Description

The double belt stepless speed variator that is synchronized with the movement
Technical field
The utility model belongs to the mechanical transmissioning technology field, particularly relates to a kind of stepless speed variator.
Background technique
Speed changer mainly is divided into three types of manual transmission, automatic transmission and stepless speed variators, and wherein, manual transmission is by gearbox drive, and its velocity ratio is a definite value.And automatic transmission is to utilize the speed of a motor vehicle and load to carry out two-parameter control, also is the step type speed changer, and only automatic transmission can realize the increase and decrease of gear automatically according to the speed of the speed of a motor vehicle.
The maximum difference of stepless speed variator and step change transmission is that the gear ratio of stepless speed variator is continuous value, stepless speed variator is simpler compared to traditional speed changer structure, volume is littler, has not both had numerous gear pairs of manual transmission, does not also have the planetary gear set of automatic transmission complexity.Stepless speed variator mainly relies on the band transmission between the principal and subordinate wheel to realize the stepless variation of speed ratio.Variable Speed Technology CVT (Continuously Variable Transmission) adopts the incompatible transferring power that matches of the band transmission between the variable driven wheel of working diameter, can realize continuously changing of velocity ratio, thereby obtain the optimum Match of velocity ratio and engine operating condition.Main pulley receives the transmission power from motor, and by the band transmission power is sent to time belt wheel, by the output shaft outputting power with driving wheel.
In order to make the output of stepless speed variator steadily fricton-tight, must guarantee the zygosity between belt and the belt wheel, fricton-tight so that power is exported between belt wheel and driving belt stably.Yet often with single driving belt transmission, the frictional force between driving belt and the belt wheel is little for existing stepless speed variator, and belt also needs to possess the requirement of bearing certain pulling force, and such stepless speed variator majority all only is applicable on the motorcycle of less discharge capacity and uses.When the stepless speed variator discharge capacity is big, the stepless speed variator of existing single belt transmission does not satisfy the demand of transmission effect, belt easily skid and the transmission power loss of tests big, belt the temperature inside the box height, cause driving belt not durable working life, can't satisfy of the requirement of big discharge capacity car engine stepless speed variator.
The patent No. is the stepless speed variator that the Chinese patent of ZL200820080612.6 discloses a kind of bimetallic strip transmission, this stepless speed variator contains initiative drive shaft, passive transmission shaft, being separately positioned on first on initiative drive shaft and the passive transmission shaft decides awl dish and second and decides the awl dish, being arranged on slides vertically on the initiative drive shaft and be arranged symmetrically in first decides the first mantle dish and the second mantle dish of awl dish both sides, being arranged on slides vertically on the passive transmission shaft and be arranged symmetrically in second decides the 3rd mantle dish and the 4th mantle dish of awl dish both sides, decide the friction plate between awl dish and the mantle dish and connect initiative drive shaft and passive transmission shaft between the first transmission metal tape and the second transmission metal tape.
Though this stepless speed variator has also been realized the double belt transmission to a certain extent, but owing to do not realize between the first mantle dish and the second mantle dish and the 3rd mantle dish and the 4th mantle dish being synchronized with the movement, can't guarantee that in use the displacement distance between the first mantle dish and the second mantle dish and the 3rd mantle dish and the 4th mantle dish equates, when the situation that displacement distance do not wait occurring, can cause the velocity ratio of both sides driving belt inconsistent, and then cause producing relative movement between driving belt and the awl dish, not only lose transmission efficiency, the working life that heat also influences driving belt is given birth in kinetic friction, even driving belt adopts metal tape, also can accelerate the wearing and tearing of driving belt owing to producing relative movement, reduce working life, and the awl dish of band transmission is had a negative impact.
