Abstract
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.
Description
BACKGROUND OF THE
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.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a retarder which is formed on a rotary shaft connected to a drive shaft of a vehicle and generates a braking torque, And a clutch portion provided with a cone clutch to which the multi-cone clutch is attached, wherein the clutch portion is a multi-plate clutch type multi-cone clutch.
A retarder to which a multi-cone clutch according to the present invention is applied is connected to a drive shaft of a vehicle to generate a braking torque. The retarder includes a rotor rotating through a rotation shaft connected to the drive shaft, A retarder portion including a stator being provided; And a clutch part formed on the rotating shaft and having a cone clutch for transmitting braking torque by friction between the outer surface of the conical friction plate and the inner surface of the conical driving plate, Clutch type in which the clutch is repeatedly formed.
Particularly, the friction plate and the driving plate are characterized in that the angle between the height and the bus line is 0 to 90 degrees.
The retarder to which the multi-cone clutch according to the present invention is applied is formed in a rotary shaft connected to a drive shaft of a vehicle and generates a braking torque. The retarder includes a cone clutch formed on the rotary shaft and transmitting a braking torque And the clutch portion is formed in a multi-plate-clutch type, so that when the same braking torque is transmitted, the clutch can be designed to be smaller than a general friction clutch.
In particular, since the retarder to which the multi-cone clutch according to the present invention is applied can be designed to be smaller than a general friction clutch, it can be applied not only to a large commercial vehicle but also to a small commercial vehicle.
Further, the retarder to which the multi-cone clutch according to the present invention is applied has the advantage of less vibration and noise compared to a general friction clutch by forming the cone clutch in a multi-plate-clutch type.
