This International Application claims priority from a complete patent application filed in India having Patent Application No. 201941024200, filed on June 18, 2019 and titled“A SUSPENSION SYSTEM FOR TWO-WHEELER”.

FIELD OF INVENTION

Embodiments of a present disclosure relate to suspension system, and more particularly to a suspension system for two-wheeler.

BACKGROUND

Suspension is a system to reduce road shocks and vibrations in a vehicle, wherein the suspension is the system of tires, tire air, springs, shock absorber and the linkages which connects a vehicle to the wheels and enables the relative motion between the vehicle and its wheels. At present, the rear suspension system has been used on the two-wheeler to improve the performance of the two-wheeler, wherein the rear suspension system is composed of various components such as springs, linkages and shock absorbers.

However, such suspension system is incapable of providing the provision for manually adjusting the springing operation of the wheel. Also, such suspension system is incapable of providing the facility to a rider to adjust the suspension characteristics of the two-wheeler.

Hence, there is a need for an improved suspension system for two-wheeler in order to address the aforementioned issues.

BRIEF DESCRIPTION

In accordance with an embodiment of the disclosure, a suspension system for two wheeler is disclosed. The system includes a swing arm. The swing arm includes a first arm spring end operatively coupled to a rear wheel. The swing arm also includes a second swing arm end operatively coupled to a swing arm mounting point using a swing arm pivot. The system also includes a rocker arm configured to transmit force from a wheel to a spring element of a shock absorber using a rocker arm link. The system also includes a length adjustable unit. The length adjustable unit includes the rocker arm link. The rocker arm link includes a first rocker arm link end operatively coupled to the swing arm via rocker arm link mounting point. The rocker arm link also includes a second rocker arm link end operatively coupled to the rocker arm. The length adjustment unit is configured to adjust the length of the rocker arm based on a position of the rocker arm link upon moving the swing arm in up and down direction. The length adjustment unit is also configured to regulate the springing operation of the rear wheel based on the length adjustment of the rocker arm. The system also includes the shock absorber. The shock absorber includes a first shock absorber end operatively coupled to the rocker arm via slide shock mount hole. The shock absorber is configured to absorb vibrations

The system (100) may include a slider locker spring (250) (as shown in FIG. 4, FIG. 5, FIG. 7, FIG. 8 and FIG. 9) configured to keep the slider pin in a locking position. The system (100) may also include a slider lock activation and deactivation lever (260) (as shown in FIG. 4, FIG. 5, FIG. 7, FIG. 8 and FIG. 9) configured to detach the slider pin from a slider body upon pressing the lever.

The system (100) also includes a rocker arm (130) (as shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 7 and FIG. 8) placed inside the slider body (210) (as shown in FIG. 3, FIG.4, FIG.5, FIG.6, FIG.7 and FIG.8). The slider body (210) includes a first slider body end operatively coupled to the shock mounting point with the rocker arm (130). The rocker arm (130) is configured to transmit force from a wheel (180) to a spring element (140) of a shock absorber using a rocker arm link (280). In one embodiment, the rocker arm link (280) may be configured to transfer an upward vertical movement of a swing arm (160) to the rocker arm (130). The slider body (210) also includes a second slider body end operatively coupled to the swing arm (160) via the rocker arm link (280).

The swing arm (160) (as shown in FIG. 1, FIG.2 and FIG.3) includes a first arm spring end operatively coupled to a rear wheel (180). The swing arm (160) also includes a second swing arm end operatively coupled to a swing arm mounting point (290) using a swing arm pivot (300). As used herein, the term“swing arm” is a main component of rear suspension and used to hold rear wheel axle to allow the suspensions to absorb vibrations on the road. The slider body (210) also includes a rocker arm pivot axle (270) (as shown in FIG. 4, FIG. 5 and FIG. 6). The rocker arm pivot axle (270) may act as a pivot point for the slider body (210).

The system (100) also includes a length adjustable unit. The length adjustable unit includes the rocker arm link (280) (as shown in FIG. 4, FIG.5, FIG.6 and FIG.7). The rocker arm link (280) includes a first rocker arm link end operatively coupled to the swing arm (160). The rocker arm link (280) also includes a second rocker arm link end operatively coupled to the rocker arm (130).

The length adjustment unit is configured to adjust the length of the rocker arm (130) based on a position of the rocker arm link (280) upon moving the swing arm (160) in up and down direction. The length adjustment unit is also configured to regulate the springing operation of the rear wheel (180) based on the length adjustment of the rocker arm (130).

The system (100) also includes the shock absorber (140) (as shown in FIG. 1, FIG.2, FIG.3 and FIG.6). The shock absorber (140) includes a first shock absorber end operatively coupled to the rocker arm (130) via a slider shock mount hole. The shock absorber is configured to absorb vibrations. In one embodiment, the shock absorber (140) may include a coil spring configured to store and release energy subsequently for shock absorption.

In some embodiment, the rocker arm (130), the rocker arm link (280), the swing arm (160) and the swing arm mounting point (110) may act as a suspended unit.

In operation, in order to regulate the springing operation of the rear wheel (180), a rocker arm (130) contains a movable shock mounting point on one side and a rack gear, wherein a spur gear (200) rotates on the other side of the rocker arm (130) which is in contact with the rack gear upon turning on the knob (230) to enable the user to change the spring load of the shock absorber (140). Also, the rocker arm (130) is connected to swing arm (160) via rocker arm link (280), to enable a rider to adjust the suspension characteristics by twisting the knob (230). Various embodiments of the present disclosure enable a rider to adjust the suspension characteristics by twisting the knob of a rocker arm. Also, such suspension system provides a facility to regulate the springing operation of the wheel by the length adjusted rocker arm link. While specific language has been used to describe the disclosure, any limitations arising on account of the same are not intended. As would be apparent to a person skilled in the art, various working modifications may be made to the method in order to implement the inventive concept as taught herein.
