Problems solved by technology

Taking an 8×8 vehicle as an example, if the vehicle needs to achieve full motion coordination, it needs 4 inter-wheel differentials and 3 inter-axle differentials; it is assumed that all of them are realized with open differentials, such as a certain wheel in The loss of adhesion on special road surfaces will cause all wheels to lose power; although differentials with locking devices (including e

Abstract

The invention belongs to the technical field of power transmission, and particularly relates to a vehicle hybrid power driving system. According to the technical scheme of the multi-axle multi-wheel vehicle hybrid electric driving system, in a mechanical drive section, an engine (1) and a gearbox (3) are longitudinally arranged, an elastic coupler (2) is arranged between the engine and the gearbox, a transfer case (4) is connected to the rear side of the gearbox (3), and the transfer case (4) conducts power distribution and distributes the power into axles through a drive axle; in a dynamic drive section, a wheel edge drive motor (8) and a double-gear gearbox (7) are combined to drive the axles, the wheel edge drive motor (8) is connected to a power management system (21), and the power management system (21) is connected with a battery pack (22) and the gearbox (3). According to the multi-axle multi-wheel vehicle hybrid electric driving system, an inter-axle differential mechanism and an inter-wheel differential mechanism are omitted, the structure of the driving system is simplified, a transmission chain is shortened, and power distribution is flexible.

Description

Technical field [0001] The invention belongs to the technical field of power transmission, and specifically relates to a vehicle hybrid drive system. Background technique [0002] Multi-axle drive vehicles have reasonable axle load distribution, strong power and passability, and are widely used in heavy-duty wheeled vehicles and military wheeled vehicles. As the requirements for vehicle maneuverability and handling stability increase, the need for flexible distribution of power between the axles and between the wheels of multi-axle drive vehicles is more urgent. The flexible distribution of power between the axles can make full use of the adhesion of the road surface to improve the acceleration ability; the power distribution between the wheels can not only slip and get out of trouble, but also realize the directional distribution of torque between the wheels, improve the yaw acceleration of the vehicle, and improve the cornering process Maneuverability. [0003] Traditional mult...
