Abstract

Traction is very important for the operation of the vehicle. Vehicles with high power to weight ratio sometimes struggle to gain enough traction to use all the power effectively. From this, it should be apparent that a need exists for an apparatus and system that can improve/ offer high traction to vehicle on demand. This system can be used to provide traction that can help a great deal with acceleration, braking and handling. The, design of the TIS includes actuating mechanisms and computer based control unit mounted on the vehicle as described in the complete specification. This system using actuating mechanism, exerts pressure on wheels which in turn provide high traction between wheels and the track's surface. This increase in traction is highly effective for torque utilization, acceleration, braking and handling of the vehicle. Therefore, I conclude that such a system can be used as a traction improvement system which can significantly increase the traction available which in turn will help in improving the torque utilization, acceleration, braking and handling of the vehicle.

Description

Traction Improvement System (TIS)

BACKGROUND

Traction is very important for the operation of vehicle. Regardless of. how much power is generated by an onboard motor or how much energy is stored in an onboard power supply, the only way to utilize that power to propel the vehicle is to convert that power into a force that moves the vehicle. The magnitude of acceleration force that a vehicle can achieve is directly proportional to the tractive force that is achieved by the vehicle.

In other words, the tractive force available to a vehicle greatly influences the ability of the vehicle to do work (i.e., move the vehicle).

A significant loss of the tractive force can be observed in vehicles tha .are light weight. This may lead to ineffective use of car's torque or power output.

In a competitive world where a split-second difference can help someone lose or win a race, a technology that can overcome the above-mentioned shortcomings, can be of great significance.^'

SUMMARY

From the foregoing discussion, it should be apparent that a need exists for an apparatus and system that can improve/ offer high traction to vehicle on demand.

This system can be used to provide traction that can help a great deal with acceleration, braking and handling.

Problems addressed

1- Lack of tractive force in any vehicle, mostly light weight vehicles, light. weight- high power vehicles, eg- modern supercars, super bikes, Fl cars. 2- High lack of traction when the vehicle is accelerating from standstill. This is because when moving, the significant tractive force attained by the vehicle is due to the air flowing over the vehicle which is not there when the vehicle is at rest.

3- Lack of tractive force leading to ineffective torque utilization.

4- Lack of tractive force and ineffective torque utilization leading to ineffective acceleration.

5- Lack of traction leading to ineffective. braking.

6- Lack of tractive force and ineffective torque utilization leading to ineffective handling.

Inspiration

Humans and other animals accelerating from standstill.

It can be observed that when Humans or other animals accelerate, they not only exert thrust backwards to accelerate themselves in the forward direction but also exert thrust downwards. This helps them to attain high tractive force so that the maximum thrust can be utilized to accelerate.

At times, it may even be observed that this technique is so effective that a normal person is able to accelerate better than some modern vehicles.

The solution offered here is inspired from this technique and involves use of mechanical devices that can help simulate the same technique with vehicles.

Solution offered

Increase traction between road and vehicle by use of actuating mechanisms/ hydraulic suspensions/ hydraulic actuators/ magnetic suspension system and or any system that conforms to the principle.

The use of these devices help to exert pressure on wheels which in turn will provide high tractive force which can be used to improve the car's torque utilization, acceleration, braking and handling. Working

• Traction is generally offered by the weight of the vehicle or the air flowing over it, which may sometimes not be enough for the vehicle to perform at its maximum potential.

• An actuating mechanism/ pressure exerting system/ integrated, suspension system (as mentioned in "Solution offered") that can. exert force on the wheels, much like the suspension system already used to adjust the height of the vehicle, should be installed.

• This system can be mounted where the suspensions are mounted, replacing the suspensions.

It is placed between the vehicle's body and the wheels.

• The force exerted will act in both directions (upwards and downwards), raising the height of the vehicle^'but also exerting the force downwards, increasing the traction momentarily.

• This new suspension system should work very fast, almost instantaneously, to be able to exert pressure effectively on wheels and not just raise the height of the vehicle.

• The whole system can be controlled and the necessary actions can be executed - using a computer. based system. The actions will be based on the available tractive force, running conditions and the traction required. The parameters for traction have already been defined by the human kind by studying nature and different environments.

» This suspension system will then be able to exert pressure on wheels, providing high traction between wheels and the track's surface.

Applications

• Improved traction for acceleration from standstill.

The working explained above allows the vehicle to use torque effectively, allowing-the car to accelerate faster.

Refer the following- figure 1, figure 2, figure 3'·

· _. Improved acceleration under running condition.

The working explained above allow the vehicle to use torque effectively, under^" running conditions, allowing the vehicle to; accelerate faster even during already running conditions. Refer the following- Figure 1, figure 2, figure 3. • Improved braking.

Under braking conditions, the ear tends to skid due to lack of traction and inertia of the vehicle. This lack of traction can be overcome by using TIS.

• Improved handling.

TIS can be used to increase or decrease traction at each wheel to improve handling.

BRIEF DESCRIPTION OF THE DRAWINGS

In order that the advantages of the disclosure will be readily understood, a more particular description of the disclosure briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments of the disclosure and are not therefore to be limiting of its scope, the subject matter of the present application will be described and explained with additional specificity and detail through the use of the accompanying drawings, in which:

• Figure 1 is a representation of the vector diagrams that depict the following, also mentioned along with the figure, part (i) represents a vehicle undergoing normal acceleration/ without TIS. In this, the tractive force offered is due to the weight of the vehicle which may not be significant in many cases as discussed above. part (ii) represents a vehicle with improved acceleration/ with TIS. In this, the incoming force from suspension represents the pressure exerted by the TIS on wheels. This increases the tractive force, allowing the vehicle to use the torque effectively and thus help improve acceleration.

• _ι Figure 2 is a representation of the hypothesized improvement in the torque utilization by a * vehicle using TIS, compared to a vehicle without TIS.

• Figure 3 is a representation of the hypothesized improvement in the acceleration of the vehicle using TIS, compared to a vehicle without TIS. ,

· Figure 4 is a representation of the hypothesized improvement in the braking ability of the vehicle using TIS, compared to a vehicle without TIS. Figure 5 is a representation of the hypothesized improvement in the handling of the vehicle using TIS compared to a vehicle without TIS. In this, the handling ability is interpreted by the lateral G-force generated on turning by the vehicle without skidding.
