Riding type two-wheel motorcycle

Abstract

The invention discloses a bestriding type of dual-wheel motorcycle. The frame of the motorcycle consists of two parallel upper longitudinal beams and two parallel lower transverse bent beams, which are connected to the main tube of the motorcycle head. The rear end of the frame is ream jointed to one flat triangle fork through the flat folk spindle. The upper longitudinal beams have a rear section which gradually declined downward for the purpose of reducing the height of the motorcycle seat. The upper inclined forked tube of the flat triangle fork extends itself along the extending line of the rear section of the upper longitudinal beam. The rear shock absorber, which is horizontally mounted, is parallel with the rear section of the upper longitudinal beam and is located below the seat. The front end and the rear end of the rear shock absorber are beam jointed with the upper longitudinal beam and the flat triangle fork respectively. An air filter is available near the point where the upper longitudinal beam, the lower bent beam connected with the main tube of the motorcycle head. Below this point and on the lower bent beam, a water cooler is equipped. A water-cooling motor is mounted on the suspending device equipped on the frame. The front pedals are mounted on the front turning points, which are near the lower end of the lower bent beam. The two pedals extrude out of the frame on both the right side and left side. These pedals can reduce the height of the seat and improve the shock-absorbing effect and comfort in driving.

Description

technical field [0001] The invention relates to a two-wheeled motorcycle, in particular to a straddle-type two-wheeled motorcycle commonly known as a Prince Chariot. Background technique [0002] The frame of the current straddle type two-wheeled motorcycle commonly known as the Prince's Car is generally welded on the front main pipe with an upper curved beam and a lower inclined beam. The bottom frame connected at the lower end is connected, the rear frame supporting the vehicle seat is welded with the upper curved beam, the engine is located on the bottom frame, and an air filter is arranged above the oblique rear of the engine. Because the position of the air filter is located under the seat and occupies the position of the seat, the setting of the seat position of the prince car for the purpose of reducing the height of the seat to improve riding comfort is not ideal. Especially for the medium-sized prince car made for people of medium height, because its frame adopts a...

AI Technical Summary

Problems solved by technology

Since the air filter is located under the seat and occupies the seat position, the setting of the seat position of the prince car for the purpose of reducing the height of the seat to improve riding comfort is not ideal

Especially for the medium-sized prince car made for people of medium height, because its frame adopts an upper curved beam and a lower inclined beam located on the longitudinal axis of the vehicle body, the effective space for installing parts on the frame is limited, resulting in The air filter has not yet found a suitable installation position, and the purpose of further lowering the seat cannot be realized

Due to the high position of the seat, the position of the driver's footrest is relatively rearward, so that the angle between the driver's knees is relatively small when riding, which affects the comfort of riding

Moreover, due to the limited effective space for mounting parts on the frame, the battery of the motorcycle is usually arranged on the left or right side under the seat, which increases the width of the vehicle body, thereby increasing the width of the straddle and affecting the riding comfort.

And, because the rear shock absorber of medium-sized prince car is usually installed vertically between the rear frame and the front part of the flat fork, the design of its shock absorbing stroke is limited, so it is impossible to further improve the shock absorbing performance of the motorcycle, which affects the ride quality. riding comfort

At present, the front shock absorber of a medium-sized prince car usually adopts the shock absorber fork tube to be fixedly connected to the steering device at the top, and the shock absorber bottom tube is located at the bottom to assemble the front wheel. The shock effect has a certain influence
