Fig. 2 is the structural representation of the mechanics of planet steering box compressed-air control device of the present utility model;
Fig. 3 is that left steering clutch part in Fig. 2 is from the fundamental diagram viewed from side-looking;
Fig. 4 is the schematic diagram of existing System of Tracked Vehicle Transmission System.
Detailed description of the invention
As shown in Figure 4, existing System of Tracked Vehicle Transmission System comprises driving engine 101, transmission gearbox 102, power-transfer clutch 103, change speed gear box 104, the power that driving engine 101 produces passes to the power input shaft of change speed gear box 104 by power-transfer clutch 103, power from change speed gear box out after power be divided into two-way, pass to left and right two planet steering boxs 105 respectively, the power of each planet steering box 105 exports from driving wheel 107 through being positioned at after its outer side speed reducer 106 slows down respectively; Planet steering box 105 structure of both sides is identical, is arranged symmetrically with, and the planet steering box 105 in left side comprises planet row K

2" be high-speed side crawler track speeds, " V
g2" be crawler track speeds when I turns to, " V
0" be straight-line travelling speed." divide " and represent that lockup clutch is separated or releasing of brake, " conjunction " represents that lockup clutch engages or drg is braked completely." part " represents that part brake is braked.
Straight-line travelling is divided into high-speed straight-line to travel and speed straight line travels, when high-speed straight-line travels, lockup clutch engages, and size brake collar unclamps, and power directly passes to side speed reducer by change speed gear box, planet steering box integral-rotation, transmitting ratio is 1 (table 1 sequence number 1), when speed straight line travels, both sides lockup clutch is separated, little brake collar braking, large brake collar unclamps, planet steering box has fixing reduction ratio, and (speed ratio is (k+1)/k, k is that Parameter of Planet Bars perseverance is greater than 1), both sides driving wheel speed is the same, for speed straight line travels (table 1 sequence number 2), this situation lockup clutch is separated, due to the existence of viscous moment, can not work long hours under lockup clutch separation case, compared with moving with high-speed straight-line, now transmitting ratio is (k+1)/k, be greater than 1, now the speed of a motor vehicle reduces, tractive force increases, this state can at large resistance location short-period used, vehicle traction is increased in the situation of not shifting gears.During Vehicular turn mode of operation part can be divided into be separated turn to, be separated turn to, primary importance turns to and skid steer (also making the second place turn to).Part is separated low speed side lockup clutch part when turning to and is separated, and high-speed side lockup clutch combines completely, when ground drag is greater than low speed side tractive force, low speed side speed reduces, Vehicular turn, and this turning to is called for part separation turns to, now Turning radius is relevant with ground drag, when normal road, because ground drag is relatively little, it is few that low speed side speed reduces, Turning radius is excessive, and thisly to turn to because latch portion combines, wear smooth merit is large, uses less when vehicle travels; When separation turns to, low speed side lockup clutch is separated completely, high-speed side lockup clutch engages, and now low speed side reduces by the speed of action of ground drag, Vehicular turn, this turning to often uses in high vehicle speeds low-angle correction direction, when primary importance turns to, low speed side lockup clutch is separated, little brake, large releasing of brake, low speed side planet steering gear ratio is (k+1)/k, crawler track speeds reduces, and vehicle carries out first and turns to, and Turning radius is R
g2; During skid steer, during low speed side, low speed side lockup clutch is separated, and little releasing of brake, large brake, now low speed side crawler track speeds is 0, and Vehicular turn radius is B/2 (B is width of tracks).
