The invention relates to an internal gear pump power transmission device of an automobile hydraulic retarder, which belongs to the technical field of truck manufacturing and comprises a pump seat plate, an outer gear ring, an inner gear ring, a transition sleeve, a power shaft and an aluminum sealing plate. When the retarder works, the power shaft drives the inner gear ring and the outer gear ring to rotate in a meshed mode, and oil pumping is achieved. Oil films are formed between the front ends of the outer gear ring and the inner gear ring and the pump seat plate, oil films are also formed between the rear ends of the outer gear ring and the inner gear ring and the aluminum sealing plate, and liquid friction is achieved. Due to the fact that an inner spline of the inner gear ring and an outer spline of the transition sleeve can axially move to a certain degree, under the action of an oil film, it is guaranteed that gaps between the front ends of the outer gear ring and the inner gear ring and a pump seat plate and gaps between the outer gear ring and the inner gear ring and an aluminum sealing plate can be automatically adjusted; therefore, liquid friction is achieved, and damage caused by dry friction is avoided. The internal gear pump power transmission device of the automobile hydraulic retarder is simple in structure, low in manufacturing cost and capable of being widely applied to trucks provided with the hydraulic retarder of the internal gear pump.
本发明涉及一种汽车液力缓速器内啮合齿轮泵动力传动装置,属于载货汽车制造技术领域,本发明包括泵座板、外齿圈、内齿圈、过渡套、动力轴和铝密封板;缓速器工作时,动力轴带动内齿圈与外齿圈啮合转动,实现泵油。在外齿圈和内齿圈的前端与泵座板之间形成油膜,外齿圈和内齿圈的后端与铝密封板之间也形成油膜,实现液体摩擦。由于内齿圈的内花键与过渡套外花键之间可以有一定的轴向移动,在油膜的作用下,保证了外齿圈和内齿圈的前端与泵座板之间的间隙、及外齿圈和内齿圈与铝密封板之间的间隙可以自动调整;从而实现液体摩擦,不会发生干摩擦而损坏。这一种汽车液力缓速器内啮合齿轮泵动力传动装置结构简单,造价低廉,可以广泛应用于安装了内啮合齿轮泵的液力缓速器的载货汽车。
