Abstract

DC60 This invention is made to simplify the maintenance of clearance for tire changes in a motorcycle consisting of a rear wheel drive unit with a rocker arm 10 mounted on one side of the rear wheel 2 in the transverse direction and with the rocker arm pivot point in front of the rear axle, and the right and left pairs of rear suspension units 7R, 7L mounted on both the right and left sides of the rear wheel 2. The mounting height of the rear suspension unit 7R on the opposite side of the drive unit is set higher than the mounting height of the rear suspension unit 7L on the drive unit side, and the mounting position of the rear suspension unit 7R on the opposite side of the drive unit in the width-of-body direction relative to the rear wheel 2 is set inward more than the mounting position of the rear suspension unit 7L on the drive unit side in the width-of-body direction relative to the rear wheel 2. This invention is made to simplify the maintenance of clearance for tire changes in a motorcycle consisting of a rear wheel drive unit with a rocker arm 10 mounted on one side of the rear wheel 2 in the transverse direction and with the rocker arm pivot point in front of the rear axle, and the right and left pairs The left side of the 7R and 7L rear suspension units is mounted on both the right and left sides of the rear wheels. The mounting height of the 7R rear suspension unit on the opposite side of the power unit should be set higher than the mounting height of the 7L rear suspension unit on the power unit side. The mounting position of the 7R rear suspension unit on the opposite side of the power unit in the width-of-body-relative-wheel-to-wheel direction should be set further inward than the mounting position of the 7L rear suspension unit on the power unit side in the width-of-body-relative-wheel-to-wheel direction.

Claims (10)

1. The motorcycle consists of: a rear wheel (2), a rocker-type rear wheel drive unit (10) mounted on one side of the wheel, and a right and left pair of rear suspension units (7R, 7L) mounted on both the right and left sides of the rear wheel (2). It is notable that the mounting height of the right rear suspension unit (7R) is higher than the mounting height of the left rear suspension unit (7L) connected to the rear wheel drive unit (10). 2. The motorcycle according to claim 1, is characterized by the rear arm (18) being mounted on the side of the rear wheel (2) opposite to the side on which the power unit (10) is mounted; and where the upper end point (7La) of the left rear suspension unit (7L) with the rear portion of the vehicle chassis (100) is mounted below the upper end point (7Ra) of the right rear suspension unit (7R) with the rear portion of the vehicle chassis (100), and the lower end point (7Lb) of the left rear suspension unit (7L) with the power unit (10) is mounted below the lower end point (7Rb) of the right rear suspension unit (7R) with the rear portion of the upper rear arm (18). 3. The motorcycle under claim 2 is characterized by the upper end point (7La) of the left rear suspension unit (7L) and the upper end point (7Ra) of the right rear suspension unit (7R) being set at equal distances to the rocker pivot point (P) of the power unit (10), and the lower end point (7Lb) of the left rear suspension unit (7L) and the lower end point (7Rb) of the right rear suspension unit (7R) being set at equal distances to the rocker pivot point (P) of the power unit (10), where the left and right suspension units (7L, 7R) are tilted differently along the vertical axis. 4. Any motorcycle under any of the claims 1 through 3 is characterized by a distance (SR) between the center axis (KR) of the right rear suspension unit (7R) and the center axis (K) of the motorcycle being shorter than the distance (SL) between the center axis (KL) of the left rear suspension unit (7L) and the center axis (K) of the motorcycle. 5. The motorcycles under any of the claims 1 through 4 are characterized by a noise reducing device (30) mounted on the side of the rear wheel (2) opposite to the side on which the power unit (10) is mounted, and is mounted under the right rear vibration damper (7R). 6. The motorcycle under claim 5, is characterized by the vehicle body cover (20) being provided for covering the sides of the vehicle body frame (100), where a silencer (30) is placed inside the vehicle body cover (20) in the width direction of the motorcycle. 7. The motorcycle under claim 6 is characterized by the catalytic converter (30s) being positioned in the muffler (30), where the muffler (30) is mounted closer to the rear wheel (2) than to the vehicle body cover (20). 8. The motorcycle in question under any of the claims 5 through 7 is characterized by a noise-reducing device (30) consisting of an elliptical cross-section in the width direction of the motorcycle and mounted beneath the right rear damping unit (7R), where the main axis (30a) of the elliptical cross-section is tilted so that the top of the main axis (30a) is directed out in the width direction of the motorcycle. 9. The motorcycles under any of the claims 1 through 8 have the following special characteristics: the power unit (10) consists of a rocker pivot point (P) at the front of the rear axle (2). 10. Any of the motorcycles under any of the claims 1 through 9 have the following special characteristics: a flat disc rear brake (40) is mounted on the side of the rear wheel opposite to the side on which the power unit (10) is mounted.
