ガバナーバルブのガバナーシャフトの抜け止め装置に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for preventing the governor shaft of a governor valve from falling off in an automatic transmission.

させていた。Conventionally, in order to prevent the governor shaft that rotates the governor valve from coming off from the transmission, an annular groove for preventing the governor shaft from coming off is provided in addition to an annular groove for oil delivery, and a through hole is drilled in the transmission case. A pin is press-fitted into a through hole from the outside of the transmission case, and the tip of the pin is inserted into and engaged with the annular groove of the shaft.

コスト高となるといつた欠点があつた。However, when the pin is press-fitted in this manner, burrs may appear at the opening of the through-hole on the inner surface of the transmission case, causing the shaft to stick. Therefore, in order to prevent the occurrence of burrs, as shown in Fig. 1, a pin c having a threaded portion for preventing it from coming off is inserted into the annular groove b for oil delivery of the governor shaft a attached to the governor body f. There is also a screw threaded into a screw hole formed in the screw hole from the outside, but in this case, thread machining and an O-ring e to prevent oil leakage from the screw portion are required, resulting in high cost.

る。In the figure, 1 is a transmission case, 2 is a torque converter housing, 3 is a gasket interposed between the transmission case 1 and the torque converter housing 2, 4 is a governor body with a primary governor valve and a secondary governor valve provided inside, 5 is a governor shaft that is integrally attached to the governor body,
5a and 5b are annular grooves for oil transfer between the oil passages 14a and 14b formed in the transmission case 1 and the governor valve in the governor body 4; 6 is an original pinion fixed to the tip of the governor shaft 5; 7 is this pinion 6 A ring gear meshes with the output shaft of an automatic transmission (not shown) and rotates together with the output shaft.
8 is provided integrally with the output shaft, and when parking,
9 is the governor shaft support part lb of the transmission case 1, which is used to prevent the vehicle from moving.
A thrust washer interposed between the upper end and the bottom plate 11 of the governor body 4, 10 a governor cap, 1
1 is an O-ring inserted between the governor valve holding part 1c of the transmission case 1 and the governor cap 10, and 12 is a snap ring for fixing the governor cap 10 to the governor valve holding part 1c. In the case of the governor valve configured as described above, the ring gear 7 of the output shaft driven by the engine
By rotating the governor shaft 5 via the pinion 6, a rotational force is applied to the primary governor valve and the secondary governor valve in the governor body, and the line pressure from the oil passage 14b is adjusted to the vehicle speed by the two governor valves. The governor pressure regulated accordingly is output to the oil passage 14a. Note that the structures of the primary governor valve and the secondary governor valve are well known, and therefore will not be described here. In the present invention, oil passages 14a, 14b communicate with annular grooves 5a, 5b for oil delivery of the governor shaft 5 via oil holes 13a, 13b.
As shown in FIG. 2 and FIG. 4, the contact surface 1a of the transmission case 1 with the torque converter housing 2
A pin 1 is formed by casting to be more concave and is inserted into the annular structure 5b to prevent the governor shaft 5 from coming off.
5 is bored into the transmission case 1 in the form of a blind hole from within the oil passage 14b. After inserting the tip of the pin 15 into the pin hole 16 through the annular groove 5b of the governor shaft 5, the torque converter housing 2
The joint surface 2a of the converter housing 2 is formed in such a shape that when the converter housing 2 is assembled to the transmission case 1 via the gasket 3, the rear end of the pin 15 hits the gasket 3 and the pin 15 does not come out. In this embodiment, the insertion hole 16 for the pin 15 was provided on the side of the oil passage 14b that communicates with the annular groove 5b;
It may be provided on the a side. Also, the length of the pin 15 is the length of the pin hole 16.
It is preferable that the rear end of the pin 15 abuts against the joint surface of the torque converter housing 2 or the gasket 3 in this part when the pin 15 is inserted into the housing. The device of the present invention requires only the blind pin hole 16 to be drilled in the oil passage 14a1 or 14b as described above, so mechanical processing is very simple and easy.
またピン１５はピン孔１６に対して圧入する必要がない
ため、ピン孔開口部にばりが出てガバナーシヤフトをス
テイツクさせる恐れもない。さらにピン孔１６はケース
の外部と全く絶縁されているため、ピン孔１６からケー
ス外部への油洩れは完全になくなる。Further, since the pin 15 does not need to be press-fitted into the pin hole 16, there is no fear that burrs will appear at the opening of the pin hole and cause the governor shaft to become stuck. Furthermore, since the pin hole 16 is completely insulated from the outside of the case, oil leakage from the pin hole 16 to the outside of the case is completely eliminated.
