Abstract
The utility model relates to an automobile variable speed transmission, which is an automobile metal belt type infinitely variable speed transmission, and comprises a driving pulley, a driven pulley, a forward backward gear and a hydraulic torque converter, and further comprises a converter clutch, a planetary gear mechanism and a flywheel, wherein a main transmission route comprises the converter clutch, the driving pulley, the driven pulley, the forward backward gear and the hydraulic torque converter, and an auxiliary transmission route which is parallel to the main transmission route comprises the planetary gear mechanism and the flywheel. The automobile variable speed transmission forms the auxiliary transmission route through the planetary gear mechanism and the flywheel, the planetary gear mechanism carries out a variable speed function, when a driver requires to increase speed, the rotational speed of an engine is increased, the rotational speed of the flywheel is reduced, the self energy is released, and the auxiliary power is provided. When a driver requires to reduce the speed, the rotational speed of an engine is reduced, the rotational speed of the flywheel is increased, and the kinetic energy of a system is absorbed and stored.
Description
Technical field
The utility model relates to a kind of automobile variable speed transmission device, automobile metal Belt-type Adjustable-speed Drive device specifically.
Background technique
Automobile metal Belt-type Adjustable-speed Drive device uses the velocity ratio of continuous controllable, the speed between coupling motor and the automobile and the relation of moment of torsion, guarantee that motor always works on the best effort line or near.But conventional automobile metal Belt-type Adjustable-speed Drive device exists by the transmission of power retardation phenomenon of accelerator pedal to the driving wheel reaction when realizing optimal fuel economy.This transmission of power retardation phenomenon is caused by motor dynamic characteristic, infinitely variable speed transmission time of implementation, infinitely variable speed transmission dynamic characteristic etc., has greatly influenced the cornering ability of stepless change automobile.
Summary of the invention
The purpose of this utility model is to propose a kind ofly can provide auxiliary energy when driver requested fast acceleration, improves the automobile metal Belt-type Adjustable-speed Drive device of stepless change car steering performance.
The purpose of this utility model can be achieved through the following technical solutions:
Automobile metal Belt-type Adjustable-speed Drive device, comprise driving pulley, driven pulley, backward gear and fluid torque converter advance, also comprise conversion clutch, planetary gears and flywheel, conversion clutch and driving pulley, driven pulley, advance backward gear and fluid torque converter composition main transmission route, planetary gears and flywheel are connected to form the auxiliary driving route parallel with the main transmission route.
The purpose of this utility model can also further realize by following technical measures:
Aforesaid automobile metal Belt-type Adjustable-speed Drive device, wherein said conversion clutch is located at before the driving pulley, is used for interrupting the transmission of power by the main transmission route when driver requested fast acceleration.
Aforesaid automobile metal Belt-type Adjustable-speed Drive device, the sun gear of wherein said planetary gears links to each other with flywheel, the gear ring of planetary gears links to each other with automobile power input end (motor direction), and the planet carrier of planetary gears links to each other with automobile power output terminal (driving wheel direction).
Advantage of the present utility model is: form the auxiliary driving route by planetary gears and flywheel, planetary gears is carried out speed changing function, when driver requested fast acceleration, when engine speed is risen, the flywheel rotating speed descends, and discharges self-energy, and auxiliary power is provided; When driver requested deceleration, when engine speed descended, the flywheel rotating speed rose, absorption, stocking system kinetic energy.Conversion clutch interrupts the transmission of power by the main transmission route when driver requested fast acceleration, further improve the effect of auxiliary power.Particularly when driver requested fast acceleration, auxiliary power that flywheel provides and conversion clutch have weakened the influence that transmission of power lags behind to the interruption of main transmission route, have improved the cornering ability of stepless change automobile.Flywheel also plays the peak clipping effect in power transmission process simultaneously, has reduced vibration, impact.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Embodiment one
The structure of present embodiment as shown in Figure 1, a kind of automobile metal Belt-type Adjustable-speed Drive device, comprise the original driven pulley 1 of common metal Belt-type Adjustable-speed Drive device, driving pulley 2, the backward gear that advances, fluid torque converter etc., also comprise conversion clutch 3, flywheel 4, the planetary gears 5 of increase.On original power transmission route, increase conversion clutch 3, form the main transmission route, under the cruising operating mode, use.Connect with planetary gears 5, flywheel 4, form parallel auxiliary driving route, when driver requested fast acceleration, provide auxiliary energy.Before conversion clutch 3 is added in the driving pulley 2 of main transmission circuit, be used for when driver requested fast acceleration, interrupting transmission of power, further improve the effect of auxiliary power by the main transmission route.Planetary gears 5, flywheel 4 form in the auxiliary driving route, the gear ring of planetary gears 5 links to each other with front automobile power intake (motor direction), planet carrier links to each other with rear automobile power output terminal (driving wheel direction), sun gear links to each other with flywheel, carries out speed changing functions by planetary gears 5, when driver requested fast acceleration, when engine speed is risen, flywheel 4 rotating speeds descend, and discharge self-energy, and auxiliary power is provided; When driver requested deceleration, when engine speed descended, flywheel 4 rotating speeds rose, absorption, stocking system kinetic energy.
In automobile actual travel process, the infinitely variable speed transmission controller is gathered the throttle opening signal, when confirming driver requested fast acceleration, conversion clutch 3 separates rapidly, interrupt transmission of power by the main transmission route, pass through the speed changing function of planetary gears 5 simultaneously, when engine speed rises, flywheel 4 rotating speeds are descended, discharge self-energy, auxiliary power is provided, weaken the motor dynamic characteristic, the stepless gear system time of implementation, the transmission of power retardation phenomenon that stepless gear system dynamic characteristic etc. causes, accelerated to have improved the cornering ability of stepless change automobile by the reaction time of accelerator pedal to the driving wheel transmission of power.The stepless gear system controller is gathered the engine rotation speed sensor signal, and when actual engine speed arrived rotating speed of target, conversion clutch 4 engaged again, recovers the main transmission route.
The utility model can also have other mode of execution, and the technological scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
