Abstract
The utility model discloses an integral type multifunctional cam shaft, comprising a speed adjusting flyweight bracket, a cam shaft, a speed adjusting push disc, a speed adjusting flyweight and a cam shaft timing gear. The integral type multifunctional cam shaft is characterized in that: the cam shaft timing gear is connected with the cam shaft in an interference fit manner; the speed adjusting flyweight is supported by the speed adjusting flyweight bracket; the cam shaft is provided with an air inlet cam, an air outlet cam, a high-pressure oil pump cam shaft, an oil conveying pump cam and a lubricating pump driving shaft. The integral type multifunctional cam shaft disclosed by the utility model has the beneficial effects that: 1, the assembling precision of the whole machine is improved; 2, the production efficiency is high; 3, the cost is low; and 4, the structure of the whole machine is compact.
Description
Technical field
The utility model relates to
Internal-combustion engineThe field relates in particular to
A kind of integral multifunctional camshaft that uses on the internal-combustion engine
Background technique
Valve cam of the prior art, high pressure oil pump cam are driven by same axle, and mechanical centrifugal governor is by independent gear drive.The low pressure oil transfer pump adopts electronic pump, by the 12V power source driving.Oil pump is by independent gear drive.Original technical deficiency place: 1, realize four functions simultaneously, then need amount of parts many, be unfavorable for producing in enormous quantities.2, manufacture cost is higher.3, its whole structure is compact inadequately.
Summary of the invention
The purpose of the utility model is the defective that overcomes existing technology, and a kind of multifunctional integral formula camshaft is provided, and practicality place of the utility model is that single gear drives valve cam, high pressure oil pump cam, Mechanical Centrifugal Flywheel Governor, oil transfer pump, oil pump simultaneously.
The purpose of the utility model is achieved in that described a kind of
The integral multifunctional camshaft, comprise the speed reguluting flying block support, camshaft, the speed governing push-plate, speed reguluting flying block and camshaft timing gear is characterized in that: said camshaft timing gear and camshaft adopt interference fit joint; Said speed reguluting flying block stent support speed reguluting flying block; In camshaft design intake cam, exhaust cam, high pressure oil pump cam, oil transfer pump cam and oil pump live axle are arranged.
Camshaft and camshaft timing gear adopt interference fit joint, by the crankshaft timing gear rotary driving.Camshaft design has two intake cams, two exhaust cams, two high pressure oil pump cams, an oil transfer pump cam, an oil pump live axle, and while driving device formula centrifugal speed governor.
The beneficial effect of the utility model is: 1, final assembly precision improves.2, manufacturing efficiency is high.3, cost is low.4, compact integral structure.
Description of drawings
Fig. 1 is the overall structure schematic representation of the utility model.
Fig. 2 is the right elevation of Fig. 1.
Fig. 3 is the left view of Fig. 1.
Among the figure: 1 is the speed reguluting flying block support, and 2 is camshaft, and 3 are the speed governing push-plate, and 4 is speed reguluting flying block, and 5 is camshaft timing gear, and 6 is intake cam, and 7 is exhaust cam, and 8 is the high pressure oil pump cam, and 9 is the oil transfer pump cam, and 10 is the oil pump live axle.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further elaboration:
Like Fig. 1, Fig. 2, shown in Figure 3; The said a kind of integral multifunctional camshaft of the utility model comprises speed reguluting flying block support 1, camshaft 2; Speed governing push-plate 3; Speed reguluting flying block 4 and camshaft timing gear 5 is characterized in that: said camshaft timing gear 5 adopts interference fit joint with camshaft 2, the drive cam shaft rotation.Said speed reguluting flying block support 1 supports speed reguluting flying block 4, camshaft 2 rotations, and speed reguluting flying block 4 produces centrifugal force pulls speed governing push-plate 3 and slides, and speed governing push-plate 3 bears speed reguluting flying block 4 centrifugal force, and produces axial displacement, promotes shift fork (this working principle is an existing technology).Camshaft 2 is designed with two intake cams 6, two exhaust cams 7, two high pressure oil pump cams 8, oil transfer pump cam 9, an oil pump live axle 10, and driving device formula centrifugal speed governor simultaneously.Thereby can drive valve tappet, high-pressure injection pump, low-pressure plunger formula oil transfer pump, the rotor-type oil pump of 290F diesel engine.
