Detailed description of the invention
Below in conjunction with the accompanying drawings the embodiment of this assisted electric traveling car driving axis is described in further detail:
This assisted electric traveling car driving axis is made up of central siphon assembly 1, brake band hub assembly 2, half axle assembly 3, speed reducer assembly 4, and central siphon assembly about 1 two ends are symmetrically welded with floor pan assembly 5；Brake band hub assembly 2 it is welded with outside floor pan assembly 5, half axle assembly 3 it is welded with inside floor pan assembly 5, half axle assembly 3 is connected with brake band hub assembly 2, and half axle assembly 3 is connected with the outfan of speed reducer assembly 4, and the input of speed reducer assembly 4 is connected with motor；Central siphon assembly 1 is made up of bend pipe 101, base plate 102, reinforcement 103, spring block 104, reinforcing ring 105, shock absorber support 106, spool support 107.
Distance between two pieces of base plates 102 at described central siphon assembly 1 two ends is 1384mm.
Distance between two spring block 104 centre bores of described central siphon assembly 1 is 1060mm.
The described distance between two brake band hub assemblies 2 is 1560mm.(seeing Fig. 1～2)
This assisted electric traveling car driving axis is the 90 ° of angles of power turnover transmitted by brake band hub assembly 2 actuating device, the direction of transfer of change power, after simultaneously being reduced rotating speed by speed reducer assembly 4, increased torque, distribute to left and right half axle assembly 3 and driving wheel through differential mechanism.
The specific works process of this assisted electric traveling car driving axis is as follows:
The motor of electric motor car is connected with the input of the main reducing gear of speed reducer assembly 4, drives driving gear to rotate, and driving gear drives the driven gear of the main reducing gear of speed reducer assembly 4 to rotate, thus reaches increase torque and drop slow-revving effect.Driven gear is fixed on differential carrier, the spline of half axle assembly 3 end is connected with the axle shaft gear spline at differential assembly two ends, differential assembly drives semiaxis to rotate, the semiaxis other end is bolted on wheel hub, the moment of torsion transmitted by differential mechanism passes to driving wheel, so that electric motor car travels.
The operation principle of summary differential assembly: when a, automobile straight-line travelling, the driven wheel of differential of main reducing gear drives differential carrier to rotate, differential mechanism difference drives planetary gear axle to rotate, planetary gear axle drives planetary gear revolution, axle shaft gear is synchronized rotating Vortex under planetary clamping, and now, planetary gear only revolves round the sun, not rotation, left and right wheels and rotating speed are equal to the rotating speed of driven wheel of differential.When b, automobile turning, planetary gear, while revolution, creates rotation, i.e. around the rotation of planet gear shaft, causes the increase of side axle shaft gear rotating speed, and the reduction of opposite side axle shaft gear rotating speed, both sides wheel rotates with different rotating speeds.Now, the rotating speed that the rotating speed that single wheel increases reduces equal to opposite side wheel.C, after two driving wheels are propped, wheel lift, if rotate side wheel, the then synchronized rotation of opposite side wheel opposite direction, at this moment, planetary gear the rotation in differential mechanism, not revolving round the sun, both sides axle shaft gear rotates in a reverse direction, thus drives the both sides synchronized rotation of wheel opposite direction.
When electric motor car needs braking, brake pedal, by a series of transmissions, promote to grind poor block and press to brake disc, the frictional force of generation makes brake disc stop the rotation, and brake disc is fixing with wheel hub to be connected, thus reaches the effect of driving wheel braking.Loosening the brake, mill difference block keeps gap with brake disc, and frictional force disappears, brake release.
The mentality of designing of this assisted electric traveling car driving axis is as follows: compared with existing electric motor car driving bridge assembly, speed reducer assembly 4 and central siphon assembly 1 separate, are each independently mounted on vehicle frame, meanwhile, central siphon assembly 1 organically combines with speed reducer assembly 4 further through floor pan assembly 5；The advantage of this design is: electric motor car also can ensure harmony when travelling when using independent suspension.Central siphon 101 uses 40Cr steel pipe, can ensure the intensity of central siphon 101 well and increase minimum ground clearance, can reduce again electric motor car quality.Its speed reducer assembly 4 selects 1028 series matured products, and its speed ratio had not only ensured that automobile had optimal dynamic property but also can control the consumption of energy of electric automobile, and made driving member stable working, and noise is little.Brake band hub assembly 2 uses disc type brake, less compared to its size of drum brake and quality, and its usefulness is the most more stable.
The central siphon i.e. axle case assy of assembly 1(of this electric automobile drive axle assembly) the most more flexible, central siphon assembly 1 is designed to the bend pipe 101 having drop so that it is stress evenly, is processed simple and convenient, greatly reduced processing cost.
The above is presently preferred embodiments of the present invention, the example above explanation not flesh and blood to the present invention makees any pro forma restriction, person of an ordinary skill in the technical field's any simple modification that above detailed description of the invention has been made by the technical spirit of the foundation present invention after having read this specification or deformation, and the technology contents possibly also with the disclosure above is changed or is modified to the Equivalent embodiments of equivalent variations, all still fall within the range of technical solution of the present invention, without departing from the spirit and scope of the invention.
