Abstract
The utility model discloses a flexible axle core for odometer, flexible axle core include main shaft wire rope, and first layer wire rope levogyration direction is twined side by side on main shaft wire rope, and second floor wire rope dextrorotation direction is twined side by side on first layer wire rope, and third layer wire rope levogyration direction is twined side by side on second floor wire rope, and fourth layer wire rope dextrorotation direction is twined side by side on third layer wire rope, main shaft wire rope's size is diameter 4mm, first layer wire rope comprises the wire rope that four diameter sizes are 3.55mm, second floor wire rope comprises the wire rope that four diameter sizes are 3.55mm, the third layer wire rope comprise the wire rope that seven diameter sizes are 3.55mm, the fourth layer wire rope comprise the wire rope that seven diameter sizes are 3.55mm. The utility model discloses wire rope diameter size is moderate, and its surface is through black thermal treatment, adjacent revolving between two -layer to on the contrary, fine extension the life of flexible axle core, difficult fracture.
Description
Technical field
The utility model relates to flexible axle field, relates in particular to a kind of flexible shaft core for odometer.
Background technique
The axle of motor car engine passes to gearbox power, and the velocity ratio from the output shaft of gearbox to wheel is constant.The output shaft of gearbox is equipped with one " flexible axle ", one goes in the odometer in face of driver.So-called " flexible axle " is exactly the volute having wire-core as the bracing wire of bicycle cable brake, and have lubricant oil between tube wall and inner core, outer tube is fixed and inner core can rotate, and the rotating speed of this inner core and the rotating speed of wheel have constant proportionate relationship.Flexible axle leads to speedometer, and pointer can be indicated the travelling speed of car.Simultaneously, rotating soft axle also passes on the roller counter in the middle of speedometer through worm and gear, mileage number representated by the revolution of wheel has been added up to get off, drive because the speed of a motor vehicle and mileage are all the spinning movements transmitted by same flexible axle, so these two tables together, the former indicates with pointer, and the latter is added up by roller counter.
Although above-mentioned flexible axle has flexible axle pipe to protect flexible shaft core, make flexible shaft core not by external interference and damage, still there is the phenomenon of flexible shaft core easy-rupturing.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of flexible shaft core for odometer, to overcome the defect that there is fracture in prior art for the flexible shaft core of odometer.
For solving the problems of the technologies described above, flexible shaft core for odometer of the present utility model, described flexible shaft core comprises main shaft wire rope, described first layer wire rope left hand direction wound side by side is on described main shaft wire rope, second layer wire rope clockwise direction wound side by side is on described first layer wire rope, third layer wire rope left hand direction wound side by side is on described second layer wire rope, and the 4th layer of wire rope clockwise direction wound side by side is on described third layer wire rope; The size of described main shaft wire rope is diameter 4mm; The wire rope that described first layer wire rope is 3.55mm by four diameter is formed; The wire rope that described second layer wire rope is 3.55mm by four diameter is formed; The wire rope that described third layer wire rope is 3.55mm by seven diameter is formed; The wire rope that described 4th layer of wire rope is 3.55mm by seven diameter is formed.
Wherein, described main shaft wire rope, first layer wire rope, second layer wire rope, third layer wire rope and the 4th layer of wire rope are through black fever process.
Compared with prior art, the beneficial effects of the utility model are that wirerope diameter is of moderate size, and its surface is through black fever process, and surface cleaning is smooth, and between adjacent two layers, rotation direction is contrary, well extends the working life of flexible shaft core, not easy-rupturing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model for the flexible shaft core of odometer.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
The flexible axle of speedometer is direct transferring rotational motion and torque, and flexible axle is made up of flexible shaft core, flexible axle pipe and joint etc.Flexible shaft core for odometer of the present utility model as shown in Figure 1, described flexible shaft core 1 comprises main shaft wire rope 2, described first layer wire rope 3 left hand direction wound side by side is on described main shaft wire rope 2, second layer wire rope 4 clockwise direction wound side by side is on described first layer wire rope, third layer wire rope 5 left hand direction wound side by side is on described second layer wire rope, and the 4th layer of wire rope 6 clockwise direction wound side by side is on described third layer wire rope; The size of described main shaft wire rope 2 is diameter 4mm; The wire rope that described first layer wire rope 3 is 3.55mm by four diameter is formed; The wire rope that described second layer wire rope 4 is 3.55mm by four diameter is formed; The wire rope that described third layer wire rope 5 is 3.55mm by seven diameter is formed; The wire rope that described 4th layer of wire rope 6 is 3.55mm by seven diameter is formed.
Every root wire rope of described main shaft wire rope 2, first layer wire rope 3, second layer wire rope 4, third layer wire rope 5 and the 4th layer of wire rope 6 is all through black fever process.Black fever process, also claims blackening process, and (Treatment of Metal Surface) some places are called process of turning blue, and just allows material surface produce layer of oxide layer, because temperature is not high in process, generally can not be out of shape.According to the difference of materials and technique, result is black or black-and-blue, so gain the name.
Wirerope diameter of the present utility model is of moderate size, and its surface is through black fever process, and surface cleaning is smooth, and between adjacent two layers, rotation direction is contrary, can realize positive reaction torque >=1.76NM, well extend the working life of flexible shaft core, not easy-rupturing.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
