Abstract

PURPOSE:To improve space efficiency and characteristics by constituting an upper arm from an I-arm and connecting a knuckle arm or a trailing arm onto the lower edge of a damper. CONSTITUTION:One edge of an upper arm 3 constituted of an I-arm is connected to the upper edge of a knuckle arm 1, and each edge of two lower arms 4 and 4 is connected to the lower edge of said knuckle arm 1. The front edge of a trailing arm 5 is connected to a chassis frame through a bush 6, and the rear edge is rotatably connected to the knuckle arm 1 through a bearing 7. A rubber bush 9 equipped with a pipe is installed in projecting form onto the lower part of the knuckle arm 1, and the lower edge of a hydraulic damper 10 is connected. With such constitution, the upper space of a rear suspension is occupied by the upper arm 3 and the damper 10 only, and the space efficiency is improved. Further, each torsion of the upper and lower arms is prevented, and characteristics can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an independent rear suspension.

In the rear suspension as shown in FIG. 7, there is a problem in that the space efficiency is reduced because the rear suspension is constructed of a construction part that connects the brake device to the trailing arm 105 so as not to adversely affect the suspension characteristics.

The present invention has been made to effectively solve the above problems.
The objective is to provide an independent rear suspension that is highly space efficient and exhibits excellent characteristics.

To achieve such an object, the present invention provides an independent rear suspension consisting of an upper arm, a lower arm, and a trailing arm, which are connected to the upper and lower ends of the knuckle arm, respectively.
The damper is characterized in that the lower end of the damper is connected to the knuck/l/arm or the trailing arm.

A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view of a rear suspension according to the present invention, FIG. 2 is a side view thereof, and FIG. 3 is a rear view thereof.

This is an independently suspended rear suspension knuckle arm shown in FIGS. 1 to 3, and the upper end of this knuckle arm 1 has a
One end of the upper arm 3, which is made up of one arm of a book,
Further, one end of each of two lower arms 4, 4 is connected to the lower end.

These upper arm 3 and lower arm 4,
4. The other end of each is connected to a vehicle body frame (not shown).

On the other hand, numeral 5 in the figure is a trailing arm made of a plate spring or the like that has high rigidity in the vertical direction of the vehicle body and sufficient elasticity in the width direction of the vehicle body. It is connected to the vehicle body frame through a bearing 7 so as to be able to swing up and down, and its rear end is rotatably connected to the knuckle arm 1 through a bearing 7.

A spindle 8 that pivotally supports the rear wheel 2 is protruded from the rear end of the trailing arm 5.

By the way, at the bottom of the knuckle arm 1 there is a rubber bushing 9 with a tube, which has an axis in the longitudinal direction of the vehicle body, as shown in FIG.
is provided protrudingly, and the lower end of a hydraulic damper 10 is connected to the rubber bush 9 as shown in the figure. The upper end of the hydraulic damper 10 is connected to the vehicle body via a mount rubber 11.

Although not shown, a brake is coupled to the trailing arm 5.

The upper arm 3 is composed of an arm, and the upper space of the rear suspension is occupied only by the upper arm 3 and the damper 10. Therefore, the space can be used rationally, and space efficiency is significantly improved.

Furthermore, since the lower end of the damper 10 is connected to the knuckle arm 1 via the bush 9, twisting of the upper arm 3, lower arms 4, etc. is prevented, and therefore the suspension characteristics are extremely good.

In addition, this rear suspension exhibits characteristics similar to those of a double wishbone type suspension, and also exhibits a large anti-lift effect during braking.

Next, a modified embodiment of the present invention will be described with reference to FIGS. 4 to 6.

FIG. 4 is a perspective view of the rear suspension according to this modified embodiment, FIG. 5 is a side view of the same, and FIG. 6 is a partially cutaway rear view of the same. In these figures, the rear suspension according to the first embodiment ( The same members as those shown in FIGS. 1 to 3 are denoted by the same reference numerals, and descriptions of these same members will be omitted.

Incidentally, in this modified embodiment, the lower end of the hydraulic damper 10 is connected to the trailing arm 1 side via a bearing block 12, and the intermediate portion thereof is connected to the knuckle arm 1 via a link 13.

In this modified embodiment as well, effects similar to those obtained in the first embodiment can be obtained.

As is clear from the above description, according to the present invention, the upper arm is composed of one I-arm, and the lower end of the damper is connected to the knuckle arm or trailing arm, thereby improving the space efficiency around the rear suspension. It is possible to improve the characteristics of the rear suspension.
