Description

[Detailed Description of the Invention] This invention relates to a motorcycle engine protector.

Among motorcycles, there is a type of vehicle called an off-road vehicle that mainly runs on rough terrain. In this type of motorcycle, the engine may hit a protruding rock, tree stump, etc., and the engine case may crack and become unusable. In order to protect the engine case from this, the lower side of the engine case is covered with a protector plate formed from a steel plate or the like. However, by doing this, rocks etc. protruding from the road surface can be avoided from hitting the protector plate and hitting the engine case, preventing damage to the engine case, but if the impact is severe. This shock may cause the vehicle to lose its balance and fall, causing damage to other parts, and the driver may also fall over and be injured.

This idea is an improvement based on these points.
Embodiments of the present invention shown in the drawings will be described below.

A protector 4 in which a plurality of rollers 2 are rotatably held by a support shaft 3 is provided between left and right frame bodies 1 extending back and forth. And this protector 4,
It is placed below the engine 5 and fastened to the bottom of the frame 6 with bolts 7.

However, when driving a motorcycle,
If rocks or the like protrude from the road surface, they will hit the protector 4 before hitting the engine 5, thereby preventing damage to the case from hitting the engine 5. Since the protector 4 has a plurality of rollers 2 arranged in a rotatable manner, the rollers 2 rotate when they hit a protrusion such as a rock, and can ride over the protrusion one after another, thereby absorbing the impact of collision with the protrusion. It can be alleviated. In this way, it is possible to get over the protrusion, or even if it is not possible to get over the protrusion, the impact can be alleviated, the loss of balance due to the impact can be reduced, and falling can be prevented.

As explained above, this invention provides a protector in which a plurality of rollers are rotatably attached to a support shaft between the left and right frames, and the protector is fastened to the lower part of the frame on the lower side of the engine. Therefore, the protector can prevent protrusions on the road surface from hitting the engine case, thereby preventing the protrusions from hitting the engine case and damaging it. Since the protector has rotatable rollers lined up, the rollers that hit the protrusion rotate one after another, allowing the protector to overcome the protrusion. Furthermore, even if the vehicle cannot be overcome, it is possible to reduce the impact and prevent the vehicle from losing its balance, thereby preventing the vehicle from falling.
