Description

Brake assembly before two motorcycle types in back

Technical Field

The utility model relates to a brake assembly, in particular to a rear double-tire vehicle type front brake assembly.

Background

Light passenger car, its basic function of multi-functional commercial car is used for carrying the passenger and uses, in order to alleviate the pressure that the truck caused the road surface, part automobile factory with light passenger car, multi-functional commercial car changes the freight transportation version into and is used for carrying cargo and commodity circulation delivery, it promotes for whole car load to change the version of carrying cargo into later, original front wheel and rear wheel are single tire, in order to improve the load, need more change into double tire, for matching double tire offset grow, the wheel base is guaranteed unchangeable to the extension that the terminal surface of wheel hub installation tire need correspond, the wheel base unit need be redeveloped in conventional design, not only waste time and energy, and the cost is improved.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problems, an object of the present invention is to provide a rear two-wheel vehicle type front brake assembly.

In order to achieve the purpose, the technical scheme of the utility model is as follows: the utility model provides a stopper assembly before back double tire motorcycle type, including wheel hub unit and the switching dish that has the brake disc, the medial surface center of wheel hub unit is provided with bellied location ring, a plurality of hexagon socket head cap screw holes of evenly having arranged all around of location ring, switching dish main part is the tubular structure, switching dish one end terminal surface is provided with and is used for the location retaining ring of cover on the ring, switching dish other end terminal surface is provided with inside sunken recess, it has the hexagon bolt of twisting in hexagon socket head cap screw hole to run through in the recess, the periphery of switching dish is provided with protruding tire retaining ring in the body, tire retaining ring runs through the wheel hub bolt that has a plurality of evenly arranged.

Furthermore, the diameter of the inner end edge of the tire retainer ring is larger than that of the outer end edge of the tire retainer ring, so that a retaining platform with a radian is formed.

Furthermore, a ball pull rod is fixed on one side of the outer end of the hub unit through a ball seat.

Furthermore, a rubber dust cover is sleeved on the ball pull rod movable opening at the ball seat.

The utility model aims at matching tires with different offset distances for light passenger cars and multifunctional commercial vehicles, so that the rear axle can use single tires and can also be matched with double tires. The processing method is simple, only a plurality of threaded holes are needed to be added on the original hub for assembling the adapter plate, the adapter plate is assembled with the original hub through the hexagon bolts to achieve the purpose of matching the large-offset tire, the adapter plate is not assembled when a single tire is matched, the hub unit is provided with the hub bolts, and the tire is directly assembled; when the double tires are matched, the adapter plate is assembled, the adapter plate is provided with a hub bolt, the hub unit is not provided with a hub bolt, and the adapter plate is provided with a hub bolt.

Through the arrangement, the utility model meets the structural change of the same vehicle type in different use environments, improves the universality of parts, and has low development cost and short development period. The other performances of the product such as load and running are not changed, the product expansibility is good, and the product can be matched with tires of various types and specifications through the adjustment of the adapter plate.

Drawings

The present invention will now be further described with reference to the accompanying drawings.

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural diagram of the present invention with the adapter removed.

Detailed Description

As shown in the figure 1-2, a rear double-tire vehicle type front brake assembly comprises a hub unit 1 with a brake disc and an adapter disc 2, wherein a ball pull rod 11 is fixed on one side of the outer end of the hub unit 1 through a ball seat 10, a rubber dust cover 12 is sleeved on a movable opening of the ball pull rod 11 at the ball seat 10, a raised positioning ring 3 is arranged at the center of the inner side surface of the hub unit 1, a plurality of inner hexagonal threaded holes are uniformly distributed around the positioning ring 3, the adapter disc 2 is of a cylindrical structure, a positioning retainer ring 4 used for being sleeved on the ring 3 is arranged on the end surface of one end of the adapter disc 2, an inward recessed groove 5 is arranged on the end surface of the other end of the adapter disc 2, hexagonal bolts 6 screwed in the inner hexagonal threaded holes penetrate through the groove 5, a tire retainer ring 7 raised from the body is arranged on the periphery of the adapter disc 2, a plurality of hub bolts 8 uniformly distributed penetrate through the tire retainer ring 7, the inner end edge diameter of the tire retainer ring 7 is larger than the outer end, and a retaining platform 9 with radian is formed.
