Abstract
The utility model discloses a coupling structure between an undercarriage equipment compartment and a vehicle body, wherein, a bracketless suspension manner is adopted, the undercarriage equipment compartment is supported by static friction force that is generated between an equipment compartment mounting beam and an edge beam of an undercarriage of the vehicle body, a convex bracket does not needed to be arranged on the undercarriage of the vehicle body, and the heavy undercarriage equipment compartment is installed through a simplified positioning structure, so that the design difficulty for rigidity and strength of the undercarriage of the vehicle body can be reduced, and the component cost of the vehicle body can be lowered. The coupling structure between the undercarriage equipment compartment and the vehicle body comprises the mounting beam which is connected with the undercarriage equipment compartment, wherein, the mounting beam is fastened to the edge beam of the undercarriage of the vehicle body through a joint bolt; tightening torque that ranges from 150Nm to 200Nm and generated by the joint bolt is exerted to the edge beam of the undercarriage of the vehicle body; and a backing board is padded between the mounting beam and the edge beam of the undercarriage of the vehicle body. Larger tightening torque is exerted to the joint bolt, so that enough static friction force is generated between the mounting beam and the edge beam of the vehicle body so as to support the undercarriage equipment compartment.
Description
Technical field
The utility model is the connecting structure between a kind of chassis apparatus cabin and the car body, and connecting structure and the method that adopts no carriage to hang in the installing and locating process of the chassis apparatus cabin of guideway vehicle belongs to mechanical manufacturing field specifically.
Background technology
The high-speed track vehicle of present domestic design and use, as urban light rail, subway, motor train unit and passenger train etc., equipment compartment all hangs the location by the raised type carriage on the car body underframe under its car, and is aided with other fastening mounting structures.
Existing bracket type hangs position fixing system and method, requirement is reserved certain space to carriage, and owing to hold that the equipment compartment of equipment weighs about 10 tons under the car, therefore carrier structure itself requires to have the rigidity and the requirement of strength design of strictness, has proposed higher technical risk and component costs for the installing and locating of equipment under the car.
In addition, the equipment installation and positioning structure has increased the underframe volume and weight under the existing car, both has been unfavorable for improving the air resistance when overcoming the guideway vehicle operation, and has had influence on car body underframe light-weight design, is unfavorable for improving the operation speed per hour of guideway vehicle.
The utility model content
Connecting structure between chassis apparatus described in the utility model cabin and the car body, its design goal is to address the above problem with defective and adopts no carriage hang, rely on the static friction force that forms between equipment compartment mounting rail and the car body underframe side bar to support the chassis apparatus cabin, and need not on the car body underframe, to be provided with the raised type carriage, heavy weight chassis apparatus cabin to be installed, reduce design difficulty, reduction body part cost for car body underframe rigidity and intensity by the location structure of simplifying.
Another design goal is, realizes simplifying the car body Undercarriage structure, reduces the aerodynamic performance in car body deadweight and the raising high-speed cruising process.
For realizing above-mentioned design goal, the connecting structure between described chassis apparatus cabin and the car body mainly includes:
The mounting rail that connects the chassis apparatus cabin,
Mounting rail is fastened on the car body underframe side bar by tie bolt,
Tie bolt is applied in the screw-down torque of 150-200 ox rice on car body underframe side bar,
Liner has one deck backing plate between mounting rail and car body underframe side bar.
As above-mentioned basic scheme, by tie bolt being applied big screw-down torque, produce enough static friction forces between mounting rail and the car body side bar to support the chassis apparatus cabin, need not to go complex structure, the higher raised type carriage suspended structure of design difficulty are set, the safety factor of this type of connecting structure is higher again.
Be further to optimize the performance that relies on static friction force to support the chassis apparatus cabin, described backing plate (5), its thickness are not more than 15 millimeters and be not less than 5 millimeters.
For further improving safety factor, preventing to cause the chassis apparatus cabin to come off because of the tie bolt fracture, the innovative approach that can take is, be fastened with breaker bolt between mounting rail and car body underframe side bar, breaker bolt is connected on the adapter plate of car body underframe side bar inboard.
In sum, the connecting structure between the utility model chassis apparatus cabin and the car body has following advantage:
Adopt no carriage hang, rely on the static friction force that forms between equipment compartment mounting rail and the car body underframe side bar to support the chassis apparatus cabin, saved the setting of raised type carriage on the car body underframe, installation and positioning structure is simple, and safety factor is higher.
With the location structure of simplifying heavy weight chassis apparatus cabin is installed, reduces design difficulty, reduction body part cost for car body underframe rigidity and intensity.
Help realizing simplifying the car body Undercarriage structure, reduce the design that car body is conducted oneself with dignity, improve the aerodynamic performance of car body underframe in the high-speed cruising process effectively.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described further.
Fig. 1 is the connecting structure scheme drawing between described chassis apparatus cabin and the car body;
Fig. 2 is the generalized section of structure as shown in Figure 1;
As depicted in figs. 1 and 2, mounting rail 1, car body underframe side bar 2, tie bolt 3, breaker bolt 4, backing plate 5, adapter plate 6, car body side wall 7.
The specific embodiment
Connecting structure mainly comprises the mounting rail 1 that connects the chassis apparatus cabin.
One layer thickness is arranged is 10 millimeters backing plate 5 to liner between mounting rail 1 and car body underframe side bar 2.
Also be fastened with breaker bolt 4 between mounting rail 1 and car body underframe side bar 2, breaker bolt 4 is connected on the adapter plate 6 of car body underframe side bar 2 inboards, and adapter plate 6 is provided with cooresponding tapped bore.
Present embodiment has been realized a kind of new chassis apparatus cabin and the connecting method between the car body simultaneously, and the mounting rail 1 that promptly connects the chassis apparatus cabin is fastened on the car body underframe side bar 2 by tie bolt 3.
Apply the screw-down torque of 150-200 ox rice to tie bolt 3, mounting rail 1 is by forming the static friction force in support chassis apparatus cabin between backing plate 5 and the car body underframe side bar 2.
Also assist connection between mounting rail 1 and the car body underframe side bar 2, to increase the bonded assembly safe reliability by breaker bolt 4.
