# Car Axle: Functions, Components and How it Works

An automobile is a four-wheeled vehicle with multiple interrelated parts. There are numerous types of components with distinct purposes in a vehicle.

The axle is one of the most significant components exclusive to these four-wheeled vehicles. The axle is a component of the vehicle’s drive system or is related to the vehicle’s speed.

The car’s axle is called “differential” in English, meaning “different” This indicates that this component rotates differently than the left and right tire axles when the vehicle is turning.

Axle-equipped vehicles can be recognized by their right and left tires operating at the same speed. According to conventional wisdom, the left and right axles must have distinct speeds, particularly while the vehicle is turning.

To learn more about what an automobile axle is. Below is a description of the car axle’s roles, components, and operation.

## Car Axle Function

The primary function of the car axle is to convey energy or engine power so that the vehicle can drive forward or backward.

In addition, the axle provides the difference in rotation between the right and left wheels during turns, allowing the vehicle to turn precisely.

This automobile component consists of numerous components that can turn a vehicle 90 degrees.

After changing the clutch, the car’s axle torque, initially straight from the engine, can alter to 90 degrees. Consequently, the axle of the drive wheel can rotate.

Additionally, the car axle can increase torque or torque. Due to the axle, the engine’s rotation will eventually be raised to a greater degree in the future. The power is sent to the driving axles housed within the car’s axle.

There is also a double axle whose purpose is to facilitate the movement of the car’s wheels. This axle contains two driving axles so that a vehicle can move all of its wheels.

## Car Axle Components

A car axle is composed of several components that have their respective functions. And here some of the components that can be found on the axle of the car:

### 1. Driven Pinion Shaft

Together with the pinion gear is the component known as the pinion gear shaftâ€”the driven pinion shaft functions as a rotating shaft in propeller shaft flow and rotation.

### 2. Drive Pinion Gear

This vehicle’s axle contains components with pineapple-shaped gear.

This pinion gear drive serves as a gear that transfers engine power from the propeller shaft to the car’s garden circuit.

### 3. Ring Gear

This component has a ring-like form and is relatively massive, as its name suggests. The ring gear must receive rotation from the drive pinion gear.

### 4. Spider Gear

Two spider gears are situated at a 90-degree angle from the side gear on the axle. The role of the spider gear is to serve as a turning gear, allowing the vehicle to attain a pedestal when turning.

### 5. Spider Gear Shaft

Two spider gears are situated at a 90-degree angle from the side gear on the axle. The role of the spider gear is to serve as a turning gear, allowing the vehicle to attain a pedestal when turning.

### 6. Differential Carrier

This component is also known as the differential case, which serves as a space or home to store automobile garden components.

### 7. Side Gear

The role of the side gear is to accept rotation from the spider gear, which is subsequently transmitted to the axle shaft.

### 8. Bearing Cap

The role of the bearing cap on the car axle is to secure the axle bearing to the side of the gear.

### 9. Pinion Shaft Roll Pin

A component of the car’s axle functions as a safeguard to maintain the connection between two or more components. Thus, when the vehicle turns or drives at a given speed, the axle components (especially the pinion shaft and pinion gear) remain connected (especially the pinion shaft and pinion gear).

### 10. Axle Shaft Bearing

The axle shaft bearing of a garden vehicle serves as a bearing or base for other spinning components. This component consists of two components situated on the left and right side gear of the garden car.

### 11. Axle Shaft Housing

As the axle cover, the axle shaft housing is a component of the primary axle of the vehicle. This component serves to complete the axle and axle system.

### 12. Thrust Washer

This component also called a gasket, prevents leakage at each connection when pressure is applied. With the existence of a gasket, it is possible to prevent garden oil from leaking.

### 13. Yoke

The axle component of the car functions in holding the rear universal joint and connecting the propeller shaft to the differential case.

## How Car Axle Works

The car axle serves a crucial purpose for the vehicle. Therefore, the car’s axle must be in good shape so that the vehicle can move freely. How exactly does this car axle operate?

### 1. Turning the Car

When the car turns, the inside wheels experience rotational resistance from the direction-changing front wheels.

This configuration creates a weight difference between one side gear and the other. For instance, the left wheel side gear gets heavier than the right wheel side gear.

Due to the differential weight of the side gear, the pinion gear spins during rotation. The right side gear will select a faster rotation, differentiating the right and left wheel rotations.

When the pinion gear distinguishes between two rotations, their respective rotational directions become opposing. The two pinion gears make a 90-degree angle with the side gear.

### 2. Car Running Straight

When the vehicle travels in a straight line, the rotary power created by the propeller shaft will enter the pinion driving gear.

The rotary power will be connected to the inner surface of the ring gear with other teeth.

In this configuration, the garden car causes the ring gear RPM to be lower than the pinion driving gear RPM.

Even though the ring gear’s RPM has decreased, the torque has increased. Next, the ring gear’s rotation will be sent to the differential case.

From there, the pinion shaft rests on the side of the differential case, and its ends are positioned on the two pinion gears that were previously attached to the two side gears.

The differential case’s rotational flow will proceed directly to the pinion shaft in this circumstance. Eventually, the flow will be transferred to the pinion gear and the side gear.

The pinion gear will spin around the pinion axis, causing the left and right wheels to appear more dissimilar from the rotating side.

However, because the steering wheel is in a straight position, the load on the right and left wheels appear identical. Thus, the pinion merely rotates relative to the case’s side gear.

That was a further description of the car axle that vehicle owners must understand, particularly those with four-wheeled vehicles. Hopefully, the information provided above will be of use.
