Full-automatic highway-railway free conversion driving wheel

Abstract

The invention provides a full-automatic highway-railway free switching driving wheel. The driving wheel can switch between a highway mode and a railway mode. Six guide columns are mounted on a wheel hub of the driving wheel; a main driving part is fixedly connected with a wheel flange and the wheel hub through a pressing plate and a threaded column at the upper part of a hub guide column; a springbolt assembly is installed in the guide column; each flange sheet of the wheel flange is provided with a guide groove; the guide column slides in the guide groove; and two self-locking grooves are formed in one side in the guide groove, a spring bolt part of the spring bolt assembly moves into the self-locking grooves to achieve a self-locking effect, an electromagnetic clutch and a cam are sequentially installed on an output shaft of a conversion motor of the main driving part, a wheel column of the cam is matched with a cam groove, and a cam column of the cam slides in the cam groove to complete rotating motion. A problem of control complexity in a highway-railway conversion process is solved, a requirement for the compact and small structure of an AGV is met, and control over a rail transit highway-railway dual-purpose vehicle is simplified.

Description

technical field [0001] The invention relates to a fully automatic road-rail free conversion drive wheel, which belongs to the technical field of drive wheels. Background technique [0002] At present, no matter in the AGV industry or in the rail transit industry, the transformation of the road and railway environment is involved, and it is realized by adding railway guide wheels. Some railway guide wheels have power and some do not. Most of them adopt the principle of hydraulic lifting, which will inevitably require an additional hydraulic system, which not only increases the volume of the whole machine, but also increases the complexity of control. Contents of the invention [0003] In order to solve the problems mentioned in the above-mentioned background technology in the conversion process of road and iron, the present invention mostly adopts the principle of hydraulic lifting, which inevitably needs to add a set of hydraulic system, which not only increases the volume...

Problems solved by technology

[0003] In order to solve the problems mentioned in the above-mentioned background technology in the process of road-to-rail conversion, the present invention mostly adopts the principle of hydraulic lifting. This form will inevitably require an additional hydraulic system, which not only increases the volume of the whole machine, but also increases the complexity of the control. A fully automatic road-rail free switching drive wheel is proposed to meet the needs of compact and compact AGV vehicles and realize the simplification of the control of rail transit road-rail vehicles
