Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a support structure for a support bracket that is included in a vehicle transmission and supports supported members such as a throttle cable.

[Prior art]

Generally, in automatic transmissions for vehicles, the transmission is connected to the oil pan of the transmission and supported via a stay on one side of the transmission case, as shown in Japanese Utility Model Publication No. 51-6625. It is equipped with an oil filler tube that extends to a predetermined position in the engine room, and is used for checking the amount of oil in the oil pan, lubrication, etc. In addition, in this type of transmission, although not shown in the above publication, in order to link the operation of the engine's injection pump and the accelerator pedal, there is a mechanism for supporting supported members such as a throttle cable that connects the two. Equipped with a support bracket. The support bracket is fixed to one side of the transmission case and extends outwardly so as to support the supported member at its outer end.

[Problem that the invention attempts to solve]

By the way, since vibrations from the engine are transmitted to such a support bracket, when the rigidity supporting the support bracket is low, the vibration of the support bracket itself increases, vibrates the supported member, and accelerates the decline in strength of the support bracket. There is a problem. For this reason, it is desirable to increase the support rigidity of the support bracket to suppress its vibrations, but in order to cope with this, if one or more support members are newly adopted to support the support bracket, the number of parts will increase. Alternatively, if the thickness of the support bracket is increased, a problem arises in that the weight increases.

[Means to solve the problem]

The present invention has been made to solve these problems, and in the above-mentioned type of transmission, one of the stays fixed to the oil filler tube is fixed to one side of the case, and the other stay is fixed to one side of the case. The structure is characterized in that the stay is fixed to the intermediate portion of the support bracket, and the support bracket is supported by the case and the oil filler tube.

[Functions and effects of the idea]

As a result, in the present invention, it is possible to increase the support rigidity of the support bracket by effectively utilizing the oil filler tube that extends in a cross-shape in the vibration direction of the support bracket in the oil filler tube and the existing stays that support the tube. The number of parts increases to increase support rigidity,
Or the weight of the support bracket is not increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings, in which a part of a transaxle of an automatic transmission employing the support structure of the present invention is schematically shown. In this automatic transmission, an oil pan 12 is provided at the bottom of the transaxle case 11.
A connecting pipe 13 is attached to one side of the oil pan 12. One end of this connecting pipe 13 is connected to the oil pan 12.
The lower end of the oil filler tube 21 is fitted into and connected to the other end.

In addition, in this automatic transmission, case 11
A support bracket 23 is fixed to the engine 14 side end portion of the case 11 by a plurality of bolts 22, 22 for attaching the case 11 to the engine 14.

Therefore, this support bracket 23 is attached to case 1.
1, a slightly thicker board portion 23a that is fixed to one side of the board and bends outward to protrude; and this board portion 23a.
The arm portion 23 is welded to the front surface of the outer protrusion portion 23a1 and protrudes further outward, and has approximately the same thickness as the conventional plate.
b, and the outer tube of the throttle cable 15 is fixed and supported at the outer end of the arm portion 23b.

On the other hand, the oil filler tube 21 consists of a first tube part 21a that extends upward at a small angle on one side of the case 11, and a second tube part 21b that bends and extends further upward from the upper end of the first tube part 21a. A first stay 24a is welded to the lower end of the first tube portion 21a, and a second stay 24b is welded to the upper end thereof. The first stay 24a extends along one side of the case 11 and is fixed to the case 11, and the second stay 24b extends to the rear surface of the outer protrusion 23a1 on the base plate 23a of the support bracket 23 and is attached to the middle part of the support bracket 23. It is fixed to the same rear surface via a bolt 23a2. As a result, the oil filler tube 21 is supported by the case 11 and the base plate 23a of the support bracket 23 via the stays 24a and 24b, and the support bracket 23 is supported by the case 11 and the oil filler tube via the bolts 22 and the second stay 24b. It is supported by the first tube portion 21a of the filler tube 21.

In such a support structure, the support bracket 2
3 is supported by the case 11 as well as the first tube portion 21a of the oil filler tube 21.
is also supported by the first tube portion 2.
1a extends transversely to the direction of vibration of the support bracket 23. For this reason, the support bracket 2
The support rigidity of the engine 14 is higher than that of the conventional model.
The vibrations of the support bracket 23 due to the vibrations of the throttle cable 15 are suppressed, and the vibrations of the throttle cable 15 are suppressed. As a result, transmission of vibration to the accelerator pedal connected to the throttle cable 15 can be suppressed,
The operating feeling of the accelerator pedal can be improved. Further, it is possible to prevent the strength of the support bracket 23 from decreasing due to vibration.

Note that since the second stay 24b that supports the support bracket 23 on the oil filler tube 21 is an existing stay that supports the oil filler tube 21 on the case 11, the number of parts increases in this support structure. Moreover, since not all the plates of the support bracket 23 are made thick, the weight of the support bracket 23 does not increase significantly.

In this embodiment, the support bracket 23 is constructed of a slightly thicker base plate portion 23a and a slightly thinner arm portion 23b. Therefore, the rigidity of the support bracket 23 can be increased without significantly increasing the weight of the support bracket 23.
Its support rigidity can be increased.
