Problems solved by technology

At present, the mainstream layout is to install the radiator and air filter on the platform at the rear of the cab, and arrange the exhaust system under the platform at the rear of the cab. High-temperature components make it difficult to arrange the exhaust system, and the arrangement of the exhaust system under the rear platform of the vehicle cab will easily cause the wiring harness and oil pipes on the upper part of the engine and transmission to be too close to the high-temperature components, making it vulnerable to the high temperature of the exhaust

Abstract

The invention discloses an arrangement structure of an air feeding and discharging system and a heat dissipating system of an off-road vehicle. The off-road vehicle comprises a vehicle body platform,the air feeding and discharging system and the heat dissipating system; and the air feeding and discharging system is arranged above the vehicle body platform, the heat dissipating system is arrangedabove the vehicle body platform, and the air feeding and discharging system and the heat dissipating system are oppositely arranged. The invention further discloses the off-road vehicle, adopting thearrangement structure, of the air feeding and discharging system and the heat dissipating system. The air feeding and discharging system of the vehicle is arranged above the vehicle body platform, theheat dissipating system is arranged above the vehicle body platform, the air feeding and discharging system and the heat dissipating system are oppositely arranged, thus a high-temperature part and anon-high-temperature part are arranged in the left-right direction, in the operating process of the vehicle, cold air is absorbed by the heat dissipating system and then directly purged to the high-temperature air feeding and discharging system to cool the air feeding and discharging system and weaken the heat radiation influence of the high temperature of the air feeding and discharging system on other parts of the vehicle, and thus power performance and reliability of the vehicle are improved.

Description

technical field [0001] The present invention relates to the field of vehicle structure technology, in particular to an arrangement structure of an intake and exhaust system and a cooling system of an off-road vehicle and the off-road vehicle. Background technique [0002] Existing heavy-duty off-road vehicles have different arrangements for the intake and exhaust systems and heat dissipation systems of different automobile companies. The general arrangement is to arrange the radiator at the front end of the engine, and the air filter at the left and right sides of the vehicle cab. On the side, the exhaust system is arranged on the side of the vehicle frame. This general arrangement is very suitable for vehicles operating on urban roads. The engine horsepower of the heavy-duty off-road vehicle is large, and the chassis has off-road requirements. The setting of the exhaust system of a heavy-duty off-road vehicle needs to consider the wading height, and generally requires the...
