Abstract

The invention relates to the air cleaner of the inclined cylinder engine, which provides a device with the compact structure and the conveniently dismantled air cleaner. The technical scheme in this invention is: the air cleaner locates below the inclined end of the inclined cylinder. Its outermost end locates in the overall dimension range of the diesel horizontal direction limited by the cylinder cover. The institution makes full use of the idle space and makes the engine more compact. The vibration of the air cleaner is weakened by using the up-down double rubber damping structure, which can prolong the parts span and reduce the noise. A special designing lock blade is adopted matching the bolted connection to facilitate the disassembling and maintenance of the air cleaner.

Description

A kind of air inlet system of diesel engine

Technical field

The present invention relates to a kind of air inlet system of diesel engine, particularly relate to the air-strainer setting of diagonal-cylinder type diesel engine, belong to field of power equipment technology.

Background technique

The miniaturization of motor for a long time is the problem that people study always, but the air-strainer operated by rotary motion of conventional engines on the top of cylinder block, the motor volume of this arrangement is bigger, structure is compact inadequately, is unfavorable for the miniaturization of motor.

The multilayer punching press, the normal processing of connection between the sheet metal part is portalled and is, realize with one group of bolt, but because engine structure is compact day by day, the assembling work space is narrow and small day by day, the operator usually occurs and hand can't be stretched into the situation of removing to screw connecting bolt or nut in the small gap, the common method that addresses this problem at present is: 1. get out the unthreaded hole that is slightly larger than the bolt nominal diameter earlier on the innermost layer member that need connect, again a nut is aimed at the back side that described unthreaded hole is welded on sheet material, perhaps 2. select described innermost layer material enough thick, direct tap out hole thereon, during connection bolt is passed hole pre-drilled on each layer member, be tightened on the above-mentioned nut that is welded on the member or be tightened on the tapped hole of tapping in advance.Such method need be holed+weld or hole+tapping a member, and for bigger, the complex-shaped thin-walled member of volume, not only processing very bothers, and will guarantee that good assembling interchangeability is also very difficult.

Summary of the invention

Technical problem to be solved by this invention provides a kind of diagonal-cylinder type engine air filter device of compact structure.

Technological scheme of the present invention is: a kind of diagonal-cylinder type motor comprises body, cylinder head, air-strainer, connection support.Air-strainer is arranged on the below of inclination one side of tilting cylinder block, and the outermost end of air-strainer is positioned at the diesel engine substantially horizontal overall sizes scope that cylinder head limits.

The air-strainer upper end is fixed on the motor by the motor connecting plate, and the lower end is fixed on base by the base connecting plate and connects support.Respectively there are two place's tie points at two ends up and down, and all accompany Rubber shock-absorbing pad between junction surface.Because narrow and small, the operating difficulties of connection part working space of air-strainer lower end, for this reason specialized designs a kind of grafting locking plate.Locking plate curves narrow reverse U shape shape, and the U-shaped A/F is connected the sheet metal thickness of support with base similar, has the hole that is slightly larger than the connecting bolt diameter in the U-shaped bi-side and at a face down bonding nut is arranged, and described nut and described hole coaxial line connect.Need connect with the base of bolt serial connection in support, Rubber shock-absorbing pad and these three layers of members of base connecting plate, the base that is in innermost layer connects the slotted hole that support has vertical direction, the locking plate nut inwardly is inserted in this vertical slotted hole position, the Rubber shock-absorbing pad that is in outermost base connecting plate and mesosphere all has the slotted hole of substantially horizontal at corresponding link position place, bolt is from penetrating outside to inside, be tightened on the nut that locking plate welds, and anti-loosening structure is arranged.Connection can be adjusted according to the needs of present position and join strength with the specification of bolt and nut.

Compared with prior art, the invention has the beneficial effects as follows:

1, air-strainer is arranged on the below of inclination one side of tilting cylinder block, has made full use of idle zone, has saved the space, is provided with like this, makes motor compacter, the motor miniaturization of being more convenient for.

2, custom-designed grafting locking plate has vertical slotted hole with one deck, two-layer three layers of connector element that have horizontal slotted hole are arranged in pairs or groups mutually, has formed the convenient, flexible connectivity scenario that is easy to adjust.This scheme does not need each member attachment hole system is proposed harsh position degree requirement, part assembling interchangeability greatly improves, for the multilayer serial connection of the punching press that easily deforms with the above bolt serial connection in two places or two places, panel beating class sheet part with change particularly convenient.

3, adopt the dual rubber shock-absorbing structure that develops simultaneously up and down, the vibrations that air-strainer is suffered obtain decay, help increasing component life and reduce noise.

Embodiment

Below in conjunction with accompanying drawing embodiments of the present invention are described further.

A kind of diagonal-cylinder type motor comprises that body 1, cylinder head 3, air-strainer 4, base connect support 12 etc.Air-strainer 4 is arranged on the below of inclination one side (A side) of tilting cylinder block 2, and the outermost end C of air-strainer 4 is positioned at cylinder head B and orders the diesel engine substantially horizontal overall sizes scope that is limited.This plan of establishment has made full use of idle zone, has saved the space, makes motor compacter, more is tending towards miniaturization.

The motor connecting plate 5 of air-strainer upper end 6 is fastenedly connected with bolt 11, nut 14 with bent plate 9 lower ends, and bent plate 9 upper ends and cylinder head 3 usefulness bolts 11 are fastenedly connected, and accompany beam 7a between motor connecting plate 5 and the bent plate 9; The base connecting plate 8 of air-strainer lower end 13 and beam 7b go up corresponding connection part and have horizontal slotted hole, the corresponding connection part that base connects support 12 has vertical slotted hole, locking plate 10 is clamped in the vertical slotted hole place that base connects support 12, this locking plate has the hole that is slightly larger than bolt 11 diameters and is welded with nut 14, described nut 14 connects with described hole coaxial line, bolt 11 with base connecting plate 8, beam 7b, connected support 12 by the base of locking plate 10 clampings and be applied in together, be tightened on the nut that is welded in locking plate 10 and locking with spring washer.Beam 7a, 7b are rubber parts.
