Background
A more recent working prototype of the HEV was built by Victor Wouk and earned him the title as the “Godfather of the Hybrid”. Wouk installed a prototype hybrid drivetrain into a 1972 Buick Skylark provided by GM. In 1989, Audi produced its first iteration of the Audi Duo (or Audi 100 Avant duo) experimental vehicle,…

Introduction of Hybrid Cars
Introduction A hybrid vehicle (HEV) is a type of automobile which has a conventional power system with an energy storage system (RESS). Mass production of these vehicles has been taking time due to charge time taken by regenerative braking.

Essential Components of an EPS System
EPS system designs have various components as: 1. Electric motors Electric motors are the most common electro-mechanical actuator in automobiles. Virtually every pump, fan and positioner in an automobile employs an electric motor. A typical automobile has about 25 electric motors and this number is growing with each new model. Luxury vehicles can have more…

Electric Power Steering
Electric Power Steering Electric Power Steering (EPS) is a full electric system, which reduces the amount of steering effort by directly applying the output from an electric motor to the steering system. It can solve the problems associated with hydraulic power steering [4]. Working of EPS The electronic control unit (ECU) of EPS analyzes the assisting…

Dynamic Tooth Load
The approximate allowance for the analysis of dynamic loading effect can be calculated by using the velocity factor. The dynamic loads on the tooth can be due to the inaccuracies and irregularities of the tooth spacing and tooth profiles respectively. Along with that, the deflections of gear teeth under external loading can also cause dynamic…

General Design of Hydraulic Power Steering Systems
In the Figure below, a sketch of a HPAS system is depicted that shows pump, valve assembly, rack and the hydraulic cylinder. The most important part is the valve assembly having torsion bar in the core of the valve. The function of this bar is to activate the valve and at the same time transfer the…

Components of Hydraulic Power Steering
The hydraulic pump is used to convert mechanical energy into hydraulic energy. The mechanical action of the pump takes the fluid from the reservoir in to the pump by producing a partial vacuum. This action also forces the fluid in the pump to go into the hydraulic system. 1. Types of pumps: 2. Hydraulic line:…
