Abstract
The utility model discloses a gearbox used for vehicles. The connecting and disconnecting gearbox comprises a planet row clutch and a dead axle gearbox. The planet row clutch mainly comprises a planetary gearing and a multiple disc clutch. The planet row can reach three transmission relationships through operating the multiple disc clutch and a brake belt; a neutral position. The transmitting ratio of a direct gear is 1; 1. The transmitting ratio of a low gear is 1+___; 1. The transmission of power pathway of the utility model is engine motive power-> a planet row clutch gearbox-> the dead axle gearbox-> universal transmission. The utility model adopting the clutch can cancel the operation of stepping the pedal of the clutch, realizes the manipulation of 'accelerating, braking dual pedal', and can simultaneously generate the effect of multiplicative bumper position.
Description
The utility model relates to a kind of vehicular transmission.
Vehicular transmission is all selected fixed shaft type gear-driving speed-variable device usually for use at present.By basic trnasmission with pay a speed changer and cooperate and constitute multi-speed transmission, maximum 12～16 grades of gear, and need that friction clutch of device cuts off or connection power before speed changer, its power transmission approach is:
Engine power → friction clutch → fixed shaft type speed changer → pair speed changer → universal transmission.The NJ130 type of for example making a leapleap forward automotive transmission.Adopt the vehicular transmission of this structure, complex structure, the frequent controlled clutch of driver is easy to fatigue.
The purpose of this utility model is a kind of clutch speed changer of design, and it is not only simple in structure, and can realize " throttle, brake double-pedal " manipulation, makes the car steering simplified control, alleviates driver's labor intensity.
The utility model is made up of planet row's clutch and dead axle speed changer two-part.As shown in Figure 1: on the power input shaft (1) of planet row clutch planet toothrow circle (2) is housed, one end of planet row's pto (9) is contained in the hole of power input shaft (1) right-hand member, central gear (5) is contained on the output shaft (9) by bearing, planet carrier (3) is fixed on the output shaft (9), planet wheel (4) is housed on the planet carrier (3), planet wheel (4) meshes with planet toothrow circle (2) and central gear (5) simultaneously, multiplate clutch active part (8) is connected with output shaft (9) key, multiplate clutch secondary part (7) is housed on the central gear (5), and central gear (5) outer ring is with clamping strap (6).Gear (10), (12), (13), (15) and synchronizer (11) are installed on the dead axle transmission output shaft (14) in the dead axle speed changer, gear (17), (19), (20), (22) and synchronizer (18) are installed on the dead axle transmission countershaft (21), for obtaining different gears, the adjustable positions of synchronizer (11) and (18).
When controlled clutch or clamping strap, planet row has three kinds of drive connections:
1. clutch separation, clamping strap loosens:
At this moment, central gear (5) freely rotates, and planet wheel (4) loses constraint, and the power of gear ring (2) can not be passed to planet carrier, is to be neutral gear.
2. clutch combination, clamping strap loosens:
At this moment, planet is arranged fixed-site between each parts, and planet row is whole with the motor transmission, is to be direct high, velocity ratio: 1:1.
3. clutch separation, clamping strap is stopped tightly:
At this moment, central gear (5) is fixed.Gear ring (2) drives planet wheel (4) around central gear (5) revolution, and planet wheel (4) also has rotation, thereby drives planet carrier (3), output shaft (9) rotation, and its rotating speed turns to identical with engine crankshaft, be to be low grade.Velocity ratio: 1+ (Z central gear)/(Z gear ring): 1 for planet row's clutch and dead axle speed changer two-part are closed in conjunction with gentle, can adopt multi-disc wet clutch.If ask structure and manipulation simple, also can adopt dry clutch.The operation of multiplate clutch and clamping strap can be adopted hydraulic pressure or pneumatic system control, can close and can place on the speed change lever.
The utility model relies on the performance of planet row energy load shift can cancel the operation of stepping on clutch pedal, and realization " throttle, brake double-pedal " is handled, and makes the car steering simplified control, alleviates driver's work.Can also work simultaneously to pay speed changer, produce the effect of gear multiplication, increase Transmission gear, improve the power character and the fuel economy of automobile.Its transmission of power approach is: engine power → planet row clutch speed changer → dead axle speed changer → universal transmission.

Embodiment of the present utility model: with Beijing BJ370 type car is example, and this car adopts clutch to add six grades of dead axle speed changers.Clutch has force aid system.Gear ratio value: (imax)/(imin)=7.437.The utility model cooperates three forward gearss with the planetary clutch speed changer, and the dead axle speed changer of a reverse gear can get six forward gearss equally, and 2 reverse gears can guarantee (imax)/(imin)=7.59.This moment, gear ring was elected 2:1 as with the ratio of the central gear number of teeth.Multi-disc wet clutch selects for use the Shanghai used multi-disc wet clutch of SH380 type car to be enough to deal with the requirement that 6140 h type engine hs are exported 88 kilogram-metre moments of torsion.This moment, each grade relation was as follows:
The number of teeth of each gear is as follows:
Gear ring (2) 64 teeth, planet wheel (4) 16 teeth, central gear (5) 32 teeth, gear (10) 20 teeth, gear (12) 30 teeth, gear (13) 45 teeth, gear (22) 45 teeth, gear (20) 30 teeth, gear (19) 20 teeth, gear (17) 17 teeth, gear (16) 17 teeth, gear (15) 43 teeth.
