Abstract

A structure for installing a rear cushion in a motorcycle having a hydraulic shock absorber with a subsidiary cylinder used as the suspension device. The swing arm includes a pair of left and right arm portions, the respective front portions being coupled with a first cross member and a second cross member. A pair of cushion brackets extend in the back-and-forth direction with the upper portion of the rear cushion sandwiched therebetween. The front and rear ends of the cushion brackets are coupled to the first and second cross members, thereby supporting the cushion brackets at both ends. An upper portion of the rear cushion fits within a space enclosed by the first and the second cross members, and the left and right cushion brackets, and is coupled to the intermediate portion of the left and right cushion brackets.

Description

technical field [0001] The present invention relates to a structure for mounting a rear shock absorber in a motorcycle, and to a hydraulic shock absorber with an auxiliary cylinder for use in a motorcycle suspension. Background technique [0002] In some rear suspension mechanisms of motorcycles or similar vehicles, the front end of the rear swing arm on the side of the vehicle body is supported by a swing shaft in such a manner that it can swing freely, and the rear swing arm is provided on the upper part of the front end side. There is a buffer bracket, the lower end on the front end side of the rear swing arm is connected to the side of the vehicle body through a link, and the upper and lower parts of the rear buffer are supported between the link and the buffer between stents (for example, refer to Japanese Patent Publication (Laid-open) No. 2002-68066). [0003] In this conventional structure, a pair of left and right rear swing arms are provided with the above-describ...
