Background technique
The automobile variable speed transmission is long best with the gear-driven efficiency long-life, and but shift control is difficult to automation, and the combination of two flank of tooth or the separation that are meshed exist impact, and noise is big, quick abrasion.
Hydraulic machine automatic speed changing car has realized that level and smooth self shifter but increases oil consumption, and is seriously polluted.
Metal band type CVT stepless change transmission.Produce owing to frictional force relies on huge impacting force, pressurization device is consuming kinetic energy, and the power that the low life-span short pass of efficient is passed is restricted, speed changer heating temperature rise, user cost height.
The slewing range of above-mentioned various automotive transmissions is less, and its coupling is perfect inadequately, the raising of still needing of power character and Economy.
Gear transmission and stepless change respectively have excellent lacking, and a kind of automatic gearbox for vehicle gear has gear-driven high efficiency, high-power and long-life, has infinite variable speed speed governing steady, slick and sly again, and various road conditions couplings are more perfect, and ride comfort is safe and reliable to operation.
Summary of the invention
A kind of automatic gearbox for vehicle gear is provided, employing progressively increases and decreases into the many of taper arrangement by the number of teeth arranges gear, and principal and subordinate's gear mesh number picks up several to several ten, normal engagement, gearshift need not done the combination or the disengaging of the flank of tooth, has avoided the excessive defective of shift impact and steering force.
From power input earlier through planetary gear set do to advance, reversing or neutral conversion, again by the input spline driving shaft of the planet carrier direct connection speed changer of planetary gear set, adorning many on the driving shaft progressively increases and decreases by the number of teeth and to be arranged in taper driving tooth wheels, the gear ratio of big small gear reaches several times, but the adjacent number of teeth only differs about 5%, differ the 4-6 tooth, owing to cylindric spiral gear, bearing capacity and efficient height are adopted in normal engagement.
Kink and the corresponding output gear schedule of driving gear on the tubular axis that parallels, and every pair of number of teeth is with identical.Lifting speed slowest ratio reaches and picks up many times like this.Each output gear dallies on tubular axis with the bearing in the endoporus, and adjacent rotating speed is approaching, and gearshift is more relaxed.Each output gear endoporus is made many circular arc camber grooves, and respectively has one group of bearing pin correspondence groove and pipe tap by tubular axis enters in the tubular axis inner chamber, and round end is made in inside and outside two terminations of bearing pin, and has saucer spring and pin to be limited in the tubular axis cinclides, the energy radial slippage.After a movement rod in the tubular axis inner chamber and the cam circular arc cylindrical that links thereof contact the inner of a certain group of bearing pin, cam advances bearing pin to be attached in each groove of output gear endoporus, output gear is transmitted this retaining principal and subordinate gear ratio by bearing pin to the power transmission of tubular axis cinclides with rotating speed transmission.Gearshift once more, movement rod are advanced or are retired apart from arriving another station, and the new inboard termination of one group of bearing pin blocking is subjected to the propelling of cam cylindrical, same combination takes place shifted gears output gear and bearing pin thereof are connected with tubular axis, and gearshift is finished, and rotating speed changes.
One group of bearing pin is subjected to the propelling of cam, the combination of generation and output gear endoporus groove or separate, move apart from only 3～4 millimeters, round end bearing pin and circular arc camber groove be slick and sly contact with gradually deciliter, effect of inertia in the rotation of each gear of while, there is continuity each moment, so from combination or separation and the room of the two, be bearing pin when not pushed by cam, tubular axis is in inertia and rotates, and can not produce the impact of transmission.The axial displacement of movement rod can be interrupted or continuously, inserts corresponding the taper hole locking and positioning that respectively keeps off displacement distance on the movement rod by a taper pin that is controlled, earlier controlled taper pin action, and movement rod is done axial displacement then.
Because the rotating speed of adjacent output gear is approaching, make bearing pin break away from front and enter the smooth-going mitigation of exchange process of backstop, this is to be carried out respectively and can be relatively rotated by two groups of bearing pins owing to the bearing pin that breaks away from or contact in new groove combination with groove, there is not mutual interference, breaking away from combine is same advance and retreat process under fast, does not have impact.Thereby the gearshift have slyness, rotating speed is lifting gradually, ride comfort is safe and reliable.
Principal and subordinate's gear is arranged big or small corresponding inverse ratio, raising speed speed ratio i
1=0.25, reduction of speed velocity ratio i
2=5～6, gear ratio R like this
b〉=10～20, realize the optimum Match of various running condition.
Movement rod and cam axial restraint move apart from controlled.Because cam is connected by bearing, contacts heel with rotation with bearing pin.Because one group of bearing pin has 8～12, symmetrical power transmission, the radial force on cam and the movement rod offsets, so the axial advance and retreat of movement rod are light, convenient, laborsaving and energy-conservation, is convenient to automatic control, realizes instructing execution to shift gears at any time by the parameter of travelling.
Camshaft on the movement rod begins the bearing pin of next retaining is advanced to gearshift output gear endoporus groove, the taper pin that just in time is positioned then locking gradually after thickness size should make front break away from fully again.The location taper pin is by electromagnetism or hydraulic control.
The displacement control of movement rod is exactly gear shift control, by hydraulic rod or worm gear, the rotation of gear and the displacement that spiral moves the manipulation movement rod, realizes automatic speed changing by the required acceptance instruction of travelling.
Because when movement rod was axially advanced and retreat, cam, bearing pin, tubular axis and output gear rotated in the same way, enter the quite approaching of adjacent retaining again from certain retaining disengaging, thereby gearshift can be smooth in conjunction with its rotating speed.So the retaining number is close more favourable more, its principal and subordinate's gear is arranged the long cone pulley of suitable steel loop long conical stepless speed variator, reaches lifting speed gradually, and speed change more relaxes.Cone pulley type principal and subordinate gear is arranged, and axially being close to increases the retaining number, has realized the close infinite variable speed slyness that is.
Automatic gearbox for vehicle gear often adopts planetary gear set as connecting with power input guide, as adopt that the dual planetary gear transmission is advanced, the conversion of reversing and neutral, spline driving shaft by planet carrier direct connection speed changer, and it is parallel with tubular axis and semiaxis, compact structure has realized that again all gear pairs adopt cylindric spiral gear often to mesh.
The spline driving shaft is made hollow, and oil pump shaft is passed through, and row's driving gear becomes long cone shape closely to be connected on the spline driving shaft.Tubular axis is important transmission shaft, overcoat one row output gear, and alternate have a little gap.Each output gear is supported on the tubular axis by bearing with endoporus two ends, and the circular arc camber groove is made at the endoporus middle part, often adopts 8～12 teeth groove of hypocycloid.Corresponding to each output gear endoporus groove one group of pipe tap is arranged on the tubular axis, bearing pin is housed in the cinclides, bearing pin is resetted by saucer spring elastic force, and pin is spacing.The amount of movement of bearing pin in the tubular axis cinclides only needs 3～4 millimeters.
Cam is supported on the movement rod by the endoporus bearing, contact and rotation with bearing pin during power transmission, cylindrical is made arc convex surface, make axially advance and retreat, arc convex surface promotes bearing pin gradually, and the active force that one group of bearing pin is subjected to output gear endoporus groove produces counter-force and pushes back on the cam, because the counteracting of each bearing pin power, movement rod axial displacement resistance reduces, and realizes crash change of speed.
Intermediate gear on the tubular axis is transferred to the differential mechanism gear ring, perhaps is delivered to start clutch earlier.Differential gear set is arranged at the speed changer input end, and two semiaxis length are close or equal.
Tubular axis is bearing on the body bearing, and each output gear connects with tubular axis with bearing again, only is subjected to that movement rod and cam thereof advance one group of bearing pin and certain retaining of entering endoporus groove carry-over moment, is exported by tubular axis.Cam can only a propelling that keep off, and the speed change rotating speed can not suddenly change, and it is safer to travel.
The gear of automatic gearbox for vehicle gear adopts the cylinder helical teeth, is good with the multiple tooth number of little modulus.Because gear transmission has efficiently, Gao Cheng plants power, long-life and compactedness, and the range of infinitely variable speeds of friction wheel transmission is big, the better advantage of matching, the two combination, learning from other's strong points to offset one's weaknesses is exactly the characteristic superiority of automatic gearbox for vehicle gear, the high energy-saving and emission-reduction of efficient, the good driving safety of matching is reliable.Automatic gearbox for vehicle gear keeps gear-driven advantage, and overcome be meshed profile of tooth in conjunction with or the entry and exit that separate by slick and sly many curved surface grooves of circular arc in the bore and round end bearing pin reach gearshift, little in conjunction with mobile size, impacting, realize relaxing smooth-going gearshift again near avoided mutual interference to produce with the combination under the speed.Because gear pair often meshes, increase the retaining number near, reducing of axial dimension between the gear mesh, reach two-phase O retaining rotating speed near and the increase of lifting slewing range.In addition, can shift gears at any time in the parking and significantly improve starting performance, overcome big resistance with the big torque of the slow-speed of revolution and improve cross-country power.Keep normal engagement to reduce impact and improve gear life and machine life, improve driving comfort and Security with wearing and tearing.Also have shift speed change not have spontaneous carrying out, accident rate reduces, and progressively lifting speed has been avoided because of handling the error peril.Automatic gearbox for vehicle gear can also adopt two controls, improves safety guarantee.
