Cone clutch is called because the working surfaces of the present clutch are cones.

This invention can be used wherever during the rotation of the shaft there is a need mobile inclusions in rotation and disconnection from the rotation of the secondary shaft. Basically, cone clutch is designed for the automotive industry.

Analogs of this invention can be considered as existing at present, automotive clutch. I changed the shape of the working surface and put extra insurance against slippage of the clutch at high loads. This insurance is made as an additional variable cardan joint intermediate shaft coupling with slotted sleeve shaft.

This work is due to the fact that in heavy-duty machines grip is the least reliable link mechanisms of transmission. This is due to the need to transfer large torque through the contacts of the working surfaces of the disks. To ensure reliable operation of the clutch requires greater effort, gripping the discs. However, at high loads the clutch often slips and burns.

The purpose of this invention is to improve reliability automotive clutch.

Cone clutch is of the friction is, dry, permanently closed clutch spring screw-down mechanism. Like any other friction clutch, cone clutch consists of a leading part, the drive part, the adjusting mechanism and control mechanism clutch, but instead of master and slave drives are master and slave cones. The tapered grip force of the contact, denote it by the symbol N, in contrast to disk, not equal longitudinal force F, clamping the disks to one another, but in 1/sinβ once more. Here β - the angle between the vector force of the spring acting on the movable cone and the direction of the lateral surface of the cone. * The smaller the cone angle, the greater the contact between the master and the slave cones with the same force F. Thus, when β=30° contact force N is equal to 2F. That is, with the same force density contact the tapered clutch two times more than a normal disk. When β=15° N=F/0,26. This is almost 4 times more than F. But the density of contact, the efficiency of coupling. Therefore, according to this indicator cone clutch effective disk. Submitted grip with additional (intermediate) shaft connects directly to the engine with the gearbox, which eliminates thrashing and burning the clutch. This requires that the output shaft of the engine was equipped W is the left main coronary artery, the internal surface of which has slots. The intermediate shaft on which is mounted a leading cone has a grooved surface with dimensions equal to the dimensions of the slotted surface of the bushing output shaft, and one end is always in the sleeve. The sleeve has a through slot with the direction along the axis. In this slot moves the pin, which is inserted in a hole drilled in the intermediate shaft, and to which is attached a ring, or any other device designed to serve as a bearing for clutch release bearing for discharge of the lead cone clutch from the slave. The intermediate shaft has the ability to move along the axis of the sleeve by a distance equal to the length of the slot minus the diameter of the pin. Next on the sleeve with a certain gap from the ring of the release bearing is located. Clutch release bearing is mounted on the lever, connecting it with the control mechanism, leading it in motion. This mechanism may be the pedal, the power cylinder or something else. The thrust bearing must be made in the form of a ring, because inside it is the hub of the motor shaft. The internal diameter of the clutch release bearing is larger than the diameter of the sleeve and it moves freely along its axis. Sleeve ends with a reference edge, which rests against the spring clutch. On the intermediate shaft after the springs of the clutch is leading the cone. It slides along the axis of the shaft on its sleeve. Inside the cone on its sleeve is the reference cylinder. The support cylinder has a possibility of axial movement on the sleeve. It is a spring shaft. One end of the spring abuts against the end ring of the master cone and the other into the side of the support cylinder. In the hub of the primary cone, as in the shaft sleeve, made the cut. In this slot along the sleeve moves the pin connecting the shaft with the supporting cylinder. Spring shaft should be weaker than the spring clutch. Next, the shaft is held in a driven cone clutch. The intermediate shaft rotates in bearings mounted on its hub in a driven cone clutch. Driven cone sits on the sleeve of the drive shaft gearbox (transmission). The inner surface of the sleeve splined and has dimensions equal to the outer splined surface of the intermediate shaft. Between the clutch cone and the clutch cover is installed bearing, which rotates the driven cone. When the clutch (disjoint disks) between the intermediate shaft and splined sleeve drive shaft transmission must be some backlash. When the adhesion of the intermediate shaft with its free end must be in splined bushing drive shaft transmission.

Cone clutch consists of a clutch cover 1, which are the leading 9 slave 10 cones clutch. Driven cone clutch is splined on the sleeve 13 of the drive shaft 12 of the transmission and rotates in its bearing 11. The master cone is located on the intermediate shaft 6, on its spline hub 15 having the capability of translational movement along the intermediate shaft. The intermediate shaft 6 has a splined surface and rotates in its bearing 14. In the master cone on the spline hub 15 moves connected with the intermediate shaft pin 17 of the supporting cylinder 16 with a spring intermediate shaft 8. In the end ring of the master cone rests against the spring clutch 7, which has its other end rests on the support flange 5 splined coupling sleeve of the output shaft of the engine 2. On the sleeve is a ring release bearing 20, the lever 4 is the thrust bearing 3. The support ring 20 is connected with the intermediate shaft 6 with the aid of the rd pin 19, through a hole 23 drilled in the intermediate shaft. In splined coupling sleeve is made through slot 21, which moves the pin 19 with the support ring 20. When the clutch, the intermediate shaft 6 at one end sits in the spline hub of the motor shaft 2, the other end sits in the spline hub 11 of the driving shaft of the gearbox 12. Thus, when the clutch itself contact the clutch off from work, and torque from the engine gearbox is transmitted through the intermediate shaft. Driven cone clutch 10 is located on the sleeve 11 of the driving shaft of the gearbox 12 and, when the clutch rotates with the shaft 6 and the leading cone 9. For the clutch on the clutch lever 4 is force, release bearing 3 presses on the support ring 20, the ring moves along the axis of the shaft attached to the pin 19. The pin leads to the intermediate shaft 6. The intermediate shaft, moving towards the engine out of the hub shaft 13 of the gearbox. At the same time, the intermediate shaft through the pin of the support cylinder 17 has a support cylinder 16. The supporting cylinder, compressing the spring shaft 8 against the end ring of the cone and, overcoming the resistance of the spring clutch 7, takes the lead cone 9 from the slave 10, tearing, thus, chain lane is giving the rotation from the engine gearbox. Upon termination of the force action on the clutch lever, the spring clutch 7, resting one end in the support side of the connecting sleeve 5, and the other in the ring leading cone clutch 9, pushes the leading cone along the axis of the shaft in the direction from the engine. Since the spring clutch 7 is stronger than the spring shaft 8, it's going to work first and then concatenate driving and driven clutch cones. Driven cone clutch is located on the sleeve of the drive shaft gearbox 13. Starting to rotate, it rotates the bushing gearbox 13 with its drive shaft 12. Spring intermediate shaft clutch 8, after a connection was made cones, pushes the support cylinder, and with it the intermediate shaft through a pin 19 inserted in the drive shaft 12. Spring intermediate shaft clutch 8, after a connection was made cones, pushes the support cylinder, and with it the intermediate shaft through a pin 19 inserted into the hole in the shaft 22, the slits in the sleeve lead of the cone toward the gearbox. Because the grip has already occurred, and the sleeve 13 of the primary shaft of the gearbox rotates at a speed equal to the speed of rotation of the engine, an intermediate shaft enters the sleeve 13 of the primary shaft of the gearbox. Thus will come into effect chain for transmitting rotation from the motor cor the BKE gear through the intermediate shaft. If the intermediate shaft will not fall into the slots of the sleeve, with a large force of the engine cones clutch slightly rotated, the slots of the intermediate shaft can find their nests in the sleeve, and walk in them. The intermediate shaft can be hollow and made with internal splines under the splined end of the output shaft and the splined end of the drive shaft of the gearbox may have a blind groove with internal splines, can have from one end of the inner slots, the other external. The use of shaft or sleeve in the connection will depend on the specific design decisions in a particular engine.

Output.

Replacement clutch discs cones and the introduction of the intermediate shaft will increase the reliability of the clutch.
