Claims

[Scope of utility model registration request]

It is equipped with a rotor fixed to the power shaft of the vehicle, a stator surrounding the rotor, an oil cylinder whose intermediate port is connected to the retarder outlet on the outer periphery of the stator via an oil drain pipe, and an oil pushing piston and a circuit closing piston with a return spring provided; an air supply pipe connected to one end of the oil cylinder to operate the oil pushing piston; and an air supply pipe connected to one end of the oil cylinder to operate the oil pushing piston; An oil supply pipe is provided which connects the end port which communicates with and is cut off from the end port and the retarder inlet at the intermediate part of the stator, and an oil cooling heat exchanger interposed in the oil supply pipe, A cooling water circulation system formed to pass through a heat exchanger and an engine cooling system radiator with a main cooling fan is provided, and the oil supply pipe is interposed between the end port and the heat exchanger. A retarder device for a vehicle, comprising: a hydraulic motor; and an auxiliary cooling fan disposed close to the radiator and driven by the hydraulic motor.
