8. owing to can not seal fully, must reserve engine starting and driver behavior space, mud, water and dust easily enter in the railway carriage.
The purpose of this utility model is to provide a kind of prior art above shortcomings that can overcome, and is applicable to the engine back fixed straight coupling type backing and driving device of motor tricycle.
Above-mentioned purpose of the present utility model is to realize by such technical scheme, it is a kind of engine back fixed straight coupling type backing and driving device, comprise gear box casing, driving engine, diff, by I, II axle, advancement mechanism, neutral gear mechanism, reverse gear mechanism that semiaxis, catcher, main driven gear and shift fork constitute, wherein be suspended on the bridge bracket of back driving engine by coupler with transmission of power to the I axle that is positioned at change speed gear box; It is characterized in that: an I axle left side, the right side is set with the I shaft gear of band joint pawl, has the catcher of splined with it in the middle of the I axle, have the II shaft gear and the driving gear that connect with male splines on the II axle, catcher is in the drive bottom left of shift fork, moving right can be respectively and the joint pawl engagement of the I shaft gear at its two ends, make with I shaft gear ingear II axle on gear rotation and make driving gear and the driven gear that is installed on the differential gear box rotates, or by with I shaft gear ingear semiaxis on carrier gear and II shaft gear engagement, and make driving gear and the driven gear that is installed on the differential gear box rotates, power transmission to diff, is arrived a left side to power distribution by diff again, right axle shaft promptly drives wheel revolutions.
Said structure of the present utility model can further specify by the embodiment that accompanying drawing provides.
Accompanying drawing is a structure echelon sectional view of the present utility model.
Referring to accompanying drawing: the engine back fixed straight coupling type backing and driving device among the figure, comprise gear box casing, driving engine 1, diff 18, by I, II axle 3 and 14, semiaxis 11, catcher 6, main driven gear 15 and 16 and shift fork 7 advancement mechanism, neutral gear mechanism, the reverse gear mechanism that constitute, wherein be suspended on driving engine on the bridge bracket of back by coupler 2 with transmission of power to being positioned on the change speed gear box I axle 3; It is characterized in that: the left side of I axle, the right side is set with the I shaft gear 4 and 9 of band joint pawl, has the catcher 6 of splined with it in the middle of the I axle, have the II shaft gear 12 that connects with male splines and 13 and driving gear 15 on the II axle 14, catcher is in the drive bottom left of shift fork 7, move right and to mesh with the I shaft gear 4 at its two ends or 9 joint pawl respectively, or make with I shaft gear 4 ingear II axles on gear 13 rotation and make driving gear and the driven gear 16 that is installed on the differential gear box rotates, or by with I shaft gear 9 ingear semiaxis 11 on carrier gear 10 and 12 engagements of II shaft gear, nibble wheel and rotate and make driving gear and be installed in driven on the differential gear box, power transmission to diff 18, is arrived a left side to power distribution by diff again, right axle shaft 17 and 19 promptly drives wheel 20 rotations.
In said structure, diff is positioned at spherical shell 21, and spherical shell and change speed gear box are connected as one, and the place of wearing axle on the casing is added with seal ring.
Principle of work of the present utility model is such:
One. advancement function: be suspended on the driving engine 1 of back on the bridge bracket by drive coupling 2 power transmission to I axle 3, I axle left and right side sky is overlapping the I shaft gear 4 and the I shaft gear 9 of band joint pawl, is shaped on spline in the middle of the I axle, catcher 6 is contained in the spline segment of I axle.Three-wheel vehicle advances when travelling, stage clip 8 will take over 6 push to the right side the time, joint pawl engagement with I shaft gear 4, the gear teeth 4 and 13 engagements of II shaft gear, transmit power to (at this moment the I axle is opposite with the hand of rotation of II axle) on the II axle 14, the driving gear 15 that is fixed on the II axle is meshed with hard-wired driven big gear wheel 16 on the differential gear box, gear mesh on this gear and the diff, and transmit power on the diff 18, again by diff power distribution on left half axle 17 and right axle shaft 19, left and right sides semiaxis promptly drives wheel 20 rotation, thereby realizing that three-wheel vehicle advances travels.
Two. neutral gear: when pilot control pull bar 5 when left moves to Neutral Position, catcher 6 is mediated, no power takeoff, car can not travel.
Three. reverse gear function: when pilot control pull bar 5 continues to move to when reversing gear the position to left, the catcher 6 and the joint pawl of I shaft gear 9 are meshed, the gear teeth and empty carrier gear 10 engagements that are enclosed within on the semiaxis 11, carrier gear and II shaft gear 12 engagements that are fixed on the II axle, thereby power transmission to the II axle, the I axle identical with II axle hand of rotation (with underdrive with advance travel identical).Reach the purpose of reverse gear, promptly realized retreating of car.
