme of double motors and double planetary rows. The method includes the following steps:

[0080] Step 1: Determine the optimal principle of the basic components in the power coupling transmission;

[0081] Step 2: find out the possible power coupling transmission scheme composed of basic components according to the permutation and combination method;

[0082] Step 3: Find the optimal power coupling transmission scheme from the possible power coupling transmission schemes.

[0083] Generally, according to the basic theory of multi-degree-of-freedom planetary transmission, the number of basic components of the coupling mechanism is n+p, where n is the number of degrees of freedom of the coupling mechanism, and p is the number of planetary rows. Therefore, it can ...

Abstract

The invention provides a dual-motor and double-planet-row power coupling transmission scheme optimization method. By means of a multi-freedom-degree planet transmission component comprehensive analysis method, possible power coupling transmission schemes of basic component composition of double planet rows are analyzed and optimized, and the optimal power coupling drive scheme suitable for an electromechanical composite transmission system driven by motors on the two sides is achieved. On the basis of the composition theory of components forming the planet rows, all feasible power coupling transmission schemes can be found through a systematic and strict method; in the feasible power coupling transmission schemes, the unusable schemes can be phased out step by step according to the optimization principle, and the scheme with the optimal performance can be selected at the highest speed; the method can be conveniently and easily achieved through software by means of computer languages; and the method has the beneficial effects of being universal and extensible.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission, and in particular relates to a method for optimizing a dual-motor dual-planetary row power coupling transmission scheme. Background technique [0002] The power coupling transmission device has always been the core component of the electromechanical compound transmission vehicle, and it is also the focus of related research at home and abroad. The electromechanical coupling device launched by Renk Company in July 2006 uses a single planetary row. Mode coupling mechanism, but its speed regulation range is narrow, the vehicle control strategy is complicated, and the technical realization is difficult. [0003] In China, a relatively comprehensive and in-depth comparative analysis of hybrid transmission series, parallel, and single-mode hybrid forms is carried out, as well as a single-mode coupling mechanism composed of a single planetary row is analyzed, and schemes are compared in ...
