Abstract
The present invention relates to the clutch technology of a stepless speed changer. A forward gear clutch of the provided stepless speed changer is arranged in a box body of the stepless speed changer and adopts a structure of a wet type friction clutch with hydraulic control; the input part of the forward gear clutch is linked with an output shaft of an engine, and the input part directly accepts the power of the output shaft of the engine and transfers the power to a driving cone disk shaft. In the stepless speed changer provided by the present invention, the forward gear clutch is directly connected with the output shaft of the engine, the forward gear clutch finishes the whole process from separation to complete combination through hydraulic control, namely that the operating oil pressure of the clutch is controlled by a microprocessor so that the pressing force of the clutch is in a controlled range and the combination and the separation of the clutch can be easier, and consequently, the clutch can replace a main clutch, and the speed change of vehicles is convenient and easy to be controlled. Meanwhile, the investment and the cost for production are reduced.
Description
Technical field:
The invention belongs to the Clutch Technology of stepless speed variator, mainly propose a kind of forward gear clutch of stepless speed variator.
Background technique:
Speed changer can be divided into three kinds because of the difference of gear changing mode: armstrong's patent formula shift transmission, electric liquid jointly control shift transmission (claiming self-shifting gear box again), and electric liquid jointly controls infinitely variable transmission (stepless speed variator of essential meaning).Motor field current is a large amount of, and what use is preceding two kinds of speed changers, and electric liquid jointly controls infinitely variable transmission just to be used in recent years and necessarily developed.Jointly control in the infinitely variable transmission at electric liquid, motor output is connected with gearbox by main clutch control back, and the structural type of main clutch has: magnetic clutch, fluid torque converter, dry type main clutch; Wherein, magnetic clutch has in conjunction with separating simple and reliable advantage, but can not smooth-going combination when magnetic makes moist caking with separate, and bigger variation can appear in the using effect of passing clutch in time, even inefficacy; The fluid torque converter structure has the best effects of flexible combination, but power loss is bigger, and complex structure and manufacture cost are higher; Dry clutch though present most of Motor Vehicle uses this kind structure, has the trend that is eliminated gradually because the separating and combining effect of this kind structure is relatively poor.Electricity liquid jointly controls and is provided with forward clutch and reverse clutch in the infinitely variable transmission, and forward gear clutch is connected with the output of main clutch; Finish the variation function of output shaft of gear-box sense of rotation by forward clutch and reverse gear brake.
Summary of the invention:
The forward gear clutch that the purpose of this invention is to provide a kind of stepless speed variator, by the improvement that its structure is provided with, make its repertoire that can realize the stepless speed variator main clutch simultaneously, make convenient and smooth and easy that the speed Control of vehicle becomes, reduce cost of production simultaneously.
The present invention finishes the technological scheme that its invention task takes: forward gear clutch is arranged in the casing of stepless speed variator, and forward gear clutch adopts the wet friction clutch structure of hydraulic control; The input part of forward gear clutch and engine output shaft interlock, it is directly accepted engine output shaft power and passes to initiative taper dish axle.
The stepless speed variator that the present invention proposes, forward gear clutch is designed to and the direct-connected mode of engine output shaft, finish forward gear clutch by the whole process that is separated to complete combination by hydraulic control, promptly by the operating oil pressure of microprocessor solenoidoperated cluthes, the impacting force that makes clutch is in control range, the combination that makes clutch with separate more smooth-going, thereby play the effect that replaces main clutch, make the speed Control of vehicle become convenient, smooth and easy, simultaneously, production investment and cost have been reduced.
Description of drawings:
Accompanying drawing 1 is an embodiment of the invention structural representation.
Among the figure, 1-gearbox input shaft, 2-clutch planet carrier, 3-hole jump ring, 4-friction plate, 5-dividing plate, the 6-bearing plate, 7-clutch plunger, 8-clutch hub, the 9-fixing bolt, 10-seal ring, 11-clutch oil cylinder, the 12-sun gear, 13-pressure oil control valve, 14-axle jump ring, the 15-belleville spring, 16-planet wheel shaft, 17-initiative taper dish axle.
Embodiment:
The embodiment who provides is in conjunction with the accompanying drawings further specified its structure:
As shown in Figure 1, be provided with forward gear clutch and reverse gear brake in the stepless speed variator casing, provide in the reverse gear brake structure accompanying drawing, its structure is existing the employing in stepless speed variator, and do not have with the present invention direct relation is arranged, and do not do too much explanation at this.Gearbox input shaft 1 front end connects firmly by modes such as spline and engine output shaft.Input shaft 1 is connected with the planet carrier 2 usefulness fixing bolts 9 of forward gear clutch by planet wheel shaft 16, planet carrier 2 and input shaft 1 are rotated synchronously, and the input part and the input shaft 1 that promptly constitute forward gear clutch are linkage manner with engine output shaft rotation synchronously.Forward gear clutch adopts the structural type of wet friction clutch, in this embodiment, the structure of forward gear clutch as shown in Figure 1, it is mainly by planet carrier 2, friction plate 4, dividing plate 5, bearing plate 6, clutch plunger 7, and clutch hub 8, clutch oil cylinder 11, sun gear 12, pressure controlled valve 13, planet wheel shaft 16 are formed; Wherein, driven dividing plate 5 and bearing plate 6 are installed in the groove of clutch hub 8, active friction plate 4 is installed on the planet carrier 2 by spline, and clutch plunger 7 moves in clutch oil cylinder 9, and pressure oil moves in the chamber between clutch plunger and clutch oil cylinder, piston 7 promotes bearing plate 6 and moves along groove, and the force of sliding friction that friction plate is 4 increases, and clutch front and back speed difference is reduced gradually, disappears until the speed difference, realize complete combination, transferring power.During separated state, hydraulic fluid pressure is very little or do not have, and piston 7 does not stress, and the force of sliding friction that bearing plate 6 and friction plate are 4 is very little, and the speed difference is very big before and after the clutch, separated attitude.The rotation of the output control initiative taper dish axle 17 of clutch, clutch hub 8 connects firmly with sun gear 12, sun gear 12 and initiative taper dish axle 17 bindings.Its structure of this embodiment's wet friction clutch is existing the employing in existing stepless speed variator, is mature technology, in this no longer too much explanation.
