Abstract
The utility model relates to a disc brake bridge of a flat car, which comprises an axle, a rim and a tire. The axle can rotate, the rim is fixedly disposed on the axle, the tire is mounted on the rim, a disc brake is disposed on the axle and consists of a brake disc, a pair of brake friction blocks and brake control parts, the brake disc is rotationally disposed on the axle, the brake friction blocks are arranged on two sides of the brake disc, the brake control parts control braking of the brake friction blocks, and the pair of brake friction blocks can be in frictional contact with the two sides of the brake disc. The disc brake replaces a traditional drum brake, the brake disc rotates continuously and is exposed in air, heat is easy to be dissipated, moisture on the brake disc is easy to be dried, generated heat can be easily dissipated in the air, brake stability of the car can be ensured when the car runs, and degradation of brake capacity due to temperature rise or inlet water is avoided. Furthermore, the disc brake has the advantages of small volume, light weight, convenience in maintenance and the like.
Description
Technical field
the utility model relates to a kind of flatcar, and particularly dish relates to a kind of flatcar disc type brake bridge.
Background technique
flatcar is a kind of common vehicle of highway transport, because large-scale, the heavy goods of its more convenient loading and unloading, and than other kinds vehicle of same size, can load more goods, receives the favor of traffic unit deeply.
are present, and the used braking bridge of known flatcar is a drum brake.Drum brake is to lean on brake slipper on Brake drum, to compress to realize braking.The rotatable member of drum brake is a brake drum, and fixed element is a brake shoe, and to inner rotary, the friction plate of outer surface presses against on the inner cylindrical surface of brake drum brake shoe under the actuation gear effect during braking, and brake drum is produced friction brake torque.But drum brake is when frequent braking, and is frequent with the brake drum friction because of brake shoe, can produce big heat, and friction temperature raises rapidly, causes friction factor to descend, and stopping power is decline thereupon also, and above-mentioned phenomenon is called the heat fade of break.If water inlet in the break also can cause braking force to descend.Therefore, the drum brake heat dispersion is poor, and character of heat-fading is more obvious, and rainwater is difficult for again discharging after getting into break, can influence the vehicle braked effect equally.
Summary of the invention
The purpose of
the utility model provides a kind of flatcar disc type brake bridge.
For achieving the above object, the technological scheme that the utility model adopts is:
a kind of flatcar disc type brake bridge; It comprises the wheel shaft that can rotate, is fixedly installed on the wheel rim on the described wheel shaft and is installed in the tire on the described wheel rim; Described wheel shaft is provided with the disc type brake body, and described disc type brake body comprises the braking control piece that rotates the brake disc that is arranged on the wheel shaft, a pair of drag friction piece that is arranged on described brake disc both sides, the described drag friction piece braking of control; A pair of described drag friction piece can with the both sides rubbing contact of described brake disc.
preferably, described braking control piece comprise brake chamber, with the brake pushrod that described brake chamber matches, described brake pushrod is in transmission connection with a pair of described drag friction piece mutually.
further preferably, described wheel shaft is outside equipped with mounting plate, and described brake chamber is installed on the described mounting plate.
preferably, described brake disc is coaxial to be arranged on the described wheel shaft.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
the utility model adopts the disc type brake body to substitute traditional drum brake body; Wherein, owing to brake disc constantly rotates, and be exposed in the air; Be easy to dispel the heat and dry the moisture on the brake disc; The heat that generates is easy to loose in air, can guarantee vehicle insensitivity in motion, can Yin Wendu raise or water inlet causes stopping power to descend.
in addition, the disc type brake body has also that volume is little, quality is little and advantage such as easy to maintenance.
Description of drawings
accompanying drawing 1 is the structural representation of the utility model.
wherein: 1, wheel shaft; 2, wheel rim; 3, tire; 4, disc type brake body; 40, brake disc; 41, drag friction piece; 42, brake chamber; 43, brake pushrod; 5, mounting plate.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
A kind of flatcar disc type brake bridge that
are as shown in Figure 1, it comprises the wheel shaft 1 that can rotate, is fixedly installed on the wheel rim 2 on the wheel shaft 1 and is installed in the tire 3 on the wheel rim 2.
in the present embodiment: wheel shaft 1 is provided with disc type brake body 4, and disc type brake body 4 comprises and rotates the braking control piece that is arranged on the brake disc 40 on the wheel shaft 1, a pair of drag friction piece 41 that is arranged on brake disc 40 both sides, 41 brakings of control brake brake pad.Brake disc 40 coaxial being arranged on the wheel shaft 1, when wheel shaft drove tire 3 rotations, brake disc 40 also together rotated thereupon.
braking control piece comprises brake chamber 42, the brake pushrod 43 that matches with brake chamber 42, and brake pushrod 43 is in transmission connection with a pair of drag friction piece 41 mutually.
in addition, are outside equipped with mounting plate 5 at wheel shaft 1, and brake chamber 42 is installed on the mounting plate 5.
Below the concrete working principle of setting forth first present embodiment:
When
vehicle was exercised, rotating shaft 1 drove vehicle tyre 3 and rotates simultaneously with brake disc 40, and vehicle moves ahead; When braking; Brake chamber 42 air inlets are also passed through a pair of drag friction piece 41 of brake pushrod 43 promotions; Make drag friction piece 41 clamp the both sides of brake disc 40 simultaneously; Because brake disc 40 and rotating shaft 1 same shaft drive, the frictional force that drag friction piece 41 is clamped brake disc 40 makes rotating shaft 1 also stop operating to reach braking effect.
in addition; During braking, drag friction piece 41 is clamped brake disc 40 its surface friction meetings of back and is produced heat, after recovering to exercise; Because brake disc 40 constantly rotates with rotating shaft 1; And be exposed in the air, be easy to dispel the heat and dry the moisture on the brake disc 40, the heat of generation is easy to loose in air.Therefore, disk type braker can be guaranteed vehicle insensitivity in motion, can Yin Wendu raise or water inlet causes stopping power to descend.
the foregoing description is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.
