Description

Technical Field

[0001] This utility model relates to the field of rear suspension assembly technology, specifically a rear suspension assembly for an ATV. Background Technology

[0002] The rear suspension assembly of an ATV is a key component of the vehicle's chassis system. It is mainly used to support the rear wheels, buffer road impacts, maintain tire grip, and improve driving comfort and handling stability.

[0003] For example, the Chinese authorized patent CN207173182U (A Beach Bugatti Rear Axle Assembly) includes a swingarm assembly. The top of the swingarm assembly has a rear fork inner liner tube, and the inner liner tube has a bottom axle. The bottom axle has a chain guide and a rear swingarm bearing. The bottom of the swingarm assembly has a rear axle. The swingarm assembly and the rear axle are fixedly connected by bolts and nuts. Rear wheel seats are located at both ends of the rear axle. The rear axle on one side of the swingarm assembly has a sprocket connecting seat, a sprocket, a bearing, and a rear axle cylinder. The rear axle on the other side of the swingarm assembly has a rear brake positioning sleeve, a rear brake disc fixing seat, and a rear brake disc. This utility model provides a beach buggy rear axle assembly with a reasonable structural design, high strength, flexible rotation after connection to the frame, safety and reliability, and simple assembly. It meets the requirements for normal riding of beach buggies in harsh outdoor environments, ensuring the safety of the rider.

[0004] However, most existing ATV rear suspension assemblies are connected to the engine via a suspension connection. Over time, the sheet metal connected to the engine is prone to deformation, resulting in low safety and potential chain loosening that affects normal operation. Therefore, this does not meet current requirements. To address this, we have proposed a new ATV rear suspension assembly. Utility Model Content

[0005] The purpose of this utility model is to provide a rear suspension assembly for ATVs to solve the problems mentioned in the background art, where most existing ATV rear suspension assemblies are connected to the engine via a suspension connection method. After long-term use, the sheet metal connected to the engine is prone to deformation, resulting in low safety and the chain may loosen, affecting normal use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rear suspension assembly for a beach buggy, comprising: an engine and a frame, wherein the engine is mounted on the frame, a reinforcing component is provided at the upper end of the frame, the reinforcing component includes a reinforcing plate and screws, and multiple screws are provided, with the screws located at the lower end of the reinforcing plate, the frame includes a base frame and a protective frame, and the protective frame is welded to the upper end of the base frame, a screw hole is provided on the lower surface of the base frame, the screw hole penetrates the base frame, and one end of the screw passes through the screw hole from bottom to top.

[0007] Preferably, a base plate is provided on the lower surface of the reinforcing plate, and the base plate is welded and fixed to the reinforcing plate, and one end of the screw contacts the lower surface of the base plate.

[0008] Preferably, the reinforcing plate has a first shaft groove on both sides near the top, a connecting arm is provided on the side of the reinforcing plate near the first shaft groove, and a second shaft groove is provided on one end surface of the connecting arm.

[0009] Preferably, both sides of the reinforcing component are provided with stabilizing plates, and the stabilizing plates are welded and fixed to the protective frame. A connecting plate is provided on one side of the stabilizing plate, and one end of the connecting plate is connected to one side of the engine. A connecting shaft is provided on one side of the first shaft groove. Both ends of the connecting shaft are provided with second screws. The connecting shaft passes through the first shaft groove and is welded to the reinforcing plate as a whole. After the end face of the connecting plate is fitted with the end face of the connecting shaft, the hole is aligned with the waist arc hole of the stabilizing plate. The other end of the connecting shaft is also aligned with the hole of another stabilizing plate. The two ends are fixedly connected by second screws.

[0010] Preferably, a suspension shaft is provided on one side of the connecting arm, and both ends of the suspension shaft pass through the second shaft groove and are threadedly connected to nuts.

[0011] Preferably, a suspension sheet metal is provided above the suspension shaft, and the suspension sheet metal is connected to the suspension shaft by an external suspension component.

[0012] Preferably, a connecting frame is provided between the upper surface of the base frame and the outer wall of the protective frame, and the two ends of the connecting frame are welded and fixed to the base frame and the protective frame respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model provides a reinforcing component on one side of the engine. The reinforcing component includes a reinforcing plate, a connecting arm, a base plate, and a screw. One end of the screw passes through the screw hole from bottom to top, and the surface of one end of the screw contacts the lower surface of the base plate. The base plate is supported by the screw, thereby supporting the engine. The suspension sheet metal is connected to the suspension shaft through an external suspension component. When the suspension is connected, the force on the suspension is reduced because the screw is pressing against the engine, making it less likely for the suspension sheet metal to deform. This improves the stability of the engine installation and solves the problem that most existing ATV rear suspension assemblies are connected to the engine through a suspension connection method. After long-term use, the sheet metal connected to the engine is prone to deformation, resulting in low safety and loosening of the chain, which affects normal use.

[0015] (2) By setting a stabilizing plate on one side of the reinforcing component, the stabilizing plate is welded and fixed to the protective frame, and connecting plates are set on both sides of the engine. After the connecting shaft passes through the stabilizing plate, connecting plate and the first shaft groove, screws are threaded at both ends, and the stabilizing plate is welded and fixed to the protective frame, the frame, reinforcing component, stabilizing plate, connecting plate and engine are connected, the stability of the connection is improved and it is not easy to loosen.
