Abstract
The utility model relates to an eccentric fuel-supply angle automatic advancer, which is a device to automatically regulate the fuel-supply angel in the fuel supply system of a diesel engine. The utility model is characterized in that the scheduled running tracks and the working principle are mainly realized by a hinge four links mechanism comprising a pair of double eccentric wheels and the centrifugal force of a flyweight, and the complicated hinge four links mechanism comprising a flyweight, an arc piece, a spring, etc. In prior art is replaced. Compared with prior art, the utility model has the advantages of reasonable structure, long service life, light wear, good working performance, small working noise, manufacturing convenience, etc. and consequently the utility model can be extensively used in the diesel engine manufacturing to compatibly manufacture diesel engines, in particular to compatibly manufacture various high-speed diesel engines.
Description
The utility model relates to a kind of device in the IC engine fuel supply system, says it is to be used for a kind of eccentric oil supply angle automatic advancing device that the diesel engine fuel oil supply system is adjusted oil supply angle in more detail.
The oil supply angle automatic advancing device that uses in the known diesel engine belongs to and flies the piece centrifugal structure, and its intended operation track and working principle are flown by kink four bar linkage that flies that piece, arc piece and spring etc. form and utilization mainly that piece centrifugal force realizes.This apparatus structure is comparatively complicated, line contact high-amplitude, restorative difference and working life are short, and the noise that occurs during this in addition device busy is also bigger.
The purpose of this utility model provide a kind of rational in infrastructure, manufacturing easily, favorable working performance and little two planes that have of operating noise turn round the eccentric oil supply angle automatic advancing device of the width of cloth by a narrow margin.
The utility model adopts and flies the centrifugal and two eccentric revolution width of cloth structures of piece, the kink four bar linkage that its intended operation track and working principle mainly are made up of a pair of double eccentric wheel and utilizing flies that piece centrifugal force realizes, more specifically be achieved in that when tie-plate of the present utility model is driven in rotation, all parts of the present utility model all rotate by sense of rotation with it, when reaching certain rotating speed, flying piece outwards separates under action of centrifugal force, at this moment, be fixed on the piece pin that flies that flies on the piece and drive large eccentricity wheel and small eccentricity wheel, small eccentricity wheel and the drive pin that is fixed on the tie-plate, relatively rotate several angle, driving driven disc at this while large eccentricity wheel is that the center turns an angle forward along its sense of rotation with respect to tie-plate with the fuel injection camshaft, to realize that oil supply angle shifts to an earlier date automatically.Two pairs of springs are pressed in two two ends that fly piece respectively, when the utility model rotating speed reduces, the pressure of spring forces two to fly piece to drawing in together, can make driven disc is that the center turns an angle with respect to contrary its sense of rotation of tie-plate with the fuel injection camshaft, reduces automatically to realize the fuel supply advance angle degree.When the utility model under a certain rotating speed during steady running, balance each other by flying restoring moment and Injection Pump resisting moment sum that moment that piece centrifugal force produced and spring produced, thereby make drive end of the present utility model and injection pump cam axle head keep a needed angle, to reach the purpose of adjusting fuel supply advance angle.
The kink four bar linkage that the width of cloth is turned round on the plane that the utility model is formed with two double eccentric wheels has by a narrow margin replaced forming complicated high-amplitude kink four bar linkage by flying piece, arc piece and spring etc. in the known technology, therefore the utility model compared to the prior art, rational in infrastructure, light abrasion, long service life, favorable working performance are arranged and characteristics such as operating noise is little and manufacturing is easy, so, the diesel engine but extensive use diesel engine manufacturing industry forms a complete production network, various high-speed diesel engines are specially adapted to form a complete production network.
Below in conjunction with drawings and Examples the utility model is described in further detail.
