Abstract
The invention discloses a transfer case of an automobile and relates to a transmission structure of an automobile. The invention is characterized in that an output shaft is added to a transmission case, the added output shaft is positioned below an input shaft and is arranged in the same vertical plane with the axial lead of the input shaft, and the two axial leads of the added output shaft and the original output shaft are positioned in the same horizontal plane; the added output shaft is fixedly sheathed with an output gear, a back gear on a middle shaft is engaged with the added output shaft; the back end of the added output shaft extends from the back end part of a back wall body and is fixedly provided with a ring flange; and the back end of the original output shaft is stopped at the back wall body of the case body, and the front end of the output shaft extends from the back end part of the front wall body and is provided with a ring flange. The invention has the advantages that the transfer case is provided with a front output shaft and a back output shaft which are independently arranged, and the axial leads of the two output shafts respectively correspond to the axial leads of the input shafts of a front reducer assembly and a back reducer assembly, thereby enabling the front transmission shaft and the back transmission shaft to realize the transmission without deflection or with less deflection and simultaneously improving the transmission efficiency and the energy utilization.
Description
Technical field:
The present invention relates to the vehicle transmission structure, be specially adapted to the part-time case structure.
Background technology:
Rear Double drives the transfer case of automobile structure by the shifting fork device of the gearshift inner gear of fit on casing, input shaft, the input shaft, the outer garden of gearshift inner gear fit, the tween drive shaft that gear is meshed with front and back gear on the input shaft before and after it, the output gear that is meshed with the tween drive shaft backgear, and the bearing fixedly installed on the output shaft, each root axle of fit of output gear at present, stretch out the fixing front and back output flange in output shaft two ends on casing both sides and form, output shaft and input shaft two axial lines are at the about 200mm of horizontal surface direction offset distance.
The vehicle transmission mode is that engine spindle drives the rotation of part-time case input shaft, the part-time case output shaft only is a single shaft, the flange of rear axle propeller shaft end rotated before the front and back end flange of single shaft drove and is fixed on, rotate thereby drive forward and backward transmission shaft, the other end of forward and backward transmission shaft is connected with the input shaft of forward and backward deceleration assembly again.Thereby make forward and backward bridge realize two the driving.Because engine installation generally is positioned on the car chassis line of centers at its engine output shaft axial line on the chassis, that is to say that the part-time case input shaft also is positioned on the vehicle centerline, rear axle speed-reducing assembly input shaft generally also is on the center chassis line, and front axle deceleration assembly input shaft axial line generally is positioned at avris, with rear axle speed-reducing assembly input shaft axial line level be about 200mm to offset distance.Thereby rear axle propeller shaft is tilting from the horizontal surface direction, and its tilting state underdrive efficient reduces energy dissipation simultaneously.
Summary of the invention:
The objective of the invention is to overcome above-mentioned defective, a kind of transfer case of automobile is provided.
The solution of the present invention is: the tween drive shaft that is meshed with front and back gear on the input shaft by the shifting fork device of the gearshift inner gear of fit on casing, input shaft, the input shaft, the outer garden of gearshift inner gear fit, front and back gear, the output gear that is meshed with the tween drive shaft backgear, and the bearing fixedly installed on the output shaft, each root axle of fit of output gear form, output shaft and input shaft two axial lines are at the about 200mm of horizontal surface direction offset distance.On transmission gearbox, set up an output shaft, added output shaft is combined on the casing by two bearing carrier rings, added output shaft is positioned at the input shaft below and is in same heavy vertical direction plane with the input shaft axial line, and added output shaft and former output shaft two axial lines are on the same horizontal surface; A fixed cover unification output gear on the added output shaft, the backgear on the tween drive shaft also is meshed with the added output shaft gear simultaneously; Added output shaft front end stop bit is fixed with bearing cap shim in preceding body of wall, the external wall correspondence position of front wall, and its rear end is stretched out the back wall rearward end and is fixed with flange; Former output shaft rear end stop bit is fixed with bearing cap shim in casing back wall, back wall outer wall correspondence position, and the body of wall rearward end was fixed with flange before its front end stretched out.
The invention has the advantages that: two independent output shafts before and after auxiliary gear box is arranged to, make two output shaft axial lines correspond respectively to forward and backward deceleration assembly input shaft axial line, thereby make forward and backward transmission shaft realization horizontal direction not have drift angle or the transmission of little drift angle, driving efficiency, energy utilization rate improve simultaneously.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is gabarit master's diagrammatic sketch of the present invention.
The specific embodiment:
Structure of the present invention by casing (1), input shaft (2), input shaft (2) go up the tween drive shaft (3) that the shifting fork device, front and back gear of gearshift inner gear, the outer garden of the gearshift inner gear fit of fit be meshed with front and back gear on the input shaft (2), the output gear that is meshed with tween drive shaft (3) backgear, and the bearing fixedly installed on the output shaft, each root axle of fit of output gear form, output shaft and input shaft (2) two axial lines are at the about 200mm of horizontal surface direction offset distance.It is characterized in that: on transmission gearbox, set up an output shaft, added output shaft (5) is combined on the casing (1) by two bearing carrier rings, added output shaft (5) is positioned at input shaft (2) below and is in same heavy vertical direction plane with input shaft (2) axial line, and added output shaft (5) is on the same horizontal surface with former output shaft (4) two axial lines; Added output shaft (5) goes up a fixed cover unification output gear, and the backgear on the tween drive shaft (3) also is meshed with added output shaft (5) gear simultaneously; Added output shaft (5) front end stop bit is fixed with bearing cap shim in preceding body of wall, the external wall correspondence position of front wall, and its rear end is stretched out the back wall rearward end and is fixed with flange; Former output shaft (4) rear end stop bit is fixed with bearing cap shim in casing (1) back wall, back wall outer wall correspondence position, and the body of wall rearward end was fixed with flange before its front end stretched out.
Two independent output shafts before and after being provided with, be connected with the front and back transmission shaft by the flange on two output shafts respectively, since two output shaft axial lines respectively on level corresponding to the axial line level of forward and backward deceleration assembly input shaft (2) to the position, so the level that realizes basically is to the transmission of no drift angle.As for the requirement of automobile auxiliary gear box setting height(from bottom) dependency rule, the axial line direction of heavily hanging down still keeps certain little spacing to make the forward and backward transmission shaft direction of heavily hanging down still keep certain low-angle deviation, but level to correction greatly improved driving efficiency.
