Abstract
The present invention relates to transfer case for belt driving wheel type tractor. Inside the transfer case, there are installed power input shaft and driving shaft with perpendicular axes, driving bevel gear installed to the end of the power input shaft, driven bevel gear installed on to the driving shaft and normally meshed to the driving bevel gear, and clutch set between the driven bevel gear and the driving shaft. The transfer case may be installed outside the gear box of the belt driving wheel type tractor, and the power input shaft may be connected to the V-shaft of the gear box, so as to utilize available gear box resource to realize the four-wheel driving of belt driving tractor in least investment.
Description
Technical field
The present invention relates to a kind of transfer case for belt driving wheel type tractor.
Technical background
All be provided with auxiliary gear box in the automobile of four wheel drive and the change speed gear box of trac., its effect is to engage the power input in needs, realizes f-w-d.The bel-drivenn trac., owing in the change speed gear box auxiliary gear box is not set, can not realize f-w-d, and in production practice, because bel-drivenn trac. purposes is extensive, often on muddy and rugged road, walk, users press for a kind of belt-driving trac. of four wheel drive, and consider from the angle of production manufacturer, should satisfy user's needs, utilize existing change speed gear box resource again as far as possible, to reduce design and production cost.
Summary of the invention
The purpose of this invention is to provide a kind of transfer case for belt driving wheel type tractor, can utilize the change speed gear box of the existing wheeled trac. of belt-driving, realize f-w-d.
For achieving the above object, the present invention adopts following technical scheme:
Transfer case for belt driving wheel type tractor of the present invention comprises casing, power input shaft and transmission shaft are installed in casing, the axis of power input shaft and transmission shaft is orthogonal, the end fixed installation driving bevel gear of power input shaft, driving bevel gear and the passive bevel gear constant-mesh that is sleeved on the transmission shaft are provided with arrangement of clutch between passive bevel gear and the transmission shaft.
Described arrangement of clutch comprise by keyway be connected on the transmission shaft by dynamic interlocking teeth, with by dynamic interlocking teeth bonded assembly shift fork, be connected control stalk axle on the shift fork by camshaft, connect control stalk on the control stalk axle, have on the passive bevel gear with by the corresponding active jaw of dynamic interlocking teeth.
Be set with terminal pad on the exterior power input shaft of casing, terminal pad is captiveed joint with casing.
After adopting technique scheme, this auxiliary gear box can be fixedly mounted on the outside of the change speed gear box of ordinary straps transmission wheel type trac., and power input shaft is connected with change speed gear box V axle, so just can utilize existing change speed gear box resource, reach the purpose of belt-driving trac. four wheel drive with the input of minimum.
Description of drawings
Accompanying drawing is the cutaway view of one embodiment of the present of invention.
The specific embodiment
As shown in drawings, transfer case for belt driving wheel type tractor of the present invention comprises casing 1, and 1 is provided with the transmission shaft 3 that runs through casing in casing, transmission shaft 3 by bearing installation on casing 1.Other have the power input shaft 2 vertical with transmission shaft 3 by bearing installation on casing 1; The end fixed installation driving bevel gear 4 of power input shaft 2 is set with passive bevel gear on the transmission shaft 3, driving bevel gear 4 and passive bevel gear 5 constant-meshes are provided with arrangement of clutch between passive bevel gear 5 and the transmission shaft.Described arrangement of clutch comprise by keyway be connected on the transmission shaft 3 by dynamic interlocking teeth 6, with by dynamic interlocking teeth 6 bonded assembly shift forks 7, be connected control stalk axle 8 on the shift fork 7 by camshaft, centre by dynamic interlocking teeth 6 has fork slot, has active jaw with passive bevel gear 5 cooresponding sides.Have on the passive bevel gear 5 with by dynamic interlocking teeth 6 corresponding active jaws 9, connect control stalk on the control stalk axle 8.For the ease of casing 1 is fixed on the change speed gear box, on casing 1 exterior power input shaft 2, be set with terminal pad 10, terminal pad 10 is captiveed joint with casing 1.
During use, casing 1 is fixed on the position of gearbox body one side V axle, change speed gear box V axle and power input shaft 2 is coupled together with falcon groove connection mode by terminal pad 10.During engine operation, drive the rotation of V axle, power input shaft 2 rotations are arrived passive bevel gear 5 by bevel gear adjutant transmission of power, because passive bevel gear 5 is that movable set is on transmission shaft 3, though this moment, passive bevel gear 5 rotations or not on the transmission shaft 3; When handling control stalk and make the camshaft rotation, shift fork 7 stir by dynamic interlocking teeth 6 make its with passive bevel gear 5 on active jaw 9 interlocks, at this moment, passive bevel gear 5 drives and is rotated by dynamic interlocking teeth 6, rotates and driven transmission shaft 3 by dynamic interlocking teeth 6.If again by drivings device such as universal-joints with the transmission of power of transmission shaft 3 rotation to propons, and finally drive the front-wheel rotation, can realize the f-w-d of trac..
Because transmission shaft and devices such as universal-joint, propons are the known technologies of comparative maturity, do not need further explanation at this.
Certainly, the arrangement of clutch between passive bevel gear 5 and the transmission shaft 3 can also have multiple.For example, passive bevel gear 5 can also be installed on the transmission shaft 3 by spline, shift fork is directly dialled passive bevel gear, and passive bevel gear directly drives transmission shaft rotation, as long as stir passive bevel gear during separation it is separated with driving bevel gear 4.
