Below in conjunction with Fig. 1---7 explanations are according to the details and the service condition of the concrete device that the utility model proposes.

As can be seen from Figure 1, be that the glider that main body is formed is installed on the position of former installation low gear cliding gear in the BJ2020 transfer case of automobile with interior wheel 6 shown in Figure 2, ratchet 8 with foreign steamer shown in Figure 3 10, ratchet 9.Interior wheel 6 is in the foreign steamer 10 front end chambeies, and they respectively have one group of ratchet that can cooperatively interact, ratchet; The splined hole of foreign steamer 10, interior wheel 6 respectively with output shaft 3, with often nibble spline housing 5 splines that are connected as a single entity of wheel and be connected, stir joystick, by shift fork 11 drive gliders, glider can be on output shaft 3 and spline housing 5 axial slip.

When automobile need be started to walk to overtake, joint gradually along with power-transfer clutch, engine power passes to constant mesh gear by part-time case driving gear, countershaft-gear again after becoming fortune device speed change, as shown in Figure 1, wheel 6 rotated in constant mesh gear drove by the spline housing 5 that fuses with it, as shown in Figure 4, when interior wheel turns over certain angle, ratchet 8 embeds in the teeth groove of foreign steamer 10, and interior wheel 6 drives foreign steamer 10 rotations and drives transmission device by output shaft, drives automobile to overtake.

When automobile need slide, the pin pine tar behind the door, driving engine is in idling, under the effect of inertia or descending potential energy, automobile still travels at a relatively high speed, as shown in Figure 5, this moment and the rotating speed of drive wheel bonded assembly foreign steamer 10 be higher than with the driving engine bonded assembly in the rotating speed of wheel 6, ratchet 8 slips on foreign steamer 10 chamber inner periphery alveolar surfaces; Ratchet 9 outwards opens under action of centrifugal force, and driving engine is to the transmission automatic cutout between drive wheel, automobile slide.

Reversing automobile, the principle of work of glider as shown in Figure 6, before the starting, in the one group of ratchet 9 that distributes on foreign steamer 10 circumference, be in ratchet bottom under the effect of gravity (also can utilize elastic force) of top, when hanging the reverse gear starting, interior wheel conter clockwise turns over an angle, wheel teeth groove in ratchet 9 embeds, the power of wheel 6 passes to foreign steamer 10 and output shaft and drives automobile by transmission device through ratchet 9 and falls back and travel in reaching.

During running car, the anxious throttle of receiving, wheel is subjected to driving engine to pin down deceleration immediately in the glider, the inertia owing to travel, slow down slower with drive wheel bonded assembly foreign steamer, outer wheel speed is higher than interior wheel speed, foreign steamer and interior wheel one generation speed are poor as shown in Figure 5, and drive wheel is stirred shifter bar this moment to the transmission automatic cutout between driving engine, be easy to a speed change tooth cover or gear and retreat to neutral gear from gear, under the effect of synchro, can make the very fast formation constant speed of main follower again, can successfully change to gear, so the automobile of glider is housed, do not operate the clutch, as long as just gear shift successfully of pine tar door (directly gear shift when sliding automatically).

Automobile is stagnation of movement on the slope, and trend advancing slip or that the back slips is arranged, but no matter be advancing slip or the back slide, opposite with cruising, foreign steamer becomes driving wheel in the glider, and interior wheel becomes follower.The automobile stagnation of movement, outer ratchet is the bottom under gravity or elastic force effect, and as driving wheel, the foreign steamer cw turns over an angle, wheel teeth groove in ratchet 9 just embeds; The foreign steamer conter clockwise turns over an angle, and ratchet 8 just embeds the foreign steamer teeth groove.The automobile stagnation of movement, the two-way rotation of foreign steamer all is subjected to pining down of driving engine behind the gearing in, can satisfy the requirement of driving engine assistance braking when stopping like this.Because of loading onto glider, automobile stagnation of movement driving engine on the slope can not assisted braking and be caused the advancing slip or back slide of automobile

When running car forbids sliding the highway section at muddy, ice and snow and other, needs are controlled automobile is not slided automatically, stir joystick (former part-time case high and low shift joystick) this moment, glider is stirred (position by Fig. 1 is allocated to Fig. 7 position) forward by shift fork 11, spline housing 5 engagements on glider foreign steamer 10 rear end splined holes and the constant mesh gear, the floating constant mesh gear that changes fuses with output shaft by outer gear teeth cover, and power is directly exported through output shaft by constant mesh gear.

BJ2020 automobile and similar vehicle brake system are equipped with vacuum booster unit at present, automobile is in a single day flame-out in the process of sliding, after using two to three brakings, braking effect will weaken greatly, the automobile that has vacuum booster brake device for this class, installing should be at engine intake manifold to installing a vacuum cylinder that has check valve between vacuum booster pump behind the Glider automatic, and an engine oil pressure is installed on the driving engine oil main line is crossed low annunciator, by lead oil pressure being crossed low annunciator is connected with miniature buzzer phone in the operator's compartment, in the automobile slide process, motivation is in idling operation, in case flame-out be difficult for discovering, this moment the engine oil drops, oil pressure is crossed the low annunciator closing of contact, miniature buzzer phone in the operator's compartment just sends audible indication, can remind chaufeur to note; The effect that vacuum cylinder is installed is in sliding, and driving engine is not worked suddenly and can be carried out having several times the braking of afterburning effect more under the situation of (stopping working).
