Description
(1) technical field
The utility model relates to a kind of driving transfer device, particularly a kind of device that is used for the conversion of four-wheel motor cycle transmission input end two/4 wheel driven.
(2) background technology
At present, the driving switching mechanism of four-wheel motor cycle is generally two kinds of forms: the one, and the transmission mouth conversion of mechanical control, but it exists front drive gear case and steering unit is integral type, maintenance difficult, and transfer torque is big on the driven gear, the requirement of strength height, scantling of structure is big, and material expends many problems; The one, motoroperated transmission input end conversion, but it exists manipulation process longer, indicator lamp confirms to put in place the position must be visual, handles not intuitively, and reliability is not so good as the high problem of physical construction.
(3) summary of the invention
The purpose of this utility model provides a kind of four-wheel motor cycle transmission input end and drives transfer device.It is the mechanical control mode, and scantling of structure is little, and transfer torque is little, and manipulation process is short, handle and put sense in place accurately, and the reliability height, easy to maintenance.
For reaching above-mentioned purpose, the utility model overlaps upper spring with an end of camshaft, and is connected with casing, and the cam that has cam path is installed at the middle part, and the other end passes case lid and is connected with transition arm.Cam is provided with two knock holees, and steel ball is fixed on by sliding sleeve, spring, plug screw in the groove of upper end of casing, and contacts with a knock hole on the cam.Finger one end inserts in the cam path of cam, and the other end is connected with slide block.Shift fork is connected with slide block, and its jaw is connected with spline housing.Above-mentioned driving switching mechanism is located at the transmission input end, and the castellated shaft that spline housing and two drives is for often to cooperate, and with the castellated shaft of 4 wheel driven be same axle center.
Owing to adopted said structure, shift fork moves as axial location with cam rotation, and stirs the spline housing connection or throw off the 4 wheel driven castellated shaft, realizes the conversion of four-wheeled two/4 wheel driven.The utlity model has simple in structure, easy to operate, the characteristics that tooling cost is low.
The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a structure diagram of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Fig. 3 is a kind of embodiment of the present utility model.
(5) specific embodiment
Referring to Fig. 1, Fig. 2, an end of camshaft 3 overlaps upper spring 8, and is connected with casing 1.The cam 7 that arc surface has cam path 19 is installed at its middle part, adopts the mode of pin joint, does radial location with pin, and cam 7 can be endwisely slipped on camshaft 3, also can adopt singly-bound or spline ways of connecting.Its other end passes case lid 5 and oil sealing 2 is connected with transition arm 4 splines.Case lid 5 seals with packing seal 6 with casing 1 junction.Cam 7 is provided with two knock holees, and the position of two knock holees is corresponding to the initial sum final position of cam 7 rotations.Steel ball 12 is fixed in the casing 1 upper end groove by sliding sleeve 13, spring 14, plug screw 10, and contacts with a knock hole on the cam 7.Plug screw 10 seals with tightening seal washer 9 with casing 1 junction.Finger 17 1 ends insert in the cam path 19 of cam 7, and the other end inserts in the slide block 16, perhaps is threaded.Shift fork 15 and slide block 16 are by pin 18 pin joints or be threaded, and its jaw is stuck in the draw-in groove on spline housing 11 circumference.Referring to Fig. 3, above-mentioned driving switching mechanism is located at the transmission input end, and the castellated shaft 21 that spline housing 11 and two drives is for often to cooperate, and with the castellated shaft 20 of 4 wheel driven be same axle center, and parallel with camshaft 3.
Referring to Fig. 3, four-wheel motor cycle is in two when driving work, transfers 4 wheel driven work to as need, and manipulation transforms arm 4 rotates camshaft 3, and camshaft 3 drives cams 7 and rotates.Along with the rotation of cam 7, force the finger 17 that inserts cam path 19 along the moving axially of cam 7, and by with finger 17 bonded assembly shift forks 15, stir and often be engaged in two spline housings 11 that drive on the castellated shaft 21 and on two castellated shafts that drive 21, move.After control action was finished, spline housing 11 temporarily can not connect two castellated shafts 21,20 of two/4 wheel driven smoothly, still was in disengaged condition with the spline of 4 wheel driven castellated shaft 20.At this moment, the mobile spring 8 that compressed because of cam 7, when treating that spline housing 11 is aimed at the spline of 4 wheel driven castellated shaft 20, the elastic force of spring 8 makes cam 7 endwisely slip along camshaft 3, and stirring spline housing 11 by shift fork 15 is connected with 4 wheel driven castellated shaft 20, thereby two castellated shafts that drive 21 are connected as one by spline housing 11 with 4 wheel driven castellated shaft 20, finish the transmitting and converting of two/four-driving-force.Simultaneously, with the rotation of cam 7, steel ball 12 skids off from the shrinkage pool of location, and the deformation force of sliding sleeve 13 medi-springs 14 is oppressed down up, searches out predetermined position location and finishes the location, and makes two/4 wheel driven drive state keep stable under obstacle of vibration.Otherwise motor bike such as need transfer two to from 4 wheel driven and drive, then manipulation transforms arm 4 backwards rotation, and drive camshaft 3, cam 7 backwards rotation.Along with the rotation of cam 7, force the finger 17 that inserts cam path 19 along the moving axially of cam 7, and by with finger 17 bonded assembly shift forks 15, stir the castellated shaft 20 that spline housing 11 breaks away from 4 wheel drivens, only be connected with two castellated shafts that drive 21, finish two and turn and change.Simultaneously, with the backwards rotation of cam 7, steel ball 12 skids off the shrinkage pool from the location, and up sliding sleeve 13 medi-springs 14 the deformation force compressing down, search out former position location and finish the location, and make two to drive drive state and under obstacle of vibration, keeps stablizing.
