Description
Technical field
The utility model relates to a kind of cooling unit of lorry brake drum, and particularly a kind of being used for seals water-cooled brake drum sealing constituent to the lorry brake drum.
Background technique
Brake drum is the important component of motor-driven vehicle going safety, and is during the long descending of particularly big-and-middle-sized vehicle driving highway section, particularly important especially.According to Traffic Administration Bureau of Ministry of Public Security statistics, in recent years, major traffic accidents take place every year on average more than 300,000, and the accident that causes because of braking failure accounts for 30% of sum, above data are enough to explain the significance of brake drum to motor-driven vehicle going safety.At present, the general carrying capacity of goods carrying vehicle (particularly big-and-middle-sized goods carrying vehicle) does not all wait to tens tons at tens tons, increased by 3～4 times carrying capacity than original goods carrying vehicle, and the brake drum that uses still is original structure and common cast iron materials.Because kinetic energy was big when big-and-middle-sized goods carrying vehicle went; Therefore; Go long need continuously during apart from the descending highway section, braking for a long time; The heat that brake shoe and brake drum friction are produced makes the brake drum temperature continue to raise, and can reach 500 ℃～600 ℃ even higher usually, causes braking ability decay even inefficacy.For this reason, need brake drum is lowered the temperature, cooled off.At present, the common type of cooling is the open water pouring cooling to the brake drum trickle, and the situation that this mode is little for carrying capacity, the downhill path segment distance is short has effect preferably.Yet when length is gone apart from the descending highway section, but can not satisfy the cooling requirement of brake drum for heavy amount vehicle.This is because when the brake drum temperature is elevated to a certain degree, and the cooling water on the contact brake drum surface can form water vapor earlier, contacts with brake drum thereby hinder follow-up cooling water, has reduced the cooling effect of follow-up cooling water, causes the waste of cooling water; Simultaneously; Because the trickle mode all is that the direction brake drum waters pouring from the brake drum; Cooling water can only drench on a part of cambered surface of brake drum, causes the brake drum circumferencial direction uneven in temperature, and long this is prone to cause brake drum to break repeatedly; Cause the tragedy of car crash, bring heavy losses for people's lives and properties.In addition, because cooling water can not recycle, also there is the worry of frequent interpolation cooling water during long-distance running.
Summary of the invention
The purpose of the utility model is exactly the deficiency to existing technology; A kind of brake drum sealing constituent that is used for brake drum cooling is provided, when using this system and can make load-carrying vehicle go continuous skidding in long descending highway section immediately, also can cools uniformly brake drum enforcement; The braking quality that keeps braking system; Reduce heat fade, prolong brake drum working life, effectively reduce potential safety hazard because of braking quality reduces and brake drum breaks and brings; The further purpose of the utility model is to the cooling water recycle.
For realizing above-mentioned purpose, the utility model adopts following technological scheme.
A kind of brake drum sealing constituent; Comprise the axle components that is used for supporting wheel hub and vehicle frame, through the be rotationally connected brake drum of axle components one end of wheel hub; And be used for brake drum cooling and comprise the vehicle-mounted water system of water tank and water pipe; The periphery wall of said brake drum is provided with a ring-shaped water jacket, and an end of ring-shaped water jacket is provided with at least one water inlet, and the other end of ring-shaped water jacket is provided with at least one osculum; The sectional area summation of osculum is less than the sectional area summation of water inlet, and osculum perhaps is communicated with the backwater mouth of water tank through the water recovery apparatus that is provided with condenser with atmosphere; Said vehicle-mounted water system also comprises water supply installation, and water supply installation is movably connected on the axle components, and water supply installation can not have the ground of leakage injection pressure cooling water in ring-shaped water jacket through the water inlet.
After adopting technique scheme; When lorry brakes in the process of moving; The water supply installation of vehicle-mounted water system can seal the injection pressure cooling water through the water inlet in ring-shaped water jacket; Cooling water in the ring-shaped water jacket is to brake drum cooling, cooling; Water tank is discharged or taken back to heated water and water vapor from osculum, thus realize abundant cooling brake drum, keep braking system braking quality, reduce heat fade, guarantee braking effect, reduce the purpose of the traffic accident that causes because of the braking effect difference; Because ring-shaped water jacket is wrapped in the brake drum periphery; Therefore; Each the position cooling of brake drum circumference is even, simultaneously, also can perhaps in the reinforcement section of brake drum drum mouth a plurality of cooling hole that are exclusively used in its cooling be set through the reinforcement section that the water inlet is distributed on brake drum drum mouth; So that the reinforcement section cooling of brake drum drum mouthful evenly, avoid damaging the property loss brought and the generation of personal safety accident because of the brake drum that causes uneven in temperature breaks; In addition,, avoided the loss waste of cooling water, cooling water is fully utilized, reduced user cost because water supply installation does not have the ground of leakage injection pressure cooling water in ring-shaped water jacket; When heated water and water vapor through being provided with the water recovery apparatus of condenser, water and water vapor be cooled or be condensed into take back water tank behind the cold water after, can realize the purpose of cooling water recycle.The quantity that is provided with of water inlet and osculum is confirmed according to the concrete structure and the pore size of brake drum in this programme; Can be that one, two, three, four or other are natural a plurality of; Quantity preferably is evenly distributed on the circumference of brake drum during greater than one.
