Background technique
In the flywheel casing of our common clutches between motor and gearbox, be fixed on the back plane of flywheel with screw by clutch assembly, the output shaft of clutch is exactly the input shaft of gearbox.In vehicle traveling process, driver can step on as required or release the clutch pedal, and motor and gearbox is temporarily separated and engages gradually, to cut off or to transmit the power that motor inputs to speed changer.Clutch is the common components in mechanical transmission, transmission system can be separated at any time or engage.Have its basic demand: smooth engagement, be separated rapidly and thoroughly; Regulate and repair conveniently; Overall sizes is little; Quality is little; Wear resistance is good and have enough heat dissipation potentiaies; Easy to operate, conventional be divided into castellated with friction type two class.
Existing clutch configuration is complicated, generally include the structures such as flywheel, pressing plate, friction disk, damper disk, driven disc, clutch plate hub, so many structure also makes the overall volume of existing clutch also relatively large, so not too suitable when the clutch of said structure is used in automobile starting.
Model utility content
For the defect that above-mentioned prior art exists, it is simple that the purpose of this utility model is to provide a kind of structure, and small volume, is applicable to the spiral engaging and disengaging gear of automobile starting.
For achieving the above object, the technical solution of the utility model is:
Spiral engaging and disengaging gear, comprise housing and actuating motor, also be provided with main shaft, friction wheel, friction disk and position limited gear, described main shaft one end is connected with housing into rotation, the other end and friction disk coaxially arranged, and be rotationally connected, the output terminal of described actuating motor is connected shell one end and connects with main shaft, friction disk is coaxially connected with engine crankshaft, screw thread is provided with in the middle part of main shaft, described friction wheel is connected with spindle thread, friction wheel comprises friction section and spacing section, described friction section is near friction disk side, described position limited gear is fixedly connected on housing, spacing section of position limited gear and friction wheel is engaged.
When adopting technique scheme, during car engine, open actuating motor, output terminal because of actuating motor is connected shell one end with main shaft and connects, so actuating motor drives main axis, again because friction wheel is connected with spindle thread, and spacing section of friction wheel is engaged with position limited gear, and position limited gear is fixedly connected on housing, so friction wheel can not rotate and can only move, when friction wheel moves to friction section and friction disk compresses, friction section relies on friction wheel to drive friction disk to rotate, friction disk is coaxially connected with the crankshaft of motor, so crankshaft rotation, until during the rotating speed of the startup rotating speed of motor higher than main shaft, friction wheel is driven to rotate by friction disk, and rotational velocity is greater than the rotating speed of main shaft, now, if take friction wheel as object of reference, main shaft rotates backward, so friction wheel just can be thrown off with friction disk, and move towards the direction away from friction disk.So far, automobile completes start-up course.Structure of the present utility model mainly comprises main shaft, friction wheel, friction disk and position limited gear, simpler than existing common clutch a lot of in obvious structure, so the volume of entirety also reduces relatively, uses when being applicable to automobile starting.
Further, the cross section of described friction section is taper, and friction disk is provided with the cone tank of the ring-type of friction fit section.Such can make friction section and friction disk area of contact larger.
Further, described friction disk is provided with radiation hole.Can produce a large amount of heats in friction section and friction disk friction process, temperature is crossed high coefficient of friction and can be reduced, so need to be drained by the heat distributed in time, radiation hole can accelerate distributing of heat.
Further, friction disk is provided with radiator shutter away from friction wheel side.Can produce a large amount of heats in friction section and friction disk friction process, temperature is crossed high coefficient of friction and can be reduced, and arranging radiator shutter then can forced heat radiation, ensures that the temperature of friction section and friction disk can not be too high.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model spiral engaging and disengaging gear embodiment.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference character in Figure of description comprises: main shaft 1, housing 2, spacing section 3, position limited gear 4, friction wheel 5, friction disk 6, friction section 7, radiation hole 8, radiator shutter 9, cone tank 10.
As shown in Figure 1, a kind of spiral engaging and disengaging gear, comprise housing 2 and actuating motor, also be provided with main shaft 1, friction wheel 5, friction disk 6 and position limited gear 4, main shaft 1 one end and housing 2 are rotationally connected, the other end and friction disk 6 coaxially arranged, and be rotationally connected, the output terminal of actuating motor is connected housing 2 one end and connects with main shaft 1, friction disk 6 is coaxially connected with engine crankshaft, screw thread is provided with in the middle part of main shaft 1, friction wheel 5 is threaded with main shaft 1, friction wheel 5 comprises friction section 7 and spacing section 3, friction section 7 is near friction disk 6 side, position limited gear 4 is fixedly connected on housing 2, spacing section 3 of position limited gear 4 and friction wheel 5 is engaged.
In the present embodiment, the cross section of friction section 7 is taper, and friction disk 6 is provided with the cone tank 10 of the ring-type of friction fit section 7.Such friction section 7 and friction disk 6 area of contact of making is larger.
