Abstract
Provided is a spindle assembly for a double-intermediate-shaft transmission. The technical scheme of the spindle assembly is that axial positioning of a gear on a spindle is achieved through eight spindle adjusting gaskets, radial positioning of the gear on the spindle is achieved through mutual mesh between the spindle gear and a countershaft gear, and the spindle assembly is simple in structure, strong in bearing capacity, short in axial length and low in noise. For the double-intermediate-shaft transmission, gears at all gear positions of the spindle float on the spindle in the radial direction, and axes of the spindle and a countershaft are located in the same plane, so that radial force generated by meshing of the gears offsets mutually, namely the spindle only transmits torque and resultant force of the spindle stressed by the radial force is zero. The spindle assembly is simple in positioning structure, strong in bearing capacity and high in durability, and prolongs service life of the double-intermediate-shaft transmission under the premise of not increasing cost.
Description
Technical field
The present invention is a kind of for being used for the main shaft assembly of twin countershaft transmission.
Background technique
Two jack shaft structure speed changers have advantages such as compact structure, gearshift power is little, the life-span is long, are widely used in road vehicle.Present employed main shaft assembly position structure is the axially locating that realizes main shaft assembly through bearing, and part is more, and price is high, and assembling is complicated.
Summary of the invention
The present invention is directed to the deficiency of existing technology, and a kind of main shaft position structure is provided, it is installed simply, reject rate is low; Long service life; Adopt the twin countershaft transmission of this position structure, its reliable operation, gearshift time are fast, gearshift power is little etc., are specially adapted to road vehicle.
The present invention realizes through following technical measures: a kind of main shaft assembly that is used for twin countershaft transmission; Comprise main shaft, be installed in the plurality of gears on the main shaft; Said main shaft is provided with the long keyway that adapts with the main shaft size; In the said long keyway hex key is installed, said hex key is through the elastic cylindrical pin axially locating, and said gear is installed on the main shaft through hex key; The both sides of said gear are equipped with the main shaft adjustment pad that is connected with hex key, and said main shaft adjustment pad carries out axially locating to gear.
Concrete characteristics of the present invention also have, and said gear is equipped with main shaft four retaining gears, main shaft three retaining gears, main shaft second gear, main shaft first gear and main shaft reverse gear successively through main shaft adjustment pad and hex key axially locating on the main shaft; On the main shaft between said main shaft four retaining gears and the main shaft three retaining gears main shaft adjustment pad is installed, on the said main shaft and the arranged outside that is positioned at main shaft four retaining gears and main shaft three retaining gears have main shaft to adjust pad; Main shaft adjustment pad is installed on the main shaft between said main shaft second gear and the main shaft first gear, on the said main shaft and the arranged outside that is positioned at main shaft second gear and main shaft first gear have main shaft to adjust pad; On the said main shaft and the both sides that are positioned at the main shaft reverse gear are provided with main shaft adjustment pad.
Beneficial effect of the present invention is: guarantee to be used for the axially locating of the main shaft assembly of twin countershaft transmission by cooperatively interacting between main shaft adjustment pad, main shaft, hex key and each gear of main shaft, orientation type is simple and direct.
The axially locating of twin countershaft transmission mainshaft gear is to realize that by eight main shaft adjustment pads realize its radial location through being meshing with each other of mainshaft gear and counter shaft gear, it is simple in structure, bearing capacity is strong, axial length is short, noise is low; For twin countershaft transmission, main shaft respectively keeps off gear radial floating on main shaft, and the axis of major and minor axle is in the same plane, and the radial force that gear engagement produced is cancelled out each other, i.e. a main shaft transmitting torque, and making a concerted effort of force in radial is zero.
In sum: this position structure is simple, bearing capacity is strong, durability is high, under the prerequisite that does not increase cost, has improved the life-span of twin countershaft transmission.
Description of drawings
Fig. 1 is for being used for the structural representation of the main shaft assembly of twin countershaft transmission in the specific embodiment of the invention.
Among the figure, 1, the main shaft reverse gear, 2, the main shaft first gear, 3, the main shaft second gear, 4, main shaft three retaining gears, 5, main shaft four retaining gears, 6, hex key, 7, main shaft, 8, elastic cylindrical pin, 9, main shaft adjustment pad.
Embodiment
For clearly demonstrating the technical characterstic of this programme, through an embodiment, this programme is set forth below.
Shown in accompanying drawing; A kind of main shaft assembly that is used for twin countershaft transmission; Comprise main shaft, be installed in plurality of gears on the main shaft etc., said main shaft is provided with the long keyway that adapts with the main shaft size, and hex key 6 is installed in the said long keyway; Said hex key 6 is through elastic cylindrical pin 8 axially locating; Said gear is installed on the main shaft through hex key 6, and the both sides of said gear are equipped with the main shaft adjustment pad 9 that is connected with hex key 6, and 9 pairs of gears of said main shaft adjustment pad carry out axially locating.Wherein, Gear, hex key, main shaft, elastic cylindrical pin and main shaft adjustment pad cooperatively interact be connected in aggregates; Reach the purpose of axially locating through the cooperation of main shaft adjustment pad, each gear of main shaft, hex key and main shaft, it is simple in structure, bearing capacity is strong, axial length is short, noise is low.
Wherein, through main shaft adjustment pad 9 and hex key 6 axially locating main shaft four retaining gears 5, main shaft three retaining gears 4, main shaft second gear 3, main shaft first gear 2 and main shaft reverse gear 1 are installed successively on the main shaft; On the main shaft between said main shaft four retaining gears 5 and the main shaft three retaining gears 4 main shaft adjustment pad 9 is installed, on the said main shaft and the arranged outside that is positioned at main shaft four retaining gears 5 and main shaft three retaining gears 4 main shaft adjustment pad 9 is arranged; Main shaft adjustment pad 9 is installed on the main shaft between said main shaft second gear 3 and the main shaft first gear 2, on the said main shaft and the arranged outside that is positioned at main shaft second gear 3 and main shaft first gear 2 main shaft adjustment pad 9 is arranged; On the said main shaft and the both sides that are positioned at main shaft reverse gear 1 are provided with main shaft adjustment pad 9.This shows the axially locating that realizes five gears on the main shaft through eight main shaft adjustment pads.
Gearshift power is transmitted through mainshaft gear and main shaft adjustment pad, because main shaft adjustment pad and mainshaft gear all are installed on the main shaft, power is delivered on the main shaft the most at last, does not have relative movement between gear and main shaft adjustment pad, has realized axially locating.
Realized by being meshing with each other between major and minor shaftgear that balanced radial force reaches and cancelled out each other that making a concerted effort of main shaft force in radial is zero, a transmitting torque is realized radial location.
The present invention can pass through or adopt existing techniques in realizing without the technical characteristics of describing; Repeat no more at this; Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited in above-mentioned giving an example; Variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also should belong to protection scope of the present invention.
