FIELD OF INVENTION The present invention relates to the field of automobile towing vehicles. More specifically the present invention is directed towards motorbike assisted towing trolley for four-wheeler.
BACKGROUND OF THE INVENTION 5
Increasing population leads to the high usage of vehicles. Large number of vehicles/four wheelers are increasing per year on the roads. Due to increasing vehicle density, basic problems related to vehicles are also becoming a headache. As machines are susceptible to failure and can halt anytime, anywhere without any previous indication, for the last several years, towing of cars/vehicles was just a matter of holding the car strongly. But with the passage of time, we had 10 huge advancement in cars and its technology and hence parallel advancement in towing technology is also in demand.
Now a day various new designs of cars have been launched with modified bumpers at both the ends. These modifications create issues when car is needed to be towed in various circumstances. Tow connections with bumpers are eliminated because of these changes. Traditional towing 15 mechanism of holding car from the rear bumper causes damage.
Several mechanical methods are known for the towing purpose of four wheelers. Previously mentioned towing methods are cumbersome and do not provide flexibility in the mechanism of towing the vehicle. E.g. flatbeds are used which are long and difficult to manage in cases of narrow streets or car stuck between two vehicles. Traditional methods comprise use of large 20 manual jacks with heavy vehicle assistance. Moreover it requires lot of manpower to pull out and attach towing hook to the bumpers. High cost is also matter of concern for using previously used towing mechanism.
Towing process basically requires a proper empty space to tow the car/vehicle but due to increasing vehicle density rate it is almost impossible to get sufficient space all the time. Either 25 traffic is blocked or damage is done thereby creating lots of inconvenience to the passers-by. There is always a need to get a compact system for car towing which can easily move the car even from the crowded area.

The present invention provides solution to all the above mentioned problems by suggesting a motorbike assisted towing trolley for four wheelers.
The present invention provides an easy mechanism for towing which does not require bumper lifting or large supporting vehicles. It provides a simple and compact towing system comprising pistons, wheel axis, electromagnetic jacks, electromagnetic frames, towing frames and 5 removable blocks. This towing mechanism is further attached to a motorbike with the help of towing frame. The tow trolley is moved below the car and then piston automatically works as a jack without use of any external effort. Electromagnetic frames gets activated via the power of battery provided with the motorbike. These frames hold the car tightly while towing it from one place to another. 10
Minimizing the manual effort and providing a compact system/mechanism of towing, the present invention brings an easy and cost-effective solution to the several towing related pitfalls.
Problems in existing towing mechanisms
The existing mechanisms are difficult to use as they are very heavy systems and also it requires more man force or crane mechanism for towing the vehicle. 15
The crane mechanism if used requires a hook that has to be placed in the four wheeler bumper that can damage the bumper of four-wheeler.
The towing mechanisms are difficult to carry and are very costly.
