Abstract

The utility model discloses a wheel brake shoe, which comprises a semicircular shoe plate, wherein, a friction plate is fixedly connected to the outside of the shoe plate and a pectoral plate is fixedly connected to the inside of the shoe plate; one end of the pectoral plate is provided with a flat plate; the surface of the pectoral plate is provided with round holes; the other end of the pectoral plate is provided with a supporting pin hole the section of which is semicircular; the shoe plate and the pectoral plate are steel plate stampings and fixed through welding; and the friction plate is fixed on the shoe plate through riveting. The wheel brake shoe has the advantages that: the structure is reasonable; the technique is simpler; the weight is lighter than that of a casting piece; the strength is larger; the wheel brake shoe is tougher and difficult to damage; and more materials are saved and the manufacturing cost is reduced on the premise that the braking performance is unchanged.

Description

A kind of wheel braking hoof

Technical field

The utility model relates to a kind of farm machinery accessory, particularly a kind of farm machinery wheel braking hoof.

Background technique

In recent years, under the energetically promotion of country to the agriculture, rural areas and farmers cause, the manufacturing industry of farm machinery is also just grown in strength at high speed development, the production scale of farm machinery is developed to intensive style by extensive style, manufacturing process is also more and more advanced, develop into legerity type gradually from heavy type, mobile type and practical, the wheel braking hoof is an easily damaged parts, is in great demand, at present, the wheel braking hoof is generally casting and forms, and every pair of brake shoe all needs two to support bearing pin, manufacturing process complexity, weight is bigger, fragile, and increased complete vehicle weight virtually, make rolled steel dosage strengthen, manufacturing cost and use cost also increases.

The model utility content

The technical problems to be solved in the utility model provides the wheel braking hoof of a kind of economical with materials more and manufacture cost.

For solving the problems of the technologies described above, a kind of wheel braking hoof of the present utility model, comprise semicircular hoof plate, the hoof plate outside is fixedly connected with friction plate, hoof plate inboard is fixedly connected with web, one end of web is provided with a flat board, and web surface is provided with circular hole, and it is semiorbicular support pin-and-hole that the other end of described web is provided with the cross section.

Described hoof plate and web are steel stamping parts, and hoof plate and web are fixing by welding.

Described friction plate by riveted fixing on the hoof plate.

Adopt technique scheme, structure of the present utility model is reasonable more, manufacturing is easier, this wheel braking hoof is symmetrical arranged when installing, uses in pairs, one end of web is provided with the support pin-and-hole that the cross section is a semi-round ring shape, two shared one of brake shoes support bearing pin, under the constant prerequisite of braking ability, more economical with materials and manufacture cost, alleviated complete vehicle weight; Hoof plate and web are steel stamping parts; hoof plate and web are fixing by welding; friction plate by riveted fixing on the hoof plate; such manufacturing process is simpler, can maximize, the production of scale, intensification, and the weight ratio cast member is light; intensity strengthens; flexible is not fragile more, and extend working life.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the plan view of Fig. 1.

Embodiment

As depicted in figs. 1 and 2, a kind of wheel braking hoof of the present utility model, comprise semicircular hoof plate 1, hoof plate 1 outside is fixedly connected with friction plate 2, and hoof plate 1 inboard is fixedly connected with web 3, one end of web 3 is provided with a flat board 4, web 3 surfaces are provided with circular hole 5, and the other end of web 3 is provided with the support pin-and-hole 6 that the cross section is a semi-round ring shape, and hoof plate 1 and web 3 are steel stamping parts, on hoof plate 1, hoof plate 1 and web 3 are fixing by welding by riveted fixing for friction plate 2.

The utility model is rational in infrastructure, and technology is simpler, and the weight ratio cast member is light, and intensity strengthens, and flexible is not fragile more, under the constant prerequisite of braking ability, and economical with materials and manufacture cost more.
