Abstract
The utility model relates to a kind of reinforced brake drum, it comprises brake drum body, the periphery in described brake drum body openings portion is provided with annular slot, is embedded with stiffening ring in described annular slot, and the diaxon end face of described stiffening ring is resisted against the two side of annular slot respectively.Adopt above structure, in brake drum body openings portion, periphery increases by a stiffening ring, and brake drum body and stiffening ring form an entirety, after brake drum braking surface cracking, stiffening ring plays banding effect, and when avoiding braking, braking surface opens, thus avoids braking failure.In addition, at brake drum body, stiffening ring position is installed and is provided with annular slot, play the effect blocking stiffening ring, avoid stiffening ring in use to deviate from.
Description
Technical field
The utility model relates to brake drum, is specifically related to a kind of reinforced brake drum.
Background technique
Be rotatable member during brake drum work, during braking brake shoe under actuation gear effect to inner rotary, the friction plate of outer surface presses against on the inner cylindrical surface of brake drum, drag friction is produced to drum and realizes braking, because friction catch can make break drum temperature raise rapidly, brake drum is caused to produce heat fatigue cracking, because of brake drum structure impact, brake drum opening part is more easy to crack, in use as occurred that brake drum ftractures, cause braking surface to open during braking, thus cause braking failure, vehicle safety cannot be ensured.This is also improve brake drum working life and avoided brake drum braking failure to have problem to be solved.Improve brake drum intensity, first should strengthen the intensity of brake drum opening portion, existing brake drum manufacturing firm mostly carries out thickening design at brake drum opening portion, improves opening part intensity; This design can improve opening part intensity, but causes braking surface to open during braking after also there is cracking, thus causes braking failure problem; Ye You producer increases collar at opening, but collar is in use easily deviate from.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides one to produce cracking phenomena, the reinforced brake drum of long service life.
For achieving the above object, the utility model is by the following technical solutions:
A kind of reinforced brake drum, comprise brake drum body, the periphery in described brake drum body openings portion is provided with annular slot, is embedded with stiffening ring in described annular slot, and the diaxon end face of described stiffening ring is resisted against the two side of annular slot respectively.
The width of described stiffening ring is 40-60mm.
The periphery of described brake drum body is provided with ring stiffener.
The utility model adopts above technological scheme, and in brake drum body openings portion, periphery increases by a stiffening ring, and brake drum body and stiffening ring form an entirety, after brake drum braking surface cracking, stiffening ring plays banding effect, and when avoiding braking, braking surface opens, thus avoids braking failure.In addition, at brake drum body, stiffening ring position is installed and is provided with annular slot, play the effect blocking stiffening ring, avoid stiffening ring in use to deviate from.Secondly, be also provided with ring stiffener at brake drum body periphery, ring stiffener can improve the intensity of brake drum further, adds the heat diffusion area of brake drum simultaneously, thus effectively can reduce the temperature of brake drum, improves the working life of brake drum.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail:
Fig. 1 is the generalized section of a kind of reinforced brake drum of the utility model;
Fig. 2 is the enlarged view at annular slot place in the utility model.
Embodiment
As shown in Figure 1 or 2, the utility model comprises brake drum body 1, the periphery of described brake drum body 1 opening portion is provided with annular slot 11, stiffening ring 2 is embedded with in described annular slot 11, the diaxon end face of described stiffening ring 2 is resisted against the two side of annular slot 11 respectively, stiffening ring 2 is shaping by alloy material, and by being fitted into after heat expansion in annular slot 11.Increase by a stiffening ring 2 at brake drum body 1 opening portion periphery, brake drum body 1 and stiffening ring 2 form an entirety, and after brake drum braking surface cracking, stiffening ring 2 plays banding effect, and when avoiding braking, braking surface opens, thus avoids braking failure.In addition, at brake drum body 1, stiffening ring 2 position is installed and is provided with annular slot 11, play the effect blocking stiffening ring 2, avoid stiffening ring 2 in use to deviate from.
The width of described stiffening ring 2 is 40-60mm, preferably 50mm.
The periphery of described brake drum body 1 is provided with ring stiffener 3.Ring stiffener 3 can improve the intensity of brake drum further, adds the heat diffusion area of brake drum simultaneously, thus effectively can reduce the temperature of brake drum, improves the working life of brake drum.
Claims (3)
1. a reinforced brake drum, comprise brake drum body, it is characterized in that: the periphery in described brake drum body openings portion is provided with annular slot, is embedded with stiffening ring in described annular slot, and the diaxon end face of described stiffening ring is resisted against the two side of annular slot respectively.
2. the reinforced brake drum of one according to claim 1, is characterized in that: the width of described stiffening ring is 40-60mm.
