Power takeoff at rear end of engine

Abstract

The invention discloses a power takeoff at the rear end of an engine. The power takeoff comprises a power takeoff input end, a power takeoff output end and a power takeoff housing, wherein a bearing cavity, in which a bearing can be mounted, is formed in the power takeoff housing; the power takeoff housing can be arranged on a flywheel housing in an embedded manner, and is in detachable connection with the flywheel housing; a lubricating oil channel communicated with the bearing cavity is arranged at the part, embedded in the flywheel housing, of the power takeoff housing. As the power takeoff housing can be arranged on the flywheel housing in an embedded manner, and is in detachable connection with the flywheel housing, the problem that the power takeoff at the rear end of the engine is difficult to dismount and mount in the prior art is solved; as the lubricating oil channel communicated with the bearing cavity in the power takeoff housing is arranged at the part, embedded in the flywheel housing, of the power takeoff housing, the interior of the power takeoff can be lubricated directly; compared with the conventional method in which the bearing in the power takeoff is lubricated by adopting a circumscribed oil passage, not only the inner mounting space of the engine but also the production cost are reduced.

Description

technical field [0001] The invention relates to the technical field of engine power take-offs, in particular to an engine rear end power take-off. Background technique [0002] With the continuous development of society, the demand for heavy-duty cement mixer trucks and large-tonnage special vehicles in the market has increased greatly, and there has been a lack of matching between the power take-off device of the engine and the power system of the vehicle, which seriously affects the power system at the upper end of the engine. The main reason is that the power take-off is mainly directly driven by the belt through the crankshaft pulley at the front end, which not only has the disadvantages of small output torque and high noise, but also easily causes damage to the power take-off device and even the engine itself. shortened lifespan. [0003] Therefore, a rear-end power take-off driven by the crankshaft gear at the rear end of the engine is produced. The main working princ...

AI Technical Summary

Problems solved by technology

[0004] Although the current rear-end power take-off overcomes the shortcomings of small output torque and high noise of the front-end power take-off, the casing of the current power take-off and the casing of the engine flywheel are cast into an integral structure, resulting in disassembly and assembly of the power take-off. It is very inconvenient, and the lubrication of the bearings in the power take-off needs to be realized through the external oil passage, which not only causes the inner space of the engine to be crowded, but also increases the manufacturing cost
