The specific embodiment
As illustrated in fig. 1 and 2; A kind of integral type speed change differential driving rear axle; Comprise left and right axletree 14,15, input shaft 11, change retaining assembly 12, differential assembly 13, rear axle housing body 16 and brake equipment 17, brake equipment 17 is installed on the rear axle housing body 16; Left and right axletree 14,15 is installed in the rear axle housing body 16; Differential assembly 13 drives with left and right axletree 14,15 and cooperates, and change retaining assembly 12, input shaft 11, differential assembly 13 are installed in the actuator housing, and are installed on the rear axle housing body 16 through actuator housing.Actuator housing is assembled by left and right aluminum hull 9,10.Left and right aluminum hull 9,10 adopts bolted to connect; Between the two with paper washer and be coated with sealant in case leak-stopping is oily; The connection mode of left and right aluminum hull 9,10 and rear axle housing body 16 with left and right aluminum hull 9, connect identically between 10, also be coated with simultaneously and prevent leakage of oil with sealant.
Become retaining assembly 12 and comprise second gear, tween drive shaft 1 and the tooth-like overriding clutch of a retaining; Power shift gear 4, second gear and the tooth-like overriding clutch of a retaining are sleeved on the tween drive shaft 1; Power shift gear 4 is between second gear and the tooth-like overriding clutch of a retaining, and second gear, a tooth-like overriding clutch of retaining and tween drive shaft 1 turn and cooperate, and power shift gear 4 drives slippingly through straight gear with tween drive shaft 1 and cooperates; Power shift gear 4 left and right sides slippages; With the inner ring engagement of the tooth-like overriding clutch of a retaining, perhaps with the second gear engagement, input shaft 11 cooperates with outer ring, the second gear driving of the tooth-like overriding clutch of a retaining through gear respectively; Also be with intermediate gear 7 on the tween drive shaft 1, tween drive shaft 1 drives with differential assembly 13 through intermediate gear 7 and cooperates.
The tooth-like overriding clutch of one retaining comprises the driven gear 2 and first straight-tooth gear 3 of surmounting of a retaining; The driven gear 2 that surmounts of one retaining is enclosed within on first straight-tooth gear 3; The driven gear 2 that surmounts of one retaining is fixed through the flat key 8 and first straight-tooth gear 3; First straight-tooth gear 3 is enclosed within on the tween drive shaft 1, with 1 rotatable cooperation of tween drive shaft; Second gear comprises the two retaining driven gear 6 and second straight-tooth gears 5; Two retaining driven gears 6 are enclosed within on second straight-tooth gear 5, and two retaining driven gears 6 are fixing through the flat key 8 and second straight-tooth gear 5, and second straight-tooth gear 5 is enclosed within on the tween drive shaft 1; With 1 rotatable cooperation of tween drive shaft; Power shift gear 4 left and right sides slippages are respectively with 3 engagements of first straight-tooth gear, perhaps with 5 engagements of second straight-tooth gear.
The utility model working process is such, and motor driving shaft drives the input shaft 11 of back axle, and input shaft 11 keeps off the speed change that assembly 12 is realized differential assembly 13 through becoming, thereby realizes axletree is realized speed change.Need when two retainings go, stir power shift gear when electro-tricycle, itself and second straight-tooth gear 5 are meshed, power shift gear rotation under the drive of two retaining driven gears 6, tween drive shaft and power shift gear rotate synchronously, drive the intermediate gear rotation.Need when a retaining goes, stir power shift gear when electro-tricycle, make it break away from second straight-tooth gear 5; Combine with first straight-tooth gear 3; Power shift gear drives tween drive shaft and rotates in the driven drive that surmounts gear 2 of retaining rotation down, and then drives the intermediate gear rotation.
The power-shift gear box that the utility model adopts tooth-like clutch and overdrive clutch to combine has overcome the shortcoming that tooth is beaten in tooth-like gearshift.Tooth-like as everybody knows combination only relative velocity be zero or relative velocity very little in just easily, otherwise can beat tooth, damage gear easily.This power-shift gear box; When two retainings change a retaining; Because first straight-tooth gear 3 and the driven gear 2 that surmounts of a retaining are combined into a tooth-like overriding clutch; Have only the driven speed that surmounts the speed of gear 2 greater than first straight-tooth gear 3 of a retaining, first straight-tooth gear 3 just can receive torsion and one to keep off that driven to surmount gear 2 synchronous.When two retainings change retaining time, the speed of tween drive shaft is greater than the driven speed that surmounts gear 2 of a retaining, and promptly the driven gear 2 that surmounts of first straight-tooth gear 3 and a retaining separates and do not stress, and is basic synchronous with tween drive shaft, is easy to like this shift gears.Be to cut off motor power in the time of owing to the electro-tricycle gearshift, when a retaining shifts into second, the motor outage, motor speed can be fallen very rapidly, and the speed of tween drive shaft also can be fallen fast, and it is very little that the relative velocity of shifting gears so also can become, easily gearshift.
