Classification and Anatomy of Different Types of Vehicles

Vehicles are classified based on various criteria such as the number of wheels, purpose, and origin. The broad classification includes two-wheelers, three-wheelers, four-wheelers, multi-wheelers, imported vehicles, and miscellaneous vehicles. Each category has distinct characteristics and structural anatomy.

1. Two-Wheelers

Classification:

  • Motorcycles: Includes standard bikes, cruisers, sports bikes, touring bikes, adventure bikes, and off-road bikes.
  • Scooters: Gearless or automatic transmission vehicles designed for urban commuting.
  • Mopeds: Lightweight, small-capacity motorcycles with an engine less than 100cc.

Anatomy:

  • Chassis: Backbone frame that supports all components.
  • Engine: Positioned centrally, can be two-stroke or four-stroke.
  • Transmission: Manual (clutch and gear system) or automatic (Continuously Variable Transmission - CVT).
  • Suspension: Front telescopic forks and rear dual shocks or monoshock.
  • Brakes: Drum brakes, disc brakes, or ABS (Anti-lock Braking System).
  • Fuel Tank: Located on the frame in motorcycles; under the seat in scooters.
  • Wheels & Tyres: Spoke wheels for off-road bikes, alloy wheels for standard and premium bikes.

2. Three-Wheelers

Classification:

  • Passenger Three-Wheelers: Auto-rickshaws, e-rickshaws.
  • Cargo Three-Wheelers: Used for transporting goods in urban and rural areas.
  • Special Purpose Three-Wheelers: Custom-built vehicles for disabled persons or industrial applications.

Anatomy:

  • Chassis: Ladder frame or monocoque body construction.
  • Engine: Positioned at the rear, commonly runs on petrol, diesel, CNG, or electricity.
  • Transmission: Manual or automatic (CVT in e-rickshaws).
  • Suspension: Front telescopic suspension, rear leaf springs.
  • Brakes: Drum brakes, mechanical or hydraulic system.
  • Wheels & Tyres: Small-sized reinforced tyres for load-bearing capacity.

3. Four-Wheelers

Classification:

  • Passenger Vehicles: Hatchbacks, sedans, SUVs (Sports Utility Vehicles), MUVs (Multi-Utility Vehicles).
  • Commercial Vehicles: Mini-trucks, pickup trucks, taxis.
  • Off-Road Vehicles: 4x4 vehicles, all-terrain vehicles (ATVs).

Anatomy:

  • Chassis: Monocoque construction (cars, SUVs) or ladder frame (trucks, MUVs).
  • Engine: Petrol, diesel, hybrid, or electric; varies in displacement and power output.
  • Transmission: Manual, automatic (CVT, DSG, torque converter).
  • Suspension: Independent suspension in cars, leaf springs in commercial vehicles.
  • Brakes: Disc brakes (front and rear), ABS, electronic brake-force distribution (EBD).
  • Fuel System: Fuel tank capacity varies; positioned beneath the chassis for safety.
  • Body Structure: Aerodynamic design, crumple zones for safety.

4. Multi-Wheelers (Heavy Vehicles)

Classification:

  • Transport Vehicles: Trucks, buses, trailers, lorries.
  • Construction Vehicles: Cranes, bulldozers, excavators.
  • Agricultural Vehicles: Tractors, harvesters.

Anatomy:

  • Chassis: Heavy-duty steel frame.
  • Engine: Large displacement diesel engines (turbocharged for efficiency).
  • Transmission: Manual (synchromesh gears) or automatic.
  • Suspension: Air suspension or leaf spring suspension.
  • Brakes: Air brakes, hydraulic braking system, retarder brakes for heavy loads.
  • Axles: Dual rear axles for load distribution.
  • Body Structure: High ground clearance, reinforced steel body.

5. Imported Vehicles

Classification:

  • Luxury Cars: Lamborghini, Ferrari, Rolls-Royce, Bentley.
  • Exotic Motorcycles: Ducati, Harley-Davidson, MV Agusta.
  • Custom Vehicles: Limousines, armored vehicles.

Anatomy:

  • Chassis: Advanced materials like carbon fiber, aluminum alloy.
  • Engine: High-performance turbocharged or hybrid engines.
  • Transmission: Dual-clutch automatic, paddle-shift technology.
  • Suspension: Adaptive air suspension, magnetic ride control.
  • Brakes: Carbon ceramic disc brakes for high performance.
  • Electronics: Advanced driver assistance systems (ADAS), connected vehicle technology.
  • Aerodynamics: Active aerodynamics for high-speed stability.

6. Miscellaneous Vehicles

Classification:

  • Electric Vehicles (EVs): Battery-powered two-wheelers, four-wheelers, buses.
  • Hybrid Vehicles: Combination of IC engine and electric motor.
  • Special-Purpose Vehicles: Ambulances, fire trucks, garbage trucks.
  • Military Vehicles: Armored personnel carriers, tanks.

Anatomy:

  • Chassis: Varies as per purpose; reinforced for strength.
  • Powertrain: Electric motors, hybrid engines, or diesel engines.
  • Braking System: Regenerative braking in EVs, heavy-duty brakes in military vehicles.
  • Safety Features: Bulletproofing (military), reinforced structures (ambulance).
  • Control Systems: Advanced navigation, self-driving features in autonomous vehicles.

Conclusion

The classification of vehicles depends on their structure, purpose, and technology. Two-wheelers and three-wheelers cater to urban commuting, four-wheelers serve both private and commercial needs, while multi-wheelers and specialized vehicles serve industrial, agricultural, and military purposes. With advancements in technology, electric and autonomous vehicles are becoming the future of transportation.

Contract Notes - 3

Object and Consideration in Contract Act, 1872 Object of a Contract The object of a contract is the purpose or intention behind the agreement between parties. For an agreement to be enforceable as a contract, its object must be lawful and not opposed to public policy or morality. The lawful object is a necessary element of a valid contract. If the object of the contract is illegal or immoral, the agreement is void. Section 23 of the Indian Contract Act states that the consideration or object of an agreement is lawful unless it is forbidden by law, or is opposed to public policy, or is fraudulent, or involves injury to the person or property of another, or the court regards it as immoral or opposed to public policy. Significance The object ensures that contracts are not made for purposes harmful to society or contrary to law. This protects public interest and maintains ethical standards in contractual relations.
