Abstract
The utility model discloses a cog-wheel gearing special for electric driven vehicle. The driving mode of the utility model is a motor-a clutch-a gear-shift mechanism-the clutch-a mechanical decelerator-wheels. When a speed variator shifts in the running of the electric driven vehicle, the fore-and-after clutches of the speed variator are all separated, the rotational speed of gears in the speed variator is vanishing, and at this point the utility model makes gears gear teeth peripheral speed entering into meshing vanishing, therefore, can shift swimmingly. The utility model has the advantages of simple structure, high reliability and convenient operation.
Description
A kind of gear change-speed gearing of elec. vehicle.
The utility model is the invention about the elec. vehicle gear change-speed gearing.
At present domestic is that the elec. vehicle of propulsion source does not all install gear transmission with the storage battery, controls the speed of a motor vehicle by the variation of motor speed.The mode of its transmission is as follows:
Electrical motor---gear reducer---wheel
For the electrical motor that makes elec. vehicle all runs on optimum regime under multiple travel conditions (when upward slope, descending, level road, concavo-convex road, crowded location), with loading capacity and the service life (making storage battery avoid heavy-current discharge) that cuts down the consumption of energy and improve storage battery as far as possible.Thereby improve the rideability of vehicle, all install gear transmission in the driving system of external many elec. vehicles, its type of drive is:
Electrical motor---power-transfer clutch---gear transmission---mechanical reducer---wheel
Gear transmission on the elec. vehicle must can be shifted gears in vehicle ' smoothly, so the structure of change-speed box is all complicated, and working accuracy also requires height, common have approximately following several:
1, gear constant-mesh formula--utilize the cover tooth to put into gear
When shifting gears in the vehicle ', will enter ingear gear teeth circumferential velocity and must equate (promptly synchronous), in change-speed box, add synchro, for this reason to guarantee smooth gearshift.
2, gear constant-mesh formula---utilize hydraulic friction clutches to put into gear.
This kind shift of transmission is convenient, but complex structure, tooling cost is higher.
3, epicyclic gear transmission---similar to the automatic transmission with hydraulic torque converter that uses on the automobile, complex structure, the working accuracy height, driving efficiency is lower.
The purpose of this utility model is a kind of elec. vehicle change gear transmission of design.Wherein speed changer structure is simple, and handling ease is with low cost, and is easy to operate, and functional reliability and durability significantly improve, and driving efficiency is also high.
Task of the present utility model is finished like this: set up a power-transfer clutch between the change-speed box of battery-driven car and drive wheel, when shifting gears in the vehicle ', with this disengaging of clutch, make the motional inertia of vehicle not pass to change-speed box, make again that each gear rotational speed goes to zero in the change-speed box, so just make to equate, guarantee that gearshift smoothly entering gears in mesh gear teeth circumferential velocity.Type of drive of the present utility model now is illustrated in conjunction with Fig. 1 as shown in Figure 1.
Electrical motor among Fig. 1 (1) reaches moment of torsion by power-transfer clutch (2) input shaft (4) of change-speed box (3), cliding gear (7) engagement on driving gear on it (6) and the output shaft (9) reaches output shaft (9) with moment of torsion, reaches mechanical reducer (11) with drive wheels (12) by power-transfer clutch (10) again.When vehicle need be shifted gears under steam, earlier power-transfer clutch (2) (10) is all separated, at this moment the inertia of the inertia of electrical motor (1) and vehicle all passes less than change-speed box, use brake equipment (13) that input shaft (4) is braked then, when its rotating speed goes to zero, gearshift immediately, make cliding gear (8) and driving gear (5) engagement, enter ingear gear teeth circumferential velocity and also go to zero this moment, so can shift gears smoothly, power-transfer clutch (2) (10) engaged with powered vehicle again.
On small-sized electric vehicle,, can save power-transfer clutch (2) because electrical motor is less, power-transfer clutch (10) can adopt overriding clutch or unidirectional self-acting clutch etc., utilizes motor braking during gearshift, and structure is simplified more, during the power requirement reversing, overriding clutch can be pinned.
When the utility model is shifted gears in vehicle ', the gear rotational speed of change-speed box is gone to zero, so need gear braking to change-speed box, brake mode can adopt mechanical braking (band-type brake, lock etc. rises), also can adopt electric braking, the inertia of tumbler can be changed into electric energy input storage battery as carry out regenerative brake with electrical motor.
Claims (3)
1, a kind of gear change-speed gearing of elec. vehicle, it comprises that electrical motor, power-transfer clutch, gear transmission, mechanical reducer, wheel, power reach wheel by electrical motor according to said sequence, it is characterized in that between the output shaft of gear transmission and the wheel (drive wheel) power-transfer clutch being housed, during gearshift, can make the unlikely change-speed box of passing to of motional inertia of vehicle.
2, driving device according to claim 1 is characterized in that the input shaft of gear transmission has drg.
3, driving device according to claim 1 is characterized in that the power-transfer clutch behind the change-speed box can adopt overriding clutch and overriding clutch locking device or unidirectional self-acting clutch etc.
