Description

Technical Field

[0001] The utility model relates to a wheel hub, in particular to an automobile water pump wheel hub, and belongs to the technical field of automobile production. Background Art

[0002] The automobile water pump hub is an important part of the automobile water pump. It is mainly used to transfer the power of the engine to the water pump, and then drive the water pump to work. It is usually made of metal or plastic and has a raised gear or belt groove to contact with the belt or chain. Since the normal speed of the water pump is high, a higher strength hub is required;

[0003] A Chinese patent publication (publication number: CN205533399U) discloses a hub for a cooling water pump of an automobile engine. The hub for a cooling water pump of an automobile engine is an integral structure; it includes a hub shell and the hub shell is a pancake-shaped hollow structure. Four through holes are opened on the upper surface of the hub shell. The through holes are evenly spaced along a circumference concentric with the surface of the hub shell. A cylindrical opening is extended upward in the vertical direction from the center position of the upper surface of the hub shell. The circular cross section of the cylindrical opening is concentric with the surface of the hub shell. The hub shell located between the cylindrical opening and the circumference formed by the four through holes is recessed downward to form a circle of groove structure. The groove structure is concentric with the surface of the hub shell. A circle of bosses is also provided at the lower part of the cylindrical opening near the hub shell. The inner edge parts of the upper and lower openings of the cylindrical opening are both bevel structures. A circle of side bosses of equal width is also provided outside the upper opening position of the cylindrical opening, and the lower part of the side bosses does not contact the bosses.

[0004] The automobile water pump hub is installed and fixed by means of a set through hole, but it is inconvenient to seal the installation hole when installing the hub, and the installation bolts are easily corroded when exposed to the outside for a long time, which is not conducive to the subsequent removal of the bolts. Therefore, an automobile water pump hub is proposed. Utility Model Content

As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0023] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, the embodiment of the utility model provides an automobile water pump hub, including an automobile water pump wheel body 1, three first grooves 3 are opened on the left side of the automobile water pump wheel body 1 along the circumferential direction, and three second grooves 4 are opened on the right side of the automobile water pump wheel body 1, the three second grooves 4 are arranged in a one-to-one correspondence with the three first grooves 3, and the left side of the inner wall of the second groove 4 is connected to the first groove 3;

[0025] A protection component 2 is disposed inside the second groove 4 , and the protection component 2 includes a housing 201 , a push plate 202 , a round rod 203 , a spring 204 , a limit block 205 and a rubber ring 206 .

[0026] In one embodiment, a shell 201 is movably provided inside the second groove 4, a rubber ring 206 is fixedly bonded to the rear side of the shell 201, and the left side of the rubber ring 206 is movably contacted with the left side of the inner wall of the second groove 4, two circular rods 203 are fixedly installed inside the shell 201, and two push plates 202 are movably provided on the outer side of the circular rod 203, the two push plates 202 are symmetrically arranged, and the sides of the two push plates 202 away from each other are fixedly installed with limit blocks 205, the two limit blocks 205 are symmetrically arranged, and the ends of the two limit blocks 205 away from each other extend to the outside of the shell 201 respectively, and two limit slots 6 are provided on the inner wall of the second groove 4, the two limit slots 6 are symmetrically arranged, and the two limit slots 6 cooperate with the limit slots 205, and the outer sides of the two circular rods 203 are wound with springs 204, and the limit blocks 205 cooperate with the limit slots 6, so that the shell 201 and the rubber ring 206 are conveniently fixed inside the second groove 4.

[0027] In one embodiment, the diameter of the second groove 4 is greater than the diameter of the first groove 3, so as to facilitate the fixing of the mounting bolts.

[0028] In one embodiment, two first through holes 5 are formed on the upper surface of the push plate 202 , and the inner walls of the two first through holes 5 are in movable contact with the outer sides of the two circular rods 203 , so that the push plate 202 slides on the outer sides of the circular rods 203 through the first through holes 5 .

[0029] In one embodiment, two second through holes 7 are opened on the inner wall of the shell 201, and the two second through holes 7 are symmetrically arranged. The inner walls of the second through holes 7 are in active contact with the outer side of the limiting block 205, and the limiting block 205 is extended to the outer side of the shell 201 through the opened second through holes 7.
