Embodiment
Further describe below in conjunction with accompanying drawing and embodiment's specific embodiments of the invention, following examples only are used for technological scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
As shown in Figure 1, the technological scheme of practical implementation of the present invention is that a kind of double cone hydraulic pressure adds the compact form towing gear, comprises external friction wheel 1, interior friction wheel 7, one group of above speed regulating mechanism and hydraulic pressure hold-down mechanism;
Wherein, every group of speed regulating mechanism is made up of sliding support 9, back shaft 6, female cone roller 8, outer cone roller 2, speed change adjustable lever 4 and adjusting oil cylinder 5; At the groove of the bottom surface of female cone roller 8 processing, be processed with the boss that is complementary with female cone roller 8 bottom recesses in the bottom surface of outer cone roller 2 along axial direction; Process round platform at female cone roller 8 end faces and outer cone roller 2 end faces along axial direction;
The hydraulic pressure hold-down mechanism is made up of oil pocket end cap 3 and hydraulic fluid chamber 11; The bottom surface of oil pocket end cap 3 is processed with the groove that is complementary with female cone roller 8 end faces and outer cone roller 2 end faces;
Its annexation is: female cone roller 8 grooves and outer cone roller 2 boss coupling are installed; The groove of female cone roller 8 cooperates with the boss free-sliding spline of outer cone roller 2; The round platform of the round platform of female cone roller 8 end faces, outer cone roller 2 end faces is installed with oil pocket end cap 3 grooves coupling respectively, forms hydraulic fluid chamber 11 at female cone roller 8 round platforms and oil pocket end cap 3 grooves, outer cone roller 2 round platforms and oil pocket end cap 3 grooves; Medial axis direction at female cone roller 8 and outer cone roller 2 is installed back shaft 6, and the oil pocket end cap 3 that two ends are passed at back shaft 6 two ends respectively is installed on sliding support 9 and the speed change adjustable lever 4, and speed change adjustable lever 4 the other ends link to each other with adjusting oil cylinder 5;
When hydraulic fluid chamber 11 was pressurizeed, female cone roller 8 was slidingly matched with rotating shaft respectively with outer cone roller 2 and moves inward along the medial axis, and friction wheel 7 contacts with the conical surface of female cone roller 8 in making, external friction is taken turns 1 and contacted with the conical surface of outer cone roller 2.
In said back shaft 6 and female cone roller 8 and outer cone roller 2, bearing is installed.
Friction wheel 7 is as power intake in said, and said external friction wheel 1 is a clutch end.
Said external friction wheel 1 is as power intake, and said interior friction wheel 7 is a clutch end.
The transmission of power of the stepless speed changes devices of this kind structure type has been utilized the cutting performance and the load-carrying properties of traction under the high pressure; Be compared to and rely on directly other friction type stepless speed changes devicess of contact of metal surface; This device has been avoided the direct contact of friction surface; Improve transmission capacity and working life, and can be applicable to the bigger occasion of power.
From structural type; The a pair of speed cone roller of this stepless speed changes devices has adopted opposed form first; The structure of forming similar spindle; The radius of clean-up of friction wheel 7 and external friction wheel 1 in can regulating like this can realize subtracting from the deceleration increment to speedup square or reciprocal continuous variation in the whole process that speed regulating mechanism is regulated.In addition, the structural type of spindle can be so that hydraulic pressure steps up the end that device is arranged in spindle, and the layout of oil duct and oil pocket is easy relatively.
Because the active force of 7 interior friction wheels, 1 pair of two circular cone roller of external friction wheel is not point-blank, because the effect of moment of flexure certainly will make two circular cone roller link positions become weak link.Adding the higher back shaft 6 of intensity can make it bear the effect of most of moment of flexure.The another one effect of back shaft 6 is to connect adjustable lever 4 and sliding support 9, supports female cone roller 8 and outer cone roller 2, when oil hydraulic cylinder moves, guarantees whole the moving axially of speed regulating mechanism.
When taking two groups of speed regulating mechanisms; The female cone roller 8 of speed regulating mechanism and interior friction wheel 7 are for being symmetrical set; Outer cone roller 2 takes turns 1 for being symmetrical set with external friction, and when hydraulic fluid chamber 11 was pressurizeed, every group female cone roller 8 was slidingly matched with rotating shaft respectively with outer cone roller 2 and moves inward along the medial axis; Friction wheel 7 contacts with the conical surface of female cone roller 8 in making, external friction is taken turns 1 and contacted with the conical surface of outer cone roller 2.
When taking more than three groups speed regulating mechanism; The female cone roller 8 of speed regulating mechanism and interior friction wheel 7 are for being uniformly distributed with setting; Outer cone roller 2 takes turns 1 for being uniformly distributed with setting with external friction, and when hydraulic fluid chamber 11 was pressurizeed, every group female cone roller 8 was slidingly matched with rotating shaft respectively with outer cone roller 2 and moves inward along the medial axis; Friction wheel 7 contacts with the conical surface of female cone roller 8 in making, external friction is taken turns 1 and contacted with the conical surface of outer cone roller 2.
The above only is a preferential mode of execution of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
