Description
Technical Field
The utility model belongs to the technical field of machinery, concretely relates to mechanism on integrated online accuse chassis frame of bush.
Background
The line control chassis of the unmanned logistics vehicle generally comprises a frame, a steering system, a suspension system, an electrical system, an anti-collision module and other parts. With the development of unmanned technology and the requirements of various special application scenes, applications such as unmanned distribution, unmanned cleaning, unmanned disinfection, unmanned logistics, unmanned ferry and the like emerge in endlessly. The existing suspension system generally adopts a connecting rod and frame lifting lug connecting scheme. Wherein, the lug can design thicker auricle, increases the reliability. However, when the suspension is jumped, the connecting rod can rotate around the lifting lug to generate a torsion force, so that the welding point of the lifting lug is fatigue, and the durability and reliability of the lifting lug and the frame can be further influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the not enough of prior art, improve connecting rod and connected to frame's steadiness.
The utility model discloses a following technical scheme realizes: a bushing-integrated chassis frame mechanism comprising: the lifting device comprises a frame (3), a positioning sleeve (1), a bushing (2), a connecting rod (6) and a lifting lug (8), wherein the positioning sleeve (1) is integrated on the frame (3), and the bushing (2) is fixed in the positioning sleeve (1); one end of the connecting rod (6) is connected with the bushing (2), the bushing (2) twists around the positioning sleeve (1) to transmit torque to the frame (3), and the other end of the connecting rod (6) is connected with the lifting lug (8).
Further, the connecting rod (6) comprises a head (601), and a middle hole (602) is formed in the head (601); the lifting lug (8) comprises a top surface (801) and a side wing (802), a screw hole (803) is formed in the side wing (802), and the connecting rod (6) and the lifting lug (8) are fixed through a screw by the middle hole (602) and the screw hole (803).
Furthermore, the device also comprises a reinforcing rib (4), a partition plate (5) and a fixing plate (7).
Compared with the prior art, the utility model has the advantages of it is following: the utility model discloses bush (2) integration is on frame (3), and then increases connecting rod (6) structural strength when receiving the moment of torsion around screw (803) position, prevents that fixed connection position fatigue from appearing in connecting rod (3) at reciprocating motion's in-process, improves the intensity at fixed connection position and frame (3).

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1-2, a mechanism in which a bush is integrated on a drive-by-wire chassis frame includes: the device comprises a frame 3, a positioning sleeve 1, a bushing 2, a connecting rod 6 and a lifting lug 8, wherein the positioning sleeve 1 is integrated on the frame 3, and the bushing 2 is fixed in the positioning sleeve 1; one end of the connecting rod 6 is connected with the bush 2 by adopting a U-shaped gasket, the bush 2 twists around the positioning sleeve 1 to transmit torque to the frame 3, and the other end of the connecting rod 6 is connected with the lifting lug 8.
As shown in fig. 3-4, the connecting rod 6 includes a head 601, and a central hole 602 is formed on the head 601; the lifting lug 8 comprises a top surface 801 and a side wing 802, a screw hole 803 is arranged on the side wing 802, and the connecting rod 6 and the lifting lug 8 are fixed through a screw by the middle hole 602 and the screw hole 803. Top surface 801 is welded to the bottom of the suspension system.
Preferably, the vehicle frame further comprises a reinforcing rib 4, a partition plate 5 and a fixing plate 7, wherein the reinforcing rib 4 and the partition plate 5 are used for arranging electrical components and further enhancing the structural strength of the vehicle frame 3, and the fixing plate 7 is used for placing a storage battery.
When the suspension makes reciprocating jump, the bush 2 rotates around the positioning sleeve 1, thereby generating torsion at the connecting position of the positioning sleeve 1 and the frame 3. The locating bush 1 is fitted into the frame 3 to allow the bush 2 to deform but not rotate relative to it.
