Abstract

A motor vehicle chassis and a water-cooled internal combustion engine attached thereto has a cooling system comprising coolant-conducting pipes least one radiator element, and a coolant pump produces forced flow in the cooling circuit. A portion of the cooling pipe system as a distributor pipe module is attached to the vehicle's axle support.

Claims (21)

1. A motor vehicle comprising:

a chassis including a front axle support, and a steering gear attached to the front axle support;

a water-cooled internal combustion engine attached to the chassis, the internal combustion engine designed as a rear engine or as a center engine; and

a cooling system including a cooling pipe system, at least two radiator elements fluidly communicating with the cooling pipe system for discharging heat produced by the internal combustion engine, and a coolant pump for producing a forced flow in the cooling pipe system and in the radiator elements;

wherein the cooling pipe system is formed from a plurality of modules and a plurality of quick action couplings that connect the plurality of modules to each other, the plurality of modules include a rear end module, a central module connected to the rear end module, and a distributor pipe assembly, which adjoins with the central module, and which is attached to the front axle support and communicates with the internal combustion engine and the radiator elements;

wherein the radiator elements are located near the front axle support;

wherein the cooling pipe system includes a plurality of coolant conducting pipes; and

wherein the a distributor pipe assembly includes a first supply pipe with a branching portion that branches to a first one of the radiator elements and a first return pipe with a branching portion that branches to the first one of the radiator elements;

wherein the distributor pipe assembly includes a second supply pipe with a branching portion that branches to a second one of the radiator elements and a second return pipe with a branching portion that branches to the second one of the radiator elements; and

wherein the branching portion of the first supply pipe, the branching portion of the first return pipe, the branching portion of the second supply pipe, and the branching portion of the second return pipe are all located in front of the steering gear as viewed in a direction of travel of the motor vehicle.

2. The motor vehicle as claimed in claim 1 , wherein the radiator element mainly transfers heat from the internal combustion engine to ambient air.

3. A method for assembling a motor vehicle having a chassis and an attached water-cooled engine, which comprises:

providing at least two radiator elements of a cooling circuit system near a front of the chassis and providing the cooling circuit with a coolant pump for generating a forced flow in the cooling circuit;

providing the engine near the middle or rear of the chassis;

attaching a distributor pipe module, which is configured to fluidly communicate with the at least two radiator elements and the engine, to a front axle support; and

connecting a wheel suspension with a steering gear to the front axle support;

locating the radiator elements at a front part of the motor vehicle such that forward and return lines of the distributor pipe module branch off to a respective one of the radiator elements, the branching being forward, as viewed in a direction of travel, of the steering gear;

forming the cooling pipe system from a plurality of modules and a plurality of quick action couplings that connect the plurality of modules to each other, the plurality of modules include a rear end module a central module, connected to the rear end module, and the distributor pipe module, which adjoins with the central module, and which is attached to the front axle support and communicates with the internal combustion engine and the radiator elements; and

providing the cooling pipe system with a plurality of coolant conducting pipes.

4. The method as claimed in claim 3 , wherein the step of attaching comprises clamping coolant-conducting pipes to the front axle support.

5. The method as claimed in claim 3 , wherein the radiator element mainly transfers heat from the engine to ambient air.
