Abstract
The utility model discloses a reverse gear device of a positive three-wheeled/four-wheeled motor vehicle and relates to the technical field of motor vehicles. In a shell, output spline shafts are supported by a bearing; the output spline shafts in the shell are connected with a combination gear that can slide axially; the output spline shafts at the two sides of the combination gear are respectively fixed and connected with a forward driven cone gear and a retrogressive driven cone gear; input driving cone gears that are respectively meshed with the forward driven cone gear and the retrogressive driven cone gear are arranged outside the forward driven cone gear and the retrogressive driven cone gear; a shifting fork is arranged outside the combination gear and is connected on a shift shaftby a shifting fork seat; the shift shaft is supported on the shell and is vertical to the output spline shafts axially; and one outer end of the shift shaft is fixedly connected with a gear shift pedal. The reverse gear device has the advantages of good safety, reliable gear shift, long service life, less abrasion and low noise.
Description
Technical field
The utility model relates to the motor vehicle technology field, relates in particular to a kind of positive three or the four-wheel motor cycle gear reversing device.
Background technology
At present, positive three, four-wheel motor cycle gear reversing device all is by two kinds of chain gear and shaft drive, chain gear will progressively become history, what replace is gear reversing device, and at present, the reverse gear on the market exists a lot of not enough, success ratio and reverse gear life-span to gear shift can not guarantee, the wearing and tearing of gear are big, and the noise of generation is also high, easily trip stop and phenomenon such as stuck in driving process.Stayed driving hidden danger to chaufeur largely.
The utility model content
The technical problems to be solved in the utility model provides that a kind of safety, gear shift are reliable, long service life, wearing and tearing are little, noise is little positive three, four-wheel motor cycle gear reversing device.
The utility model passes through the bearings output spline in housing, one end of described output spline stretches out in housing, connect the combination gear that can slide vertically on the output spline in housing, the advance driven cone gear and the driven cone gear that falls back of captive joint respectively on the output spline of knot body gear both sides is at the arranged outside and the driven cone gear and the driven cone gear ingear input initiative taper generating gear respectively that falls back of advancing of the advance driven cone gear and the driven cone gear that falls back; Arrange a shift fork in the outside of described combination gear, described shift fork is connected on the shift shaft by the shift fork seat, described shift shaft is supported on the described housing, and described shift shaft is axially vertical mutually with output spline, in an outer end captive joint shifting foot pedal of shift shaft.
Input initiative taper generating gear of the present utility model is connected on the power take-off shaft of driving engine, when the pilot control shifting foot pedal, by the afterburning shift fork of giving of shift fork seat, to stir combination gear and combine with the advance driven gear or the driven gear that falls back, the phenomenon of escape shelves can not appear.At this moment, in the time of operation stretcher front end, be D Drive.In the time of operation stretcher rear end, be backward gear.
The utility model is simple and reasonable for structure, convenient produces, assembling, the convenient use optimized the deficiency of existing reverse gearing device, has realized safety, reliable, long service life, the gear shift function that wearing and tearing are little, noise is little.
Produce for convenience, an end of shift fork seat described in the utility model can be fixedly connected on the shift shaft, and the other end is connected with shift fork.
In addition, in order to prevent oil leakage, between the utility model output spline and the housing oil sealing is set.
In order to have improved intensity, increase torque, guarantee that housing is not damaged, output spline described in the utility model also can be connected with housing by two groups of bearings in oil sealed the inner.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 bows to scheme drawing for Fig. 1's.
Fig. 3 is the connection diagram of shift shaft and shift fork seat and shift fork.
The specific embodiment
As shown in Figure 1, 2, 3, support output spline 2 by bearing 9,11,13 in housing 1, an end of output spline 2 stretches out in housing 1, between output spline 2 and housing 1 oil sealing 14 is set.
Connect the combination gear that can slide vertically 6 on the output spline 2 in housing 1, the advance driven cone gear 5 and the driven cone gear 3 that falls back of captive joint respectively on the output spline 2 in two outsides of knot body gear 6 can be distinguished ingear input initiative taper generating gear 4 at arranged outside and the advance driven cone gear 5 and the driven cone gear 3 that falls back of the advance driven cone gear 5 and the driven cone gear 3 that falls back.
On housing 1 by the axially vertical shift shaft 7 of bearings, in an outer end captive joint shifting foot pedal 10 of shift shaft 7 with output spline 2.Captive joint shift fork seat 12 on the shift shaft 7 in housing 1, the lower end of shift fork seat 12 connects shift fork 8, and this shift fork 8 is arranged on the outside of combination gear 6.
