Abstract
The invention discloses a motor vehicle braking device and particularly relates to a brake drum. The brake drum is an important vehicle part matched with a vehicle brake pad so as to realize braking on a heavy vehicle. When the vehicle is braked frequently under a load condition, a large amount of heat can be generated through high-pressure friction between the brake pad and the brake drum, and generally, a driver adopts a cold water cooling manner to reduce the temperature of a brake system, so that the brake drum can be cracked or exploded due to expansion caused by heat and contraction caused by cold generally, and in severe cases, traffic accidents can be caused, and the safety of life and property is endangered. In order to solve the problem of uniform radiation of the brake drum, the invention provides a brake device which can efficiently and uniformly radiate heat. An annular groove and a heat radiation circulation channel are respectively arranged on an inner surface of a brake drum body or an outer surface of an inner bush, and a radial air inlet through hole is arranged in the annular groove, so that the heat can be effectively radiated uniformly, the normal use of the brake drum is ensured, and the safety of life and property of people is further ensured.
Description
Technical field
The present invention relates to a kind of braking device for motor vehicle, particularly relate to a kind of brake hub.
Background technique
Thereby brake hub is a kind of important automobile component of realizing heavy-duty automobile brake that cooperates with automobile brake sheet, and heavy-duty car is because quality is larger, and inertia is also larger, so also very high to the requirement of its brake member.When automobile under loading condition during frequently braking, high pressure friction between brake block and the brake hub can produce a large amount of heat, the brake hub temperature is raise suddenly, the sensitivity that causes brake system, the driver reduces the brake hub temperature with the mode of cold water cast usually, easily like this produce the phenomenon of expanding with heat and contract with cold because of temperature shock, cause brake hub to produce slight crack, produce potential safety hazard, can cause brake failure when serious, lead to traffic accident, most patent of existing application is such as Chinese patent: 200820061991.4; 200720008859.2; All be that intensity and the friction problem that liner solves brake hub installed in employing additional, but also can produce the problems such as bad, mounting or dismounting complexity of dispelling the heat simultaneously, increased cost of production.
Summary of the invention
Goal of the invention of the present invention: be to overcome the defective that exists in the prior art, solved the heat dissipation problem of brake hub a large amount of heat of generation after rubbing with the brake block high pressure.
Technological scheme of the present invention is:
A kind of brake hub, comprise the brake hub body, one end inboard of described brake hub body is provided with annular plate, evenly be provided with fixed hole on the circumference of annular plate, the internal surface of described brake hub body is provided with circular groove and heat radiation circulation canal, offers at least one radially air intake through hole in circular groove;
The material of brake hub body is casting carbon steel or cast low alloy steel, and radially the air intake through hole is 3～6;
Install the hollow cylindrical inner ring bushing with an expansion joint in the brake hub body additional, the material of inner ring bushing is gray cast iron or wear-resisting alloy steel, and be bolted on brake hub body inner ring, the outer surface of hollow cylindrical inner ring bushing is evenly equipped with many radiating grooves along generatrix direction, and radiating groove and brake hub body internal surface circular groove intersection all offer the air intake through hole;
The outer surface of brake hub inner ring bushing is provided with circular groove and heat radiation circulation canal, in inner ring bushing circular groove and radiating groove intersection, offers the ventilation through hole;
Brake hub body and liner adopt Spielpassung to install.
The invention has the beneficial effects as follows:
Brake hub of the present invention is simple in structure, easy processing, and cost is low, and is effective, easily implements;
The present invention has realized the even quick heat radiating of brake hub; In brake hub, install the characteristics that overcome the brake hub weak strength behind the neck bush additional, increased the bulk strength of brake hub, also possess good heat dispersion simultaneously;
Offer circular groove and heat radiation circulation canal in brake hub body inboard, and be provided with at least one air intake through hole, can solve the heat dissipation problem after brake hub is subjected to the high pressure friction, so that can not weaken braking effect because of excess Temperature in the brake hub;
The hollow cylindrical inner ring bushing with an expansion joint has been installed in the present invention additional, the material of inner ring bushing is gray cast iron or wear-resisting alloy steel, and neck bush and brake hub body are bolted, the compound brake hub that forms like this, solved original brake hub easily produces slight crack or explosion because expanding with heat and contract with cold technical problem, mounting or dismounting with bolts are convenient, easily change and regular maintenance;
The present invention is provided with many radiating grooves at brake hub internal surface, hollow cylindrical inner ring bushing outer surface, and radiating groove and brake hub body internal surface and inner ring bushing outer surface circular groove intersection, all offer the air intake through hole, good like this solution the ventilation and heat problem after the friction of brake hub and brake block, heat can in time be discharged uniformly, the cold wind that guarantees advances, and the reciprocation cycle that hot blast goes out makes brake system keep temperature constant.
