Description

  The present invention provides a pair of left and right brackets each having a power source support portion that is detachably connected to a power source and a vehicle body frame attachment portion that is detachably attached to a vehicle body frame. The present invention relates to a saddle-ride type vehicle provided with a swing arm support portion that supports a front end portion of a swing arm that swings up and down.

  Such a saddle-ride type vehicle is known from Patent Document 1.

Japanese Patent No. 4695023

  The bracket as disclosed in Patent Document 1 tends to be large, and there is a problem that it is difficult to ensure rigidity.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a saddle-ride type vehicle capable of improving the rigidity of the bracket.

In order to achieve the above object, the present invention provides a pair of left and right brackets each having a power source support portion that is detachably connected to a power source and a body frame attachment portion that is detachably attached to the body frame. In a saddle-ride type vehicle provided with a swing arm support portion that swingably supports a front end portion of a swing arm that pivotally supports a wheel at a rear end portion, the power source support portion and the vehicle body frame attachment portion include: A pair of cross members, which are respectively arranged above and below the swing arm support portion and have the same shape, are separated from the power source support portion, the body frame mounting portion, and the swing arm support portion of the pair of left and right brackets. If the connection between the set cross member connection parts, or the connection of the cross member connection part of the pair of left and right bracket The so as to perform connection to the vehicle body frame cross members connecting portions, the two places which is divided and the top and bottom of the swing arm support portion in the front-rear direction intermediate portion of the power source support and the vehicle body frame mounting portion It is a first feature that it is provided between the arranged cross member connecting portions.

According to the present invention, in addition to the configuration of the first feature, the power source support portion is disposed either before or after the swing arm support portion, and the vehicle body frame mounting portion is either before or after the swing arm support portion. The second feature is that it is arranged on the other side .

The present invention is found that, in addition to the configuration of the first or second feature, a pivot shaft provided between the swing arm support portions of the pair of left and right brackets, left and right sides of the front end portion of the swing arm Bearing means are respectively provided between them and inserted into the front end portion of the swing arm while being restricted from moving in the direction along the axis of the pivot shaft to form a part of the bearing means and the axis of the pivot shaft A bearing component capable of rotating relative to the swing arm around is protruded laterally from a front end portion of the swing arm and abutted against the inner surfaces of the pair of left and right swing arm supports; Three features.

According to a first aspect of the present invention, the power source support portion, or the vehicle body frame mounting portion and the swing arm support portions are connected by calyx Rosumenba between cross member connecting portion which is set separately from a pair of left and right brackets, since torque Rosumenba be connected between the cross member connecting portions of the two brackets are connected to the body frame, the rigidity of both the brackets, it is possible to prevent a reduction in vehicle body rigidity due to the deformation of the bracket.

Also, it is possible to increase the rigidity of the bracket by connecting between the left and right brackets in a pair of cross members, yet to facilitate manufacture by a pair of cross members and the same shape, to suppress an increase in cost be able to.

Furthermore , since the power source support portion and the vehicle body frame attachment portion are respectively above and below the swing arm support portion, the swing arm support portion can be firmly supported.

According to the second feature of the present invention, since the power source support portion and the vehicle body frame mounting portion are arranged separately at the front and rear of the swing arm support portion, the vibration transmitted from the internal combustion engine to the bracket and the swing arm are used. The bracket is easily deformed with respect to the load from the ground input to the bracket, but the deformation can be effectively prevented by the cross member.

Further, according to the third feature of the present invention, a part of the bearing means provided between the pivot shaft provided between the pair of left and right swing arm support portions and the left and right sides of the front end portion of the swing arm is configured. A pair of left and right swing arm support portions projecting from the front end portion of the swing arm to the side while the bearing constituent member capable of relative rotation with the swing arm is restricted from moving in the direction along the axis of the pivot shaft. Therefore, the spacer is not disposed between the swing arm and both swing arm support portions, and the coupling rigidity of both brackets becomes higher.
