Each car body module according to the guideway vehicle of the utility model all is the structure with integral type; Therefore add in the guideway vehicle or from guideway vehicle with the form of module easily and remove; Change the quantity of car body module in the guideway vehicle thus, and therefore change the length and the carrying capacity of guideway vehicle.
For example, in example shown in Figure 5, guideway vehicle has increased a pair of car body module, and promptly car body and one of a band bogie truck is not with the car body of bogie truck.Like this, just constituted seven modular guideway vehicles shown in Figure 5, it has seven power truck 10-1 and one and pulls round frame 10-2.Similar in the five modular guideway vehicles among the configuration of the drg on each bogie truck and Fig. 3 no longer is repeated in this description.A kind of remodeling that has shown seven modular guideway vehicles among Fig. 6 is respectively equipped with an electro-hydraulic brake device 30 at the two ends of the every axletree that pulls round frame 10-2.Be appreciated that each power truck 10-1, can be respectively equipped with an electro-hydraulic brake device 30 at the two ends of every axletree equally for seven modular guideway vehicles.
Shown a kind of caliper disc electro-hydraulic brake device that is used for rail vehicle truck among Fig. 7-9 according to the utility model.Wheel 11 and axletree 12 have also been schematically shown among Fig. 7-9.In embodiment illustrated, the electro-hydraulic brake device of the utility model is arranged on the wheel inboard, promptly between the framework of wheel and bogie truck.Certainly, the utility model is not got rid of the situation that the electro-hydraulic brake device is arranged on lateral wheel.
The electro-hydraulic brake device of the utility model mainly comprises: brake disc 1, and it is installed on the axial region that stretches out from the framework side of axletree; Brake clamp assembly 2, it is installed on the framework of bogie truck, is used for brake disc is implemented braking.Brake disc 1 limits three quadrature-axis that intersect at its center O: be parallel to the horizontal X axle on brake disc plane, vertical Z axle and perpendicular to the horizontal Y axle on brake disc plane.
The Clamping force of utilizing mechanical pressure device to be provided to brake disc 1 by brake clamp 6 is adjustable, and for example each brake clamp can provide the Clamping force of maximum 45kN.
Have the bogie truck of this electro-hydraulic brake device for each,, all be equipped with, be used to discharge three other braking forces of level noted earlier of brake clamp and control brake pincers by independent hydraulic pressure unit no matter be power truck or pull round frame.In addition, each bogie truck also is equipped with auxiliary electrical liquid releasing unit, is used for when breaking down, discharging brake clamp.In addition, each bogie truck also is equipped with Hydraulic Pump control module or the like.The Hydraulic Pump control module is received the control of drg control unit, like this, and through the operation of drg control unit may command electro-hydraulic brake device.
Hydraulic accumulator also is equipped with for pulling round frame,, so that store and practice thrift the hydraulic energy in the hydraulic pressure unit.
Each brake lining 7 respectively above that the lower part by the guide guiding that is installed in guide rod 9 forms on the housing, so that brake lining 7 can accurately move along the direction that is parallel to the Y axle.
According to the utility model; The centre of form in the useful effect zone (with the zone of friction disc 1 wipe contact) of each brake lining 7 is positioned at X axle top; Promptly; Line between the centre of form in the useful effect zone of the center O of brake disc 1 and brake lining 7 and the angle between the Z axle are less than 90 degree, that is, this angle is more than or equal to 0 degree but less than 90 degree.This angle is preferably 15 degree to 75 degree, and more preferably 30 degree are preferably spent to 65 degree 40 to 70 degree.
Opposite extreme situations is, this angle is 0 degree, and promptly the centre of form of brake lining 7 is positioned on the Z axle, although this opposite extreme situations in reality because other restriction and preferably not adopting.
According to a kind of preferred implementation, for example, form angle theta between central axis between the interior outer end of brake clamp 6 and the X axle.This central axis can intersect with the Y axle.
According to the utility model; Because the centre of form in the useful effect of each brake lining 7 zone is positioned at X axle top; Therefore brake lining 7 is not above the braking force F that produces on the brake disc 1 is sensing vertically; Promptly be not parallel with the Z axle, but with Z axle shape at an angle, this angle equals line and the angle between the Z axle between the regional centre of form of center O that 90 degree deduct brake disc 1 and the useful effect of brake lining 7 substantially.Like this, braking force F has along the vertical component of Z-direction with along the horizontal component of X-direction.Prior art with among Fig. 1 is compared, and under the situation of identical braking force F, the vertical component of the braking force F of the utility model is less than the situation (being equal to braking force F) of the prior art among Fig. 1.Therefore, the moment around bogie truck longitudinal axis (being parallel to the X axle) of the braking force of bogie truck both sides generation is compared with prior art and has been reduced.Bogie truck and even car body are alleviated around the phenomenon of bogie truck longitudinal axis left and right sides deflection.
According to the preferred implementation of the utility model, each electro-hydraulic brake device is provided with automatically regulating mechanism, so that compensation is made in the wearing and tearing of brake lining 7, thereby always keeps the suitable gap between brake lining 7 and the brake disc 1.
The material of brake lining 7 should be discharged environmentally harmful material, for example asbestos, lead, zinc etc.
Although the situation that the brake clamp assembly of electro-hydraulic brake device comprises a pair of brake clamp and pair of brake pads has been described in the front, the brake clamp assembly that the utility model also comprises the electro-hydraulic brake device only comprises the situation of a brake clamp and a brake lining.
Bogie truck of the utility model and electro-hydraulic brake thereof are applicable to various guideway vehicles, especially tramway train.
Below only be that preferred implementation to the utility model is described; Should be understood that; For those skilled in the art of the present technique; Under the prerequisite that does not break away from the utility model principle, can also make various improvement and substitute, these improvement and substitute and also should be regarded as dropping in the protection domain of the utility model.
