Description
技术领域technical field
本发明涉及一种汽车发动机悬置领域,特别是一种越野汽车大马力发动机悬置。The invention relates to the field of automobile engine mounts, in particular to a high-horsepower engine mount for off-road vehicles.
背景技术Background technique
现有的重型汽车多为平头驾驶室,驾驶室下方是汽车的冷却模块和发动机,冷却模块安装在发动机前方,而发动机安装在驾驶室下方的车架内侧。发动机的悬置通常是采用前管状横梁上焊接斜板固定前减震块、发动机后悬置采用铸造件连接车架内侧斜面来固定后减震装置。当重型越野汽车需要马力大的发动机时,由于大马力发动机的外形比较大,车架内侧安装发动机的空间有限,很容易导致发动机后悬置无法安装在车架内侧,或者是后悬置铸件减小强度来满足安装,更甚至使发动机无法安装,这给发动机装配工作带来了极大的麻烦和困难。从而导致误工、误期,给汽车生产厂家带来经济损失。Existing heavy-duty vehicles are mostly flat cabs, and below the cab are the cooling module and the engine of the car. The cooling module is installed in front of the engine, and the engine is installed on the inside of the vehicle frame below the cab. The suspension of the engine usually adopts the welded slant plate on the front tubular beam to fix the front shock absorber, and the rear suspension of the engine uses castings to connect the inner slope of the frame to fix the rear shock absorber. When a heavy-duty off-road vehicle needs a high-horsepower engine, due to the relatively large shape of the high-horsepower engine, the space for installing the engine inside the frame is limited, and it is easy to cause the rear suspension of the engine to be unable to be installed on the inside of the frame, or the casting of the rear suspension is reduced. The small strength meets the installation, and even the engine cannot be installed, which brings great trouble and difficulty to the engine assembly work. As a result, work delays and delays are caused, and economic losses are brought to automobile manufacturers.
目前的重型越野汽车发动机前悬置多采用管状横梁,后悬置内置车架内侧的铸件来安装发动机。当越野汽车需要大马力的发动机时,这种结构就显得安装空间欠缺和不足,这种结构的缺点是:The front suspension of the current heavy-duty off-road vehicle engine mostly uses a tubular beam, and the rear suspension has a built-in casting inside the frame to install the engine. When the off-road vehicle needs a high-horsepower engine, this structure appears to be short of installation space and insufficient. The disadvantages of this structure are:
(1)管状横梁中的弯管横梁加工误差大,检验员很难校对准确成品件的尺寸,易导致发动机装配不合适;(1) The processing error of the curved pipe beam in the tubular beam is large, and it is difficult for the inspector to check the exact size of the finished product, which may easily lead to improper assembly of the engine;
(2)管状横梁中斜板的焊接很难准确,制造困难;(2) The welding of the inclined plate in the tubular beam is difficult to be accurate and difficult to manufacture;
(3)驾驶室下方车架之间发动机的安装空间狭小,使用铸件有很大的难度。(3) The installation space of the engine between the frames under the cab is narrow, and it is very difficult to use castings.
且同一种车型更换不同马力的发动机,发动机悬置就无法通用,通用程度低。And if the engine of different horsepower is replaced in the same model, the engine mount cannot be used universally, and the degree of universality is low.
