Abstract

The utility model discloses a drifting ring which comprises a circular body (1), wherein a memory rubber ring (2) is arranged on the inner surface of the body (1); the inner diameter of the memory rubber ring (2) is smaller than the outer diameter of an automobile tire. The drifting ring can be combined tightly with the tire with large adhesion force; the circular body at the outer part can be adhered to the memory rubber ring after losing efficacy and being fractured, so that the phenomenon that the outer ring bursts and splashes to harm people is avoided; the drifting ring is high in drifting performance, and long in service life.

Description

Drift rings

Technical field

The utility model relates to a kind of auxiliary device of automobile drift.

Background technology

Control automobile for allowing people rest in when sideslip or brake failure occur automobile, offer special course about the drift skill.In above-mentioned training course, drifting state careful being implemented under controlling as far as possible.Usually allow people learn to control in the outer setting drift rings of tire and be used for reaching drifting state.Drift rings has special top layer usually, and when under wet and slippery state, this top layer can produce the friction force more smaller than rubber for tire at common road surface on such as pitch or cement concrete.

In order to improve the safety of training, require the adhesive ability between drift rings and tire large as far as possible,, so that the inner ring of drift rings is tightly embraced tire, avoid producing side-to-side movement between drift rings and tire.Disclose a kind of drift rings for addressing this problem US2010012246A1, by unique rough structure is set at the drift rings inside face, and in the side of drift rings, flange has been set, to improve safety.But in this structure, the adhesive ability between drift rings and tire is still less, and side flanges only can play salvage, can not tackle the problem at its root.And for tire, even the tire of same specifications and models, in the situation that the different decorative patterns of different manufacturers, different drainage channel, its actual size is devious, thereby causes the drift rings must be special for the specific tires that particular vendors is produced.On the other hand, in training process, drift rings itself may produce explosion, causes extra potential safety hazard.Obviously, because there is larger potential safety hazard in drift rings of the prior art, the driving teaching that the speed that therefore can only be applied to is lower, be difficult to the higher driving recreation experience of the speed that is applied to.

Therefore those skilled in the art are devoted to develop the large drift rings of adhesive ability between a kind of and tire.

The utility model content

Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide the large drift rings of adhesive ability between a kind of and tire.

For achieving the above object, the utility model provides a kind of drift rings, comprises annular body, and the inside face of described body is provided with the memory rubber ring; The internal diameter of described memory rubber ring is less than the external diameter of motor tire.

Better, described memory rubber ring and described body are structure as a whole.

Better, the thickness of described memory rubber ring is 0.8mm.

Better, described body is made by PVC or polyurethane.

For increasing the intensity of drift rings, Reducing distortion, be provided with reinforce in described body.

For ease of memory rubber ring and the body structure that is connected as a single entity, the faying face of described body and described memory rubber ring is toothed surface

For preventing the relative drift rings generation of tire axial motion, the one or both sides of described body have been wholely set flange.

Can not block the larger friction force of formation because of extending edge thin and road surface on its periphery for the assurance drift rings, the external margin of described body is provided with chamfering.

Better, described chamfering is 30 °-60 °.

Better, described chamfering is 45 °.

The beneficial effects of the utility model are: the utility model can make tire be combined with drift rings closely, adhesive ability is large, and during annular body failure fracture that can be externally, it is attached on the memory rubber ring, thereby prevent that outer shroud explosion sputter from hurting sb.'s feelings, and this drift rings drift performance is good, long service life.On the other hand, for the tire of formed objects, drift rings can adapt to the small differences such as different decorative patterns, scale error, drainage channel structure.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

Embodiment 1: as depicted in figs. 1 and 2, a kind of drift rings, comprise the body 1 of ring-type, and the inside face of body 1 has been wholely set memory rubber ring 2.Body 1 is toothed surface with the faying face of memory rubber ring 2.

Under state of nature, the internal diameter of memory rubber ring 2 is less than the external diameter of the motor tire of specific model.The thickness of memory rubber ring 2 is 0.8mm.

Memory rubber is the rubber with memory function, itself is prior art, as patent 201210271414 disclosed rubber etc.

Body can be made by PVC or polyurethane, and its inside can arrange steel wire reinforcement thing 3.

The external margin of body 1 is provided with the chamfering 6 of 45 °.

Drift rings adopts following methods to be worth:, with 1 clamping of outer ring body and High Rotation Speed, then the liquid memory rubber of high temperature is injected in the inside face of body 1, after memory rubber is cooling, just only is attached to the inwall of body 1, with body 1, be integrally formed structure.Memory rubber is attached to another material surface, and this itself is prior art.

Therefore, even outer ring body cracking, each breaking portion also will tightly be attached on inner ring memory rubber ring, thereby improve safety.Obviously, this does not need the inside face of outer ring is deliberately carried out the complicated processing of given shape, only needs it to meet memory rubber and can adhere on it and get final product.

As shown in Figure 2, when drift rings is installed, it is sleeved on the motor tire of unaerated state, then tire is inflated.In this course, the protruding pattern of tire 4 is entered in memory rubber, simultaneously, memory rubber also is squeezed in groove 5 between tire tread, therefore forming vacuum seamless between motor tire and drift rings is connected, adhesive ability between greatly having improved both,, even there is certain error in the own manufacturing dimension of tire or drift rings, produce larger adhesive ability between also not hindering both.

Because the adhesive ability between tire and drift rings improves greatly, therefore drift rings is applied to drive teaching, safety improves greatly.And the drift that the speed that drift rings can be applied to is higher is driven and is experienced, thereby improves drive recreational.

Embodiment 2: as shown in Figure 3, the structure of the present embodiment is substantially the same manner as Example 1, and difference is, a side of body 1 has been wholely set flange 1a, and chamfering 6 is 30 °, and reinforce 3 is nylon wire, and body 1 is disc with the faying face of memory rubber ring 2.

Other structures and the principle of work of the present embodiment are identical with embodiment 1.

Embodiment 3: as shown in Figure 4, the structure of the present embodiment is substantially the same manner as Example 1, and difference is, the both sides of body 1 all are provided with flange 1a, and reinforce 3 is knitting, and body 1 is disc with the faying face of memory rubber ring 2.

More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all technical personnels are in the art complied with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection domain by claims.
