Description

Technical Field

[0002] The statements in this part only provide background technical information related to the utility model, and do not necessarily constitute prior art.

[0003] The engine compartment space of a small loader is limited, and it is very difficult to select the assembly position of the air-conditioning compressor, and it is mostly close to high-temperature components (engine exhaust system), resulting in a short service life of the compressor and poor refrigeration effect.

[0004] The existing assembly position of the air-conditioning compressor is as Figure 1 shown. An engine shock absorber mounting bracket 01 is provided at the lower part of the engine main body; the assembly position of the air-conditioning compressor 02 is at the upper part of the engine main body, close to the engine exhaust pipe 03. The distance between the air-conditioning compressor 02 and the driving wheel 04 located at the lower part of the engine main body is relatively far, and a relatively long belt needs to be assembled; however, if a relatively long belt is selected, the assembly requirements are high, and it is easy for the belt to break if the assembly deviation is not well controlled.

[0005] Moreover, the air-conditioning compressor will generate vibration during operation. If the air-conditioning compressor and the engine are installed on the same plane, the vibration will be transmitted and cause resonance between the two, affecting the operation stability of the equipment. Summary of the Utility Model

[0006] To overcome the deficiencies of the above-mentioned prior art, the utility model provides an integrated engine support structure for a small loader.

[0007] To achieve the above object, one or more embodiments of the utility model provide the following technical solutions:

[0008] The first aspect of the utility model provides an integrated engine support structure for a small loader, including: a fixing plate, an engine shock absorber mounting plate, and an air-conditioning compressor mounting plate;

[0009] The fixing plate is vertically arranged at one end of the lower part of the engine main body close to the engine driving wheel. On the side of the fixing plate away from the engine main body, there are an engine shock absorber mounting plate and an air-conditioning compressor mounting plate, and there is a height difference between the engine shock absorber mounting plate and the air-conditioning compressor mounting plate;

[0010] An installation hole is provided in the middle of the engine shock absorber mounting plate, and one end of the engine shock absorber is arranged in the installation hole; the bottom of the air-conditioning compressor is arranged on the upper surface of the air-conditioning compressor mounting plate.

[0011] Further, both the engine shock absorber mounting plate and the air-conditioning compressor mounting plate are vertically arranged with respect to the fixed plate.

[0012] Further, the upper surface of the air-conditioning compressor mounting plate is provided with a vertically arranged first support plate and a second support plate at intervals, and the first support plate and the second support plate are used for supporting and fixing the air-conditioning compressor.

[0013] Further, the first support plate is a triangular plate, and a bolt hole for connecting with the base of the air-conditioning compressor is opened in the upper part of the triangular plate.

[0014] Further, the second support plate is an L-shaped plate; the side part of the L-shaped plate is connected with the fixed plate, and the bottom part of the L-shaped plate is connected with the air-conditioning compressor mounting plate.

[0015] Further, an arc-shaped groove matching the shape of the air-conditioning compressor is opened in the contact part of the second support plate with the air-conditioning compressor.

[0016] Further, a reinforcing plate is further provided on the side of the fixed plate away from the engine main body.

[0017] Further, the reinforcing plate includes a first reinforcing plate and a second reinforcing plate, and the first reinforcing plate and the second reinforcing plate are respectively arranged on both sides of the engine shock absorber mounting plate;

[0018] The bottom of the first reinforcing plate is connected to the engine shock absorber mounting plate, and the bottom of the second reinforcing plate is connected to the air-conditioning compressor mounting plate.

[0019] Further, the air-conditioning compressor mounting plate and the fixed plate are integrally formed, and the connection part between the air-conditioning compressor mounting plate and the fixed plate is an arc-shaped transition structure.

[0020] Further, the installation height of the engine shock absorber mounting plate is higher than the installation height of the air-conditioning compressor mounting plate.

[0021] The above one or more technical solutions have the following beneficial effects:

[0022] (1) In the present utility model, the air-conditioning compressor mounting bracket is integrated onto the engine bracket, so that an integrated bracket can meet the installation functional requirements of two components; and the integrated engine bracket structure is installed at one end of the lower part of the engine main body close to the driving wheel. By adjusting the installation position of the air-conditioning compressor, it is separated from the exhaust pipe on the engine main body and close to the driving wheel of the engine main body; not only can its service life be extended and the influence of the surrounding environment on its refrigeration effect be reduced, but also the length of the belt on the air-conditioning compressor can be reduced and the belt assembly error can be reduced.

[0023] (2) Considering the severe vibration generated during the operation of the air-conditioning compressor, in the integrated engine mount structure provided by the present utility model, there is a design with a certain height difference between the engine shock absorber mounting plate and the air-conditioning compressor mounting plate, which can effectively prevent resonance.

[0035] The fixing plate 3 is vertically arranged at one end of the lower part of the engine body close to the engine driving wheel, and the side of the fixing plate 3 away from the engine body is provided with an engine damper mounting plate 1 and an air conditioning compressor mounting plate 2, and there is a height difference between the engine damper mounting plate 1 and the air conditioning compressor mounting plate 2;

[0036] The engine shock absorber mounting plate 1 and the air-conditioning compressor mounting plate 2 are located on the same side, and the engine shock absorber mounting plate 1 and the air-conditioning compressor mounting plate 2 are used to fix the engine shock absorber and the air-conditioning compressor respectively;

[0037] Among them, a mounting hole 101 is opened in the middle of the engine shock absorber mounting plate 1, one end of the engine shock absorber is fixed in the mounting hole 101 by bolts, and a rubber gasket is also provided on the mounting hole 101 to reduce friction and prevent loosening; the bottom of the air-conditioning compressor is fixedly set on the upper surface of the air-conditioning compressor mounting plate 2.

[0038] The utility model integrates the air-conditioning compressor mounting bracket into the bracket of the engine shock absorber, so that one integrated bracket meets the mounting function requirements of the two components.

[0039] The integrated engine bracket structure is installed at the bottom of the side of the engine body. By adjusting the installation position of the air-conditioning compressor, it can be separated from high-temperature components, extending its service life and reducing the impact of the surrounding environment on its cooling effect. In addition, by adjusting the installation position of the air-conditioning compressor, the length of the air-conditioning compressor drive belt can be shortened, reducing the difficulty of assembly and the failure rate of belt breakage.

[0040] As a further technical solution, the engine damper mounting plate 1 and the air conditioning compressor mounting plate 2 are both arranged vertically to the fixing plate 3 , and the mounting height of the engine damper mounting plate 1 is greater than the mounting height of the air conditioning compressor mounting plate 2 .

[0041] Taking into account the violent vibrations generated during the operation of the air-conditioning compressor, in the integrated engine bracket structure provided by the utility model, the bottom surface of the engine damper mounting plate and the bottom surface of the air-conditioning compressor mounting plate are designed with a certain height difference, which can effectively prevent resonance.

[0049] The bottom of the first reinforcing plate 6 is connected to the engine shock absorber mounting plate 1, and the bottom of the second reinforcing plate 7 is connected to the mounting plate 2 of the air conditioner compressor; by setting the reinforcing plate, not only can the bracket structure be stabilized, but also the isolation between the air conditioner compressor and the engine shock absorber can be realized.

[0050] As a further technical solution, the mounting plate 2 of the air conditioner compressor and the fixing plate 3 are of an integrally formed design, and the connection part between the mounting plate 2 of the air conditioner compressor and the fixing plate 3 is an arc-shaped transition structure (i.e., an arc-shaped chamfer).

[0051] A number of bolt holes are provided on the fixing plate 3, and the fixing plate 3 is fixedly arranged on the engine body through bolts; the upper part at one end of the fixing plate 3 close to the driving wheel arranged on the engine body is a cut-off structure, and one end of the first support plate 3 and the second support plate 4 close to the fixing plate 3 is a cut-off structure, aiming to reduce the weight of the bracket on the premise of ensuring stability.

[0052] Such as Figure 5As shown, the integrated engine support structure for the small loader provided in this embodiment is fixedly arranged at one end near the driving wheel at the lower part of the engine body through bolts; by adjusting the installation position of the air conditioner compressor, making it away from the exhaust pipe at the upper part of the engine body and close to the driving wheel at the lower part of the engine body; the driven wheel of the air conditioner compressor can be connected to the driving wheel on the engine body through a belt with a shorter length.
