Description

Motorcycle with shock-absorbing function

An embodiment of the present invention relates to a motorcycle, and more particularly to a motorcycle with a shock-absorbing function.

Motorcycles are generally equipped with shock absorbers to absorb vibrations and improve the riding comfort. In conventional technology, shock absorbers are generally installed between the rear swing arm and the frame. Specifically, there are two shock absorbers on the left and right sides, one of which is installed between the left rear swing arm and the frame, and the other is installed between the right rear swing arm and the frame. Conventional shock absorbers are used in large quantities and are large in size, which not only increases the cost of parts, but also limits the freedom of space configuration of the motorcycle.

The embodiment of the present invention is to provide a motorcycle with a shock-absorbing function in order to solve the problem of the prior art, including a power unit, a swing arm unit, a frame, a shock absorber and a connecting rod unit. The power unit includes an output shaft. The swing arm unit is pivoted to the power unit, wherein the swing arm unit is suitable for pivoting around an axis, and the output shaft is located on the axis. The swing arm unit includes a first swing arm and a second swing arm, and the first swing arm is connected to the second swing arm. The power unit is connected to the frame. The shock absorber passes between the first swing arm and the second swing arm, wherein one end of the shock absorber is connected to the frame. The other end of the shock absorber is connected to the connecting rod unit.

In one embodiment, the connecting rod unit connects the power unit and the swing arm unit.

In a vertical direction, the first bolt is located above the first rocker arm, and the second bolt is located below the first rocker arm.

In one embodiment, the connecting rod unit includes a connecting rod, a first connecting rod plate and a second connecting rod plate, one end of the connecting rod is pivoted to the power unit, the shock absorber is pivoted to the other end of the connecting rod, the first connecting rod plate and the second connecting rod plate are pivoted to the connecting rod, and the first connecting rod plate and the second connecting rod plate are also pivoted to the connecting bracket.

In one embodiment, the connecting rod is substantially L-shaped, and includes a bent portion, and the first connecting rod piece and the second connecting rod piece are hinged to the bent portion.

In one embodiment, the connecting bracket includes a first hinge portion and a second hinge portion, the first hinge portion is formed at the bottom of the first bracket section, the second hinge portion is formed at the bottom of the second bracket section, the first connecting rod piece is hinged to the first hinge portion, and the second connecting rod piece is hinged to the second hinge portion.

In one embodiment, the motorcycle further includes a rear wheel, wherein the rear wheel is pivotally connected to the first swing arm and the second swing arm, the frame includes a frame pivot portion, the shock absorber is pivotally connected to the frame pivot portion, and in a horizontal direction, the frame pivot portion is located between the rear wheel and the axis.

In one embodiment, the motorcycle further includes a first gear, a second gear, and a transmission member, wherein the first gear is connected to the output shaft, the second gear is connected to the rear wheel, and the transmission member is connected to the first gear and the second gear.

In the embodiment of the present invention, a mid-mounted shock absorber is used and matched with a connecting rod unit. The shock absorber of the embodiment of the present invention is located between the axis and the connecting bracket. The motorcycle structure using the embodiment of the present invention can lower the position of the shock absorber so that the space above the shock absorber can be more fully utilized. The shock absorption performance of the suspension system can also be greatly improved. In one embodiment, the suspension system of the motorcycle of the embodiment of the present invention can withstand greater impact (the rear section of the compression stroke curve can withstand a greater load, and the front section of the compression stroke curve is not too hard and can absorb road vibration).

In one embodiment, the motorcycle of the present invention includes components such as a steering wheel, a front wheel, a rear wheel, a seat, and a power system.
