Abstract
The utility model relates to the structure of an exhaust camshaft of a diesel engine for vehicles. The front end of the camshaft is provided with a chain wheel assembling journal. A flat neck for positioning a stop point on the exhaust camshaft is arranged near the front end of the shaft journal of the camshaft, and a thrust stopping boss and a positioning pin hole which are used for installation of a phase signal disc of the camshaft are arranged near the rear end of the shaft journal of the camshaft. A rectangular vacuum pump driving slot is arranged at end of the shaft journal which is arranged at the rear end of the camshaft. The chain wheel assembling journal of the camshaft is fixedly connected with a chain wheel in a no-key mode. The exhaust camshaft of the utility model achieves the effective driving of the exhaust camshaft and a vacuum pump and can easily and accurately determine the position of the stop point on the exhaust camshaft while guaranteeing reliable connection and positioning of the signal disc. In the operating process, the friction loss of the diesel engine is reduced and the number of the parts is reduced, so that the utility model has the advantages of low noise, integrated function and compact structure and is suitable for the diesel engine with four valves butting against the camshaft while the diesel engine is electrically controlled and has compact structure as required.
Description
Technical field
The utility model relates to diesel engine for automobile, particularly a kind of exhaust cam shaft structure of diesel engine for automobile.
Background technique
The exhaust cam shaft of existing diesel engine for automobile, major function need satisfy the transmission of movement from bent axle, the opening and closing of control valve, therefore need accurate phase angle, along with the development need of four valve electronic controlled diesels, the function of camshaft is had higher requirement, as increasing the transmission of cam phase signal, drive requirements such as vacuum pump, but existing camshaft can't meet the demands.
Summary of the invention
The utility model provides a kind of exhaust cam shaft structure of diesel engine for automobile, is characterised in that: the camshaft front end has sprocket wheel assembling axle journal; Camshaft has the exhaust cam shaft top dead center position to locate flat side near on the axle journal of front end; Camshaft is near there being thrust boss and the positioning pin hole that the camshaft phase signal panel are installed on the axle journal of rear end, the axle journal end of camshaft rear end has the rectangular vacuum pump to drive slot; Described camshaft sprocket assembling axle journal and sprocket wheel adopt no key mode to be fastenedly connected.
The exhaust cam shaft that the utility model provides has been realized effective transmission of exhaust cam shaft, vacuum pump, can the simple and easy position of determining exhaust cam shaft top dead center and cam phase signal teeth exactly, guarantee reliable connection and the location of signal panel.In use reduced the frictional loss of diesel engine, reduced number of spare parts, made that diesel engine noise is low, function is integrated, compact structure is applicable to four valve overhead camshaft electronic controlled diesels of claimed structure compactness.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a leading portion schematic perspective view of the present utility model.
Fig. 3 is the sectional drawing of Fig. 2.
Embodiment: reach embodiment in conjunction with the accompanying drawings and describe.
As shown in the figure, be positioned near the front end axle journal position on the camshaft and be shaped on top dead center position and locate flat side 5,
In use, top dead center position locatees flat side 5 and a positioning and clamping instrument is used, and can determine simply that accurately exhaust cam shaft is in top dead center position.
Be positioned on the camshaft near the axle journal in rear end thrust boss 3 and the positioning pin hole 2 that the camshaft phase signal panel are installed arranged, thrust boss 3 has limited moving axially of signal panel and has guaranteed axial location dimension, positioning pin hole 2 has guaranteed the radially angle of swing of camshaft phase signal teeth, accurately the angle of the relative exhaust cam shaft top dead center of framing signal tooth.
The axle journal end of camshaft rear end has rectangular vacuum pump and drives slot 1, cooperates with the folk prescription piece of vacuum pump axle head, is used to drive vacuum pump, makes vacuum pump be arranged in the cylinder cap rear end and reduces to take up room, and has also simplified the layout of accessory drive system.
The utility model is the overhead type exhaust cam shaft, and the sprocket wheel assembling axle journal 4 and the sprocket wheel of camshaft front end adopt no key mode to be fastenedly connected, and can guarantee that connection and driving are reliable, reduce number of spare parts.
Claims (2)
