A torque vectoring differential

Abstract

The invention discloses a torque guide differential. The power output of half shafts on the two sides of the same axle is regulated, so that a vehicle can turn more easily and safely. The torque guide differential consists of two planetary gear sets sharing a planetary carrier, wherein the planetary carrier is connected with a differential case; a shaft and gears in key connection with the two ends of the shaft form a group, and are arranged on the differential case through bearings and holes matched with the bearings in the differential casing, the gear at one end is meshed with a gear in key connection with a sun gear in the planetary gear set on the same side, and the gear at the other end is meshed with a gear ring in the planetary gear set on the other side; for the other group of shaft and gears, the gear in key connection with the sun gear in the planetary gear set on one side and the gear ring in the planetary gear set on the other side are connected in the opposite direction in the same way.

Description

[0001] Technical field: [0002] The invention relates to a differential gear capable of separately adjusting the power output of half shafts on both sides of the same bridge. [0003] Background technique: [0004] When the front-drive vehicle is turning, due to the effect of the center of gravity and centrifugal force of the vehicle, the vehicle’s trajectory is often greater than the actual steering angle, that is, understeer; while the direction of the rear-drive vehicle and the steering direction of the front wheel form a thrust angle when the rear-drive vehicle is in a curve, It is easy to cause the vehicle to oversteer, and even cause unconscious tail flicking, which puts the vehicle in a relatively dangerous driving state and is prone to accidents. However, a vehicle equipped with this type of differential applies more driving force to the outer wheel of the same bridge through the differential when driving in a curve, thereby generating a thrust inward to offset a part ...

Problems solved by technology

At present, this type of torque-oriented differential mostly controls the torque output of the axle shafts on both sides of the same bridge in the form of an electronically controlled friction clutch; due to various sensing, control, and actuators, the structure of this type of differential Complicated, bulky, and costly, it is mostly used in niche models such as large high-end SUVs and high-end sports vehicles
