Problems solved by technology

For example, since the B-ISG is directly connected to the engine, the engine must be turned to start, thus causing additional losses
In addition, the use of the motor as a B-ISG creates limitations on the additional functions of the vehicle

Embodiment Construction

[0016] exist figure 1 In , a vehicle powertrain 100 in the form of a gearbox is shown. The gearbox 100 is arranged in a vehicle 10 having a front axle 12, a rear axle 14 and an engine 16 for driving the gearbox 100 through a transmission (not shown).

[0017] The transmission 100 has an input shaft 102 connected to the engine 16 , a rear output shaft 104 and a front output shaft 106 . The front output shaft 106 is arranged non-coaxially with respect to the rear output shaft 104 ; the front output shaft 106 is connected to the input shaft 102 through a chain transmission mechanism 110 . The input torque is transmitted to the center differential 120, which has a first output and a second output, the first output is the rear output shaft 104, the second output is the drive side of the chain drive 110, therefore, the second The output is connected to the front output shaft 106 . The front output shaft 106 drives the front axle 12 and the rear output shaft 104 drives the rear ax...

Abstract

A vehicle powertrain (100) is provided, the vehicle powertrain (100) includes a differential (120) having an input (102), a front output connected to a front axle (12) (106) and the rear output (104) that is connected to the rear axle (14). The vehicle powertrain (100) further includes an actuator (130) configured to control operation of the differential (120) between a first mode and a second mode, at In said first mode, said front output (106) is disconnected from said input (102), in said second mode said front output (106) is connected to said input (102).

Description

technical field [0001] The present invention relates to a vehicle powertrain, and more particularly, the present invention relates to a vehicle powertrain having a gearbox. Background technique [0002] Due to increasingly stringent legislation in most parts of the world, there is an increasing need to reduce carbon dioxide (CO2) emissions from passenger vehicles. The increased need to reduce losses, combined with the increased need to increase functionality and reduce cost, has created a need for new drivetrain technologies. Nowadays, more and more vehicles are equipped with a power transmission separation system to reduce the loss of the all-wheel drive system (AWD-System). Disadvantages of these systems are that they tend to be costly and that losses in disengaged (two-wheel drive (2WD)) mode are not fully utilized, mainly due to higher clutch drag. [0003] In addition, driven by CO2 regulations, more and more vehicles are equipped or will be equipped with mild hybridi...
