Abstract
The invention relates to a speed-changing gear box with a built-in clutch. The speed-changing gear box is provided with multiple gear pairs arranged on the same hollow shaft. The built-in clutch mechanism is disposed in the hollow shaft. When a cam moves in the axial direction to push a jaw to an inner hole groove of an output gear, the output gear, the jaw and the hollow shaft are driven at the same speed; when the cam moves away and the hollow shaft is at a neutral gear, the cam moves to be in contact with a new jaw and push the new jaw into a new output gear, and gear shifting and speed changing are completed. By controlling the displacement of the cam, the speed changing and gear shifting are controlled, so that gear shifting during driving and stopping of vehicles is quite convenient and gear positions are unlimited. By using spiral driving and spring buffering, impact during gear shifting is reduced. Due to double combination of friction and rigid force during the combination of the jaws and gear grooves, gear shifting is performed in an ease way. The combination depends on the bearing of the cam, reliable combination and complete separation are achieved, collision during gear shifting is avoided, and safe and more comfortable driving is achieved.
Description
Technical field
A kind of built-in clutch gear gearbox, has multipair gear pair, is arranged on same tubular axis, and the built-in clutch mechanism of tubular axis, with the contacting pushing or leave return and reach gear pair shift speed change an of cam, has realized the automobile-used gear graduation transmission of manipulation automatically of many gears number.
Background technique
The high compact structure of gear graduation efficiency, has some setbacks but shift gears, and gear spacing is large, is difficult to many gear numbers, manipulation inconvenience.
Automatic catch adopts hydraulic machine transmission, expends extra kinetic energy, increases oil consumption; The speed governing of steel-belt type CVT stepless speed-varying vehicle must oil pressure brute force make belt wheel deciliter, has reduced efficiency and life-span.
Gear-box manual shift, manipulation inconvenience, impact is inevitable, drives happy not.
Summary of the invention
A kind of built-in clutch gear gearbox, has multipair gear pair, increases and decreases gradually and is arranged on tubular axis by velocity ratio, the built-in clutch mechanism of tubular axis, by the inner axial tube displacement of a cam, reach each output gear and be subject to combination or the disengaging of clutch mechanism, complete gear shift.
Each output gear endoporus is made groove and is bearing on tubular axis with bearing, it is jaw components (being designated hereinafter simply as claw) that tubular axis cinclides is equipped with clutch mechanism, external end head enters the groove of output gear, the inner puts in tubular axis inside, when the cam contact claw inner termination in tubular axis and promote claw and do footpath and outwards move and enter output gear axle groove maximum inner diameter place, at this moment output gear drives the synchronized rotation of claw and tubular axis and cam, output torque, footpath differential mechanism associated gear and semiaxis again, until drive wheel.Cam is removed, and claw resets under spring force, and external end head and output gear endoporus are separated, and tubular axis is in idle running gear, and cam continues displacement, at another gear, claw is promoted again, becomes new gearshift.
Each output gear is with being placed on a tubular axis, so gear number is not limit, clutch process is identical, and manipulation is convenient.The distance of moving that only needs to control cam, just produces neutral or required gear, and the movement of cam is manipulated by screw pair or hydraulic parts set a distance.
Connect input shaft from power or motor, row's driving gear is housed on it, make every pair of gear produce different rotating speeds, be that gear rotating speed output as long as cam is shifted in that gear, and be convenient to automatic control.Here describe the structure shape feature of built-in clutch mechanism in detail.
1. Double-spring clutch mechanism
Double-spring has upper and lower two sleeve springs, and claw divides upper and lower two.Doing footpath when cam promotion inner termination outwards moves, lower spring compression, pawl body band pawl cover rises simultaneously or pawl cover was pressed onto in fillet of gear week and do not enter in groove, at this moment gear is not with pawl body and tubular axis to rotate, claw external end head and bore are done friction pair transmission and have been produced frictional force, but claw external end head enters groove after aiming at gear groove, the synchronized rotation of gear and claw and tubular axis, in conjunction with success.When cam leaves claw inner termination, lower spring power resets claw, and claw upper tip and gear groove depart from, and stops transmitting, and claw is in neutral, and tubular axis is made inertia and rotated or stop operating.
Dual spring claw can enter or depart from the output gear of any gear at any time, so can shift speed change in motion or completely parking.
List spring clutch mechanism, pawl body is fixed with one, distance between interior external end head immobilizes, its value is that gear groove maximum radius subtracts cam maximum radius, so cam is gradually claw to be promoted to footpath outwards to move after shifting near claw inner termination, claw external end head rises to maximum radius place gradually along gear arc groove, then by gear driven claw and tubular axis and the synchronized running of cam.Once cam is removed, claw inner termination loses supporting, and the curved surface pushing force of spring force and gear inner groovy just resets claw, has stopped conflict in gearshift.
Tubular axis is hollow drive shaft, synchronized rotation while being combined with claw by certain gear gear, and transmitting torque is to the gear pair of differential mechanism.Each claw, by lasso fixed tubular axle cinclides, is subject to the promotion of cam and works.
Cam is done axial displacement in neutral or any gear by screw pair or hydraulic transmission, withstands claw inner termination, is namely supporting claw, and claw external end head is combined in to transmitting torque in gear groove.Cam is bearing on bearing, and bearing slippage on slippage bar, has screw pair in slippage bar, is with dynamic bearing and cam to do axial displacement when nut moves, and is cushioned when having spring that cam is moved axially and being subject to clutch action power, has reduced the impact of gearshift.

Embodiment
From Fig. 1,13. motor, 8. driving tooth schedule, 7. output gear schedule, 3. jaw components, 5. tubular axis, 6. cam, 11. screw rods, 5. tubular axis, 12. gear-boxes, 9. differential gear, 10. differential mechanism gearwheel.
Power or motor (13) connection gear box (12), input shaft connects row's driving gear (8), and transmission output, output gear (7) endoporus make groove and with claw (3) in the promotion of cam (6) and combination, output gear (7) with claw (3), tubular axis (5) and cam (6) with turning.(5) outputs of tubular axis connect with gear (9), then transmission gearwheel (10) and driving wheel thereof.If wedge cam (6) departs from original claw (3), and new claw
the groove that enters a new gear output gear (7) completes gear shift.
In Fig. 2, single spring-loaded pawl and output gear groove combined structure, jaw components lower end (3) contacts in the large footpath of cylinder place with cam (6), claw upper tip (4) contacts power transmission with the groove of output gear (7), the lasso (2) of claw is bearing in tubular axis (5) cinclides, output gear (7), jaw components (3) and tubular axis (5) at this moment and the synchronized rotation of cam (6).
In Fig. 3, output gear is made arc groove
