In the embodiments of the present application, a leaf spring applied to a light truck running gear is provided, and for convenience of explanation and understanding, the following contents are provided on the basis of the structure of the illustrated product. Of course, it is understood by those skilled in the art that the above-described structure is only used as a specific example and illustrative illustration, and does not constitute a specific limitation to the technical solution provided by the present application.
As shown in fig. 1 and 2, a leaf spring applied to a light truck traveling system is mounted on a frame 1 of the light truck traveling system, the frame is provided with a limit bracket 11 for limiting the leaf spring, specifically, the leaf spring includes a main spring group 21 and an auxiliary spring group 22 disposed above the main spring group 21, the main spring group 21 is connected to the frame 1 through a leaf spring bracket 23, an anti-wear portion 24 is disposed at an end portion of the auxiliary spring group 22, and the auxiliary spring group 22 abuts against the limit bracket 11 through the anti-wear portion 24 when deformed.
As can be understood by those skilled in the art, in the application, the leaf spring only works in the main spring group 21 during no-load and static load while ensuring the load of the vehicle, so as to improve the comfort, and when goods are transported or severe impact is received, the auxiliary spring group 22 participates in the pressure bearing of the vehicle, so that the smoothness of the vehicle form is improved. Moreover, the anti-abrasion part 24 is arranged at the end part of the auxiliary spring group 22, when the auxiliary spring group 22 is elastically deformed, the anti-abrasion part 24 is abutted against the limiting bracket 11, so that the auxiliary leaf spring in the auxiliary spring group 22 is prevented from being excessively abraded by the limiting bracket 11 to reduce the structural strength of the leaf spring, the service life of the leaf spring is ensured, the maintenance cycle of the vehicle is prolonged, and the reduction of the vehicle cost of a user is facilitated.
Specifically, can set up two spacing supports 11 on frame 1, two spacing supports 11 are close to the both ends setting of vice spring group 22 respectively, simultaneously, can also all set up wearing parts 24 at the both ends of vice spring group 22, and when vice spring group 22 took place to warp, the perk that makes progress in both ends was through wearing parts 24 and spacing support 11 collision contact, and then avoided vice leaf spring to take place excessive wearing and tearing.
It should be noted that the structure of the wear-proof portion 24 is not specifically limited, and any one of the following embodiments may be adopted:
The wear-resistant plate has simple structure, easy processing and manufacturing and lower cost.
The connection mode of the wear-resistant plate is not particularly limited in the present application, and the wear-resistant plate may be connected with the auxiliary leaf spring in the auxiliary spring group 22 in a non-detachable mode, such as welding; it can also be detachably connected with the auxiliary leaf springs in the auxiliary spring group 22, such as screw connection, bolt connection, etc., and the wear-resistant plate can be detached to replace the old wear-resistant plate with serious wear so as to ensure the wear-resistant performance.
Further, as shown in fig. 4, the wear plate may be provided with a mounting hole, the auxiliary spring set 22 is provided with a threaded hole, and the leaf spring further includes a first bolt connector 25, wherein the first bolt connector 25 penetrates through the mounting hole and is connected with the threaded hole to detachably connect the wear plate and the auxiliary spring set 22.
Through the fixed wear plate of first bolted connection 25, the reliability is high, installation stability is strong, avoids the wear plate to drop from vice spring group 22, moreover, easy dismounting, swift.
As a preferred example under this embodiment, the mounting hole is provided as a counterbore, and the screw head of the first bolt connection 25 is located inside the counterbore.
As can be understood by those skilled in the art, the mounting hole is set as a counterbore, and the screw head of the first bolt connector 25 is located inside the counterbore, so that the screw head can be prevented from protruding out of the outer surface of the wear-resistant plate, and further, the situation that the pretensioning effect of the first bolt connector 25 is reduced due to the contact and friction between the screw head and the limiting bracket 11 is avoided.
As a preferred example of the present embodiment, a replacement warning structure may be provided at a central position of a side portion of the wear plate.
