Description

Technical Field

[0001] This utility model belongs to the field of vehicle shock absorption technology, and in particular relates to the upper top mount assembly. Background Technology

[0002] The top mount assembly is a key component used in automotive suspension systems or body support structures. It is mainly used to connect the vehicle body to the chassis or other related components, and also has functions such as support, shock absorption and positioning.

[0003] In the current technology, the assembly of the top mount assembly with other components, such as the suspension system or body frame, often relies on manual alignment or other external auxiliary tools, lacking a precise positioning structure. Therefore, assembly errors are prone to occur. During vehicle operation, due to the influence of dynamic loads such as vibration and impact, the top mount assembly may easily shift in position due to initial assembly errors or uneven force.

[0022] The upper top seat body 10 and the limiting liner 20, the upper top seat body 10 includes a cylindrical part 11 and a connecting part 12, the connecting part 12 is coaxially arranged with the cylindrical part 11 and the connecting part 12 is located above the cylindrical part 11;

[0023] The connecting part 12 has an upper boss 13 at its center, and a positioning groove 131 is provided at the center of the upper boss 13. The axis of the positioning groove 131 coincides with the axis of the upper top seat body 10.

[0024] The limiting pad 20 includes a skeleton 21 and a rubber body 22. The skeleton 21 is fixedly disposed on the outer side wall of the cylindrical part 11, and the rubber body 22 covers the outside of the skeleton 21.

[0025] The central axis of the upper seat body 10 is as follows Figure 2 As shown by the dashed line L, the cylindrical part 11 serves as the main support, playing a role in bearing and connecting; the connecting part 12 is annular in shape and is used to connect with other components.

[0026] The positioning groove 131 at the center of the upper boss 13 is cylindrical. The axis of the positioning groove 131 coincides with the axis of the entire upper top seat body 10, ensuring the symmetry and stability of the structure. The positioning groove 131 is used to accurately position related components, prevent the upper top seat body 10 from shifting on the car chassis, improve the fixing effect of the upper top seat body 10, realize precise assembly with other components, and reduce assembly errors.

[0027] Specifically, the upper end face of the upper boss 13 has a chamfered side, and the positioning groove 131 is set as a circular arc groove with the flaring direction of the positioning groove 131 away from the central axis.

[0028] The skeleton 21 of the limiting pad 20 is fixed to the outer wall of the cylindrical part 11 to provide rigid support, and the rubber body 22 plays the role of buffering, shock absorption and anti-slip.
