1.  There is a need of a flexible connection between the main frame and the wheels of the vehicle in dynamic condition that enables the relative motion between them without causing deformation to the main structure or any other components of the vehicle. 2.  A suspension system in a vehicle is needed to support the overall…

Suspension is the term given to the system of springs, shock absorbers and linkages that connects a vehicle to its wheels. Suspension systems serve a dual purpose — contributing to the car’s road holding/handling and braking for good active safety and driving pleasure, and keeping vehicle occupants comfortable and reasonably well isolated from road noise, bumps,…

Gear teeth are designed so that the number of teeth on a gear is proportional to the radius of its pitch circle, and so that the pitch circles of meshing gears roll on each other without slipping. The speed ratio for a pair of meshing gears can be computed from ratio of the radii of the pitch…

A reverted gear train is very similar to a compound gear train. They are both used when there is only a small space between the input and output shafts and large changes in speed or power are needed. A simple reverted gear train consists of two shafts each of which carry multiple compound spur gears. A…

Like a compound gear train, planetary trains are used when a large change in speed or power is needed across a small distance. There are four different ways that a planetary train can be hooked up. A planetary gear train is a little more complex than other types of gear trains. In a planetary train…

Simple Gear Train- The simple gear train is used where there is a large distance to be covered between the input shaft and the output shaft. Each gear in a simple gear train is mounted on its own shaft. When examining simple gear trains, it is necessary to decide whether the output gear will turn…

A gear train is formed by mounting gears on a frame so that the teeth of the gears engage. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping; this provides a smooth transmission of rotation from one gear to the next. •    A gear train is two or more…

First….What is torque? Torque is a twisting force- (it doesn’t do any ‘work’ itself- it is simple an application of energy). Work (or ‘stuff’) happens, when torque is applied and movement occurs. “Torque is a force that tends to rotate or turn things. You generate a torque any time you apply a force using a…

The gear ratio tells us how fast one gear is rotating when compared to another. If our input gear (10 teeth) is rotating at 5 rpms, and it is connected to our output gear (50 teeth), our output gear will rotate at 1 rpms. Why? Our gear ratio is 50:10… or 5:1 If our small gear rotates…

The gear ratio of a gear train is the ratio of the angular velocity of the input gear to the angular velocity of the output gear, also known as the speed ratio of the gear train. The gear ratio can be computed directly from the numbers of teeth of the various gears that engage to form the…
