CN206968294U - A kind of mechanical elastic vehicle wheel hinge set structure with sealing-plug - Google Patents

Abstract

The utility model patent discloses a mechanical elastic wheel hinge group structure with a sealing plug, which includes several hinges; the hinges are connected by pins installed in the hinge mounting holes to form a hinge group; the two ends of the hinge group The hinge connection holes are respectively connected with the snap ring and the hub of the mechanical elastic wheel through the pin shaft; the two ends of the pin shaft are respectively provided with tapered roller bearings; the outermost end of each hinge connection hole is provided with a sealing plug . The material of the sealing plug is metal or non-metal such as rubber, plastic, etc. If it is a metal material, it needs to be installed in the hinge group with threads, and if it is a non-metal material, it is directly plugged. Due to the existence of the sealing plug, the wheel can prevent some sand and gravel from entering the bearing during driving, so as to improve the service life of the wheel hinge group.

Description

A Mechanical Elastic Wheel Hinge Group Structure with Sealing Plug

technical field

The utility model relates to a mechanical elastic wheel hinge group structure with a sealing plug, which belongs to the technical field of non-inflatable safety wheels.

Background technique

In recent years, with the increase of vehicle speed and the expansion of driving environment, the requirements for tires have become higher and higher. Traditional pneumatic tires have the following disadvantages: (1) prone to tire punctures or blowouts, and lack of safety; (2) need to maintain proper tire pressure at all times; (3) require frequent maintenance. Therefore aiming at the inherent defects in the structure of pneumatic tires, getting rid of the basic structure of traditional pneumatic tires and developing safety wheels with non-pneumatic structures has become a current trend.

At present, there is no sealing plug between the hinges of the hinge group structure of the general mechanical elastic wheel. The main problem of this bearing connection method is that the hinges often enter some sand and gravel during the driving process of the car, which causes the wear of the bearings to increase and shortens its life. .

Contents of the invention

The utility model provides a mechanically elastic wheel hinge group structure with a sealing plug, which enables the hinge group to transmit torque and buffer vibration during the rotation of the wheel, and at the same time prolongs its service life.

In order to achieve the above object, the utility model adopts the following technical solutions:

A mechanically elastic wheel hinge group structure with sealing plugs, comprising several hinges; the several hinges are connected by pins installed in the hinge mounting holes to form a hinge group; the hinge connection holes at both ends of the hinge group are respectively connected by pins The shaft is connected with the snap ring and the hub of the mechanical elastic wheel; the two ends of the pin shaft are respectively provided with tapered roller bearings; and the outermost end of each hinge connection hole is provided with a sealing plug.

Further, the number of hinges is 2 to 4.

Further, the hinge is made of metal elastic material or non-metal elastic material.

Further, the material of the sealing plug is metal, rubber, or plastic. If it is a metal material, it needs to be installed in the hinge group with threads, and if it is a non-metal material, it should be directly plugged.

The beneficial effects of the utility model are:

1. Prevent sand and gravel from entering the bearing during the running of the wheel, and improve the service life of the wheel hinge group; 2. Transfer the torque from the axle, and use its free rotation and bending characteristics to alleviate different degrees of impact from the road surface. Increase the life of the wheels while increasing the comfort of the occupants.

Detailed ways

Below in conjunction with accompanying drawing, the technical scheme of the utility model is described in further detail:

As shown in Figures 1, 2, and 3, the utility model includes several hinges, which are respectively the first hinge 3, the second hinge 4, and the third hinge 5; the hinges are formed by connecting the pin shafts 10 installed in the hinge mounting holes. Hinge group; the hinge connection holes at both ends of the hinge group are respectively connected with the snap ring 7 and the wheel hub 9 of the mechanical elastic wheel through the pin shaft 10; the two ends of the pin shaft 10 are respectively provided with tapered roller bearings 2; Sealing plugs 1 are provided at the outermost ends of the hinge holes. The number of hinges is 2 to 4. The hinge is made of metal elastic material or non-metal elastic material. The material of the sealing plug is metal or non-metallic materials such as rubber and plastic.

If the sealing plug is made of metal, it needs to be installed in the hinge group with threads; if it is made of non-metallic materials such as rubber and plastic, it should be fixed by inserting the sealing plug into the connecting hole.

The utility model is a main link part of a new type of mechanical elastic wheel, the main function is to transmit the torque from the axle, and use its free rotation and bending characteristics to alleviate the impact of different degrees from the road surface, and improve the comfort of the passengers in the car. Sex while increasing the life of the wheel.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made. Retouching should also be regarded as the scope of protection of the present utility model.
