Description
Technical field
The utility model belongs to brake system of car component technical field, particularly relates to a kind of annular groove steel loop brake drum.
Background technique
Braking system is one of important composition system of automobile, and at present, in truck field, widely used is adopt traditional cast inblock drum brake.
In prior art, typical drum brake comprises brake drum and brake shoe composition, and brake shoe can contact with the inner side surface of brake drum.Brake drum is in rotary state in vehicle traveling process, and when needs brake, brake shoe presses under the action of the braking force on brake drum, utilizes the surface friction drag between brake drum, thus makes car deceleration or the parking of traveling, to ensure traffic safety.
When automobile heavy-load, run at high speed time, especially when lower long slope or abrupt slope, owing to needing the braking of larger braking force and continuous several times to ensure that automobile is in controllable state, brake drum inner wall temperature is sharply raised, the internal-external temperature difference of brake drum strengthens, and causes the mechanical behavior under high temperature forming brake drum material sharply to decline.Because traditional brake drum material is gray cast iron, gray cast iron has the typical characteristics that the low fragility of intensity is greatly grey cast iron, in order to reduce the negative effect that these characteristics are brought, the wall thickness of brake drum must do very thick in ensure that brake drum has higher structural strength.But the wall thickness of brake drum is larger, internal-external temperature difference during brake drum braking is larger, and the temperature difference strengthens the temperature difference stress caused and adds that the mechanical behavior under high temperature of material worsens, and often causes brake drum inwall to develop into be full of cracks by longitudinal fine fisssure, so that last brake drum cracking.Therefore, traditional cast-in-block brake drum is shorter for working life.
Model utility content
Technical problem to be solved in the utility model is: provide a kind of annular groove steel loop brake drum, to solve the technical problem that existing brake drum Safety performance is low, working life is short.
For solving the problems of the technologies described above, the technical solution of the utility model is:
Annular groove steel loop brake drum, comprises the brake drum body that cast iron materials is made, and described brake drum body is provided with stirrup assembly department, and the outer surface of described stirrup assembly department is set with some stirrups, the axis of described stirrup and the axes coincide of described brake drum body.
Improve as one, the sectional shape of described stirrup is rectangle, the sectional area being positioned at the described stirrup in neutral position is greater than the sectional area of the described stirrup being positioned at two side positions, the outer surface of described brake drum body offers some stirrup mounting grooves, and stirrup described in each all retrains and is installed in stirrup mounting groove described in.
Improve as one, the sectional shape of described stirrup is U-shaped, the sectional area being positioned at the described stirrup in neutral position is greater than the sectional area of the described stirrup being positioned at two side positions, the outer surface of described brake drum body offers some stirrup mounting grooves, and stirrup described in each all retrains and is installed in stirrup mounting groove described in.
Improve as one, the sectional shape of described stirrup is not contour U-shaped structure, and the outer surface of described brake drum body offers a stirrup mounting groove, and some described stirrups lean successively together and retrain and are installed in described stirrup mounting groove.
Improve as one, the height of described stirrup successively decreases from neutral position to both sides.
After have employed technique scheme, the beneficial effects of the utility model are:
Because annular groove steel loop brake drum comprises brake drum body, brake drum body is provided with stirrup assembly department, the outer surface of stirrup assembly department is set with some stirrups, can realize under the prerequisite reducing brake drum body thickness by the enclasping force of stirrup, improve the structural strength of brake drum body, add heat dispersion, improve mechanical property and Security, extend the working life of brake drum.
Sectional shape due to stirrup is U-shaped, can reduce the thickness of stirrup, and then alleviate the weight of stirrup under the prerequisite ensureing brake drum body structure intensity.
Outer surface due to brake drum body offers a stirrup mounting groove, some stirrups lean successively together and retrain and are installed in stirrup mounting groove, when brake drum body is by thermal quench, water can be avoided directly to contact phenomenon that brake drum body causes hot tearing and explosion, stirrup enclasping force is stronger in addition, avoid brake drum body to break the danger flown out, improve Security, and extend brake drum working life.
Sectional area due to the stirrup being positioned at neutral position is greater than the sectional area of the stirrup being positioned at two side positions, the power that brake drum body is subject to when braking can be successively decreased from neutral position to both sides, and the sectional area of stirrup successively decreases from neutral position to both sides the Security arranging and can ensure brake drum body.
