Abstract
The utility model relates to a kind of band heat radiation slot type brake drum, it comprises brake drum body, it is characterized in that: on the braking surface of brake drum body, integrally casting has 10 equally spaced radiating grooves, described radiating groove is V-shaped skewed slot, the hypotenuse of the cross section of described skewed slot and the angle а of center line are 15 degree, the width L of skewed slot opening is 12 millimeters, and the bottom land of described skewed slot is provided with the smooth excessive circular arc with the groove face of skewed slot.The radiating groove system of the utility model braking drum surface can form airflow channel, improves heat dissipation rate, avoids temperature too high and the brake failure that causes, also can reduce high temperature and meet the quantity that water breaks, extend the working life of brake drum.
Description
Technical field
The utility model belongs to automobile brake part, is specifically related to a kind of band heat radiation slot type brake drum.
Background technique
In the drum brakes system of automobile, undertaken rubbing by the friction plate in break and brake drum and realize the braking of vehicle, the brake drum braking surface of traditional design is smooth surface, in automobile frequently brake process, the heat of brake drum not easily scatters and disappears, and temperature can raise fast, therefore a lot of vehicle is had also to be furnished with water tank, adopt the mode of " Quench " to lower the temperature to brake drum fast, such operation can cause the braking surface of brake drum to ftracture, braking failure.
Summary of the invention
The purpose of this utility model is to provide a kind of band heat radiation slot type brake drum.This brake drum is lightweight, decreases the process step of existing brake drum at heat radiation process aspect, improves production up-to-standard rate, decrease the failure mode of brake drum braking surface cracking, improve the working life of brake drum.
The technical solution adopted in the utility model: a kind of band heat radiation slot type brake drum, it comprises brake drum body 1, on the braking surface 2 of brake drum body 1, integrally casting has 10 equally spaced radiating grooves 3, described radiating groove 3 is V-shaped skewed slot, the hypotenuse of the cross section of described skewed slot and the angle а of center line are 15 degree, the width L of skewed slot opening is 12 millimeters, and the bottom land of described skewed slot is provided with the smooth excessive circular arc with the groove face of skewed slot.
The utility model compared with prior art its beneficial effect is: 1. the utility model adds braking force, makes brake sensitiveer, by it for the frequent vehicle braked, and such as bus, applicable effective amount is better; The radiating groove system of 2. braking drum surface can form airflow channel, improves heat dissipation rate, avoids temperature too high and the brake failure that causes, also can reduce high temperature and meet the quantity that water breaks, extend the working life of brake drum; 3. the utility model is owing to have employed the breaker slot system of good braking effect, brake drum weight is alleviated greatly, and due to the braking hole slot on brake drum be cast to form together with brake drum, cost of production is reduced, and meets the policy requirements of national energy-saving environmental protection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view along A-A hatching in Fig. 1;
Fig. 3 is the enlarged cross sectional views of radiating groove in Fig. 1.
Embodiment
A kind of band heat radiation slot type brake drum, as Fig. 1 and Fig. 2, it comprises brake drum body 1, on the braking surface 2 of brake drum body 1, integrally casting has 10 equally spaced radiating grooves 3, as Fig. 3, radiating groove 3 is V-shaped skewed slot, and the hypotenuse of the cross section of described skewed slot and the angle а of center line are 15 degree, the width L of skewed slot opening is 12 millimeters, and the bottom land of described skewed slot is provided with the smooth excessive circular arc with the groove face of skewed slot.Brake drum is when frequently braking, and the heat of generation directly can be discharged by the radiating groove 3 on equally distributed 10 braking surfaces 2, so reduce brake drum temperature in use, reduces the defective drum fault of the too high initiation of Yin Wendu.
