专利汇可以提供Robot locomotive for classifying rolling stocks专利检索，专利查询，专利分析的服务。并且A robot locomotive is disclosed which is adapted to be releasably coupled to a freight car which is approaching at a relatively lower speed to the head of a classifying network in a yard or which is stopped at the head so as to accelerate and push it off on a desired track. Upon a main frame supported by wheels riding on guide rails laid inside a railway track are mounted a hydraulically operated pusher assembly adapted to forcibly press against the flanges of the first wheel of a freight car and a hydraulic brake system. In response to the external signals an electronic controller controls various hydraulic control valves in a hydraulic controller so as to control the hydraulically operated pusher assembly and brake system.，下面是Robot locomotive for classifying rolling stocks专利的具体信息内容。

权利要求

1. A hydraulically operated robot locomotive for pushing rolling stocks comprising a main frame supported on wheels so as to travel along a guide track; a power source mounted upon said main frame and comprising a hydraulic pump, means for driving said hydraulic pump, and a reservoir for working hydraulic liquid; a traction system comprising a plurality of hydraulic motors which are driven by hydraulic liquid under pressure supplied from said power source; a hydraulic control system including hydraulic control valves for controlling said power source and said traction system, an electronic control system for controlling said hydraulic control valves in said hydraulic control system in response to control signals applied from the exterior of said robot locomotive; a hydraulic brake system for applying mechanical brake to said wheels of said main frame; and a hydraulic rolling stock pusher assembly adapted to releasably couple said robot locomotive to a rolling stock, whereby said robot locomotive may push the rolling stock.

2. A robot locomotive as defined in claim 1 further comprising an accumulator mounted on said main frame for accumulating therein working liquid under pressure and adapted, in response to a control signal, to supply working liquid under pressure to said hydraulic motors, said hydraulic brake system, and said hydraulic rolling stock pusher assembly through said hydraulic control system.

3. A robot locomotive as defined in claim 2 wherein said traction system further comprises driving pinions which are drivingly coupled to said hydraulic motors and are adapted to engage with racks laid on the side of a track of rolling stock, whereby said robot locomotive may be driven without slippage.

4. A robot locomotive as defined in claim 3 wherein said hydraulic rolling stock pusher assembly comprises collision preventive means each of which comprises a collision preventive valve, and a lever operatively coupled to said collision preventive valve and said hydraulic rolling stock pusher assembly, whereby a wheel of a rolling stock pushes said lever in case of an erratic operation of said pusher assembly to cause the same to retract to the inoperative position.

5. A robot locomotive as defined in claim 1, wherein said hydraulic motors are of the variable-displacement type.

6. A fluid-operated robot locomotive for pushing rolling stock, comprising a frame supported on wheels for travel along a guide track; a power source mounted on said frame; a traction system coupled with said wheels and driven by said power source; an operations control system for controlling said power source and said traction system; an electronic control system, including detecting means for detectiNg the proximity of rolling stock, for controlling said operations control system in response to control signals applied from the exterior of said robot locomotive; a brake system for applying mechanical braking force to said wheels of said frame; and a rolling stock pusher assembly adapted to releasably couple said robot locomotive to an item of rolling stock, whereby said robot locomotive may push the rolling stock.

7. A robot locomotive as defined in claim 6, wherein said rolling stock pusher assembly comprises collision preventive means for preventing collision between said robot locomotive and rolling stock.
