Abstract

PURPOSE:To increase the capacity of an equipment accommodation space part by curving a rear suspension supporting bracket in coincidence with the rear part shape of a helmet accommodation chamber and positioning a rear suspension supporting part in a recessed place formed from a frame member and the edge part of a bracket. CONSTITUTION:Through the rear suspension supporting bracket 10 of a scooter type vehicle is fixed between the front edges of the left and right frame members 11, the bracket 10 is formed in curved form in nearly parallel to the shape curved in rearward projecting form in plane view of the rear part of a helmet accommodation chamber 12. While, the left and right frame members 11 are extended to the position close to the left and right rear parts of the helmet accommodation chamber 12, and both the edges of the bracket 10 is fitting-fixed at the front edge of each frame member 11. A rear suspension supporting part 13 installed on the bracket 10 is positioned in a recess 14 formed by the front edge side part of one frame member 11 and the edge part of the bracket 10 and set so as to slightly project into an equipment accommodation space from the curved top part 10a of the bracket 10.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a frame for a scooter type vehicle.

(Prior Art) In a scooter type vehicle, as shown in FIG. 3, a helmet storage chamber 2 having a substantially oval planar shape is provided at the bottom of a seat 1, and a helmet can be stored by opening the seat 1 upward. Some models have a box-type frame structure that allows for

On the other hand, a swing arm 5 of a power unit 4, which supports the rear wheel 3 and has a built-in transmission mechanism for transmitting rotation from the engine to the rear wheel, is pivotally supported at the bottom of the scooter's body, and this swing arm 5 is connected to the rear suspension. 6 is used as a buffer.

Conventionally, as shown in the plan view in FIG. 4, the rear suspension support bracket 7 that connects the upper end of the rear suspension 6 is a straight line fixed between the left and right frame members 8 in the rear part of the helmet storage chamber 2. With a structure like
A rear suspension support part 9 is provided at the end thereof, and the upper end of the rear suspension 6 is attached to this support part 9. A space S behind this bracket 7 is used as a space for storing equipment such as a tank.

(Problems to be Solved by the Invention) In the frame structure of the conventional scooter type vehicle described above, the rear part of the helmet storage chamber 2 is used as the storage space S for tanks and other equipment.
When used as a rear suspension support bracket 7, the rear suspension support bracket 7 is located linearly in the vehicle width direction at the rear of the helmet storage chamber 2, so there is no space S for storing equipment.
The volume has been greatly reduced. In addition, the rear suspension support part 9 is further a storage space S.
Since it protrudes inward, there is a problem in that the layout for housing the equipment is not easy.

The present invention was made in consideration of the above-mentioned circumstances, and an object of the present invention is to provide a frame for a scooter type vehicle that can provide a large storage space for equipment without changing the support position of the rear suspension. .

[Structure of the invention]

(Means for Solving the Problems) In order to solve the problems of the above-mentioned prior art, a frame for a scooter type vehicle according to the present invention provides rear suspension support in a frame for a scooter type vehicle having a helmet storage chamber under the seat. A bracket is curved in the vehicle width direction so as to be substantially parallel to the rear shape of the helmet storage chamber, and the ends of the bracket are fixed to the front ends of a frame member extending immediately to the left and right rear portions of the helmet storage chamber, The rear suspension support portion of the bracket is positioned within a recess formed by the frame member and the end portion of the bracket.

(Function) The rear suspension support bracket is curved to follow the shape of the rear part of the helmet storage compartment, and the rear suspension support part is located in the recess formed by the frame member and the end of the bracket. It does not protrude into the equipment storage space at the rear of the tank, and does not interfere with the layout of equipment such as tanks stored in this space.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

The rear suspension support bracket 10 is fixed between the front ends of the left and right frame members 11 and 11, and is approximately parallel to the rearwardly curved shape when viewed from the rear plane of the helmet storage chamber 12. It is curved and arranged close to the helmet storage chamber 12.

On the other hand, the left and right frame members 11.11 extend to a position approaching the rear left and right sides of the helmet storage chamber 12, and both ends of the bracket 10 are fitted and fixed to the front ends of these frame members 11.11. is bracket 10
It is located a distance L forward of the curved top portion 10a.

The rear suspension support portion 13 provided on the bracket 10 is located within a recess 14 formed by the front end side of one frame member 11 and the end of the bracket 10, and is slightly smaller than the curved top portion 10a of the bracket 10. It only protrudes into the device storage space 15.

Therefore, the rear suspension support bracket 10
is curved to follow the rear shape of the helmet storage chamber 12, and the rear suspension support portion 13 is curved to follow the rear shape of the helmet storage chamber 12.
1 and the end of the bracket 10, the volume of the equipment storage space 15 at the rear of the helmet storage chamber 12 is not reduced.

〔Effect of the invention〕

As described above, according to the present invention, the rear suspension support bracket and the rear suspension support part provided thereon do not protrude into the equipment storage space, so the volume of this space increases, allowing storage of equipment such as tanks. The space increases, tank capacity increases, and the layout of other equipment increases.

Furthermore, since the bracket is curved, it has higher strength than a conventional straight bracket, increasing the strength of the frame.
