Problems solved by technology

Theoretically, these three volume speed regulating circuits can all be used in mechanical-hydraulic hybrid transmissions, but if the above circuits are used as hydraulic branches, the transmission of power flow is always unidirectional, and the total output speed of the hybrid transmission is only It "increases" the speed of the hydraulic transmission branch on the basis of the output speed of the mechanical transmission branch, and the ability to expand the speed range is limited.

Description

Technical field [0001] The invention belongs to the technical field of mechanical and hydraulic transmission and control, and relates to a mechanical hydraulic hybrid stepless speed change device using secondary components. Background technique [0002] Hydraulic transmission has the advantages of light weight, small size, high power density, easy to realize stepless speed regulation and automatic control, but it also has disadvantages such as low transmission efficiency, especially in high-speed and low-speed transmission conditions. The shortcomings are more prominent. Gear mechanical transmission has the advantages of accurate and reliable transmission movement, constant instantaneous transmission ratio, compact structure, large transmission ratio, high transmission power and high transmission efficiency, but it is not easy to realize automatic transmission, let alone stepless transmission. In the operation of medium and large construction machinery, the transmission system o...
