Abstract
The utility model relates to an external forward and reverse gear shaft driving device for motor tricycles, which comprises a housing output shaft. The improvement of the utility model is that an input device is composed of a main driving bevel gear and a centripetal thrust bearing which is arranged on the bottom of one side of a housing; an output device is composed of an output shaft which penetrates through the housing, a forward bevel gear and a reverse bevel gear which are symmetrically arranged on the output shaft, and a centripetal thrust bearing which is arranged on a connecting part between the output shaft and the housing; a reversing device is composed of a reversing spline sleeve which is arranged between a pair of angle gears arranged on the output shaft, a shifting yoke arranged above the reversing spline sleeve, and a guiding shaft which is arranged on the housing and connected with the guiding shaft. The utility model has the advantages of small size, high drive precision, low cost, etc.
Description
The utility model relates to a kind of driving device of motor-tricycle, relates in particular to the positive reverse gear shaft driving device of a kind of motor-tricycle external.
At present, being seen motor-tricycle does not all have reverse gear transmission mostly on the market, this brings inconvenience for travelling of motor-tricycle, just seem more inconvenient when especially the loading of loading motor-tricycle is unloaded, also some motor-tricycle is equipped with reverse gear mechanism now, adopted dental clutch, because its scantling of structure is little, the number of teeth is few, in conjunction with separate all very difficult, for make its in conjunction with or separate and will make big gap easily, in operation process, impact big, noise greatly, very easily damage but cause.
The purpose of this utility model is to overcome defective and the deficiency that exists in the prior art, provides a kind of volume little, transmission accuracy rate height, and the positive reverse gear shaft transmission device of motor-tricycle external with low cost.
The purpose of this utility model is realized by following technical scheme:
The positive reverse gear shaft driving device of this motor-tricycle external, comprise housing 11, output shaft 20, its improvements are that it is that radial thrust bearing 5 by differential bevel wheel 22 and housing one side bottom constitutes input media, by output shaft 20 that passes housing and symmetrical forward and the reverse bevel-gear sett 6 that is installed on the output shaft 20,19 and be installed in the radial thrust bearing 2 of output shaft 20 and housing 11 connections, 7,10 constitute output unit, reversing arrangement is by being contained in bevel-gear sett 6 on the output shaft 20, commutation spline housing 3 between 19, mounted thereto shift fork 13 is formed with the shift fork 13 bonded assembly axis of guides 18 with being contained on the housing 11.
Described finishing bevel gear cuter 6,19 and final gear 22 are constant-mesh.
In the outside of housing 11 two ends radial thrust bearings 2,7,10, bearing gland 1,8 is housed respectively.
The key number of teeth of described commutation spline housing 3 is at least 6.
The described axis of guide 18 upper ends are provided with 3 detents, are provided with ball 14, spring 17, holding screw 16 in the above successively, regulate bolt 15.
Compare with conventional art, it is little to the utlity model has volume, the transmission accuracy height, and advantage such as with low cost is the comparatively ideal positive reverse gear shaft driving device of present motor-tricycle.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the main cutaway view of the positive reverse gear shaft driving device of this motor-tricycle external;
See also shown in Figure 1, the radial thrust bearing 5 of the differential bevel wheel that is connected with engine output shaft 23 22 it and housing 11 1 side bottoms has constituted input media, forms output unit by the output shaft 20 that passes housing 11, radial thrust bearing 2,7,10, bearing gland 1,8 and finishing bevel gear cuter 6,19.The axle and housing 11 connections of output shaft device are equipped with radial thrust bearing 2,7,10 respectively, and bearing gland 1,8 is housed respectively.Symmetry is equipped with forward and reverse a pair of gear 6,19 on the output shaft, to guarantee its running accurately on output shaft.This bevel-gear sett and final gear are constant-mesh, and its back lash is adjusted by the bearings at both ends lid.Reversing arrangement is formed with the commutation shift fork bonded assembly axis of guide 18 by being contained in the commutation spline housing between the bevel-gear sett on the output shaft 3 shift forks 13 mounted thereto and being contained on the housing.Its external diameter of commutation hub splines is a male splines, internal diameter is a female splines, its key tooth number is at least 6, operating mechanism is a handle, it links to each other with the axis of guide 18, and positive reverse gear position is to finish by the displacement of the axis of guide 18, and there are three detents the upper end of the axis of guide 18, be provided with ball 14, spring 17, holding screw 16 above and regulate bolt 15, its handle can be installed in is convenient to any position of operating on the vehicle frame.
