Description

Technical Field

[0001] This utility model relates to the technical field of engine fixed support structure, specifically to a three-point engine support structure. Background Technology

[0002] Medium and large engines are mounted on the vehicle. To ensure reliable engine support and reduce the impact of engine vibration on the vehicle, engine support structures are typically arranged at four points: front, rear, left, and right. To achieve vibration damping, damping pads are installed vertically on the supports. However, this four-point engine support damping structure suffers from over-constraint, and its adjustability is significantly reduced when the vehicle frame deforms. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the existing four-point engine support structure has the problem of over-constraint and the adjustment capability is significantly reduced when the frame is deformed.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is to provide a three-point engine support structure, including a body, front suspension supports on both sides of the front end of the body, front suspension pads at the upper and lower ends of the front suspension supports, a flywheel housing at the rear end of the body, two opposing flywheel housing legs at the center of the top of the flywheel housing, and a rear suspension support connected between the flywheel housing legs.

[0005] Optionally, the rear suspension support has a parabolic shape and a mounting hole at its top, which is connected to the flywheel housing support foot by bolts.

[0006] Optionally, a rear suspension pad is provided in the mounting hole. The rear suspension pad includes a vibration damping pad, an inner spacer, and an outer spacer. The inner spacer is clearance-fitted with the bolt, the outer spacer contacts the inner wall of the mounting hole, and the vibration damping pad is filled between the inner spacer and the outer spacer.

[0007] Optionally, the inner spacer sleeve and the flywheel housing support are clearance-fitted in the axial length direction, and the outer diameter of the outer spacer sleeve and the inner diameter of the mounting hole of the rear suspension support are interference-fitted.

[0008] Optionally, an elastic retaining ring is provided between one side of the rear suspension pad and the mounting hole.

[0009] Optionally, the mounting hole edge of the rear suspension support is provided with three grooves.

[0010] In summary, this utility model uses conventional suspension and shock-absorbing support structures on the left and right sides of the front end of the engine, and integrates a single-point support on the flywheel housing at the rear end, which solves the problem of over-constraint of four-point support. The use of a cylindrical sleeve-type shock-absorbing pad structure makes the whole system more stable, improves shock absorption coordination, and effectively reduces the impact of frame deformation on the engine.

[0012] The following combination Figure 1-3 The present invention will be described in further detail below.

[0013] This utility model discloses a three-point engine support structure, referring to... Figure 1 The device includes a body 3. Front suspension supports 4 are provided on both sides of the front end of the body 3. The front suspension supports 4 are existing conventional shock absorption structures. Front suspension pads 5 are provided at the upper and lower ends of the front suspension supports 4. A flywheel housing 2 is provided at the rear end of the body 3. Two opposing flywheel housing feet are provided at the center of the top of the flywheel housing 2. A rear suspension support 1 is connected between the flywheel housing feet. The rear suspension support 1 is a single-point support.

[0014] In a further implementation, refer to Figure 2 and Figure 3 The rear suspension support 1 has a parabolic shape and a mounting hole at its top. The mounting hole is connected to the flywheel housing support foot by bolts 7. The mounting hole contains a rear suspension pad 6, which is a cylindrical sleeve-type shock absorption structure. The rear suspension pad 6 includes a damping pad 6.1, an inner spacer 6.2, and an outer spacer 6.3. The inner spacer 6.2 is clearance-fitted with the bolts 7, and the outer spacer 6.3 is in contact with the inner wall of the mounting hole. The damping pad 6.1 is filled between the inner spacer 6.2 and the outer spacer 6.3. An elastic retaining ring 8 is provided between one side of the rear suspension pad 6 and the mounting hole.

[0015] Specifically, the distance between the two flywheel housing feet matches the length of the rear suspension pad 6, the axial length of the inner spacer 6.2 is clearance-fitted with the flywheel housing feet, the outer diameter of the outer spacer 6.3 is interference-fitted with the inner diameter of the mounting hole of the rear suspension support 1, and three grooves 9 are provided at the edge of the mounting hole of the rear suspension support 1 for removing the rear suspension pad 6 from the mounting hole.

[0016] In use, the front suspension support 4 is installed with the front suspension pad 5 on both sides of the front end of the engine body, and the rear suspension pad 6 is fitted into the mounting hole of the rear suspension support 1. After the elastic retaining ring 8 is installed, a suspension support component is formed. The suspension support component is fitted between the two legs of the flywheel housing 2 and tightened with bolts 7 to complete the installation. This solves the problem of over-constraint of four-point support and effectively reduces the impact of frame deformation on the engine. The overall system is more stable and has better shock absorption coordination.
