Description

Technical Field

[0001] This utility model relates to the field of engine rear suspension technology, and specifically discloses a high-efficiency buffer engine rear suspension. Background Technology

[0002] Shock absorbers are an important component of the engine's rear suspension. Their core function is to balance the vibration transmission of the powertrain with the stability of the vehicle body. Through the synergistic effect of the internal hydraulic damping system and elastic elements, shock absorbers can effectively absorb the impact energy generated by engine operation and road bumps, while suppressing excessive spring rebound and ensuring that the tires always maintain contact with the ground.

[0003] Over time, as the service life of shock absorbers increases, their damping effect will decrease due to reduced rebound, affecting their damping capacity. At the same time, when the vehicle passes over bumpy roads, the damping oil in the shock absorber may overheat during frequent shock absorption, which may also affect its damping effect. Therefore, a high-efficiency rear suspension for engine braking is needed to solve this problem. Utility Model Content

[0004] This invention proposes a high-efficiency buffer rear suspension for engines. When the pressure is applied by the pressure-adjusting pile, the pressure-adjusting pile drives the synchronizing ring and the pressure-distributing frame to press down. This causes the pressure-distributing frame to compress the springs outside the pressure-reducing rods during the pressing process, thereby dispersing the pressing force among the four sets of pressure-reducing rods. This reduces the pressure on the shock-absorbing springs, extends their service life, and solves the problem that excessive wear of the shock-absorbing springs affects the damping effect.

[0005] This utility model is implemented as follows: a high-efficiency buffer engine rear suspension includes a top fixed sleeve, a lifting rod is fixedly connected to the lower surface of the top fixed sleeve, a shock-absorbing structure is rotatably connected to the lower end of the lifting rod, a pressure-inducing pile is fixedly connected to the lower surface of the shock-absorbing structure, an inner sliding sleeve is slidably connected to the outer surface of the pressure-inducing pile, a fastener frame is fixedly connected to the inner surface of the inner sliding sleeve, a heat sink is fixedly connected to the inner surface of the fastener frame, and a heat-conducting plate is fixedly connected to the inner surface of the fastener frame.

[0006] A pressure-relieving rod is fixedly connected to the inner surface of the inner sliding sleeve. A pressure-distributing frame is slidably connected to the outer circumference of the pressure-relieving rod. A moving ring is fixedly connected to the outer surface of the pressure-distributing frame. A pressure-inducing pile is fixedly connected to the inner surface of the moving ring. An oil change cap is snapped onto the inner surface of the inner sliding sleeve. An external structure is fixedly connected to the outer surface of the oil change cap.

[0007] As a preferred embodiment of the high-efficiency buffer engine rear suspension of this utility model, the shock absorption structure includes an upper pressure plate and a shock absorption spring. A lifting rod is rotatably connected to the upper surface of the upper pressure plate, and a shock absorption spring is fixedly connected to the lower surface of the upper pressure plate. An inner sliding sleeve is fixedly connected to the end of the shock absorption spring away from the upper pressure plate.

[0008] As a preferred embodiment of the high-efficiency buffer engine rear suspension of this utility model, the pressure-guiding pile is a circular rod with a length greater than the height of the inner sliding sleeve. The outer circumference of the pressure-guiding pile is provided with an annular groove, and a moving ring is fixedly connected to the inner wall of the annular groove.

[0009] As a preferred embodiment of the high-efficiency buffer engine rear suspension of this utility model, the inner sliding sleeve is a cylindrical tube with four square holes on the outer circumference of the inner sliding sleeve. A fastener frame is fixedly connected to the inner wall of the square holes. The inner wall of the inner sliding sleeve has four arc-shaped grooves. A pressure-relieving rod is fixedly connected to the inner wall of the bottom side of the arc-shaped grooves. A pressure-distributing frame is slidably connected to the inner surface of the arc-shaped grooves.

[0010] As a preferred embodiment of the high-efficiency buffer engine rear suspension of this utility model, the heat sink is a fin, and brass pillars are fixedly connected between the fins. Both ends of the brass pillars are fixedly connected to the fastener frame, and the width of the fin is greater than the width of the inner wall of the fastener frame.

[0011] As a preferred embodiment of the high-efficiency buffer engine rear suspension of this utility model, the heat-conducting plate is an arc-shaped plate made of brass, and heat sinks are fixedly connected to the outer surface of the heat-conducting plate.

[0012] As a preferred embodiment of the high-efficiency buffer engine rear suspension of this utility model, the external structure includes a lower edge pile, an outer extension frame, and a lower fixed sleeve. An oil change cap is fixedly connected to the upper end of the lower edge pile, an outer extension frame is fixedly connected to the outer circumferential surface of the lower edge pile, and a lower fixed sleeve is fixedly connected to the lower surface of the outer extension frame.

[0013] The beneficial effects of this utility model are:

[0014] 1. This high-efficiency buffer engine rear suspension, when pressed down by the pressure-inducing pile, the pressure-inducing pile drives the moving ring and the pressure-distributing frame to press down, thereby causing the pressure-distributing frame to squeeze the spring outside the pressure-reducing rod during the pressing process. This allows the four sets of pressure-reducing rods to disperse the pressing force, thereby reducing the pressure on the shock-absorbing spring and achieving the purpose of extending the service life of the shock-absorbing spring. This solves the problem that excessive wear of the shock-absorbing spring will affect the shock absorption effect.

[0015] 2. This high-efficiency rear suspension for engine damping conducts some of the heat from the damping oil to the cooling fins via a heat-conducting plate. Then, during vehicle movement, airflow carries away some of the heat from the cooling fins, achieving the goal of quickly reducing the heat of the damping oil and solving the problem that slow cooling of the damping oil may lead to a decrease in damping effect.

The outer circumferential surface of the inner sliding sleeve 5 is provided with four square holes. The inner wall of the square holes is fixedly connected with a fastener frame 6.
