Specification

Description:TECHNICAL FIELD
The present subject matter relates generally to a vehicle. More particularly but not exclusively, the present invention relates to a saddle type vehicle.

BACKGROUND
[0001] A vehicle generally includes a steering assembly and a suspension assembly. Steering assembly comprises handlebar assembly and a steering tube. Suspension assembly includes a lower bracket, a telescopic shocker and a wheel axle.
[0002] The Suspension assembly of the vehicle has the main function of connecting the handlebar assembly and the one or more wheel along with the frame, and also helps in steering the vehicle and also absorbing the loads when the vehicle goes over a bump or pothole. The suspension assembly includes a lower bracket assembly. The lower bracket assembly has a steering function and helps in connecting the frame to the fork assemblies.
[0001] The suspension assembly generally has the steering member and a lower bracket. In conventional vehicles, the steering member and the lower bracket are connected to each other.
[0002] The lower bracket assembly includes a lower bracket. The lower bracket has the main function of withstanding the loads arising from the one or more wheels through the forks, therefore the joinery of the lower bracket and the steering member need to have a high strength and stiffness. However, in the existing designs, both are attached together. The problem with the existing design is that when the loads acting is more, the joint might fail. The joinery between steering assembly and a suspension assembly tends to fail due to high impact force from the pothole or bumps and the reaction forces. This reduces the safety characteristics of the vehicle like it can lead to fatal accidents and injuries to the user.
[0003] Another drawback of the existing system is that in saddle type vehicle, it is observed in few saddle type vehicles where saddle type vehicle configured to have a single bracket which is configured to connect the steering tube to front fork. Thus, the lower bracket and the steering member joint is the only joint connecting the frame to the fork assembly. Hence the joint needs to be highly integral to the safety of the rider. Owing to this architecture of the vehicle which has single bracket, the impact forces and the reaction forces tends to be higher as compared to vehicles having one upper bracket and lower bracket.
[0004] It is known in the prior art to provide the reinforcement to the bracket in order to improve the strength and stiffness of the joinery. However, this leads to increased weight and cost. The increased weight affects the manoeuvrability as it is difficult to move the steering tube. Further it is known in the art to increase the thickness of the lower bracket. This leads to increase in manufacturing cost and weight. Therefore, it is challenge for the designer to reduce the overall weight of the vehicle while improving the manoeuvrability with optimum strength and stiffness of the joinery.
[0003] It is also an object of the present invention to provide a light weight and compact suspension and steering assembly for a saddle type vehicle which can withstand the higher impact loads.
[0004] It is another objective of the invention to improve the durability of the joinery of the steering assembly and suspension assembly without increasing the overall weight of the vehicle.
[0005] It is another objective of the invention to improve the manoeuvrability and handling characteristics of the vehicle.
