Abstract
The utility model discloses a gearbox for a light-type automobile, which is designed as a second-class transmission structure comprising four shafts and eleven gears. The gearbox fully utilities the oblique gear transmission to obtain the power output of six forwards and one turn back, of which, the hard core column roller bearing that the first axis drives through the outer ring is set on the housing. One end of the second shaft is mounted on the inner hole of the first shaft by the hard core bearing and the other end is supported on the housing through bearing that the first axis drives. The different gears are sleeved to the second shaft through the roller bearing. The synchrotron of the different gears is fixed on the second shaft through the spline on the gear seat; the middle shaft is supported on the housing through the column roller bearing. The different gears on the middle shaft are relatively meshed with the different gears on the second shaft one and one; the inertia wheel spindle is directly supported on the housing. The inertia wheel is mounted on the inertia wheel spindle. The forward gear maximum speed ratio of the utility model is 7.617and the reverse gear one 7.059. All the gearboxes are the synchrotron gears except the first forward gear. The first forward gear and the reverse gear use to change the gear with the meshing sleeve.
Description
Technical field
The utility model relates to a kind of light vapor vehicular transmission, especially relates to the improvement to its structure, and the helical gear transmission is all adopted in the transmission of four 11 gear secondarys, can realize six last astern power outputs.
Background technique
Light vehicle transmission of the prior art mostly is five speed transmission greatly, exist power character deficiency or speed ratio rank excessive, bring problems such as gear shift difficulty, oil consumption are big easily, and one grade of gear is essentially the spur gear engagement, meshing performance exists not enough, has not satisfied the growth requirement of Light-duty Vehicle.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the deficiency of above-mentioned existence, and a kind of compact structure is provided, gear is many, ratio coverage is big, coupling is reasonable, meshing performance is good, low price, can satisfy the automotive transmission of Light-duty Vehicle growth requirement.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of light vapor vehicular transmission, comprise housing, wherein first full roller bearing by outer astragal stop ring is arranged on the housing, an end of second is arranged on by full type roller bearing on first the endoporus, the other end is bearing on the housing by the full roller bearing of outer astragal stop ring, each shifting gear is enclosed within on second by the needle bearing sky, and each grade synchronizer is fixed on second by the spline on the toothholder; Jack shaft is bearing on the housing by roller bearing, and grade gear of each on the jack shaft is gone up the corresponding one by one engagement of each grade gear with second; Idler shaft directly is bearing on the housing, and idle pulley is arranged on the idler shaft; Take this to constitute the transmission of four 11 tooth secondarys and can realize the structure of six last gear combinations of falling, wherein each gear of speed changer all is the helical gear engagement driving.
As the further improvement of technological scheme, one on the described jack shaft, two-speed gear and jack shaft are made of one, and all the other each grade gears are installed on the jack shaft by hot jacket; Idle pulley is enclosed within on the idler shaft by the needle bearing sky, and both sides have holds the mill pad.
The utility model topology layout is reasonable, can realize that forward gears gear number is 6, and reverse gear gear number is 1, forward gears slowest ratio 7.617, reverse gear ratio 7.059; The speed changer forward gears is a synchronizer shift except that one grade entirely, one grade and reverse gear employing collar shift.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1, first 1 of the present utility model is fixed on the housing 3 by full roller cylindrical bearing 2, and the shelves ring on first 1 makes its axially locating with the stop ring on the bearing outer ring.Second 9 one end is bearing in by full type roller bearing in first 1 the endoporus, and the other end is bearing on the housing 3 by the full roller bearing 10 of outer astragal stop ring, and each shifting gear is enclosed within on second 9 by the needle bearing sky; Between the second gear, three fourth gear, five or six grades synchronizer shift mechanism is housed respectively, one grade, reverse gear are equipped with collar shift mechanism, and each gearshift mechanism is fixed on second 9 by the spline on the toothholder.Jack shaft 7 two ends are bearing on the housing 3 by roller bearing, with second 9 on the corresponding one by one engagement of each grade gear, the front end axial float.Idler shaft 5 directly is bearing on the housing 3, and idle pulley 6 is enclosed within on the idler shaft 5 by the needle bearing sky, with 7 one grades of gear engagement of jack shaft in, be meshed with reverse-gear on second 9.
Under the choosing of top cover assembly 14, shift lever effect, shift fork system in the last cap assembly 13 begins to move forward and backward, driving synchronizer shift mechanism between each grade or the tooth cover in the collar shift mechanism moves forward and backward, boring upper spline synchronously with a certain shelves combines, the free gear and the diaxon of a certain gear on first 1 or second 9 are combined into one, realize the power output of this gear.When the cover reach of reverse gear tooth engages with reversing toothholder upper spline, power through first 1 to reduction gear 4, successively via jack shaft 7, idle pulley 6, reverse-gear 11, the toothholder 12 of moveing backward, second spool 9, after bead 8 is exported to transmission shaft.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment did.
