Abstract

The invention provides a linear shaft high power density differential assembly which comprises a linear shaft differential case (1), wherein an inner cavity of the differential case (1) is connected with a linear shaft (6); the two ends of the linear shaft (6) are connected with planet bevel gears (8); the inner cavity of the differential case (1) is connected with half shaft bevel gears (4) respectively; strengthening rings (4b) connected with half shaft bevel teeth (4a) are arranged on the large end surfaces of the half shaft bevel gears (4); and the strengthening rings extend from tooth bottoms (4c) upwards to positions, close to the tops, of the upper parts of the bevel teeth (4a). Strengthening rings (8b) connected with planet bevel teeth (8a) are arranged on the large end surfaces of the planet bevel gears (8) and extend from tooth bottoms (8c) upwards to halves of the bevel teeth (8a). The assembly has the following advantages that: 1, with the adoption of the linear shaft differential case, light weight of a differential is achieved, and the production efficiency is improved; and 2, the strengthening rings (ribs) are added at the large ends of the planet gears and the half shaft gears, the strength of the planet gears and the half shaft gears is improved, and high power density is achieved.

Description

Technical field: [0001] The invention relates to the field of auto parts, in particular to an inline shaft type high power density differential gear assembly for 3-ton series rear axles. technical background: [0002] The differential assembly mainly realizes the phenomenon of differential speed caused by the inconsistency of the movement speed of the wheels on both sides during the turning process of the car. At present, the differential assembly in the field of the 3-ton rear axle is a cross-shaft differential housing assembly: the differential housing is divided into two parts, the left and the right housing, which are connected together by bolts and nuts. The assembly time is long, the body is large, and the load capacity is high. General; while the one-line shaft differential shell is a whole, without the connection of bolts and nuts, the assembly time is short, the size is small, and the load capacity is high. However, due to the reduction in volume of the existing in...
