Abstract

A rolling type vehicle includes a pair of left and right arm members supported in a swingable manner by a vehicle body on inner sides in the transverse direction for supporting a pair of left and right front wheels in a steerable manner on outer sides in the transverse direction, respectively. A shock absorber support arm of which a central portion in the transverse direction is supported in a swingable manner by the vehicle body and is connected to the pair of left and right arm members through shock absorber units on outer sides in the transverse direction, respectively. The left and right shock absorber units are disposed on outer circumference sides of turning trajectories of the pair of left and right front wheels, respectively.

First claim

What is claimed is:

1. A rolling vehicle including a pair of left and right front wheels and a vehicle body capable of rolling, the rolling vehicle comprising:
a pair of left and right arm members supported in a swingable manner by the vehicle body on inner sides in a transverse direction for supporting the pair of left and right front wheels in a steerable manner on outer sides in the transverse direction, respectively; and
a shock absorber support arm of which a central portion in the transverse direction is supported in a swingable manner by the vehicle body, said shock absorber support arm being connected to the pair of left and right arm members through shock absorber units on outer sides in the transverse direction, respectively;
wherein the left and right shock absorber units are disposed on outer circumference sides of turning trajectories of the pair of left and right front wheels, respectively, and center axes of the left and right shock absorber units are disposed rearwardly of the pair of left and right front wheels in a side view.

2. The rolling vehicle according to claim 1 , wherein the shock absorber support arm includes left and right arm portions extending, while deviating outward in the transverse direction and rearward, from a shaft support portion supported by the vehicle body in a swingable manner.

3. The rolling vehicle according to claim 2 , wherein the left and right shock absorber units each have a sub tank; and
the sub tanks are disposed on outer sides of the left and right shock absorber units in the transverse direction.

4. The rolling vehicle according to claim 2 , wherein an engine as a drive source of the vehicle is disposed rearwardly of the pair of left and right front wheels, and
the left and right shock absorber units are disposed adjacent to the engine.

5. The rolling vehicle according to claim 1 , wherein the left and right shock absorber units each have a sub tank; and
the sub tanks are disposed on outer sides of the left and right shock absorber units in the transverse direction.

6. The rolling vehicle according to claim 5 , wherein an engine as a drive source of the vehicle is disposed rearwardly of the pair of left and right front wheels, and
the left and right shock absorber units are disposed adjacent to the engine.

7. The rolling vehicle according to claim 1 , wherein an engine as a drive source of the vehicle is disposed rearwardly of the pair of left and right front wheels, and
the left and right shock absorber units are disposed adjacent to the engine.

8. A suspension system for a vehicle comprising:
a pair of left and right arm members supported in a swingable manner on a vehicle body on inner sides in a transverse direction for supporting a pair of left and right front wheels in a steerable manner on outer sides in the transverse direction, respectively; and
a shock absorber support arm having a central portion in the transverse direction supported in a swingable manner by the vehicle body, said shock absorber support arm being connected to the pair of left and right arm members through shock absorber units on outer sides in the transverse direction, respectively;
said left and right shock absorber units being disposed on outer circumference sides of turning trajectories of the pair of left and right front wheels, respectively, and center axes of the left and right shock absorber units are disposed rearwardly of the pair of left and right front wheels in a side view.

9. The suspension system for a vehicle according to claim 8 , wherein the shock absorber support arm includes left and right arm portions extending, while deviating outward in the transverse direction and rearward, from a shaft support portion supported by the vehicle body in a swingable manner.

10. The suspension system for a vehicle according to claim 9 , wherein an engine as a drive source of the vehicle is disposed rearwardly of the pair of left and right front wheels, and
the left and right shock absorber units are disposed adjacent to the engine.

11. The suspension system for a vehicle according to claim 8 , wherein the left and right shock absorber units each have a sub tank; and
the sub tanks are disposed on outer sides of the left and right shock absorber units in the transverse direction.

12. The suspension system for a vehicle according to claim 8 , wherein an engine as a drive source of the vehicle is disposed rearwardly of the pair of left and right front wheels, and
the left and right shock absorber units are disposed adjacent to the engine.
