Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a baffle plate mounting structure for a manual transmission.

[0002]

2. Description of the Related Art Lubricating oil for lubricating a gear mechanism is stored in a casing of a manual transmission, and sudden start,
A baffle plate is mounted on the bottom surface of the casing in order to prevent the oil surface from tilting due to acceleration generated during sudden acceleration. Conventionally, a gear mechanism is incorporated in a casing with a baffle plate attached to the bottom of the casing.

[0003]

In this method, it is necessary to shorten the height of the baffle plate so that the baffle plate does not interfere when the gear mechanism is assembled. In particular, in a multi-speed manual transmission such as a 6-speed manual transmission, it is necessary to increase the diameter of the counter shaft in order to secure the strength and rigidity of the shaft, and the height of the baffle plate is greatly limited. However, if the height of the baffle plate is shortened, the ability to prevent the oil surface inclination due to acceleration deteriorates,
If the oil surface inclination becomes steep, lubrication failure will occur in the gear mechanism,
There arises a problem that seizure and damage of gears occur. In order to ensure the lubrication of the gear mechanism, it is necessary to increase the amount of oil in the casing, but increasing the amount of oil increases the total weight of the transmission.

[0004]

As a means for solving the above conventional problems, the present invention provides a baffle plate (5A, 5A, an adapter plate (4) in which a gear mechanism (3) is incorporated in advance.
The baffle plate (5A, 5B) of the transmission (1), in which the baffle plate substrate (6) with the (5B) attached is attached, and then the casing (2) is attached to the adapter plate (4).
A mounting structure is provided. It is desirable that the baffle plates (5A, 5B) are attached to the baffle plate substrate (6) two in the front and rear, and further, the two baffle plates (5A, 5B) are attached from the front and rear edges of the peripheral plate (5C). It is desirable that they are integrated by being bent.

[0005]

In the present invention, the baffle plate substrate (6) having the baffle plates (5A, 5B) attached to the adapter plate (4) in which the gear mechanism (3) is incorporated in advance is attached, and then the adapter plate (4) is attached. Since the casing (2) is attached to (), the height of the baffle plates (5A, 5B) can be set high, and the ability to prevent the oil level inclination due to acceleration can be sufficiently secured, and The problem of interference when gears are incorporated is eliminated.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described with reference to an embodiment shown in FIGS. 1 to 4, as shown in FIGS.
The gear mechanism (3) is installed in the center of the adapter plate (4) to which the casing (2) of the 6-speed manual transmission (1) is attached, and the lower front side of the adapter plate (4) is A baffle plate board (6) with two baffle plates (5A, 5B) is attached, and the casing is installed on the front side of the adapter plate (4).
(2) is attached, and the front cover (7) is attached to the front side of the casing (2).

As shown in FIG. 3, the two baffle plates (5A, 5B) are integrated by bending the front and rear edges of the peripheral plate (5C) by sheet metal working or the like. Attach the integrated baffle plate unit (5) to the front part of the upper surface of the baffle plate substrate (6) as shown in FIG. Two bolt holes (61) are provided at the rear end of the baffle plate substrate (6) (see FIGS. 3 and 4).
The baffle plate substrate (6) is fastened to the adapter plate (4) by bolts (8) through the bolt holes (61) (see FIGS. 1 and 2).

In the present invention, as described above, the gear mechanism is previously prepared.
Attach the baffle plate board (6) with the baffle plates (5A, 5B) attached to the adapter plate (4) incorporating (3), and then the casing to the adapter plate (4).
Since (2) is assembled, the problem of baffle plate interference when assembling gears is eliminated, and the baffle plate
The height of (5A, 5B) can be secured sufficiently. For example, in this embodiment, the height of the baffle plate (5A) is 40
mm (previously 20 mm), baffle plate (5B) height is 4
The height is set to 0 mm (20 mm in the past), and this height is sufficient to suppress the inclination of the oil surface due to acceleration.

[0009]

According to the present invention, the height of the baffle plate is ensured, and the oil level inclination of the lubricating oil in the casing due to the acceleration generated when the vehicle is suddenly started or suddenly accelerated is effectively suppressed. Can be done.
