AI Technical Summary
The existing 5-ton loader gearbox and the oil passage of the electronic control valve cannot be matched, resulting in a long design cycle and high development cost for the electronic control valve system.
A transition structure for the electronic control valve of a 5-ton loader gearbox is designed. The oil passage is connected through the gearbox gasket, transition plate and electronic control valve gasket, and locked with spring washers and bolts.
It shortens the design cycle and development cost of the electronically controlled valve system, has a simple and compact structure, low manufacturing and maintenance costs, and is reliable in use.

Abstract
Claims
1. A transition structure of an electric control operating valve of a 5-ton loader gearbox, comprising a box body (1) and an electric control operating valve (5), characterized in that, It also includes a housing gasket (2), a transition plate (3), and an electric control valve gasket (4) whose outlines match the mounting surface of the electric control valve (5); the housing gasket (2) and the transition plate (3) are provided with oil passage holes and bolt holes, the number, size, and arrangement of which correspond to the oil passage holes and bolt holes on the housing mounting surface; the electric control valve gasket (4) is also provided with oil passage holes and bolt holes, the number, size, and arrangement of which correspond to the oil passage holes on the mounting surface of the electric control valve (5). The holes and bolt holes correspond; because the oil passage on the mounting surface of the electric control valve (5) is long and narrow, the transition plate (3) cuts out the long and narrow oil passage of the electric control valve gasket (4) and connects with the oil passage hole corresponding to the mounting surface of the housing, and seals the remaining long and narrow oil passage after the electric control valve gasket (4) is cut out; the gasket (2), transition plate (3), electric control valve gasket (4), and electric control valve (5) are locked on the housing (1) by spring washer (6) and bolt (7).
