Problems solved by technology

It can be said that this technical solution has many advantages compared with the prior art, but this technical solution still has some deficiencies. First, when using this technical solution for installation, firstly, the first sealing groove in the sprocket housing housing should be sealed. The gasket is installed and connected with the cylinder block or cylinder head, but it cannot be completely fixed. After installing the flywheel housing and positioning it, then fixing the sprocket housing, the installation work can be reduced to a limited extent.
The second is that because there is a relative force between the sprocket housing housing and the flywheel housing, the two contacting surfaces cannot prevent the occurrence of oil leakage

Embodiment Construction

[0026] The technical solution of the present invention will be described in detail below through specific examples. It should be understood that the following examples are exemplary only, and can only be used to explain and illustrate the technical solution of the present invention, and cannot be construed as an explanation of the technical solution of the present invention. Program limitations.

[0027] A kind of engine sprocket housing housing, the sprocket housing is formed with a cavity 1 for accommodating a chain transmission mechanism; a hole 2 passing through a camshaft is formed in the cavity 1, and a hole 2 for passing through a camshaft is formed in the cavity 1 Bolt holes for installing tensioner and other components and mounting holes 5 for fixing with cylinder block and cylinder head.

[0028] The first installation surface 3 on the sprocket housing housing is far away from the concave cavity and faces the engine block and cylinder head, and the second installatio...

Abstract

The invention relates to a chain wheel chamber casing of an engine. The upper portion of the chain wheel chamber casing is away from a concave cavity and faces to a first installation surface of a cylinder body and a cylinder cover of the engine, the lower portions on two sides of the chain wheel chamber casing face a second installation surface and a third installation surface of a flywheel casing respectively. A first sealing groove for placing a sealing member is formed in the first installation surface, a second sealing groove is arranged under the first sealing groove, a third sealing groove and a fourth sealing groove are arranged on the second installation surface and third installation surface respectively, and an included angle is formed between the second installation surface and the first installation surface and between the third installation surface and the first installation surface. By means of the technical scheme, sealing members can be well fixed in the sealing grooves, users only need to push a lower side installation surface toward the flywheel casing, installation in one step can be achieved, and many installation procedures are reduced.

Description

technical field [0001] The invention belongs to the field of engine accessories, in particular to an engine sprocket chamber housing. Background technique [0002] Existing automobile engines, in addition to cylinder blocks and cylinder heads, also include valve trains, fuel supply systems, cooling systems, and lubrication systems. During the working process of the engine, the various mechanisms must be closely matched, so the relative angular position of the intake and exhaust cams on the camshaft is adapted to the established valve timing. The camshaft is generally driven by the crankshaft, and the camshaft is driven by a chain transmission mechanism. In order to reduce the volume of the engine, the chain transmission mechanism driving the camshaft is arranged on the flywheel side of the engine. [0003] The chain transmission mechanism is arranged in the engine sprocket chamber housing, which is fitly installed on the engine cylinder head and the cylinder block, and the...
