Embodiment Construction

[0017] Such as Figure 1~5 As shown, the front end of the diesel engine on the mining vehicle is fixedly supported on the vehicle frame by the present invention. The front support structure of the diesel engine includes a transition body 1 and a support bracket 7. The transition body has an inner hole for the front end of the crankshaft to pass through. The front end of the inner hole is provided with an oil seal 4. Both ends of the transition body have outer cylindrical surfaces. Timing gear chamber 2 crankshaft holes are matched and connected, and the outer cylindrical surface of the front end is connected with the inner hole in the middle of the support bracket. Also be provided with shock absorber 5 on. The front end of the crankshaft is connected with the pulley 6 through the crankshaft flange 3 .

[0018] The support bracket is roughly in the shape of "︺".

[0019] Between the two outer cylindrical surfaces of the transition body is provided a connecting portion for f...

Abstract

The invention provides a novel front support structure of a diesel engine, and the front support structure can enhance the shock resistance of the engine and prevent the fracture of a timing gear chamber, a front support and other parts. The front support structure of the novel diesel engine comprises a transition body and a support bracket, wherein the transition body comprises an inner hole for enabling the front end of a crankshaft to pass through, an oil seal is arranged at the front end of the inner hole, outer cylindrical surfaces are arranged at the two ends of the transition body, the outer cylindrical surface at the back end is matched and linked with the hole of the crankshaft of the timing gear chamber, the outer cylindrical surface at the front end is matched and linked with the inner hole at the middle part of the support bracket, the left end and right end of the support bracket are respectively fixedly supported on frames on the left side and right side of the front end of the engine, and a shock absorber is further arranged on the support bracket.

Description

Technical field [0001] The invention involves a new type of diesel engine support structure. Background technique [0002] Mining vehicles are mainly used for mining engineering. In order to meet the construction of mines, the vehicle and components used by mining cars have considered the mining operating environment, which is more durable and more loaded than the general load.Due to the work of mining cars under the bad conditions such as mine and tunnels, the continuous and severe vibrations have high requirements for engines in terms of earthquake resistance and shock absorption.Under the continuous vibration of the traditional four -point support, it is easy to cause the gear chamber and other parts of the front support to break. Invention content [0003] The technical problem to be solved by the present invention is to provide a new type of diesel engine front support structure, which enhances the engine earthquake resistance and prevent the timing of the timing gear room ...
