BACKGROUND

[0002] With the augmentation of technology in the automotive industry, there has been an enormous development of technology in multiple verticals of the product line-ups and technology front for any vehicle. Due to the very high penetration rate of two-wheelers in the current urban and rural ordinary people in India, the safety and reliability of two-wheeler vehicles when they are stopped or parked are being increasingly valued. More specifically, parking brake mechanism of a vehicle such as a motorcycle, a scooter, a three-wheeled vehicle or a four-wheeled vehicle such as an All-Terrain Vehicle (ATV), wherein the parking brake setting when the two-wheeler is stopped provides a guarantee for the safety and reliability of the stop. Although, there exists a number of solutions to the problem and requirement of such parking brake mechanisms; however, there appears to be inherent and other problems/shortcomings associated with each.

[0003] One of the outgoing mechanism for applying the brake, while in a parking condition of the vehicle, is achieved by mechanically fixing/locking a brake lever in a fixed position such that the braking condition is achieved and maintained even if the rider/user leaves the brake lever after application. However, there may exist a plurality of shortcomings associated with such parking brake mechanism and a few of such shortcomings may be a reduced life and effectiveness of the brake lever as the brake lever is repeatedly locked and unlocked, unwanted stress to the entire length of the brake-force transmission cable/wire, and additional manual operational requirement of an added mechanical part/stopper at the brake lever, which is undesirable. [0004] In another approach of parking brake arrangement for a scooter vehicle, as disclosed in the Indian Patent Application No. 1013/CHE/2012, comprises a side stand, a brake cam lever, an auxiliary brake cable, at least two abutments. The aforementioned components are configured and arranged such that the brake is applied to the wheel of the vehicle in an event the side stand is applied to rest the vehicle. To achieve the same, the side stand is connected to the brake cam lever of the wheel, through the auxiliary cable. However, such arrangement may lead to a plurality of associated drawbacks, such as introducing additional brake cable thereby increase in cost due to maintenance and space occupancy of channels for the brake cable.

[00052] The braking system (190) comprises a second stopper member (233) (shown in Figure 3) is fixedly coupled to the second outer sheath (143) of the first brake-force transmission member (140) to restrict the front ward movement of the second outer sheath (143). The second stopper member (233) abuts the first plate member (210) to restrict the movement of the second outer sheath (143) of the first brake -force transmission member (140).

[00053] The pushing member (246) is configured to abut and push the abutting end (235) of the second outer sheath (143) of the first brake-force transmission member (140), as the side stand (140) is moved from the disengaged position (A) to the engaged position (B). The side stand (240) is rotated towards the engaged position (B), when the vehicle (100) needs to be parked. As the pushing member (246) pushes the abutting end (235) of the second outer sheath (143), the second outer sheath (143) experiences compression (the first brake -force transmission member (140) moves downward as a result of the compression of the second outer sheath (143)), thereby inducing a reaction pull on the inner brake wire (142) connected to the rear brake arm (149). The reaction-pull induced on the inner brake wire (142) causes the rear brake device (145) to engage, thereby braking the vehicle (100) in parked condition.

[00054] As shown in Figure 2, 3, and 4, the disengaged position (A) of the side stand (240) and the braking system (190) is shown. The side stand (240) rotates/pivots from the disengaged position (A) towards the engaged position (B). Figures 3, 4, 5 depicts the events, in sequence, of applying a parking brake upon engagement of the side stand (240). As shown in Figure 4, the pushing member (246) abuts the abutting end (235) of the second outer sheath (143) of the first brake-force transmission member (140) (shown in Figure 4). As shown in Figure 5, the pushing member (246) pushes the first brake -force transmission member (140) towards rear portion of the vehicle (100) (shown in Figure 5), thereby inducing a reactive pull on the inner brake wire (142) connected to the rear brake arm (149). The reactive pull induced generates a brake force on the rear brake device (145) to engage, thereby braking the vehicle (100) in parked condition. Further, the spring member (230) is configured such that the second outer sheath (143) retains the original position, once the side stand (240) is disengaged i.e. moved to the disengaged position (A).

The plunger (402) is fixedly coupled to the inner brake wire (414). The movement of inner brake wire (414) induces a movement of the plunger (402). The second outer sheath (412) comprises an abutting end (415). In the illustrated example, the abutting end (415) abuts the plunger (402). Alternatively, the abutting end (415) of the second outer sheath may be disposed at a distance from the plunger (402), without limiting the scope of the invention. The first outer sheath (410) abuts the flange portion (404). [00057] The vehicle (100) comprises a flanged member (322). The flanged member (322) is disposed on the mounting bracket (126). In the illustrated example, the flanged member (322) is formed integral with the mounting bracket (126). In another embodiment, the flanged member (322) is formed independently and is coupled to the mounting bracket (126), without limitations. The flanged member (322) comprises a hole (not shown).

[00058] The braking system (190) comprises a pull member (350), a spring member (330), a first abutment member (352), a second abutment member (355), and a first connector (356). In the illustrated example, the pull member (350) is a rod member extending through the hole on the flange member (322). Alternatively, the pull member (350) may be a wire, without any limitations. The pull member (350) comprises a first pulling member end (351) and a second pulling member end (353) opposite to the first pulling member end (351). The first abutment member (352) is fixedly coupled to the pull member (350). The first abutment member (352) is disposed closer to the first pulling member end (351). The first abutment member (352) comes into contact with the pushing member (320), when the side stand (140) is moved from a disengaged position (C) (shown in Figure 6) to an engaged position (D) (shown in Figure 8). The second abutment member (355) is disposed on the first pulling member end (351). The second abutment member (355) restricts the pull member (350) from escaping out of the hole on the flanged member (322). The second abutment member (355) abuts the flanged member (322) to restrict the escape of the pull member (350).

[00059] The spring member (330) is disposed between the first abutment member (352) and the flanged member (322). The spring member (330) provides necessary biasing force to the pull member (350) during operation. The second pulling member end (353) of the pull member (350) extends towards the front of the vehicle (100). The second pulling member end (353) is coupled to the second outer sheath (412) of the first brake-force transmission member (140) via the first connector (356). More particularly, the second pulling member end (353) is connected to the abutting end (415) of the second outer sheath (412) via the first connector (356).

[00060] The pull member (350) is configured to pull the second outer sheath (412), as the pull member (350) is pushed by the pushing member (320), when the side stand (140) is moved from the disengaged position (C) to the engaged position (D). [00061] As shown in Figure 6, the disengaged position (C) of the side stand (240) and the braking system (190) is shown. When the side stand (240) is rotated about the mounting bracket (126) to the engaged position (D) to park the vehicle (100). The pushing member (320) pushes the first abutment member (352), thereby pushing the pull member (350) towards rear end of the vehicle (100). As the pull member (350) moves within the hole of the flanged member (322) under the biasing force of the spring member (330), it pulls the abutting end (415) of the second outer sheath (412) via the first connector (356) towards rear of the vehicle (100). As the pull member (350) pulls the abutting end (415) of the second outer sheath (412), the second outer sheath (412) experiences compression (the first brake -force transmission member (140) moves downward as a result of the compression of the second outer sheath (412)), thereby inducing a reaction pull on the inner brake wire (414) connected to the rear brake arm (149). The pull induced generates a brake -force on the rear brake device (145) to engage, thereby braking the vehicle (100) in parked condition. Further, the spring member (330) is configured such that the second outer sheath (412) retains the original position, once the side stand (240) is disengaged i.e. moved to the disengaged position (C).

[00062] Various embodiments of the present invention advantageously provide the braking system (190) that leverages from having an additional brake cable which may increase the overall cost due to maintenance and space occupancy of channels for the brake cable. Further, the present invention advantageously provides the braking system (190) that does not require additional member to lock the brake lever while parking and thereby increasing the life and effectiveness of the brake lever by leveraging the brake lever from unwanted stress to the entire length of the first brake-force transmission member (140). Further, the braking system (190) provides a cost effective solution without hindering the normal operation of the first brake-force transmission member (140) i.e. applying the rear brake device (145) by the first brake lever (160).

[00063] While few embodiments of the present invention have been described above, it is to be understood that the invention is not limited to the above embodiments and modifications may be appropriately made thereto within the spirit and scope of the invention.

[00064] While considerable emphasis has been placed herein on the particular features of this invention, it will be appreciated that various modifications can be made, and that many changes can be made in the preferred embodiments without departing from the principles of the invention. These and other modifications in the nature of the invention or the preferred embodiments will be apparent to those skilled in the art from the disclosure herein, whereby it is to be distinctly understood that the foregoing descriptive matter is to be interpreted merely as illustrative of the invention and not as a limitation.
