Description
Technical field
The utility model is a kind of engine cam signal transmitting apparatus.
Background technique
At present, more and more users begin to accept gas-fueled vehicles, and what take a fancy to is mainly its advantage in energy-conserving and environment-protective.Domestic have a lot of natural gas engines all to improve on existing diesel oil and petrol engine basis and design.
Camshaft location signal transmission device gathers camshaft phase signals, helps natural gas engine to judge firing time.The accurate control of the firing time of spark plug is just very important, all can cause the decline of power character, Economy and the increase of discharging too early evening excessively.
At present, the body design improvement space of natural gas engine is less, install, arrange the complicated layout in bearing rear case space, in the situation that the engine operation environment is abominable, the transmission shaft end is beated excessive, causes the gap between signal emitter and signal panel tooth to change, the collection of undesired signal sensor signal, cause the degree of accuracy of the top dead center of gas engine to reduce, affect the performance of motor.
Summary of the invention
The utility model is for the deficiencies in the prior art, a kind of engine cam signal transmitting apparatus is provided, the utility model is reasonable in design, cost is low, assembling is simple, reliability is high, optimize lubrication System Design, do not need running in bearings and realize stablizing, the function transmitted of signal exactly, the top dead center degree of accuracy that has improved motor.
The utility model is realized by following technical measures: a kind of engine cam signal transmitting apparatus, comprise timing signal housing, transmission shaft, described timing signal housing is fixed on engine cylinder-body, on described timing signal housing, signal emitter is installed, one side pressure of described transmission shaft is equipped with the camshaft pulse dish, described camshaft pulse dish is positioned at timing signal housing and coordinates with described signal emitter, the other end of described transmission shaft is installed with gear, the locking nut axially locating of described gear by coordinating with transmission shaft.
Concrete characteristics of the present utility model also have, and above-mentioned timing signal housing rear end processing oil sealing base is equipped with oil sealing in described oil sealing base, and described oil sealing is between described camshaft pulse dish and described timing signal housing.
Establish oil leab in above-mentioned transmission shaft, described oil leab is communicated with the lubricant oil of cylinder body, and two fixing shoulders are arranged in described timing signal housing, processes oil inlet hole on the fixedly shoulder of rear end, process bottom the draining hole at the fixedly shoulder of front end, the lubricant oil of described oil leab can flow back to oil sump.
6 alignment marks and 1 sync mark are arranged on above-mentioned camshaft pulse dish, and it still plays the effect of oil seal shaft.
Above-mentioned transmission shaft is supported on two interior fixing shoulders of timing signal housing.
The beneficial effects of the utility model are:
1, the load of transmission shaft transmission is little, and bearing need not be installed, and reduces noise and rate of fault.
2, the simple structure of timing shell space, easily manufacturing, easily assembling.
3, the lubrication system of optimizing, integrated oil sealing designs, and has guaranteed the reliability of camshaft location signal transmission device.
4, the both shoulders of timing housing support, and make the signal panel smooth running, have guaranteed the accuracy that signal transmits.
