Abstract

(57) [Summary] [Object] An object of the present invention is to provide an equalizer beam shaft which allows the shaft to be inserted from the enlarged portion side of the axle housing without lowering the ground clearance. In a vehicle suspension device having an equalizer beam 4, a notch 5a is provided in a threaded portion of an end portion of a shaft 5 that fixes the equalizer beam 4 and the axle housing 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle suspension device having an equalizer beam.

[0002]

[Prior art]

 For example, in FIG. 2, there is known a suspension device in which lower parts of two axes 1, 1 are fixed by an equalizer beam 4 and a shaft 5 supported by a beam saddle 10 and upper parts are supported by torque rods 9, 9.

[0003]

[Problems to be solved by the device]

 However, in the above technique, the length of the shaft that fixes the equalizer beam and the axle housing is limited due to the size of the enlarged portion 1a that accommodates the final drive of the axle housing and the layout of the tire and the like.

Referring also to FIG. 3, when the shaft 5 cannot be inserted from the side of the enlarged portion 1a because it interferes with the enlarged portion 1a, the position of the shaft 5 is lowered by extending the bracket 3 downward. However, lowering the shaft lowers the ground clearance.

Therefore, an object of the present invention is to provide an equalizer beam shaft in which the shaft can be inserted from the enlarged portion side of the axle housing without lowering the ground clearance.

[0006]

[Means for Solving the Problems]

 According to the present invention, in a vehicle suspension device having an equalizer beam, a notch is provided in a screw portion at a shaft end for fixing the equalizer beam and the axle housing.

[0007]

In the equalizer beam shaft configured as described above, since the thread portion at the end portion of the equalizer beam shaft is provided with the notch, it does not interfere with the enlarged portion of the axle housing when the shaft is inserted.

[0008]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In the drawings, members having the same function are designated by the same reference numerals, and description thereof will be omitted.

In FIG. 1, a bracket 3 is attached to the axle housing 1, and an equalizer beam 4 is fixed to the bracket 3 with a shaft 6 by a nut 6.

Then, a pin (not shown) is attached to the pin hole 7.

A notch 5 a is provided in the threaded portion at the end of the shaft 5.

Therefore, even if the enlarged portion 1a of the axle housing is close to the bracket 3, since the notch 5a is provided, the shaft 5 can be inserted and assembled from this side as shown by A.

Further, even if the screw portion is reduced due to the notch, the screw does not loosen because of the pin.

[0015]

[Effect of device]

 Since the present invention is configured as described above, the enlarged portion of the axle housing is close to the bracket, and the shaft of the equalizer beam can be assembled even if it needs to be inserted from the enlarged portion side.

Therefore, it is not necessary to lower the minimum ground clearance without increasing the cost.
