[0007] The existing seven-speed gearbox appeared nearly half a century ago, and was later simplified to form the existing four-speed gearbox, but since the existing four-speed gearbox was made public thirty years ago, there has been no new one. The side gearbox of the planetary structure scheme, and the side gearbox of the new planetary structure scheme matching the electric drive has not been disclosed

The invention provides a side gearbox with two forward gears and two reverse gears and a corresponding electric transmission device. The side gearbox is used for a bilateral speed-changing and steering transmission of a high-mobility crawler, comprises four planetary lines, a plurality of clutches, a plurality of brakes and a box body, and is provided with the two forward gears and the two reverse gears, and each forward gear, as well as each reverse gear, is provided with two steering gears and has two relatively big prescribed relative steering radiuses. The invention also provides an electric transmission device and a hybrid electric transmission device which are based on the side gear box; no independently arranged steering motor is provided, so that the structure is compact, the control is simple, and a power transmission chamber has relatively high power density. Therefore, according to the invention, the side gearbox with relatively good straight driving performance and steering performance and the electric transmission device with the side gearbox are obtained.
Description
technical field [0001] The present invention relates to the technical field of high-mobility crawler vehicle electric transmission device, and specifically refers to a side gearbox with two forward gears and two reverse gears and a crawler vehicle electric transmission device with the side gearbox. Background technique [0002] During the development of the high-mobility tracked vehicle drive train, a unique double-sided transmission and steering drive train has appeared. Its working principle is as follows: when driving straight, the double-sided The side gearbox is down by one gear; one side of the gearbox is in the brake gear, and the in-situ steering of ρ=0.5 can be realized; when one side of the gearbox is in 1st gear, and the other side of the gearbox is in reverse gear, it can realize -0.5 In situ center steering for <ρ<0.5. This type of double-sided gearbox is installed into the car body from the side transmission hole on the side of the car body, and is conne...
