Delphi Automotive new technology

this paper mainly introduces the e-steeltm electric steering system, quadrasteertm four-wheel steering and other half axle products produced by Delphi

the half axle range produced by Delphi includes a small output of 1100 to 6000 nm and a maximum of 1600 to 7800 nm, including a high-quality small universal joint for a specific maximum torque and an external angle increased universal joint for enhanced steering angle and stroke capacity. It can meet various application requirements, including reliability, mass reduction, fuel efficiency, durability and performance standards. The expertise based on nearly 40 years of experience enables design engineers and customer engineers to work together to solve the relationship between the axle shaft and the entire vehicle, especially the system problems between the chassis and the powertrain

electric steering systems

e steer electric steering system

the electric steering system (e steer) produced by Delphi Automotive electronic components company is a completely electronically operated system with an independent engine. It saves the power steering hydraulic pump, hose, hydraulic fluid of the traditional hydraulic system, as well as the engine drive belt, pulley, etc. Instead, use the electric energy of the motor to provide rapid steering power. The electric steering system is supplied to customers as a module, which simplifies the production process and reduces assembly time

the sensor detects the driving speed of the vehicle and the tensile strength of the rock on the steering axle shaft, which can be divided into two types of dynamic torque: direct connection method, and provides the system variables and input data to an electronic control module. The module determines the direction and strength of the auxiliary steering, sends commands to the engine through the controller, changes the transmission torque, and drives the gear unit to produce the required steering torque

electric auxiliary device

set the parameters of the system through the electric auxiliary device located on the steering column or bracket, so that the electric steering system (e steer) is suitable for vehicles of all sizes: from small cars to trucks of all sizes. Whether the electric auxiliary device is installed on the steering column or bogie, the controller of the electric steering system can be integrated with the system or remotely positioned, which enables designers to make better use of the existing space

bogie auxiliary device

bogie auxiliary device is a system that can be upgraded, which is suitable for medium-sized cars and various types of trucks. This upgraded feature can enable automobile manufacturers to make better use of the existing mechanical hardware working for 12 volt systems, and can also be applied to the future 42 volt application systems

using an independent engine design can reduce additional losses, improve acceleration times, and enhance reliability and safety - even after turning off the engine, mechanical steering can still play a role. Compared with the traditional hydraulic system, the fuel efficiency can be increased to 4%

quadraster four wheel steering

the four wheel steering system (quadraster) produced by Delphi Automotive electronic components company is composed of a traditional front wheel steering system and a rear wheel electric steering system, which includes a wheel alignment sensor, a speed sensor and a central electronic control module

the system controls the movement direction of the rear wheel electronically: when driving at low speed, the steering direction of the rear wheel is opposite to that of the front wheel; When the car is running at medium speed, the rear wheels remain vertical or moderate; When the car is moving fast, the rear wheels are in the forward phase, and the steering direction is the same as that of the front wheels

typical application

four wheel steering system is especially suitable for standard size trucks, vans and sports vehicles

performance advantages

quadraster four-wheel steering system can help reduce the turning radius of the car at high speed and greatly improve the stability of the car at high speed, especially when driving with a trailer.
