Technical Field

[0001] The utility model relates to the field of vehicles, and particularly to a suspension device in vehicles. Background Art

[0002] The suspension device is one of the conventional accessories of transportation vehicles such as trailers and semi-trailers. The existing suspension device includes a guide arm bracket and a guide arm. The front part of the guide arm is installed on the guide arm bracket through a mounting shaft. The guide arm bracket includes two parallel vertical plates, and the guide arm is located between the two vertical plates. Mounting holes are provided on both the guide arm and the guide arm bracket. A ring sleeve is provided on the mounting hole of the guide arm, and the mounting shaft passes through the mounting hole of the guide arm bracket and the ring sleeve respectively, thereby realizing the connection between the guide arm and the guide arm bracket.

[0003] During the use of the suspension device, the guide arm is prone to swing between the two vertical plates. Of course, a gasket can also be provided between the guide arm and the vertical plate, but the gasket is prone to friction and wear with the guide arm or the guide arm bracket. At the same time, during the use of a conventional circular gasket, the ring sleeve on the guide arm is prone to wear. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a guide arm gasket and a suspension device equipped with the guide arm gasket, aiming to solve the problem that the gasket of the existing suspension guide arm is severely worn.

[0005] A guide arm gasket provided by the utility model includes a plate body. A chute extending from the lower part to the middle part is provided on the plate body. The ring sleeve of the suspension guide arm is snapped into the chute and slides in the chute. A through hole is provided in the chute, and the mounting shaft of the suspension guide arm passes through the through hole.

[0006] Preferably, the thickness of the guide arm gasket gradually decreases from front to back.

[0007] More preferably, a slope is provided on the front side of the chute.

[0008] Preferably, a protrusion is provided on the back surface of the plane where the chute is located, and the protrusion is used for clamping and fixing.

[0009] Preferably, the guide arm gasket is made of nylon material.

[0010] Preferably, the chute extends from the lower part to the upper middle part of the plate body.

[0011] The present utility model also provides a suspension device, which includes a bracket and a guiding arm. A guiding arm bracket is provided at the front end of the guiding arm. Both the guiding arm bracket and the guiding arm are provided with mounting holes, and the mounting holes penetrate through the mounting holes of the guiding arm bracket and the mounting holes of the guiding arm. A ring sleeve is provided in the mounting hole of the guiding arm, and the ring sleeve extends out of the arm body of the guiding arm. The guiding arm gasket is arranged between the ring sleeve of the guiding arm and the inner side plate of the guiding arm bracket.

[0012] Compared with the prior art, the guiding arm gasket provided by the present utility model and the suspension device equipped with the guiding arm gasket have the following beneficial effects:

[0013] For the above-mentioned guiding arm gasket and the suspension device equipped with the guiding arm gasket, the gasket includes a plate body, but a chute is provided on the plate body. When in use, the ring sleeve is clamped into the chute, which can avoid excessive wear of the ring sleeve. At the same time, the plate bodies on both sides of the chute contact the side plates of the guiding arm and the guiding arm bracket, and the thickness at this place is relatively large and far from the ring sleeve, which can improve the anti-wear ability of the gasket.

[0014] Furthermore, a chute for placing the ring sleeve is provided on the plate body, and the ring sleeve can slide in the chute. The design of this chute also facilitates the installation of the gasket and the guiding arm, and the chute plays a role of guiding and positioning. Description of the Drawings

[0027] Embodiment 1

[0028] This embodiment provides a guide arm gasket. The guide arm gasket includes a plate body 1, and a chute 2 extending from the lower part to the middle part is arranged on the plate body 1. The collar of the suspension guide arm is snapped into the chute 2. When installing the guide arm, the guide arm moves upward from the bottom, and the collar of the guide arm moves up and down in the chute 2. The chute 2 can play a role in guiding and positioning. A through hole 3 is arranged in the chute 2. When the mounting holes of the guide arm and the guide arm bracket are aligned, the mounting shaft passes through the mounting hole of the guide arm bracket, the through hole 3, and the collar in the mounting hole of the guide arm at one time, realizing the installation of the guide arm bracket, the guide arm gasket, and the guide arm.

[0029] For the above-mentioned guide arm gasket, the gasket includes a plate body 1, but a chute 2 is arranged on the plate body 1. When in specific use, the collar is snapped into the chute 2, which can avoid excessive wear of the collar. At the same time, the plate body 1 on both sides of the chute 2 contacts the side plates of the guide arm and the guide arm bracket. The thickness here is relatively large and far from the collar, which can improve the wear resistance of the gasket. Moreover, a chute 2 for placing the collar is arranged on the plate body 1, and the collar can slide in the chute 2. The design of the chute 2 also facilitates the installation of the gasket and the guide arm, and the chute 2 plays a role in guiding and positioning.

[0030] Specifically, in this embodiment, the above-mentioned guide arm gasket should adapt to the guide arm and the guide plate bracket. In this embodiment, when the width of the guide arm gradually decreases from front to back, the thickness of the guide arm gasket gradually decreases from front to back.

[0031] More specifically, to avoid interference between the outer side of the collar or the weld for connecting the collar and the chute, a slope is arranged on the front side of the chute.

[0032] Specifically, in this embodiment, in order to fix the guide arm gasket, a protrusion 4 is arranged on the back surface of the plane where the chute 2 is located. The protrusion 4 is used for clamping and fixing. Correspondingly, holes or grooves corresponding to the protrusion 4 should be arranged on the vertical plate of the guide arm bracket to realize the fixation of the guide arm gasket.

[0033] Specifically, in this embodiment, in order to reduce the friction coefficient, the guide arm gasket is made of nylon material.

[0034] Specifically, in this embodiment, the chute 2 extends from the bottom to the upper middle part of the plate body 1.

A collar is provided in the mounting hole of the guide arm, and the collar extends out of the arm body of the guide arm. A guide arm gasket as described in Embodiment 1 is provided between the collar of the guide arm and the inner side plate of the guide arm bracket.

[0037] For the above suspension device equipped with a guide arm gasket, the collar extends out of the arm body of the guide arm. A chute 2 is provided on the plate body 1. During specific use, the collar is snapped into the chute 2, which can avoid excessive wear of the collar. At the same time, the plate body 1 on both sides of the chute 2 contacts the side plates of the guide arm and the guide arm bracket. The thickness at this place is relatively large and far from the collar, which can improve the anti-wear ability of the gasket. A chute 2 for placing the collar is provided on the plate body 1, and the collar can slide in the chute 2. The design of the chute 2 also facilitates the installation of the gasket and the guide arm, and the chute 2 plays a role of guiding and positioning.
