Abstract
The invention discloses a hunting-preventing device for a locomotive, relating to a hunting-preventing device for preventing fluctuation of the revolving speed when a 4D type internal-combustion engine runs at a low speed in a no-load way. The hunting-preventing device for the locomotive mainly aims at solving the problem that when the 4D type internal-combustion engine runs at a low speed in a no-load way, since a speed regulator matches the internal-combustion engine, making the total resistance of an oil supply draw bar of the internal-combustion engine big, the work capacity of the speed regulator at a low revolving speed can not be balanced with the total resistance of the oil supply draw bar, and the hunting occurs. The hunting-preventing device, wherein one end of a guide pin is fixed on an engine body base and other end thereof is movably connected with a draw bar base; the guide pin is provided with a spring, wherein the two ends of the spring are respectively connected with the engine body base and the draw bar in a contact way; the engine body base and the draw bar base are respectively fixed on a fuel pipe cassette on the ninth cylinder of the internal-combustion engine and the draw bar. The hunting-preventing device makes use of the spring to buffer changes on the draw bar under a stress, and the draw bar to control the oil supply so as to reduce the total resistance of the oil supply draw bar, and lowers the revolving speed hopping frequency to achieve constant revolving speed change and avoid occurrence of hunting for the locomotive.
Description
Technical field
The present invention relates to the anti-tourist bus device of locomotive, relate to 4D type internal-combustion engine specifically when low speed no-load running, prevent the anti-tourist bus device of the fluctuation of speed.
Background technique
When the low speed no-load running, the tourist bus of 4D type locomotive internal-combustion engine is difficult to solve for 4D type internal-combustion engine, and reason is the matching problem of speed regulator and internal-combustion engine; The drag overall of 4D type locomotive internal-combustion engine fuel feeding pull bar is big, the slow-revving ability to work of speed regulator can't with fuel feeding pull bar drag overall balance, make fuel feeding non-constant; And make the fluctuation of low speed no-load speed, and, the fluctuation of low speed no-load speed belongs to tourist bus when surpassing 20r/min, and 4D type internal-combustion engine tourist bus is a difficult problem of each system shop always; General solution is that the needle-valve of speed regulator is adjusted; Perhaps change speed regulator, owing to the matching reason of speed regulator and internal-combustion engine, the situation of tourist bus still can not be resolved;
The situation of tourist bus does not also have other effective solution at present.
The objective of the invention is to above-mentioned deficiency, and propose a kind of when making the no-load running of internal-combustion engine low speed, the rotating speed change is constant, simple in structure, the internal combustion locomotive of easy accessibility is prevented the tourist bus device.
Technical solution of the present invention is: an end of the guide finger of the anti-tourist bus device of internal combustion locomotive is fixed on the body seat, and the other end and draw-bar seat flexibly connect, and spring is housed on guide finger, and contact is connected with draw-bar seat with the body seat respectively at the two ends of spring; Body seat and draw-bar seat are separately fixed on the fuel pipe deck and pull bar at internal-combustion engine the 9th cylinder place.
Draw-bar seat described in the technical solution of the present invention is made up of two orthogonal panels, and the vertical plane perpendicular with the internal-combustion engine upper connecting rod is provided with pilot hole, and another vertical plane is connected with the pull bar of internal-combustion engine.
It is that guide finger is contained in the pilot hole on the draw-bar seat that one end of the guide finger described in the technical solution of the present invention and draw-bar seat flexibly connect, and this end of spring withstands on the draw-bar seat outer side surface.
Main feature of the present invention is: (one) adopts the mode of pull bar control fuel feeding, reduces the drag overall of fuel feeding pull bar, to reduce the frequency that rotating speed is beated, changes constant thereby reach rotating speed; (2) utilize the characteristic of spring to energy snubber, an end of spring is fixed on the body, the other end of spring and pull bar interlock realize the stressed variation of spring buffer pull bar, thereby have avoided the generation of internal combustion locomotive tourist bus; Compact structure of the present invention connects simply, and easy accessibility has been practiced thrift the cost that repairs, and has shortened the cycle of repairing, and through on probation to installing on the internal combustion locomotive of many 4D vehicles, the tourist bus phenomenon all disappears.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, the anti-tourist bus device of internal combustion locomotive is made up of guide finger 3, spring 4, body seat 1 and draw-bar seat 2, and spring 4 is installed on the guide finger 3; One end of guide finger 3 is fixed on the body seat 1 with jam nut, and the other end of guide finger 3 and draw-bar seat 2 flexibly connect, and promptly guide finger 3 is contained in the pilot hole on the draw-bar seat 2; Draw-bar seat 2 is made up of two orthogonal panels; A vertical plane of draw-bar seat 2 is provided with pilot hole, and it is perpendicular that draw-bar seat 2 has the vertical plane and the pull bar on the internal-combustion engine of pilot hole, and spring 4 is installed between body seat 1 and the draw-bar seat 2; One end of spring 4 withstands on the body seat 1, and the other end withstands on the draw-bar seat 2; Body seat 1 of the present invention is installed on the fuel pipe deck at internal combustion engine body the 9th cylinder place, is fixed on the IC engine airframe with the pipe clamp seat, and another vertical plane of draw-bar seat 2 is connected with the pull bar on the internal-combustion engine.
Working principle: during internal combustion engine start,, give constant force of fuel feeding pull bar, shorten the explosion time of internal combustion engine start to the fuel feeding direction through the back pressure of spring 4; After the internal-combustion engine outburst, this constant elastic force has been eliminated the total backlash of fuel feeding pull bar, and has reduced the drag overall of fuel feeding pull bar, makes speed regulator and fuel feeding pull bar equalising torque, alleviates or elimination internal-combustion engine tourist bus phenomenon thereby reach.
