Abstract
The utility model provides a kind of brake wheel for drum brake, and comprise the coaxial roller, roller shaft and the lining that arrange, described roller housing is located at outside roller shaft, is provided with lining between described roller and roller shaft; The external diameter of lining and the internal diameter of roller adopt interference fit, and the internal diameter of lining and the external diameter of roller shaft adopt Spielpassung, and the utility model is wear-resistant, long service life.
Description
Technical field
The utility model belongs to brake system of car technical field, particularly relates to a kind of brake wheel.
Background technique
Braking system is in order to make the external world apply certain power in some part of automobile on automobile, thus carries out a series of special arrangements of forced brake to a certain degree to it.The general work principle of braking system is, utilizes phase mutual friction between the non-rotating component be connected with vehicle body and the rotatable member be connected with wheel to the trend of the rotation or rotation that stop wheel.Common braking system is divided into drum brake system and disk braking system.In drum brake system, brake wheel is played an important role in braking system.Brake wheel, as holistic roller, because the rotation of brake camshaft causes brake camshaft and produce between brake wheel and brake shoe iron and rub in braking process, easily causes each component wear and deterioration in advance.
Model utility content
Goal of the invention of the present utility model is the narrow limitation solving above-mentioned existing brake wheel, provides a kind of anti abrasive brake wheel.
The utility model comprises the coaxial roller, roller shaft and the lining that arrange, and described roller housing is located at outside roller shaft, is provided with lining between described roller and roller shaft; The external diameter of lining and the internal diameter of roller adopt interference fit, and the internal diameter of lining and the external diameter of roller shaft adopt Spielpassung.
After adopting above structure, the utility model compared with prior art, has the following advantages:
The utility model employing roller, roller shaft and lining three parts cooperatively interact and replace traditional overall roller, in braking process, the rotation of brake camshaft drives the rotation of roller and copper bush, and roller shaft transfixion, therefore friction is concentrated between lining and roller, thus wearing and tearing can not be caused by pair roller axle.Lining is wear-resistant and be convenient to change.Therefore, for traditional brake wheel, the utility model makes increase substantially the working life of each parts.The utility model provides a kind of anti abrasive brake wheel.
As improvement, the material of described lining is copper.Employing copper bush is with low cost, has stronger wear-resisting property.
As improvement, described roller inner diameter edge is protruding, and described lining is limited between described projection.The position of the lining described in restriction, makes lining arbitrarily slide.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Shown in figure 1, roller, 2, roller shaft, 3, lining.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model comprises the coaxial roller 1, roller shaft 2 and the lining 3 that arrange as shown in Figure 1, and described roller 1 is set in outside roller shaft 2, is provided with lining 3 between described roller 1 and roller shaft 2; The external diameter of lining 3 and the internal diameter of roller 1 adopt interference fit, and the internal diameter of lining 3 and the external diameter of roller shaft 2 adopt Spielpassung.The material of described lining 3 is copper.Described roller 1 inner diameter edge is protruding, and described lining 3 is limited between described projection.
In use, the utility model is arranged in drum brake system, with brake camshaft with brake iron heel and cooperatively interact.In braking process, the rotation of brake camshaft makes brake camshaft and produces between brake wheel 1 and brake shoe iron to rub, the rotation of brake camshaft drives roller 1 to rotate, because the external diameter of the internal diameter of roller 1 and lining 3 adopts interference fit, frictional force between described roller 1 and described lining 3 is comparatively large, transmission simultaneously.And the external diameter of the internal diameter of lining 3 and roller shaft 2 adopts Spielpassung, roller shaft 2 transfixions.Because the frayed degree of described roller shaft 2 is little, long service life.
Below only just most preferred embodiment of the present utility model is described, but can not be interpreted as it is limitations on claims.The utility model is not limited only to above embodiment, and all various changes done in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
