Abstract
The utility model discloses a device for improving the strength of an engine body. The device is structurally characterized in that an engine body reinforcing plate is fixed on the engine body, four or six rectangular holes are arranged at the central part of the reinforcing plate, a positioning sleeve is inlaid at the left upper corner of the reinforcing plate and is concentric with an engine oil passage in the engine body, an O-shaped rubber ring is inlaid outside the positioning sleeve, two small bolt holes are arranged on the external edge of the positioning sleeve and nine large bolt holes are arranged around the reinforcing plate. On the premise that a gantry engine body is unchanged, the strength and the rigidity of the gantry engine body can be improved and an open engine body can be changed to a closed engine body; after the reinforcing plate is fixed on the engine body and is sealed by using an oil pan, the shape of the complete engine is unchanged; the power of the engine is improved on the basis of the original engine model, the noise is reduced, the explosion pressure is improved and the emission is reduced; and the structure of the device is simple, the volume is small, the device is adaptive to the structural design of the engine and thereby the device can be widely used on the engine with the gantry engine body.
Description
Technical field
The utility model belongs to engine components, is specifically related to a kind of parts that the planer-type body improved its intensity.
Background technique
Along with the raising of domestic highway road conditions quality, the Deadweight cargo capacity of transport vehicle is increasing gradually, so the output power of motor also needs continuous increase.The raising of HP, hp/litre, the requirement of strength to motor also strengthens day by day so.Under the prerequisite that satisfies emission request and power ascension, redesigning high-intensity body can head it off, but the fund input that brings thus also is very considerable.Newly-designed high strength body need cycle of upgrading also quite long simultaneously, because will be referred to the improvement of machining production line.In addition the increase of engine body intensity, its volume also must increase, and can original vehicle assemble and just become realistic problem.The motor of planer type structure body is more at present, if can propose a kind of method that improves its intensity on the basis of original housing construction in this case, just can solve many problems, and the platform that for example matched originally just can adapt to.So proposition of the present invention, under the prerequisite of original structure, the mechanical strength that improves motor is improved its power, is that the institute of the industry asks.
Summary of the invention
The purpose of this utility model is to increase the part device of a raising motor overall mechanical strength on engine body.
Below in conjunction with accompanying drawing structural principle of the present utility model is described.The device that strengthens engine body intensity mainly comprises: body stiffening plate, setting sleeve, O type rubber ring and fixing bolt etc.Fix a body stiffening plate on engine body, the middle part of body stiffening plate is provided with 4 or 6 rectangular holes, and the upper left corner of body stiffening plate is inlaid with setting sleeve, the oil passageway concentric in setting sleeve and the engine body.O type rubber ring edge is enclosed within the setting sleeve outside, is provided with two stove bolt holes in the outer of setting sleeve, is provided with 9 king-bolt holes around the body stiffening plate.The aperture in described stove bolt hole is 7mm; The aperture in described king-bolt hole is 11mm.Its principle is to adopt a body stiffening plate that the planer-type engine body is become enclosed.On structural design: the upper left corner at the body stiffening plate is inlaid with setting sleeve, on the basis of improving the motor overall mechanical strength, the main effect of setting sleeve is that body stiffening plate and engine body are accurately located, and is passed to the path of oil pump simultaneously again as fuel filter machine oil.O type rubber ring is equipped with in setting sleeve outer ring and the contacted place of body stiffening plate, makes that machine oil is unlikely to ooze out from setting sleeve.Rectangular hole on the body stiffening plate is to rotate the space that is provided with for the engine crankshaft connecting rod.
Characteristics of the present utility model and beneficial effect are, under the situation that does not change engine body, can improve planer-type strength of machine body and rigidity, improve the power of motor on original type, reduce noise, improve pressure of explosion, reduce discharging.These parts are simple in structure, volume is little, adapt to the structural configuration on the motor, can be extensive use of on the motor of planer-type body.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
Fig. 2 is Fig. 1 part section structure diagram.
Embodiment
Below in conjunction with accompanying drawing and by embodiment structure of the present utility model is described further.The device that strengthens engine body intensity mainly is to fix a body stiffening plate 2 (Fig. 1) on engine body 1.The middle part of body stiffening plate 2 is provided with 4 or 6 rectangular holes 3.The upper left corner of body stiffening plate 2 is inlaid with setting sleeve 4, oil passageway 8 concentrics in setting sleeve 4 and the engine body 1.O type rubber ring 5 edges are enclosed within setting sleeve 4 outsides (Fig. 2), are provided with two stove bolt holes 6 in the outer of setting sleeve 4; Around body stiffening plate 2, be provided with 9 king-bolt holes 7.The aperture in stove bolt hole 6 is 7mm; The aperture in king-bolt hole 7 is 11mm.
For present embodiment, the body stiffening plate is used for the planer-type engine body.The thickness of body stiffening plate is the ironcasting of 10mm, leaves a stepped shaft through hole in the body stiffening plate upper left corner, in order to installing and locating cover and O type rubber ring.Process the circular hole of 2 7mm simultaneously at the excircle of location trepanning, the position identical at engine body is provided with tapped hole, pass 2 circular holes of sump strainer mounting hole and stiffening plate during assembling with the 6mm bolt, sump strainer and planer-type engine body are fixed.So setting sleeve has the location and is connected the effect of sump strainer to the oil pump pipeline.The several cylinder number according to motor of rectangular hole determine that present embodiment is left 4.The effect of rectangular hole is to bump with the body stiffening plate when preventing that crankshaft-and-connecting-rod from rotating to contact.The size of rectangular hole is determined according to the track of rotation radius bar and connnecting rod big end.Stiffening plate is fixed with the engine body lower end surface with the bolt (by aforementioned king-bolt hole) of M10, and whole parts and body form one, and the open type body is become enclosed body (as Fig. 1).After stiffening plate was fixed on the engine body, with the oil sump sealing, promptly whole device was all in oil sump inside, and the profile of motor complete machine does not change.
Claims (2)
