Abstract
The utility model provides a special brake drum for a truck, which comprises a brake drum main body, a reinforcing rib is arranged at the outer side of an opening part of the brake drum main body, and the upper part of the reinforcing rib is provided with a metal ring; and a plurality of countersunk retaining screws are arranged on the side face of the metal ring. Under the premise of not changing the original design shape and dimension of the brake drum, the serious defect that the truck brake fails because the brake drum made of a gray iron material is extremely easy to crack under poor environment is successfully overcome, and good wear resistance, deformation resistance and high friction coefficient of a cast iron brake drum can also be maintained.
Description
Technical field
The utility model relates to the load-carrying vehicle component, specifically is the special-purpose braking of lorry hub.
Background technique
Currently a variety of truck braking system brake hub assembly (especially the rear brake hub) are made of gray cast iron (HT250-HT300) Casting rough machining derived its rough shape and structure shown in Figure 1 , the figure 1 the main body of the brake Valley, 2 ribs, ribs 2 are located in the brake body 1, the openings of the valley, the reinforcing purpose, the structure and shape of the brake hub is characterized by: the system dynamic friction coefficient is high, the braking effect is good, brake hub itself in cold and hot environments, its resistance to deformation ability.But, the internal stress that produced when being in the suddenly cold and hot environment of the braking hub of this kind material is enough to cause braking hub body cracking, cause lorry forfeiture braking force, lead to the major accident of car crash.
Summary of the invention
The utility model purpose is the above-mentioned deficiency to gray iron material (HT250-HT300) braking hub, the special special-purpose braking of the lorry hub that proposes.
The technological scheme of the utility model does for this reason, and the special-purpose braking of lorry hub comprises braking hub body, and the opening portion outside of braking hub body is provided with stiffening rib, and it is characterized in that: described stiffening rib top is provided with metal ring.
Improvement to such scheme is: be provided with a plurality of countersunk head retaining screws in the side of described metal ring.
Beneficial effect:
The utility model under the prerequisite that does not change braking hub original design shape and size, successfully remedied gray iron material braking hub under poor environment very easily cracking make the lorry brake failure major defect, kept good antiwear property, non-deformability and the high coefficient of friction of cast iron braking hub simultaneously again.
Description of drawings
Figure 1 is a schematic structural view of the original brake valley.
Fig. 2 is the structural representation of the utility model.
1 is braking hub body among the figure, the 2nd, and stiffening rib, the 3rd, metal ring, the 4th, countersunk head retaining screw.
Embodiment
The utility model is as shown in Figure 2.
The special-purpose braking of lorry hub comprises braking hub body 1, and the opening portion outside of braking hub body 1 is provided with stiffening rib 2, is provided with metal ring 3 on stiffening rib 2 tops.
The side of metal ring 3 is provided with a plurality of countersunk head retaining screws 4.
Specifically adding man-hourMetal ring as shown in Figure 23 be heated to 700 ℃ it is expanded after, be embedded in stiffening rib 2 lateral parts of braking hub body 1 with 100 tons of press machine interference fit, thereby fix the hoop shape structure that the hub one is braked in formation.
The advantage that this lorry is braked hub with the existing cast iron quality of braking hub: friction resistant, resistance to deformation, high coefficient of friction; Have again than plain cast iron braking hub strong more than three times stretching resistance and do not change the outward appearance and the original size of braking hub.
Claims (2)
1. the special-purpose braking of lorry hub comprises braking hub body, and the opening portion outside of braking hub body is provided with stiffening rib, and it is characterized in that: described stiffening rib top is provided with metal ring.
According to right with require the special-purpose braking of 1 described lorry hub, it is characterized in that: be provided with a plurality of countersunk head retaining screws in the side of said metal ring.
