Arrangement for cooling a vehicle component
First Claim
1. An arrangement for cooling at least one vehicle component disposed adjacent to an engine, the arrangement comprising:
- a cooling circuit, the cooling circuit comprisinga line feeding coolant to the vehicle component and a line feeding coolant from the vehicle component, the line feeding coolant from the vehicle component comprises a nonretum valve,a further line feeding the coolant to the engine, anda flow control valve controlling the coolant in the cooling circuit such that the flow of coolant to the vehicle component is lower than the flow to the engine;
a pump feeding the coolant through a first line and then onward, on the one hand, to the line feeding coolant to the vehicle component and, on the other hand, to the further line feeding the coolant to the engine, the flow control valve being arranged along the line feeding coolant to the vehicle component;
a first radiator arranged along the further line feeding the coolant to the engine and a second radiator arranged along the line feeding coolant to the vehicle component, the first radiator and the second radiator being air-cooled.

Abstract
The invention constitutes an arrangement for cooling a vehicle component, for example a transmission, disposed adjacent to an engine, which arrangement includes a cooling circuit designed to feed a coolant through the transmission and including a line for coolant to the transmission and a line for coolant to the transmission. According to the invention, the cooling circuit is also designed to cool the engine and includes a further line for feeding the coolant to the engine, and the cooling circuit includes a flow control valve for controlling the coolant in the cooling circuit such that the flow of coolant to the vehicle component is lower than the flow to the engine. As a result of the invention, an improved arrangement is obtained for cooling, for example, a transmission, for example in heavy goods vehicles.
