Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a suspension mounting structure, and more particularly to an upper mounting structure such as a double wishbone suspension of an automobile.

(Prior Art) A double wishbone suspension system for an automobile
Usually, a shock absorber and a coil spring externally fitted to the shock absorber are arranged between a pair of upper and lower control arms composed of an upper arm and a lower arm, and each of these parts is mounted on a vehicle body in a proper state in a limited space. There is a need. In order to facilitate the mounting work of the above-mentioned respective parts, as shown in Japanese Utility Model Laid-Open No. 61-182307, for example, a bracket having a mounting portion for the upper arm and a mounting hole for the shock absorber is provided, and the upper arm and the bracket are provided. It is known that after the shock absorber is attached, the bracket is attached to the vehicle body so as to eliminate restrictions on work when attaching the upper arm and the like.

However, in the conventional device having the above configuration, since all the loads input from the shock absorber are supported by the bracket, it is necessary to configure this bracket so as to withstand the load. There is a problem that the structure becomes complicated and the weight increases.

(Object of the Invention) The present invention provides a suspension mounting structure that can simplify the mounting work without complicating the structure and can stably support the load input from the shock absorber. To do.

(Structure of the Invention) The present invention relates to a suspension mounting structure including an upper arm and a shock absorber. An arm bracket having an insertion hole through which the upper shaft is inserted is provided, and the upper shaft of the shock absorber is attached to the vehicle body frame with the arm bracket interposed between the upper mounting portion of the shock absorber and the vehicle body frame. It will be.

According to the above configuration, the tip end portion of the upper arm located on the inner side of the vehicle body is easily attached to the vehicle body frame via the arm bracket, and the load input from the shock absorber is supported by the vehicle body frame. .

(Embodiment) FIGS. 1 to 3 show an upper mounting structure of a double wishbone suspension according to the present invention.
The suspension includes an upper arm 1, a shock absorber 2, a knuckle arm 3, and an arm bracket 4. The upper arm 1 is composed of a connecting portion 6 that is connected to the upper end portion of the arm 3 by a knucking through a ball joint 5, and a pair of arm portions 7 that extend inward from the connecting portion 6. A rubber bush 9 and a spacer 10 are attached to the tip portion 8 of the arm portion 7, and a mounting bolt 11 is inserted therethrough. The tip portions 8 of the two arm portions 7 are swingably attached to the support portions 13 formed by a pair of attachment plates 12 provided on both sides of the tip portions of the arm bracket 4 by the attachment bolts 11.

The arm bracket 4 is attached to the lower surface of the vehicle body frame 16 by the attachment bolts 15, and the arm bracket 4 and the vehicle body frame 16 respectively have insertion holes 18 and 19 through which the upper shaft 17 of the shock absorber 2 is inserted. It is formed at the position where Then, the retainer 20 is provided below the insertion hole 18 of the arm bracket 4.
With the rubber bush 22 and the retainer 23 disposed above the insertion hole 19 of the vehicle body frame 16, the upper shaft 17 and the spacer 24 of the shock absorber 2 are inserted therethrough,
By screwing the nut 25 onto the upper end threaded portion 17a of the upper shaft 17, the upper shaft 17 of the shock absorber 2 can be mounted with the arm bracket 4 interposed between the upper mounting portion of the shock absorber 2 and the vehicle body frame 16. It is attached to the body frame 16.

A bump stopper 26 is fitted onto the upper shaft 17 of the shock absorber 2, and a support bracket 27 for supporting the upper end of the bump stopper 26 is provided on the upper shaft 1.
It is attached in a state of being sandwiched by a flange portion 28 and a nut 29 provided on the device 7. A retainer 30 that supports the lower end of the rubber bush 21 is disposed above the nut 29. Further, on the lower side of the support bracket 27, there is formed a locking portion 32 for locking the upper end portion of the coil spring 31 arranged outside the shock absorber 2.

As described above, the tip portion 8 of the upper arm 1 located on the inner side of the vehicle body is previously attached to the support portion 13 of the arm bracket 4, and the tip portion 8 of the upper arm 1 is connected to the vehicle body frame 16 via the arm bracket 4. Therefore, the complicated work of mounting the tip end portion 8 of the upper arm 1 on the vehicle body frame 16 in a swingable state in a limited space is not required, and the mounting work can be simplified.

Since the upper shaft 17 of the shock absorber 2 is directly attached to the vehicle body frame 16 together with the arm bracket 4, the load input from the shock absorber 2 can be supported by both the arm bracket 4 and the vehicle body frame 16. Therefore, a stable supporting state can be obtained. Moreover, in the above embodiment, the arm bracket 4 is mounted in a state of being sandwiched between the vehicle body frame 16 and the upper mounting portion of the shock absorber 2. Therefore, the mounting of the arm bracket 4 to the vehicle body frame 16 is performed by the upper mounting portion of the shock absorber 2. The strength can be improved.

Although the mounting structure for the front wheel suspension has been described in the above embodiment, the structure of the present invention can be applied to the mounting structure for the rear wheel suspension as long as the structure includes the upper arm and the shock absorber.

(Effects of the Invention) As described above, the present invention is provided with the support portion for swingably supporting the tip end portion of the upper arm located on the inner side of the vehicle body, and the insertion hole through which the upper shaft of the shock absorber is inserted. In the suspension mounting structure that simplifies the mounting work by configuring the above-described arm bracket to mount the tip portion of the upper arm to the vehicle body frame via the arm bracket,
The upper shaft of the shock absorber is inserted into the insertion hole of the arm bracket, and the upper shaft of the shock absorber is attached to the vehicle body frame with the arm bracket interposed between the upper mounting portion of the shock absorber and the vehicle body frame. With this configuration, the load input from the shock absorber can be stably supported by both the arm bracket and the vehicle body frame. Therefore, there is an advantage that the arm bracket need not be strong enough to withstand the load, and the structure of the arm bracket can be simplified.
