, Description:TECHNICAL FIELD
[001] The embodiments herein generally relate to braking systems in vehicle and more particularly, to an emergency braking system in vehicles.
BACKGROUND
[002] Braking system is one of the major safety systems in vehicle which aids in stopping or slowing down the vehicle during the time of collision. There are many types of braking systems available in present day vehicles. If the main braking system fails, then there is no auxiliary or emergency braking system in vehicle due to which the vehicle may not get stopped or slowed down at the intended time which ends up in an unavoidable collision. Hence, there is a need in the art for a secondary emergency braking system in vehicle which can be used to stop the vehicle during the failure of main braking system in vehicle.

[007] The embodiments herein are illustrated in the accompanying drawings, throughout which like reference letters indicate corresponding parts in the various figures. The embodiments herein will be better understood from the following description with reference to the drawings, in which:
[008] FIG. 1 depicts a sectional view of the emergency braking system, according to an embodiment as disclosed herein.

DETAILED DESCRIPTION
[009] The embodiments herein and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments that are illustrated in the accompanying drawings and detailed in the following description. Descriptions of well-known components and processing techniques are omitted so as to not unnecessarily obscure the embodiments herein. The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein.
[0010] The embodiments herein achieve an emergency braking system in a vehicle. Further, the embodiments herein achieve the emergency braking system which can be retrofitted with the existing transmission system available in the vehicle. Furthermore, the embodiments herein achieve the emergency braking system which is simple in construction. Referring now to the drawings, and more particularly to Fig. 1, where similar reference characters denote corresponding features consistently throughout the figures, there are shown embodiments.
[0011] FIG. 1 depicts a sectional view of an emergency braking system (100), according to an embodiment as disclosed herein. For the purpose of this description and ease of understanding, the emergency braking system (100) is explained herein below with reference to be components typically available in the vehicle. In an embodiment, the emergency braking system (100) includes an actuating lever (102), a spring (104) and a braking pad (106), where the braking pad (106) is connected to one end of the actuating lever (102). The actuating lever (102) is made of an “L-shaped” structure in which one end (102a) is connected to the spring (104) and the other end (102b) is connected to the brake pad (106). One end of the spring (104) is connected to the actuating lever (102). The other end of the spring (104) is connected to a vehicle body structure (108). In an embodiment, the spring (104) is provided with a lock (not shown) and the spring (104) is assembled at a compressed state between the actuating lever (102) and the vehicle body structure (108). The final drive (110) of the vehicle is provided with a conical surface pad (112) for engagement with the braking pad (106). The braking pad (106) is adapted to engage with the friction pad (112) of the final drive (110) to facilitate braking of the vehicle in a gradual manner on movement of the actuating lever (102).
[0012] The spring (104) is assembled at a compressed state between the actuating lever (102) and the vehicle body structure (108). The vehicle body structure defines the interior surface of vehicle or frame of the vehicle. In one of the embodiments the spring (104) is attached to near to the seating area of vehicle frame.
[0013] The working of the emergency braking system (100) is explained in reference to Figure 1. When the user actuate the emergency braking system (100) through the actuating lever (102), the mechanical lock (not shown) which keeps the spring (104) in compressed state gets released and moves the actuating lever (102) in a direction towards the final drive (110) of the vehicle transmission system. As the other end of the actuating lever (102) is provided with the braking pad (106), it starts to engage with the conical friction pad (112) provided at the final drive (110) of the vehicle transmission system. The final drive (110) is the component which is always in rotation and transfers the power to the wheels of the vehicle. As the braking pad (106) engages slowly with the conical friction pad (112), the rotation of the final drive (110) also slows down. When the complete engagement of the braking pad (106) with the conical friction pad (112) of the final dive (110), happens, the rotation of the final drive (110) stops, and the vehicle comes to a complete stop as the power transfer to the wheels is stopped. The spring (104) is configured to release in a smooth manner so as to prevent abrupt stoppage of the vehicle.
[0014] For the purpose of this description and ease of understanding, the vehicle is considered to be any of automobile, truck, car, 3 wheeler vehicles and 4 wheeler vehicles or any other vehicle.
[0015] In another embodiment, the actuation lever (102) is pushed against the final drive (108) of the vehicle for emergency braking with the spring mounted between the actuating lever (102) and the vehicle body structure in the uncompressed state.
[0016] The technical advantages of the emergency braking system (100) are as follows. The emergency braking system in the vehicle which is not dependent on the main braking system. Further, the emergency braking system can be retrofitted with the existing transmission system and is simple in construction, yet facilitates in emergency braking. Moreover, the emergency braking system is easy to manufacture and is inexpensive.
[0017] The foregoing description of the specific embodiments will so fully reveal the general nature of the embodiments herein that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. Therefore, while the embodiments herein have been described in terms of embodiments, those skilled in the art will recognize that the embodiments herein can be practiced with modification within the spirit and scope of the embodiments as described herein.
