Title (EN) HIGH-PRESSURE FUEL PUMP DRIVING STRUCTURE
(FR) STRUCTURE D'ENTRAÎNEMENT DE POMPE À CARBURANT HAUTE PRESSION
(ZH) 一种高压燃油泵驱动结构
Abstract:
(EN) A high-pressure fuel pump driving structure for an engine, comprising: a skew gear (5) with an internal spline; a sleeve (4) with an external spline; a sliding sleeve (7); and a fixed sleeve (9); the sleeve (4) is mounted fixedly on a pump shaft of the high-pressure fuel pump, and the fitting clearance of the external spline of the sleeve (4) and the internal spline of the skew gear (5) enables the skew gear (5) to slide relative to the sleeve (4) along axial direction. The sliding sleeve (7) and the fixed sleeve (9) are coaxially sleeved together and can slide relative to each other axially. One end of the sliding sleeve (7) is propped against the skew gear (5). A pre-compressed spring (8) is provided between the sliding sleeve (7) and the fixed sleeve (9). The structure is capable of avoiding the axial force produced by driving the skew gear, thereby being more applicable for high-pressure fuel pump and reducing noise.
(FR) L'invention porte sur une structure d'entraînement de pompe à carburant haute pression pour un moteur, laquelle structure comprend :un engrenage hélicoïdal (5) ayant une cannelure interne; un manchon (4) ayant une cannelure externe; un manchon coulissant (7); et un manchon fixe (9); le manchon (4) est monté de façon fixe sur un arbre de pompe de la pompe à carburant haute pression, et l'espacement d'adaptation de la cannelure externe du manchon (4) et de la cannelure interne de l'engrenage conique (5) permet à l'engrenage conique (5) de coulisser par rapport au manchon (4) le long d'une direction axiale. Le manchon coulissant (7) et le manchon fixe (9) sont manchonnés de façon coaxiale l'un avec l'autre et peuvent coulisser axialement l'un par rapport à l'autre. Une extrémité du manchon coulissant (7) est appuyée contre l'engrenage hélicoïdal (5). Un ressort pré-comprimé (8) est disposé entre le manchon coulissant (7) et le manchon fixe (9). La structure est apte à éviter la force axiale produite par l'entraînement de l'engrenage hélicoïdal, devenant ainsi plus applicable à une pompe à carburant haute pression, et à réduire ainsi le bruit.
(ZH) 一种发动机高压燃油泵驱动结构,包括:具有内花键的斜齿轮(5);具有外花键的套管(4);滑套(7);固定套(9);套管(4)固定安装在高压燃油泵的泵轴上,套管(4)的外花键与斜齿轮(5)的内花键间隙配合以使得斜齿轮(5)在轴向方向上能相对套管(4)滑动,滑套(7)与固定套(9)同轴套装在一起并能轴向相对滑动,滑套(7)的一端抵靠在斜齿轮(5)上,滑套(7)与固定套(9)之间设置预压紧的弹簧(8)。该结构能避免斜齿轮驱动所产生的轴向力,从而更适合于高压燃油泵,并降低噪音。
