The specific embodiment
Below in conjunction with the drawings and specific embodiments rail wagon unit brake device of the present utility model is described in further detail:
Rail wagon unit brake device shown in the figure mainly transfers device 4, parts such as control pole socket 13, control stalk 17 and pipe link 15 to form by brake cylinder 6, force transferring lever 7, preceding drag chain 9, back drag chain 3, front brake lever 8, back brake lever 2, preceding brake beam 5, back brake beam 1, brake shoe 14, compression lock.Structural relation between each parts specifically describes as follows:
A. preceding brake beam 5 and back brake beam 1 are isosceles triangular structure, are arranged symmetrically in the both sides of truck bolster 20.Preceding brake beam 5 and back brake beam 1 are provided with pillar 10, and this pillar 10 is positioned on the midperpendicalar position of this isoceles triangle shape.Brake beam 5 and reliable, stressed being evenly distributed of back brake beam 1 Stability Analysis of Structures before the design-calculated are convenient to reasonable mounting arrangements brake cylinder 6 like this, satisfy the requirement of stationarity, reliability and the safety of railway truck braking.Before the two ends, the left and right sides of brake beam 5 and back brake beam 1 be installed with slide block 25, slide block 25 is embedded in the chute 22 on the truck side frame 21.Slide block 25 inboards, two ends, the left and right sides of brake beam 5 and back brake beam 1 before brake shoe 14 is installed in.When the slide block 25 on current brake beam 5 and the back brake beam 1 moves with respect to chute 22, can drive brake shoe 14 and be close to or leave wheel 23.
B. the lower end of front brake lever 8 is hinged on the pillar 10 of preceding brake beam 5, one end of the upper end of front brake lever 8 and preceding drag chain 9 is hinged, the other end of preceding drag chain 9 and an end of force transferring lever 7 are hinged, the middle part of force transferring lever 7 is hinged on the balance pivot seat 18 on the truck bolster 20, the other end of force transferring lever 7 and brake cylinder 6 are hinged, and brake cylinder 6 is installed on the truck bolster 20 by brake cylinder seat 12.Also be provided with the pin-and-hole 11 that can link to each other in the upper end of front brake lever 8, the application of force direction of hand brake device is shown as arrow B among Fig. 2 with hand brake device.When Pneumatic brake cylinder 6 can't be worked, can spur front brake lever 8 by hand brake device, and then the drive miscellaneous part is finished the braking to wheel 23.
C. the lower end of back brake lever 2 is hinged on the pillar 10 of back brake beam 1, and the upper end of back brake lever 2 is hinged with an end of back drag chain 3, and the fixed pivot seat 19 on the other end of back drag chain 3 and the truck bolster 20 is hinged.
D. the compression lock transfers the front end of device 4 to be hinged on the middle part of front brake lever 8, and the compression lock transfers the rear end of device 4 to be hinged on the middle part of back brake lever 2.The compression lock transfers the front end of device 4 to be provided with handlebar 16, and the middle part of handlebar 16 is hinged on the compression lock and transfers in the front end bar-shaped trough of device 4.The one end through hole of handlebar 16 and the polished rod section bearing fit of control stalk 17, the thread segment of control stalk 17 cooperates with the threaded one end of control pole socket 13, and the other end of control pole socket 13 is hinged on the front brake lever 8.One end of the other end of handlebar 16 and pipe link 15 is hinged, and the other end of pipe link 15 and the pipe link permanent seat 24 on the bogie truck are hinged.
When brake shoe 14 or wheel 23 abrasion, generally can cause the gap increase between brake shoe 14 and the wheel 23; When brake shoe 14 or wheel 23 renew, generally can cause the gap between brake shoe 14 and the wheel 23 to be reduced.Long or the shortening of automatic accent that transfer device 4 by the compression lock this moment can keep the piston stroke of brake cylinder 6 to be stabilized in the dimension limit of regulation.As shown in Figure 4, leave gap A between the polished rod section end boss of control stalk 17 and the end through hole of handlebar 16, the cooperate degree of the thread segment of lever for adjusting oil 17 and control pole socket 13 can determine the size of gap A, thus the piston stroke length of control brake cylinder 6.
Principle of work of the present utility model is such: when vehicle is implemented the wind glancing impact, brake cylinder 6 promotes force transferring lever 7, force transferring lever 7 is given front brake lever 8 with force transmission, controls pole socket 13 this moment and can move by drive control stalk 17, makes itself and joystick 16 produce relative displacemenies.After gap A eliminates, when front brake lever 8 continuation are mobile, 17 of control stalks can spur joystick 16, thereby triggering the compression lock transfers device 4 to move, the compression lock transfers device 4 to transfer long or shortening automatically according to the size of taking turns watt gap, and gives back brake lever 2 with force transmission, and brake beam 5 and back brake beam 1 slide in the chute 22 of truck side frame 21 before front brake lever 8 and 2 drives of back brake lever, drive brake shoe 14 and be adjacent to wheel 23, thereby realize car brakeing.
When vehicle is implemented when hand braking, get final product with the hand brake device pulling front brake lever 8 that is connected in the front brake lever 8 upper end pin-and-holes 11, the action of miscellaneous part is the same.
