Description
Technical field
The utility model relates to a kind of power-shift gear box that is used for electric motor car.
Background technique
Speed threshold electronic three, the four-wheel wagon car is divided into one, two retainings usually, and a retaining speed is low, and two retaining speed are high.One, two retaining driving gears often mesh with one, two retaining driven gears respectively.In the past electronic three, four-wheel wagon combine through the driven gear of stirring intermediary's original paper and, two retainings, and impact noise is big, is difficult for gearshift, damages gear easily, and the life-span such as lacks at shortcoming.
The model utility content
The utility model technical problem to be solved is: the power-shift gear box that can be used for electric motor car that a kind of simple in structure, long service life is provided.
The utility model solves the technological scheme that its technical problem adopted: a kind of power-shift gear box that is used for electric motor car; Comprise second gear, jack shaft and the tooth-like free wheel device of a retaining; Power shift gear, second gear and the tooth-like free wheel device of a retaining are sleeved on the jack shaft, and power shift gear is between second gear and the tooth-like free wheel device of a retaining, and second gear, the tooth-like free wheel device of a retaining cooperate with jack shaft is rotatable; Power shift gear drives slippingly with intermediate gear shaft and cooperates; The slippage of the power shift gear left and right sides, the inner ring with the tooth-like free wheel device of a retaining meshes respectively, perhaps meshes with second gear.
The tooth-like free wheel device of one retaining comprises the driven gear and first straight-tooth gear of surmounting of a retaining, and one keeps off the driven geared sleeve that surmounts on first straight-tooth gear, and fixes with first straight-tooth gear, and first straight-tooth gear is enclosed within on the jack shaft, cooperates with jack shaft is rotatable; Second gear comprises the two retaining driven gear and second straight-tooth gears, and two retaining driven gears are enclosed within on second straight-tooth gear, and fix with second straight-tooth gear, and second straight-tooth gear is enclosed within on the jack shaft, cooperates with jack shaft is rotatable; The slippage of the power shift gear left and right sides with the engagement of first straight-tooth gear, is perhaps meshed with second straight-tooth gear respectively.
Power shift gear drives slippingly through spur gear with jack shaft and cooperates.
The driven gear that surmounts of one retaining is fixed through the flat key and first straight-tooth gear, and two retaining driven gears are fixed through the flat key and second straight-tooth gear.
Also be with intermediate gear on the jack shaft, intermediate gear drives with jack shaft and cooperates, outwards outputting power.
The beneficial effect of the utility model is: the utility model is the power-shift gear box that tooth-like clutch and overdrive clutch combine, and has overcome free wheel device and has surmounted unidirectional shortcoming, also overcomes the function that tooth-like clutch can not be unidirectional simultaneously.The utility model gearshift is applied on the electro-tricycle not only can realize the gearshift of advancing, and can also realize the retaining that falls back; And overcome the electro-tricycle descending or, protected the effect of motor owing to the inrush current of inertia to the motor generation.Because descending can drive the motor quick rotation when keeping off slowly, produce inrush current, there has been free wheel device just can reach reverse idle effect, keep off the descending motor so slowly and just can not rotate, the effect of protection motor.And this power-shift gear box gearshift is convenient, simple in structure, easy accessibility, long service life, and manufacturing cost and use cost is low.

Among the figure, 1. jack shaft 2. one keeps off the driven gear that surmounts, 3. first straight-tooth gear, 4. power shift gear, 5. second straight-tooth gear, 6. two retaining driven gear, 7. intermediate gear, 8. flat keys.
Embodiment
Like Fig. 1,2,3,4, shown in 5 and 6; A kind of power-shift gear box that is used for electric motor car comprises second gear, jack shaft 1 and the tooth-like free wheel device of a retaining, and power shift gear 4, second gear and the tooth-like free wheel device of a retaining are sleeved on the jack shaft 1; Power shift gear 4 is between second gear and the tooth-like free wheel device of a retaining; Second gear, tooth-like free wheel device of a retaining and 1 rotatable cooperation of jack shaft, power shift gear 4 drives slippingly through spur gear with jack shaft 1 and cooperates, power shift gear 4 left and right sides slippages; Inner ring with the tooth-like free wheel device of a retaining meshes respectively, perhaps meshes with second gear.
The tooth-like free wheel device 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 jack shaft 1, with 1 rotatable cooperation of jack 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 jack shaft 1; With 1 rotatable cooperation of jack 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.
Also be with intermediate gear 7 on the jack shaft 1, intermediate gear 7 is fixing through flat key 8 with jack shaft 1, outwards outputting power.
The utility model working procedure is such, when electro-tricycle need be stirred power shift gear when two retainings go; Itself and second straight-tooth gear 5 are meshed; Power shift gear rotation under the drive of two retaining driven gears 6, jack 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 jack shaft and rotates in the driven drive that surmounts gear 2 of retaining rotation down, and then drives the intermediate gear rotation.
The utility model is the power-shift gear box that tooth-like clutch and overdrive clutch combine, and 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 free wheel device; 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 jack 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 jack 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 jack shaft also can be fallen fast, and it is very little that the relative velocity of shifting gears so also can become, easily gearshift.
