段が得られる。 すなわち、次表の様になる。 The present invention relates to a planetary gear type transmission, and more particularly to a planetary gear type power shift transmission for a vehicle with eight forward speeds and four reverse speeds. Conventionally, as a planetary gear transmission for construction vehicles,
Transmissions with the same number of forward and backward gears, such as 3 forward gears, 3 reverse gears, 4 forward gears, and 4 reverse gears, are used for vehicles that do a lot of forward and backward work, such as bulldozers, and are used for transport vehicles that do a lot of forward work, such as dump trucks. 8 steps, 1 reverse
A transmission with multiple forward speeds, such as six forward speeds and one reverse speed, and one reverse speed is used. The gear configurations of the two types of transmissions described above are completely different, making it difficult to share parts between them. The present invention has been made in view of the above circumstances, and its purpose is to add one row of planetary gear trains to a transmission with four forward speeds and four reverse speeds, thereby increasing the number of forward speeds to eight forward speeds and four reverse speeds.
To provide a planetary gear type transmission which can be used as a gear transmission. Embodiments of the present invention will be described below with reference to the drawings. The input shaft 1 has sun gears 11, 21, 3 of reverse, low-speed forward, and high-speed forward planetary gear trains 10, 20, 30.
1 is provided, and sun gears 41, 5 of 1st speed, 2nd speed, 3rd speed, 4th speed planetary gear train 40, 50, 60, 70
1, 61, and 71 are provided on the output shaft 2. The above-mentioned reverse, low speed forward, high speed forward, 2nd speed, 3rd speed,
4-speed planetary gear train 10, 20, 30, 50, 60,
70 is a planetary gear 12, 22, 32, 52,
62, 72, carrier 13, 23, 33, 53,
63, 73, ring gear 14, 24, 34, 5
4,64,74. The carrier 13 is connected to the fixed side 3 via the first clutch, the ring gear 14 and the carrier 23 are connected, the ring gear 24 is connected to the fixed side 3 via the second clutch, and the ring gear 24 is connected to the fixed side 3 via the second clutch.
4 is connected to the fixed side 3 via the second clutch, and the carrier 23 and the carrier 33 are connected,
The ring gear 34 is connected to the stationary side 3 via a third clutch. Then, the carrier 33 and the carrier 73 are connected, and the carrier 73 and the carrier 63 are connected,
The ring gears 74, 64, and 54 are connected to the fixed side 3 via fourth, fifth, and sixth clutches, respectively, and the ring gear 64 and the carrier 5
3 are connected, and the carrier 53 and sun gear 41 are connected via a seventh clutch. The 4th speed, 3rd speed, 2nd speed, and 1st speed planetary gear train 70,
The stage ratios of 60, 50, and 40 are equal stage ratios Δζ,
The reduction ratio of the high-speed planetary gear train 30 is ζ 30 , and the reduction ratio of the low-speed planetary gear train 20 is ζ 20.
=ζ 30 ×√. As a result, the stage ratio advances by 8 with the stage ratio √
You will get steps. In other words, it will look like the following table.

変速機とすることができる。[Table] Here, the required stage ratio Δζ 1 of the transport work vehicle is 1.3
~1.4, and the required stage ratio Δζ 2 of the forward-reverse work vehicle
is 1.7 to 1.8, but since √ 2 ≒ Δζ 1 , the gear ratio of each speed stage in the illustrated transmission is set to 1.3 to 1.4.
If so, the gear ratio between each speed stage will be approximately 1.7 to 1.8, resulting in a transmission with 8 forward gears and 4 reverse gears for transport work vehicles, and if the high-speed forward planetary gear train 30 is removed, it will be possible to perform forward and reverse work. This is a 4-speed forward and 4-speed reverse transmission for vehicles. In other words, by adding one high-speed forward planetary gear train 30 to a transmission with four forward speeds and four reverse speeds, it becomes a transmission with eight forward speeds and four reverse speeds. Therefore, the parts of the two types of transmissions can be made common. In the present invention, reverse, low-speed forward, and high-speed forward planetary gear trains 10, 20, and 30 are respectively attached to the input shaft 1 in the order of reverse, low-speed forward, and high-speed forward from the input side, and 1st and 2nd speeds are mounted on the output shaft 2 side.・3 speed / 4 speed planetary gear train 40, 50, 60, 70 from the input side ・
They were installed in the order of 3rd speed, 2nd speed, and 1st speed, and the carrier 33 of the high-speed forward planetary gear 30 and the carrier 73 of the 4th speed planetary gear train 70 were connected, so that the forward speed of 8
It becomes a transmission with 4 speeds and 4 reverse speeds, and the high speed forward planetary gear 30 on the input side 1 side leaves the output shaft 2 side unchanged.
If this is removed and the carrier 23 of the low-speed forward planetary gear train 20 is connected to the carrier 73 of the 4-speed planetary gear train 70, a transmission with four forward speeds and four reverse speeds will be obtained. Therefore, by adding one planetary gear train to a transmission with four forward speeds and four reverse speeds, it can be made into a transmission with eight forward speeds and four reverse speeds.
