Description
Technical Field
The utility model mainly relates to the field of automobile parts, in particular to an automobile crankshaft weight reduction signal panel.
Background
The crankshaft position sensor is usually installed at the front end of the crankshaft (at the belt pulley) and the rear end of the crankshaft close to the large flywheel or in the middle of the crankshaft, and early vehicle models are also installed in a distributor and are one of the most important sensors in the control system. An automobile crankshaft signal panel is an important component of a crankshaft position sensor and is used for detecting the rotation angle of a crankshaft and the rotation speed of an engine.
The weight of present car bent axle signal panel product is generally great, and fastening force is not strong, and assembly strength is lower.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides the weight-reducing signal panel of the automobile crankshaft, which has lighter overall weight and meets the light-weight design requirement of the automobile; and the fastening force of this product is stronger, and use strength is higher, and life is longer.
In order to achieve the purpose, the utility model is realized by the following technical scheme:
the utility model provides an automobile crankshaft subtracts heavy signal disc, includes the disk body, the disk body center sets up the mounting hole, set up a plurality of teeth on the disk body outer wall, it evenly sets up a plurality of waist type lightening holes to be the circumference on the disk body, it evenly sets up a plurality of bolt holes to be the circumference on the disk body, the bolt hole is unequal with the circumference distribution diameter in waist type lightening hole.
The bolt holes are inclined plane bolt holes.
The bolt holes and the waist-shaped lightening holes are arranged in a staggered mode.
Reinforcing ribs are arranged in the waist-shaped lightening holes, and the thickness of each reinforcing rib is smaller than that of the disc body, so that steps are formed in the lightening holes.
The whole bottom surface of the tray body is sunken, so that the thickness of the edge of the tray body is larger than that of the central position.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model carries out weight reduction design on the basis of the existing crankshaft signal panel, greatly reduces the whole weight of the crankshaft signal panel through the waist-shaped weight reduction holes, and the waist-shaped weight reduction holes can also furthest ensure the strength of the crankshaft signal panel, eliminate residual stress and improve the assembly strength of the crankshaft signal panel.
The bolt hole of this structure is as the mounting hole, and it adopts the design on inclined plane, can make bolt and mounting hole in close contact with to increase the area of contact between bolt and the bolt hole, increase the mechanical strength after its installation, improve the result of use of bent axle signal panel.
Drawings
FIG. 1 is a schematic structural diagram of the present invention from a front perspective;
FIG. 2 is a schematic view of the reverse viewing angle configuration of the present invention;
reference numerals shown in the drawings: 1. a tray body; 2. mounting holes; 3. teeth; 4. a waist-shaped lightening hole; 5. bolt holes; 41. And (5) reinforcing ribs.
Detailed Description
The utility model is further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.
As shown in fig. 1-2, the weight reduction signal panel for the automobile crankshaft comprises a panel body 1, wherein a mounting hole 2 is machined in the center of the panel body 1, the mounting hole 2 serves as a positioning hole, and the positioning and mounting of the signal panel are completed by sleeving the mounting hole 2 at the front end and the rear end of the crankshaft. A plurality of teeth 3 are processed on the outer wall of the disc body 1, one end of each tooth 3 is in a discontinuous state, and the positioning function of the crankshaft signal disc is realized through the positions of the missing teeth. A plurality of waist type lightening holes 4 are evenly seted up to the circumference on the disk body 1, and waist type lightening hole can furthest's realization bent axle signal disc subtract heavy, eliminates disk body 1's residual stress simultaneously, ensures bent axle signal disc's bulk strength. Preferably, 3 waist-shaped lightening holes 4 are formed. A plurality of bolt holes 5 are uniformly formed in the disc body 1 in the circumferential direction, and the circumferential distribution diameters of the bolt holes 5 and the waist-shaped lightening holes 4 are not equal. Preferably, the circumferential distribution diameter of the bolt holes 5 is smaller than that of the kidney-shaped lightening holes 4, and the bolt holes 5 and the kidney-shaped lightening holes 4 are arranged in a staggered mode. Through the staggered arrangement of the bolt holes 5 and the waist-shaped lightening holes 4, the overall mechanical strength of the tray body 1 is ensured, the weak part of the tray body 1 caused by the uneven arrangement of the bolt holes 5 and the waist-shaped lightening holes 4 is avoided, and the structural distribution of the tray body 1 is more reasonable.
Specifically, the bolt hole 5 is an inclined plane bolt hole. The inclined plane bolt hole cooperatees with the inclined plane bolt, and after assembling, the inclined plane bolt contacts with the bolt hole inclined plane, multiplicable frictional force between the two to increase the assembly strength of bent axle signal panel.
Specifically, reinforcing ribs 41 are arranged in the waist-shaped lightening holes 4, and the thickness of each reinforcing rib 41 is smaller than that of the disc body 1, so that steps are formed in the lightening holes 4. Through the mode that the level subtracts heavy for the setting on a large scale of waist type lightening hole 4 can not lead to the fact too big weakening to the bulk strength of bent axle signal dish, has compensatied through strengthening rib 41 because the mechanical strength that the lightening hole caused lacks, has realized not only alleviateing disk body 1 weight but also does not influence its mechanical strength's effect.
Specifically, the bottom surface of the tray body 1 is integrally recessed, so that the thickness of the edge of the tray body 1 is larger than that of the center. The bottom surface of the tray body 1 is sunken to form an integral weight reduction design, so that the light weight design of the tray body 1 can be realized to the maximum extent. Through the removal of even whole material, make 1 whole weight of disk body distribute evenly, structural design is reasonable, satisfies the lightweight design requirement of vehicle.
