Description

Technical Field

[0001] The present application relates to the technical field of automotive component manufacturing, and particularly relates to a rear bracket of a transmission. Background Art

[0002] An engine mount is a bridge connecting the engine and the vehicle frame, which is used to bear the torque and dynamic load output by the engine, isolate the vibration transmitted from the engine to the vehicle body, and can absorb the vibration transmitted from the road surface to improve the riding comfort. The rear bracket of the transmission refers to the engine mount connected between the transmission and the vehicle frame.

[0003] In addition to bearing the torque in the axial direction of the mounting bolts, the rear bracket of the transmission also has to bear the gravity of the engine and the vibration effect during the working process. It is necessary to ensure the connection strength and stiffness of the rear bracket. Usually, a reinforcing rib plate is provided between the two connecting plates. However, in order to reduce the weight of the whole vehicle, weight reduction holes or weight reduction grooves are usually provided on the bracket. For example, the Chinese patent with the authorization publication number CN214138217U and the publication date of October 9, 2020 discloses an engine rear mount assembly, including a mount bracket. First mounting holes and second mounting holes are respectively formed at both ends of the mount bracket. An inner core is connected in the first mounting hole through a mounting colloid, and a vehicle body connection hole is provided on the inner core. A bushing assembly is press-fitted in the second mounting hole with an interference fit, and a rear bracket connection hole is provided on the bushing assembly. The rear bracket connection hole and the vehicle body connection hole are arranged parallel to each other in axis. And sealing glue protrusions protruding outward are formed around the first mounting hole on both end faces of the mount bracket. The outer circumferences at both ends of the mounting colloid extend to the sealing glue protrusions.

[0004] By setting the sealing glue protrusions as described above, it is convenient to position the hand brush and apply the adhesive, avoiding missed coating or overcoating. Regarding the related technology described above, the inventor believes that although the weight reduction holes and through holes in this application can reduce the weight, they will affect the strength of the connection section. Therefore, it is necessary to design a rear bracket of the transmission that can reduce the weight and ensure the connection strength. Content of the Utility Model

[0005] The present application provides a rear bracket of a transmission that can reduce the weight and ensure the connection strength.

[0006] The rear bracket of the transmission provided by the present application adopts the following technical solutions:

[0007] A rear bracket of a transmission includes a first mounting cylinder, a second mounting cylinder, and a connecting plate connecting the first mounting cylinder and the second mounting cylinder. The connecting plate is composed of two pieces and the two connecting plates are parallel to each other. A reinforcing plate is provided between the two connecting plates. The reinforcing plate is a corrugated plate with multiple bends. Reinforcing columns are provided at the bends of the reinforcing plate. The reinforcing columns and the reinforcing plate are both connected to the connecting plate. The first mounting cylinder, the second mounting cylinder, the connecting plate, the reinforcing plate, and the reinforcing columns are integrally formed.

[0008] Preferably, the diameter of the first mounting cylinder is larger than that of the second mounting cylinder. A first rubber sleeve and a second rubber sleeve are respectively clamped in the first mounting cylinder and the second mounting cylinder. A frame connection hole and an engine connection hole are respectively arranged on the first rubber sleeve and the second rubber sleeve.

[0009] Preferably, the axial directions of the first mounting cylinder and the second mounting cylinder are perpendicular to each other. One end of the connecting plate is connected to the side surface of the first mounting cylinder, and the other end of the connecting plate is connected to the end surface of the second mounting cylinder.

[0010] Preferably, the end of the reinforcing plate is connected to the inner side of the connecting plate. The reinforcing columns are located on both sides of the bent portion of the reinforcing plate, and both ends of the reinforcing columns are connected to the connecting plate.

[0011] Preferably, the side surface of the reinforcing plate is connected to the inner side of the connecting plate. The reinforcing columns are located outside the bent portion of the reinforcing plate, and the side surfaces of the reinforcing columns are connected to the connecting plate and the reinforcing plate.

[0012] In summary, the present application includes at least one of the following beneficial technical effects:

[0013] 1. By arranging a reinforcing plate on the connecting plate between the first mounting cylinder and the second mounting cylinder, and setting the reinforcing plate as a corrugated plate with multiple bends, the supporting strength of the connecting plate can be ensured while reducing the weight. At the same time, reinforcing columns are arranged at the bent portions of the connecting plate to improve the overall strength; moreover, the first mounting cylinder, the second mounting cylinder, the connecting plate, the reinforcing plate and the reinforcing columns are integrally formed, and the integrity is good.

[0014] 2. By setting the diameter of the first mounting cylinder to be larger than that of the second mounting cylinder, and at the same time arranging a frame connection hole and an engine connection hole on the first mounting cylinder and the second mounting cylinder, connecting the first mounting cylinder and the second mounting cylinder to the frame and the engine respectively for convenient installation; by setting the angle between the first mounting cylinder and the second mounting cylinder to be perpendicular to each other, combined with the first rubber sleeve and the second rubber sleeve arranged in the first mounting cylinder and the second mounting cylinder, the connection strength and the torsional strength are ensured.

[0015] 3. By connecting the end or the side surface of the reinforcing plate to the inner side of the connecting plate, and at the same time arranging reinforcing columns on both sides of the bent portion of the reinforcing plate, the supporting strength of the connecting plates on both sides is improved, and the overall rigidity is ensured.
