Abstract
The utility model discloses a special brake shoe carrier for a Steyr front axle and a Steyr rear axle, which comprise an arc brake plate, a radial plate and two inner side arc ribbed plates. The arc brake plate is integrally connected with the two inner side arc ribbed plates through the radial plate, the cross section of the arc brake plate is in a double T-shaped structure, two ends of the arc brake plate are respectively provided with a reinforcing rib plate, and the arc brake plate, the radial plate and the two inner side arc ribbed plates are fixedly connected by the aid of the reinforcing rib plates. The arc brake plate, the two inner side arc ribbed plates, the radial plate and the reinforcing rib plates are integrally made by casting nodular cast iron materials, and the advantages of nodular cast iron, such as wear resistance, consistency and the like are reserved. The amount of the reinforcing rib plates is reduced due to the fact that only two ends of the arc brake plate are provided with the reinforcing rib plates, and accordingly, the weight of the arc brake plate is reduced. Besides, sizes and structural designs of the arc brake plate, the two inner side arc ribbed plates, the radial plate and the reinforcing rib plates and the like are correspondingly modified to reduce the weight of the brake shoe carrier on the premise that usability and service life of the brake shoe carrier can meet the requirement of an existing integral lorry.
Description
Technical field
The utility model relates to a kind of brake shoe carrier, relates in particular to the special-purpose brake shoe carrier of a kind of steyr front and back vehicle bridge.
Background technique
Along with China's Iron And Steel Industry technology improves constantly, be that raw-material quality or mechanical property have all obtained qualitative leap, heavily Ka deadweight and California bearing ratio improve and reduce cost to list in and heavily block the improved emphasis of automotive engineering.
The special-purpose brake shoe carrier of vehicle bridge all adopts the spheroidal graphite cast iron cast to form before and after original steyr, the special-purpose brake shoe carrier of vehicle bridge comprises arc keep plate, disc and two inboard arc gussets before and after this steyr, the arc keep plate is by disc and two inboard arc gusset quadratures, and cross section is double-T shaped structure, one end of arc dunnage is provided with the supporting pin attachment hole, and the other end is provided with the roller attachment hole; Arc keep plate, two inboard arc gussets and disc medial and lateral are laid with five and strengthen gussets, five strengthen gusset all with arc keep plate, disc and two inboard arc gusset quadratures.Though the special-purpose brake shoe carrier of vehicle bridge has advantages such as wear-resisting, that distortion is little before and after the steyr of said structure, but some position too abundant (as arc keep plate, two inboard arc gussets, disc and reinforcement gussets), hypertrophy in the former brake shoe structure, overall weight is big, seems heavy.When brake shoe and rest pin surface of contact when heavy wear need have been changed, and the intact nothing distortion in other position or damage, and excessive with other associated components great disparity in working life, thus cause uneconomical, applicability is relatively poor.
Brake shoe with steel plate punching press, assembly welding structure has appearred in existing market, and this kind structure brake shoe material has changed the mechanical property of its original brake shoe (adopting the spheroidal graphite cast iron cast to form) material fully, and steel plate and the contrast of spheroidal graphite cast iron mechanical property are as follows:
Can draw from last table: because that the elongation percentage of steel plate is compared spheroidal graphite cast iron is bigger, so brake shoe easily produces flow shape in loading process, thereby influence braking ability, secondly brake shoe and braking bottom board rest pin surface of contact are decreased to 7 millimeters, 10 millimeters by 14.5,23.9, because brake shoe, rest pin are the carbon structure steel, under dry condition, very easily produce damage and wearing and tearing, though this kind brake shoe weight saving, but braking effect, brake shoe are relatively poor relatively working life, have the defective of easy deformation simultaneously.
The model utility content
At above shortcomings part in the prior art, it is a kind of at the special-purpose brake shoe carrier of the steyr front and back of the prerequisite decline low weight that satisfies working life vehicle bridge that the utility model provides.
The purpose of this utility model is achieved in that the special-purpose brake shoe carrier of steyr front and back vehicle bridge, comprises arc keep plate, disc and two inboard arc gussets of being made by the ductile cast iron material casting; Described arc keep plate and two inboard arc gussets fuse by disc, and cross section is double-T shaped structure; The two ends of described arc keep plate are respectively equipped with the reinforcement gusset that arc keep plate, disc and two inboard arc gussets are fixedlyed connected.
Further, the middle part of described arc keep plate is provided with the reinforcement gusset that arc keep plate, disc and two inboard arc gussets are fixedlyed connected;
Further, the thickness of described reinforcement gusset is 5～7mm;
Further, described arc keep plate inner arc radius is R=185～190mm, and the thickness of arc keep plate is 5～8mm;
Further again, the inner arc radius of described two inboard arc gussets is 130～135mm, and the thickness of two inboard arc gussets is 6～12mm.
The special-purpose brake shoe carrier of vehicle bridge before and after the steyr of the present utility model compared with prior art, has following advantage:
1, the arc keep plate on the special-purpose brake shoe carrier of vehicle bridge, disc and two two inboard arc gussets, reinforcement gussets are formed by the ductile cast iron material cast inblock before and after the steyr, have therefore preserved advantages such as spheroidal graphite cast iron is wear-resisting, distortion is little; Only be provided with the reinforcement gusset at the two ends of arc keep plate simultaneously, the quantity of strengthening gusset reduces, and its weight is reduced.
2, heavily block under the prerequisite of car load requirement at present guaranteeing that usability, working life all can satisfy, carried out corresponding size-modify to adding positions such as arc keep plate, two inboard arc gussets, disc, reinforcement gusset, its thickness attenuation alleviates about making brake shoe weight by original 28kg to the 22kg.
