Abstract
The utility model relates to a kind of packoff of Novel camshaft torque measurement web member, it is characterized in that: collector ring is fixedly connected with camshaft torque measurement web member front end, the rear end of camshaft torque measurement web member is fixedly connected with engine cam by bolt, between camshaft torque measurement web member and engine cam, be fixedly connected with camshaft sprocket, engine bonnet contacts with the needle bearing on camshaft torque measurement web member, engine bonnet and needle bearing are by siliceous sealant sealing, foil gauge on engine cam is connected with collector ring by lead-in wire, lead-in wire passes from the inner chamber of engine cam and camshaft torque measurement web member.It has solved the sealing problem of web member, and require lower to machining precision and web member and camshaft right alignment, friction force is less, by being similar to the device of needle bearing, be arranged on camshaft torque measurement web member, labyrinth sealing band can solve sealing problem, has reduced the machining precision of web member, simplifies Installation and Debugging process.
Description
Technical field
The utility model relates to a kind of packoff of Novel camshaft torque measurement web member, belongs to the VCT exploitation in engine valve actuating mechanism system development field.
Background technology
Along with the application of gasoline engine VCT, the measurement of camshaft moment of torsion is more and more important, for making measurement more accurate, should measure in complete machine fired state as far as possible.In the time that this state is measured, lead-in wire and sealing have just become key issue urgently to be resolved hurrily.Foreign technology personnel install O-ring seal on web member, O-ring seal is peripheral fixedly solves sealing problem with cover cap, the method is had relatively high expectations to web member and camshaft right alignment, machining precision is high, Installation and Debugging more complicated, and between O-ring seal and web member, friction force is larger, has affected measuring accuracy.
Summary of the invention
The purpose of this utility model is to provide a kind of packoff of Novel camshaft torque measurement web member, it has solved the sealing problem of web member, and require lower to machining precision and web member and camshaft right alignment, friction force is less, by being similar to the device of needle bearing, be arranged on camshaft torque measurement web member, labyrinth sealing band can solve sealing problem, reduce the machining precision of web member, simplified Installation and Debugging process
The technical solution of the utility model is achieved in that a kind of packoff of Novel camshaft torque measurement web member, it is characterized in that: collector ring is fixedly connected with camshaft torque measurement web member front end, the rear end of camshaft torque measurement web member is fixedly connected with engine cam by bolt, between camshaft torque measurement web member and engine cam, be fixedly connected with camshaft sprocket, engine bonnet contacts with the needle bearing on camshaft torque measurement web member, engine bonnet and needle bearing are by siliceous sealant sealing, foil gauge on engine cam is connected with collector ring by lead-in wire, lead-in wire passes from the inner chamber of engine cam and camshaft torque measurement web member.
Good effect of the present utility model is its problem that mainly solves engine cam moment of torsion overall measurement, ensures the precision of torque measurement, simplifies Installation and Debugging process, there is versatility, easily apply, can ensure the accuracy of camshaft torque measurement, for the design of VCT provides reliable foundation.
Brief description of the drawings
Fig. 1 is the assembly structure figure of utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further: as shown in Figure 1, a kind of packoff of Novel camshaft torque measurement web member, it is characterized in that: collector ring 1 is fixedly connected with camshaft torque measurement web member 2 front ends, the rear end of camshaft torque measurement web member 2 is fixedly connected with engine cam 6 by bolt 5, between camshaft torque measurement web member 2 and engine cam 6, be fixedly connected with camshaft sprocket 4, engine bonnet 3 contacts with the needle bearing 9 on camshaft torque measurement web member 2, engine bonnet 3 seals by siliceous fluid sealant 10 with needle bearing 9, foil gauge 7 on engine cam 68 is connected with collector ring 1 by going between, lead-in wire 8 passes from the inner chamber of engine cam 6 and camshaft torque measurement web member 2.
Solve sealing problem by forming labyrinth sealing band between camshaft torque measurement web member 2 and needle bearing 9, in engine bonnet 3 relevant position borings, camshaft torque measurement web member 2 and camshaft sprocket 4 are fixed on engine cam 6 by bolt 5.Needle bearing 9 is arranged on camshaft torque measurement web member 2, and needle bearing 9 is filled with siliceous fluid sealant 10 with the gap of engine bonnet 3.
On camshaft 6 axle journals, paste foil gauge 7 according to torque measuring method, the lead-in wire of foil gauge 78 is drawn by camshaft 6 inner chambers and camshaft torque measurement web member 2 inner chambers, be connected on collector ring 1, thereby strain signal is drawn.
Along with the rotation of camshaft 6, foil gauge 7 signals are transferred in several extraction systems by collector ring 1, and the inner mist of oil of cover cap 3 cannot be by forming labyrinth sealing band between camshaft torque measurement web member 2 and needle bearing 9, thereby reach sealing effectiveness.Because it is completely coaxial that camshaft torque measurement web member 2 cannot ensure with camshaft 6, so can produce and beat in rotary course, this is beated and can make up by the elasticity of the siliceous fluid sealant 10 between needle bearing 9 and engine bonnet 3.
The detailed description that the utility model uses on CA4GA1 gasoline engine:
Camshaft 6 at corresponding stickup foil gauge 7, is installed camshaft torque measurement web member 2 and needle bearing 9 with method shown in Fig. 1 according to torque measuring method, and foil gauge 7 signals 8 are connected on collector ring 1 by going between.
Final assembly, tests and image data with each operating mode, after the corresponding operating mode of engine is stable, carries out left and right data acquisition in ten seconds.
