Technical Field

The utility model relates to a radiator suspension technical field especially relates to a radiator suspension assembly for heavy truck.

Background

The top end of the existing heavy truck radiator is typically attached to the vehicle body by a boom structure that is fitted with a rubber bushing structure. Due to the assembly mode, the bushing is mainly radially loaded, the rigidity is high, the vibration isolation effect on a system is poor, and the risk that the radiator is damaged under the continuous action of impact load is easy to occur. And the axial of bush lacks effective spacing, and is not enough to the protection of rubber, appears reliability problems such as tensile destruction easily. In addition, traditional radiator suspension bush and skeleton integrated into one piece vulcanize the shaping, and in the vulcanization process, the support also need place in vulcanizing mould, makes its shared volume great, and the vulcanization efficiency is lower, and the cost is higher.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome the not enough of prior art, provide a simple and practical, the vibration isolation is effectual, connect reliable and stable and low in manufacturing cost's radiator suspension assembly for heavy truck.

In order to solve the technical problem, the utility model provides a technical scheme does:

the utility model provides a radiator suspension assembly for heavy truck, includes bush and support, the bush pressure equipment is connected in the connecting seat that sets up on the support, the bush includes the dabber, coaxial cup joints in the outer overcoat of dabber to and fill between dabber and overcoat and with the two rubber layer of vulcanization molding.

As a further improvement of the above technical solution:

the lateral surface of overcoat and the cooperation of connecting seat cup joint, the one end of overcoat is turned over to the outside, forms the flange that the diameter is greater than the internal diameter of connecting seat.

The dabber includes the axis body and two keep off the ring, the rubber layer sets up in the outside of the lateral surface of axis body, two keep off the ring and cup joint respectively in the both ends department of axis body, keep off the diameter of ring and be greater than the external diameter of axis body.

The diameter of the baffle ring is smaller than the inner diameter of the outer sleeve.

The bracket is provided with at least one mounting hole.

Compared with the prior art, the utility model has the advantages of:

the utility model discloses a radiator suspension assembly for heavily blocking, including bush and support, the bush pressure equipment is connected in the connecting seat that sets up on the support, and this kind of mode of setting makes the two can the later stage be connected, consequently need not also put into the mould with the support in the middle of the in-process of preparation bush, occupy small, has reduced the cost of manufacture. The bush includes the dabber, coaxial cup joints the overcoat outside the dabber to and fill between dabber and overcoat and with the two vulcanization fashioned rubber layer, through the wall on rubber layer, can effectively block the transmission of vibration, avoid the radiator to be destroyed.

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully and specifically with reference to the accompanying drawings and preferred embodiments, but the scope of the present invention is not limited to the following specific embodiments.

Example (b):

as shown in fig. 1 and 2, the heat sink suspension assembly for heavy truck of the present embodiment includes a bushing 1 and a bracket 2, the bushing 1 is press-fitted into a connecting seat 21 disposed on the bracket 2, and the bushing 1 and the connecting seat can be post-connected in this way, so that the bracket 2 does not need to be placed into a mold in the process of manufacturing the bushing 1, the occupied size is small, the manufacturing cost is reduced, and the press-fitting connection mode is implemented efficiently. The bushing 1 comprises a mandrel 11, an outer sleeve 12 coaxially sleeved outside the mandrel 11, and a rubber layer 13 filled between the mandrel 11 and the outer sleeve 12 and vulcanized with the mandrel 11 and the outer sleeve 12. Through the partition of the rubber layer 13, the rigidity of the suspension assembly is reduced, and the natural frequency of the system is reduced, so that the vibration impact on the radiator system is effectively attenuated, the transmission of vibration is blocked, and the radiator is prevented from being damaged.

In this embodiment, the outer side surface of the outer sleeve 12 is fitted with the connecting seat 21, and one end of the outer sleeve 12 is turned outward to form a rib 121 having a diameter larger than the inner diameter of the connecting seat 21. The rib 121 serves as a limiting structure, so that effective positioning in the assembling process of the bushing 1 and the support 2 can be achieved, axial play of the bushing 1 from the support 2 can be prevented, axial constraint protection is effectively achieved, and reliability and durability of the radiator suspension assembly are guaranteed.

In this embodiment, the mandrel 11 includes a shaft body 111 and two baffle rings 112, the rubber layer 13 is disposed outside the outer side surface of the shaft body 111, the two baffle rings 112 are respectively sleeved at two ends of the shaft body 111, and the diameter of the baffle ring 112 is greater than the outer diameter of the shaft body 111. In the arrangement mode, the baffle ring 112 can be connected in a press fit mode in the later period, the vulcanization process of the rubber layer 13 cannot be influenced, the axial protection of the rubber layer 13 can be realized, and the rubber damage caused by excessive pulling is prevented. And the retainer ring 112 may also serve as a perforated plane for attachment of fasteners. The retainer ring 112 is made of 45 steel or 20 steel.

In this embodiment, the stop ring 112 has a diameter less than the inner diameter of the outer jacket 12. Therefore, the outer sleeve 12 does not contact the baffle ring 112, and the outer sleeve 12 is connected with the mandrel 11 only through the rubber layer 13, so that abnormal sound or damage caused by direct impact of the outer sleeve 12 and the mandrel 11 is effectively prevented.

In this embodiment, at least one mounting hole 22 is formed on the bracket 2, so as to facilitate the fixed connection of the suspension assembly. The bracket 2 is made of Q355B or other hot-rolled steel plates.

The above description is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art, the modifications and changes obtained without departing from the technical idea of the present invention should be regarded as the protection scope of the present invention.
