Abstract
The utility model relates to a flexibly connecting auxiliary frame for a vehicle. The rear end of the flexibly connecting auxiliary frame for a vehicle is fixed by bolts and is connected to a main frame by two rear supports, and the front end uses a hinging seat, a hinging shaft and an equalizing beam on the main frame to form a flexible connection. The utility model relieves the rigid constraint of the auxiliary frame for the main frame, improves a stress state, avoids the load concentration or breaking of the main frame, and enhance the service life of the frame for the vehicle.
Description
The utility model belongs to the cycle frame structure of vehicle field.
Subframe is the important component part of vehicle.Because the intensity of apparatus for work and the requirement of structure, each of subframe all requires very big to rigidity, as adopting the car hosit of universal chassis, various tank cars and bulk cement car or the like.The subframe front and back end all adopts the mode of being rigidly connected to be connected on the main car frame, as shown in Figure 1 at present.When vehicle ' makes one to take turns and lift or sink on uneven road surface often, because the rigid constraint effect of subframe, stress raisers will take place because of the distribution of load of two beams is uneven in the main car frame leading portion, make it produce plastic deformation even cracking, have a strong impact on the service life of vehicle frame.
The purpose of this utility model is a kind of subframe of invention, and it is connected to flexible-disc joint with the main car frame front end, removes the rigid constraint of subframe to main car frame, makes the load that acts on two beams of main car frame balanced as far as possible, the service life of raising main car frame.
A kind of subframe of flexible-disc joint, two rear supports in its rear end (4), (5) are fixedly connected on the main car frame (8) with bolt (6), (7), its front end is formed flexible-disc joint with free bearing (1), hinge (2) with the equalizer on the main car frame (3), sees accompanying drawing 2.Should leave enough gap △ between the major-minor vehicle frame, the △ value is generally more than the 30-50 millimeter, with allow between the two in rotation.The size design of each several part should be decided according to suffered load.Free bearing should carry out after assembling with being connected of subframe.Equalizer can utilize the crossbeam of former main car frame to reinforce, and also can manufacture in addition.
Adopt above-mentioned connection mode, the major-minor vehicle frame will improve strained condition greatly, avoid the stress concentration or the fracture of vehicle frame, improve its service life.
(1), (2) are rigid mount in the accompanying drawing 1, and (3), (4) are tie bolt, and (5) are main car frame, and (6) are subframe.
(1) is free bearing in the accompanying drawing 2, and (2) are hinge, and (3) are equalizer, and (4), (5) are rigid mount, and (6), (7) are tie bolt, and (8) are that main car frame, (9) are subframe, and △ is gap between the major-minor vehicle frame.
Claims (1)
- A kind of subframe of flexible-disc joint, two rear supports in its rear end [4], [5] are fixedly connected on the main car frame [8] with bolt [6], [7], it is characterized in that subframe front end free bearing [1], hinge [2] are with the equalizer on the main car frame [3] composition flexible-disc joint, should leave certain interval △ between main car frame [8] and the sub frame [9], the △ value is generally got more than the 30-50 millimeter.
