1. Field of the Invention
The present invention relates to a constant speed device, and more particularly to a constant speed device for providing a constant speed effect to a motorcycle.
2. Description of the Prior Arts
When riding a motorcycle, one of the rider's hands needs to grip and rotate a twist grip throttle of the motorcycle to move the motorcycle forward. When the hand removes from the twist grip throttle of the motorcycle, the moving speed of the motorcycle is decelerated. Therefore, the moving speed of the motorcycle is related to and controlled by the rotating angle of the twist grip throttle of the motorcycle. In a long-distance, the rider needs to grip and rotate the twist grip throttle of the motorcycle continually to keep the motorcycle moving forward. The long period of time of griping and rotating the twist grip throttle of the motorcycle will cause the rider feeling tired and may get hurt or die in a traffic accident. In addition, when the rider wants to keep the motorcycle moving at a constant speed in a long-distance, the rider needs to control the rotating angle of the twist grip throttle of the motorcycle by hands and this will cause the motorcycle to move at an indefinite speed. Therefore, the conventional motorcycle does not have a constant speed function.
In order to provide a constant speed effect to the motorcycle to allow the rider not to grip and rotate the twist grip throttle to control the moving speed of the motorcycle by hands, an electronic constant speed device can be mounted on the motorcycle. However, the cost of assembling the conventional electronic constant speed on the motorcycle is expensive and inconvenient.
To overcome the shortcomings, the present invention provides a constant speed device for motorcycle to mitigate or obviate the aforementioned problems.
The main objective of the present invention is to provide a constant speed device and more particularly to a constant speed device that can provide a constant speed effect to a motorcycle.
The constant speed device for a motorcycle having a twist grip throttle in accordance with the present invention has a clamping segment and a pressing segment. The clamping segment a clamping space, an abutting face and a gap. The clamping space is defined through the clamping segment to mount around the twist grip throttle of the motorcycle. The abutting face is formed around the clamping space of the clamping segment to abut with the twist grip throttle. The gap is formed through a side of the clamping segment and communicates with the clamping space to allow the twist grip throttle mounting in the clamping space of the clamping segment. The pressing segment is connected to the clamping segment opposite to the gap.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
With reference to
The clamping segment (10) has a free side, a clamping space (11), an abutting face (12) and a gap (13). The clamping space (11) is defined through the clamping segment (10) to mount around the twist grip throttle (30) of the motorcycle. The abutting face (12) is formed around the clamping space (11) of the clamping segment (10) to abut with an external surface of the twist grip throttle (30). The gap (13) is formed through the free side of the clamping segment (10) and communicates with the clamping space (11) to make the clamping segment (10) expandable for holding the twist grip throttle (30) in the clamping space (11). Preferably, the clamping segment (10) has a first clamping arm (14) and a second clamping arm (15). The clamping space (11) is defined between the gap (13), the clamping arms (14, 15) of the clamping segment (10). Each clamping arm (14, 15) has two abutting faces (12) formed in an inner side of the clamping arm (14, 15) at an angle relative to each other. Preferably, each abutting face (12) of the clamping arms (14, 15) has a non-slip segment.
The pressing segment (20) is connected to the connecting side of the clamping segment (10) opposite to the gap (13), may be formed with the clamping segment (10) to form a one-piece constant speed device and has a first stab (21), a second stab (22) and an expansion joint (23). The first stab (21) is formed with the first clamping arm (14). The second stab (22) is formed with the first stab (21) opposite to the first clamping arm (14) and is formed with the second clamping arm (15). The expansion joint (23) is formed between the stabs (21, 22) and communicates with the clamping space (11) of the clamping segment (10).
With reference to
The constant speed device for a motorcycle in accordance with the present invention has a simple structure and can provide a constant speed effect to the motorcycle so that the oil consumption of the motorcycle can be efficiently reduced. The constant speed device in accordance with the present invention can be easily assembled onto the twist grip throttle (30) to fix the moving speed of the motorcycle at a constant speed. In addition, if the constant speed device is not in use, the constant speed device can be stored easily. The constant speed device in accordance with the present invention is an extrinsic-supplementary element to the motorcycle and can be mounted on the twist grip throttle (30) conveniently and practicably in use and has a low-cost relative to the conventional electronic constant speed device and this can satisfy the requirements of the users and the market.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
