Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a power unit side support structure for a support rod used in a remote control floor shift type speed change operation mechanism.

(Prior art) Conventionally, as a gear shift operation mechanism using a support rod, for example, "Nitsun Service Bulletin No. 440"
No. 98 of ``No.'' (June 1981, published by Nissan Motor Co., Ltd.)
Those listed on page 108 are known.

As shown in FIGS. 7 and 8, the power unit side support structure of the support rod of this conventional speed change operation mechanism includes a support rod bracket that supports a support rod 03 on a power unit side bracket 02 of a rear power unit mount 01. A portion 04 was integrally extended by embossing, and a rubber bush 05 provided at the end of the support rod 03 was fixed to the support rod bracket portion 04 with bolts 06 and nuts 07.

In addition, in Figures 7 and 8, 08 is the mount insulator, 09 is the vehicle body side bracket,
010 is a buffer bracket, and 011 is a power unit fixing hole.

(Problem to be solved by the invention) However, in such a conventional support rod support structure, the power unit side bracket 02, which is fixed in a cantilever manner with respect to the power unit, is formed on the free end side. Since the support rod 03 was supported by the support rod bracket part 04, there was a problem that the support part swayed greatly against the load applied from the support rod 03 side or from the power unit side, and the support rigidity was low. .

Due to this problem, the driver loses the sense of firmness when operating the control lever, and the vibration amplitude from the power unit is amplified and transmitted to the vehicle body.

(Means for solving the problem) The present invention was made with the purpose of solving the above-mentioned problems, and to achieve this purpose, the present invention incorporates a power unit including a transmission into a vehicle body. A power unit side bracket fixed to the power unit side of the power mount of the power unit mount that elastically supports the power unit, an end face part fixed to the power unit separately from the power unit side bracket, and an end face part fixed to the power unit side bracket of the power unit side bracket. A support rod bracket consisting of a lateral extending portion for connection and fixation is integrally provided, and is arranged approximately parallel to the control rod that transmits the operating force to the control lever to the transmission of the power unit, and one end is connected to the control lever. The power unit side end of the support rod, which is supported on the side and whose other end is supported on the power unit side, is supported by the lateral extending part of the support rod bracket.

(Function) In the support rod support structure of the present invention, first,
A support rod bracket is integrally provided on the power unit side bracket of the power unit mount that elastically supports the power unit including the transmission against the vehicle body.

The power unit side bracket is fixed to the power unit, and apart from this fixation, the end surface of the support rod bracket is fixed.

On the other hand, the support rod, which is placed almost parallel to the control rod that transmits the operating force on the control lever to the transmission of the power unit, has one end supported on the control lever side and the other end on the power unit side. are supported on the lateral extensions of the support rod bracket.

Here, the lateral extending part of the support rod bracket is a part that connects and fixes the end face part fixed to the power unit to the power unit side bracket, so that the support rod bracket is fixed to the power unit on both sides.

Therefore, the support rod is supported by the lateral extending portion of the support rod bracket, which is fixed to the power unit on both sides.
Support rigidity is increased compared to the conventional case of supporting in a cantilevered fixed state.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.
Furthermore, in describing this example, we will use a model with a horizontally mounted engine and a manual transmission.
Let us take as an example the support rod support structure for the remote control floor shift type gear change operation function applied to front-wheel drive vehicles.

First, the configuration of the first embodiment will be explained.

As shown in FIG. 4, the remote control floor shift type speed change operation mechanism B to which the support rod support structure A of the embodiment is applied includes a control lever 1, a lever socket 2, a control rod 3, a holder rubber 4, a support rod 5, and a rubber bush. It is equipped with 6.

The power unit side bracket 11 used in the structure of the first embodiment includes a left side plate 111, a right side plate 112, and a connecting plate 113, as shown in FIG.

The left side plate 111 and the right side plate 112 have substantially the same shape and are connected by a connecting plate 113.

The right side plate 112 has a mount insulator attachment hole 112a and a working hole 112b.

A square nut 111a is fixed to the left side plate 111 at a hole position corresponding to the mount insulator attachment hole 112a, and a working hole 1 is fixed at a position corresponding to the working hole 112b.
11b is opened. Furthermore, a bolt hole 111c for fixing to the power unit 12 is bored in the upper part of the left side plate 111.

Furthermore, a pin 13, a reinforcing plate 14, and a support rod bracket 15 are welded and fixed to the left side plate 111 so as to protrude from the outer surface of the left side plate 111.

The reinforcing plate 14 is welded and fixed between the pin 13 and the support rod bracket 15.
The aim is to improve the mounting strength of the structure and block the effects of flying stones and heat.

The support bracket 15 has a lateral lower surface extension portion 151 on which the support rod 5 is supported, an end surface portion 152 fixed to the power unit 12, and a lateral front surface extension portion 153 that covers the front surface of the bracket. It is roughly cup-shaped. still,
Bolt holes 151a and 151b for fixing the support rod 5 are formed in the side lower surface extending portion 151, and bolt holes 152 for fixing the support rod 5 to the power unit 12 are formed in the end surface portion 152.

The power unit side bracket 11 is attached to the power unit 12 (clutch housing, etc.) by fixing bolt holes 111 as shown in FIG.
c, 152a and pin 13, bolt 1
6, 17, and 18.

Further, as shown in FIGS. 1 and 2, the power unit side bracket 11 is supported by a vehicle body member 20 via a mount insulator 19 and a vehicle body side bracket (not shown).

As shown in FIGS. 1 and 2, the support rod 5 connects the bushing bracket 21 to the side lower surface extending portion 15 of the support rod bracket 15.
The bushing bracket 21, which has a U-shaped cross section, is fixed to the fixing holes 151a and 151b opened in the rubber bushing 6 with bolts 22 and 23 and nuts 24 and 25, and then the bushing bracket 21, which has a U-shaped cross section, is fixed to the fixing holes 151a and 151b opened in the rubber bushing 6 with bolts 22 and 23 and nuts 24 and 25.
6. By supporting both ends with nuts 27,
It is supported by a power unit side bracket 11.

Next, the operation of the first embodiment will be explained.

First, a third bracket is attached to the power unit side bracket 11 of the rear power unit mount 10 that elastically supports the power unit 12 including the transmission against the vehicle body.
As shown in the figure, support rod bracket 15
are integrally provided by welding.

Then, for the power unit 12, the first
As shown in the figure, power unit side bracket 1
1 is fixed by fixing bolts 16 and 18, and in addition to this fixing, the end face portion 152 of the support rod bracket 15 is fixed by a fixing bolt 17.

On the other hand, as shown in FIG. 4, the support rod 5, which is arranged approximately parallel to the control rod 3 that transmits the operating force on the control lever 1 to the transmission of the power unit 12, has one end 5a facing the control lever 1. The power unit side end, which is the other end 5b, is supported by the lateral lower surface extending portion 151 of the support rod bracket 15, as shown in FIGS. 1 and 2.

Here, the lateral lower surface extending portion 151 of the support rod bracket 15 is a portion that connects and fixes the end surface portion 152 fixed to the power unit 12 to the power unit side bracket 11, as shown in FIG. Then, the power unit 12 is held and fixed on both sides.

Therefore, the support rod 5 is supported by the side lower surface extending portion 151 of the support rod bracket 15 which is fixed on both sides with respect to the power unit 12, and is not fixed on a cantilever as in the conventional case. Support rigidity is increased compared to the case of supporting.

As explained above, the support rod support structure A of the first embodiment provides the following effects.

Since the support rod 5 is supported by the support rod bracket 15 which is fixed at both ends, a high support rigidity is obtained, which ensures a firm feeling when operating the control lever 1, and also provides a secure grip on the power unit. 12
There is no need to amplify the vibration amplitude from the side and transmit it to the control lever 1 side.

Since the rubber bushing 6 of the support rod 5 is supported at both ends by the bushing bracket 21,
The support rigidity of the support rod 5 becomes extremely high due to the synergistic effect with the double-support fixation described in .

After subassembling the bushing bracket 21 and the rubber bushing 6, they are assembled to the side lower surface extending portion 151 of the support rod bracket 15, so that the holes of both can be easily aligned visually from above the vehicle. .

Since the support rod bracket 15 is formed into a substantially cup shape, the support rod bracket 15 can be used as a place for parts such as nuts and washers during assembly.

Next, a second embodiment shown in FIG. 5 and FIG. 6 will be described.

This second embodiment includes a side upper surface extending portion 154 welded to the power unit side bracket 11 and an end surface portion 155 extending from the side upper surface extending portion 154.
This is an example using a support rod bracket 15 constructed by.

Incidentally, although the specific shape is different, the same components as in the first embodiment are given the same reference numerals and the description thereof will be omitted.

Further, the operation of the second embodiment is similar to that of the first embodiment, and the effects described above can be obtained except for the above-mentioned effects.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention may be modified without departing from the gist of the present invention. included.

(Effects of the invention) As explained above, in the support rod support structure of the invention, the power unit side bracket has an end face part fixed to the power unit separately from the power unit side bracket, and the end face part A support rod bracket is integrally provided with a lateral extending portion that connects and fixes the support rod to the power unit side bracket, and is arranged approximately parallel to the control rod that transmits the operating force to the control lever to the transmission of the power unit. Since the end of the support rod on the power unit side is supported by the lateral extension of the support rod bracket, the supporting rigidity of the support rod on the power unit side is increased, and a firm feeling is ensured when operating the control lever. , it is possible to reduce the amplitude of vibrations transmitted from the power unit side to the control lever side.
