Description
Affiliated technical field
The utility model belongs to the Clutch Technology of stepless speed variator, mainly proposes 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 gear 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 purpose of this utility model promptly provides a kind of forward gear clutch 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 technological scheme that its invention task of finishing the utility model is adopted is: it is arranged in the casing of stepless speed variator, adopts the structure of the wet friction clutch of hydraulic control; Forward gear clutch mainly is made up of planet carrier, friction plate, dividing plate, bearing plate, clutch plunger, clutch hub, clutch oil cylinder, sun gear, pressure controlled valve, planet wheel shaft; Wherein, driven dividing plate and bearing plate are installed in the groove of clutch hub, friction plate is installed on the planet carrier by spline, have in the clutch oil cylinder and promote the clutch plunger that bearing plate moves, clutch hub and sun gear connect firmly, and the input part of forward gear clutch is that the clutch planet carrier connects with the gearbox input shaft by planet wheel shaft and connects with engine output shaft by input shaft; The sun gear of forward gear clutch and initiative taper dish axle pass through splined.
The utility model is designed to forward gear clutch 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
Fig. 1 is the utility model example structure schematic representation.
Among the figure, 1, the gearbox input shaft, 2, the clutch planet carrier, 3, hole jump ring, 4, friction plate, 5, dividing plate, 6, bearing plate, 7, clutch plunger, 8, clutch hub, 9, fixing bolt, 10, seal ring, 11, clutch oil cylinder, 12, sun gear, 13, the pressure oil control valve, 14, the axle jump ring, 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, forward gear clutch and reverse gear brake are arranged in the casing of stepless speed variator, provide in the reverse gear brake structure accompanying drawing, and its structure is existing the employing in stepless speed variator, and not having with the utility model has direct relation, does not do too much explanation at this.As shown in Figure 1, forward gear clutch adopts the structural type of wet friction clutch, in this embodiment, forward gear clutch mainly is made up of planet carrier 2, friction plate 4, dividing plate 5, bearing plate 6, clutch plunger 7, clutch hub 8, clutch oil cylinder 11, sun gear 12, pressure controlled valve 13, planet wheel shaft 16; 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, planet wheel shaft 16 is inserted in the pin-and-hole of planet carrier 2, axle is installed in the groove of sun gear 12 with jump ring 14, belleville spring 15 is installed in axle with between jump ring 14 and the clutch plunger 7, uses so that the piston return.Clutch plunger 7 is arranged in the clutch oil cylinder 11, pressure oil moves in the chamber of 11 of clutch plunger 7 and clutch oil cylinders, piston 7 promotes bearing plate 6 and moves along groove, increase with the force of sliding friction of friction plate 4, the speed difference reduces gradually before and after making clutch, disappear until the speed difference, realize combination, transferring power fully.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.As shown in Figure 1, the input part planet carrier 2 of forward gear clutch is connected with input shaft 1 usefulness fixing bolt 9 by planet wheel shaft 16, input shaft 1 connects firmly with modes such as splines with engine output shaft, constitute the input part and the input shaft 1 of forward gear clutch, the mode that engine output shaft directly connects, rotates synchronously.The output of clutch is that sun gear 12 connects firmly sun gear and initiative taper dish axle 17 bindings with clutch hub 8.Its structure of this embodiment's wet friction clutch is existing the employing in existing stepless speed variator, is mature technology, do not do too much explanation at this.
