Description
Technical field
The utility model belongs to the mechanical transmissioning technology field, is specifically related to a kind of double belt stepless speed variator that is synchronized with the movement.
Background technique
Speed changer mainly is divided into manual transmission, automatic transmission and stepless speed variator three types, and wherein, manual transmission is by gearbox drive, and its velocity ratio is 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 automatically according to the speed of the speed of a motor vehicle increase and decrease of gear.
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 less, 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 realizes the stepless variation of speed ratio with transmission between the principal and subordinate wheel.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 to drive wheel.
For so that the output of stepless speed variator is steadily fricton-tight, must guarantee the zygosity between belt and the belt wheel, fricton-tight in order to 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 is only applicable to use on the motorcycle than small displacement.When the stepless speed variator discharge capacity is larger, 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 large, belt the temperature inside the box is high, cause driving belt not durable working life, can't satisfy large discharge capacity car engine to the requirement of 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 cone dish and second and decides the cone 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 cone 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 cone dish both sides, decide the friction plate between cone 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.
Although 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 cone dish, not only lose transmission efficiency, the working life that heat also affects driving belt is given birth in kinetic friction, even driving belt adopts metal tape, also can be owing to the wearing and tearing that produce relative movement quickening driving belt, reduce working life, and the cone dish with transmission is had a negative impact.
Application number is that the Chinese patent of CN 201110110838.2 discloses a kind of double belt stepless speed variator that is synchronized with the movement, stepless speed variator has been realized respectively the first initiative taper dish group and the second initiative taper dish group and first from mantle dish group and second from being synchronized with the movement between the mantle dish group although this double belt is synchronized with the movement, and also has the defective that vibration is large, transmission efficiency is low in running.
