Abstract
The utility model relates to the arrangement and installation of the vehicle transmission device, which is a friction ball differential mechanism used for vehicle transmission to use. Friction discs 6 and 9 are matched between the shaft sleeves 2 and 11, and the friction discs 6 and 9 are transmitted to rotate and move relying on a rolling element 7 which is embedded in a part 8; the supporting rod is sheathed with a pressing spring 5 and a pre-fastening component 4. The utility model solves the defect that the manufacturing cost of the existing equipment is relatively high, and the transmission semi-shaft is easy to screw and break at overloading. The utility model has the advantages of convenient manufacture and capability of regulating the transmission force, and the transmission part can be protected through the relative slide of the steel ball and the extrusion disc at instantaneous overload operation.
Description
The utility model belongs to the layout and the installation of vehicle transmission gear, is to be used for the friction ball differential mechanism that system of vehicle transmission and machine tool use.
The differential mechanism that existing vehicle uses belongs to satellite differential mostly, and its manufacturing process complexity and precision prescribed height are for transmission part unprotect effect under event of overload; Notification number is that the steel ball differential clutch of announcing among the CN86104028A utilizes the interaction of steel ball, the conical surface and curvilinerar figure tooth to finish the function of differential mechanism and clutch, but it is big to exist steel ball degree of wear in the cavity that the conical surface is formed, technical disadvantages such as gearshift performance difference.
The purpose of this utility model is to provide a kind of and adjusts transmission power and reach friction ball differential mechanism that transmission part is shielded to solve the deficiency of prior art by slide relative when instantaneous overburdening.
Overall structure of the present utility model is:
The friction ball differential mechanism relies on the friction conveying rotary motion between the rotatable member; It is characterized in that between axle sleeve 2,11, having connected friction disk 6,9, friction disk 6,9 inboards are furnished with part 8, the rolling member 7 that is embedded on the part 8 cooperates with the rolling of friction disk 6,9 inner edges, support to be provided with between axostylus axostyle 1 middle part and axle sleeve 11 and the friction disk 9 and slide or rolling member 10, support suit stage clip 5 and pretension member 4 on the axostylus axostyle 10.
Other technologies feature of the present utility model also has:
The pretension member 4 that supports the assembling of axostylus axostyle 1 left side is a nut, and bayonet lock 3 is set on the pretension member 4, and stage clip 5 is arranged between pretension member 4 and the friction disk 6.
The feature of part 8 of the present utility model and slip or axle sleeve 2,11 is:
Part 8 outer rims and axle sleeve 2,11 external port are a kind of in the adpting flange of gear, sprocket wheel, belt pulley or other kinds that connect power, slide or rolling member 10 is a bearing.
The feature of rolling member 7 is:
Rolling member 7 is a rigid ball.
Accompanying drawing of the present utility model has:
Fig. 1 is a structural representation of the present utility model.
In conjunction with the accompanying drawings embodiment of the present utility model is described as follows:
Working principle of the present utility model is:
1, when using as the motor vehicle differential mechanism, when power transmission is given part 8, part 8 drives friction disk 6,9 by steel ball 7 and rotates, friction disk 6,9 passes to the jackshaft driving wheel by axle sleeve 2,11 respectively and rotates, thereby the pressure that pre-load nut is adjusted 6,9 pairs of balls of friction disk by stage clip 5 reaches the size of adjusting transmission power.
2, part 8 is fixing by axle sleeve 2, the 11 transmission rotating force direction that then passive side will be opposite with transmission side rotations.
3, as axle sleeve 2,11 any one party are fixed, transmit rotating force by part 8, then unfixing side will be with the speed rotation of part 8 rotating speed twices.
Technological progress of the present utility model is:
This differential mechanism is made simple, does not need special equipment, can adjust pre-load nut according to different needs, and the relative sliding that produces by steel ball and frictional disk when instantaneous excess load plays a protective role to drive disk assembly.
