Embodiment Construction

[0009] As shown in the figure, the inner ring of the auxiliary support bearing 3 of the present invention is fixed on the lock nut 2, and the outer ring is mounted on the planet carrier 4 in the planetary mechanism with clearance fit, and there is a certain amount of floating. The auxiliary transmission input gear (sun gear) 1 is directly integrated with the second shaft of the main transmission (or fixed on the second shaft of the main transmission through splines); in the planetary mechanism, the planetary gear 5 is vacantly sleeved on the planet through a needle bearing. On the wheel shaft 6, the planet wheel shaft 6 is directly supported on the planet carrier 4, one end of the planetary mechanism assembly is supported on the rear housing 10 through the cylindrical roller bearing 9, and the other end is meshed with the sun gear 1 through the planetary wheel 5; at the same time, the support seat 7 floats On the deep groove ball bearing 8, there is a gap between the outer ring...

Abstract

The invention discloses an auxiliary supporting structure for a planetary mechanism assembly of a planetary transmission pair speed changer of an automobile speed changer. A bearing is arranged to assist in supporting the planetary mechanism assembly, so that load unbalance caused by backlashes of a planetary gear and a sun gear, part processing error of a planetary mechanism and the like is eliminated effectively and early damage of parts is avoided. An auxiliary speed changer serves as a combined multi-gear speed changer with a planetary transmission structure. The auxiliary supporting structure has a wide popularization prospect in medium and light commercial vehicles.

Description

technical field [0001] The invention discloses an auxiliary support structure for a floating bearing of a planetary mechanism assembly in an auxiliary transmission adopting planetary transmission technology in an automobile combined multi-speed transmission, and belongs to the technical field of automobile transmission. Background technique [0002] At present, the use of combined multi-speed transmissions for international and domestic commercial vehicles has become more and more popular. In addition, more and more auxiliary transmissions adopt planetary transmission structure technology. Due to the particularity of the cantilever structure of the planetary mechanism assembly, foreign products have high requirements on the shape and position tolerance and matching accuracy of the planetary mechanism assembly parts in the planetary structure auxiliary transmission. However, when used in medium and light commercial vehicle transmissions, due to the constraints of manufacturin...
