Integrated transmission case integration technology and overall arrangement scheme

Abstract

The invention discloses an integrated transmission case integration technology and an overall arrangement scheme. The integrated transmission case comprises a comprehensive transmission device box body, a front transmission mechanism, a speed change mechanism and a steering mechanism, wherein a front end of the comprehensive transmission device box body is connected with an output end of an engine, and power of the comprehensive transmission device box body is outputted through the two sides; internal transmission of a box body of the comprehensive transmission device is composed of a front transmission mechanism, a speed change mechanism and a steering mechanism, an integrated transmission box integration technology and an overall arrangement scheme are adopted, a double-pump and double-motor driving control technology is adopted, continuous steering adjustability and small-radius steering power circulation control are achieved, meanwhile, the arrangement scheme is more advanced, the integration degree is improved, the ton power can be increased to 280 kW / t, the transmission power can be 360 kW, the comprehensive transmission weight is 1285 kg, meanwhile, redistribution of flow balance and transmission lubrication is carried out based on a multi-pump-source complex hydraulic system driven by double pumps and double motors, and the integration degree is high.

Description

technical field [0001] The invention relates to a transmission box integration technology, in particular to an integrated transmission box integration technology and an overall layout scheme, and belongs to the technical field of transmission box overall layout. Background technique [0002] After more than 60 years of development, my country's military engineering machinery has basically formed a relatively complete structural system, and has made considerable progress and improvement in the number and quality of models. At present, it has formed a field engineering machinery, construction machinery and support There are dozens of construction machinery equipment mainly in the three major categories of machinery, with basically complete varieties and specifications. [0003] However, my country's current military engineering machinery is far behind developed countries in terms of mobility, quick response, automation, information processing capabilities, protection capabiliti...

Problems solved by technology

[0009] The purpose of the present invention is to provide an integrated transmission box integration technology and overall layout scheme to solve the problem of low level of integration, low power density and ton power, and failure to realize double-pump and double-motor drive Control technology and first-gear low-speed small-radius steering power cycle control issues. Using a traditional two-stage planetary steering device increases the complexity of the system, increases weight and volume, and is inconvenient for high integration. On the other hand, its steering radius cannot be continuous Adjustable, resulting in poor steering dynamics of the vehicle
