Problems solved by technology
[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a stable structure, simple control, which can assist the steering and automatically reduce the speed during the turning process, so as to prevent the wounded from being thrown out. Vehicle anti-rolling braking device; In order to overcome the problem that the speed is not easy to control during the turning process, the present invention creatively proposes an inertial induction type roll feedback mechanism, a hydraulic induction type flexible transmission mechanism and a clutch type based on the feedback principle and the hydraulic structure principle. The roll deceleration mechanism captures and feeds back the lateral acceleration through the inertial induction type roll feedback mechanism, and controls the state of the clutch type roll deceleration mechanism through the linkage of the hydraulic induction type flexible transmission mechanism, thereby changing the rotation resistance of the traveling component, and then Control the speed of travel, without any active control mechanism and electric module, only through the ingenious mechanical structure, the technical effect of automatically reducing the speed when turning is realized

The invention discloses an anti-tilt braking device for a stretcher car used for outdoor nursing in field battles, which comprises an inertia induction type roll feedback mechanism, a hydraulic induction type flexible transmission mechanism, a stretcher car main body mechanism, a clutch type roll deceleration mechanism and an outward expansion type traveling mechanism. The invention belongs to the technical field of automatic braking devices, and specifically refers to an anti-rolling braking device for stretcher vehicles used in field and outdoor nursing; The lateral acceleration is captured and fed back through the inertial induction type roll reduction mechanism. If the state of the clutch type roll reduction mechanism is controlled through the linkage of the hydraulic induction type flexible transmission mechanism, the rotation resistance of the traveling component can be changed. , and then control the traveling speed. Without any active control mechanism and electric module, only through the ingenious mechanical structure, the technical effect of automatically reducing the speed when turning is realized.
Description
technical field [0001] The invention belongs to the technical field of automatic braking devices, and in particular refers to an anti-tilt braking device for a stretcher vehicle used in field and outdoor nursing. Background technique [0002] In field warfare, it is often necessary to use a stretcher to transport the wounded. However, due to the high speed of outdoor transportation, the stretcher needs to apply reverse thrust when turning to reduce the speed of the stretcher, otherwise it is easy to throw the wounded out. But braking while driving is very laborious, difficult to control, and dangerous. [0003] In addition, due to the rigidity of the overall structure and the stability of the stretcher, it is generally not equipped with a steering system. The difference in force between the two sides of the frame causes the stretcher to generate a force of lateral rotation, which causes the wheels on both sides to rotate. A speed difference is generated, and then the stretc...
