[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0019] Embodiments of this utility model: such as Figures 1-4 As shown, a left-side suspension cushion assembly includes a housing 1, a baffle 2 is provided on one side of the housing 1, a rubber main spring 3 is fixedly installed inside the housing 1, and one end of the connecting bracket 4 is fixedly connected to the rubber main spring 3.
[0020] The outer shell 1 is used to fix it to the longitudinal beam of the vehicle body. The rubber main spring 3 inside the outer shell 1 plays the role of support, vibration isolation and limiting. The connecting bracket 4 is used to connect the rubber main spring 3 and the engine assembly. The baffle 2 is set on the side of the outer shell 1 near the longitudinal beam. The baffle 2 and the connecting bracket 4 are on opposite sides of the outer shell 1.
[0021] By setting baffle 2, the rubber main spring 3 and connecting bracket 4 can be effectively prevented from moving towards the longitudinal beam in the Y direction under extreme working conditions, thus achieving Y-direction limiting and preventing the present application from colliding with or interfering with the longitudinal beam of the vehicle frame, thereby ensuring the service life of the present application. Y direction refers to the width direction of the vehicle.
[0022] In one specific embodiment, the outer casing 1 includes a base 5 and a cover 6. The middle part of the base 5 is recessed downward to form a lower receiving space, and the middle part of the cover 6 is raised upward to form an upper receiving space. Two bolt holes 7 are respectively opened at both ends of the base 5 and the two ends of the cover 6. The upper receiving space and the lower receiving space together constitute the receiving space of the rubber main spring 3. The baffle 2 is fixed on one side of the cover 6.
[0023] Two bolt holes 7 at one end of the base 5 and two bolt holes 7 at one end of the cover 6 are coaxially arranged, have the same diameter, and are both circular holes; two bolt holes 7 at the other end of the base 5 and two bolt holes 7 at the other end of the cover 6 are coaxially arranged, have the same shape and size, and are both oblong holes.
[0024] The four bolt holes 7 are used to secure the base 5 and the cover 6 together with bolts, and also to fix them to the longitudinal beams of the frame. One of the bolt holes 7 is designed as an oblong hole to solve the problem of machining errors and prevent the machine from being unable to be installed on the longitudinal beam due to machining errors.
[0025] Furthermore, the lower part of the rubber main spring 3 has two obliquely extending connecting parts 8, which are arranged in a figure-eight shape and are symmetrically arranged with respect to the axis of the rubber main spring 3. The lower ends of the two connecting parts 8 are fixedly connected to the side wall of the lower accommodating space.
[0026] Preferably, the sidewalls of the lower receiving space are inclined surfaces, with the two sidewalls forming an inverted "V" shape. An upward-facing protrusion is formed in the center of the bottom surface of the lower receiving space. This creates a structure where the bottom surface of the lower receiving space is high in the middle and low at both ends, providing better support for the two connecting parts 8. There is a certain gap between the bottom surface of the rubber main spring 3 and the protrusion; the bottom surface of the rubber main spring 3 only contacts the protrusion in an extreme condition. The two connecting parts 8 are vulcanized and fixed to the sidewalls of the lower receiving space. The sidewalls and top surface of the rubber main spring 3 do not contact the top surface and sidewalls of the upper receiving space.
[0027] Preferably, the outer wall of the cover 6 is provided with multiple reinforcing ribs 9. This can enhance the structural strength of the cover 6, prevent damage to the cover 6, and improve its service life.
[0028] The rubber main spring 3 has a trapezoidal mounting hole 10, which is larger at the top and smaller at the bottom, opened horizontally. The connecting bracket 4 includes a horizontal connecting arm 11 and an engine connecting plate 12. One end of the horizontal connecting arm 11 is fixedly connected to the engine connecting plate 12, and the other end of the horizontal connecting arm 11 is inserted into and fixedly connected to the trapezoidal mounting hole 10. The engine connecting plate 12 has four engine fixing holes 13.
[0029] The shape and size of the end of the horizontal connecting arm 11 that connects to the rubber main spring 3 are matched with the trapezoidal mounting hole 10, and the horizontal connecting arm 11 and the rubber main spring 3 are vulcanized and fixed.
[0030] The working principle of this utility model is as follows: First, the base 5 and the cover 6 are fixed to the longitudinal beam of the frame using four bolt assemblies. Then, the left side of the engine assembly is fixedly connected to the engine connecting plate 12 using four bolt assemblies. When the engine assembly is working, it will generate vibration, which will be transmitted to the rubber main spring 3 through the engine connecting plate 12 and the horizontal connecting arm 11. The rubber main spring 3 can absorb the vibration and prevent it from being transmitted to the frame. Under extreme working conditions, due to the baffle 2, the baffle 2 can effectively prevent the rubber main spring 3 and the horizontal connecting arm 11 from moving to the left, which plays a role in Y-direction limiting and prevents collision or interference with the left longitudinal beam.
[0031] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
