Abstract
The utility model discloses a cam shaft bearing of an engine, which comprises a bearing cover and a bearing seat, wherein the bearing cover and the bearing seat are positioned and connected by a positioning pin sleeve. With the cam shaft bearing of the engine, the length of a cylinder cover is shortened; electromagnetic valves are distributed in the middle of a cam shaft bearing cover so as to control the width of the cylinder cover; and an oil path in the bearing splits flow by orifices, so that engine oil amount and oil pressure are distributed reasonably by a hydraulic tappet, the oil pumping amount of an oil pump is reduced and the mechanical loss is reduced.
Description
Technical field
The utility model belongs to the vehicular engine technical field, and specifically, the utility model relates to a kind of motor assembling formula camshaft bearing.
Background technique
At present, the camshaft bearing that automobile engine cylinder head uses is generally all given and is dodged between clearancen, so that cylinder bolt is installed, the space of dodging has increased the length of engine cylinder cover.Adopt the motor of VVT (Variable Valve Time) technology, its solenoid valve is arranged on the cylinder cap or first shaft-cup, and generally is to arrange toward the cylinder cap left and right sides, has increased the width of cylinder cap.The oil circuit that leads to hydraulic tappet is arranged, generally be arranged on the cylinder cap, regulate oil mass with the throttling bolt and distribute, or do not have the throttling measure at all, cause the oil mass that releases by hydraulic tappet excessive, increase the work load of oil pump, the oil pump mechanical loss is bigger; The oil circuit that leads to VVT solenoid valve, phase discriminator is arranged, be arranged on the cylinder cap or on the bearing cap, do not have one-way valve to prevent that oil from refluxing, have the risk of fluctuation of phase discriminator operating oil pressure or operational failure.
The model utility content
The technical problems to be solved in the utility model provides a kind of engine cam axle bearing, with the length and the width of reasonable control engine cylinder cover, and oil level and oil pressure that reasonable distribution cylinder covers.
To achieve these goals, the technical solution adopted in the utility model is: a kind of engine cam axle bearing, comprise bearing cap and bearing support, and described bearing cap and bearing support are located by connecting by set pin sleeve.
Described bearing cap middle part be provided with the VVT parts in the adaptive solenoid valve mounting hole of solenoid valve.
In the oil circuit of the oil duct in being communicated with described solenoid valve mounting hole and described bearing support one-way valve is installed.
Described bearing support is provided with and is communicated with the interior oil duct of described bearing support and the throttle orifice of hydraulic tappet.
Advantage of the present utility model is that the assembling camshaft bearing has shortened the length of cylinder cap; Arrange solenoid valve at the camshaft-bearing cap middle part, controlled the width of cylinder cap; Oil circuit in the bearing is shunted by throttle orifice, leads to hydraulic tappet, reasonable distribution machine oil mass and oil pressure, and the pump oil mass of reduction oil pump has reduced mechanical loss.
Description of drawings
Below the content of each width of cloth accompanying drawing expression of the utility model specification and the mark among the figure are made brief description:
Fig. 1 is the utility model camshaft bearing structure for engine schematic representation;

Mark among the above-mentioned figure is: 1, bearing cap; 2, bearing support; 3, solenoid valve mounting hole; 4, set pin sleeve; 5, one-way valve; 6, steel ball; 7, throttle orifice; 8, machine oil inlet; 9, oil duct.
Embodiment
Contrast accompanying drawing below, by description to embodiment, effect and working principle, the manufacturing process of mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technological scheme had more complete, accurate and deep understanding to help those skilled in the art.
To shown in Figure 5, a kind of engine cam axle bearing comprises bearing cap 1 and bearing support 2 as Fig. 1, and described bearing cap 1 and bearing support 2 are located by connecting by set pin sleeve 4.
Adopt technique scheme, described bearing cap and bearing support are provided with positioning hole, fit together by set pin sleeve 4 location, have shortened the length of engine cylinder cover and motor integral body.
Described bearing cap 1 middle part be provided with the VVT parts in the adaptive solenoid valve mounting hole 3 of solenoid valve.Adopt technique scheme, solenoid valve mounting hole 3 is set, be used to install the VVT solenoid valve, thereby shorten the width of engine cylinder cover and motor integral body at the middle part of described bearing cap 1.
In the oil circuit of the oil duct in being communicated with described solenoid valve mounting hole 3 and described bearing support 2 one-way valve 5 is installed.Described bearing support 2 is provided with the throttle orifice 7 of the oil duct 9 that is communicated with in the described bearing support 2 and hydraulic tappet.
Adopt technique scheme, described one-way valve 5 and throttle orifice 7 play the machine oil oil mass and the effect of regulating and control oil pressure of the VVT phase discriminator of reasonable distribution supply engine hydraulic tappet.Engine cylinder-body enters the oil duct 9 in the bearing support 2 to the machine oil slave oil-in 8 of cylinder cap, this oil duct technology mouth is blocked by steel ball 6, and the machine oil in the described oil duct 9 offer motor hydraulic pressure tappet by described throttle orifice 7 on the one hand and finally release; The on the one hand more machine oil described one-way valve 5 of flowing through continues to be supplied to VVT solenoid valve and phase discriminator again, arrives the junction plane lubricate of camshaft bearing journal and bearing simultaneously.This one-way valve 5 is set stops towards the machine oil of VVT solenoid valve, phase discriminator and reflux, guarantee that the operating oil pressure of phase discriminator is normal.This throttle orifice 7 is set, reduces the oil mass and the oil pressure of access to engine hydraulic tappet, reduce the pump oil mass of oil pump, reduced mechanical loss.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technological scheme carry out; or design of the present invention and technological scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
