Description

The field of technology to which the invention belongs

The present invention relates to a clutch basket assembly that compensates for clutch disc lining wear, even at a minimal level, accurately and automatically.

In particular, the present invention relates to a clutch basket assembly that compensates for the wear of a clutch disc lining during vehicle driving by keeping the disc load when the clutch is disengaged and the load pressing the disc when the clutch is engaged, constant without compromising driving comfort.

State of the art

The wear that occurs on the clutch disc linings is eliminated by screw, key and clamp or threaded systems already included in current clutch systems. In these systems, wear compensation can be implemented to the extent that the system designs permit. In other words, the amount of wear to be compensated can be fully compensated if the amount of thread lead, screw lead, etc. more than these options. Otherwise, if the wear value is less than the parameter measurement, the systems cannot be activated and the minimum wear cannot be compensated. In all clutch basket assemblies, worm screws, keys, clamps and threads are used in the decimal size range. In this case, the wear that occurs on the lining cannot be compensated instantly and accurately.

In addition, the production of clutch basket assemblies implemented using worm screw, key, clamp or threaded systems is difficult and complex. Therefore, they are high cost configurations. In addition, it is difficult to assemble and produce parts. In this regard, obtaining a standard product in each assembly of the product also creates a problem and leads to a high cost.

Wear causes a change in the load pressing the disc when the clutch is engaged and the load on the disc when the clutch is disengaged and affects the engagement. In addition, encountering these changes adversely affects driving comfort.

Application number TR 2016/02947 refers to a clutch basket assembly with a wear compensation mechanism. The purpose of this assembly is to maintain a constant value of the load on the disc when the clutch is disengaged, the load that presses the disc on the engaged clutch, and the height of the clutch basket assembly, or within a certain range when using the clutch basket assembly in accordance with the present invention. In this application, wear compensation is implemented by detecting a change in the operating position of the diaphragm spring depending on wear by means of sensors.

Application number TR 2018/00225 refers to a double disc clutch basket assembly system. This configuration of the invention relates to a dual disc clutch pressure system designed to prevent wear occurring in clutch systems. The dual disc clutch pressure system according to the present invention is designed to perform separation and clutch processes simultaneously in clutch systems.

As a result, due to the aforementioned shortcomings and the insufficiency of current solutions regarding the subject matter of the invention, it is necessary to carry out development in the relevant field of technology.

Detailed description of the present invention

In this detailed description, the clutch basket assembly (20) according to the present invention is described solely for the purpose of clarifying the subject matter of the invention in a manner that does not create a restrictive effect.

The clutch basket assembly (20) according to the present invention is located in the clutch mechanism (10) shown in FIG. 1. The clutch mechanism (10) is a part of the transmission that allows gear shifting by breaking the connection between the vehicle engine and the gearbox, and its two main elements are the clutch disc (11) and the clutch basket assembly (20). The flywheel (30) is the element that transmits the movement from the vehicle's engine to the clutch and tries to keep this movement constant. When the flywheel (30) rotates, the clutch disk (11) is stationary, however, as soon as their surfaces come into contact with each other, a kind of fixation is realized. Thus, the rotational movement of the flywheel (30) is transmitted to the gearbox and then to the wheels via the clutch disc (11). Over time, the linings (111) of the clutch disc undergo wear, and the clutch basket assembly (20) in accordance with the present invention is used to instantly detect and compensate for this wear.

The main elements of the assembly (20) of the clutch basket, a general view and a sectional view along the line A-A of which are shown in Fig. 2 are as follows: basket (21), diaphragm spring (22), pressure plate (23) and adjusting ring (24). In addition to these elements, the clutch basket assembly (20) has the following elements designed, in particular, to compensate for wear: thrust inclined element (25), adjusting inclined element (26), hook (27), force application sheet (28) and adjusting bolt (29) to compensate for wear.

The specified basket (21), the general view of which is shown in Fig. 5 is a structure that covers and protects the structural members of the clutch basket assembly (20). Basket groove (211) is made in basket (21). In the specified groove (211) of the basket, the specified adjusting bolt (29) is provided to compensate for wear. In the event of wear on the lining (111) of the clutch disc, the adjusting bolt (29) rests against the groove (211) of the basket to compensate for wear.

The main task of said diaphragm spring (22), which can be seen as a whole in FIG. 6, in the clutch mechanism (10), is to ensure engagement by creating pressure on said pressure plate (23) when the driver releases the clutch pedal, and separation by relieving pressure on the pressure plate (23) when the driver depresses this pedal. The diaphragm spring (22) is connected to the basket (21) and is provided with several structures in the form of holes. Two of these holes, made mutually in the same direction, are the grooves (221) of the diaphragm spring, which are wider than the others. One of said slots (221) of the diaphragm spring is preferably aligned with said slot (211) of the basket and is provided with an adjusting bolt (29) to compensate for wear.

The main function of the pressure plate (23), which can be seen in detail in FIG. 3, in the clutch mechanism (10), it is to enable release when the clutch pedal is depressed and engage when the clutch pedal is released to enable gear shifting. The pressure plate (23) is provided with channels, support elements, bevel corners and connecting holes. A corner (231) of the bevel of the pressure plate is provided on the pressure plate, and the support channel (232) of the adjusting inclined element is configured to accommodate said adjusting inclined element (26). On the pressure plate (23) is also engaged the specified force application sheet (28).

The main function of the adjusting ring (24), which can be seen in detail in FIG. 3, in the clutch mechanism (10) is to turn clockwise when wear occurs on the lining (111) of the clutch disc and increase the thickness of the pressure plate (23) by means of the adjusting inclined element (26). The adjusting ring (24) is placed on the pressure plate (23). The adjusting ring (24) is provided with an angle (242) of the bevel of the adjusting ring, a channel (241) of the adjusting ring and a hole (244) for the hook. Said hook (27) engages with said hook hole (244). The adjusting ring tension spring (243) is connected to the free end of the hook (27). The other end of said adjusting ring tension spring (243) is connected to the pressure plate (23) by means of a bolt. When the adjustment ring extension spring (243) is fixedly connected to the pressure plate (23), it is connected to the hook (27) by pulling/attaching. The main task of the adjusting ring tension spring (243) in the clutch mechanism (10) is to pull the adjusting ring (24) onto the hook (27) with which it is connected in case of wear on the lining (111) of the clutch disc.

The main task of the specified persistent inclined element (25) in the mechanism (10) of the clutch is to ensure the operation of other elements of the mechanism by the fact that it remains stable in case of wear on the lining (111) of the clutch disc. On the thrust inclined element (25) located on the pressure plate (23), the inclined surface (251) of the thrust inclined element and the mounting surface (252) of the thrust inclined element are made. In addition, a force application sheet (28) and an adjusting bolt (29) are connected to the thrust ramp (25) to compensate for wear.

The adjusting ramp (26) is located in the support channel (232) of the adjusting ramp on the pressure plate (23). The adjusting inclined element (26) is made with an inclined surface (261) of the adjusting inclined element, and also has a latch (262) of the adjusting inclined element. Said latch (262) of the adjusting bevel is located in said channel (241) of the adjusting ring and engages the adjusting bevel (26) with the adjusting ring (24). The tension spring (263) of the adjustment ramp is connected at one end to a hole made in the adjustment ramp (26). Said tension spring (263) of the adjusting ramp at the other end is connected to the hook (27) by pulling/attaching it. The main function of the adjusting ramp tension spring (263) is to retract the adjusting ramp (26). The main task of the adjusting ramp (26) in the clutch mechanism (10) is to provide clockwise movement by means of the spring (263) to stretch the adjusting ramp when wear occurs on the lining (111) of the clutch disc.

The force application sheet (28) shown in FIG. 3 is bolted to the pressure plate (23) at both ends and is engaged from its central section with the thrust ramp (25). The main purpose of the force application sheet (28) in the clutch mechanism (10) is to allow the thrust ramp (25) to continuously apply the proper force to the pressure plate (23).

The main task of the adjusting bolt (29) shown in FIG. 4, in the clutch mechanism (10), it is to ensure that the thrust ramp (25) is maintained in a stable position by resting on the upper surface of the groove (211) of the basket when wear occurs on the lining (111) of the clutch disc. On the adjusting bolt (29) to compensate for wear, the mounting surface (291) of the adjusting bolt is made corresponding to the specified mounting surface (252) of the thrust inclined element.

In the case of normal operation of the vehicle, when there is no wear on the lining (111) of the clutch disc, the clutch basket assembly (20) continues to operate under normal conditions. Under normal operating conditions, the force application sheet (28) continuously pushes the stop ramp (25) in the -z direction and applies constant pressure to the adjustment ramp (26).

When the lining (111) of the clutch disc begins to wear, first all the pressure from the diaphragm spring (22) is applied to the adjusting ring (24). Then pressure plate (23) and adjusting ring (24), and adjusting ramp (26), adjusting ring extension spring (243), adjusting ramp extension spring (263), force application sheet (28) and hook (27) together with it move in the direction (x) of the motor. This movement in the (x) direction of the motor provides support for the adjusting bolt (29) to compensate for wear on the surface of the groove (211) of the basket. Movement of the thrust ramp (25) in the (x) direction of the motor is prevented by the wear adjusting bolt (29) associated with the thrust ramp (25). This situation results in relieving the pressure applied by the thrust ramp (25) to the adjusting ramp (26) by means of the force application sheet (28) associated with the thrust ramp (25). In this case, a space is formed between the inclined surface (251) of the thrust inclined element and the said inclined surface (261) of the adjusting inclined element. The adjusting ramp tension spring (263) retracts the adjusting ramp (26) clockwise by a distance equal to this space. Then, the latch (262) of the adjuster ramp moves clockwise in the channel (241) of the adjuster ring, and contact is made between the ramp (251) of the thrust ramp and the ramp (261) of the ramp.

When the clutch pedal is depressed, the diaphragm spring (22) is released from the adjusting ring (24). The channel (241) of the adjusting ring rests on the latch (262) of the adjusting bevel, and the adjusting ring (24) rotates on the mirror corner (232) of the bevel. With this rotation, the angle (231) of the bevel of the pressure plate is obtained with a height equal to the amount of wear on the lining (111) of the clutch disc. At the same time, wear compensation equal to the wear on the lining (111) of the clutch disc is provided.

A mounting hole (Z) is provided between the mounting surface (291) of the adjusting bolt and the mounting surface (252) of the thrust ramp in the case of transmission of the clutch basket assembly (20) for assembly on the vehicle. It is provided that the assembly (20) of the clutch basket, which compensates for wear, before being installed on a vehicle with this formed installation space (Z) is passive. In one alternative embodiment of the present invention, the wear adjusting bolt (29) may be supplied separately and then provided for installation on the clutch basket assembly (20). After the clutch basket assembly (20) is installed on the vehicle, the clutch basket assembly (20) is actuated so that wear compensation can be carried out. Actuation of the clutch basket assembly (20) is provided by tightening the adjusting bolt (29) to compensate for wear so that it eliminates the mounting space (Z) and overlaps the mounting surface (291) of the adjusting bolt with the mounting surface (252) of the thrust ramp.

If it is necessary to carry out maintenance in the clutch basket assembly (20), it is necessary to make the active clutch basket assembly (20) passive again. This situation is obtained by loosening or completely removing the adjusting screw (29) to compensate for wear so that an installation space (Z) is formed. Maintenance and/or repair is provided by dismantling the clutch basket assembly (20) after the clutch basket assembly (20) is deactivated to compensate for wear. In order to reinstall the clutch basket assembly (20), the wear adjusting bolt (29) is tightened and the system is actuated by repeating the same processes.

In the system of the clutch basket assembly (20) according to the present invention, there are no structures such as gear wheel, stepped space, etc. Accordingly, without any limitation, wear of any degree can be eliminated accurately and simultaneously with its occurrence. Thus, on the one hand, all required forces, working distances, positions can be achieved, on the other hand, driving comfort can also be ensured. The components included in the design of the clutch basket assembly (20) are easy to manufacture and their cost is very low. Accordingly, the assembly processes can be carried out practically quickly and in a standard manner.
