Multi Cone-Clutch is Applied Retarder}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a retarder to which a multi-cone clutch is applied, and more particularly to a retarder that is formed on a rotating shaft connected to a drive shaft of a vehicle and generates a braking torque, To a retarder including a clutch portion having a cone clutch, wherein the clutch portion is a multiple disc clutch type multi-cone clutch.

Generally, a large vehicle is equipped with an auxiliary brake mounted on a driving wheel in addition to a wheel brake for directly braking the wheel. Such a sub-brake is equipped with a retarder on the driving shaft of the vehicle, The braking force of the wheel brake can be improved as well as the wear of the wheel brake can be improved.

The retarder may be installed at an intermediate portion of the drive shaft, or may be connected to an output end or an input end of the transmission to generate a deceleration torque in the drive shaft of the vehicle.

In addition, the retarder may be divided into an electric type and a fluid type according to an operation mode, and the fluid type retarder is characterized by using a resistance of a working fluid to reduce a rotational force of the transmission rotating at a high speed.

Prior art relating to the retarder described above includes Korean Patent Publication No. 2012-7022041 ("Driving train with hydrodynamic retarder ", 2011.11.5) and European Patent Publication No. 2015972 (" HYDRODYNAMIC MACHIBE " , Jan. 21, 2009).

At this time, in the case of a fluid type retarder applied to a large commercial vehicle, a power transmission device for transmitting a large braking torque must be provided.

Particularly, in the case of using the friction clutch and the dock clutch, when the initial power transmission is performed, the multi-plate clutch smoothly transmits the torque and the large power can be transmitted using the dog clutch.

However, in order to provide the power transmission device, there is a problem that the complexity of the control for transmitting the braking torque and a large space are required.

Particularly, in the case of the dog clutch, there is a concern that a large impact may be transmitted to the driver at the time of engagement, and vibration and noise may be generated.

And the clutch portion of the retarder to which the cone clutch is applied.

A retarder to which a multi-cone clutch according to the present invention is applied is a retarder connected to a drive shaft (1) of a vehicle to generate a braking torque, and is intended to provide a clutch for transmitting a braking torque generated in the retarder .

In particular, the clutch of the retarder to which the multi-cone clutch according to the present invention is applied is a cone clutch, and it is intended to provide a clutch formed in a multi-plate-clutch type.

The retarder to which the multi-cone clutch according to the present invention is applied includes a retarder part 100 for generating a braking torque and a clutch part 200 for transmitting the braking torque generated in the retarder part 100 .

1, the retarder 100 includes a rotor 120 rotating together with a rotation shaft 2 connected to the drive shaft 1, and a rotor 120 rotatably coupled to the rotor 120. The rotor 120 rotates together with the rotor 120, And a stator (130).

The retarder 100 is formed of a fluid type retarder that forms a braking torque by friction between the rotor 120 and the stator 130 according to a fluid filled in the chamber 110 .

The retarder 100, which is the fluid type retarder described above, is a well-known technology, and a detailed description thereof will be omitted.

The clutch unit 200 is formed on the rotary shaft 2 and transmits the braking torque generated from the retarder unit 100 to the drive shaft 1. [

That is, it is recommended that the clutch unit 200 be formed between the drive shaft 1 and the retarder unit 100 on the rotating shaft 2, and that the retarder unit 100 with the multi- The braking torque generated in the retarder part 100 is transmitted to the drive shaft 1 by the fluid filled in the chamber 110 during braking.

2, the clutch unit 200 may include a friction plate 210 and an inner surface of the conical driving plate 220. The clutch unit 200 may include a clutch plate 200, And a cone clutch is provided to transmit the braking torque to the friction clutch.

In this case, the clutch unit 200 having the cone clutch is formed in the form of a multi-plate-clutch in which at least one of the cone clutches is repeatedly formed.

That is, the clutch unit 200 of the retarder to which the multi-cone clutch according to the present invention is applied includes a cone clutch that transmits the braking torque by friction between the outer surface of the conical friction plate 210 and the inner surface of the conical driving plate 220 The braking torque generated by the retarder 100 can be smoothly transmitted to the drive shaft 1 without noise and can be smoothly transferred to the drive shaft 1.

The clutch unit 200 having the cone clutch is formed in a multi-plate clutch so that the braking torque generated in the retarder unit 100 can be smoothly transmitted to the drive shaft 1.

In other words, the conventional dog clutch has a problem that a large impact is transmitted to the driver when coupling to transmit the braking torque, while the clutch part 200 of the retarder to which the multi-cone clutch according to the present invention is applied, Plate-clutch type, there is an advantage that vibration and noise are less than those of the conventional braking torque transmitting device.

As described in the above-mentioned expressions (1) and (2), the cone clutch is more advantageous than the friction clutch

Figure 112015046922261-pat00003
Of the braking torque can be transmitted.

That is, the amount of braking torque transmitted to the drive shaft 10 can be controlled according to the angle a between the height of the friction plate 210 and the drive plate 220 and the bus line.

In other words, as the value of the angle a between the height of the friction plate 210 and the drive plate 220 and the bus line becomes smaller, the capacity of the clutch that transmits the braking torque becomes larger, The capacity of the clutch that transmits the braking torque becomes smaller as the value of the angle a between the height of the braking member 220 and the bus line becomes larger.

This is because the outer diameter of the cone-clutch of the clutch unit 200 for transmitting the braking torque can be made small, which is advantageous not only for a large commercial vehicle but also for a small commercial vehicle and various fields.
