Double drive axle capable of achieving lifting and driving of rear axle

Abstract

The invention discloses a double drive axle capable of achieving lifting and driving of a rear axle. The double drive axle is composed of an intermediate axle assembly (50) and a rear axle assembly (60) and is characterized in that a through shaft (1), an intermediate axle active cylindrical gear (8), an inter-shaft differential device rear half shaft wheel (9), an input shaft (10), a rolling bearing (12), an intermediate axle slave cylindrical gear (13), an intermediate axle active bevel gear (14), an intermediate axle slave bevel gear (15), an intermediate axle left half shaft wheel (16), an intermediate axle right half shaft wheel (17), an intermediate axle left haft shaft (18), an intermediate axle right haft shaft (19) and a through shaft flange (21) constitute a power system of the intermediate axle assembly (50). A return spring (2), a shifting fork (3), a shifting fork shaft (4), a piston (5), a cylinder (6) and a meshing sleeve (7) constitute a power control system, transmitting power to the rear axle assembly (60), of the intermediate axle assembly (50). By controlling consolidation and disconnection of the through shaft (1) and the inter-shaft differential device rear half shaft wheel (9), an all-wheel-drive function of the whole vehicle drive axles can be achieved, and the situation that under the condition of no-load or light load of a vehicle, rear axle power transmission is disconnected, and a lifting function of the rear axle is achieved can be realized.

Description

[0001] Technical field: [0002] The invention relates to the technical fields of automobile axles, gear reducers, etc., and specifically relates to a dual drive axle capable of lifting and driving a rear axle. [0003] Background technique: [0004] The automobile axle is responsible for carrying, traveling, braking, increasing torque, transmitting torque and reasonably distributing the functions to the left and right wheels of the vehicle. When the car is fully loaded, the axles need to provide large load and high torque, so as to realize the distributed load of the vehicle, reduce the damage to the road surface, start smoothly, and run normally. At this time, all drive axles of the vehicle need to participate in the load and drive; When the return journey is carried or the goods carried are light throws, the carrying and driving capacity of the drive axle designed according to the maximum load mass of the vehicle will be extremely excessive, and due to the large number of dr...
